[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Please refer to Figures 1-4 , an embodiment provided by the present invention: A piston guide ring includes: a first ring body 1, a connecting ring body 3 is arranged on one side of the first ring body 1, a second ring body 2 is arranged on one side of the connecting ring body 3, a first reinforcing ring seat 5 is integrally formed on the outer wall of the other side of the first ring body 1, a second reinforcing ring seat 6 is integrally formed on the outer wall of the other side of the second ring body 2, a central reinforcing ring seat 15 is arranged on one side of both the first reinforcing ring seat 5 and the second reinforcing ring seat 6, a side-end reinforcing ring seat 16 is arranged on one side of the central reinforcing ring seat 15, a first connecting seat 9 and a second connecting seat 10, and the first connecting seat 9 and the second connecting seat 10 are fixed by hot melting. Embedding grooves 8 are arranged on the inner walls of both the first connecting seat 9 and the second connecting seat 10, a reinforcing ring 7 is embedded inside the embedding grooves 8, a guide groove 4 is arranged at the center of the first ring body 1, and the guide groove 4 penetrates through the first ring body 1, the connecting ring body 3 and the second ring body 2.

[0023] When installing the piston guide ring composed of the first ring body 1, the second ring body 2 and the connecting ring body 3, by inserting the first reinforcing ring seat 5, the second reinforcing ring seat 6, the central reinforcing ring seat 15 and the side-end reinforcing ring seat 16 into the preset ring seat grooves respectively, and the first ring body 1 and the second ring body 2 each have three reinforcing ring seats, a three-stage fixation is achieved, that is, a three-stage stable reinforcement is achieved, avoiding the piston guide ring from moving up and down or slipping when the piston rod moves in the guide groove 4, improving the connection stability. When the piston rod moves along the guide groove 4, a three-stage guiding operation is performed on the piston rod by the first ring body 1, the reinforcing ring 7 and the second ring body 2, improving the guiding distance and guiding stability.

[0024] Please refer to Figure 2 、 3 、4. There is a first stable slot 11 on the inner wall of the embedding groove 8 of the first connecting seat 9, and a second stable slot 12 on the inner wall of the embedding groove 8 of the second connecting seat 10. There is a first stable plug 13 on the outer wall of the reinforcing ring 7, and a second stable plug 14 is arranged on one side of the first stable plug 13. The first stable plug 13 and the second stable plug 14 are respectively inserted into the first stable slot 11 and the second stable slot 12. The first stable plug 13 and the second stable plug 14 are made of rubber material. The reinforcing ring 7 is embedded into the embedding groove 8, and the first stable plug 13 and the second stable plug 14 are respectively inserted into the first stable slot 11 and the second stable slot 12. Since the first stable plug 13 and the second stable plug 14 are made of rubber material, they have toughness, which is convenient for the first stable plug 13 and the second stable plug 14 to be inserted. The first stable plug 13 and the second stable plug 14 are relied on to play a limiting effect, avoiding the rotation and offset of the reinforcing ring 7 and improving the stability.

[0025] Furthermore, the first ring body 1, the connecting ring body 3 and the second ring body 2 are all made of polyoxymethylene material, and the reinforcing ring 7 is also made of polyoxymethylene material. Polyoxymethylene material has good mechanical properties, wear resistance and oil resistance. When used for the piston guide ring, it can prevent the piston from directly contacting and rubbing against the cylinder block, thereby protecting the cylinder block and the piston from damage. The use of polyoxymethylene not only provides good support and guiding functions, but also ensures the linearity of the piston movement, improves the sealing effect, avoids the direct contact between the piston and the cylinder block, and prevents the cylinder wall from being scratched.

[0026] Working principle: When in use, the reinforcing ring 7 is inserted into the insertion groove 8, and the first stable insertion post 13 and the second stable insertion post 14 are respectively inserted into the first stable insertion slot 11 and the second stable insertion slot 12. Since the first stable insertion post 13 and the second stable insertion post 14 are made of rubber material, they are ductile, facilitating the insertion of the first stable insertion post 13 and the second stable insertion post 14. By relying on the first stable insertion post 13 and the second stable insertion post 14, a limiting effect is achieved, preventing the reinforcing ring 7 from rotating and shifting, improving stability. When installing the piston guide ring composed of the first ring body 1, the second ring body 2, and the connecting ring body 3, the first reinforcing ring seat 5, the second reinforcing ring seat 6, the central reinforcing ring seat 15, and the side-end reinforcing ring seat 16 are respectively inserted into the pre-set ring seat grooves. The first ring body 1 and the second ring body 2 each have three reinforcing ring seats, achieving a three-stage fixation, that is, achieving a three-stage stable reinforcement, preventing the piston rod from driving the piston guide ring to move up and down or even slip when moving in the guide groove 4, improving the connection stability. When the piston rod moves along the guide groove 4, a three-stage guiding operation is performed on the piston rod by relying on the first ring body 1, the reinforcing ring 7, and the second ring body 2, improving the guiding distance and guiding stability.
