Description

Technical Field

[0001] The utility model belongs to the technical field of bulletproof ceramic sheets, and specifically relates to a multi-curved surface spliced ​​bulletproof ceramic sheet. Background Art

[0002] Bulletproof ceramic sheets, through their unique structure and composition materials, can quickly disperse the energy of bullets or shrapnel to a larger area, thereby reducing the harm to the human body. At the same time, their high hardness and wear resistance enable them to effectively block the penetration of shrapnel or bullets, providing safety protection for the human body.

[0003] Bulletproof vests are generally composed of an inner ceramic bulletproof plate and a fiber material that wraps the ceramic bulletproof plate to increase wearing comfort. The ceramic bulletproof plate is an important component of human body bulletproof vests, and the bulletproof performance of the ceramic bulletproof plate directly determines the performance of human body bulletproof vests.

[0004] The currently popular multi-curved bulletproof ceramic plates are all integrated and cannot be pieced together into one. Moreover, if an integrated bulletproof ceramic plate is accidentally damaged by an impact, it needs to be replaced as a whole. Therefore, replacing the integrated bulletproof ceramic plate as a whole is likely to cause a waste of resources of some bulletproof ceramic sheets.

[0005] In order to solve the above problems, the present application proposes a multi-curved spliced ​​bulletproof ceramic sheet. Utility Model Content

[0006] In view of the problems in the related art, the utility model proposes a multi-curved spliced ​​bulletproof ceramic sheet to overcome the above-mentioned technical problems existing in the existing related art.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A multi-curved spliced ​​bulletproof ceramic sheet comprises an arc-shaped plug plate, a first positioning hole is formed on the outer surface of the arc-shaped plug plate, a second positioning hole is formed on the outer surface of the arc-shaped plug plate, a first fixing block is fixedly connected to the inner surface of the arc-shaped plug plate, the first fixing block is located in the first positioning hole, a special-shaped ceramic sheet is welded to the side of the first fixing block away from the arc-shaped plug plate, a second fixing block is fixedly connected to the inner surface of the arc-shaped plug plate, the second fixing block is located in the second positioning hole, and a rectangular ceramic sheet is welded to the side of the second fixing block away from the arc-shaped plug plate.

[0009] The top of the arc-shaped plug plate is fixedly connected to a load-bearing rod, and a square handle is installed on the top of the load-bearing rod. By arranging the load-bearing rod and the square handle, the wearer can hold the square handle to drive the arc-shaped plug plate to move as a whole through the load-bearing rod, so that the wearer can quickly put on or remove the arc-shaped plug plate as a whole.

[0010] The length of the upper surface of the arc-shaped insert plate is shorter than the length of the lower surface of the arc-shaped insert plate. By setting the length of the arc-shaped insert plate, the shorter upper surface design can minimize the pressure on the wearer's chest, improve the wearing comfort, and ensure that the arc-shaped insert plate does not restrict the wearer's movements too much during activities.

[0011] A buffer telescopic rod is installed on the side of the arc-shaped plug plate away from the special-shaped ceramic sheet, and the telescopic end of the buffer telescopic rod is fixedly connected with the buffer plate. A buffer spring is installed on the side of the arc-shaped plug plate away from the special-shaped ceramic sheet, and the telescopic end of the buffer spring is fixedly connected to the outer surface of the buffer plate. By arranging the buffer telescopic rod, the buffer plate and the buffer spring, when the bullet hits the arc-shaped plug plate, the special-shaped ceramic sheet and the rectangular ceramic sheet as a whole, the arc-shaped plug plate is forced to squeeze the buffer telescopic rod and the buffer spring backwards, and the contraction of the buffer telescopic rod and the buffer spring can reduce the impact force of the arc-shaped plug plate, so as to improve the comfort and safety of the wearer.

[0012] A plurality of anti-skid protrusions are fixedly connected to one side of the buffer plate away from the arc-shaped plug plate, and the plurality of anti-skid protrusions are symmetrically distributed with the buffer plate as the center. By arranging the anti-skid protrusions, the friction force on the surface of the buffer plate can be increased. When the wearer moves, the arc-shaped plug plate can be prevented from shaking randomly as a whole, which may reduce the protective effect.

[0013] In summary, the technical effects and advantages of the utility model are as follows:

