[0002] Currently, in the HVAC repair field, the connectors of products such as refrigerant gauges and pressure gauges are mostly designed with fixed structures, resulting in inconvenient operation. Specifically, taking a certain digital display gauge as an example, its valve assembly includes a valve seat and multiple connectors installed below the same valve seat. The connectors are integrally molded, and each connector includes a connecting part and a closed oblique pipe connection part. The connecting part has a connecting channel, an upper pipe connection part, and a lower pipe connection part. In use, sometimes it is necessary to install one end of the flexible hose on the lower pipe connection part and the other end on the oblique pipe connection part. Due to the design goal of product miniaturization, the space between the connectors of some digital display gauges is small, leading to inconvenient operation. Summary of the Invention

[0011] The main connecting member is provided with a mounting groove, and the damping ring is located in the mounting groove; and / or,

[0012] The difference between the maximum outer diameter of the damping ring and the aperture of the rotating connecting member is 0.2-0.6 mm.

[0013] As an improvement, an anti-drop convex part is formed on the main connecting member, and a force-bearing part supported by the anti-drop convex part is formed on the rotating connecting member.

[0014] As an improvement, the lower end of the rotating connecting member is provided with a wrapping part that wraps the anti-drop convex part.

[0015] As an improvement, the lower end of the connecting passage is formed with a tool hole.

[0016] As an improvement, both the upper pipe connecting part and the lower pipe connecting part are provided with external threads.

[0017] As an improvement, the entire joint with the rotating connecting member is in a "L" shape or a "T" shape.

[0019] As an improvement to the digital display meter, all the joints are the aforementioned joints with a rotating connecting member; and / or,

[0020] The rotating connecting member is located below the valve seat, and the valve seat restricts the upward displacement of the rotating connecting member.

[0021] The beneficial effects of the joint with a rotating connecting member of the present utility model are: compared with the integrally molded structure in the prior art, the joint is divided into at least two components including the main connecting member and the rotating connecting member, and the rotating connecting member is rotatably arranged outside the main connecting member. When it is necessary to mount both ends of a hose to the same joint and the distance between adjacent joints is relatively short, the distance between the inclined pipe connecting part and the other joint can be increased by rotating the rotating connecting member, thereby facilitating the operation.

[0022] The digital display meter of the present utility model adopts the joint with a rotating connecting member of the present utility model, and has all the beneficial effects of the joint with a rotating connecting member of the present utility model. Brief Description of the Drawings
