Description

Technical Field

[0001] The utility model relates to the technical field of sealing rubber gaskets, and particularly relates to a dust-proof sealing rubber gasket. Background Technique

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under very small external forces, and can return to its original state after removing the external forces. Rubber belongs to a completely amorphous polymer. Its glass transition temperature is low, and its molecular weight is often very large, greater than several hundred thousand. Early rubber was taken from the latex of rubber trees, rubber grasses and other plants, and after processing, it was made into a material with elasticity, insulation, impermeability to water and air.

[0003] For example, the utility model with the publication number CN219606019U discloses a sealing rubber gasket, including a rubber gasket. An installation groove is opened on the upper surface of the rubber gasket. A compression ring is movably connected inside the installation groove. Compression blocks are fixedly connected to the surface of the compression ring. Compression grooves are opened on the inner wall of the rubber gasket. Sliding grooves are opened on the surface of the compression blocks. By providing the installation groove and the compression groove, the utility model is beneficial to installing the compression ring and the compression blocks on the inner wall of the rubber gasket, thereby improving the overall compression resistance of the rubber gasket, preventing the rubber gasket from being deformed and unable to recover due to long-term extrusion, and even cracking. Through the fitting action between the limit posts and the fitting grooves, the positions of the compression ring and the compression blocks on the inner wall of the rubber gasket can be restricted. By moving the limit mechanism, the limit posts are separated from the inside of the fitting grooves, and the compression ring and the compression blocks on the inner wall of the rubber gasket can be replaced and repaired.

[0004] In the process of implementing the present application, it is found that this technology has the following problems: Most existing sealing rubber gaskets prevent the rubber gasket from being deformed and unable to recover due to long-term extrusion by providing installation grooves and compression grooves. However, there are gaps between most rubber gaskets and connectors, making it easy for dust to enter the inside of the connector along the connection between the rubber gasket and the connector, thus reducing the practicability of the device.

[0005] Therefore, a dust-proof sealing rubber gasket is proposed. Content of the Utility Model

[0006] The purpose of the present utility model is to solve the problem that there are gaps between most rubber gaskets and connectors, making it easy for dust to enter the inside of the connector along the connection between the rubber gasket and the connector. The present utility model provides a dust-proof sealing rubber gasket.

[0007] The present utility model specifically adopts the following technical solutions to achieve the above purpose:

[0008] A dust-proof sealing rubber gasket includes two groups of rubber gasket bodies. Grooves are provided on one side of the two adjacent rubber gasket bodies. A sealing mechanism for sealing adjacent connecting parts is installed inside the grooves of the two rubber gasket bodies, and the upper and lower ends of the sealing mechanism are respectively installed inside the grooves of the rubber gasket bodies.

[0009] Further, the sealing mechanism includes two groups of annular fixing plates, which are respectively clamped inside the grooves of the two rubber gasket bodies. Two sealing air bags are installed on the upper surface of the bottom annular fixing plate, and the upper surfaces of the two sealing air bags are installed on the lower surface of the top annular fixing plate. A spring telescopic rod is provided on the upper surface of the bottom annular fixing plate, and the upper surface of the spring telescopic rod is installed on the lower surface of the top annular fixing plate. Connecting blocks are installed on the outer surfaces of both sides of the top of the spring telescopic rod. Pistons rods are provided on the lower surfaces of the two connecting blocks. Two annular air bags are provided on the upper surface of the bottom annular fixing plate, and cylinders are installed on the upper surfaces of the two annular air bags. The two piston rods are respectively inserted into the two cylinders, and the opposite sides of the two annular air bags are respectively attached to the adjacent sides of the two sealing air bags.

[0010] Further, two limiting rings are installed on the upper surface of the bottom annular fixing plate, and the opposite sides of the two limiting rings are respectively abutted against the adjacent sides of the two annular air bags.

[0011] Further, limiting plates are installed on the left and right sides of the bottom of the spring telescopic rod, through holes are provided on the upper surfaces of the two limiting plates, and the tops of the two cylinders respectively pass through the through holes of the two limiting plates.

[0012] Further, silicone gaskets are bonded to the opposite sides of the two sealing air bags.

