[0024] Please see Figure 1 - Figure 7An oil cooler for a compressor includes an oil cooler body 1. A limiting groove 9 is formed on the inner wall of the oil cooler body 1. A limiting rod 10 is slidably connected to the inner wall of the limiting groove 9. A sealing ring 4 is fixedly mounted on the outer wall of the limiting rod 10. A fixing block 5 is fixedly mounted on the outer wall of the sealing ring 4. A threaded groove 7 is formed on the outer wall of the fixing block 5. A bolt 8 is threadedly connected to the inner wall of the threaded groove 7. A nut 17 is threadedly connected to the end of the bolt 8. A movable groove 14 is formed on the inner wall of the fixing block 5. One end of a spring 15 is fixedly mounted on the inner wall of the movable groove 14. A clamping block 16 is fixedly mounted on the other end of the spring 15. A placement block 12 is fixedly mounted on the outer wall of the oil cooler body 1. A limiting component 6 is provided at the bottom of the placement block 12.

[0025] In the above structure, during the installation of the connecting pipe 2 and the oil cooler body 1, the operator first places the sealing ring 4 into the inner wall of the oil cooler body 1, then moves the limiting rod 10 within the inner wall of the limiting groove 9. Next, the connecting pipe 2 is placed within the inner wall of the sealing ring 4. The operator pulls the clamping block 16 to move the spring 15 within the inner wall of the moving groove 14. When the connecting pipe 2 is placed within the inner wall of the sealing ring 4 again, the limiting of the clamping block 16 is released, releasing the elastic potential energy of the spring 15. The spring 15 then drives the clamping block 16 to clamp and fix the oil cooler body 1 and the connecting pipe 2. In addition, the operator rotates the bolt 8 to the inner wall of the threaded groove 7 and rotates the nut 17 to the end of the bolt 8 to achieve the connection between the oil cooler body 1 and the connecting pipe 2 and ensure better sealing.

[0026] In a preferred embodiment: the bottom of the oil cooler body 1 is provided with a mounting base 3, the top of the mounting base 3 is fixedly fitted with a toothed block 11, the outer wall of the placement block 12 is provided with a sliding groove 13, and the outer wall of the oil cooler body 1 is provided with a connecting pipe 2.

[0027] In the above structure, the oil cooler body 1 is fixed by the mounting base 3 so that the oil cooler body 1 will not rotate during operation. The limiting component 6 is limited by the sliding groove 13. The two ends of the oil cooler body 1 are closed by the connecting pipe 2 to prevent leakage during operation.

[0028] In a preferred embodiment: the limiting component 6 includes a rotating rod 601, and a rotating disk 602 and a gear 603 are fixedly mounted on the outer wall of the rotating rod 601 respectively. The outer wall of the gear 603 is provided with a rack 604, and a sliding block 605 is fixedly mounted on the outer wall of the rack 604. A second rack 606 is fixedly mounted on the outer wall of the sliding block 605.

[0029] In the above structure, during the installation of the oil cooler body 1, the operator places the mounting base 3 on the outer wall of the placement block 12. Then, the operator rotates the rotating disk 602, which applies pressure to the rotating disk 602, thereby causing the rotating rod 601 to rotate on the inner wall of the placement block 12. During the rotation of the rotating rod 601, the gear 603 will rotate accordingly. The meshing transmission mechanism between the gear 603 and the rack 604 ensures that the gear 603 can drive the rack 604 and the sliding block 605 to move on the inner wall of the sliding groove 13 when rotating. During the movement of the rack 604, the rack 604 will drive the rack 606 to clamp the top toothed block 11 of the mounting base 3, thereby limiting the placement block 12 and the mounting base 3. This series of actions ensures that the stability of the entire device is enhanced during the installation of the oil cooler body 1.

[0030] In a preferred embodiment: the rotating rod 601 is rotatably connected to the inner wall of the placement block 12, the gear 603 meshes with the rack 604, the sliding block 605 is slidably connected to the inner wall of the sliding groove 13, and the rack 606 meshes with the toothed block 11.

[0031] In the above structure, the limiting component 6 is limited by the placement block 12, making the limiting component 6 more stable during operation or placement. When the gear 603 rotates, it will drive the rack 604 to move. The sliding groove 13 limits the sliding block 605 and the rack 604, making the rack 604 more stable during movement. When the rack 606 is placed on the outer wall of the toothed block 11, it will limit the mounting base 3.

[0032] In a preferred embodiment: the limiting rod 10 is fixedly assembled with the inner wall of the sealing ring 4, and the threaded groove 7 is formed on the outer wall of the connecting pipe 2.

[0033] In the above structure, the sealing ring 4 is limited by the limiting rod 10, making the sealing ring 4 more stable when placed. The oil cooler body 1 and the connecting pipe 2 are connected and fixed by the threaded groove 7, bolt 8 and nut 17.

[0034] In a preferred embodiment, there are two sets of limiting components 6, and the two sets of limiting components 6 are located at the bottom of the oil cooler body 1.

[0035] In the above structure, two sets of limiting components 6 are used to limit the two sides of the oil cooler body 1 to prevent one end of the oil cooler body 1 from tilting during installation.

[0036] Working principle: During the connection of the connecting pipe 2 to the oil cooler body 1, the operator first places the sealing ring 4 into the inner wall of the oil cooler body 1, then moves the limiting rod 10 within the inner wall of the limiting groove 9. Subsequently, the connecting pipe 2 is placed into the inner wall of the sealing ring 4, and the clamping block 16 is pulled, causing the clamping block 16 to drive the spring 15 to move within the inner wall of the moving groove 14. When the connecting pipe 2 is placed into the inner wall of the sealing ring 4, the limiting of the clamping block 16 is released, releasing the elastic potential energy of the spring 15. The spring 15 then drives the clamping block 16 to clamp and fix the oil cooler body 1 and the connecting pipe 2. At the same time, the operator rotates the bolt 8 to the inner wall of the threaded groove 7 and rotates the nut 17 to the end of the bolt 8 to achieve oil... The cooler body 1 and the connecting pipe 2 are connected and the sealing is enhanced. When installing the oil cooler body 1, the operator places the mounting base 3 on the outer wall of the placement block 12 and rotates the rotating disk 602. The pressure of the rotating disk 602 drives the rotating rod 601 to rotate on the inner wall of the placement block 12, which in turn drives the gear 603 to rotate. The gear 603 meshes with the rack 604, so that when the gear 603 rotates, it drives the rack 604 and the sliding block 605 to move on the inner wall of the sliding groove 13. When the rack 604 moves, it drives the rack 606 to clamp the toothed block 11 on the top of the mounting base 3, thereby limiting the placement block 12 and the mounting base 3 and ensuring the stability of the process when installing the oil cooler body 1.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
