Description

Technical Field

[0001] This utility model relates to the field of rubber sealing gasket technology, and in particular to a novel rubber sealing gasket based on a thermo-pressed connection structure. Background Technology

[0002] A rubber gasket is a rubber product used to fill the gap between two or more components to prevent leakage of fluids (such as gases or liquids). Depending on the application environment and requirements, rubber gaskets can be made from different materials and formulations. Common rubber materials include natural rubber, nitrile rubber, neoprene rubber, and EPDM rubber.

[0003] Chinese patent CN218582236U discloses a rubber sealing gasket based on a thermo-pressed connection structure. This technical solution, through the cooperation between the mounting plate, the connecting rod, the elastic ball, and the buffer spring, allows the buffer spring to extend and retract when the pipeline vibrates and collides with the sealing gasket, while the elastic ball deforms. The force is absorbed by the elastic action of the buffer spring and the elastic ball, thereby buffering the sealing gasket and preventing it from deforming too much and failing.

[0004] However, this new type of rubber sealing gasket based on a thermo-pressed connection structure is used in an integrated manner, with its internal elastic buffer structure fixed inside the sealing gasket, which makes the subsequent inspection and maintenance of the rubber sealing gasket inconvenient.

[0005] Therefore, it is necessary to provide a new type of rubber sealing gasket based on a thermo-pressed connection structure to solve the above-mentioned technical problems. Summary of the Invention

[0006] This utility model provides a novel rubber sealing gasket based on a thermo-pressed connection structure. The technical problem it solves is that in the prior art, the novel rubber sealing gasket based on a thermo-pressed connection structure adopts an integrated approach during use, which makes the subsequent inspection and maintenance of the rubber sealing gasket inconvenient.

[0007] To solve the above technical problems, the present invention provides a novel rubber sealing gasket based on a thermo-pressed connection structure, comprising an annular component, wherein the front and rear sides of the annular component are provided with receiving grooves, a movable ring that moves in the horizontal direction is provided inside the receiving groove, and a sealing gasket is fixedly connected to the outer side of the movable ring.

[0008] The annular component has several cavities on its sidewall. Several connecting rods are fixedly connected to the inner side of the movable ring. Each connecting rod corresponds to one of the cavities. The inner end of each connecting rod is pulled out and extends into the cavity and is fixedly connected to an abutment block. Several sealing plates are detachably installed on the sidewall of the annular component. A fixing block is fixedly connected to the inner side of each sealing plate. An elastic ball that matches the abutment block is fixedly connected to the other end of each fixing block.

[0009] Preferably, the sealing plate is provided with a plurality of bolts, and the side wall of the annular member is provided with a plurality of threaded holes adapted to the bolts.

[0010] Preferably, a handle is fixedly connected to the outer side of the sealing plate.

[0011] Preferably, the surface of the contact block has a bevel that is adapted to the elastic ball.

[0012] Preferably, a sliding ring is fixedly connected to the side wall of the movable ring, and a sliding groove is provided inside the receiving groove for the sliding ring to move.

[0013] Preferably, four cavities are provided, and the four cavities are evenly spaced and distributed in a ring along the sidewall of the annular member.

[0014] Compared with related technologies, the novel rubber sealing gasket based on a thermo-pressed connection structure provided by this utility model has the following beneficial effects:

[0015] This invention provides a novel rubber sealing gasket based on a thermo-pressed connection structure. When the sealing gasket is compressed, it drives the moving ring to slide inside the receiving groove. By utilizing the connection between the two connecting rods, the two contact blocks compress the elastic ball to generate elastic force. The elastic force of the elastic ball reacts to the two connecting rods, thus buffering the sealing gasket when it is compressed, preventing the sealing gasket from deforming under excessive pressure, and improving the stability of the sealing process. Furthermore, the sealing plate can be disassembled from the surface of the ring, facilitating the removal and maintenance of the elastic ball. The prefabricated structure improves the convenience of later maintenance operations, and when some components are severely worn, they can be replaced individually, reducing the maintenance cost of the rubber sealing gasket.

Receiving grooves 3 are provided on both the front and rear sides of the annular component 1. A moving ring 4 that moves horizontally is disposed inside the receiving grooves 3. A sealing gasket 5 is fixedly connected to the outer side of the moving ring 4.

[0022] The side wall of the annular component 1 has several cavities 2. Several connecting rods 6 are fixedly connected to the inner side of the movable ring 4. Each connecting rod 6 corresponds to one cavity 2. The inner end of the connecting rod 6 is pulled out and extended into the cavity 2, and is fixedly connected to an abutment block 7.

[0023] The side wall of the annular component 1 is provided with several sealing plates 8. The inner side of the sealing plate 8 is fixedly connected to a fixing block 10. The other end of the fixing block 10 is fixedly connected to an elastic ball 11 that is compatible with the contact block 7.

[0024] When the sealing gasket 5 is compressed, it can drive the moving ring 4 to slide inside the receiving groove 3. By utilizing the connection between the two connecting rods 6, the two abutting blocks 7 can compress the elastic ball 11 to deform and generate elastic force. The elastic force of the elastic ball 11 reacts to the two connecting rods 6, thereby buffering the sealing gasket 5 when it is compressed, preventing the sealing gasket 5 from deforming due to excessive pressure, and improving the stability of the sealing process.

[0025] The sealing plate 8 can be disassembled from the surface of the annular part 1, which facilitates the removal and maintenance of the elastic ball 11. The prefabricated structure improves the convenience of later maintenance operations, and some components can be replaced individually when they are severely worn, reducing the maintenance cost of the rubber sealing gasket.

After turning the bolts 9 to remove them from the inside of the threaded holes 13, the sealing plate 8 can be disassembled. Through the connection of the fixing block 10, the elastic ball 11 can be taken out from between the two abutting blocks 7.

[0027] A handle 12 is fixedly connected to the outer side of the sealing plate 8. After the sealing plate 8 is removed, the handle 12 makes it easy for staff to pick it up.

[0028] The surface of the contact block 7 is provided with a bevel 16 that is compatible with the elastic ball 11. The bevel 16 facilitates the smooth insertion of the elastic ball 11 between the two sealing plates 8 for buffering during the later assembly process.

[0029] A sliding ring 14 is fixedly connected to the side wall of the moving ring 4, and a sliding groove 15 is provided inside the receiving groove 3 for the sliding ring 14 to move.

[0030] There are four cavities 2, which are evenly spaced and distributed along the side wall of the annular component 1.

[0031] The working principle of the novel rubber sealing gasket based on the thermo-pressed connection structure provided by this utility model is as follows:

[0032] When the sealing gasket 5 is compressed, it can drive the moving ring 4 to slide inside the receiving groove 3. By using the connection between the two connecting rods 6, the two abutting blocks 7 can compress the elastic ball 11 to deform and generate elastic force. The elastic force of the elastic ball 11 reacts to the two connecting rods 6, thereby buffering the sealing gasket 5 when it is compressed, avoiding the sealing gasket 5 from deforming due to excessive pressure, improving the stability of the sealing process, and the sealing plate 8 can be disassembled from the surface of the ring part 1, which is convenient for removing the elastic ball 11 for inspection and maintenance.
