As shown in fig. 1 to 3, in the first embodiment of the present invention, the movable support base 100 includes a base body 110, a roller 120, a lifting device 130, and an optional leg 140. The base body 110 is used for carrying and supporting an object to be carried. The roller 120 is mounted to the lifting device 130, the roller 120 being adapted for rolling contact with a bearing surface 200 (shown in fig. 6 and 7). The lifting device 130 is mounted on the base body 110, and the lifting device 130 is at least used for driving the base body 110 to move away from the roller 120 so as to increase the distance between the base body 110 and the bearing surface 200. The legs 140 are threadedly coupled to the base body 110. The legs 140 can move away from the base body 110 when twisted and can abut against the bearing surface 200 (shown in fig. 6 and 7) to jack up the base body 110, thereby disengaging the rollers 120 adjacent to the legs 140 from the bearing surface 200 (shown in fig. 6 and 7).

With reference to fig. 1 to 3, the four corners of the supporting base 100 are respectively provided with a lifting device 130, and each lifting device 130 is respectively corresponding to one roller 120. In addition, the skilled person can also adjust the installation position and number of the lifting devices 130 on the supporting base 100 and the number of the rollers 120 corresponding to each lifting device 130 as required. For example, three elevating devices 130 are provided for the support base 100, and the three elevating devices 130 are disposed right in front, left behind, and right behind the support base 100, respectively. Further, those skilled in the art can adjust the shape of the supporting base 100 according to the distribution of the lifting devices 130. Illustratively, if all the lifting devices 130 are distributed in a triangle, the shape of the support base 100 is set to be triangular. If all the elevating means 130 are distributed in a quadrangle, the shape of the support base 100 is set to a quadrangle (quadrangle). If all the elevating means 130 are distributed in a pentagon shape, the shape of the support base 100 is set to be a pentagon shape.

As shown in fig. 1, the base body 110 is provided with a rotating shaft engaging groove 111 and a mounting cavity 112. The shaft engaging groove 111 is used for fixing the roller mounting seat 131, and the mounting cavity 112 is used for mounting the telescopic member 132.

As shown in fig. 1, the lifting device 130 includes a roller mount 131, a telescopic member 132, and an operating structure 133. Wherein the roller mount 131 is pivotally mounted to the base body 110. The roller 120 is rotatably mounted to the roller mount 131. One end of the telescopic member 132 is connected to the roller mounting seat 131, and the other end of the telescopic member 132 is rotatably connected to the base body 110. The telescopic member 132 is used for driving the roller mounting seat 131 to swing relative to the base body 110, so as to move the roller 120 towards or away from the base body 110, thereby adjusting the distance between the base body 110 and the bearing surface 200 (shown in fig. 6 and 7). An operating structure 133 is disposed at the other end of the telescopic member 132 and fixedly connected or integrally formed with the telescopic member 132, and the operating structure 133 is used for controlling the telescopic member 132 to extend and retract so that the telescopic member 132 drives the roller mounting seat 131 to swing, thereby changing the distance between the base body 110 and the roller 120.

As shown in fig. 4 to 7, the rotation shaft 1311 of the roller mount 131 is mounted in the rotation shaft slot 111, and the rotation shaft 1311 is substantially parallel to a horizontal plane, so that the roller mount 131 can swing up and down around the rotation shaft.

With continued reference to fig. 4-7, telescoping member 132 includes first telescoping member 1321 and second telescoping member 1322 drivingly connected together. The first telescopic member 1321 is connected to the base body 110, and the second telescopic member 1322 is connected to the roller mounting seat 131. The first telescopic member 1321 and the second telescopic member 1322 are configured to be relatively movable to drive the roller mounting seat 131 to swing with respect to the base body 110.

As shown in FIG. 5, first telescoping member 1321 includes a threaded bore 13211 and second telescoping member 1322 includes a threaded post 13221. The threaded bore 13211 mates with the threaded post 13221.

As shown in fig. 4 and 5, the operation structure 133 is a cylinder exposed at the front side of the base body 110. As shown in fig. 5, the manipulation structure 133 is a hexagonal cylinder. Furthermore, the operating structure 133 can be configured to have any other feasible structure with a non-circular cross section, such as a triangular column, an elliptic column, a quadrangular column, etc., as required by those skilled in the art. Preferably, the first telescopic member 1321 and the operating structure 133 are bolts having threaded holes 13211. In other words, the first telescopic member 1321 and the operating structure 133 are each part of a bolt.

