[0004] However, when existing foamed silicone gaskets are stacked, there is no limiting structure between multiple gaskets, which may cause individual gaskets to slip off, thus affecting the overall sealing effect of the foamed silicone gaskets. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an oil-resistant foamed silicone sealing gasket structure, which solves the problem that when existing foamed silicone sealing gaskets are stacked, individual sealing gaskets may slip off due to the lack of a limiting structure between multiple gaskets, thus affecting the overall sealing effect of the foamed silicone sealing gasket.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oil-resistant foamed silicone sealing gasket structure, comprising a sealing gasket, wherein a limiting mechanism is provided on the outer wall of the sealing gasket, the limiting mechanism comprising: two grooves, both located on the top of the sealing gasket; two protrusions, both fixedly connected to the side of the sealing gasket away from the grooves; and an auxiliary component disposed on the outer wall of the sealing gasket; wherein, driven by the sealing gasket, two of the protrusions are inserted into the grooves on the surface of another sealing gasket to limit the multiple sealing gaskets, and the auxiliary component enables the multiple sealing gaskets to fit tightly together.

[0007] Preferably, the auxiliary component includes: a first annular ring fixedly connected to the sealing gasket on the other side near the groove; and a second annular ring fixedly connected to the sealing gasket on the side near the protrusion; wherein, through the cooperation between the first annular ring and the second annular ring, the first annular ring and the second annular ring are tightly attached to the upper and lower sealing gaskets, so that the multiple sealing gaskets are tightly attached together.

[0011] Beneficial effects

[0012] This utility model provides an oil-resistant foamed silicone sealing gasket structure. It has the following advantages: This oil-resistant foamed silicone sealing gasket structure, through the cooperation of grooves, protrusions, and convex strips, effectively limits the positioning of multiple sealing gaskets, preventing them from slipping off. This solves the problem that existing foamed silicone sealing gaskets, when stacked, may experience individual gaskets slipping off due to the lack of a limiting structure between multiple gaskets, thus affecting the overall sealing effect of the foamed silicone sealing gasket.

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] When existing foamed silicone gaskets are stacked, some gaskets may slip off due to the lack of any limiting structure between them, thus affecting the overall sealing effect of the foamed silicone gaskets.

[0020] In view of this, the present invention provides an oil-resistant foamed silicone sealing gasket structure. Through the cooperation between grooves, protrusions and ridges, multiple sealing gaskets are limited to prevent them from slipping off. This solves the problem that when existing foamed silicone sealing gaskets are stacked, individual sealing gaskets may slip off due to the lack of a limiting structure between multiple sealing gaskets, thus affecting the overall sealing effect of the foamed silicone sealing gasket.

[0021] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly introduced below.

[0022] Example 1, by Figure 1 and 3 As can be seen, the oil-resistant foamed silicone sealing gasket structure in this case includes a sealing gasket 1, which is circular in shape and has a through hole in the middle. A limiting mechanism 2 is provided on the outer wall of the sealing gasket 1. The limiting mechanism 2 includes two grooves 21, both located on the top of the sealing gasket 1. A corresponding protrusion 22 is inserted into the groove 21 on the top of another sealing gasket 1 to limit the movement of multiple sealing gaskets 1. The bottommost sealing gasket 1 does not have a protrusion 22, and the topmost sealing gasket 1 does not have a groove 22. 1. There are two protruding strips 22, and both are fixedly connected to the side of the sealing gasket 1 away from the groove 21. When the sealing gasket 1 is in use, the staff stacks multiple sealing gaskets 1 together. One of the sealing gaskets 1 drives the bottom protruding strip 22 to move. The auxiliary component 23 is set on the outer wall of the sealing gasket 1. Under the drive of the sealing gasket 1, the two protruding strips 22 are inserted into the groove 21 on the surface of the other sealing gasket 1 to limit the multiple sealing gaskets 1. Through the auxiliary component 23, the multiple sealing gaskets 1 are tightly fitted together.

[0023] In the specific implementation process, it is worth noting that the sealing gasket 1 is circular in shape and has a through hole in the middle. When the sealing gasket 1 is used, the staff stacks multiple sealing gaskets 1 together. One sealing gasket 1 moves the bottom protrusion 22, and the corresponding protrusion 22 is inserted into the groove 21 on the top of another sealing gasket 1 to limit the multiple sealing gaskets 1. The bottom sealing gasket 1 does not have a protrusion 22, and the top sealing gasket 1 does not have a groove 21 on the top, so as to limit the multiple sealing gaskets 1 and prevent the sealing gasket 1 from slipping.

