Self-buckling type slide anti-theft lock with anti-push pressure and pick-proof functions

Abstract

The invention discloses a clinching type sliding antitheft lock with anti-bulldozing and anti-prying functions, comprising a key, a lock shell and a lock plunger, wherein, the lock shell is provided with a lock plunger hole for the lock plunger to pass through, the lock shell consists of a base and a lock sleeve which are connected mutually, a cavity is formed between the base and the lock sleeve and internally provided with a lock core, a spring, a film threading and a lock plunger shrapnel, the mounting positions of the spring and the shrapnel are matched with the position of the lock core, and the lock shell is provided with an anti-bulldozing and anti-prying mechanism. The antitheft lock is provided with the anti-bulldozing and anti-prying mechanism, thus avoiding the generation of malposition clearance between door plates when external force is applied on the door plate of a horizontal sliding door, preventing the front and back movement of the door plate in opposite directions, eliminating the safety hazard that objects in the horizontal sliding door can be stolen and effectively improving the safe coefficient when the antitheft lock is used.

Description

technical field [0001] The invention relates to an anti-theft lock, in particular to a self-buckle sliding type anti-theft lock used on a sliding sliding door. Background technique [0002] Sliding sliding doors are an important part of display cabinets such as exhibition cabinets at present. They are composed of left door panels 100 and right door panels 200 arranged in pairs. By pushing the door panels, it is convenient to take and place objects in the cabinet. The door is equipped with a self-locking sliding type anti-theft lock for anti-theft. [0003] The structure of the traditional sliding sliding door anti-theft lock is as follows: Figure 1 to Figure 3 As shown, it includes a key 1, a lock case and a lock bolt 6. The lock bolt 6 has row-type ratchet teeth. The lock case has a lock bolt hole 2c for the lock bolt 6 to pass through. 5 and the lock sleeve 2, a cavity is formed between the two, and the lock core 3, the spring 8, the insert 9 and the lock bolt shrapnel 4...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned anti-theft lock has a certain anti-theft effect, its shortcoming is that when the left door panel 100 or the right door panel 200 is pushed by external force, since the door panel and the anti-theft lock do not possess the anti-push function, the right door panel 200 will be locked in place. Moving backwards in the front-to-back direction, a dislocation gap is easily formed between the two door panels. When the gap is enough to accommodate the entire anti-theft lock, when the left door panel 100 or the right door panel 200 is pushed to the left or right, the left door panel 100 or the right door panel 200 can be left. The door panel 100 or the right door panel 200 moves in the left and right directions, thereby stealing the items in the sliding door exhibition cabinet, resulting in the loss of the items. Therefore, the anti-theft lock in the prior art has potential safety hazards, and its anti-theft performance needs to be further improved.
