Description

Technical Field

[0001] The utility model relates to the technical field of bullet-proof plates, in particular to a connected PE bullet-proof plate. Background Art

[0002] The bulletproof plate is the main body of bulletproof equipment. Its main purpose is to effectively prevent gunfire and protect the lives of personnel. Existing bulletproof plates are often ceramic composite bulletproof plates.

[0003] Ceramic composite bulletproof inserts are usually made by bonding small ceramic pieces of different shapes to a fiber fabric laminate through a process of isothermal static pressing with a film, or by directly bonding a whole ceramic piece to a fiber fabric laminate using an adhesive to form a single curved surface composite insert.

[0004] After being hit by a bullet, the entire ceramic plate will splash and fall off. After the entire ceramic plate is shattered by a bullet, the entire plate is likely to break into a large number of small fragments, which reduces the subsequent bulletproof performance of the bulletproof plate. When assembling a composite bulletproof plate formed by splicing multiple ceramic plates, the small ceramic plates must be spliced together first, and gaps will be generated when the small ceramic plates are spliced, which increases the probability of penetration of the bulletproof plate when it is bulletproof. Summary of the Invention

[0005] The purpose of the utility model is to provide a spliced PE bulletproof plate with firm splicing and increased strength of gaps between spliced ceramic sheets in response to the deficiencies in the prior art.

[0006] In order to achieve the above purpose, the technical solution adopted by the present invention is: a spliced PE bulletproof plate, the bulletproof plate includes a plurality of ceramic plate monomers, the ceramic plate monomers are formed by combining in an I-shaped manner, a rectangular through hole is provided in the middle of the ceramic plate monomer that passes through the upper and lower bottom surfaces, the ceramic plate monomer includes a main body, an L-shaped plate, a convex plate and a Z-shaped plate, the L-shaped plate and the convex plate are arranged at the left end of the main body, the L-shaped plate, the convex plate and the main body are surrounded to form a notch groove, the Z-shaped plate is arranged at the right end of the main body, the Z-shaped plate and the main body are surrounded to form an L-shaped groove, the Z-shaped plate The end faces of the plates are formed with grooves, and the left and right adjacent ceramic plate units are connected by plugging in the notched grooves and the Z-shaped plates. The grooves of the left and right adjacent ceramic plate units are connected by plugging in the corresponding convex plates. The L-shaped plates of the left and right adjacent ceramic plate units are connected by plugging in the corresponding L-shaped grooves. The L-shaped plates and Z-shaped plates of the left and right adjacent ceramic plate units are enclosed to form a splicing through-hole. The splicing through-holes of the upper and lower adjacent ceramic plate units correspond to the shape, size and position of the rectangular through-holes. Connecting strips are provided to pass through and connect the splicing through-holes and the rectangular through-holes. It should be further explained that the upper and lower adjacent ceramic plates are connected together by connecting strips to increase the integrity in the vertical direction, and the left and right adjacent ceramic plates are connected together by L-shaped plates, convex plates and Z-shaped plates to increase the integrity in the horizontal direction. The ceramic plates are combined together in an I-shaped manner to avoid the concentration of splicing seams and enhance the overall strength of the ceramic plates after splicing.

[0007] Preferably, a buffer gap in the front-to-back direction is left at the joints between the L-shaped plate and the Z-shaped plate of the left and right adjacent ceramic plate units.

[0008] Preferably, the connecting strips include a rigid core strip and a cushioning layer covering the rigid core strip. It should be further explained that when a ceramic plate is hit by a bullet, it will produce a significant impact on the joints. To mitigate the collision at the joints during the impact, a buffer gap is provided to provide a certain buffer between the joints of the ceramic plates. Combined with the rigid core strip and cushioning layer in the connecting strips, the impact force is dispersed to adjacent ceramic plates, reducing concentrated damage to individual ceramic plates and increasing the durability of the bulletproof plate.

[0009] Preferably, the rigid core bar is an iron core, and the buffer layer is rubber.

[0010] Preferably, the bulletproof plate is formed by compositely forming an ultra-high molecular weight polyethylene cloth, a film, and a ceramic plate by static pressing at room temperature.

[0011] Preferably, the front surface of the ceramic plate unit is square or quadrilateral.

