Embodiment 3

This embodiment also has the following technical features based on the above-mentioned first and second embodiments:

As shown in FIGS. 1 to 8 , in this embodiment, a connecting rod 17 is connected to the left and right sides of the motor 2 respectively. The two connecting rods 17 are arranged in parallel and are connected to the motor bracket 1 respectively. The adjusting mechanism is connected with the motor bracket 1 . The connecting rod 17 hangs the motor 2 in the motor bracket 1, so that the motor bracket 1 protects the motor 2 left and right, so that when the washing machine is working, the motor 2 is fixed in the middle of the motor bracket 1, and the motor is in motion. 2 There is no interference in normal operation and will not collide with any part of the box.

In the present embodiment, the front and rear sides of the motor bracket 1 are respectively provided with downwardly vertically bent and parallel flanges, and the flanges and the motor bracket 1 form a hollow shell with an opening facing downward. Both ends of the connecting rod 17 pass through the flanges on the corresponding side respectively, at least one piercing end of any connecting rod 17 is connected to the motor bracket 1 through the above-mentioned adjusting mechanism, and the piercing ends of the connecting rod 17 are respectively fixed with a third nut 6 .

In this embodiment, any side flange of the motor bracket 1 is provided with an arc-shaped through hole 5 for any connecting rod 17 to pass through, and the circumferential extension length of the arc-shaped through hole 5 is greater than the radial dimension of the connecting rod 17 , the connecting rod 17 can slide relative to the motor bracket 1 along the circumferential direction of the arc-shaped through hole 5 . The sliding distance of the arc-shaped through hole 5 has a first set value, and the arc length of the first set value is at least 1cm. The first set value also needs to consider the longest slack state of the belt 16, and the belt 16 that is too long is easy to slip. Optimally, 1cm is the most suitable length, and the first setting value can make the belt 16 reach the most initial state. The first set value can also meet the requirements of other embodiments to open the mold into different arcs, so as to meet the requirements of different embodiments. Preferably, one end of the connecting rod 17 is slidable and the other end is fixed, and the sliding distance of the sliding end is an arc shape centered on the fixed end.

In this embodiment, there is a third nut 6 that is closely attached to the front flange 3. The diameter of the third nut 6 is larger than the radial dimension of the connecting rod 17. It does not slide, and indirectly prevents the motor 2 from moving down by its own gravity. At the same time, the third nut 6 also plays a role in fixing the adapter 11 , because the adapter 11 is clamped between the front flange 3 and the third nut 6 . In addition, through the adapter 11, the third nut 6 increases the contact area with the front flange 3, making it firmer to the connecting rod 17. In normal industrial use, it is necessary to check whether the third nut 6 is loose from time to time, because the tightness of the third nut 6 directly affects the position of the motor 2. When the third nut 6 is loose, the connecting rod 17 It will slide along the arc-shaped through hole 5, so that one end of the motor 2 will also move along with it.

In the motor installation structure described in this embodiment, when the belt 16 is loose, the maintenance personnel only need to adjust the position of the motor 2 at one end of the arc-shaped through hole 5, and the other end of the motor 2 is fixed and does not need to be adjusted. It is necessary to loosen the first nut 8, the second nut 7 and the third nut 6 with a wrench, and then the connecting rod 17 will slide down along the arc-shaped through hole 5, and will also drive the motor 2 to move downward. One end presents an arc-shaped movement track around the fixed axis relative to the original position. The advantage of this is that the motor bracket 1 can be more stable, and the belt 16 will not be offset. The nut 7 and the third nut 6 are tightened, thus completing the tightening process of the belt 16 . And the operation process can be completed by only one person, which saves costs and reduces the labor of maintenance personnel.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Without departing from the scope of the technical solutions of the present invention, when the technical content indicated above can be used to make some changes or modifications to equivalent examples of equivalent changes, the implementations in the above-mentioned examples can be further combined or replaced, but any Departing from the content of the technical solution of the present invention, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention still fall within the scope of the solution of the present invention.
