Of course, the bottom of the support wall can also be disposed at the same height as the rolling mechanism, so that the rolling mechanism and the rolling mechanism share the weight of the washing machine, reduce the weight of the supporting wall, and prolong the life of the supporting wall.

In order to save space, the rolling mechanism is disposed inside the fixing mechanism provided with the receiving cavity, thereby combining the rolling mechanism and the fixing mechanism into one. Compared with the conventional design in which the two are separately designed in the prior art, the present invention The washing machine mobile fixing device is compact in structure and takes up less space, and the part of the fixing mechanism contacting the ground is annular, occupying a large area, which is favorable for the stability of the washing machine.

In the present invention, the fixing mechanism can be set as a fixed connection structure, and the rolling mechanism is fixedly connected to the cover body of the fixing mechanism. At this time, the supporting wall can further include the fixed supporting wall 21 and the movable supporting wall 22, and the fixed support The wall 21 and the movable support wall 22 are combined to accommodate a rolling mechanism, and the movable support wall 22 is movably coupled to the fixed support wall 21 for adjusting the height of the cover 1 such that the rolling mechanism projects/receives the inside of the cover 1. When the rolling mechanism protrudes from the cover body 1, the washing machine can be moved to the position, and when the rolling mechanism is received inside the cover 1, the washing machine can be fixed. Specifically, the fixed support wall 21 and the movable support wall 22 are connected by screwing, that is, the inner wall of the fixed support wall 21 is provided with internal threads, and the outer wall of the movable support wall 22 is correspondingly provided with external threads. When it is necessary to move or fix the washing machine, the height of the cover body 1 can be changed simply by clockwise or counterclockwise twisting, so that the rolling mechanism protrudes/receives the inside of the cover body 1.

Of course, the part of the movable supporting wall contacting the ground can also be made of an elastic material, which is beneficial to the shock absorbing effect when the washing machine works.

Of course, the bolt cap can also be integrated with the screw.

Embodiment 2

Referring to FIG. 1 , FIG. 2 and FIG. 3 , in the second embodiment, the washing machine mobile fixing device comprises a rolling mechanism and a fixing machine. The components in which the rolling mechanism and the fixing mechanism are combined are connected in a detachable manner to facilitate replacement of the respective components in the event of wear or damage.

Specifically, the fixing mechanism includes a cover body 1 for accommodating a rolling mechanism. The top of the cover body 1 is screwed to a screw 3. The top of the screw 3 is screwed onto the body of the washing machine, and a screw cap is screwed on the screw 3. The bolt cap is free to move along the screw 3, and the bolt cap abuts against the lower surface of the washing machine body along the screw 3 to strengthen the connection structure between the screw 3 and the washing machine body, as further optimization, the screw The second bolt cap is also screwed up, and the second bolt cap is also free to move up and down along the screw. The second bolt cap is moved downward by the upper part of the screw and is disposed on the top shell of the cover body 1 to the screw. Further fixing to the structure of the lid body 1 prevents the lid body 1 from coming off the screw 3. The rolling mechanism includes a universal wheel 5 and a bracket 6 mounted on the cover 1 or at the bottom of the washing machine body. Preferably, the bracket is detachably and fixedly coupled to the top casing of the cover 1.

Of course, the screw 3 can also be connected to the bracket 6 through the upper casing of the cover 1, wherein the screw 3 is screwed to the cover 1, and the screw 3 is provided with two fasteners on both sides of the cover 1. In order to fix the cover 1, the fastener may of course be a bolt cap, and the height of the cover 1 can also be adjusted by moving two bolt caps. The bracket 6 can be screwed on the screw 3. At this time, the rolling mechanism can adjust the height and position of the rolling mechanism by twisting the bracket 6 clockwise or counterclockwise to realize the movement and positioning of the washing machine without using a single adjustment mechanism. The high and low position to achieve the movement and positioning of the washing machine.

In this embodiment, the relative position changes of the fixing mechanism and the rolling mechanism are realized by setting various structures, and the user can select different adjustment schemes to change the relative positions of the fixing mechanism and the rolling mechanism, thereby avoiding fatigue of the connecting structure due to repeated adjustment of a single structure. A problem that causes damage to the mobile fixture. At the same time, in the embodiment, each accessory is configured as a detachable connection structure, which is advantageous for replacing the worn accessory without causing a problem that the use performance of the washing machine is gradually decreased due to the inability to replace the accessory.

Embodiment 3

The third embodiment has the same feature as the first embodiment. The fixing mechanism of the washing machine mobile fixing device is also composed of a fixed supporting wall and a movable supporting wall. However, the adjustable supporting structure of the fixed supporting wall and the movable supporting wall in this embodiment is adjustable. It is not limited to the manner of being screwed. For example, the fixed support wall and the movable support wall of the present invention can be realized by a snap structure, wherein the fixed support wall and the movable support wall are respectively provided with two mutually cooperating portions on the mutually connected portions. a snap connection structure, wherein a snap mechanism causes the movable support wall portion structure to penetrate deeper or coincide with the fixed support wall portion structure, so that the entire fixing mechanism is shortened, the rolling mechanism protrudes from the cover body, and the other snap mechanism enables the movable support The wall is detached from the fixed support wall, so that the length of the entire fixing mechanism is lengthened, so that the rolling mechanism is received in the cover of the fixing mechanism.

Of course, a bottom-down chute can also be formed on the bottom annular side wall of the fixed support wall, the movable supporting wall The outer wall is provided with an outwardly protruding card protrusion, and the card convex card is slidably engaged in the sliding groove to change the distance between the movable supporting wall and the fixed supporting wall, so that the height of the entire cover changes. Grooves fixedly engaged with the card are respectively disposed at upper and lower ends of the sliding slot to position the movable supporting wall. Then, when the user needs to move or fix the washing machine, the user only needs to twist the movable supporting wall to change the groove which is convexly engaged with the card. This solution is simpler and more practical.

The fixing mechanism of the embodiment can set the height matching position of the buckle between the fixed supporting wall and the movable supporting wall, so that the adjusting manner of the fixing mechanism and the rolling mechanism is simpler and more convenient, and the user does not need to place the four corners of the washing machine. The position of the securing mechanism is adjusted to the same height to level the washing machine because the snap-fit structure has determined the adjustable position of the securing mechanism.

The above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the present invention, and any technology that is familiar with the present patent. Those skilled in the art can make some modifications or modifications to equivalent embodiments by using the technical content of the above-mentioned hints without departing from the technical scope of the present invention, but the technology according to the present invention does not deviate from the technical solution of the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments are still within the scope of the present invention.
