This steel plate has been specially treated to have extremely high impact resistance and ballistic resistance. Bulletproof steel plate is widely used in the military, police, security and other fields to manufacture bulletproof vests, bulletproof helmets, bulletproof vehicles, etc.
[0003] The bulletproof plates currently on the market are difficult to penetrate when shot, but they can still be deformed, causing bulges in the internal structure and affecting the equipment installed on them. Utility Model Content
[0004] The utility model aims to provide a bulletproof plate with good anti-deformation performance, which solves the existing problems.
[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0006] The utility model is a bulletproof plate with good anti-deformation performance, comprising an intermediate layer, wherein the top and the bottom of the intermediate layer are both provided with honeycomb panels, and one end of two honeycomb panels away from the intermediate layer is provided with outer layers, and four buffer mechanisms are provided at the bottom of one of the outer layers.
[0007] Furthermore, the material of the middle layer is PP material, and the middle layer of PP material has good oil resistance, weak acid and alkali resistance and high temperature resistance.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figure 1-4 The utility model is a bulletproof plate with good anti-deformation performance, including an intermediate layer 1, the top and bottom of the intermediate layer 1 are both provided with honeycomb panels 2, the ends of the two honeycomb panels 2 away from the intermediate layer 1 are both provided with outer layers 3, and the bottom of one of the outer layers 3 is provided with four buffer mechanisms 4.
[0025] The material of the middle layer 1 is PP material, and the middle layer 1 made of PP material has good oil resistance, weak acid and alkali resistance and high temperature resistance.
[0026] The two outer layers 3 are both made of PMI material. The outer layer 3 made of PMI material has the characteristics of light weight, high strength and closed-cell structure.
[0027] The two honeycomb panels 2 are both made of aluminum. The aluminum honeycomb panels 2 have excellent strength and stability, can reduce deformation, and can absorb vibration.
[0028] The buffer mechanism 4 includes a buffer spring 41, one end of which is fixedly connected to the bottom of one of the outer layers 3, and the other end of the buffer spring 41 is fixedly connected to a mounting plate 42, and a slide cylinder 43 is fixedly connected to the top of the mounting plate 42, and a speed bump 44 is fixedly connected to the inner wall of the slide cylinder 43, and a slide rod 45 is passed through and slidably connected to the top of the slide cylinder 43, and the top of the slide rod 45 is fixedly connected to the outer layer 3, and the bottom of the slide rod 45 is fixedly connected to a slider 46, and a contact rod 47 is hinged on the side of the slider 46, and an elastic rope 48 is fixedly connected to the bottom of the contact rod 47, and the end of the elastic rope 48 away from the contact rod 47 is fixedly connected to the side of the slider 46.
[0029] The length of the contact rod 47 is greater than the distance from the surface of the slider 46 to the speed bump 44. The speed bump 44 is made of rubber. When the contact rod 47 moves with the slider 46, it will contact the speed bump 44. When the contact rod 47 is squeezed with the rubber speed bump 44, a large resistance will be generated.
[0030] A specific application of this embodiment is: the whole bulletproof plate is installed in a suitable position, and the equipment can be installed thereon. The whole bulletproof plate is formed by a middle layer 1 of PP material, two outer layers 3 of PMI material and two honeycomb panels 2 of aluminum material through high temperature and high pressure gluing, so that the bulletproof plate can reduce deformation and absorb vibration when it is shot, and further improve the bulletproof performance. When the bulletproof plate is impacted by a gunshot, part of the impact force may be transmitted to the bottom. At this time, the bulletproof plate and the slide bar 45 will move downward, the buffer spring 41 absorbs the impact force and tightens, and the slide bar 45 moves downward. The movement will drive the contact rod 47 to move downward and contact the speed bump 44. At this time, the contact rod 47 will be deflected and will not produce too much resistance to affect the buffer spring 41 to absorb the impact force. Then the elastic rope 48 drives the contact rod 47 to restore. When the buffer spring 41 rebounds and drives the bulletproof plate and the sliding rod 45 to move upward to restore, the contact rod 47 moves upward and contacts the speed bump 44. At this time, the contact rod 47 cannot be deflected and will be squeezed with the rubber speed bump 44 to produce greater resistance to reduce the rebound amplitude of the buffer spring 41, thereby reducing shock, and further reducing the impact of the bulletproof plate on its installation after being shot.