[0024] Furthermore, the auxiliary component 23 includes: a first annular ring 231, fixedly connected to the other side of the sealing gasket 1 near the groove 21. When multiple sealing gaskets 1 are stacked, the first annular ring 231 and the second annular ring 232 on the upper and lower sides of the sealing gasket 1 respectively contact the surfaces of other sealing gaskets 1. The second annular ring 232 is fixedly connected to the side of the sealing gasket 1 near the protrusion 22. After the sealing gaskets 1 are installed, due to the compression force of multiple sealing gaskets 1, the first annular ring 231 and the second annular ring 232 are tightly attached to the other sealing gaskets 1. The surface of the sealing gasket 1 is improved to enhance the sealing performance of multiple sealing gaskets 1. The sealing gasket 1 in the middle position is provided with a first annular ring 231 and a second annular ring 232 at the top and bottom. The surfaces of the upper and lower sealing gaskets 1 are not provided with the first annular ring 231 and the second annular ring 232. The outer walls of the upper and lower sealing gaskets 1 are directly attached to the surface of the part. Through the cooperation between the first annular ring 231 and the second annular ring 232, the first annular ring 231 and the second annular ring 232 are tightly attached to the upper and lower sealing gaskets 1, so that the multiple sealing gaskets 1 are tightly attached together.

[0025] In the specific implementation process, it is worth noting that when multiple sealing gaskets 1 are stacked, the first annular ring 231 and the second annular ring 232 on the upper and lower sides of the sealing gasket 1 are in contact with the surfaces of other sealing gaskets 1. After the sealing gaskets 1 are installed, due to the compression force of multiple sealing gaskets 1, the first annular ring 231 and the second annular ring 232 are tightly attached to the surfaces of other sealing gaskets 1, thereby improving the sealing performance of multiple sealing gaskets 1. The sealing gasket 1 in the middle position is provided with the first annular ring 231 and the second annular ring 232 on the upper and lower sides, while the surfaces of the upper and lower sealing gaskets 1 are not provided with the first annular ring 231 and the second annular ring 232. The outer walls of the upper and lower sealing gaskets 1 are directly attached to the surface of the part, thereby achieving a tight fit between multiple sealing gaskets 1.

[0026] Furthermore, the outer wall of the sealing gasket 1 is fixedly connected with a protrusion 211. The number of protrusions 211 is set to several. When the operator moves the sealing gasket 1, the sealing gasket 1 drives the protrusions 211 to move. The protrusions 211 are inserted into the insertion holes on the inner wall of the part, thereby further limiting the position between multiple sealing gaskets 1.

[0027] In the specific implementation process, it is worth noting that the number of protrusions 211 is set to several. When the staff moves the sealing gasket 1, the sealing gasket 1 drives the protrusions 211 to move. The protrusions 211 are inserted into the insertion holes on the inner wall of the part, thereby further limiting the position between the multiple sealing gaskets 1.

[0028] Specifically, when using the sealing gasket 1, the worker stacks multiple sealing gaskets 1 together. One sealing gasket 1 moves the bottom protrusion 22, and the corresponding protrusion 22 inserts into the groove 21 on the top of another sealing gasket 1. The sealing gasket 1 moves the protrusion 211, and the protrusion 211 inserts into the insertion hole on the inner wall of the part to limit the multiple sealing gaskets 1. At the same time, when multiple sealing gaskets 1 are stacked, the first annular ring 231 and the second annular ring 232 on the upper and lower sides of the sealing gasket 1 respectively contact the surface of other sealing gaskets 1. After the sealing gaskets 1 are installed, due to the squeezing force of multiple sealing gaskets 1, the first annular ring 231 and the second annular ring 232 are tightly attached to the surface of other sealing gaskets 1, so that the multiple sealing gaskets 1 are tightly attached together.

[0029] Example 2, by Figure 1 and 2 It can be seen that the outer wall of the sealing gasket 1 is fixedly connected with an oil-resistant layer 11;

[0030] In the specific implementation process, it is worth noting that the material of the oil-resistant layer 11 is fluororubber, which is a high-performance elastomer with high chemical stability and excellent oil and high temperature resistance. It can maintain its excellent performance in a temperature range of -20℃ to 300℃, and can also resist the erosion of chemicals such as acids, alkalis, and solvents, thereby improving the overall oil resistance of the sealing gasket 1;

[0031] Furthermore, a wear-resistant layer 12 is fixedly connected to the outer wall of the oil-resistant layer 11. The wear-resistant layer 12 is made of nylon, which is a high-toughness material with good wear resistance, corrosion resistance and temperature resistance, thus achieving the wear resistance effect of the sealing gasket 1.

[0032] In the specific implementation process, it is worth noting that the material of the wear-resistant layer 12 is nylon. Nylon is a high-toughness material with good wear resistance, corrosion resistance and temperature resistance, so as to achieve the wear resistance effect of the sealing gasket 1.

[0033] Specifically, the oil-resistant layer 11 is made of fluororubber, a high-performance elastomer with high chemical stability and excellent oil and high-temperature resistance. It can maintain its excellent performance in a temperature range of -20℃ to 300℃, and can also resist the erosion of chemicals such as acids, alkalis, and solvents, thus improving the overall oil resistance of the sealing gasket 1. The wear-resistant layer 12 is made of nylon, a high-toughness material with good wear resistance, corrosion resistance, and temperature resistance, achieving the wear resistance effect of the sealing gasket 1.
