Considering that the fixed positions of different drums are different, the positions of the upper/lower drum tension spring seat and the upper/lower drum damper base 2 can be adjusted according to the actual conditions of the drums; the purpose of the reinforcement plate 5 is to enhance the strength of the frame, so Not limited to the middle position mentioned in the embodiment, it can also be fixed in other reasonable positions that can strengthen the frame; the function of the U-shaped seat 6 of the shock absorber and the tension spring seat is to cooperate with the tension spring through the shock absorber To achieve the vibration reduction effect of the whole machine, the number of the U-shaped seat 6 and the tension spring seat of the shock absorber is not limited to the 4 mentioned in the embodiment, and can be reasonably changed according to the actual vibration effect;

In the frame structure of the multi-tub washing machine of the present invention, the fixing methods among all the components are not limited to screw fixing, but also include welding, riveting and other fixing methods.

Beneficial effects:

The utility model has at least the following beneficial effects:

1. By using the one-piece frame structure of the one-piece back-shaped base 2/top basket/beam 4, the reinforcing plate 5 is reasonably added to effectively improve the frame strength of the multi-tub washing machine;

2. The upper and lower barrels are separately provided with tension spring seat and shock absorber U-shaped seat 6, which should be reasonably selected according to the actual vibration effect, thereby reducing the vibration generated by the multi-barrel washing machine during the joint operation;

3. The frame is mostly composed of one-piece structure, the structure is simple, the mold development cost is reduced, the operation is convenient, and the assembly process is simple;

4. Increase the use of the foot structure, and at the same time provide support for the upper, middle and lower buckets, so that when the three buckets work at the same time, they can also ensure stability and firmness, reduce the impact of the vibration of multiple buckets on the frame, and improve the support stability of the multi-bucket washing machine frame.

Exemplary embodiments of the present disclosure have been specifically shown and described above. It should be understood that this disclosure is not limited to the details of construction, arrangements, or implementations described herein; on the contrary, this disclosure is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
