The combination of the deadbolt
The combination of the deadbolt introduce.
It is mainly composed of large support body, small support body, pull tab and brake pad and other parts.
Large support body: The main function of the large support body is to drive the rotation of the large lock tongue. Its head is linked with the large lock tongue, and a rectangular hole in the middle cooperates with the hanging lugs on the pull tab to control the expansion and contraction of the large lock tongue. There is a brake pad slot on the outermost side of the large bracket.
Small support body: The small support body is the main part that controls the self-locking of the large lock tongue. Its head is used to assemble the small lock tongue. Unlike the large support body, the middle of the small support body is a protruding triangle, which can be used to push the brake piece.
Pull tab: When the large lock tongue is retracted, the pull tab makes the large lock tongue no longer protrude, thereby preventing the self-locking of the large lock tongue. The pull tab is inserted into the rectangular hole in the middle of the large support body through the hanging lugs on the top, so that the pull tab and the large support body are retracted inwardly, so as to control the lock tongue. In addition, the support angles on both sides of the pull tab can control the brake pads, thereby releasing the self-locking of the large lock tongue.
Brake pad: The brake pad can play the role of anti-prying, and the self-locking of the large lock tongue is controlled by the brake pad, so that the large lock tongue cannot be easily opened.
