Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
As shown in fig. 1-3, the novel protection unit structure provided by the invention comprises a stab-resistant sheet body 1;
the stab-resistant sheet body 1 comprises a plurality of unit layers 11, and at least three layers of the unit layers 11 are arranged;
the plurality of unit layers 11 are mutually pressed, bonded or integrally formed;
the plurality of unit layers 11 are translated at equal intervals along the linear direction so as to form stepped lapping parts 11 on the edge of the stab-resistant sheet body 1;
the adjacent stab-resistant sheet bodies 1 are lapped into a whole through the stepped lapping part 11.
In an alternative embodiment, the body 1 of the stab-resistant sheet has a thickness of 4 mm.
In the invention, a plurality of unit layers 11 are mutually pressed, bonded or integrally formed to form the stab-resistant sheet body 1; the edge of the stab-resistant sheet body 1 forms a stepped lapping part 11; the adjacent stab-resistant sheet bodies 1 are lapped into a whole through the stepped lapping part 11. The stab-resistant sheet body 1 formed in this way can effectively prevent attacks of oblique stabs. When receiving the attack of oblique thorn, after sharp thing broke through the first layer protective structure of stairstepping overlap joint portion 11, hardly broke through the second floor structure of stairstepping overlap joint portion 11, and stairstepping overlap joint portion 11 inboard has third layer or even more layer structures to protect and prevent thorn piece body 1 and not destroyed to protection life safety. The multilayer of the stab-resistant sheet body 1 forms a stepped lapping part 11 structure, so that not only can vertical attack be prevented, but also oblique stab attack can be effectively prevented, the safety factor is increased, and the safety of a user is ensured.
