Detailed ways

In order to facilitate the understanding of the application, the application will be described in a more comprehensive manner with reference to the relevant drawings. The drawings show preferred embodiments of the application. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of this application more thorough and comprehensive.

With reference to Figures 1 to 8, according to an embodiment of the present application, a supporting device is provided for supporting the outer tub of the washing machine during transportation of the washing machine. The support device includes a support body 10 which is connected to the outer washing machine. The outer side of the tub is in direct contact to support and dampen the outer tub of the washing machine. The support body 10 includes a first plate body 1 and a second plate body 2 that are relatively parallel and spaced apart. The first plate The body 1 and the second plate body 2 are connected by a height adjustment component. A support block 11 is provided on the side of the first plate body 1 away from the height adjustment component. The height adjustment component can change the first The distance between a plate 1 and the second plate 2, that is, under the action of the height adjustment component, the distance between the first plate 1 and the second plate 2 can be based on actual conditions. In this way, the contact between the support block 11 and the outer tub of the washing machine can be ensured, thereby ensuring the reliable support of the outer tub of the washing machine by the supporting device during the transportation of the washing machine. It is understandable that the support block 11 is in direct contact with the outer tub of the washing machine. Therefore, in the selection of specific materials, the support block 11 preferably adopts a flexible material, such as common foam, rubber, etc. Further, the support block 11 includes at least a first support block 111 and a second support block 112, and the first support block 111 and the second support block 112 are staggered along the first direction of the first plate body 1. Interval settings.

A first connecting rod 5 is connected between the cross hinge point of the first X cross structure and the cross hinge point of the second X cross structure so that the first X cross structure and the second X cross structure are The spacing is stable, thereby ensuring the reliability of the height adjustment component.

Further, the height adjustment assembly further includes a thread adjustment assembly 6 which can realize the folding or unfolding state of the folding link assembly through its own rotation.

As a specific implementation of the thread adjustment assembly 6, in an embodiment, the thread adjustment assembly 6 includes a second connecting rod 61 and a threaded rod 62, and the threaded rod 62 is connected to the second connecting rod 61. T-shaped connection and hinged connection between the threaded rod 62 and the second connecting rod 61, the second connecting rod 61 is connected to the first rod 41 and the third rod 43 and the first plate Between the slidably connected ends of the body 1, the first plate body 1 is further provided with a position locking block 13 on the side facing the second plate body 2. The position locking block 13 is configured with a threaded through hole 131, so The threaded rod 62 is threadedly connected to the threaded through hole 131; or, the second connecting rod 61 is connected to the sliding connection of the first rod 41 and the third rod 43 with the second plate 2 Between one end, the second plate body 2 is further provided with a position locking block 13 on the side facing the first plate body 1. The position locking block 13 is configured with a threaded through hole 131, and the threaded rod 62 is threaded. Connected to the threaded through hole 131. For the hinged connection between the threaded rod 62 and the second connecting rod 61, for example, the second connecting rod 61 is provided with a radially penetrating threaded through hole, and the threaded rod 62 and the second connecting rod 61 are threaded. When the threaded rod 62 is rotated, the second connecting rod 61 is forced to move along the axial direction of the threaded rod 62, thereby adjusting the gap between the first plate body 1 and the second plate body 2. For another example, the end of the threaded rod 62 is connected to the radial through hole of the second connecting rod 61 through a bearing, and in order to prevent the threaded rod 62 from being disconnected from the second connecting rod 61, the thread A flange is formed at the end of the tie rod 62 so that the threaded tie rod 62 and the second connecting rod 61 are fixed in the axial direction of the threaded tie rod 62 and can rotate freely in the circumferential direction.

In order to achieve the positional stability of the supporting device, in one embodiment, the supporting device further includes a base 7 on which a receiving groove 71 is configured, and the supporting body 10 can be accommodated in the receiving Slot 71. It is understandable that when the supporting device is in the material transfer process, the supporting body 10 does not need to support and dampen the outer tub of the washing machine. At this time, the supporting body 10 is in the storage state and can be completely contained in the storage. In the groove 71, that is, the highest point of the support body 10 in the stored state is not higher than the highest point of the base 7, for example, specifically, when the base 7 has surrounding walls, at this time When the support body 10 is in the receiving groove 71, the highest point of the support body 10 is not higher than the highest point of the vertical wall, and when the base 7 is a flat plate structure, the highest point of the support body 10 The point is not higher than the highest point of the flat structure, that is, not higher than the notch of the receiving groove 71. In this way, the problem of difficult stacking of supporting devices in the prior art can be effectively overcome.

Preferably, the card slot 72 and the receiving slot 71 are perpendicular to each other. When the card slot 72 and the receiving slot 71 are perpendicular to each other, the The area of the bottom wall of the slot 72 will be the largest, and its support for the second plate 2 is more stable.

It can be understood that, in order to ensure the structural strength of the support body, it is preferable that, except that the support block 11 is made of foam and other flexible materials, other structures such as the first plate body 1, the second plate The body 2 and the corresponding structure and the screw adjustment assembly 6 are made of metal materials. The base 7 is preferably made of foam material, so as to reduce the overall weight of the supporting device.
