As shown in fig. 1 to 3, in a first embodiment of the present invention, the movable base 100 includes a base body 110, a roller mount 120, a roller 130, a driving device 140, and an optional leg 150. The roller mount 120 is pivotally mounted to the base body 110. The roller 130 is rotatably mounted to the roller mount 120. The driving device 140 is configured to drive the roller mounting base 120 to swing relative to the base body 110, so as to adjust an included angle between the roller mounting base 120 and the base body 110, so that the roller 130 moves toward or away from the base body 110, thereby adjusting a distance between the base body 110 and the bearing surface 200 (as shown in fig. 6 and 7). The legs 150 are threadedly coupled with the base body 110. The legs 150 are movable away from the base body 110 when twisted and are capable of abutting against the bearing surface 200 (shown in fig. 6 and 7) to jack up the base body 110 to disengage the rollers 130 adjacent to the legs 150 from the bearing surface 200 (shown in fig. 6 and 7).

With continued reference to fig. 1 to 3, four corners of the base 100 are respectively provided with a roller mounting seat 120, and each roller mounting seat 120 is respectively corresponding to one roller 130 and one driving device 140. In addition, those skilled in the art can also appropriately adjust the installation positions and the number of the roller mounting seats 120 on the base 100 and appropriately adjust the number of the rollers 130 corresponding to each roller mounting seat 120 according to the needs. For example, three roller mounts 120 are provided for the base 100, and the three roller mounts 120 are disposed right in front of, left behind, and right behind the base 100, respectively. Further, those skilled in the art can also adjust the shape of the base 100 according to the distribution of the roller mounting seats 120. Illustratively, if all of the roller mounts 120 are distributed in a triangle, the shape of the base 100 is set to be a triangle. If all the roller mounting seats 120 are distributed in a tetragon shape, the shape of the base 100 is set in a tetragon (tetragon shape). If all of the roller mounts 120 are distributed in a pentagon shape, the shape of the base 100 is set to a pentagon shape.

As shown in fig. 1, the base body 110 is provided with a rotation shaft clamping groove 111 and a mounting cavity 112. The shaft clamping groove 111 is used for fixing the roller mounting seat 120, and the mounting cavity 112 is used for mounting the driving device 140.

As shown in fig. 4 to 7, the rotation shaft 121 of the roller mount 120 is mounted into the rotation shaft catching groove 111, and the rotation shaft 121 is substantially parallel to the horizontal plane so that the roller mount 120 can swing up and down around the rotation shaft.

With continued reference to fig. 4-7, the drive device 140 includes a first drive member 141 and a second drive member 142 drivingly connected together. The first driving member 141 is connected to the base body 110, and the second driving member 142 is connected to the roller mounting base 120. The first driving member 141 and the second driving member 142 are configured to be relatively movable to drive the roller mount 120 to swing with respect to the base body 110.

As shown in fig. 5, the first driving member 141 includes a threaded hole 1411 and an operating portion 1412, and the second driving member 142 includes a threaded post 1421. The threaded bore 1411 mates with a threaded post 1421. The operation portion 1412 is a column exposed at the front side of the base body 110. As shown in fig. 5, the operation portion 1412 is a hexagonal cylinder. Further, the operator 1412 may be provided with any other possible structure having a non-circular cross section, such as a triangular prism, an elliptic prism, a quadrangular prism, or the like, as necessary. Preferably, the first driving member 141 is a bolt having a threaded hole 1411.

In addition, the operating portion 1412 may be provided as a sink exposed to the front side of the base body 110 as needed by those skilled in the art, and the cross section of the sink is non-circular, such as a hexagonal sink, a triangular sink, an elliptical sink, a rectangular sink, etc.

With continued reference to fig. 5, the second drive member 142 is generally L-shaped, with a section of the second drive member 142 having a threaded post 1421 being referred to herein as a threaded section and a section of the second drive member 142 having no threaded post 1421 being referred to herein as a connecting section for ease of illustration. The second driving member 142 is pivotally coupled to the roller mount 120 through the connection section.

As shown in fig. 6 and 7, when the operating portion 1412 is operated, the first driving member 141 is driven to rotate, and thus the screw post 1421 is moved in a direction to extend into or out of the screw hole 1411, to change the lengths of the first driving member 141 and the second driving member 142, thereby driving the roller mount 120 to swing with respect to the base body 110.

In addition, in other embodiments of the present invention, a threaded post may be provided on the first driving member 141 and a threaded hole matching the threaded post may be provided on the second driving member 142 as required by those skilled in the art.

