Air conditioner and anti-disassembly connection device

Abstract

The invention provides an anti-demounting connecting pipe device. A pipe connector comprises a first external hexagonal segment and an external thread segment. A connecting pipe nut comprises a second external hexagonal segment. The external thread segment is forwardly locked in the second external hexagonal segment. Two end faces between the first external hexagonal segment and the second external hexagonal segment are provided with a plurality of first wedged teeth, arranged in a radial form, and a plurality of second edged teeth, arranged in a radial form, respectively; an elastic washer is disposed between the two end faces; two opposite sides of the elastic washer are provided with a plurality of first stop faces and a plurality of second stop faces. When the pipe connector and the connecting pipe nut are reversely screwed, the first stop faces are abutted to the first wedged teeth, and the second stop faces are abutted to the second edged teeth. The first and second stop faces of the elastic washer are abutted to the first and second wedged teeth, respectively; accordingly, mistaken demounting is avoided, leakage of coolant in the air conditioner is avoided, and life safety of users is guaranteed. The invention further provides an air conditioner comprising the anti-demounting connecting pipe device.

Description

technical field [0001] The invention belongs to the technical field of connection of air-conditioning pipelines, and in particular relates to an anti-disassembly connection device and an air conditioner using the anti-disassembly connection device. Background technique [0002] At present, pipe joints and auxiliary nuts are used to connect the pipelines of the evaporator and the outdoor unit on the indoor side of the household split air conditioner. The outer surface of the existing auxiliary nut is a prismatic surface with a force-applying cut surface. The pipe joint is generally an integral pipe joint, which is mainly composed of a threaded section and a prism section. When a clockwise torque is applied to the prism section, the thread section and the prism section The prismatic segments rotate together to form a tight fit with the auxiliary nut to form a sealing surface. However, when a counterclockwise torque is applied to the prism section, it also drives the threaded ...
