[0002] A rubber sealing ring is an annular cover composed of one or several parts, which is fixed on one race or washer of a bearing and contacts or forms a narrow labyrinth gap with another race or washer to prevent lubricating oil from leaking out and foreign objects from invading. The rubber sealing ring is used for installation on various mechanical equipment and plays a sealing role in a static or moving state under specified temperature, pressure, and different liquids and gases.

[0003] After retrieval, Chinese Patent No. CN219345472U discloses a fluororubber sealing ring, including a first ring body and a second ring body that are in contact and connected with each other. The characteristics are as follows: a first solid block is fixedly connected to one side of the first ring body, a first hollow block is fixedly connected to one side of the first solid block, first grooves are arranged on both sides of the first solid block, two second solid blocks are fixedly connected to one side of the second ring body, the first hollow block is located between the two second solid blocks, and second grooves are formed on the opposite sides of the two second solid blocks facing each other. In this utility model, by arranging the first solid block, the first hollow block, the second solid block, and the second hollow block in the fluororubber sealing ring, the deformation caused by the mutual extrusion of the two fluororubber sealing rings is increased, so as to increase the contact area between the two fluororubber sealing rings and improve the sealing performance between the two fluororubber sealing rings.

[0004] However, the above patent has the following problems:

[0005] Although the contact area between the two fluororubber sealing rings is increased through the arrangement of structures such as the first solid block and the first hollow block, and the sealing performance between the two fluororubber sealing rings is improved accordingly, when assembling the rubber sealing ring, it is impossible to quickly distinguish the front and back of the rubber sealing ring, which makes it inconvenient to assemble the rubber sealing ring and impossible to quickly assemble the rubber sealing ring, thus reducing the assembly efficiency of the rubber sealing ring. Therefore, an assembly structure of a nitrile rubber sealing ring is proposed. Content of the Utility Model

[0006] The purpose of the utility model is to provide an assembly structure of a nitrile rubber sealing ring, which solves the problem that the existing assembly structure of a nitrile rubber sealing ring cannot quickly distinguish the front and back of the rubber sealing ring during use and cannot quickly assemble the rubber sealing ring, thus reducing the assembly efficiency of the rubber sealing ring.

[0007] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model relates to an assembly structure of a nitrile rubber sealing ring, which includes a lower mounting seat, an upper mounting seat, and a rubber sealing ring installed on the surface of the lower mounting seat. The lower surface of the rubber sealing ring is fixedly connected with rubber hollow tubes in a circular array. The upper surface of the rubber sealing ring is fixedly connected with a rubber hollow ring. The surface of the rubber sealing ring is provided with communication grooves in a circular array. The surface of the rubber hollow ring is provided with an air cavity, and the air cavity corresponds to the communication grooves. The inside of the rubber hollow ring is fixedly connected with rubber pressing blocks in a path array.

[0009] Further, a circular groove is provided on the surface of the lower mounting seat, and insertion grooves are provided on the inner bottom wall of the circular groove in a circular array.

[0010] Further, a plurality of the rubber hollow tubes respectively correspond to a plurality of the insertion grooves, and the rubber sealing ring corresponds to the circular groove.

[0011] Further, the rubber hollow ring is communicated with the rubber hollow tubes through the communication grooves, and a wear-resistant ring is fixedly connected to the surface of the rubber sealing ring.

[0012] Further, the material of the rubber sealing ring is nitrile rubber.

[0013] Further, the upper mounting seat is threadedly connected with the lower mounting seat, and the upper mounting seat corresponds to the rubber sealing ring.

[0014] Further, the upper mounting seat is communicated with the lower mounting seat, and the upper mounting seat is communicated with the rubber hollow ring.

[0015] The utility model has the following beneficial effects:

[0016] Through the setting of structures such as the rubber sealing ring, rubber hollow tubes, rubber hollow ring, rubber pressing blocks, and communication grooves, the rubber hollow tubes are inserted into the insertion grooves, so that the rubber sealing ring is installed inside the circular groove. Then, through the installation of the lower mounting seat and the upper mounting seat, the upper mounting seat squeezes the rubber hollow ring, so that the air in the air cavity enters the inside of the rubber hollow tubes through the communication grooves, causing the rubber hollow tubes to expand. Thus, the rubber hollow tubes are more stably installed with the insertion grooves, making the rubber sealing ring more stable during installation. And through the setting of the nitrile material, the oil resistance, wear resistance, heat resistance, and adhesion of the rubber sealing ring are enhanced. At the same time, through the setting of the rubber hollow tubes, it is easier to distinguish the front and back of the rubber sealing ring, making the assembly of the rubber sealing ring faster, improving the assembly efficiency of the rubber sealing ring, and solving the problems in the prior art that it is impossible to quickly distinguish the front and back of the rubber sealing ring and impossible to quickly assemble the rubber sealing ring, thus reducing the assembly efficiency of the rubber sealing ring.

