Description

The present invention relates to a refrigerant pipe joint.

The refrigerant is one of the most important elements of the air conditioning system, and the refrigerant circulates in the pipeline to effectively remove the heat of the internal environment and achieve the cooling effect. If the air conditioning system, especially the cooling of the vehicle, has a problem with cooling efficiency, it first detects whether the amount of refrigerant is sufficient and then detects other cooling devices. It is necessary to use a combination of refrigerant meters in the process of detecting and filling the refrigerant.

However, since the location of the vehicle cooling system is narrow and there are many parts around the pipeline, it is convenient and quick to connect the refrigerant meter to the refrigerant pipeline via a pipe joint. In addition, it may be necessary to remove peripheral parts in order to smoothly connect the pipeline, which is very troublesome.

A main object of the present invention is to provide a refrigerant pipe joint that can be effectively adjusted to an appropriate position and connected to a refrigerant pipe by a structure in which a rotating pipe rotates with respect to a pipe body.

In order to achieve the above object, the present invention provides a refrigerant-containing pipe joint containing a pipe body and a rotating pipe. The pipe body includes an internal passage and a first joint that communicate with each other, the first joint communicates with the pipeline of the refrigerant meter, and the rotating pipe is rotatably connected to the pipe body about the first rotating shaft. A second joint and a communication port are included, the communication port communicates with the internal space of the pipe body, and the second joint communicates with the refrigerant pipe so as to allow the refrigerant to pass through.
