Embodiment Construction

[0012] The relocking device of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, the relocking device of the present invention includes a steel wire rope 2 , a fixed-load fixed pin 1 , a fixed-load nylon ring 3 , a pre-tension spring 4 and a bolt head 5 . The steel wire rope 2 is arranged in a mesh shape at half the thickness of the door panel, and each mesh node 21 is provided with a fixed-load fixing pin 1 (only a broken line is required to achieve the wire rope when the fixed-load fixing pin breaks). The purpose of loosening; the use of mesh arrangement is to make the distribution of wire ropes more dense, so that any position of the vault door can be loosened by external force, which is the best solution), and the wire rope 2 is tightened through the fixed load pin 1. One end of the steel wire rope 2 is looped on a fixed-load fixed pin 1 to realize end point fixation, and the othe...

Abstract

The invention discloses a breakage-proof relocking device for a vault door. The vault door comprises a door plate, a sliding bolt plate and a door plate fixing seat, the sliding bolt plate is slidably arranged below the door plate fixing seat, and a circular hole is arranged on the sliding bolt plate. The relocking device comprises a constant-load nylon ring and a bolt head, the upper end of the constant-load nylon ring is fixed into the door plate, the bolt head is connected with the lower end of the constant-load nylon ring and is positioned right above the circular hole of the sliding bolt plate, and a pre-tightening spring is arranged above the bolt head. The breakage-proof relocking device for the vault door is simple in structure, and can effectively guard against theft as the vault door can be relocked under the action of external force such as thump or high temperature.

Description

technical field [0001] The invention relates to an anti-destructive relocking device for a vault door, in particular to a device for relocking the vault door when it is damaged by external force (including heavy impact and high temperature).
