[0018] The technical solutions in the embodiments of the application will be apparently and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0019] Please refer to Figures 1-4 The application provides the following technical scheme: a hydraulic oil cylinder sealing ring with an installation anti-displacement structure, comprising a sealing ring 1, an outer skirt 2 integrally connected to the surface near the outer edge on both sides of the sealing ring 1, an inner skirt 3 integrally connected to the surface near the inner edge on both sides of the sealing ring 1, and a reinforcing ring 4 installed between the inner skirt 3 and the reinforcing ring 4.

[0020] Six positioning blocks 5 are fixedly connected to the outer wall of the reinforcing ring 4 at equal intervals, each positioning block 5 is clamped in a bayonet 6, the bayonet 6 is formed in the inner wall of the outer skirt 2, and the reinforcing ring 4 is made of hard deformable rubber material.

[0021] Preferably, the outer wall of the reinforcing ring 4 is in close contact with the inner wall of the outer skirt 2, and the inner wall of the reinforcing ring 4 is in close contact with the outer wall of the inner skirt 3.

[0022] In specific use, the reinforcing ring 4 is installed between the outer skirt 2 and the inner skirt 3, can be filled between the outer skirt 2 and the inner skirt 3, provides support for the outer skirt 2 and the inner skirt 3, and the close contact between the reinforcing ring 4 and the outer skirt 2 and the inner skirt 3 can achieve a sealing effect.

[0023] Preferably, a group of butt joints 41 are formed in the outer wall of one side of the reinforcing ring 4 at equal intervals.

[0024] Preferably, a group of convex columns 11 are arranged on the surface of the sealing ring 1 between the outer skirt 2 and the inner skirt 3 at equal intervals, a semicircular head 12 is fixedly connected to the top of the convex column 11, the diameter of the semicircular head 12 is greater than the diameter of the convex column 11, the convex column 11 and the semicircular head 12 are made of hard deformable rubber material, and each group of convex columns 11 and semicircular heads 12 is in interference butt joint with one butt joint 41.

[0025] In particular use, first, the six positioning blocks 5 evenly distributed on the outer wall of the reinforcing ring 4 are aligned with the corresponding sockets 6 on the outer skirt 2. The design of the positioning blocks 5 and the sockets 6 follows the strict tolerance matching principle. Through this precise matching, it can be ensured that the reinforcing ring 4 is in the correct position in the initial installation stage, avoiding subsequent displacement problems caused by initial installation deviation.

[0026] The positioning blocks 5 are smoothly inserted into the corresponding sockets 6. At this time, the reinforcing ring 4 is preliminarily fixed between the outer skirt 2 and the inner skirt 3, but has not yet been completely installed in place.

[0027] Then, further downward extrusion force needs to be applied to the reinforcing ring 4. During the extrusion process, it is necessary to ensure that the extrusion force is evenly distributed on the top of the reinforcing ring 4, avoiding excessive deformation of the reinforcing ring 4 due to excessive local stress. With the gradual increase of the extrusion force, the butt joint 41 at the bottom of the reinforcing ring 4 will gradually approach the surface of the sealing ring 1. The corresponding convex column 11 and semicircular head 12 on the surface of the sealing ring 1 are adapted in position and size to the butt joint 41 at the bottom of the reinforcing ring 4. When the butt joint 41 is connected with the convex column 11 and the semicircular head 12, the reinforcing ring 4 is stably installed and filled between the outer skirt 2 and the inner skirt 3.

[0028] After the above installation operation, the outer skirt 2 and the inner skirt 3 on the upper and lower sides of the sealing ring 1 are reinforced by the reinforcing ring 4 in all directions. From the perspective of mechanics, the reinforcing ring 4 provides additional support to the outer skirt 2 and the inner skirt 3 due to its own toughness. When affected by external pressure or other factors that may cause deformation, the reinforcing ring 4 can effectively disperse stress and prevent the outer skirt 2 and the inner skirt 3 from deforming towards the hollow area. This reinforcing mechanism greatly enhances the stability of the sealing ring 1 during installation, making it less likely to displace, thereby effectively preventing deformation displacement and ensuring the reliability and sealing of the entire hydraulic cylinder sealing system.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application 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 technical features. Any modification, equivalent substitution, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
