Abstract

The invention relates to a fork-shaped sheet top locking lock core. The fork-shaped sheet top locking lock core comprises an outer sleeve and a cylindrical core body, wherein a cylindrical through hole is formed in the outer sleeve; the core body is arranged in the outer sleeve in a matched mode; an axial cylindrical key hole is formed in the core body; a certain number of sheet mounting gaps with matched direction are at least reserved on the core body; a fork-shaped sheet with matched thickness is arranged in each sheet mounting gap; a cross beam is arranged on the upper part of the fork-shaped sheet; vertical legs are arranged on the two sides of the fork-shaped sheet; the cross beam on the upper part of the fork-shaped sheet is placed on the inner edge, corresponding to the sheet mounting gap, of the core body; the cross beam passes through the key hole transversely and is embedded into the key hole with a certain depth; a top pin is arranged on the upper part of the cross beam; aspring and a billiard are arranged on the upper part of the top pin and are positioned in a spring hole in the side wall of the outer sleeve; a sealing head is arranged on the upper end part of the spring; and a rotating notch is reserved on the outer end face of the core body. The fork-shaped sheet top locking lock core can basically avoid the technologically unlocking phenomenon and has high safety.

Description

technical field [0001] The invention relates to the technical field of locks, in particular to a fork-shaped sheet top locking cylinder. Background technique [0002] In the prior art, there are various locks, such as electronic locks, fingerprint locks, and the most common locks are mechanical locks, which are mainly composed of a lock cylinder, a lock head body and a marble installed in the inner track of the lock head. Composed of a spring, the lock cylinder and the lock body can rotate with each other to achieve the purpose of unlocking, and the combination of the pins and springs and the key together form the key to unlocking. The above-mentioned conventional mechanical tumbler locks are easy to achieve the effect of unlocking through technical methods such as stirring or vibration, resulting in poor security of these locks, which is not conducive to anti-theft. Contents of the invention [0003] The object of the present invention is to solve the above problems, and...
