Anti-tamper bolt structure of safety box

Abstract

The invention relates to an anti-tamper bolt structure of a safety box. The structure comprises a door frame (1), and a door plate (2) arranged in the door frame (1), and is characterized in that: the back surface of the door plate (2) is provided with a clasp ring bolt (3) which only can rotate around the axis of the clasp ring bolt (3); the clasp ring bolt (3) is in an opening annular shape and provided with a notch (31); the door frame (1) is provided with an inwardly bent inside wall (11); the inside wall (11) is provided with a first bolt hole (111) and a second bolt hole (112) for the clasp ring bolt (3) to penetrate and pass through respectively; and the back surface of the door plate (2) is provided with a driving structure for driving the clasp ring bolt (3) to rotate. In a door closing state, the clasp ring bolt penetrates the first bolt hole, passes through the second bolt hole, and completely clasps the inside wall of the door frame, so that locking area is greatly increased, the clasp ring bolt or the inside wall on the front door frame is needed to be pried off if the safety box is needed to be broken, and the function of completely clasping and locking the inside wall on the door frame is added; therefore, the anti-theft performance of the safety box is further enhanced.

Description

Anti-tamper latch structure for safe technical field The invention relates to a tamper-proof door latch structure suitable for a safe. Background technique The door bolt structure of the existing safe box includes a slide plate arranged on the back of the door plate that can slide relatively laterally. The front end of the slide plate is connected with a bolt head. Among them, there are many types of lock structures, and various existing structures can be used. When locking, the latch head is inserted into the latch hole on the door frame, and then the lock structure is used to lock the slide plate, so that the latch head cannot withdraw from the door frame hole, so as not to be opened by others. The purpose of the latch head is generally cylindrical, and the latch hole is a cylindrical hole matching the shape of the latch head. And there are some defects in this safety door, if what criminals pry is not the lock, but the door frame, because there is no any obstruction st...

AI Technical Summary

Problems solved by technology

There is one thing in common in the above various tamper-resistant door latch structures. The latch head only protrudes from the hook portion or the protruding shaft of the peripheral wall of the latch head and the side wall of the door frame hole. Small, the anti-hook strength is not enough; in addition, when locking, the bolt head needs to rotate around its own axis to achieve the anti-hook effect. Therefore, the driving structure of the door bolt is relatively complicated. There is a matching structure between the bolt head and the screw guide sleeve. In order to achieve the purpose of the bolt head rotating around its axis
