Embodiment 1

[0044] This embodiment provides a foldable comprehensive protection shield, which can ensure that the protection against flames and explosion shock waves is increased on the premise of meeting the traditional bullet protection requirements, and it occupies less space when idle and is convenient to carry.

[0045] like figure 1 As shown, the protective shield includes: soft cloth and more than one folding unit 15; the protective shield in this example includes two folding units 15, and each folding unit 15 includes seven protective panels, thus, the protective shield consists of ten The four protective plates are formed after being sewed and wrapped inside the soft cloth, and there are gaps between adjacent protective plates. The protective shield can be folded and stored along the gap between the adjacent protective plates.

[0046] Specifically: in order to facilitate folding, and to ensure that the folded protective shield has a small area and is easy to carry, fourteen isos...

Embodiment 2

[0055] On the basis of the above-mentioned Embodiment 1, reinforcement protection is carried out at the crease of the protective shield, and at the same time, it is ensured that the reinforcement protection does not affect the folding of the protective shield; The "meter"-shaped connection of the joint is reinforced by the cross-shaped protective plate 16; such as image 3 As shown in the figure, when the protective shield has two folding units, there are three “m”-shaped joints, which are the opposite right-angle vertices of the triangular plate M7 and the triangular plate G8, the opposite right-angle vertices of the triangular plate D4 and the triangular plate E5, and the triangular plate H9 Opposite to the right-angle vertex of the triangular plate N10; a cross-shaped protective plate 16 (material is aerogel felt and aramid fiber braid or UHMWPE fiber braid) is set at each "meter"-shaped connection, and the cross-shaped protective plate 16 There is a rectangular protective ...

Embodiment 3

[0058] The difference from Embodiment 1 above is that the foldable comprehensive protective shield provided in this embodiment directly uses a flexible protective layer as the protective body of the protective shield, and then arranges multiple pieces on one surface or two opposite side surfaces of the flexible protective layer. The rigid support plates structurally support the flexible protective layer; there are gaps between adjacent rigid support plates as crease, so that the protective shield can be folded along the crease and then stored. Among them, the hard support material is aerogel felt and UHMWPE fiberboard, and the material of the flexible protective layer is aerogel felt and bulletproof fiber.

[0059] That is, the protective shield in this embodiment includes: a flexible protective layer and four folding units, two folding units are arranged on two opposite side surfaces of the flexible protective layer, and the folding units on both sides are symmetrically arrang...

Abstract

The invention discloses a folding comprehensive protection shield which can meet the bullet protection requirement and solve the problems that an existing bulletproof shield is small in protection area, heavy, inconvenient to carry and incapable of achieving comprehensive protection. The folding shield comprises soft cloth and one or more folding units; each folding unit comprises multiple protection plates, the protection plates are integrated into a whole through the soft cloth, and creases are formed through gaps of the hard protection plates, so that the hard bulletproof plates can be folded along the creases; each protection plate is of a multi-layer composite structure, aerogel felt can isolate heat and avoid thermal burns such as gasoline bombs and the like, the bulletproof layer can prevent fragment killing generated by explosion, and the top structure can avoid shock wave diffraction. The comprehensive protection shield can provide top protection and prevent shooting by peopleat high positions; and meanwhile, the top protection structure can prevent shock waves from diffracting to kill people behind the protection shield.

Description

technical field [0001] The invention relates to a comprehensive protective shield, in particular to a foldable comprehensive protective shield, which belongs to the technical field of protective equipment. Background technique [0002] The shield is a kind of hand-held protective equipment to protect the human body from harm. It is used as a police device in the police and riot troops all over the world. Personal safety. [0003] At present, domestic traditional bulletproof shields are generally hand-held or wheeled. Hand-held bulletproof shields can only provide protection for one person; wheeled bulletproof shields are bulky and inconvenient to carry. Based on the above reasons, police officers may not be able to provide coordinated protection or emergency response to special security situations when performing their tasks. [0004] At present, traditional domestic shields generally only provide bulletproof function. Because traditional bulletproof shields are basically...
