Multifunctional anti-cracking echelette grating

Abstract

The invention discloses a multifunctional anti-cracking echelette grating. A circuit board is fixed to a pipe rod plug through a screw, a plug-in type connector socket is welded to the tail end of the circuit board, an outer protection shell is buckled with a buckle hole of a base through buckle teeth, the two sides of the lower portion in the outer protection shell are connected with linkage grabbers through screws, and barbs are arranged at the front ends of the linkage grabbers. The linkage grabber is in linkage connection with the inner protective shell, when the outer protective shell slides into the base for buckling connection, the barb at the front end of the linkage grabber is located at the position of the barb groove of the inner protective shell and hooks the rear protruding ring of the inner protective shell, and when the outer protective shell is separated from the base, the barb of the linkage grabber can pull out the hooked inner protective shell together in a linkage mode. The pulled-out inner protective shell also can be linked to extrude out the plug-in type wiring plug together to be separated from the plug-in type wiring socket. According to the optical grating, various cracking prevention functions such as shell disassembly prevention, riot disassembly prevention, rod moving prevention and technical solution prevention are achieved, the functions of rainwater prevention, floating dust prevention, insect and ant prevention, external wiring and the like are further achieved, and new development of optical grating products is innovated.

Description

technical field [0001] The invention relates to the field of security equipment, in particular to a multifunctional anti-cracking infrared grating. Background technique [0002] The existing infrared grating is a security protection product that utilizes the principle of active infrared detection and plays the role of alarming when the thief blocks the infrared rays. In practical applications, grating products are mostly used in the perimeter protection of security systems, that is, deployed on the outermost layer of the protected area, such as doors, windows, gardens, walls, etc. For high-value protection targets, thieves will also work hard on how to crack security products, which of course includes cracking optical grating products. By analyzing and summarizing the case site and industry information, the applicant concluded that there are generally two hidden dangers in the design of grating products currently on the market: [0003] One is that the existing grating pro...

AI Technical Summary

Problems solved by technology

[0003] One is that the existing grating products, without exception, can be disassembled and taken away without immediate alarm. The wiring and fastening structure inside will be exposed to varying degrees, which provides the possibility of cracking. This is a serious security risk

[0004] The second is that the technical protection capabilities of existing grating products are uneven. Some of the key circuits are exposed after the shell is disassembled, and no good protection measures are provided; some only rely on the mechanical structure to provide anti-gentlemen's protection; Insufficient protection, so that the grating is easy to be moved and cracked; some only rely on a single tamper switch for protection, which is too thin
