Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Examples

As shown in fig. 2, an encryption gunshot pad of shock attenuation resistance to compression, including shock-resistant layer 10, buffer layer 20 and the basic unit 30 that from top to bottom sets gradually, buffer layer 20 and basic unit 30 cladding are in the inside of shock-resistant layer 10, be equipped with buffering clearance 40 between shock-resistant layer 10 and the buffer layer 20, shock-resistant layer 10 is chloroprene rubber, buffer layer 20 is polyurethane, basic unit 30 is polymethyl methacrylate.

Conventional shock pads are made of a single material, either soft or hard, and only provide a cushioning condition when a projectile is struck thereon. The soft material can generate serious deformation each time the soft material contacts a shooting ball, so that the ageing deformation and even breakage of the soft material are accelerated; the rigid material has high rigidity, and the deformation of the shot bullet in each contact is not obvious, so that the force unloading effect on the shot bullet is not good, and the shot bullet is easy to rebound at high speed. The utility model adopts a three-layer composite structure, the outmost layer adopts chloroprene rubber as an impact resistance layer 10, chloroprene rubber has hardness and elasticity, is usually used as a sealing washer, has strong impact resistance, directly blocks the speed limit to shooting bullets after contacting the shooting bullets, simultaneously, because of the existence of a buffer gap 40, the impact resistance layer 10 can be sunken inwards until contacting with a buffer layer 20 due to the characteristic of rubber, the buffer layer 20 is polyurethane, which is PU foaming material, the elasticity is very strong, the shooting bullets decelerated by the impact resistance layer 10 can continue to impact and compress the buffer layer 20, the buffer layer 20 carries out secondary deceleration buffering to the shooting bullets through deformation, simultaneously, because the external impact resistance layer 10 has the protective effect to the shooting bullets, the buffer layer 20 is prevented from being damaged to the maximum extent, the base layer 30 is polymethyl methacrylate, also known as organic glass, the shock resistance and the rigidity are large, the mounting structure is used for mounting the substrate, and the firmness of the whole gunshot pad mounting structure is ensured.

Further, as shown in fig. 1 and 2, bosses 11 are provided on the upper surface of the impact-resistant layer 10, and the bosses 11 are uniformly distributed on the upper surface of the impact-resistant layer 10. The side of the boss 11 is an inclined plane, and the included angle between the side of the boss and the upper surface of the impact resistance layer 10 is an obtuse angle, so that when a shooting ball is shot on the side of the boss 11, the impact force of the shooting ball can be decomposed into a vertical direction and a horizontal direction, pre-unloading force is exerted on the shooting ball, and the impact of the shooting ball on the surface of the impact resistance layer 10 is reduced.

Further, as shown in fig. 2, a first buffer ball 12 is disposed on a lower surface of the impact resistant layer 10, a second buffer ball 21 is disposed on an upper surface of the buffer layer 20, and both the first buffer ball 12 and the second buffer ball 21 are disposed in the buffer gap 40. When the impact layer 10 is compressed by the impact of the firing bomb, the impact layer 10 is bent and deformed, the first buffer balls 12 are in contact with the second buffer balls 21, and are mutually extruded to fill the gaps between the first buffer balls and the second buffer balls, so that a gradual change process is formed in the buffer process of the impact layer 10, and the impact layer 10 and the buffer layer 20 are protected to the greatest extent.

Further, as shown in fig. 2, the first buffer ball 12 and the second buffer ball 21 are both hemispheres, and the first buffer ball 12 and the second buffer ball 21 are distributed in a non-equidistant manner, that is, the distances between the first buffer ball 12 and the adjacent second buffer ball 21 are different. When the first buffer ball 12 moves towards the second buffer ball 21, the first contacted second buffer ball 21 can generate extrusion and repulsion force to the first buffer ball 12, and extrude and repel the first buffer ball towards the gap, so that the impact-resistant layer 10 generates lateral cheapness, and lateral friction force is formed between the impact-resistant layer 10 and the bullet head of the shooting bullet, so that the shooting bullet is inclined, and the bullet can be prevented from directly rebounding to hurt people.

Further, as shown in fig. 1, four sides of the substrate 30 are provided with protruding plugs 31 and plug holes 32 disposed adjacent to the plugs 31. The condition that local not hard up droing appears easily in single piece installation of gunshot pad, through setting up bayonet 31 and spliced eye 32 cooperation, make adjacent gunshot pad mutual fixed connection, improve the fastness of whole gunshot pad installation, reduce local prosthetic number of times and cost.
