Kind Code:
A1
Abstract:
Disclosed in the present invention is a code searching structure applied to a button code lock, comprising a lock base, a lock cylinder, a push rod, a push rod cam and a push rod spring, and several pairs of button springs and code buttons. When a lock is in a locked state, the push rod is static; when the code buttons in any state are pressed down, clamping hooks can hook limit ring grooves to prevent the code buttons from bouncing up; when a code is searched, a key fitted with the lock cylinder is inserted and rotated, and the lock cylinder drives the push rod cam to rotate so as to drive the push rod to move along an axis, so that the clamping hooks are aligned with receding notches; and when the code buttons in different states are pressed down, two results that the clamping hooks are hooked and cannot be hooked are generated, and the correct code is found according to different results. In the present invention, when a user forgets the code, the user only needs to use the key to rotate the lock cylinder and press down the code buttons one by one, having simple operation, having high efficiency, being unnecessary for disassembling the button code lock, and having good user experience.