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0028] Please refer to Figures 1 - 5 As shown, the utility model is a nitrile rubber seal ring assembly structure, including a lower mounting seat 1, an upper mounting seat 2, and a rubber seal ring 3 mounted on the surface of the lower mounting seat 1. The material of the rubber seal ring 3 is nitrile rubber. Through the setting of the nitrile material, the oil resistance, wear resistance, heat resistance, and adhesion of the rubber seal ring 3 are enhanced. The upper mounting seat 2 is threadedly connected to the lower mounting seat 1, and the upper mounting seat 2 corresponds to the rubber seal ring 3. A wear-resistant ring 7 is fixedly connected to the surface of the rubber seal ring 3. An annular groove 9 is formed on the surface of the lower mounting seat 1, and insertion grooves 10 are formed in an annular array on the inner bottom wall of the annular groove 9. Rubber hollow tubes 4 are fixedly connected to the lower surface of the rubber seal ring 3 in an annular array. Through the setting of the rubber hollow tubes 4, the front and back sides of the rubber seal ring 3 are easier to distinguish, thus avoiding the wrong installation direction when installing the rubber seal ring 3. A number of rubber hollow tubes 4 respectively correspond to a number of insertion grooves 10. The rubber hollow tubes 4 are inserted into the interior of the insertion grooves 10, so that the rubber seal ring 3 is installed inside the annular groove 9, and the rubber hollow ring 5 is synchronously installed on the lower mounting seat 1. The rubber seal ring 3 corresponds to the annular groove 9. A rubber hollow ring 5 is fixedly connected to the upper surface of the rubber seal ring 3. The upper mounting seat 2 communicates with the lower mounting seat 1, and the upper mounting seat 2 communicates with the rubber hollow ring 5. Communication grooves 6 are formed in an annular array on the surface of the rubber seal ring 3. The rubber hollow ring 5 communicates with the rubber hollow tubes 4 through the communication grooves 6. An air cavity 8 is formed on the surface of the rubber hollow ring 5. The upper mounting seat 2 is installed on the lower mounting seat 1, so that the upper mounting seat 2 presses the rubber hollow ring 5, and the air inside the air cavity 8 enters the interior of the rubber hollow tubes 4 through the communication grooves 6, causing the rubber hollow tubes 4 to expand, so that the rubber hollow tubes 4 are clamped inside the insertion grooves 10, making the installation of the rubber seal ring 3 more stable. The air cavity 8 corresponds to the communication grooves 6. By squeezing the rubber hollow ring 5, the rubber hollow ring 5 and the rubber seal ring 3 are deformed by extrusion, so that the rubber seal ring 3 seals the connection between the upper mounting seat 2 and the lower mounting seat 1. Rubber abutting blocks 11 are fixedly connected to the interior of the rubber hollow ring 5 in a path array. Through the setting of the rubber abutting blocks 11, the contact area between the rubber seal ring 3 and the rubber hollow ring 5 is increased, so that the rubber seal ring 3 and the rubber hollow ring 5 are more closely connected during use, and the sealing performance of the rubber seal ring 3 is increased.

[0029] Specifically, when the assembly structure of the nitrile rubber sealing ring is in use: through the setting of the rubber hollow tube 4, it is easier to distinguish the front and back sides of the rubber sealing ring 3, thus avoiding the reverse installation direction when installing the rubber sealing ring 3. Insert the rubber hollow tube 4 into the inside of the insertion groove 10, so that the rubber sealing ring 3 is installed inside the annular groove 9, and the rubber hollow ring 5 is synchronously installed on the lower mounting seat 1. Then install the upper mounting seat 2 on the lower mounting seat 1, so that the upper mounting seat 2 squeezes the rubber hollow ring 5, making the air in the air cavity 8 enter the inside of the rubber hollow tube 4 through the communication groove 6, causing the rubber hollow tube 4 to expand, and thus making the rubber hollow tube 4 clamped inside the insertion groove 10, making the installation of the rubber sealing ring 3 more stable. And through the extrusion of the rubber hollow ring 5, the rubber hollow ring 5 and the rubber sealing ring 3 are extruded and deformed, so that the rubber sealing ring 3 seals the connection between the upper mounting seat 2 and the lower mounting seat 1. And through the setting of the rubber pressing block 11, the contact area between the rubber sealing ring 3 and the rubber hollow ring 5 is increased, so that the rubber sealing ring 3 and the rubber hollow ring 5 are closer when in use, and the sealing performance of the rubber sealing ring 3 is increased.
