[0024] Refer to the instruction manual Figure 1-5 , the utility model provides a piston-type oil cylinder guide ring, comprising a guide ring body 1 installed on the piston-type oil cylinder;

[0025] In order to improve the convenience of workers in disassembling the inner ring 2 and the outer ring 3, Figure 1-5 As shown, the guide ring body 1 includes an inner ring 2 and an outer ring 3, the outer ring 3 is sleeved on the outside of the inner ring 2, a plurality of panels 4 are installed on the outside of the inner ring 2, an embedding hole 5 is opened on the side of the outer ring 3 close to the panel 4, and the end of the panel 4 away from the inner ring 2 extends to the inside of the embedding hole 5; a plurality of positioning posts 6 are arranged between two adjacent panels 4, the positioning posts 6 are installed on the outside of the inner ring 2, and a positioning groove 7 is opened on the side of the outer ring 3 close to the positioning posts 6; the inner ring 2 and the panels 4 are both made of rubber material.

[0026] It is worth mentioning that by using highly elastic rubber material to make the insert 4 and the inner ring 2, the inner ring 2 can be stretched open to drive the positioning column 6 to be embedded in the positioning groove 7 to avoid loosening. Because the inner ring 2 can be restored to drive the positioning column 6 to separate from the positioning groove 7, the staff can directly pull out the inner ring 2, thereby improving the convenience of the staff in repairing the inner ring 2 and the outer ring 3.

[0027] In order to enhance the connection stability between the inner ring 2 and the outer ring 3 and avoid rotation, Figure 2-5 As shown, fixing plates 8 are installed on both sides of one end of the inlay plate 4 close to the inner ring 2, and a fixing hole 9 is penetrated through one side of the outer ring 3 close to the fixing plate 8, and the fixing hole 9 is connected with the inlay hole 5. Through the cooperation of the fixing plate 8 and the fixing hole 9, the inner ring 2 can be limited to avoid the inner ring 2 from rotating, thereby ensuring the stability of the inner ring 2.

[0028] In order to avoid the inner ring 2 and the outer ring 3 from loosening and separating, Figure 2 As shown, a sealing ring 10 is installed on the rear side of the outer ring 3, and the inner diameter of the sealing ring 10 is equal to the inner diameter of the outer ring 3. The panel 4 is arranged on the front side of the sealing ring 10. Through the setting of the sealing ring 10, the panel 4 can be restricted to avoid separation of the panel 4 and the outer ring 3, thereby ensuring the connection stability between the inner ring 2 and the outer ring 3.

[0029] In order to avoid wear on the protrusion of the piston cylinder, Figure 1 As shown, retaining rings 11 are provided on both the front and rear sides of the outer ring 3, and the ends of the two retaining rings 11 that are close to each other are fixed together with the front and rear sides of the outer ring 3 respectively. Through the setting of the retaining rings 11, the raised part on the piston cylinder can be covered to prevent the raised part of the piston cylinder from being worn.

[0030] In order to enhance the tightness and stability of the connection between the inner ring 2 and the outer ring 3, as Figure 2 , 4 As shown in Figure 5, the multiple panels 4 are evenly spaced and distributed. Through the arrangement of the multiple panels 4, the inner ring 2 and the outer ring 3 can be connected in multiple directions, thereby enhancing the tightness of the connection between the inner ring 2 and the outer ring 3. The multiple positioning columns 6 are evenly spaced and distributed. Through the arrangement of the multiple positioning columns 6, the connection stability between the inner ring 2 and the outer ring 3 can be enhanced, thereby achieving a layer-by-layer barrier effect and avoiding loosening and separation.

[0031] Through the cooperation of the inlay plate 4 and the inlay hole 5, the staff can insert the inner ring 2 into the outer ring 3, and the restriction of the inlay hole 5 on the inlay plate 4 can ensure the stability of the inner ring 2. After that, the staff will embed the inner ring 2 and the outer ring 3 into the outside of the piston cylinder. Because the inner ring 2 and the inlay plate 4 are made of highly elastic rubber, when the staff installs the guide ring body 1, the piston cylinder can open the inner ring 2 and make the positioning column 6 and the fixing plate 8 on the inner ring 2 be embedded in the corresponding positioning groove 7 and fixing hole 9, so as to enhance the connection stability between the inner ring 2 and the outer ring 3. When the piston cylinder is separated from the inner ring 2, the inner ring 2 shrinks and recovers, driving the positioning column 6 and the fixing plate 8 to separate from the corresponding positioning groove 7 and fixing hole 9. After that, the staff can directly pull out the inner ring 2, so as to improve the convenience of the staff to repair the inner ring 2 and the outer ring 3.
