How to choose the right cushion hydraulic cabinet door hinge

Buffer hydraulic cabinet door hinge refers to a kind of hydraulic buffer hinge that provides a kind of buffering performance that utilizes liquid, and the buffering effect is ideal, and the utility model discloses comprises a bearing, a door box, a buffer, a connecting block, a connecting rod and a torsion spring, and one end of buffer is hinged on the bearing; The connecting block middle is hinged on the bearing, and one side is hinged with the door box, and the piston rod of the other side of the buffer is hinged; The connecting block, the connecting rod, the bearing, and the door box form a four-link mechanism; The buffer consists of a piston rod, a housing, and a piston. The piston is provided with a through hole and a hole, and when the piston rod drives the piston to move, the liquid can flow from one side to the other through the through hole, thus playing a cushioning role.

Because of its more humanized characteristics: supple and silent, not easy to pinch people, the cushion hydraulic hinge has a strong impact on the people who move to a warm, harmonious and safe home, so once this hinge is launched on the market, it is the favor of decorators and has attracted countless eyeballs.

With the increase of users, manufacturers are also increasing, under the tide of market economy, shoddy in the continuous emergence, many consumers after using it are said that soon there is no hydraulic function, several times more expensive buffer hydraulic hinge has only been used for less than a few months and ordinary hinges are no different, how can it not be sad? There is even equipment for the user's room after not using this hinge, this situation is a bit like the alloy hinge a few years ago, and the hinge made of scrap materials has been broken when the screw is on, so that many loyal consumers of alloy hinges "turn a blind eye" to the alloy hinge and turn to the ranks of iron hinges, and finally the alloy hinge market continues to shrink, so here is also a word to the manufacturers of buffer hydraulic hinges, do not hurt the hearts of consumers for temporary profits, in the era of information asymmetry, In the case that consumers can't distinguish the worst, manufacturers must take responsibility for quality, and ultimately achieve a win-win situation between the market and profits.

To choose the best cushion hydraulic hinge:

1.Appearance, the products produced by manufacturers with mature technology will pay more attention to the appearance, and the first bar and the surface will be treated better, except for the general scratches, there is no deep digging traces, which is the technical advantage of the strength of the manufacturer.

2.The speed of closing the door is uniform, pay attention to whether the buffer hydraulic hinge is open and close with the feeling of card, if you hear a strange sound, or the difference between speed and speed is too large, you should pay attention to the difference in the choice of hydraulic cylinder.

3.Anti-rust, with salt spray test can be seen its anti-rust ability, after 48 hours of rust is rarely seen in the case.

Tips for choosing hydraulic hinges

Because the hinge is switched on average more than 10 times a day in everyone's life, the quality of a hinge depends on the performance of your furniture. Basically, you can tell the good or bad of the hinge from the following aspects:

1. Surface:

Look at whether the surface material of the product is flat, if you see scratches and deformation, it is produced from waste (leftovers), this kind of hinge has an ugly appearance, so that your furniture is no grade.

2. Hydraulic performance:

We all know that the hinge is the function of a switch, so this is very important, the key is taken from the damper of the hydraulic hinge, as well as the rivet assembly. The damper mainly looks at whether there is noise when opening and closing, if there is noise, it is an inferior product, and whether the round speed is uniform. Is the hinge cup loose?

If the ear is loose, it proves that the rivet is not tightly riveted and is easy to fall off. Close it a few times and see that the indentation in the cup is not obvious. If it is obvious, it proves that there is a problem with the thickness of the cup material, and it is easy to "burst the cup".

3. Screws:

Generally, the hinge comes with two screws, all of which belong to the adjusting screws, the upper and lower adjustment screws, the front and rear adjustment screws, and the hinge with a higher edge also has the left and right adjusting screws, which is now the so-called three-dimensional adjustment hinge, generally with two adjustment stations.

Tip, use a screwdriver to adjust the screws up and down three to four times with a little force, and then remove the screws to see if the teeth of the hinge arm are damaged, because this hinge arm is formed out of iron materials, not as hard as the screws, easy to wear, and because of the factory tapping if the accuracy is not enough, it is easy to slip, or can not be screwed. The front and rear adjustment screws are also tested as follows.

Installation method of hydraulic hinges

Step 1: According to the needs of cabinet design, the door panel is a full cover, half cover or built-in door panel, respectively, the hinge is selected: straight bend, medium bend or large bend;

Step 2: Determine the margin of the cup hole according to the thickness of the side panel, and make a hinged cup hole on the door panel, the side panel is 16mm or 18mm, and the margin is usually 5mm;

Step 3: Put the hinge cup into the cup hole of the door panel, the hinge is 90 degrees to the edge of the door panel, and then use 4x16mm self-tapping screws from the hinge cup'The two screw holes are locked with a screwdriver;

Step 4: Move the door panel with locked hinges to the cabinet, align the side panels, and put two long holes on it first, and test whether the top and bottom are aligned? At this time, the door panel can be moved up and down to reach the best position, and then a good round hole can be installed;

Step 5: Debugging, first loosen a small screw on the hinge, mobilize the big screw in front of it, so as to adjust the suitability of the side plate of the hinge cover, and then use the small screw to loosen the front and back to adjust the tightness of the door panel and the side panel;

Step 6: Test, test whether it is adjusted well or not by using the experience, and then re-debug through the instructions in step 5 until it is qualified.

Caused by an oil leak.

When the shock absorber is subjected to collision pressure, the kinetic energy is transferred to the piston through the plug head and the acceleration spring, causing it to move to the right. Originally, the working chamber of the buffer was equipped with a return spring, ejector rod and oil. The movement of the piston squeezes the oil in the working chamber to compress its return spring, and at the same time squeezes the oil out of the annular gap between the piston and the push rod and enters the oil storage chamber.

