Description

Technical Field

[0001] This utility model relates to the field of air conditioning external pipeline technology, specifically a trailer air conditioning external pipeline mechanism. Background Technology

[0002] Air conditioning connecting pipes play a crucial role in the operation of an air conditioner. An air conditioner typically has two connecting pipes, one larger and one smaller, connecting the indoor and outdoor units to form a closed system. Refrigerant can circulate within both units. Copper pipes are usually preferred. However, existing trailer air conditioner external connecting pipe mechanisms simply connect one end of a connecting pipe to the connection port of the indoor or outdoor unit. If only the end is connected, air may leak from the connection point. Furthermore, prolonged vehicle travel and vibrations can cause the connection point to loosen, leading to leaks, breaking the closed system, and affecting the user experience. Therefore, this invention proposes a trailer air conditioner external connecting pipe mechanism to solve the above problems. Utility Model Content

It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Please see Figures 1 to 5 This utility model provides a technical solution: a trailer air conditioning external pipeline mechanism, including...

[0019] The main body of the pipe 1 has an internal connection mechanism 2 and an external connection mechanism 3 fixedly connected to its two ends.

[0020] The external mechanism 3 includes a positioning tube 4, a fixing groove 5 at the top of the positioning tube 4, a sealing ring 6 inside the fixing groove 5, a snap-fit ​​structure 7 fixedly connected to the top of the fixing groove 5, a threaded groove 8 on the side of the positioning tube 4, and a fixing threaded sleeve 9 threadedly connected to the side of the threaded groove 8. The set length of the fixing threaded sleeve 9 is twice that of the positioning tube 4. The sealing ring 6 is connected by compression fit between the internal mechanism 2 and the external mechanism 3 to form the first sealing layer, which protects the circulation inside the air conditioner's indoor and outdoor units, prevents leakage, and improves the stability of the air conditioner's operation.

[0021] The internal connection mechanism 2 includes a fixed tube 10, a snap-fit ​​block 11 fixedly installed on the top of the fixed tube 10, and the snap-fit ​​block 11 and the fixed groove 5 are in a hole-groove fit. A collar 12 is fixedly installed on the side of the fixed tube 10, and a sliding groove 13 is provided on the inner side of the collar 12. The sliding groove 13 is a slide-type structure design. A threaded groove 8 is provided on the side of the fixed tube 10, and the threaded groove 8 can be threadedly fitted with a fixed threaded sleeve 9. The fixed threaded sleeve 9 fastens the fixed tube 10 and the positioning tube 4 through threads, which is convenient for installation and disassembly, and can also play a docking and fixing role.

[0022] The snap-fit ​​structure 7 includes a mounting base 14, with a rotating shaft 15 fixedly connected to the top of the mounting base 14. A torque spring 16 is sleeved on the side of the rotating shaft 15, and a buckle 17 is connected to the side of the torque spring 16. A clamping plate 18 is fixedly connected to the top of the buckle 17, and a polyurethane film 19 is fixedly connected to the bottom of the clamping plate 18. The film is elastic, and its bottom is fixedly connected to the top of the positioning tube 4. The buckle 17 cooperates with the slide groove 13 of the slide-type structure design, which enables the fixing tube 10 and the positioning tube 4 to be fixedly engaged. Furthermore, the fixing groove 5 cooperates with the snap-fit ​​block 11 to perform docking and fitting, completing the guiding and fixing engagement of the fixing tube 10 and the positioning tube 4, which facilitates docking and installation.

[0023] The slide groove 13 can be fixed with the buckle 17, and the buckle 17 can be rotated and detached from the slide groove 13 through the rotating pipe body 1. The top of the fixed pipe 10 is fixedly connected with a dustproof net 20. Under the elastic power of the torque spring 16, the buckle 17 completes the sliding connection on the inside of the collar 12, forming a sealing film layer. The multi-layer sealing design prevents leakage of the internal circulation of the internal and external machines.

[0024] In practical use: First, the fixing groove 5 and the snap-fit ​​block 11 are engaged and fitted together. Then, the snap-fit ​​structure 7 is designed, and the snap-fit ​​17 is engaged with the sliding groove 13 of the slide-type structure, which enables the fixing tube 10 and the positioning tube 4 to be fixedly engaged. The snap-fit ​​17 drives the polyurethane film 19 to expand elastically. When the fixing tube 10 and the positioning tube 4 are engaged, the snap-fit ​​17 is driven by the elastic power of the torque spring 16 and completes the sliding connection on the inner side of the collar 12. The protrusion at the top of the snap-fit ​​17 quickly sinks into the bottom of the sliding groove 13 to complete the snap-fit ​​operation and prevent the fixing tube 10 and the positioning tube 4 from falling off. Under the action of the snap-fit ​​17, the polyurethane film 19 forms a sealing film layer on the inner side of the collar 12, forming a second sealing layer. Then, the fixing threaded sleeve 9 is used to fasten the fixing tube 10 and the positioning tube 4 with threads to complete the extension operation of the outer pipe. The multi-stage structure is tightly fixed, which improves the connection stability of the trailer air conditioning outer pipe.

[0025] 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.