The method of use and the principle of operation of the drive device 140 will now be described in detail with reference to fig. 6 and 7.

When one of the rollers 130 of the base 100 is separated from the carrying surface 200 as shown in fig. 6 and suspended, an operator screws (specifically, may use a wrench) the operating portion 1412 to screw the threaded post 1421 of the second driving member 142 into the threaded hole 1411 of the first driving member 141, so that the lengths of the first driving member 141 and the second driving member 142 are shortened, and the roller mount 120 is rotated counterclockwise as shown in fig. 6. The roller 130 is gradually moved closer to the bearing surface 200 by the roller mount 120 until it abuts against the bearing surface 200. As the operator continues to twist the operating portion 1412, the roller mounting base 120 gradually lifts up its corresponding portion of the base 100.

When a portion of the base 100 corresponding to the roller 130 is higher, the operator reversely screws the operating portion 1412 to screw the screw post 1421 of the second driving member 142 out of the screw hole 1411 of the first driving member 141, thereby lengthening the length of the first driving member 141 and the second driving member 142 and further rotating the roller mount 120 clockwise as shown in fig. 6. In this process, the roller 130 is always abutted against the bearing surface 200 due to the gravity of the base 100. When the pressure between the roller 130 and the bearing surface 200 is zero, the roller 130 may be separated from the bearing surface 200 as the operating portion 1412 continues to be screwed.

It can be seen that the roller mount 120 is forced to swing mainly by the pulling force of the driving device 140 and the gravity of the base 100.

Further, although not shown in the drawings, in order to facilitate the relative movement between the first driving member 141 and the second driving member 142, a person skilled in the art may fill the screw hole 1411 with grease as necessary. And when the roller 130 abuts against the bearing surface 200, the threaded hole 1411 is inclined downward, so that the grease in the threaded hole 1411 flows to the threaded post 1421 under the action of self gravity, thereby lubricating the threads between the threaded post 1421 and the threaded hole 1411. As will be appreciated by those skilled in the art, since grease is sticky, the threads that engage each other will adhere to the grease during the relative movement of the first drive member 141 and the second drive member 142.

With continued reference back to fig. 1-3, the base 100 includes two feet 150, the two feet 150 being disposed on a front side of the base 100 and each corresponding to one of the roller mounts 120. Furthermore, the person skilled in the art can arrange the feet 150 in any other feasible number as desired. Such as one, three, four, etc.

In the first embodiment of the present invention, when the base 100 needs to be moved, the leg 150 is screwed forward to separate the leg 150 from the bearing surface 200 so that the roller 130 adjacent to the leg 150 abuts against the bearing surface 200. When the base 100 does not need to be moved, the legs 150 are reversely screwed to make the legs 150 abut against the bearing surface 200, and the base body 110 is lifted up, so that the rollers 130 close to the legs 150 are separated from the bearing surface 200.

The assembly process of the base 100 will be briefly described with reference to fig. 1, 5 to 7.

When the base 100 is assembled, the roller mounting seat 120 and the roller 130 are mounted together, and then the roller mounting seat 120 is mounted from below the base body 110, so that the roller mounting seat 120 is embedded into the rotating shaft clamping groove 111 with the downward opening. Then, the second driving member 142 is inserted from the mounting cavity 112 onto the roller mount 120, and then the first driving member 141 is passed through a hole provided on the front side of the base body 110, and the first driving member 141 and the second driving member 142 are screwed together. Finally, the legs 150 are screwed into threaded holes (not shown) in the base body 110.

It should be noted that the foregoing assembly sequence of the base 100 is not fixed, and one skilled in the art may adjust the assembly sequence between the components of the base 100 according to the actual situation.

Based on the foregoing description, it will be appreciated by those skilled in the art that in the first embodiment of the present invention, the roller mount 120 is driven to swing by the driving device 140 so that the corresponding roller 130 can be close to or far from the base body 110, thereby achieving the adjustment of the height of each roller 130. Therefore, the base 100 of the present invention can not only be moved by the roller 130, but also adjust the distance between the base body 110 and the bearing surface 200 by the driving device 140, so that the base 100 can be prevented from being skewed.

Further, in the first embodiment of the present invention, the provision of the legs 150 also prevents the movement of the base 100, and fixes the base 100.

Still further, by disposing all the operating portions 1412 of the driving devices 140 on the front side of the base 100, the adjustment of the driving devices 140 by the operator is facilitated, and the user experience is optimized.

The base 100 in the second embodiment of the present invention will be described with reference to fig. 8.

