Description

Technical Field

[0001] This utility model relates to the field of hydraulic components technology, specifically to a method of adding a dirt-collecting groove by reversing the dirt-collecting ring. Background Technology

[0002] The guide sleeve (also known as the guide ring or support ring) of a hydraulic cylinder is a critical and often essential component. Installed inside the cylinder head (cylinder cover) between the cylinder barrel and the piston rod, the guide sleeve primarily bears and withstands the lateral forces generated when the piston rod extends (such as radial forces caused by load imbalance or installation errors), prevents direct contact between the piston rod and the cylinder barrel, maintains the coaxiality of the piston rod during movement, avoids rod bending or uneven wear, and extends the life of the seals. It also acts as a seal, isolating contaminants. Current guide sleeves typically have a built-in single buffer ring, and their internal components are mostly for sealing and support. However, over time, external dust can still penetrate into the cylinder, affecting its performance. Utility Model Content

[0003] The purpose of this invention is to provide a method for adding a sludge-collecting tank by reversing the sludge-collecting ring, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: It includes a guide sleeve, with two support ring grooves at one end of the inner side of the guide sleeve, a buffer ring groove between the two support ring grooves on the inner side of the guide sleeve, a main sealing groove at the middle of the inner side of the guide sleeve, and a reverse buffer ring groove, a dirt storage groove, and a dustproof ring groove at the other end of the inner side of the guide sleeve. A dustproof ring is connected and disposed within the dustproof ring groove, and a reinforcing ring and a buffer ring are connected and disposed within the reverse buffer ring groove.

[0005] Preferably, the guide sleeve has a fitting groove on its surface and a retaining groove and a limiting groove on one side. A cylinder is provided on the surface of the guide sleeve. A sealing cover is provided between the retaining groove and the cylinder. A limiting ring is provided on one side of the limiting groove. One end of the sealing cover is lowered to the limiting ring. An auxiliary sealing ring is provided inside the fitting groove.

[0006] Preferably, a main sealing ring is connected and disposed in the main sealing groove, a support ring is connected and disposed in the support ring groove, a connecting ring is connected and disposed in the buffer ring groove, and a reinforcing ring is connected and disposed on one side of the connecting ring.

[0007] Preferably, a piston rod is provided inside the guide sleeve, and the dustproof ring, buffer ring, support ring, connecting ring and reinforcing ring are all in contact with the surface of the piston rod.

[0008] Preferably, the reverse buffer ring groove is located between the sludge storage tank and the dustproof ring groove.

[0009] In summary, this application includes the following beneficial technical effects:

[0010] The dustproof ring serves as the first line of defense against dust, and together with the internal buffer ring, it provides a second layer of dust protection. At the same time, the newly added sludge storage tank can store excess dirt, preventing it from entering the cylinder and ensuring the cleanliness of the internal hydraulic oil. This further isolates contaminants and guarantees lubrication and support performance. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 The present invention provides a technical solution: including a guide sleeve 1, with two support ring grooves 2 opened at one end of the inner side of the guide sleeve 1, a buffer ring groove 3 opened between the two support ring grooves 2 on the inner side of the guide sleeve 1, a main sealing groove 4 opened in the middle of the inner side of the guide sleeve 1, and a reverse buffer ring groove 5, a dirt storage groove 6 and a dustproof ring groove 7 opened at the other end of the inner side of the guide sleeve 1, the reverse buffer ring groove 5 being located between the dirt storage groove 6 and the dustproof ring groove 7, a dustproof ring 9 being connected in the dustproof ring groove 7, and a reinforcing ring 10 and a buffer ring 11 being connected in the reverse buffer ring groove 5;

[0018] Reference Figure 1 As shown, the guide sleeve 1 has a fitting groove 15 on its surface, and an auxiliary sealing ring is connected and installed in the fitting groove 15. A retaining groove 16 and a limiting groove 17 are provided on one side. A sealing cover 18 is provided between the retaining groove 16 and the cylinder body 111, thereby connecting and sealing the guide sleeve 1 and the cylinder body 111. The cylinder body 111 is provided on the surface of the guide sleeve 1. A limiting ring is connected and installed on one side of the limiting groove 17. One end of the sealing cover 18 is lowered to the limiting ring, thereby limiting and fixing the sealing cover 18.

[0019] Reference Figure 3 As shown, a main sealing ring 8 is connected and installed in the main sealing groove 4, a support ring 12 is connected and installed in the support ring groove 2, a connecting ring 13 is connected and installed in the buffer ring groove 3, and a reinforcing ring 14 is connected and installed on one side of the connecting ring 13. This is a common configuration in the prior art, which can ensure the sealing effect between the piston rod 222 and the guide sleeve 1, thereby ensuring that the hydraulic oil in the cylinder 111 will not leak.

[0020] A piston rod 222 is installed inside the guide sleeve 1. The dustproof ring 9, buffer ring 11, support ring 12, connecting ring 13 and reinforcing ring 14 are all in contact with the surface of the piston rod 222. The buffer ring 11 is installed in reverse with its lip facing outward, which further cleans the surface of the piston rod 222.

[0021] The implementation principle of this application is as follows: When this utility model is in use, the dustproof ring 9 in the dustproof ring groove 7 can clean and scrape off the dust on the surface of the piston rod 222 as soon as the piston rod 222 retracts into the cylinder body 111. At the same time, the buffer ring 11, which is set in the opposite direction in the reverse buffer ring groove 5, can further clean the dust on the surface of the piston rod 222. The newly added dirt storage groove 6 can collect the dust remaining on the surface of the piston rod 222 after it has been scraped off by the buffer ring 11 when the hydraulic cylinder is in use.
