The invention provides an anti-dismantle union nut, an anti-dismantle pipe joint device and an air conditioner. The anti-dismantle union nut comprises a nut body and a screwing member, and the nut body has a internal thread fitting with a pipe joint and a conical surface which is assembled with a bell mouth of a connecting pipe; a hollow cavity is formed in the screwing member, an opening penetrating in the axial direction is formed in the screwing member, and the width of the opening in the circumferential direction of the screwing member is greater than the outer diameter of the connecting pipe so that the screwing member can be clamped on the connecting pipe from the opening or come off the connecting pipe from the opening; and the nut body can be sleeved with the screwing member, a transmission matching structure is arranged between the screwing member and the nut body, and the screwing member transmits a tightening torque to the nut body through the transmission matching structure. According to the anti-dismantle union nut, after the assembling is completed, the screwing member is taken off from the connecting pipe through the opening on the screwing member, so that the anti-dismantle requirement of the flammable refrigerant pipeline is fulfilled and the screwing member can be conveniently separated from the entire pipe connecting system.
Description
technical field [0001] The invention relates to the technical field of air conditioners, and more specifically, to an anti-dismantle connecting nut, an anti-dismantle connecting device and an air conditioner. Background technique [0002] At present, split-type air conditioners usually use pipe joints and union nuts to connect the pipelines of the indoor unit and the outdoor unit. And for air conditioners that use flammable refrigerants, in order to avoid safety accidents caused by refrigerant leakage due to disassembly by mistake, the relevant standards stipulate that detachable joints are not allowed on the indoor side. [0003] In order to meet the non-removable requirements of the pipe connection device, anti-disassembly pipe joints or union nuts are designed in the related art. However, the assembly structure is complicated, and it will be separated from the pipe joint or union nut while meeting the anti-disassembly requirements. Some parts remain in the pipeline syste...
