Description

Technical Field

[0001] The utility model relates to the technical field of bulletproof technology, and particularly relates to a new type of laminated bulletproof glass. Background Technique

[0002] Laminated bulletproof glass is a special glass composed of multiple layers of glass and a special laminated material (such as polycarbonate polymer PC or polyvinyl butyral polymer PVB, etc.). It can effectively prevent bullets from penetrating when being shot at by bullets;

[0003] Laminated bulletproof glass usually consists of a load-bearing layer, a transition layer, and a safety protection layer. The load-bearing layer bears the impact first and breaks, the transition layer uses an organic adhesive material to absorb the impact energy and change the direction of the bullet, and the safety protection layer uses high-strength glass or transparent organic materials to ensure that the bullet cannot penetrate.

[0004] However, the impact resistance of this kind of laminated bulletproof glass is relatively low, and it can only absorb the impact force through the impact position. Moreover, when the laminated bulletproof glass is shot, glass fragments will fly out, thus causing harm to the people around; Therefore, it does not meet the existing requirements, and for this reason, we propose a new type of laminated bulletproof glass. Content of the Utility Model

[0005] The purpose of the utility model is to provide a new type of laminated bulletproof glass to solve the problems raised in the above background technique, such as the relatively low impact resistance of this kind of laminated bulletproof glass, which can only absorb the impact force through the impact position, and when the laminated bulletproof glass is shot, glass fragments will fly out, thus causing harm to the people around.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A new type of laminated bulletproof glass, including a bulletproof glass frame, on one side inside the bulletproof glass frame, a laminated bulletproof glass is fixedly provided. On one side inside the laminated bulletproof glass, a corrugated tempered glass plate A is provided. On one side of the corrugated tempered glass plate A, a corrugated tempered glass plate B is provided. The corrugated tempered glass plate A and the corrugated tempered glass plate B as a whole are in a corrugated shape. On the surface of the corrugated tempered glass plate A facing the corrugated tempered glass plate B, a plurality of riveting grooves A are provided. On the surface of the corrugated tempered glass plate B facing the corrugated tempered glass plate A, a plurality of riveting grooves B are provided. The corrugated tempered glass plate A and the corrugated tempered glass plate B are riveted through the riveting grooves A and the riveting grooves B, and polycarbonate fibers are provided in the gap between the corrugated tempered glass plate A and the corrugated tempered glass plate B and on its outer side;

[0007] On one side of the laminated bulletproof glass, there is a slag collection mechanism, which includes an elastic connection mechanism, a slag collection plate, and a collection groove. The collection groove is located on the surface of the slag collection plate facing the laminated bulletproof glass, and the slag collection plate is installed inside the bulletproof glass frame through the elastic connection mechanism.

[0008] Preferably, the bottom end and the middle part of the laminated bulletproof glass are both located inside the collection groove, and the outer surface of the laminated bulletproof glass located inside the collection groove fits with the inner wall of the collection groove.

[0009] Preferably, the elastic connection mechanism includes a loop frame. Four end corners of the lower end face of the loop frame are each fixedly provided with a guide rod, and through holes located on the lower end face of the bulletproof glass frame are provided on the outer side of the bottom end of the guide rod.

[0010] Preferably, a spring is sleeved on the outer surface of the guide rod, and the upper and lower ends of the spring are respectively connected between the loop frame and the inside of the bulletproof glass frame.

[0011] Preferably, the outer surface of the slag collection plate fits with the inner wall of the bulletproof glass frame, and the slag collection plate is slidably connected to the bulletproof glass frame.

[0012] Preferably, a fixing ring is fixedly sleeved on the upper side of the outer surface of the laminated bulletproof glass, and the fixing ring is fixed to the bulletproof glass frame.

[0013] Preferably, a loop-shaped metal cover plate located on the lower end face of the bulletproof glass frame is provided below the loop frame, and the bulletproof glass frame and the loop-shaped metal cover plate are fixed by screws.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. When this device needs to be used, the upper end face of the laminated bulletproof glass faces the outside. Inside the laminated bulletproof glass, there are a corrugated tempered glass plate A and a corrugated tempered glass plate B that are riveted through a riveting groove A and a riveting groove B. When the upper end face of the laminated bulletproof glass is shot, the impact force will pass through the laminated bulletproof glass and be transmitted to the riveted corrugated tempered glass plate A and corrugated tempered glass plate B. Since the toughness of the polycarbonate fiber is very high but its hardness is insufficient, when the riveted corrugated tempered glass plate A and corrugated tempered glass plate B located inside the polycarbonate fiber are impacted, the whole will deform accordingly. Through the above technical solution, when the laminated bulletproof glass is shot, the overall stress area is increased, thereby dispersing the impact force and improving the overall strength of the device.

[0016] 2. When the upper end face of the laminated bulletproof glass is shot and fragments fly out from its lower end face, the impact force will push down the slag collection plate installed inside the bulletproof glass frame through the elastic connection mechanism, so as to collect the flying fragments into the collection groove on the outer surface of the slag collection plate. Through the above technical solution, the flying fragments can be collected, thus improving the safety of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] The laminated bulletproof glass 2 (model number nss005), guide rod 9 (model number 304), and spring 11 (model number JX110) mentioned in the present utility model can be obtained by purchasing from the market or customizing privately.