As shown in fig. 8, the base 100 in the second embodiment of the present invention further includes a locking cap 160, as compared to the first embodiment. The locking cap 160 serves to lock the driving device 140 to prevent the driving device 140 from being loosened by vibration, thereby causing the roller mount 120 to swing. Specifically, the locking cap 160 is provided with a magnet 161 and an anti-slip structure 162. The anti-slip structure 162 is disposed on a side of the locking cap 160 facing the base body 110. And the locking cap 160 can be fitted with the operation portion 1412 of the driving device 140. For example, the locking cap 160 is fitted with the operating portion 1412 in the form of a hexagonal column shown in fig. 5 and 6 through a hexagonal hole structure shown in fig. 8.

With continued reference to fig. 8, corresponding to the locking cap 160, the base body 110 is provided with a non-slip engagement structure 113, and the non-slip engagement structure 113 is matched with the non-slip structure 162. Optionally, both the anti-slip feature 162 and the anti-slip mating feature 113 are anti-slip threads. The portion of the base body 110 corresponding to the locking cap 160 is provided in a form capable of being attracted by the magnet 161. For example, an iron piece is provided at a position of the base body 110 corresponding to the locking cap 160.

In the assembled state, the locking cap 160 is detachably mounted with the operating part 1412, the locking cap 160 is adsorbed to the base body 110 through the magnet 161, and thus the anti-slip structure 162 is mated with the anti-slip mating structure 113 to prevent the first driving member 141 from being loosened.

When the driving device 140 needs to be adjusted, the operator only needs to pull the locking cap 160 off the operation portion 1412.

Based on the foregoing description, it will be appreciated by those skilled in the art that in the second embodiment of the present invention, the base 100 can lock the driving device 140 by the locking cap 160, preventing the driving device 140 from abnormal swing of the roller mounting 120, thereby ensuring the stability of the base 100 in long-term use.

The base 100 in the third embodiment of the present invention will be described with reference to fig. 9.

As shown in fig. 9, in the third embodiment of the present invention, the structure of the base body 110 is changed correspondingly, compared with the first and second embodiments. Specifically, the base body 110 replaces the mounting cavity 112 with the relief structure 114.

In the process of assembling the base 100, the roller mounting base 120 is similarly inserted into the rotation shaft clamping groove 111 from the bottom side of the base body 110, so that the rotation shaft 121 is embedded. The operator then inserts the second drive member 142 from the evasion structure 114 into the roller mount 120.

As can be seen from fig. 9 and 1, in the third embodiment of the present invention, the avoidance structure 114 can visualize the installation process of the second driving member 142, and improve the assembly efficiency of the operator.

A base 100 in a fourth embodiment of the present invention will be described with reference to fig. 10.

As shown in fig. 10, in comparison with the first, second, and third embodiments, in the fourth embodiment of the present invention, the driving device 140 includes a screw 143 and a screw nut 144 that are engaged, the screw 143 being rotatably and axially fixedly coupled together with the base body 110, the screw nut 144 being pivotally coupled with the roller mount 120. Further, the screw 143 includes a screw section 1431 engaged with the screw nut 144 and an operating structure 1432 exposed outside the base body 110.

When the operating structure 1432 is operated, the screw 143 drives the screw nut 144 to move so as to swing the roller mount 120 relative to the base body 110.

In addition, in a fifth embodiment of the present invention, the present invention also provides an electrical apparatus. The electrical device of the present invention will be described with reference to fig. 11.

As shown in fig. 11, in the fifth embodiment of the present invention, the electrical device 300 includes the device body 310 and the base 100, and the base 100 may be the base described in any of the foregoing embodiments.

Further, the device body 310 and the base 100 may be fixedly connected as a whole, or may be detachably fixed together.

Alternatively, the electrical device 300 may be a refrigerator, freezer, or washing machine.

Based on the foregoing description, it can be understood by those skilled in the art that in the fifth embodiment of the present invention, the electrical device 300 can be moved not only by the support of the roller 130, but also the distance between the electrical device 300 and the bearing surface 200 can be adjusted by the driving means 140, so that the electrical device 300 can be prevented from being skewed.

Thus far, the technical solution of the present invention has been described in connection with the foregoing embodiments, but it will be readily understood by those skilled in the art that the scope of the present invention is not limited to only these specific embodiments. The technical solutions in the above embodiments can be split and combined by those skilled in the art without departing from the technical principles of the present invention, and equivalent changes or substitutions can be made to related technical features, so any changes, equivalent substitutions, improvements, etc. made within the technical principles and/or technical concepts of the present invention will fall within the protection scope of the present invention.
