[0005] The technical problem to be solved by the utility model is that when the composite glass is hit by a heavy object or impacted by a bullet, the glass is damaged due to excessive impact force, and the protection performance is low.

[0006] In order to solve the above technical problem, the technical solution of the utility model is as follows:

[0008] Preferably, the middle parts of the first buffer support bars and the second buffer support bars are bent in a V shape, both ends of the first buffer support bars and the second buffer support bars are bent and inclined inwards, and the inclination angles of the ends of the first buffer support bars and the second buffer support bars are the same as the inclination angles of the two sides of the first support bars and the second support bars and are attached to the first support bars and the second support bars.

[0009] Preferably, plug-in positioning holes are provided on the side edges where the first buffer support strip and the second buffer support strip are connected to each other. The width dimension of the plug-in positioning holes is the same as the thickness dimension of the first buffer support strip and the second buffer support strip.

[0013] 1. The first buffer support strip and the second buffer support strip are used to support the first support strip and the second support strip between the first support strip and the second support strip. When the outer tempered glass is impacted, the outer tempered glass squeezes the rubber buffer gasket towards the intermediate vacuum tempered glass. At this time, the rubber buffer gasket is compressed and the first support strip and the second support strip approach each other, causing the first buffer support strip and the second buffer support strip to be extruded and deformed and bent. At this time, the extruded first buffer support strip and the second buffer support strip provide a resistance force in the reverse direction to the outer tempered glass, canceling the impact force or impact received by the outer tempered glass, improving the buffer performance of the composite glass, and preventing the composite glass from directly breaking.

[0019] The following further describes the specific embodiments of the present utility model in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present utility model, but does not limit the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] As shown in Figure 1 , there is an intermediate vacuum tempered glass 2 between two outer tempered glasses 1. Rubber buffer gaskets 3 are installed between the intermediate vacuum tempered glass 2 and the adjacent outer tempered glasses 1. Glass glue is applied to the upper and lower surfaces of the rubber buffer gaskets 3. The rubber buffer gaskets 3 are adhesively fixed to the outer tempered glasses 1 and the intermediate vacuum tempered glass 2 through the glass glue.

[0021] As a preferred technical solution of this embodiment, as shown in Figure 2 and Figure 3 , a buffer colorless acrylic plate 4 is provided inside the rubber buffer gasket 3. First support bars 5 and second support bars 6 are installed inside the four side edges of the rubber buffer gasket 3. The first support bars 5 and the second support bars 6 are symmetrically arranged up and down. A plurality of groups of equally spaced first buffer support bars 7 and second buffer support bars 8 are installed between the first support bars 5 and the second support bars 6. The first buffer support bars 7 and the second buffer support bars 8 are snap-connected to each other and are rotationally symmetric in position. The first buffer support bars 7 and the second buffer support bars 8 support the first support bars 5 and the second support bars 6 from between the first support bars 5 and the second support bars 6. When the outer tempered glass 1 is impacted, the outer tempered glass 1 squeezes the rubber buffer gasket 3 towards the intermediate vacuum tempered glass 2. At this time, the rubber buffer gasket 3 is compressed and the first support bars 5 and the second support bars 6 approach each other, causing the first buffer support bars 7 and the second buffer support bars 8 to be squeezed and deformed and bent. At this time, the squeezed first buffer support bars 7 and the second buffer support bars 8 provide a resistance force in the opposite direction to the outer tempered glass 1 to offset the impact force or impulse force received by the outer tempered glass 1.

[0022] In this embodiment, the middle parts of the first buffer support bars 7 and the second buffer support bars 8 are bent in a V shape. The two ends of the first buffer support bars 7 and the second buffer support bars 8 are bent and inclined inwardly, and the inclined angles at the ends of the first buffer support bars 7 and the second buffer support bars 8 are the same as the inclined angles on both sides of the first support bars 5 and the second support bars 6 and are in contact with the first support bars 5 and the second support bars 6. By supporting the first support bars 5 and the second support bars 6 with the first buffer support bars 7 and the second buffer support bars 8, the first support bars 5 and the second support bars 6 ensure the structural stability of the rubber buffer gasket 3 and prevent it from collapsing inward.

[0023] The materials of the first buffer support bar 7 and the second buffer support bar 8 are both spring steel, and the first buffer support bar 7 and the second buffer support bar 8 are both formed by stamping.

[0024] As a preferred technical solution of this embodiment, as Figure 4 shown, the side edges where the first buffer support bar 7 and the second buffer support bar 8 are connected are both provided with insertion positioning holes 9. The width dimension of the insertion positioning holes 9 is the same as the thickness dimension of the first buffer support bar 7 and the second buffer support bar 8. The first buffer support bar 7 and the second buffer support bar 8 are fixedly clamped to each other through the insertion positioning holes 9, so that the first buffer support bar 7 and the second buffer support bar 8 form a symmetric elastic support structure, increasing the elastic buffering performance of the rubber buffer gasket 3, and offsetting and absorbing the impact or shock received by the outer tempered glass 1.

[0025] Working principle: When an external object impacts the outer tempered glass 1 or generates an impact on the outer tempered glass 1, the outer tempered glass 1 moves closer to the middle vacuum tempered glass 2 due to the impact or shock, and squeezes the buffer colorless acrylic plate 4 and the rubber buffer gasket 3. The buffer colorless acrylic plate 4 absorbs and offsets part of the impact or shock received by the outer tempered glass 1. At the same time, the rubber buffer gasket 3 is squeezed and deformed. At this time, the first support bar 5 and the second support bar 6 inside the rubber buffer gasket 3 will approach each other due to the transmitted impact or shock. The first buffer support bar 7 and the second buffer support bar 8 located between the first support bar 5 and the second support bar 6 are squeezed and deformed. After deformation, the first buffer support bar 7 and the second buffer support bar 8 provide a resistance force to the outer tempered glass 1 in the opposite direction, preventing the outer tempered glass 1 from continuing to squeeze towards the middle vacuum tempered glass 2. The impact force or impact received by the outer tempered glass 1 is offset by the elastically deformable rubber buffer gasket 3, the first buffer support bar 7, and the second buffer support bar 8, improving the buffering performance of the composite glass and preventing the composite glass from directly breaking.

[0026] The above has described in detail the embodiments of the present invention in conjunction with the drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present invention.
