Description

Technical Field

[0001] The utility model relates to the technical field of guide sleeves, in particular to a novel split guide sleeve. Background Art

[0002] In hydraulic cylinders, the most commonly used guide element is the guide sleeve. The guide sleeve can bear the radial load acting on the hydraulic cylinder assembly and provide a guiding function for the piston rod in the cylinder head and the piston in the cylinder barrel. The guide element is made of polymer material to avoid metal contact between moving parts in the working hydraulic cylinder.

[0003] In the prior art, the guide sleeve is mostly an integrated structure, and No. 45 steel is often used as the manufacturing material of the guide sleeve. During the long-term use of the hydraulic cylinder, a certain amount of hydraulic oil or water may exist on the inner wall of the guide sleeve. If it is not treated, it may cause the inner wall of the entire guide sleeve to rust, thereby damaging the entire guide sleeve and shortening the service life of the guide sleeve.

[0014] Preferably, the left side of the outer wall of the retaining ring contacts the inner wall of the guide sleeve body, and the outer wall of the guide sleeve body is fixedly connected with a boss. When the outer wall of the retaining ring contacts the tail end of the mounting groove, the guide sleeve docking body is completely inserted into the mounting groove of the guide sleeve body.

[0015] The beneficial effects of the utility model are as follows:

[0016] 1. The utility model provides a guide sleeve body and a guide sleeve docking body, wherein the guide sleeve body is made of stainless steel to prevent the guide sleeve body from rusting during long-term use, and the guide sleeve docking body is made of No. 45 steel. The guide sleeve docking body is inserted into the installation groove of the guide sleeve body until the outer wall of the retaining ring contacts the tail end of the installation groove, thereby ensuring the original structural strength of the guide sleeve while extending the service life of the guide sleeve.

[0017] 2. The utility model provides a dustproof ring, and places the dustproof ring in the slide groove, which can further reduce the entry of external dust into the guide sleeve main body and the guide sleeve docking body. The dustproof ring can be fixed by providing a fixing sleeve and a limiting ring. When the elastic pressure plate on the surface of the limiting ring contacts the dustproof ring, the elastic pressure plate undergoes elastic deformation under the mutual squeezing force of the dustproof ring and the limiting ring, thereby pressing the dustproof ring, which facilitates the replacement process of the dustproof ring.

The inner wall of the guide sleeve docking body 2 is slidably connected with the outer wall of the dust ring 6 through the slide groove 22, and the slide groove 22 is opened in the inner wall of the guide sleeve docking body 2. A limiting ring 7 is arranged on the right side of the dust ring 6, and an elastic pressure plate 8 is fixedly connected to the inner wall of the limiting ring 7. The left side of the outer wall of the elastic pressure plate 8 contacts the right side of the outer wall of the dust ring 6. The right side of the inner wall of the guide sleeve docking body 2 is threadedly connected with a fixing sleeve 3 through a threaded groove 23, and the threaded groove 23 is opened in the inner wall of the right side of the guide sleeve docking body 2. By placing the dustproof ring 6 in the slide groove 22, the entry of external dust into the guide sleeve main body 1 and the guide sleeve docking body 2 can be reduced. When the fixed sleeve 3 is rotated, the fixed sleeve 3 moves along the surface of the threaded groove 23, forcing the limiting ring 7 to approach the dustproof ring 6. When the elastic pressure plate 8 fixed on the surface of the limiting ring 7 contacts the surface of the dustproof ring 6, the elastic pressure plate 8 undergoes elastic deformation under the mutual squeezing force of the dustproof ring 6 and the limiting ring 7, thereby pressing the dustproof ring 6. When the fixed sleeve 3 is rotated in the opposite direction and the fixed sleeve 3 is removed, the limiting ring 7 can be taken out from the guide sleeve docking body 2 together with the dustproof ring 6, thereby facilitating the replacement process of the dustproof ring 6.

[0031] The inner wall of the guide sleeve body 1 is movably mounted with an oil seal ring 4 through a limiting groove 11, and the limiting groove 11 is provided in the inner wall on the left side of the guide sleeve body 1, the inner wall of the guide sleeve body 1 is movably mounted with a seal ring 5 through a fixing groove 12, and the fixing groove 12 is provided in the inner wall of the guide sleeve body 1, the outer wall of the limiting ring 7 is slidably connected to the inner wall of the guide sleeve docking body 2 through a slide groove 22, a retaining ring 21 is fixedly connected to the left side of the inner wall of the guide sleeve docking body 2, the right side of the outer wall of the limiting ring 7 contacts the left side of the outer wall of the fixing sleeve 3, the left side of the outer wall of the retaining ring 21 contacts the inner wall of the guide sleeve body 1, the outer wall of the guide sleeve body 1 is fixedly connected with a boss 13, and is installed on the limiting groove 12. The oil seal ring 4 in the positioning groove 11 can prevent the oil attached to the surface of the output end of the hydraulic cylinder from entering the guide sleeve body 1.

The guide sleeve body 1 is made of stainless steel to prevent the guide sleeve body 1 from rusting during long-term use. The guide sleeve docking body 2 is made of No. 45 steel. The guide sleeve docking body 2 is inserted into the installation groove 14 of the guide sleeve body 1 until the outer wall of the retaining ring 21 contacts the tail end of the installation groove 14, thereby ensuring the original structural strength of the guide sleeve, thereby extending the service life of the guide sleeve.

[0032] Working principle:

[0033] When in use, the oil seal ring 4 installed in the limiting groove 11 can prevent the oil attached to the surface of the output end of the hydraulic cylinder from entering the guide sleeve body 1, and the sealing ring 5 installed in the fixing groove 12 can prevent dust or impurities from entering the guide sleeve body 1, thereby extending the service life of the oil seal ring 4. The guide sleeve body 1 is made of stainless steel to prevent the guide sleeve body 1 from rusting during long-term use. The guide sleeve docking body 2 is made of No. 45 steel. The guide sleeve docking body 2 is inserted into the installation groove 14 of the guide sleeve body 1 until the outer wall of the retaining ring 21 contacts the tail end of the installation groove 14, thereby ensuring the original structural strength of the guide sleeve, thereby extending the service life of the guide sleeve;

[0034] By placing a dustproof ring 6 in the slide groove 22, the entry of external dust into the guide sleeve main body 1 and the guide sleeve docking body 2 can be further reduced. When the fixing sleeve 3 is rotated, the fixing sleeve 3 moves along the surface of the threaded groove 23, forcing the limiting ring 7 to approach the dustproof ring 6. When the elastic pressure plate 8 fixed on the surface of the limiting ring 7 contacts the surface of the dustproof ring 6, the elastic pressure plate 8 undergoes elastic deformation under the mutual squeezing force of the dustproof ring 6 and the limiting ring 7, thereby pressing the dustproof ring 6. When the fixing sleeve 3 is rotated in the opposite direction and the fixing sleeve 3 is removed, the limiting ring 7 can be taken out from the guide sleeve docking body 2 together with the dustproof ring 6, thereby facilitating the replacement process of the dustproof ring 6.
