Description

Automobile air conditioner pipeline joint Technical Field The utility model relates to the technical field of air conditioner pipeline connectors, in particular to an automobile air conditioner pipeline connector. Background The automobile air conditioner pipeline joint is an important element for connecting all parts of an air conditioner system, the sealing performance of the automobile air conditioner pipeline joint directly influences the operation efficiency of the air conditioner system, and the traditional pipeline joint is easy to have the problem of poor sealing during installation, so that refrigerant leakage is caused, and the air conditioner performance is influenced. The traditional joint structure usually adopts a fixed sealing ring, but is easy to age and deform after long-term use, so that the sealing is invalid, the sealing of the traditional joint is achieved by extruding the end faces through the upper end and the lower end, the sealing effect is poor, the joint needs to be replaced once the sealing between the joints leaks, and the maintenance and overhaul cost is increased. Therefore, there is a need for an automotive air conditioning duct joint that has better sealing properties and is easy to maintain. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides the automobile air conditioner pipeline connector, which solves the sealing problem of air conditioner pipeline connector connection, can improve the sealing effect by adding the movable sealing ring, and is convenient to maintain and overhaul, and the sealing gasket and the fixing ring can be movably detached. The automobile air conditioner pipeline connector comprises a pipe body and a connector, wherein the pipe body is fixedly connected with the connector, a connecting pipe is fixed at the lower end of the connector, a screw rod penetrates through one side of the connector and is fixedly connected with the lower end connecting end in a threaded manner, a movable groove with an L-shaped cross section is formed in the inner side surface of the lower end of the connector, a gasket is fixed at the upper end of the inner part of the movable groove, a movable sealing ring is movably arranged in the movable groove, and the upper end of the movable sealing ring is L-shaped and is overlapped with the movable groove in a staggered manner. Furthermore, the lower end of the movable sealing ring can be deformed to form a seal, and the movable sealing ring is arranged around the outer ring of the lower end of the joint. Further, a packing ring is fixed at the lower end of the outer side of the connector, the lower end of the packing ring is arranged beyond the edge of the lower end of the connector, and the packing ring is sleeved on the outer side of the lower end connecting end. Further, a sealing gasket is arranged at the inner edge of the lower end of the wrapping ring, and the sealing gasket abuts against the outer edge of the lower end connecting end and deforms. Further, the outer side end of the sealing gasket is fixed with a fixing ring, and the fixing ring is clamped with the inner side end of the packing ring. Further, the screw is used for fastening the joint and the lower end connecting end, and provides a stable fixing effect through threaded connection. The utility model provides an automobile air conditioner pipeline joint.
