[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 This utility model provides a technical solution:

[0030] A splicing rubber seal includes a sealing strip 1, with a mating interface 2 at one end and a connecting strip 3 at the end of the sealing strip 1 away from the mating interface 2. The size of the mating interface 2 is adapted to the size of the connecting strip 3. A bottom strip 4 is fixedly installed on the bottom surface of the sealing strip 1. An insert block 5 is fixedly installed at one end of the bottom strip 4. An insertion port 6 is fixedly installed on the side of the bottom strip 4 away from the insert block 5. The size of the insert block 5 is adapted to the size of the insertion port 6. Fixing members 7 are provided on the sides of the insert block 5 and the insertion port 6. The fixing member 7 includes an installation port 71 on the side of the insert block 5, a spring 72 disposed in the installation port 71, a fixing block 73 slidably disposed on the installation port 71, and a fixing port 74 on the bottom strip 4 located on the side of the insertion port 6. The two ends of the spring 72 are fixedly installed to the insert block 5 and the fixing block 73 respectively, and the spring 72 is pressed between the insert block 5 and the fixing block 73. The fixing block 73 and the fixing port 74 are configured as matching arc surfaces.

[0031] When splicing the sealing strip 1, the operator inserts the insert 5 on the side of the bottom strip 4 of one sealing strip 1 into the insert 6 on the side of the bottom strip 4 of another sealing strip 1. During the insertion of the insert 5 into the insert 6, the fixing block 73 is compressed by the squeezing force and the spring 72 enters into the installation port 71. When the insert 5 is fully inserted into the insert 6, the installation port 71 is directly opposite the fixing port 74. The elastic restoring force of the spring 72 will lock the fixing block 73 into the fixing port 74, thus completing the connection of the two sets of bottom strips 4.

[0032] During the connection of the two sets of bottom strips 4, the mating strip 3 also mates with the mating interface 2 to achieve splicing between the sealing strips 1. The connection between the mating strip 3 and the mating interface 2 can ensure the sealing performance. The bottom strip 4 can be used to install and fix the entire device.

[0033] This rubber seal enables easy splicing of the sealing strip 1, improving the applicability of the sealing strip 1.

[0034] A bottom plate 8 is fixedly installed inside the sealing strip 1, and a top plate 9 is fixedly installed inside the sealing strip 1. A uniformly distributed spring 10 is fixedly installed between the bottom plate 8 and the top plate 9.

[0035] When the sealing strip 1 is subjected to external pressure, since the bottom plate 8 is fixedly installed at the bottom inside the sealing strip 1 and the top plate 9 is fixedly installed at the top inside the sealing strip 1, and springs 10 are evenly distributed between the two, when the external pressure is transmitted to the sealing strip 1, the top plate 9 is stressed first and transmits the pressure to springs 10. Springs 10 are compressed and deformed under stress, and absorb part of the pressure through their own elastic deformation. The bottom plate 8 plays a supporting role, and the elastic restoring force of springs 10 will form a reverse resistance to the external pressure, so that the overall structure of the sealing strip 1 will not be easily damaged when subjected to pressure, effectively improving the pressure resistance performance and ensuring the sealing stability of the sealing strip 1 under various pressure environments, making it highly practical.

[0036] The dimensions of the base plate 8 and the top plate 9 are compatible with the inner diameter of the sealing strip 1;

[0037] The bottom plate 8 and the top plate 9 are matched in size and the inner diameter of the sealing strip 1. When the sealing strip 1 is under pressure, the top plate 9 can evenly transmit the pressure to each spring 10, which further enhances the ability of the spring 10 to absorb and resist pressure, thereby significantly improving the pressure resistance of the sealing strip 1.

[0038] The sealing strip 1 is made of flexible rubber, and the bottom strip 4 is made of rigid rubber.

[0039] The sealing strip 1 is made of flexible rubber. When the sealing strip 1 comes into contact with the part that needs to be sealed, it can fit tightly against the sealing surface, effectively fill the gap, prevent liquid or gas leakage, and ensure excellent sealing effect. The bottom strip 4 is made of hard rubber. Due to its high strength and stability, it supports the sealing strip 1 and prevents the sealing strip 1 from being excessively deformed during installation or use. It provides a stable foundation support for the sealing strip 1, improves the stability of the entire device under different working conditions, and ensures the reliable operation of the sealing strip 1.

[0040] Working principle:

[0041] When splicing the sealing strip 1, the operator inserts the insert 5 on the side of the bottom strip 4 of one sealing strip 1 into the insert 6 on the side of the bottom strip 4 of another sealing strip 1. During the insertion of the insert 5 into the insert 6, the fixing block 73 is compressed by the squeezing force and the spring 72 enters into the installation port 71. When the insert 5 is fully inserted into the insert 6, the installation port 71 is directly opposite the fixing port 74. The elastic restoring force of the spring 72 will lock the fixing block 73 into the fixing port 74, thus completing the connection of the two sets of bottom strips 4.

[0042] During the connection of the two sets of bottom strips 4, the mating strip 3 also mates with the mating interface 2 to achieve splicing between the sealing strips 1. The connection between the mating strip 3 and the mating interface 2 can ensure the sealing performance. The bottom strip 4 can be used to install and fix the entire device.

[0043] This rubber seal enables easy splicing of the sealing strip 1, improving the applicability of the sealing strip 1;

[0044] in,

[0045] When the sealing strip 1 is subjected to external pressure, since the bottom plate 8 is fixedly installed at the bottom of the sealing strip 1 and the top plate 9 is fixedly installed at the top of the sealing strip 1, and springs 10 are evenly distributed between the two, when the external pressure is transmitted to the sealing strip 1, the top plate 9 is stressed first and transmits the pressure to springs 10. Springs 10 are compressed and deformed under stress, and absorb part of the pressure through their own elastic deformation. The bottom plate 8 plays a supporting role, and the elastic restoring force of springs 10 will form a reverse resistance to the external pressure, so that the overall structure of the sealing strip 1 will not be easily damaged when it is subjected to pressure, effectively improving the pressure resistance performance, ensuring the sealing stability of the sealing strip 1 under various pressure environments, and making it highly practical.

[0046] The bottom plate 8 and the top plate 9 are matched with the inner diameter of the sealing strip 1. When the sealing strip 1 is under pressure, the top plate 9 can evenly transmit the pressure to each spring 10, which further enhances the ability of the spring 10 to absorb and resist pressure, thereby significantly improving the pressure resistance of the sealing strip 1.

[0047] The sealing strip 1 is made of flexible rubber. When the sealing strip 1 comes into contact with the part that needs to be sealed, it can fit tightly against the sealing surface, effectively fill the gap, prevent liquid or gas leakage, and ensure excellent sealing effect. The bottom strip 4 is made of hard rubber. Due to its high strength and stability, it supports the sealing strip 1 and prevents the sealing strip 1 from being excessively deformed during installation or use. It provides a stable foundation support for the sealing strip 1, improves the stability of the entire device under different working conditions, and ensures the reliable operation of the sealing strip 1.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
