Preferably, in the present embodiment, the first mounting seat 10 is installed at the left edge of the drawer type processing barrel 1, the second mounting seat 20 is installed at the right edge of the drawer type processing barrel 1, the first rotating seat 12 and the second rotating seat 22 rotate when the drawer type processing barrel 1 is pulled, and the link structure 30, the second telescopic structure 40 and the first telescopic structure 60 rotate reversely when the drawer type processing barrel 1 is pushed, and the link structure 30 and the second telescopic structure 40 are shortened.

Moreover, when the drawer-type processing barrel 1 is pushed to the innermost position of the frame 2, the link structure 30, the second telescopic structure 40 and the first telescopic structure 60 form a smaller included angle with the back of the drawer-type processing barrel 1, so that the occupied space can be reduced, the gap between the back of the drawer-type processing barrel 1 and the frame 2 can be reduced, and the size of the frame 2 and the whole machine can be smaller.

In this embodiment, the drawer type tub 1 includes a drawer structure and a pulsator washing tub disposed therein, the water inlet line of the pulsator washing tub is disposed on the link structure 30, the water discharge line is disposed on the second telescopic structure 40, or the water inlet line 70 is disposed on the first telescopic structure 60. Preferably, the connecting parts of the water inlet pipeline and the water discharge pipeline and the drawer-type treatment barrel 1 are corrugated pipes, so that the connecting parts are prevented from being pulled or excessively worn when the pipelines move.

The utility model discloses a telescopic pipeline arrangement structure realizes the installation to the pipeline or the circuit of connecting between two moving parts to avoid removing the influence to pipeline and circuit, can also realize that the pipeline separates and improve the security, and this mounting structure simple to operate, compact structure can be used to narrow space, and application scope is wider.

Exemplary embodiments of the present disclosure are specifically illustrated and described above. It is to be understood that the present disclosure is not limited to the precise arrangements, instrumentalities, or instrumentalities described herein; on the contrary, the disclosure is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