[0024] Such as Figure 1 and Figure 2As shown in the figure, an embodiment provided by the present utility model is a new type of laminated bulletproof glass, which includes a bulletproof glass frame 1. On one side inside the bulletproof glass frame 1, a laminated bulletproof glass 2 is fixedly provided. On one side inside the laminated bulletproof glass 2, a wavy tempered glass plate A 3 is provided. On one side of the wavy tempered glass plate A 3, a wavy tempered glass plate B 12 is provided. The wavy tempered glass plate A 3 and the wavy tempered glass plate B 12 as a whole are in a wavy shape. On the surface of the wavy tempered glass plate A 3 facing the wavy tempered glass plate B 12, a plurality of riveting grooves A 5 are provided. On the surface of the wavy tempered glass plate B 12 facing the wavy tempered glass plate A 3, a plurality of riveting grooves B 13 are provided. The wavy tempered glass plate A 3 and the wavy tempered glass plate B 12 are riveted through the riveting grooves A 5 and the riveting grooves B 13. And a polycarbonate fiber 4 is provided in the gap between the wavy tempered glass plate A 3 and the wavy tempered glass plate B 12 and on its outside.

[0025] As a preferred technical solution of this embodiment, as Figure 3 and Figure 4 shown, a fixing ring 14 is fixedly sleeved on the upper side of the outer surface of the laminated bulletproof glass 2, and the fixing ring 14 is fixed to the bulletproof glass frame 1; the laminated bulletproof glass 2 is fixed inside the bulletproof glass frame 1 through the fixing ring 14. When this device needs to be used, the upper end surface of the laminated bulletproof glass 2 faces the outside. Inside the laminated bulletproof glass 2, there are a wavy tempered glass plate A 3 and a wavy tempered glass plate B 12 that are riveted through the riveting grooves A 5 and the riveting grooves B 13. When the upper end surface of the laminated bulletproof glass 2 is shot, the impact force will pass through the laminated bulletproof glass 2 and then be transmitted to the riveted wavy tempered glass plate A 3 and the wavy tempered glass plate B 12. Since the polycarbonate fiber 4 has high toughness but insufficient hardness, when the riveted wavy tempered glass plate A 3 and the wavy tempered glass plate B 12 inside the polycarbonate fiber 4 are impacted, the whole will deform accordingly. Through this embodiment, when the laminated bulletproof glass 2 is shot, the overall stress area is increased, so as to disperse the impact force and thus improve the overall strength of the device.

[0026] As a preferred technical solution of this embodiment, as Figure 3As shown in the figure, a slag collection mechanism is provided on one side of the laminated bulletproof glass 2. The slag collection mechanism includes an elastic connection mechanism, a slag collection plate 6, and a collection groove 7. The collection groove 7 is located on the surface of the slag collection plate 6 facing the laminated bulletproof glass 2, and the slag collection plate 6 is installed inside the bulletproof glass frame 1 through the elastic connection mechanism; both the bottom end and the middle part of the laminated bulletproof glass 2 are located inside the collection groove 7, and the outer surface of the laminated bulletproof glass 2 located inside the collection groove 7 is in contact with the inner wall of the collection groove 7; the elastic connection mechanism includes a return frame 8, and a guide rod 9 is fixedly provided at each of the four end corners of the lower end surface of the return frame 8, and a through hole 10 located on the lower end surface of the bulletproof glass frame 1 is provided on the outer side of the bottom end of the guide rod 9; a spring 11 is sleeved on the outer surface of the guide rod 9, and the upper and lower ends of the spring 11 are respectively connected between the return frame 8 and the inside of the bulletproof glass frame 1; the outer surface of the slag collection plate 6 is in contact with the inner wall of the bulletproof glass frame 1, and the slag collection plate 6 is slidably connected with the bulletproof glass frame 1; through the spring force of the spring 11, it can be ensured that the laminated bulletproof glass 2 is always in contact with the inner wall of the collection groove 7. When the upper end surface of the laminated bulletproof glass 2 is shot and fragments fly out from its lower end surface, they will enter the inside of the collection groove 7 on the outer surface of the slag collection plate 6, and their impact force will offset the spring force of the spring 11 and thus push the slag collection plate 6 downward, so as to create a gap between the lower end surface of the polycarbonate fiber 4 and the inner wall of the collection groove 7, and the flying fragments will enter the gap between the polycarbonate fiber 4 and the inner wall of the collection groove 7. Through the above technical solution, the flying fragments can be collected, thereby improving the safety of the equipment.

[0027] A return-shaped metal cover plate located on the lower end surface of the bulletproof glass frame 1 is provided below the return frame 8, and the bulletproof glass frame 1 and the return-shaped metal cover plate are fixed by screws; through the return-shaped metal cover plate, the connection between the fixing ring 14 and the return frame 8 and the bulletproof glass frame 1 can be isolated from the outside, so as to protect it.