[0012] Compared with the prior art, the present invention has the following advantages: before the isothermal static pressing whole-plate composite process, the present invention integrates the ceramic plate monomers into a whole ceramic plate, which facilitates the composite of the ceramic plate and the high-molecular-weight polyethylene cloth through the adhesive film; the left and right adjacent ceramic plate monomers are tightly spliced by L-shaped plates, Z-shaped plates, convex plates and connecting strips, and the connecting strips simultaneously connect the upper and lower adjacent ceramic plate monomers. The connecting strips absorb the impact on the ceramic plate and disperse the impact to the surrounding ceramic plate monomers, reducing the concentrated damage to the ceramic plate monomers, increasing the structural strength of the splicing, and improving the overall durability of the bulletproof plate.

[0017] The present invention is further illustrated below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, modifications of various equivalent forms of the present invention by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0018] like Figures 1 to 3The spliced PE bulletproof plate shown is formed by isothermal static pressing of ultra-high molecular weight polyethylene cloth, film, and ceramic plate. The bulletproof plate includes several ceramic plate monomers 1. The front of the ceramic plate monomer 1 is square or square. The ceramic plate monomers 1 are formed by I-shaped splicing. A rectangular through hole 18 is provided in the middle of the ceramic plate monomer 1 that passes through the upper and lower bottom surfaces. Since the ceramic plate monomer 1 is formed by integral pressing, the ceramic plate monomer 1 is divided for the convenience of distinguishing and explaining each part. The dividing lines between the various parts are indicated by dotted lines in the figure. The ceramic plate monomer 1 includes a main body 11, an L-shaped plate 12, a convex plate 13, and a Z-shaped plate 15. The L-shaped plate 12 and the convex plate 13 are provided at the left end of the main body 11. The L-shaped plate 12, the convex plate 13 and the main body 11 are enclosed to form a notch groove 14, and the Z-shaped plate 15 is provided at the right end of the main body 11. The Z-shaped plate 15 and the main body 11 are enclosed to form an L-shaped groove 16. The end face of the Z-shaped plate 15 is formed with a groove 17, wherein the vertical distance from the short plate of the L-shaped plate 12 to the front end face of the main body 11 is greater than the length of the contact edge of the Z-shaped plate 15 and the main body 11. The right end face length of the Z-shaped plate 15 is less than the vertical distance from the long plate of the L-shaped plate 12 to the convex plate 13. The ceramic plate monomers 1 adjacent to the left and right are connected by plugging with the notch groove 14 and the Z-shaped plate 15. The grooves 17 of the ceramic plate monomers 1 adjacent to the left and right correspond to the convex plate 13. The plates 13 are plugged in to form a connection, and the L-shaped plates 12 of the left and right adjacent ceramic plate monomers 1 are plugged in to form a connection corresponding to the L-shaped grooves 16. The L-shaped plates 12 and Z-shaped plates 15 of the left and right adjacent ceramic plate monomers 1 are surrounded to form a splicing through-hole 32. A buffer gap 31 in the front-to-back direction is left at the splicing of the L-shaped plates 12 and Z-shaped plates 15 of the left and right adjacent ceramic plate monomers 1. The splicing through-holes 32 of the upper and lower adjacent ceramic plate monomers 1 correspond to the shape, size and position of the rectangular through-hole 18. A connecting strip 2 is provided to pass through the splicing through-hole 32 and the rectangular through-hole 18. The connecting strip 2 includes an iron core 21 and a rubber 22 covering the rigid core strip.

[0019] The working process and principle of the present invention are as follows: during the insertion process of the ceramic plate monomer 1, the Z-shaped plate 15 of the left ceramic plate monomer 1 is first aligned with the convex plate 13 and translated to the right. When the Z-shaped plate 15 abuts against the convex plate 13, the left ceramic plate monomer 1 is translated backward so that the Z-shaped plate 15 enters the notch groove 14 while the convex groove is aligned with the convex plate 13. The left ceramic plate monomer 1 is translated to the right until the Z-shaped plate 15 abuts against the main body 11 of the right ceramic plate monomer 1. At this time, a splicing through hole 32 is formed at the splicing position, and the connecting strip 2 is inserted into the splicing through hole 32 to achieve fixation.
