Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioning pipe connection technology, and in particular to a portable multi-functional air conditioning pipe connection and fastening device. Background Technology
[0002] Heating, ventilation and air conditioning (HVAC) is an air conditioner that has the functions of heating, ventilation and air conditioning. The main functions of HVAC include these three aspects.
[0003] Existing pipe connection devices use threads and bolt holes for fixing at the connection points, which leaves gaps at the connection points, affecting the sealing degree of the connection points and making them prone to leakage, as well as vibrations generated during the air conditioning pipes' air transport and delivery processes.
[0004] Therefore, it is necessary to provide a portable, multi-functional air conditioning pipe connection and fastening device to solve the above-mentioned technical problems. Utility Model Content
[0005] This invention provides a portable, multifunctional air conditioning pipe connection and fastening device, which solves the problems in the background art.
[0006] To solve the above-mentioned technical problems, this utility model provides a portable multifunctional air conditioning pipe connection and fastening device, including an air conditioning pipe body, a first connecting pipe, and a second connecting pipe. A first sealing cap is provided through one end of the first connecting pipe, and a first annular airbag is snapped into the inside of the first sealing cap. A second sealing cap is provided through one end of the second connecting pipe, and a second annular airbag is snapped into the inside of the second sealing cap. The outer surface of the first sealing cap has external threads, and the inner wall of the second sealing cap has internal threads. By using the first connecting pipe, the first connecting cap, the second connecting pipe, the second connecting cap, the first annular airbag, and the second annular airbag in combination, it is convenient to improve the connection and fastening of the air conditioning pipe. The sealing at the connection of the main body of the air conditioning duct allows for the following operation: first, the first and second connecting pipes are fitted onto the outside of the two main air conditioning duct bodies; then, the first and second annular airbags are fitted onto them; finally, the two main air conditioning duct bodies are spirally connected; and then the first and second sealing caps are spirally closed. During the closing process, the first and second annular airbags are squeezed against each other, thus ensuring a tight fit between the first and second annular airbags and the main air conditioning duct body, further improving the sealing at the connection. Moreover, the combination of external and internal threads makes it easy to connect the first and second sealing caps when not in use, facilitating their transport and preventing loss.
[0007] Preferably, the inner diameters of the first connecting pipe and the second connecting pipe are equal to the outer diameters of the air conditioning duct bodies at both ends. By setting the inner diameters of the first connecting pipe and the second connecting pipe to be equal to the outer diameters of the air conditioning duct bodies at both ends, their sealing performance is further improved.
[0008] Preferably, the inner diameters of the first and second annular airbags are equal to the outer diameters of the air conditioning duct bodies at both ends. By setting the inner diameters of the first and second annular airbags to be equal to the outer diameters of the air conditioning duct bodies at both ends, it is easier to improve the sealing performance between them and the air conditioning duct bodies during subsequent compression.
[0009] Preferably, the first connecting pipe and the first sealing cap are integrally formed, which facilitates improved sealing performance.
[0010] Preferably, the second connecting pipe and the second sealing cap are integrally formed, which facilitates the improvement of their sealing performance.
[0011] Preferably, the first connecting pipe and the second connecting pipe are made of PVC. By making the first connecting pipe and the second connecting pipe of PVC, their service life can be improved.
[0012] Compared with related technologies, the portable multifunctional air conditioning pipe connection and fastening device provided by this utility model has the following advantages:
[0013] Compared with existing technologies, this portable multi-functional air conditioning pipe connection and fastening device, through the coordinated use of a first connecting pipe, a first connecting cap, a second connecting pipe, a second connecting cap, a first annular airbag, and a second annular airbag, facilitates improved sealing at the connection points of the air conditioning pipe bodies. During operation, the first and second connecting pipes are first fitted onto the outer sides of the two air conditioning pipe bodies, followed by the first and second annular airbags. The two air conditioning pipe bodies are then spirally connected, and the first and second sealing caps are spirally closed. During the closing process, the first and second annular airbags are compressed against each other, ensuring a tight fit between the first and second annular airbags and the air conditioning pipe bodies, further improving the sealing at the connection point. Furthermore, the combination of external and internal threads allows the first and second sealing caps to be connected when not in use, facilitating portability and preventing loss.
