Problems solved by technology

[0002] At present, the pipes of the indoor and outdoor units of household air conditioners are connected by using union nuts and pipe joints to connect the indoor evaporator and outdoor pipes. However, because the union nuts are exposed and easy to disassemble, there is a possibility of disassembly by the user or by mistake. Therefore, It will cause the leakage of refrigerant, and if the flammable refrigerant leaks, it will cause serious safety problems

Embodiment 1

[0042] Such as figure 1 and Figure 5 As shown, this embodiment provides an anti-disassembly assembly 1 for a connecting pipe 2, the connecting pipe 2 is provided with a pipeline connection part, and the anti-disassembly assembly 1 includes a fixing mechanism and a limiting mechanism; A fixed cavity 111 with one end opening is formed in the fixing mechanism, and the other end of the fixing mechanism relative to the opening is provided with a via hole 113 for the connecting pipe 2 to pass through, and the via hole 113 is connected to the fixed cavity. 111; the limiting mechanism is fixed in the fixed cavity 111, and the pipeline connection part is fixed in the limiting mechanism.

[0043] Such as figure 1 , figure 2 , Figure 5 and Figure 6 As shown, the anti-disassembly assembly 1 provided in this embodiment includes a fixing mechanism and a limit mechanism, and the pipeline connection part (such as the pipe joint 4 and the union nut 3) on the connecting pipe 2 is wrapp...

Embodiment 2

[0045] Such as Figure 1 to Figure 4 As shown, this embodiment provides an anti-disassembly assembly 1, which is used for connecting pipe 2, and the connecting pipe 2 is provided with a pipeline connection part, wherein the pipeline connection part can be a pipe joint 4 and a union nut 3, or It can be used as another pipeline connection mechanism, and the connecting pipe 2 can be a copper pipe, or a plastic pipe, steel pipe or other pipelines; preferably, the pipeline connection part in this application is a pipe joint 4 and a union nut 3, The connecting pipe 2 is mainly a copper pipe used in an air conditioner heat exchanger, that is, a copper pipe connected to an air conditioner evaporator or condenser.

[0046] Such as Figure 1 to Figure 4 As shown, the anti-disassembly assembly 1 provided in this embodiment includes a fixing mechanism and a limit mechanism, wherein the fixing mechanism is a sleeve 11 with one end open, and the other end of the sleeve 11 is provided with ...

Embodiment 3

[0054] The technical solution of this embodiment is substantially the same as that of Embodiment 2, that is, the sleeve 11 that is also open at one end is described in this embodiment, and the other end of the sleeve 11 is the through hole 113. The main difference is that, as Figure 5 to Figure 8 As shown, the limiting mechanism includes a buckle 13 disposed in the fixing cavity 111, and the buckle 13 is used to hold the pipeline connection portion tightly.

[0055] In this embodiment, the buckle 13 is used to hold and fix the pipeline connection, that is, the pipe joint 4 and the union nut 3 are tightly held by the buckle 13, or the union nut 3 is tightly held and fixed by the buckle 13; optional In this embodiment, the buckle 13 is used to hold and fix the union nut 3, that is, the buckle 13 is set in the gap between the union nut 3 and the pipe joint 4, and the union nut 3 is fastened to fix it. The union nut 3 further prevents users from disassembling the union nut 3 and ...

Abstract

The invention relates to the technical field of household appliances, in particular to an anti-disassembling assembly for a connecting pipe, a pipeline system and a household electrical appliance. The anti-disassembling assembly comprises a fixing mechanism and a limiting mechanism, a pipeline connecting part, such as a connecting pipe nut and a pipe joint on the connecting pipe is wrapped and fixed by the limiting mechanism, so that the pipeline connecting part is firmly fixed; due to blocking and fixing of the limiting mechanism, a user can not automatically detach the pipeline connecting part; and meanwhile, the limiting mechanism is fixed in a fixed cavity formed by the fixing mechanism, so that the user does not have space and gaps directly or adopts a tool to disassemble the limiting mechanism, the limiting mechanism is tightly fixed through the fixing mechanism, so that the double anti-disassembling effect is achieved, then the purpose of preventing the user from disassembling the pipeline connecting part is achieved, and the safety performance of the pipeline system is improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an anti-disassembly assembly for connecting pipes, a pipeline system and household appliances. Background technique [0002] At present, the pipes of the indoor and outdoor units of household air conditioners are connected by using union nuts and pipe joints to connect the indoor evaporator and outdoor pipes. However, because the union nuts are exposed and easy to disassemble, there is a possibility of disassembly by the user or by mistake. Therefore, It will cause leakage of refrigerant, and if flammable refrigerant leaks, it will cause serious safety problems. Contents of the invention [0003] (1) The technical problem to be solved by the present invention is: the existing outdoor unit of air conditioner has the risk of connecting nuts and pipe joints being dismantled or mistakenly disassembled by users. [0004] (2) Technical solution [0005] In order to sol...
