Description

Technical Field

[0001] The utility model relates to the technical field of rubber rings, in particular to an oil-resistant sealing rubber ring. Background Art

[0002] A rubber sealing ring is generally an annular ring composed of one or more parts, which is used to be fixed at the end of a pipe fitting and connected to the end of another pipe fitting to form a seal to prevent the medium inside the pipe fitting, such as lubricating oil, from leaking out and to prevent foreign objects from invading the pipe. However, when the existing sealing rubber ring is used, it will be damaged and its durability will be reduced due to long-term contact with oil, and the strength of the rubber will be reduced after long-term extrusion, thereby affecting the sealing performance. Therefore, those skilled in the art provide an oil-resistant sealing rubber ring to solve the problems raised in the above background technology. Utility Model Content

[0003] The utility model aims to provide an oil-resistant sealing rubber ring to solve the problems raised in the above-mentioned background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] An oil-resistant sealing rubber ring comprises a sealing ring body, wherein an anti-deformation structure is arranged inside the sealing ring body;

[0006] The anti-deformation structure comprises a connecting frame, the connecting frame is located inside the sealing ring body, an inner frame is fixedly connected to the inner side of the connecting frame, and an outer frame is fixedly connected to the outer side of the connecting frame.

[0007] As a further solution of the utility model: the upper and lower surfaces of the sealing ring body are respectively provided with installation grooves.

[0008] As a further solution of the utility model: the inner frame and the outer frame are located at the inner and outer sides of the installation slot, and the connecting frame is located between the upper and lower installation slots.

[0009] As a further solution of the utility model: an inner groove is provided in the middle of the inner wall of the sealing ring body.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] By arranging an inner frame and an outer frame inside the sealing ring body and connecting the inner frame and the outer frame through a connecting frame, the inner frame and the outer frame can be stretched to prevent the inner frame and the outer frame from changing position following the deformation of the sealing ring body, which can enhance the sealing ring's anti-deformation ability and thereby increase the strength of the sealing ring. The connecting frame separates the two mounting slots to prevent the pipes from squeezing each other and causing the two mounting slots to penetrate each other. An inner groove is provided in the middle of the inner wall of the sealing ring body so that the inner diameters of the two ends of the inner wall of the sealing ring body are the smallest and the pressure there is the largest. The inner diameter in the middle is the largest and the pressure there is the smallest. This allows the two ends of the sealing ring body located on the inner side of the pipe to fit closer to the inner wall of the pipe, thereby further enhancing the penetration of the oil agent and ensuring the sealing effect.

[0016] See also Figures 1 to 3 In the embodiment of the utility model, an oil-resistant sealing rubber ring includes a sealing ring body 1, an anti-deformation structure is arranged inside the sealing ring body 1, and the anti-deformation structure includes a connecting skeleton 5, the connecting skeleton 5 is located inside the sealing ring body 1, an inner skeleton 4 is fixedly connected to the inner side of the connecting skeleton 5, and an outer skeleton 6 is fixedly connected to the outer side of the connecting skeleton 5, and the three skeletons can be made of hard plastic material or highly elastic metal material, such as copper sheet, and the skeleton and rubber are made by vulcanization process.

[0017] Preferably, mounting grooves 2 are respectively provided on the upper and lower surfaces of the sealing ring body 1 .

[0018] Preferably, the inner skeleton 4 and the outer skeleton 6 are located on the inner and outer sides of the mounting slot 2, and the connecting skeleton 5 is located between the upper and lower mounting slots 2. The end of the pipe fitting is clamped into the inside of the mounting slot 2. At this time, the inner skeleton 4 and the outer skeleton 6 are located on the inner and outer sides of the end of the pipe fitting. The hardness of the inner skeleton 4 and the outer skeleton 6 can be used to clamp the end of the pipe fitting to form a seal, and the connecting skeleton 5 is used to separate the two mounting slots 2. When two mounting slots 2 are respectively installed with two pipe fittings, the pipe fittings can be prevented from being squeezed against each other and causing the two mounting slots 2 to penetrate each other.

[0019] Preferably, an inner groove 3 is provided in the middle of the inner wall of the sealing ring body 1. When the rubber ring is installed on the end of the pipe fitting, when the medium inside the pipe fitting flows to the inner wall of the sealing ring body 1, pressure will be generated on the inner wall. Since the inner groove 3 is provided in the middle of the inner wall of the sealing ring body 1, the pressure on the two ends of the inner wall of the sealing ring body 1 is greater at this time, and the pressure in the middle is the smallest. This allows the two ends of the sealing ring body 1 located on the inner side of the pipe fitting to fit closer to the inner wall of the pipe fitting, thereby further enhancing the penetration of the oil agent and ensuring the sealing effect.

[0020] The working principle of the utility model is as follows: by arranging an inner frame and an outer frame inside the sealing ring body, when the end of the pipe is clamped to the inside of the mounting slot 2, the inner frame 4 and the outer frame 6 are located inside and outside the end of the pipe, and the hardness of the inner frame 4 and the outer frame 6 can be used to clamp the end of the pipe to form a seal, and a connecting frame 5 is provided to connect the inner frame 4 and the outer frame 6, and the inner frame 4 and the outer frame 6 can be stretched to prevent the inner frame 4 and the outer frame 6 from changing position with the deformation of the sealing ring body 1, thereby further enhancing the anti-deformation ability of the sealing ring, and the connecting frame 5 separates the two mounting slots 2 When two pipe fittings are installed in the two mounting grooves 2 respectively, the pipe fittings can be prevented from being squeezed against each other and penetrating each other. An inner groove 3 is provided in the middle of the inner wall of the sealing ring body 1. After the medium in the pipe fitting flows to the inner wall of the sealing ring body 1, pressure is formed on the inner wall. Since the inner groove 3 is provided in the middle of the inner wall of the sealing ring body 1, the inner diameters of the two ends of the inner wall of the sealing ring body 1 are smaller at this time, and the pressure is the largest. The inner diameter in the middle is the largest and the pressure is the smallest. This allows the two ends of the sealing ring body 1 located on the inner side of the pipe fitting to fit closer to the inner wall of the pipe fitting, thereby further enhancing the penetration of the oil agent and ensuring the sealing effect.

[0021] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
