Embodiment Construction

[0033] In order to understand the above-mentioned purpose, features and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0034] Such as Figure 2 to Figure 8 As shown, one embodiment of the present invention provides an anti-disassembly union nut assembly, and the anti-disassembly union nut includes a union nut 1, an auxiliary nut 2 and a limiting mechanism;

[0035] The auxiliary nut 2 is provided with a plurality of ratchets 21 made of elastic material, one end of the ratchet 21 is connected to the end surface on one side of the auxiliary nut 2, and the other end faces away from the side of the auxiliary nut 2. one side extension;

[0036] Said union nut 1 is provided with a...

Abstract

The invention relates to the technical field of domestic appliances, in particular to a disassembly-prevention union nut assembly, a pipeline system and a domestic appliance. The disassembly-prevention union nut assembly provided by the embodiment comprises a union nut, an auxiliary nut and a limiting mechanism, the auxiliary nut is provided with ratchets capable of generating elastic deformation,and the union nut is provided with slide grooves matched with the ratchets; the auxiliary nut is fixed to the union nut through the limiting mechanism, and the limiting mechanism can limit axial movement of the auxiliary nut but cannot limit rotation of the auxiliary nut. Compared with existing methods for achieving disassembly prevention of springs, clamp springs and auxiliary nuts, few parts are involved, the manufacturing cost and assembly labor cost can be reduced, few assembly working procedures are needed, assembly is convenient, and the assembly efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an anti-disassembly union nut assembly, a piping system and a household appliance. Background technique [0002] At present, the connecting pipes of the indoor and outdoor air conditioners of household air conditioners are connected by using union nuts and pipe joints to connect the indoor evaporator and the outdoor connecting pipes. It will lead to the leakage of refrigerant, and if the flammable refrigerant leaks, it will cause serious safety problems; if figure 1 As shown, the auxiliary nut 2, the spring 3 and the circlip 4 are used to cooperate with the connecting nut 1 to realize the anti-disassembly function; since the outer surface of the connecting nut 1 is a smooth cylindrical surface, it can only be driven by the auxiliary nut 2 to rotate the connecting nut 1. The connection nut 1 is rotated to realize the threaded connection with the connecting pipe; ther...
