Why do foreign cabinets use two in one connectors 5

In the production of panel furniture, most enterprises use the traditional three-in-one connector, while in Europe and some domestic enterprises with higher requirements for product quality and larger output use two-in-one connectors, so what are the benefits of using two-in-one connectors? Let's compare it with the use of 3-in-1 connectors and do a simple analysis. 3-in-1 by nylon embedded parts.

Tie rod, eccentric parts three parts, the weakest link in this connection structure is the combination of embedded parts and plate holes, considering the characteristics of nylon, the outer diameter of nylon embedded parts produced by regular manufacturers d=", furniture panels.

The reserved aperture d=10mm, relying on the extrusion of the hole wall by the embedded parts, produces friction when it is stretched.

Thus play the role of connection, but when the embedded parts are driven, the hole has been greatly damaged, the hole wall becomes loose, and the embedded parts are easy to loosen and fall out. The two-in-one connector is composed of two parts: tie rod and eccentric part, and the thread of the tie rod adopts a European-style screw structure, that is, the outer diameter of the screw tooth and the inner diameter of the thread

Spp. distance =""mm, the plate hole is required to be 5mm, the tie rod is screwed into the 5mm hole, the mm high tooth is embedded into the hole wall, which can withstand greater tension, because the screw distance is larger, the plate hole will not be damaged, and the firmness will not be affected even if it is disassembled and assembled many times. The three-in-one embedded part has a large reserved hole, which is close to the edge of the plate, and the following situations are prone to burst and bulge on the edge of the board: 1

The embedded parts are not standard, and the outer diameter is large; 2.The drill bit is worn, and the plate hole becomes smaller; 3.Nylon pieces harden at low temperatures (non-nylon parts are not affected, but the toughness is not good).

The two-in-one reserved hole is smaller, and the screw rod can be screwed directly without the above problems. From the cost point of view, the three-in-one ** is higher than the two-in-one, because of the more nylon embedded parts of the product, in the transportation, warehouse management and other links will increase additional expenditures, the most important thing is in the assembly process greatly increased the workload, to each embedded parts with 10 seconds calculation, a factory monthly consumption of 250,000 sets of three-in-one: (10,000 10 seconds) (3600 seconds 2 hours) = working hours and the use of two-in-one plus connectors, will save this cost.

To sum up, in the production process, the use of two-in-one connection is a great advantage, of course, it is also necessary to decide whether to use it according to the product produced and the material of the plate.

Judging from your description, it should refer to the American cabinet, the American cabinet is a special one in the cabinet industry, in addition to the use of two-in-one, there are also 12mm plywood for the cabinet body, 5mm plate for the back plate to be thickened around the board, solid wood for drawers with dovetail structure, solid wood frame for the front mouth, etc., are the fixed mode of American cabinets. American furniture is characterized by very little structural change, and a piece of furniture remains unchanged for decades or even centuries.

The Chinese cabinet industry started with the European standard, mainly introduced by Hong Kong designers, so many years of development are in accordance with the European model, and the European model, the shape of the cabinet changes colorfully, but also suitable for the needs of the Chinese market, therefore, the structure of the European model has also continued to the present.

Cabinets are generally connected in three-in-one, and wardrobe partitions are generally connected in two-in-one. Mainly panel cabinets are easy to assemble. It is connected with screws and is strong, but the error is large, the efficiency is not high, and it is not beautiful. Complete!

Three-in-one screw and two-in-one composite screw.

The function of the silk is to connect the planks, and there is not much difference in this regard. There are many related factors for the stability of the furniture connected by the connector, one is that the connection structure is very important, and different connection structures or connectors should be selected for different stress parts and force sizes to ensure the connection strength; The second is the number of connectors, which will also play a great role in the stability of the connection strength.

The main differences between them are as follows:

1. There is a difference in punching and a difference in appearance: the two-in-one screw opens through the hole, and inserts the hammer nut through the wooden board to connect the other side from the other side. But the three-in-one expansion plug is a half-hole, so there is a problem:

The eccentric wheel of the three-in-one screw and the two-in-one hammer head are both in the dark and cannot be seen from the outside, but the two-in-one screw is exposed on the outside because it penetrates the wooden board, so the screw head is exposed outside, and the appearance is not as beautiful as the three-in-one.

2. The connection strength is different: the two-in-one screw is a screw directly connected to the nut to connect the wooden board together, so the connection strength is much higher than that of the three-in-one through the plastic expansion plug, which is what the people say is strong.

Normal panel furniture uses more three-in-one, a rubber stopper (called peanuts in some factories in Beijing), a snake cake, and a screw.

Taotao Jiangshui is right, the three-in-one strength is high, but the cost is high, and it is only suitable for the disassembly and assembly of plates above 15mm.

It's not a question of whether it's good or not, the two-in-one is suitable for the connection of the 12 centi-plate, the three-in-one is suitable for the connection of the board above 15 centi, the force should be the strong point of the three-in-one, and the two-in-one is generally used for the connection of drawers and backplates!!

