Description

Technical Field

[0001] The utility model relates to the technical field of gasket sealing, and more specifically, to a sealing film structure of a mechanical device. Background Technique

[0002] There are various types of mechanical devices. When a mechanical device is operating, some of its components or even the device itself can perform different forms of mechanical movement. In order to prevent the leakage of liquids and gases during the operation of the device, a certain number of sealing films are more or less installed on the mechanical device.

[0003] Currently, the sealing film on a mechanical device is usually cylindrical in shape with a hollow interior. The overall thickness of the product is relatively uniform. When installed on a mechanical device, it plays a sealing role through the elasticity of the peripheral silicone. The structure is simple. However, only relying on the elasticity of the peripheral silicone for sealing will cause the sealing film to only be able to perform overall regional sealing during use, with a single sealing area, a single pressure-bearing capacity, and a small scope of application. Summary of the Utility Model

[0004] 1. Technical Problems to be Solved

[0005] Aiming at the problems existing in the prior art, the purpose of the present utility model is to provide a sealing film structure of a mechanical device, aiming to solve the problem that only relying on the elasticity of the peripheral silicone for sealing in the prior art will cause the sealing film to only be able to perform overall regional sealing during use, with a single sealing area, a single pressure-bearing capacity, and a small scope of application.

[0006] 2. Technical Solutions

[0007] To solve the above problems, the present utility model adopts the following technical solutions:

[0008] A sealing film structure of a mechanical device includes a film main body. A first rib position is provided at the top of the film main body. A second rib position is provided on the circumferential inner wall of the film main body, and the second rib position is located below the first rib position. The bottom wall of the film main body is sequentially provided with a third rib position, a fourth rib position, and a fifth rib position from outside to inside, and the third rib position, the fourth rib position, and the fifth rib position are all located below the sealing boss. Sealing bosses are provided at the tops of the first rib position, the second rib position, the third rib position, the fourth rib position, and the fifth rib position.

[0009] As a preferred solution of the present utility model, the diameters of the first rib position, the second rib position, the third rib position, the fourth rib position, and the fifth rib position decrease in sequence.

[0012] Compared with the prior art, the advantages of the present utility model are as follows:

[0013] (1) In this solution, the membrane body is provided with a plurality of first rib positions, second rib positions, third rib positions, fourth rib positions and fifth rib positions distributed in a diffusion manner at multiple locations, so that a plurality of sealing areas are formed during sealing compression. Each sealing area is sealed and separated by a sealing boss, which not only has a stable structure but also forms an effect of gradually strengthening the seal, and the bearing pressure of different areas can be controlled separately, with a wide range of applicable bearing pressures.

[0021] Embodiment:

[0022] Please refer to Figure 1-2 , a sealing film structure of a mechanical device, including a film body 1. A first rib position 2 is provided at the top of the film body 1. A second rib position 3 is provided on the circumferential inner wall of the film body 1, and the second rib position 3 is located below the first rib position 2. The bottom wall of the film body 1 is sequentially provided with a third rib position 4, a fourth rib position 5, and a fifth rib position 6 from outside to inside, and the third rib position 4, the fourth rib position 5, and the fifth rib position 6 are all located below the sealing boss 7. Sealing bosses 7 are provided at the tops of the first rib position 2, the second rib position 3, the third rib position 4, the fourth rib position 5, and the fifth rib position 6.

[0023] In this embodiment, the film body 1 is installed on the mechanical device. When the mechanical device is sealed, the film body 1 is squeezed. The film body 1 seals the mechanical device through its own elasticity. At the same time, after being squeezed, the film body 1 deforms, and multiple sealing areas are formed inside through the first rib position 2, the second rib position 3, the third rib position 4, the fourth rib position 5, and the fifth rib position 6. Multiple sealing bosses 7 contact the mechanical device to enhance the sealing effect.

[0024] Specifically, the diameters of the first rib position 2, the second rib position 3, the third rib position 4, the fourth rib position 5, and the fifth rib position 6 decrease in sequence.

[0025] In this embodiment, the first rib position 2, the second rib position 3, the third rib position 4, the fourth rib position 5, and the fifth rib position 6 are designed in a diffused manner, separating the single sealing area in the film body 1 into multiple areas to improve the sealing effect.

[0026] Specifically, multiple sealing bosses 7 are all made of silica gel material.

[0027] In this embodiment, multiple sealing bosses 7 follow the diffused design of the first rib position 2, the second rib position 3, the third rib position 4, the fourth rib position 5, and the fifth rib position 6. While the structure is stable, it also forms a gradually enhanced sealing effect.

[0028] Working principle: The membrane body 1 is installed on mechanical equipment. When the mechanical equipment performs sealing, the membrane body 1 is deformed by extrusion. The membrane body 1 seals the mechanical equipment through its own elasticity. Multiple sealing areas are formed inside the membrane body 1 through the first rib position 2, the second rib position 3, the third rib position 4, the fourth rib position 5 and the fifth rib position 6. Multiple sealing bosses 7 contact the mechanical equipment to separate the multiple sealing areas, resulting in a better sealing effect and a greater pressure-bearing capacity.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and its improved concept of the present invention, making equivalent replacements or changes should be covered within the protection scope of the present invention.
