A first fixing block 2 and a second fixing block 3 are respectively arranged in the first installation groove and the second installation groove. A slot 4 is opened on the first fixing block 2, and a plug 5 is arranged on the second fixing block 3. The size and position of the plug 5 correspond to those of the slot 4. A guiding groove 6 is opened on the inner wall of the slot 4, a limiting block 7 is arranged in the guiding groove 6, a telescopic rod 8 is arranged on the outer wall of the limiting block 7, the other end of the telescopic rod 8 is fixedly connected to the inner wall of the guiding groove 6, a limiting hole 9 is arranged on the plug 5, and the position of the limiting block 7 corresponds to that of the limiting hole 9.

[0031] An elastic rubber sealing ring with a V-shaped cross-section and axial action of the present utility model. A spring 10 is nested on the telescopic rod 8, and the spring 10 is pressed between the inner wall of the guiding groove 6 and the outer wall of the limiting block 7. Through the elastic acting force of the spring 10, a certain thrust can always be provided for the limiting block 7, so that it can always be in a clamped state with the limiting hole 9, avoiding the separation of the two and affecting the use effect.

[0032] An elastic rubber sealing ring with a V-shaped cross-section and axial action of the present utility model. Both the insertion block 5 and the limiting block 7 are provided with inclined surfaces. The inclined surface on the insertion block 5 is inclined upward, and the inclined surface on the limiting block 7 is inclined downward, which can facilitate the direct insertion of the insertion block 5 into the insertion slot 4 and improve the operation convenience.

[0033] Embodiment 2

[0034] On the basis of Embodiment 1, as Figures 1-5 shown, an elastic rubber sealing ring with a V-shaped cross-section and axial action of the present utility model. One end of the sealing ring 1 is provided with an elastic sealing block 11, and a through hole 12 is opened on the elastic sealing block 11. The position of the through hole 12 corresponds to that of the insertion slot 4, which can improve the sealing performance between the contact surfaces of the sealing ring 1.

[0035] An elastic rubber sealing ring with a V-shaped cross-section and axial action of the present utility model. A V-shaped groove 13 is opened on the sealing ring 1, and a plurality of V-shaped spring pieces 14 are evenly arranged on the V-shaped groove 13, which can play a role in sealing tension and improve the overall sealing effect.

[0036] An elastic rubber sealing ring with a V-shaped cross-section and axial action of the present utility model. The guiding groove 6 is of a rectangular structure, and the structure of the limiting block 7 matches that of the guiding groove 6, which can prevent the limiting block 7 from rotating randomly in the guiding groove 6 and affecting the use.

[0037] Embodiment 3

[0038] On the basis of Embodiment 2, as Figures 1-3 shown, an elastic rubber sealing ring with a V-shaped cross-section and axial action of the present utility model. A wear-resistant layer is coated on the sealing ring 1, which can improve the wear-resistant performance and extend the service life of the sealing ring 1.

[0039] An elastic rubber sealing ring with a V-shaped cross-section and axial action of the present utility model. The wear-resistant layer is a polyethylene layer, which has good wear-resistant performance.

[0040] An elastic rubber sealing ring with a V-shaped cross-section and axial action of the present utility model. Two insertion slots 4 are provided on the first fixing block 2, and the two insertion slots 4 are symmetrically arranged on the first fixing block 2. Similarly, two insertion blocks 5 are symmetrically arranged on the second fixing block 3, which can improve the connection tightness at both ends of the sealing ring 1.

[0041] During use, since the sealing ring 1 itself has elasticity, the opening of the sealing ring 1 can be opened, and then it can be nested at the designated position. Then, the insertion block 5 is inserted into the insertion slot 4. When the insertion block 5 is inserted into the insertion slot 4, it will contact the limit block 7. Since both of them are provided with inclined surfaces, as the insertion block 5 continues to be inserted, the limit block 7 will be squeezed into the inside of the guide groove 6. At this time, both the spring 10 and the telescopic rod 8 are in a compressed state. After the insertion block 5 is inserted in place, the limit hole 9 on the insertion block 5 will move to the position of the limit block 7. At this time, the limit block 7 loses the external thrust, so it will enter the inside of the limit hole 9 under the driving of the elasticity of the spring 10 to limit and fix the insertion block 5. Thus, the sleeving of the sealing ring 1 is completed. By this method, when the sealing ring 1 is installed, there is no need to dismantle relevant equipment, the overall operation is convenient, the practicability is strong, and the wear-resistant layer coated on the surface of the sealing ring 1 can improve the overall wear-resistant performance of the sealing ring 1 and extend the service life. When the sealing ring 1 is damaged and needs to be replaced, the sealing ring 1 can be directly cut off.

[0042] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
