DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application;Obviously, the described embodiments are only a part of the embodiments of the application, and not all the embodiments of the application;Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the application.

[0030] As Figs. 1-3 shown, the application discloses a stop ring convenient to disassemble, which comprises a main ring body 1, a sliding rod 2, a limiting assembly 3, a rubber sheet 8 and a temperature resistant epoxy adhesive layer 9. A sliding groove 11 is formed in the side wall of the main ring body 1, the sliding rod 2 is a rod-shaped structure with an arc-shaped cross section, the sliding rod 2 is fixed on the side wall of the main ring body 1, and the sliding rod 2 is slidably connected with the sliding groove 11.

[0031] A first threaded groove 21 communicating with the sliding groove 11 is provided on the side wall of the main ring body 1. A limiting component 3 is provided on the main ring body 1 to limit the sliding rod 2. The limiting component 3 includes a fixing screw 31 and a protective block 32. The fixing screw 31 is threaded into the first threaded groove 21. The protective block 32 is a circular block structure and is fixed to the bottom surface of the fixing screw 31.

[0032] When the worker puts the main ring 1 on the bearing, the worker only needs to connect the fixing screw 31 with the first threaded groove 21, so that the protective block 32 can move downward with the fixing screw 31 and press against the upper surface of the sliding rod 2, thereby keeping the sliding rod 2 stable under the action of the protective block 32.

[0033] The main ring 1 has a second threaded groove 4 that communicates with the sliding groove 11 on its side wall. The second threaded groove 4 is matched with the fixing screw 31. The upper surface of the sliding rod 2 has a second mounting groove 41. The inner wall of the second mounting groove 41, which is away from the first threaded groove 21, intersects with the upper surface of the sliding rod 2 and has a first inclined surface 5.

[0034] When the worker needs to disassemble the main ring 1, the worker needs to separate the fixing screw 31 from the first threaded groove 21 and connect the fixing screw 31 to the second threaded groove 4. This will allow the protective block 32 to move downward with the fixing screw 31 and press against the first inclined surface 5. As a result, the sliding rod 2 moves away from the first threaded groove 21 under the action of the protective block 32, thereby gradually increasing the opening of the main ring 1 and reducing the difficulty for the worker to remove the main ring 1.

[0035] To improve the user experience, a first mounting groove 51 is provided on the upper surface of the sliding rod 2, and a second inclined surface 6 is provided on the edge where the inner wall of the first mounting groove 51, away from the second threaded groove 4, intersects with the upper surface of the sliding rod 2.

[0036] When the operator connects the fixing screw 31 to the first threaded groove 21, the operator only needs to rotate the fixing screw 31 to make the protective block 32 gradually move downward and press against the second inclined surface 6, thereby improving the tightness of the connection between the sliding rod 2 and the inner wall of the sliding groove 11, and thus improving the operator's user experience.

[0037] In order to reduce the probability of damage to the first inclined surface 5 and the second inclined surface 6, thereby extending the service life of the sliding rod 2, the protective block 32 is made of silicone.

[0038] A snap-fit ​​groove 7 is provided on the inner wall of the main ring body 1, and the rubber sheet 8 has a sheet-like structure, which is snap-fitted and fixed in the snap-fit ​​groove 7. This design improves the tightness of the connection between the main ring body 1 and the bearing, thereby improving the user experience of the main ring body 1.

[0039] The temperature-resistant epoxy adhesive layer 9 is arranged on the inner wall of the clamping groove 7, and the temperature-resistant epoxy adhesive layer 9 is fixed with the rubber sheet 8. The temperature-resistant epoxy adhesive layer 9 made of temperature-resistant epoxy adhesive can withstand high temperature, generally above 200 degrees Celsius, and even resist higher temperature in some special formula. It is suitable for the combination between metal, plastic and ceramic, especially widely used in the automobile manufacturing and aerospace industry, thereby effectively reducing the probability of mutual separation of the rubber sheet 8 and the clamping groove 7.

[0040] In order to prolong the service life of the sliding rod 2, the sliding rod 2 is made of stainless steel.

[0041] The working principle of the detachable retainer ring in the embodiment is as follows: when the working personnel need to install the retainer ring, the working personnel need to connect the main ring body 1 with the bearing. At this time, the working personnel need to connect the fixing screw 31 with the second threaded groove 4, so that the opening of the main ring body 1 is enlarged under the joint action of the fixing screw 31 and the first inclined surface 5, thereby reducing the difficulty of the working personnel in sleeving the main ring body 1 on the bearing. Then, the working personnel only need to disassemble the fixing screw 31 and connect the fixing screw 31 with the first threaded groove 21, so that the sliding rod 2 is kept stable under the action of the limiting assembly 3, thereby keeping the main ring body 1 stable, and further reducing the difficulty of the working personnel in installing the main ring body 1.

[0042] The above is only the preferred embodiment of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solution belonging to the idea of the present application is within the protection scope of the present application. It should be noted that, for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principle of the present application are also considered as the protection scope of the present application.
