When buying a cam lock, many people will ask if the cam lock is difficult to open, should I add some oil?
In fact, it is not used. The cam lock is different from the door locks used in daily life. The structure of the cam lock is relatively simple, but every time the door lock encounters the key inserted into the door lock, it is difficult to turn the key. People will put some oil into the keyhole of the door lock. In fact, the door lock is difficult to open, just put a pencil end to solve it, do not refuel. Because every lock cylinder is maintained with lubricating oil when it leaves the factory, there is no need to add oil to the keyhole. Therefore, it is very difficult for the cam lock to encounter the problem that is difficult to twist like a door lock.
What is the structure of the cam lock?
The cam locks seen in daily life generally consist of a bolt, a lock body, a nut, a screw and a key (as shown in the figure below).
The following pictures are introduced in turn: The first is the lock body. The wellhw cam lock is made of zinc alloy and is integrally die-cast. The entire lock body is made of precision-cast solid lock body, which mainly plays a role of waterproof, rust-proof, strong and durable. The thread details of the lock body are changed to deepen the thread, and the installation texture is good; the second is the circlip, which mainly prevents the lock body from shaking, which damages the product itself and improves the service life of the tongue; the third is the fixed roller ring, wellhw The use of delicate and thick fixed ring prevents the cam lock from loosening when used after installation; the fourth is the 90-degree limit circlip; the fifth is the lock plate, the lock plate is the best part of the whole cam, which is the cam of many merchants The lock piece of the lock is easy to break. After the team’s experiment and discussion, wellhw has improved the lock piece, thickened, smooth, firm and anti-theft; the sixth is the embossed screw, which is simple and easy to use. Tighten and not loose; finally speaking of the key, the key used in the cam lock is double-toothed, with anti-theft function, generally can prevent technical methods to open, and prevent the master key from opening
