Description

Technical Field

[0001] The invention relates to the technical field of pipeline connection, in particular to a compact air-conditioning pipeline connector. Background Art

[0002] Air conditioning systems have been widely used in people's daily lives. They can adjust the indoor temperature to make the indoor temperature environment more comfortable. They are commonly used electrical appliances in modern life. Air conditioning systems are usually composed of an outdoor unit and an indoor unit, and the outdoor unit and the indoor unit are connected by pipes to facilitate the outdoor unit to exchange heat with the indoor unit and adjust the indoor temperature. During the air conditioning installation process, due to different building exterior wall structures, the different directions of the air conditioning pipes are determined. If the air conditioning pipe is too long or the direction of the pipe is not conducive to installation, the pipe needs to be connected, extended and turned. Therefore, the pipe needs to be connected again.

[0003] After extensive searching, the prior art was found: Publication No. CN107237930A discloses an air conditioning pipe connector, which solves the problems of inconvenient operation, high risk factor, easy leakage and easy generation of impurities in oxygen welding connection. The air conditioning pipe connector includes a jacket and a clamping sleeve, and the jacket is provided with sealing parts at both ends. The clamping sleeve is arranged on the sealing part and can deform the sealing part under the action of external force. The jacket is provided with a through hole for the air conditioning pipe to pass through. The above technical solution can well solve the problems in the prior art.

[0004] In summary, most of the existing air-conditioning pipe connections use connectors or welding. Since there are many types of connectors on the market, and welding requires additional welding equipment, the operation flexibility is poor. Although the connector connection method can ensure that the air-conditioning pipe has a reliable connection stability and airtightness in the short term, it will cause the air-conditioning pipe to fall off or the connection tightness to be affected if it is pulled by external force or material aging.