[0013] Further, positioning grooves are provided on the opposite sides of the two rubber gasket bodies, and fixing rings are installed inside the positioning grooves of the two rubber gasket bodies.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. The utility model squeezes two groups of rubber gasket bodies through two groups of connecting pieces, so that the top of the spring telescopic rod drives two groups of connecting blocks and two groups of piston rods to move downward. Then, the two groups of piston rods are inserted into the two groups of cylinders. When the two groups of piston rods are pressed downward, the two groups of annular air bags are inflated to push the outer surfaces of the two groups of sealing air bags to move toward one side of the inner wall of the connecting piece. Thus, the two groups of sealing air bags seal the space between the two groups of rubber gasket bodies and the inner wall of the connecting piece, thereby improving the sealing performance of the rubber gasket during use and enhancing its dust-proof performance.

[0016] 2. The utility model inserts two groups of cylinders into the through holes of two groups of limit plates, so that the two groups of limit plates limit the moving positions of the two groups of cylinders, thus minimizing the change in the positions of the two groups of cylinders during the subsequent up-and-down movement of the two groups of piston rods, which may otherwise cause the two groups of piston rods to be unable to be inserted into the two groups of cylinders during use. Therefore, the stability of the sealing mechanism during use is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] As Figures 1 to 4 shown, a dust-proof sealing rubber gasket includes two groups of rubber gasket bodies 1. Grooves are formed on one side of each of the two adjacent rubber gasket bodies 1. A sealing mechanism 4 for sealing adjacent connecting members is installed inside the grooves of the two groups of rubber gasket bodies 1. The upper and lower ends of the sealing mechanism 4 are respectively installed inside the grooves of the rubber gasket bodies 1. Specifically, by squeezing the two groups of rubber gasket bodies 1, the inner walls on the left and right sides of the sealing mechanism 4 are propped up, so that the inner walls on the left and right sides of the sealing mechanism 4 are attached to the inner wall of the connecting member, and further the sealing mechanism 4 seals the space between the two groups of rubber gasket bodies 1 and the inner wall of the connecting member, thereby improving the sealing performance of the rubber gasket during use, and thus improving the dust-proof performance of the rubber gasket.

[0027] As Figures 1 to 4As shown, the sealing mechanism 4 includes two sets of annular fixing plates 402. The two sets of annular fixing plates 402 are respectively clamped inside the grooves of the two rubber gasket bodies 1. Two sealing air bags 401 are installed on the upper surface of the lower set of annular fixing plates 402. The upper surfaces of the two sealing air bags 401 are both installed on the lower surface of the upper set of annular fixing plates 402. A spring telescopic rod 404 is arranged on the upper surface of the lower set of annular fixing plates 402. The upper surface of the spring telescopic rod 404 is installed on the lower surface of the upper set of annular fixing plates 402. Connecting blocks 405 are installed on the outer surfaces of both sides of the top end of the spring telescopic rod 404. Piston rods 406 are arranged on the lower surfaces of the two connecting blocks 405. Two annular air bags 403 are arranged on the upper surface of the lower set of annular fixing plates 402. Cylinders 407 are installed on the upper surfaces of the two annular air bags 403. The two piston rods 406 are respectively inserted into the two cylinders 407. The opposite sides of the two annular air bags 403 are respectively attached to the adjacent sides of the two sealing air bags 401;

[0028] Specifically, when the two rubber gasket bodies 1 are installed inside the connector, the two connectors squeeze the two rubber gasket bodies 1, so that the top end of the spring telescopic rod 404 drives the two connecting blocks 405 and the two piston rods 406 to move downward. Then, the two piston rods 406 are inserted into the two cylinders 407, so that the two annular air bags 403 are propped up during the downward pressing process to push the outer surfaces of the two sealing air bags 401 to move toward the inner wall of the connector, thereby making the two sealing air bags 401 seal the space between the two rubber gasket bodies 1 and the inner wall of the connector, thus improving the sealing performance of the rubber gasket during use, and therefore improving the dust-proof performance of the rubber gasket.

[0029] At the same time, due to the elastic potential energy of the spring telescopic rod 404, when the two connectors are disconnected, the spring telescopic rod 404 pushes the two rubber gasket bodies 1 to drive the two sealing air bags 401 to reset, so that the two sealing air bags 401 can automatically disconnect from the inner wall of the connector, thus reducing the time and labor consumed by the subsequent staff when disassembling and moving the sealing gasket.