[0014] The multi-curved spliced ​​bulletproof ceramic sheet is designed with a slight thickness difference at the edge of each spliced ​​special-shaped ceramic sheet or rectangular ceramic sheet, so that multiple special-shaped ceramic sheets or rectangular ceramic sheets can be quickly spliced ​​into a whole and installed on the surface of the arc-shaped plug plate; at the same time, it is convenient to maximize the protection performance of the splicing of the special-shaped ceramic sheets or rectangular ceramic sheets, and the arc-shaped plug plate can continuously compress the buffer telescopic rod and the buffer spring when it moves backward under impact, and the contraction of the buffer telescopic rod and the buffer spring can minimize the impact force, so as to improve the comfort and safety of the wearer.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-2 , a multi-curved spliced ​​bulletproof ceramic sheet comprises an arc-shaped plug plate 1, a first positioning hole 2 is provided on the outer surface of the arc-shaped plug plate 1, a second positioning hole 3 is provided on the outer surface of the arc-shaped plug plate 1, and the radius of the first positioning hole 2 is smaller than the radius of the second positioning hole 3; a first fixing block 4 is fixedly connected to the inner surface of the arc-shaped plug plate 1, the first fixing block 4 is located in the first positioning hole 2, and a special-shaped ceramic sheet 5 is welded on the side of the first fixing block 4 away from the arc-shaped plug plate 1; a second fixing block 6 is fixedly connected to the inner surface of the arc-shaped plug plate 1, the second fixing block 6 is located in the second positioning hole 3, and a rectangular ceramic sheet 7 is welded on the side of the second fixing block 6 away from the arc-shaped plug plate 1, the special-shaped ceramic sheet 5 and the rectangular ceramic sheet 7 are made of the same material and are both bulletproof ceramic sheets; the edges of each piece of the special-shaped ceramic sheet 5 or the rectangular ceramic sheet 7 are slightly different in thickness, so that multiple special-shaped ceramic sheets 5 or the rectangular ceramic sheets 7 can be quickly assembled into a whole and installed on the surface of the arc-shaped plug plate 1; even if the bullet does not happen to hit the splicing, it still has good bulletproof performance.

[0022] Reference Figure 3 A load-bearing rod 8 is fixedly connected to the top of the arc-shaped plug plate 1, and a square handle 9 is installed on the top of the load-bearing rod 8. There are two load-bearing rods 8, and the two load-bearing rods 8 are symmetrically distributed with the arc-shaped plug plate 1 as the center, and the number of square handles 9 is equal to the number of load-bearing rods 8; the operator holds the square handle 9 and the load-bearing rod 8 to drive the arc-shaped plug plate 1 to move as a whole, so that the wearer can quickly put on or remove the arc-shaped plug plate 1 as a whole.

[0023] Reference Figure 1-3 The length of the upper surface of the arc-shaped plug plate 1 is shorter than the length of the lower surface of the arc-shaped plug plate 1. The shorter upper surface design can reduce the pressure of the arc-shaped plug plate 1 on the chest of the wearer, while ensuring that the arc-shaped plug plate 1 does not restrict the wearer's movements too much during activities. The longer lower surface of the arc-shaped plug plate 1 can provide a larger contact area, which helps to better disperse and absorb the impact force of the bullet.

[0024] Reference Figure 3A buffer telescopic rod 10 is installed on the side of the arc plug plate 1 away from the special-shaped ceramic sheet 5, and the telescopic end of the buffer telescopic rod 10 is fixedly connected with a buffer plate 11, and the length of the buffer plate 11 is less than the length of the arc plug plate 1; a buffer spring 12 is installed on the side of the arc plug plate 1 away from the special-shaped ceramic sheet 5, and the telescopic end of the buffer spring 12 is fixedly connected to the outer surface of the buffer plate 11; when the bullet hits the arc plug plate 1, the rectangular ceramic sheet 7 and the special-shaped ceramic sheet 5, the arc plug plate 1 is forced to move backward and squeeze the buffer telescopic rod 10 and the buffer spring 12, and the contraction of the buffer spring 12 and the buffer telescopic rod 10 can minimize the impact force of the arc plug plate 1, minimize the degree of damage to the wearer, and facilitate improving the comfort and safety of the wearer.

[0025] Reference Figure 3 A plurality of anti-skid protrusions 13 are fixedly connected to one side of the buffer plate 11 away from the arc-shaped plug plate 1. The height of the anti-skid protrusions 13 is less than the height of the buffer plate 11, and the plurality of anti-skid protrusions 13 are symmetrically distributed with the buffer plate 11 as the center; the installation of the anti-skid protrusions 13 can increase the friction force on the surface of the buffer plate 11; when the wearer moves quickly, the anti-skid protrusions 13 with increased friction force can be kept relatively stable as much as possible, and accidental shaking of the anti-skid protrusions 13 causing a reduction in protection can be avoided as much as possible.

[0026] Working principle: First, the special-shaped ceramic sheet 5 is installed on the surface of the arc plug plate 1 through the first fixing block 4, and the rectangular ceramic sheet 7 is installed on the surface of the arc plug plate 1 through the second fixing block 6. By designing a slight thickness difference at the edge of each piece of the special-shaped ceramic sheet 5 or rectangular ceramic sheet 7, it is convenient to quickly assemble multiple special-shaped ceramic sheets 5 or rectangular ceramic sheets 7 into a whole and install them on the surface of the arc plug plate 1, and when a single special-shaped ceramic sheet 5 or rectangular ceramic sheet 7 is accidentally damaged by impact, the wearer can also quickly remove the damaged special-shaped ceramic sheet 5 or rectangular ceramic sheet 7 and replace it; when the arc plug plate 1, the special-shaped ceramic sheet 5 and the rectangular ceramic sheet 7 are impacted, the arc plug plate 1 is forced to move backward and continuously compress the buffer telescopic rod 10 and the buffer spring 12, and the contraction of the buffer telescopic rod 10 and the buffer spring 12 can reduce the impact force as much as possible, and reduce the impact force suffered by the wearer as much as possible, so as to improve the comfort and safety of the wearer.
