What is the principle of anti theft lock of anti hydraulic shears

Anti-theft lock of hydraulic shears: According to the principle of the lock cylinder, the anti-theft lock can be divided into bullet lock, blade lock, magnetic lock, IC card lock, fingerprint lock, etc.

First, the lock body material this involves a lot of professional knowledge and the technology of various manufacturers, the mainland is generally iron, steel, stainless steel, zinc alloy, due to the process, cost limitations, the hardness of the lock rod is not enough, often easy to be cut by forceps, hydraulic pliers.

Second, the lock cylinder is generally bought by people who only look at the appearance, and they think that it must be good if it is very big. But no matter which kind of domestic lock you buy, the lock cylinder is generally copper, and the characteristics of copper are soft, and you can easily destroy the copper lock cylinder with an electric drill and concentrated flow acid. There are also differences in the types of lock cylinders, the more commonly used lock cylinders are European-style lock cylinders, in addition, there are American threaded lock cylinders, fireproof lock cylinders, the latter two have relatively high security, American lock cylinders are used in high-grade door locks, ***, high security, fireproof lock cylinders are used in fireproof door locks, can withstand high temperatures of 975 degrees for 90 minutes, and are special door lock cylinders enforced by the state.

Third, the key, the key of the lock has a lot, cross, round, crescent, various, many keys are made of copper or aluminum-iron alloy, which is easy to be copied, the better materials are steel, and there are new electronic keys, with higher security.

1. The concept of liquid, the landlord should know, which is no longer explained;

2. Hydraulics, that is, the pressure of liquids;

3. Scissors, such as scissors and the like, but their shear force is generated by hydraulic pressure, while scissors are generated by hand.

Combining the above concepts, that is, a device that uses the force generated by liquid pressure to cut is called hydraulic shears.

The principle of hydraulic shears: that is, Pascal's principle.

To put it simply, hydraulic scissors are devices that use hydraulic oil as the working medium to transmit torque to make the shear surface produce huge shear force, and there is a distinction between manual and electric.

The self-locking system of hydraulic scissors prevents the hydraulic scissors from being unintentionally caused by ignorant children or people.

The anti-hydraulic shear lock should be the lock that cannot be cut and destroyed by using hydraulic shear continuously; The anti-hydraulic shear lock is a lock that the lock beam cannot be put into the hydraulic shears and cannot be started with the hydraulic shears, such as the disc lock of a motorcycle.

Cut directly. In the event of fire, traffic accidents, ** and other disasters, the product can quickly and effectively cut metal or non-metallic structures such as anti-theft doors and windows, steel bar protective railings, automobiles, train carriages, etc.;

To rescue victims trapped in confined environments or to rescue victims in dangerous environments for the purpose of rescue or disaster relief. It is a necessary demolition tool for fire brigades, traffic police teams, industrial and mining enterprises and other disaster relief and rescue departments.

How it works. Hydraulic shears usually have an aluminum alloy shell, and its blade is forged from hot-rolled steel. Pistons and piston actuators are usually made of hot-rolled alloy steel. Hydraulic shears are mainly used to cut materials such as sheet metal and plastic.

Usually, they are used to cut cars as well as other means of transportation to rescue trapped passengers. Like the hydraulic spreader, the hydraulic shears can also be powered by a gasoline drive. The life-saving jaw system can be electric, air, or hydraulically driven.

Unlike hydraulic dilators, hydraulic shears are curved claw-like extensions, and it ends in a pointed shape. As with hydraulic expanders, hydraulic fluid flows into the cylinder and then exerts pressure to the piston. The opening and closing of the blade depends on the direction of the power applied to the piston.

When the piston pusher goes up, the blade opens. When the piston pushrod is lowered, the blade begins to close towards an object, such as the roof of a car, and cuts it open.

It can be cut by placing it on the working jaws of the hydraulic shears.

The hydraulic shears use hydraulic technology, and the jaw pressure is dozens of times greater than the human force, and of course it is easy to cut.

The hydraulic tong is made by using the principle of lever labor-saving and the law of pressure transmission in the liquid, "the pressure in all parts of the liquid is equal".

The basic working principle of the hydraulic clamp is shown in the schematic diagram:

The handle lifts and depresses to make the small piston reciprocate back and forth.

When the small piston moves upwards, a vacuum is formed in the lower space. The hydraulic oil opens the suction valve under atmospheric pressure and enters the lower space of the piston.

When the small piston moves downward, the hydraulic oil pressure in the lower space increases. This pressure causes the suction valve to close and the discharge valve to open. Hydraulic oil enters the space to the right of the large piston. Push the big piston to move to the left.

The movement of the large piston causes the left edge to cut the chain between it and the fixed block, disconnecting it.

First of all, the distance between the operating handle and the fulcrum is much larger than the distance between the small piston and the fulcrum, so a small force can be generated on the small piston with a small force at the handle.

Thirdly, the force on the small piston is transmitted to the large piston by the hydraulic oil at the same pressure, because the working cross-sectional area of the large piston is much larger than that of the small piston, therefore, a greater driving force is generated on the large piston. Makes the shear force greater.

This is how hydraulic pliers can cut chains.

