Embodiment 1

[0044] This embodiment provides a foldable comprehensive protective shield, which can increase the protection of flames and explosion shock waves under the premise of meeting the traditional bullet protection requirements, and takes up less space when it is idle, and is easy to carry.

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

[0046] The details are: in order to facilitate folding, and to ensure that the folded protective shield has a small area and is easy to carry, fourteen isosceles right-angled triangle protecti...

Embodiment 2

[0055] On the basis of the above-mentioned embodiment 1, the reinforcement protection is carried out at the crease of the protective shield, and at the same time, it is ensured that the reinforcement protection carried out does not affect the folding of the protective shield; The "m"-shaped joints are reinforced by cross-shaped protective plates 16; image 3 As shown, when the protective shield has two folding units, there are three "meter"-shaped joints, which are respectively the opposite right-angled vertices of the triangular plate M7 and triangular plate G8, the opposite right-angled vertices of the triangular plate D4 and triangular plate E5, and the opposite right-angled vertices of the triangular plate H9 Opposite to the right-angle vertex of the triangular plate N10; a cross-shaped protective plate 16 (made of airgel felt and aramid fiber braid or UHMWPE fiber braided fabric) is arranged at each “meter”-shaped connection, and the cross-shaped protective plate 16 It ha...

Embodiment 3

[0058] The difference from the above-mentioned embodiment 1 is that the foldable comprehensive protective shield provided in this embodiment directly adopts the flexible protective layer as the protective body of the protective shield, and then arranges multiple pieces on one side surface or two opposite side surfaces of the flexible protective layer. The hard support boards provide structural support for the flexible protective layer; there are gaps between adjacent hard support boards as creases, so that the protective shield can be folded along the creases and then stored. Among them, airgel felt and UHMWPE fiberboard are used as the hard support material, and airgel felt and bulletproof fiber are used as the material of the flexible protective layer.

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

Abstract

The invention discloses a foldable comprehensive protective shield, which can solve the problems of the existing bulletproof shields such as small protective area, bulky bulletproof shield, inconvenient carrying and incapable of comprehensive protection while meeting bullet protection requirements. The folding shield includes: soft cloth and more than one folding unit; each folding unit includes a plurality of protective plates, the protective plates are integrated into a whole through the soft cloth, and creases are formed through the gaps of the hard protective plates to make the hard bulletproof plate It can be folded along the crease; the protective plate is a multi-layer composite structure, in which the airgel felt can insulate heat and avoid thermal burns such as petrol bombs, the bulletproof layer can block the fragments caused by the explosion, and the top structure can avoid shock wave diffraction. Moreover, the comprehensive protective shield can provide top protection to avoid being shot by people at high places; at the same time, the top protective structure can prevent shock wave diffraction from killing people behind the protective 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] A shield is a hand-held protective equipment that protects the human body from harm. It is used as a police device in police and anti-riot forces around the world. It is mainly used to defend against mob stones, sticks and bullets, and to protect police officers. Personal safety. [0003] At present, domestic traditional bulletproof shields are generally hand-held or wheeled. Hand-held bulletproof shields can only provide one-person protection; 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 be unable to respond to special security situations when performing their tasks. [0004] At present, traditional domestic shields generall...