When the piston starts to move, the oil is easily squeezed out due to the large annular gap between the piston and the ejector rod; As the piston continues to move, this annular clearance becomes smaller and smaller, i.e. the piston resistance increases until the cylindrical stage of the ejector rod reaches zero and the resistance is stabilized at the maximum. The process by which the buffer is compressed is the process of doing work by the piston squeezing the oil. This process consumes a lot of kinetic energy and acts as a buffer.

When the work is complete, the piston is pushed to the original position by the return spring, completing a working cycle.

1, the best hinge on the market is Blum, said to be made in Austria, in fact, it is really not suitable for us to use, 2, a price is too expensive, the purchase price is about 20 a, and there is an external buffer, divided into a full cover, half a cover, not covered, there is also a small bend in the big bend, the usual purchase price is more than 10 yuan, but the additional buffer is very expensive, a buffer in the big bend to the purchase price of about 46 yuan, 3, plus the buffer Blum only two hinge holes, accidentally loose, 4, the domestic is now also in a lot of good brands, as well as all stainless steel, the selling price is about 15 yuan a, very easy to use, I have been making cabinets for more than ten years, used for six or seven years, there has never been any problem, that is, the selling price of about 10 domestic hinges are also very easy to use, that is, by the sink sometimes rusty.

There are several ways to choose a better quality door cushion hinge.

1. Look at the appearance, take a few more hinges**, see whether the appearance of the hinges is roughly maintained to, many poor hinge factories produce hinges here black and yellow, electroplating is unstable, and the electroplating layer is thin, so it is easy to rust.

2. Hold the hinged iron cup, slowly close the hinge like a closed door, remember to be slow, if you feel that the hinge is very smooth, there is no obstacle, and even try a few are very smooth, then the hinge product is preliminarily qualified. If you notice that there is an obstruction or a sound in the middle, or even both, then you should be careful about whether the hinge has a quality problem.

3. After installing the door, press down a little hard to see how the force of the hinge is, if it is easy to sink and more serious, then you have to be careful that the door panel will appear asymmetrical in the future.

4. Test its durability with a professional fatigue testing machine and test its rust resistance with a salt spray tester. This is not something that the average consumer can achieve.

5 Use a screwdriver to try a few more adjusting screws of the hinge and the fastening screws at the end of the hinge to see if it is easy to slip teeth, if it is easy, it should be noted that such a hinge is very troublesome to use One can not be adjusted, two is not stable, this is only a sigh I hope it can help you.

Hinge purchase: hinge is the key to each piece of furniture, because hinges in everyone's life on average more than 10 times a day, so the quality of a hinge depends on the performance of your furniture, choose your own home hinge hardware also need to pay great attention. Basically, you can tell the good or bad of the hinge from the following aspects:

1. Surface: Look at whether the surface material of the product is smooth, if you see scratches and deformation, it is produced from waste materials (leftovers), this kind of hinge has an ugly appearance, so that your furniture has no grade. Surface Treatment:

Most of the hinges are nickel plated, and now due to the very js low cost, only a thin layer of nickel plating, the real hinge should be plated with a layer of acid copper before the nickel plating layer, which can be very good anti-rust, tips: teach you a way to distinguish whether there is copper plating: if js does not object, you can use the art force to draw a knife, see if you can see the yellow copper layer, there is a more intuitive way, is to look at the hinge cup, the hinge cup is generally recessed, here is also the most difficult place to plate, If the cup shows the same black water performance or can see the iron color, it proves that the plating layer is very thin, and there is no copper plating.

Isn't it simple?

2. Switch performance: We all know that the hinge is the role of a switch, so this is very important, the key is taken from the outer spring and inner spring of the hinge, as well as the rivet assembly. The outer spring is a spring sheet, the inner spring is a spring bar, all of which have to go through a certain amount of heat treatment, too hard and easy to break, too soft to close the door without strength, some JS purchases low-cost spring accessories, resulting in not being able to close the door panel well, or the spring is broken and the door panel falls off.

Tip: When buying hinges (except for hydraulic hinges), close the hinges by hand, and listen to the sound of the hinges closing, is it crisp? Kiyosuke is good, if it is a dull closing sound, it proves that the spring strength is not enough, and there is a problem with the thickness of the material.

Is the hinge cup loose? If there is looseness, it proves that the rivet is not tightly riveted and is easy to fall off. Close it a few times and see that the indentation in the cup is not obvious.

If it is obvious, it proves that there is a problem with the thickness of the cup material, and it is easy to "burst the cup".

3. Screws: Generally, the hinge comes with two screws, which are all adjustment screws, up and down adjustment screws, front and rear adjustment screws, and some ** hinges also have left and right adjustment screws, which are now the so-called three-dimensional adjustment hinges, generally with two adjustment stations. Tip, use a screwdriver to adjust the screws up and down three to four times with a little force, and then remove the screws to see if the teeth of the hinge arm are damaged, because this hinge arm is formed out of iron materials, not as hard as the screws, easy to wear, and because of the factory tapping if the accuracy is not enough, it is easy to slip, or can not be screwed.

The front and rear adjustment screws are also tested as follows.

After reading it, you can basically become an expert in choosing hinges, isn't it very simple...

The domestic hydraulic hinge is divided into three major production areas, according to the grade, namely: first, Shunde, Guangdong, the quality is relatively good, the price is the highest. There are many big brands and simple packaging.

Second, Guangdong Gaoyao Jinli, the quality is medium and high-end, the best is moderate, and the packaging is simple. Third, the Jieyang area of Guangdong, the quality is the worst, the lowest and the packaging is the best.

Look at the workmanship material, ordinary hinges can be tried to close to listen to the sound, whether there is strength. The hydraulic hinge looks at the speed of closing, not too fast.
