Description

Technical Field

[0001] This utility model relates to the field of rubber sealing ring technology, specifically an anti-detachment rubber sealing ring. Background Technology

[0002] A rubber seal is an annular cover consisting of one or more parts, fixed to one of the bearing rings or washers and in contact with or forming a narrow labyrinth gap with the other ring or washer to prevent lubricating oil leakage and foreign matter intrusion.

[0003] Existing rubber seals have the following problems:

[0004] To prevent detachment, most existing rubber sealing rings are embedded, but embedded anti-detachment structures are generally ineffective and inconvenient to install. Utility Model Content

[0005] The purpose of this invention is to provide an anti-detachment rubber sealing ring to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an anti-detachment rubber sealing ring, comprising a housing, an installation port on the housing, a sealing ring in the installation port, a positioning structure on the sealing ring, the positioning structure comprising a fixing ring, a fixing ring in the sealing ring, a connecting screw on the fixing ring, a pressure ring on the sealing ring, a mating interface on the pressure ring, and a nut connected to the connecting screw.

[0007] Preferably, the sealing ring is provided with an installation port two.

[0008] Preferably, the inner diameter of the pressure ring is larger than the inner diameter of the sealing ring.

[0009] Preferably, the fixing ring is provided with a connection port, and the pressure ring surface is provided with a connecting rod.

[0010] Preferably, at least two connecting rods are provided, and the number of connecting ports is the same as the number of connecting rods.

[0011] Preferably, the number of the mating interfaces is the same as the number of the connecting rods, and the positions of the connecting rods correspond to the mating interfaces.

[0012] Preferably, the fixing ring is provided with an extension plate, the connecting screw is fixed on the extension plate, the surface of the extension plate is provided with an extension portion, and the extension portion is embedded in the sealing ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Insert the sealing ring into mounting port one, then the connecting screw passes through the housing. Next, the extension plate rests against the surface of the housing, and then the pressure ring is placed into mounting port two. At this point, the interface is aligned with the connecting screw, and then the nut is threaded onto the connecting screw. Tighten the nut so that the pressure ring is pushed and locked onto the surface of the housing. The extension plate and the pressure ring together keep the sealing ring locked in mounting port one. The extension plate and the pressure ring clamped in the housing effectively prevent the sealing ring from being forced out of mounting port one, thus improving the anti-loosening effect. When the connecting rod is connected to the interface, it can prevent the pressure ring and the sealing ring from misaligning. Attached Figure Description

Detailed Implementation

[0021] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0022] Please see Figure 1 and Figure 2 This utility model provides an anti-detachment rubber sealing ring, including a housing 1, an installation port 2 on the housing 1, a sealing ring 3 in the installation port 2, and a positioning structure 4 on the sealing ring 3.

[0023] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5This utility model provides an anti-detachment rubber sealing ring. The positioning structure 4 includes a fixing ring 41, which is installed inside the sealing ring 3. The fixing ring 41 also plays the role of positioning and maintaining shape, and also provides support to ensure the stability of the mounting shaft in the sealing ring 3. An extension plate 49 is integrally formed on the surface of the fixing ring 41, an extension portion 410 is integrally formed on the surface of the extension plate 49, and a connecting screw 42 is integrally formed on the surface of the extension plate 49.

[0024] The extension 410 is embedded in the sealing ring 3 to prevent the sealing ring 3 from separating from the extension plate 49 when the sealing ring 3 is under force.

[0025] In this utility model, the sealing ring 3 has an installation port 46, and a pressure ring 43 is installed in the installation port 46. The pressure ring 43 has a mating interface 44, which can be connected to the connecting screw 42. A nut 45 is threaded onto the connecting screw 42. The inner diameter of the pressure ring 43 is larger than the inner diameter of the sealing ring 3, so that the shaft will not contact the pressure ring 43 after it is installed in the sealing ring 3.

[0026] In this utility model, the fixing ring 41 is provided with a connecting port 47, and the surface of the pressure ring 43 is provided with a connecting rod 48. There are six connecting rods 48. The number of connecting ports 47 is the same as the number of connecting rods 48, and the number of mating interfaces 44 is the same as the number of connecting rods 48. The position of the connecting rod 48 corresponds to the mating interface 44, so that after the mating interface 44 is aligned with the connecting screw 42, the connecting rod 48 can be mated with the connecting port 47, thus realizing the convenience of installation.

[0027] Specifically, the sealing ring 3 is inserted into the mounting port 2, then the connecting screw 42 passes through the housing 1, and then the extension plate 49 is placed against the surface of the housing 1. Then, the pressure ring 43 is placed into the mounting port 46. At this time, the interface 44 is aligned with the connecting screw 42, and then the nut 45 is threadedly connected to the connecting screw 42. Tightening the nut 45 causes the pressure ring 43 to be pushed and locked onto the surface of the housing 1. Under the action of the extension plate 49 and the pressure ring 43, the sealing ring 3 is locked in the mounting port 2. With the extension plate 49 and the pressure ring 43 clamped in the housing 1, the sealing ring 3 can be effectively prevented from being dislodged from the mounting port 2 due to force, thus improving the anti-dislodgement effect. When the connecting rod 48 is connected to the connection port 47, the pressure ring 43 and the sealing ring 3 can be prevented from being misaligned.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
