[0002] Rubber seals are a kind of sealing material used to prevent liquid or gas leakage. They are usually made of rubber materials and have the characteristics of softness, elasticity and wear resistance. Rubber seals are widely used in automobiles, mechanical equipment, pipeline systems and other fields to play the role of sealing, shock absorption, waterproofing, etc. In engineering design, choosing the right rubber seal can ensure the normal operation of the equipment and extend the service life of the equipment.

[0003] After searching, Chinese patent announcement number: CN220102046U discloses an assembled rubber seal, including a first connecting ring, a sealing gasket is fixedly connected inside the first connecting ring, a support block is slidably connected to the inner wall of the sealing gasket, a fixing plate is fixedly connected to the outer side of the support block, a rotating shaft is fixedly connected to one side of the outer wall of the fixing plate, the rotating shaft is arranged inside the connecting rod, the outer wall of the connecting rod is fixedly connected to a limiting plate, and a screw is arranged inside the first fixing ring. In the utility model, the effect of stretching the rubber seal is firstly achieved through the cooperation between the rotating shaft, the connecting rod, the screw, the fixing block and the supporting block, thereby solving the problem that the rubber seal is deformed during long-term use, thereby causing it to be unusable, and then the cooperation between the first connecting ring, the second connecting ring, the threaded hole and the screw can achieve the effect of installing the two sealing gaskets.

[0004] Although the above device expands the rubber seal by arranging a rotating shaft, a connecting rod, a screw rod, a fixed block and a supporting block to prevent the seal from being easily deformed during long-term use, the sealing gasket generally needs to be snapped into the groove of other components or fixed to the outside of the object, and all these parts are installed on the inner wall of the sealing gasket, which is easy to affect the connection between the sealing gasket and other components. At the same time, the structure is relatively complicated, which is easy to lead to increased production costs. Therefore, an assembled rubber seal is proposed to solve the above problems.

[0034] See also Figure 2 and Figure 6 The No. 1 sealing ring 2 is provided with a plurality of connecting ports 21 for cooperating with the connection of the fixing member 41. A fixing ring 22 is fixedly connected to the bottom surface of the No. 1 sealing ring 2 for connecting with the No. 2 sealing ring 4. The fixing ring 22 is larger in volume at the end away from the No. 1 sealing ring 2 and has a cavity inside. A clamping ring 23 is fixedly connected to the bottom surface of the No. 1 sealing ring 2 for connecting with the No. 2 sealing ring 4 to enhance the sealing performance. A No. 1 mounting groove 24 adapted to the reinforcement member 5 is provided on the bottom surface of the No. 1 sealing ring 2 for clamping the reinforcement ring 51. A No. 1 mounting port 241 is provided at the bottom of the No. 1 mounting groove 24 for cooperating with the installation and fixation of the reinforcement member 5.

[0035] like Figure 3 and Figure 5As shown, the top of the No. 2 sealing ring 4 is fixedly connected with a fixing member 41 for connecting with the No. 1 sealing ring 2, the fixing member 41 includes a fixing column 411, the top of the fixing column 411 is fixedly connected with a fixing block 412 for fixing the No. 1 sealing ring 2 and the No. 2 sealing ring 4, the fixing column 411 and the fixing block 412 are movably connected with the connecting port 21, the top of the No. 2 sealing ring 4 is provided with a fixing groove 42 for cooperating with the clamping of the fixing ring 22, the shape of which is adapted to the fixing ring 22, the fixing ring 22 is clamped therewith, the top of the No. 2 sealing ring 4 is provided with a clamping groove 43, the clamping ring 23 is clamped therewith, the bottom surface of the No. 2 sealing ring 4 is provided with a No. 2 mounting groove 44 adapted to the reinforcement member 5, for cooperating with the connection of the reinforcement ring 51, the top of the No. 2 mounting groove 44 is provided with a No. 2 mounting port 441 for cooperating with the installation of the reinforcement member 5.

[0036] Furthermore, the reinforcement member 5 includes a reinforcement ring 51 for reinforcing the sealing ring and for connecting multiple reinforcement columns 52. The reinforcement ring 51 is movably connected to the No. 1 mounting groove 24 or the No. 2 mounting groove 44. The reinforcement ring 51 is fixedly connected to one side of the No. 1 sealing gasket 1 or the No. 2 sealing gasket 3 with multiple reinforcement columns 52 for providing support for the sealing gasket so that it is not easily deformed during long-term use. The middle part of the No. 1 sealing gasket 1 is provided with a No. 1 auxiliary groove 11 that is compatible with the reinforcement column 52, and the middle part of the No. 2 sealing gasket 3 is provided with a No. 2 auxiliary groove 31 that is compatible with the reinforcement column 52, for coordinating the connection between the reinforcement member 5 and the sealing gasket.

[0037] Working principle: During use, according to the use requirements, when the seal needs to be reinforced to prevent it from deformation due to long-term use, the reinforcement 5 can be installed in the seal. When the No. 1 seal needs to be installed with the reinforcement 5, the No. 1 installation port 241 is opened by hand, and then the reinforcement 5 is installed into the No. 1 seal, so that the reinforcement ring 51 is inserted into the No. 1 installation groove 24, and the reinforcement column 52 is inserted into the No. 1 auxiliary groove 11, and then the No. 1 installation port 241 is loosened. The steps for installing the reinforcement 5 on the No. 2 seal are the same.

[0038] When it is necessary to fix the two seals together, first insert the retaining ring 23 into the retaining groove 43, and then force the fixing ring 22 into the fixing groove 42. Since a cavity is provided inside the end of the fixing ring 22 away from the No. 1 sealing ring 2 and the volume of this side is slightly larger than the other side, and since the shape of the fixing groove 42 is adapted to the shape of the fixing ring 22, when the larger end of the fixing ring 22 is installed into the fixing groove 42, the internal cavity will be squeezed. When the fixing ring 22 is fully inserted into the fixing groove 42, the cavity will be restored, so that the fixing ring 22 and the fixing groove 42 are completely stuck. Then align the fixing piece 41 with the connecting port 21 and press it into the connecting port 21. After the fixing piece 41 is inserted into the connecting port 21, the fixing block 412 on the top of the fixing column 411 will be stuck on one side of the connecting port 21, so that the No. 1 sealing ring 2 and the No. 2 sealing ring 4 are completely fixed, so that the No. 1 seal and the No. 2 seal are completely assembled.