Quote:ԭ wenhuishui 2008-6-9 11:40 This is not a question of whether it is good or bad, the two-in-one is suitable for the inner connection of the 12 centi-plate, the three-in-one is suitable for the connection of the board above 15 centi, the force should be three-in-one strong point, the two-in-one is generally used for drawers, the connection of the back plate!!

That's right!

Is there only a combination of these two ways to be beautiful? Don't want to forge ahead.

If the source is from the cost of use, the two-in-one connector of panel furniture is lower than the three-in-one connector**.

In terms of use effect: 1. The two-in-one connector is composed of two parts: tie rod and eccentric part. The thread of the tie rod adopts a European-style screw structure, which can withstand greater tension, and because of the large pitch, it will not cause damage to the plate hole, and it will not affect its firmness even if it is disassembled and assembled many times.

2. The two-in-one reserved hole is small, and the screw can be screwed in directly, and there will be no bursting and protruding phenomenon on the edge of the plate.

So the 2-in-1 is also relatively convenient to use!

Cabinets are generally connected in three-in-one, and wardrobe partitions are generally connected in two-in-one. Mainly panel cabinets are easy to assemble. Connect with screws.

It is strong, but the error is large, the efficiency is not high, and it is not beautiful. Complete!

It is good to use connectors, beautiful, easy to disassemble, and it is firmer than grabbing nails, and if you want to be more firm, you can use self-tapping wire, but it is not good-looking.

Each has its own benefits, depending on what you want to use, it is recommended that you use nails to use *** nails, like the nails of the open source pneumatic nail industry, affordable and durable.

Method 1: The quality of the plate is very important.

Look at the quality of the plate, the edge banding should be delicate, smooth, good feel, horizontal and vertical, fine joints, and uniform gluing.

Brand products with a linear edge banding machine to complete the edge banding, breaking, trimming, chamfering, polishing and other processes, the pressure of pressing edge banding is stable, the accuracy of the processing size can be adjusted to the most suitable part, to ensure the most accurate size, and the quality is stable.

Unlike the small workshop The quality of the workshop is completely determined by the master's craftsmanship and working status, the small factory is glued with a brush, manually pressed and pasted the edge, trimmed with a wallpaper knife, and polished with a manual polishing machine.

Method 2: The perforation level relates to the firmness of the box structure.

Plate furniture are assembled by three-in-one connectors, need to make a lot of positioning holes on the plate, the coordination and accuracy of the hole position will affect the structural firmness of the cabinet box, professional manufacturers use multiple rows of drills to complete all the holes on the edge of a board and the board surface, the positioning benchmark is unified, the size is high, and the small factory uses a row drill or hand drill to gradually punch holes, which is easy to produce large errors.

Method 3: The cutting accuracy of the cutting board is high.

Cutting of the plate is also a very important procedure. Professional large factories use electronic cutting saws to input processing dimensions through the computer, and the size and accuracy are controlled by the computer, and a number of plates are processed at a time, the specifications are very uniform, stable, the tolerance is small, and the edge of the plate is not broken, if the small factory can not do these requirements.

Method 4: The choice of door panel is very important.

The door panel is the face of the cabinet, a good door panel is colorful, bright, not easy to fade, not easy to be deformed by moisture, not easy to bulge at the edge, not easy to penetrate into stains and oil stains, not easy to appear scratches and hard wounds.

Method 5: The assembly effect of the whole set of cabinets.

Any size error in the production process will lead to obvious discomfort in the assembled cabinet on the door panel, the door panel should be horizontal and vertical, the gap between the door panel is uniform and uniform, and it looks very neat.

Method 6: Look at the slide of the drawer.

This is an important part of the future use, the quality of the hardware of the cabinet directly affects the future use, and it is also an important part of the cabinet **. The size of the hole and the size of the plate will affect the installation of the hardware, and any potential non-conformity will cause the drawer opening and closing to be inconvenient, easy to loosen, transposition, large cracks, and louder and louder.

The above are the six methods of choosing cabinets, I believe that as long as the owner masters these, pay attention to the details mentioned in the article when choosing cabinets, it is not difficult to buy good cabinets! Creating the perfect kitchen starts with picking a good cabinet!

At present, there are several specifications of 18 plates and 16 plates.

18. The commonly used kits for plates are: eccentric head 15* screw 40mm 36mm embedded parts 10*10mm 10*12mm

Eccentric head 15*12mm screw 40mm 36mm embedded parts 10*10mm 10*12mm

16. The commonly used kits for plates are: eccentric head 15*12mm screw 40mm 36mm embedded parts 10*10mm 10*12mm

This is a general furniture or cabinet manufacturer, however, manufacturers who directly do real estate decoration projects generally use two-in-one connectors.

The main thing is that the screw is different The common two-in-one screw is: 45mm 35mm

Bamberg, my countertop is made of 304 stainless steel, which can be moisture-proof, even if a large pile of water stains is sprinkled on it, it can not be dripped in, and the cabinet plate has high strength, not afraid of scratches, and some small bumps will not cause any damage to the cabinet at all.