[0030] Such as Figure 4As shown, on the upper surface of a set of annular fixing plates 402 at the bottom end, two sets of limiting rings 5 are installed, and the opposite sides of the two sets of limiting rings 5 are respectively abutted against the adjacent sides of the two sets of annular air bags 403; specifically, by abutting the opposite sides of the two sets of limiting rings 5 against the adjacent sides of the two sets of annular air bags 403, the two sets of limiting rings 5 limit the movement paths of the two sets of annular air bags 403 during inflation, so that the two sets of annular air bags 403 can quickly push the two sets of sealing air bags 401 towards the connection of the connecting piece during subsequent use, thereby shortening the time consumed by the subsequent sealing mechanism 4 when sealing the connection between the rubber gasket and the connecting piece.

[0031] As Figure 4 shown, on the left and right sides of the bottom end of the spring telescopic rod 404, two limiting plates 6 are installed, and through holes are opened on the upper surfaces of the two limiting plates 6, and the top ends of the two cylinders 407 are respectively inserted into the through holes of the two limiting plates 6; specifically, by inserting the two cylinders 407 into the through holes of the two limiting plates 6, the two limiting plates 6 limit the moving positions of the two cylinders 407, so as to avoid as much as possible the positions of the two cylinders 407 changing during the up and down movement of the two piston rods 406, resulting in the two piston rods 406 being unable to be inserted into the two cylinders 407 during subsequent use. Therefore, the stability of the sealing mechanism 4 during use is improved.

[0032] As Figure 1 and Figure 3 shown, on the opposite sides of the two sets of sealing air bags 401, two silicone gaskets 3 are bonded; specifically, by arranging the two silicone gaskets 3 between the two sets of sealing air bags 401 and the connecting piece, the two silicone gaskets 3 shield and protect the outer surfaces of the two sets of sealing air bags 401 exposed during use, so as to avoid as much as possible the two sets of sealing air bags 401 coming into contact with the medium flowing on the outer surface of the connecting piece during use, resulting in the two sets of sealing air bags 401 being corroded. Therefore, the service life of the two sets of sealing air bags 401 is improved; due to the good corrosion resistance of silicone, the two sets of sealing air bags 401 are not easily corroded by the flowing medium during long-term use, thereby reducing the frequency of the staff regularly replacing and maintaining the sealing air bags 401.

[0033] As Figure 1As shown, positioning grooves are provided on opposite sides of the two rubber gasket bodies 1, and fixing rings 2 are installed inside the positioning grooves of the two rubber gasket bodies 1; specifically, the force-bearing strength of the cross-sections of the two rubber gasket bodies 1 is increased by the two fixing rings 2, so that the two rubber gasket bodies 1 are not easily bent when subjected to lateral extrusion during use, thus minimizing the synchronous deformation of the sealing mechanism 4 driven by the two rubber gasket bodies 1 during bending, resulting in damage to the sealing mechanism 4 during use. Therefore, the service life of this sealing rubber gasket is extended.

[0034] In summary: The two rubber gasket bodies 1 are extruded by the two connecting members, causing the top of the spring telescopic rod 404 to drive the two connecting blocks 405 and the two piston rods 406 to move downward. Then, the two piston rods 406 are inserted into the two cylinders 407. During the downward pressing process of the two piston rods 406, the two annular airbags 403 expand and push the outer surfaces of the two sealing airbags 401 to move toward the inner wall side of the connecting member, thereby enabling the two sealing airbags 401 to seal the space between the two rubber gasket bodies 1 and the inner wall of the connecting member, thus improving the sealing performance of this rubber gasket during use; due to the elastic potential energy of the spring telescopic rod 404, when the two connecting members are disconnected, the spring telescopic rod 404 pushes the two rubber gasket bodies 1 to drive the two sealing airbags 401 to reset, so that the two sealing airbags 401 can automatically disconnect from the inner wall of the connecting member, thereby reducing the time and labor consumed by subsequent workers when disassembling and moving this sealing gasket.

[0035] Meanwhile, the force-bearing strength of the cross-sections of the two rubber gasket bodies 1 is increased by the two fixing rings 2, so that the two rubber gasket bodies 1 are not easily bent when subjected to lateral extrusion during use, thus minimizing the synchronous deformation of the sealing mechanism 4 driven by the two rubber gasket bodies 1 during bending, resulting in damage to the sealing mechanism 4 during use.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
