Modular multifunctional combined type folding bulletproof shield
Technical Field
The utility model belongs to the technical field of folding shellproof shield, concretely relates to shellproof shield is folded to many function combination of modularization formula.
Background
The bulletproof shield is used as a police individual protection device and is mainly used for protecting a human body from being penetrated by bullets or fragments, and the effect of protecting the life safety of the human body is achieved. In the standard of the Chinese public safety industry, the bulletproof shields are divided into a handheld type and a wheel type according to the product structure, and products in domestic markets are basically guided by the industry standard, so that bulletproof shields with other structures rarely appear. The hand-held type is wide and single in function, generally uses GA3 grade bulletproof shields (medium shields) as the main parts, the shield quality of the protection grade is light, the shield can be held by one hand for shielding, the other hand holds the curved arm of the pistol to bypass the shield for aiming and shooting, and the bullet-proof shields used by special polices have more opportunities. However, when the bullet-proof shield (heavy shield) with the grade of GA5 or more is used, the total mass of the bullet-proof shield is much higher than that of the medium shield, and the bullet-proof shield is too heavy and can only be held by two hands or pushed and pulled by a motor wheel, so that the bullet-proof shield is inconvenient to carry under the condition of battle transfer in a complex terrain. Wheel type shields in the market mostly mainly adopt a single integral protection plate, have large weight and volume, and are mainly inconvenient to carry and not strong in universality.
Whereas the existing folding shields just solve this problem. At present, the folding shields on the market mainly have the following types:
the first folding shield, as disclosed in patent document CN109923369A, is a light and foldable soft anti-riot shield developed abroad to solve the problem of heavy burden on anti-riot police, and is mainly composed of a continuous sheet and a hinge as a whole. The weight of the shield is about 25kg, the shield can be unfolded through a hinge when in use, 12 layers of bulletproof Kevlar are particularly added at the interlayer of the shield, the shield can resist 9mm, 357Magnum and 44Magnum bullet shooting, the protection grade is not high, and in addition, the shield is formed into a whole and cannot be disassembled in a modularized mode.
The second type of bats folding bulletproof shield, as disclosed in patent documents CN202032945U and CN107615003A, is made by folding a left shield, a middle shield and a right shield in a butterfly shape by hinges and elastic fasteners, and can defend police class 3.
The third type of folding bulletproof shield is formed by connecting a plurality of plates by a hinge structure and then laminating the plates into a whole, for example, CN107192300B, can be formed by pressing PE material and can protect AK.
Although the folding shield solves the problems of inconvenient carrying and incapability of quick transfer, the folding shield in the prior art has single protection index and weak modularization, and the shield body splicing unit is limited by shape, size and fixed assembly and cannot be converted or replaced by other products for use. Meanwhile, if a local shield body is damaged, the whole shield body armor needs to be replaced due to the non-standard modular unit, so that the rapid repairability is poor, and the maintenance cost is high.
