Bulletproof helmet without connector and non-hole connection

Abstract

A bulletproof helmet free of connectors and hole connections is prepared as forming and distributing multi-group connection elements symmetrically to central axis in bulge free mode as per requirement of connection-fastening system at internal wall of casque shell when said shell is formed by nonmetal material, enabling to connect said system to said elements in separated way, using a regulation-fastening belt to connect said shell and said system together to form Y shaped three-way regulation-fastening unit with lower jaw part being able to be regulated dynamically.

Description

technical field [0001] The invention relates to the technical field of helmets, and is a bulletproof protective helmet used by military, police and civilians, in particular a bulletproof helmet without connectors and holes. Background technique [0002] Existing bulletproof protective helmets all are made up of helmet shell, connection fastening system, its connector. Among them, the main function of the helmet shell is to effectively protect the wearer's head safety: bulletproof, anti-collision, anti-penetration, anti-rainwater, etc., and can also be installed with protective masks and other protection, measurement, and communication devices. Helmets are usually made of metallic or non-metallic materials. Metal helmet shells are bulky and prone to ricochet secondary injuries, and are gradually being replaced by non-metallic helmet shells. The non-metallic helmet shell has good bulletproof performance, no secondary injury by ricochets, light weight, comfortable wearing, go...

AI Technical Summary

Problems solved by technology

However, the connection between the suspension device and the helmet shell is flawed: the three-point fixed suspension device is designed to reduce holes and improve the bulletproof effect, and the stability is poor; the chin adjustment and fastening system is more troublesome, so it needs to be improved

However, the stability of the three-point fixed suspension device is relatively poor; the degree of adjustment of the head circumference is small; the chin adjustment and fastening system relies on the heavier connector, lower support, and lower support fastening belt in Figure 3 of this patent: 41, The continuous adjustment of 6, 312, 7, 5 connecting parts can be completed, the connection is not good, so it needs to be improved

[0023] In the above-mentioned four kinds of patents and modern standard helmets, there are connectors that must be blindly aligned and disassembled. Repeated adjustment many times, wearing time-consuming and troublesome, there is also a need for improvement
