[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figure 1 shown;

[0027] A sealing structure of a compressor cooler includes a shell-side outer shell 1.

[0028] In this implementation: Although this design can eliminate the uneven force on the sealing contact surface by changing the fastening force point, improving the sealing effect and extending the service life of the sealing ring 211, however, this device is fixed by bolts, and in case of leakage or other emergencies, the disassembly of this device is rather cumbersome and cannot cope with emergencies. At the same time, when maintaining and operating this device, the staff needs to spend a lot of energy on disassembly, reducing the work efficiency. To solve this technical problem, a sealing component 2 is added on this basis.

[0029] Furthermore:

[0030] As Figures 1 to 5 shown:

[0031] Combined with the above content: The sealing component 2 includes a sliding sleeve 21, a spring 22 and a limiting ball 23. The outer side of the end of the shell-side outer shell 1 is slidably connected with the sliding sleeve 21. The outer sides of both ends of the spring 22 are fixedly connected with the inner side of the end of the sliding sleeve 21 and the outer side of one end of the shell-side outer shell 1 respectively. The limiting ball 23 is movably connected inside the through hole annularly opened at the end of the shell-side outer shell 1. The inner side of the end of the shell-side outer shell 1 is slidably connected with a sealing head 24. A pressure rod 25 is threadedly connected at the central position of the sealing head 24. A pressure head 26 is fixedly connected to the outer side of the end of the pressure rod 25. A retaining ring 210 is fixedly connected to the inner side of the end of the shell-side outer shell 1. A rubber ring 27 is fixedly connected to the outer side of the end of the retaining ring 210. The material of the rubber ring 27 is rubber. A plurality of anti-slip strips 29 are annularly fixedly connected to the outer side of the end of the pressure rod 25. The material of the anti-slip strips 29 is rubber. The lower surface of the pressure head 26 is in contact with the outer side of the end of the rubber ring 27. The limiting ball 23 is in contact with the inside of the annular groove opened at the inner side of the end of the sealing head 24.

[0032] In this embodiment: In this device, the sliding sleeve 21 is a hollow annular structure. The sliding sleeve 21 is slidably connected to the outer side of the end of the shell-side housing 1, and at the same time, the sliding sleeve 21 is connected to the shell-side housing 1 through a spring 22. When the user needs to use the device for sealing, the user can first slide the sliding sleeve 21 downward, while compressing the spring 22 to store the elastic potential energy of the spring 22. At this time, the sliding sleeve 21 loses the limitation on the position of the limit ball 23. At this time, the user can dial the sealing head 24 outward to disassemble the sealing head 24. When the user needs to seal the device, the user only needs to slide the sliding sleeve 21 again and insert the sealing head 24 at the same time. During the insertion process of the sealing head 24, the limit ball 23 on the inner side of the end of the shell-side housing 1 is snapped into the annular groove inside the sealing head 24. At this time, the spring 22 releases the elastic potential energy. Under the action of the spring 22, the spring 22 moves toward the sealing head 24. At the same time, the outer side of the end of the sliding sleeve 21 abuts against one side of the limit ball 23 to limit the position of the limit ball 23, that is, one side of the limit ball 23 is fixed inside the annular groove of the sealing head 24, that is, the sealing operation of the device is completed. The device can be quickly fixed and disassembled through the sliding sleeve 21 and the limit ball 23. The convenient disassembly design enables quick operation when the sealing structure of the cooler needs to be maintained or replaced, thereby reducing the equipment downtime and improving the work efficiency. The sealing structure is an important part of the compressor cooler. Good sealing performance can ensure the stable pressure inside the cooler. By quickly replacing the worn or damaged rubber ring 27 and sealing ring 211, long-term sealing effect can be ensured. The convenient disassembly design enables quick maintenance and replacement in case of leakage or other emergencies, reducing the accident risk.

[0033] Furthermore:

[0034] In an alternative embodiment, a plurality of anti-slip rings 28 are fixedly connected to the outer side of the end of the sliding sleeve 21, and the anti-slip rings 28 are made of silica gel.