There is always a way to crack man-made things, even if it can resist hydraulic reinforcement scissors, it can also be opened by other methods, any lock has weaknesses, Yuema's lock is better than the lock made by the general miscellaneous small factory, but it is also relatively expensive. The old thief can get you open no matter what Yuema Seahorse you use, the best anti-theft is to put a few more locks in a guarded place, and don't park it in a remote and dark place at night, this is the foundation of anti-theft, and the lock is just an auxiliary anti-gentleman who does not let the villain go. What can I do if I buy a 100-yuan rechargeable drill Yuema lock?

Have a great day!

Personally, I think it depends on what kind of hydraulic scissors.

The hydraulic shears used by the fire brigade are estimated to be irresistible.

My Suzuki Junwei GSX bought a U-shaped anti-shear anti-theft lock "Dog King RE2200K" The store has this description: I don't know what other motorcycle friends think of thieves nowadays will not bring a huge hydraulic cutter out in the middle of the night.

There are no locks that are resistant to hydraulic shears, only locks that cannot be cut. Another point is that the shears are not very large. But the power is absolutely huge.

There are 16 18 20 tons of force. You say there's something else that can't be cut. However, the caliber of the hydraulic shears is not very large.

Some locks are shear-resistant. That is, ordinary hydraulic shears of several hundred yuan. The cut can't get in.

As long as it is a cut, it can be snapped in. That didn't cut the locks constantly. But so.

More than 1,000 hydraulic shears can cut any lock. Ha ha. So, it's best to install a circuit and vibration alarm for your car.

That is, as long as others cut the thread, they will sound desperately. Plus, as soon as your car rings, your remote control will vibrate. Another point is that there are 240 GPS locators sold online.

He stole your car, and you caught it right away.

The anti-hydraulic shears are just talking, ask the boss to cut it for you, see it, cut the nineteenmm steel bar hydraulic shears You go online to find it, it's not that big, but the thief doesn't need to steal something, just bring a lot of money hydraulic shears and not break through the empty door, so the U-shaped lock looks stout just buy it doesn't have to be expensive.

Usually thieves are armed with a hammer to find a thin U-shaped lock, and when you knock on the U-shaped lock, it will be opened, of course, the lock two must be more visually stunning than one.

Thieves generally use 12t scissors because 16t scissors are inconvenient to carry. There is also between the hydraulic shears and the lock, not only the tonnage, but also the material, that is, the hardness of the lock rod and the hardness of the hydraulic scissor head. For example, the thief has a pair of scissors with a cut head made of diamond, and the scissors body is also the best alloy material, so he can cut any lock.

This is a spear-shield relationship. In fact, the most feasible way is to buy a lock with a chain diameter greater than 20mm. Thieves can't cut it, because the largest hydraulic shears have an opening of only 20mm.

Assuming you are a thief, go to ** and see if it is good to cut 16 tons or 12 tons.

All car locks are given in vain when they encounter hydraulic shears, the hydraulic force can be very large, the shear force is very high, and a metal rod cannot be anti-theft at all.

The lock has always been anti-gentleman, not against villains, and not against thieves.

It is recommended to find a place to park, the lock is useless, it can't be cut, and it is carried away directly.

Resistant to hydraulic shear motorcycle locks are just more resistant to hydraulic shear than ordinary locks, and cannot completely resist hydraulic shear.

The general anti-hydraulic shear lock is that the lock beam cannot be put into hydraulic shear, and the hydraulic shear cannot start the lock. Hydraulic shears usually have an aluminum alloy shell, and the blades are forged from hot-rolled steel.

The piston and its actuator are usually made of hot-rolled alloy steel. Hydraulic shears are mainly used to cut materials such as sheet metal and plastic. Therefore, the hydraulic shear resistant motorcycle lock is mainly focused on the process of increasing the hardness and limiting the hydraulic shear operation.

Hydraulic scissors are devices that use hydraulic oil as the working medium to transmit torque to produce huge shear force on the cutting surface, and there is a distinction between manual and electric. There are also many kinds of hydraulic pliers, just like weightlifting competitions, some can lift 200 pounds, some can lift 300 pounds, if the thief really looks at your motorcycle, then the lock is useless.

Brothers! What locks do you use on your motorcycles? 7kbv0bph

At most, the hardness of the lock is greater.

Since ancient times, locks have been locks for gentlemen and not for villains.

So don't be superstitious about how strong the lock is, think about how you can not let the thief worry about it, if you are remembered, no matter how strong the lock is, it is useless.

There are many kinds of hydraulic pliers, just like a weightlifting competition, some can lift 200 pounds, some can lift 300 pounds... The one above said very clearly, if the thief really takes a fancy to your motorcycle, then what is the use of the lock (when people are thieves, few people will carry it away?) ）

The anti-hydraulic shears are just talking, ask the boss to cut the nineteenmm steel bar hydraulic shears for seeing, you can search the Internet It's not that big, but the thief doesn't need to steal something, just bring a lot of money hydraulic shears and not break into the empty door, so the U-shaped lock looks stout just don't have to be expensive.

Usually thieves are armed with a hammer to find a thin U-shaped lock, and when you knock on the U-shaped lock, it will be opened, of course, the lock two must be more visually stunning than one.

, what's not going to break? Also resistant to hydraulic shears. Everything is relative, and nothing is never broken.

From the lock aspect, it is said that it is very safe, it depends on whether the person who steals uses other violent methods, forcibly tows away, unloads the wheel or something, the lock is best to lock the rear wheel, you lock the front wheel, the person who steals brings a wheel himself, unloads your front wheel, loads his, and rides away. It is recommended to park in a supervised place, the locks are all floating clouds!
