[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rubber seal includes a lower rubber ring and an upper rubber ring connected to the top of the lower rubber ring. The lower rubber ring has a bottom insertion ring at the middle of its lower surface for bottom sealing insertion. Sealing rings are provided on both sides of the lower rubber ring near the bottom. The upper rubber ring has a double limiting ring at the top for top sealing insertion. Several rubber strips are provided on both sides of the lower and upper rubber rings.

[0011] In this invention, with the cooperation of the second vacuum layer, the material of the upper rubber ring is further increased, and it works in conjunction with the first vacuum layer to provide double protection, thereby increasing the corresponding sound insulation and heat insulation.

[0012] Preferably, the width of the outer wall of the lower rubber ring is adapted to the width of the outer wall of the upper rubber ring, and the upper surface of the lower rubber ring is bonded and fixed to the lower surface of the upper rubber ring.

[0013] In this invention, the mutual bonding and cooperation increases the stability of the overall assembly.

[0014] Preferably, the sealing ring is circular, one side of the sealing ring is fused and fixed to the lower rubber ring, the bottom of the bottom insert ring is circular cylindrical, and the top of the bottom insert ring is fused and fixed to the center of the lower surface of the lower rubber ring.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This utility model achieves a double-layer sealing fit by setting a lower rubber ring with a first vacuum layer and an upper rubber ring with a second vacuum layer. The combination of the first and second vacuum layers increases the sound and heat insulation performance. The installation of the sealing ring increases the contact area between the bottom of the lower rubber ring and the external object, thus increasing the sealing performance. The bottom insertion ring increases the stability of the lower rubber ring when inserted into the external object. The combination of the double limiting rings increases the tightness of the top of the upper rubber ring when inserted into the external object.

[0022] 2. This utility model increases the overall support toughness by setting multiple rubber strips, and helps the overall structure to quickly recover after compression deformation. The first vacuum layer and the second vacuum layer work together to increase the overall recovery ability and reduce the impact of deformation on the overall installation and use. In addition, the first vacuum layer and the second vacuum layer reduce the amount of material used to make the lower rubber ring and the upper rubber ring, thus reducing the overall weight.

[0034] A rubber seal includes a lower rubber ring 1 and an upper rubber ring 2 connected to the top of the lower rubber ring 1. The hollow area between the inner wall and the outer wall of the lower rubber ring 1 is a first vacuum layer 11.

[0035] In this invention, the first vacuum layer 11 reduces the amount of material used to make the lower rubber ring 1, while increasing sound and heat insulation.

[0036] Furthermore, the hollow area between the inner and outer walls of the upper rubber ring 2 is the second vacuum layer 21.

[0037] In this invention, with the cooperation of the second vacuum layer 21, the material of the upper rubber ring 2 is further increased. At the same time, it cooperates with the first vacuum layer 11 to provide double protection and increase the corresponding sound insulation and heat insulation. With the cooperation of the first vacuum layer 11 and the second vacuum layer 21, the recovery after overall compression is increased and the overall deformation is reduced.

[0038] Specifically, the hollow area between the inner and outer walls of the upper rubber ring 2 is the second vacuum layer 21.

[0039] In this invention, with the cooperation of the second vacuum layer 21, the material of the upper rubber ring 2 is further increased. At the same time, it cooperates with the first vacuum layer 11 to provide double protection and increase the corresponding sound insulation and heat insulation. With the cooperation of the first vacuum layer 11 and the second vacuum layer 21, the recovery after overall compression is increased and the overall deformation is reduced.

[0040] It should be noted that a bottom insertion ring 3 for bottom sealing is provided in the middle of the lower surface of the lower rubber ring 1. A sealing ring 10 is provided on both sides of the lower rubber ring 1 near the bottom. The sealing ring 10 is circular. One side of the sealing ring 10 is fused and fixed to the lower rubber ring 1. The bottom of the bottom insertion ring 3 is circular cylindrical. The top of the bottom insertion ring 3 is fused and fixed to the center of the lower surface of the lower rubber ring 1.

[0041] In this invention, with the cooperation of the sealing ring 10, the contact area between the bottom of the lower rubber ring 1 and the external object is increased, thereby increasing the sealing performance. With the cooperation of the bottom insertion ring 3, the lower rubber ring 1 and the bottom are stably inserted and installed with the external object.

[0042] Furthermore, the top of the upper rubber ring 2 is provided with a double limiting ring 20 for top sealing insertion. The top of the double limiting ring 20 is in the shape of a cylindrical ring, and the bottom of the double limiting ring 20 is fused and fixed to the center of the upper surface of the upper rubber ring 2.

[0043] In this invention, the double limiting rings 20 help the top of the upper rubber ring 2 to fit tightly against the external object, and the double-layer insertion further increases the tightness of the top installation.

[0044] It is worth adding that several rubber strips 4 are provided on both sides of the lower rubber ring 1 and the upper rubber ring 2.

[0045] Secondly, the top of the double limiting ring 20 is in the shape of a cylindrical ring, and the bottom of the double limiting ring 20 is fused and fixed to the center of the upper surface of the upper rubber ring 2.

[0047] When using the rubber seal of this embodiment, the user first glues and combines the lower rubber ring 1 with the first vacuum layer 11 and sealing ring 10 with the upper rubber ring 2 with the second vacuum layer 21 and double limiting ring 20. Then, the top of the bottom insert ring 3 is glued and fixed to the bottom of the lower rubber ring 1, and multiple rubber strips 4 are fixed on both sides of the lower rubber ring 1 and the upper rubber ring 2 in sequence.

[0048] When two objects need to be connected, with the cooperation of the bottom insertion ring 3, the bottom of the lower rubber ring 1 is inserted and installed with the object below, and the sealing ring 10 is in close contact with the object below to increase the sealing performance. With the cooperation of the double limiting ring 20, it is tightly inserted and installed with the object above, so as to achieve quick and stable assembly. With the cooperation of the first vacuum layer 11 and the second vacuum layer 21, the sound insulation and heat insulation at the connection point are increased. With the cooperation of the rubber strip 4, the overall toughness is increased, and it is easy to recover quickly after being squeezed, reducing the impact of deformation on the sealing performance.
