Description

Technical Field

[0001] The utility model relates to the technical field of pipe joint equipment, in particular to an air-conditioning pipe joint connection structure. Background Art

[0002] Air conditioning pipeline refers to the pipeline system used to transmit refrigerant and liquid or gas flow. It is an important component of the air conditioning system. Air conditioning pipeline is generally composed of multiple air conditioning pipes. These pipes are often connected using air conditioning pipe connectors. In the existing technology, air conditioning pipelines are generally made up of multiple groups of connections. After long-term use, the connections will become loose or even fall off, affecting the normal operation of the air conditioner. In addition, the single sealing mechanism has poor sealing effect and lacks the function of tightening the connections of the air conditioning pipe joints.

[0003] For example, the authorized patent document with application number CN202123389505.6 discloses a car air-conditioning pipe joint connection structure. Most of the existing connection structures are integrated, and the overall disassembly and assembly are inconvenient. When local parts are damaged, they often need to be replaced as a whole, which has high maintenance costs. At the same time, when the hose is in direct contact with it, it is easy to cause wear, thereby reducing the service life of the hose. A connecting mechanism is connected between the first hose and the second hose, and a sealing mechanism is installed at the end of the first hose and the second hose. The connecting mechanism can facilitate the user to quickly connect the first hose and the second hose, and the connecting mechanism can facilitate rapid disassembly and assembly as a whole through structural optimization. It is not only easy to replace local spare parts and reduce maintenance costs, but the sealing mechanism can increase the sealing performance between the hose and the traditional connection structure, and the tightening tube can also prevent the wear caused by direct contact between the hose and the traditional connection structure.

[0004] The above patent has a single sealing mechanism, which has a poor sealing effect and lacks the function of tightening the connection of the air-conditioning pipe joint. Therefore, we need to provide an air-conditioning pipe joint connection structure. Utility Model Content