[0035] In this embodiment: An anti-slip ring 28 is fixedly connected to the outer surface of the sliding sleeve 21. The main function of the anti-slip ring 28 is to increase the friction between the sliding sleeve 21 and the hand, prevent the sliding sleeve 21 from accidentally sliding or shifting during use. The anti-slip ring 28 can greatly reduce the safety risk caused by sliding. After the sliding sleeve 21 is installed with the anti-slip ring 28, its wear degree will be greatly reduced. The anti-slip ring 28 can bear part of the friction force, reduce the burden on the sliding sleeve, thereby reducing wear and extending its service life.

[0036] Furthermore:

[0037] In an alternative embodiment, a plurality of anti-slip strips 29 are annularly and fixedly connected to the outer side of the end of the pressure rod 25, and the anti-slip strips 29 are made of rubber.

[0038] In this embodiment: A plurality of anti-slip strips 29 are fixedly connected to the outer side of the end of the pressure rod 25. The anti-slip strips 29 can significantly enhance the friction between the pressure rod 25 and the hand, effectively preventing the sliding phenomenon during rotation. By rotating the pressure rod 25, the user can freely adjust the pressure of the pressure head 26 on the rubber ring 27, and thus can correspondingly adjust the sealing degree of the device.

[0039] Working principle: In this device, the sliding sleeve 21 is an annular structure with a hollow interior. The sliding sleeve 21 is slidably connected to the outer side of the end of the shell-side housing 1, and at the same time, the sliding sleeve 21 is connected to the shell-side housing 1 through a spring 22. When the user needs to use the device for sealing, the user can first slide the sliding sleeve 21 downward and compress the spring 22 to store the elastic potential energy of the spring 22. At this time, the sliding sleeve 21 loses the limitation on the position of the limit ball 23. At this time, the user can dial the sealing head 24 outward to disassemble the sealing head 24. When the user needs to seal the device, the user only needs to slide the sliding sleeve 21 again and insert the sealing head 24. During the insertion of the sealing head 24, the limit ball 23 on the inner side of the end of the shell-side housing 1 is caught in the annular groove inside the sealing head 24. At this time, the spring 22 releases the elastic potential energy. Under the action of the spring 22, the spring 22 moves towards the sealing head 24. At the same time, the outer side of the end of the sliding sleeve 21 abuts against one side of the limit ball 23 to limit the position of the limit ball 23, that is, one side of the limit ball 23 is fixed in the annular groove inside the sealing head 24, thus completing the sealing operation of the device. Through the sliding sleeve 21 and the limit ball 23, the device can be quickly fixed and disassembled. The convenient disassembly design enables quick operation when the sealing structure of the cooler needs maintenance or replacement, thereby reducing the equipment downtime and improving the work efficiency. The sealing structure is an important part of the compressor cooler. Good sealing performance can ensure the internal pressure stability of the cooler. By quickly replacing the worn or damaged rubber ring 27 and sealing ring 211, long-term sealing effect can be ensured. The convenient disassembly design enables quick repair and replacement in case of leakage or other emergencies, reducing the accident risk. An anti-slip ring 28 is fixedly connected to the outer surface of the sliding sleeve 21. The main function of the anti-slip ring 28 is to increase the friction between the sliding sleeve 21 and the hand, preventing the sliding sleeve 21 from accidentally sliding or shifting during use. The anti-slip ring 28 can greatly reduce the safety risk caused by sliding. After the sliding sleeve 21 is installed with the anti-slip ring 28, its wear degree will be greatly reduced. The anti-slip ring 28 can bear part of the friction, reducing the burden on the sliding sleeve, thereby reducing wear and extending its service life. A plurality of anti-slip strips 29 are fixedly connected to the outer side of the end of the pressure rod 25. The anti-slip strips 29 can significantly enhance the friction between the pressure rod 25 and the hand, effectively preventing the sliding phenomenon during rotation. By rotating the pressure rod 25, the user can freely adjust the pressure of the pressure head 26 on the rubber ring 27, and thus can correspondingly adjust the sealing degree of the device.