In addition, the skilled person can also set the operation structure 133 as a sinking groove exposed at the front side of the base body 110, and the cross section of the sinking groove is non-circular, such as a hexagonal sinking groove, a triangular sinking groove, an elliptical sinking groove, a rectangular sinking groove, etc., as required.

With continued reference to fig. 5, second telescoping member 1322 is generally L-shaped, and for ease of illustration, a section of second telescoping member 1322 having threaded post 13221 is referred to herein as a threaded segment, and a section of second telescoping member 1322 not having threaded post 13221 is referred to herein as a connecting segment. Second telescoping member 1322 is pivotally coupled to roller mount 131 via the connecting segment.

As shown in fig. 6 and 7, when the operating mechanism 133 is operated, the first telescopic member 1321 is driven to rotate, so that the threaded column 13221 moves in a direction of extending into or out of the threaded hole 13211 to change the length of the first telescopic member 1321 and the second telescopic member 1322, thereby driving the roller mounting seat 131 to swing relative to the base body 110.

In addition, in other embodiments of the present invention, a person skilled in the art may also set a threaded post on the first telescopic member 1321 and set a threaded hole matching the threaded post on the second telescopic member 1322, as required.

The method of use and the principle of operation of the telescopic member 132 will be described in detail below with reference to fig. 6 and 7.

When one of the rollers 120 of the supporting base 100 is separated from the supporting surface 200 as shown in fig. 6 and is suspended, the operator screws (specifically, using a wrench) the operation structure 133 to screw the threaded post 13221 of the second telescopic member 1322 into the threaded hole 13211 of the first telescopic member 1321, so that the lengths of the first telescopic member 1321 and the second telescopic member 1322 are shortened, and the roller mounting seat 131 shown in fig. 6 is rotated counterclockwise. The rotating roller mount 131 brings the roller 120 closer to the bearing surface 200 until it abuts the bearing surface 200. As the operator continues to twist the operating structure 133, the roller mount 131 gradually lifts the portion of the corresponding support base 100.

When one of the rollers 120 of the support base 100 is higher than the corresponding portion of the support base 100, the operator reversely twists the operating structure 133 to rotate the threaded post 13221 of the second telescopic member 1322 out of the threaded hole 13211 of the first telescopic member 1321, so that the lengths of the first telescopic member 1321 and the second telescopic member 1322 are increased, and the roller mounting seat 131 shown in fig. 6 is further rotated clockwise. In the process, the roller 120 is always abutted against the bearing surface 200 due to the gravity of the support base 100. When the pressure between the roller 120 and the bearing surface 200 is zero, the roller 120 may be separated from the bearing surface 200 as the operation structure 133 is continuously screwed.

It can be seen that the roller mounts 131 are forced to swing primarily by the tension of the telescoping members 132 and the weight of the support base 100.

Further, although not shown in the drawings, in order to facilitate the relative movement between the first telescopic member 1321 and the second telescopic member 1322, a person skilled in the art may fill the threaded hole 13211 with grease as necessary. And when the roller 120 abuts the bearing surface 200, the threaded bore 13211 is inclined downwardly so that grease within the threaded bore 13211 flows under its own weight to the threaded stub 13221, thereby lubricating the threads between the threaded stub 13221 and the threaded bore 13211. As will be appreciated by those skilled in the art, due to the viscosity of the grease, the threads that engage each other adhere to the grease during relative movement of first telescoping member 1321 and second telescoping member 1322.

Further, as can be seen from fig. 6 and 7, during the process that the roller mounting seat 131 and the roller 120 jack up the base body 110, the torque between the roller 120 and the roller mounting seat 131 gradually becomes smaller, which enables the operator to easily screw the operation structure 133 even when the support base 100 has heavy objects thereon (e.g., refrigerator, washing machine). In particular, the gradually decreasing torque can counteract the acceleration of the object on the support base 100 as it rises.

Here, the torque between the roller 120 and the roller mount 131 is a product of "a force acting on the rotation shaft of the roller 120 by the support base 100 and an object thereon" and "a distance in a horizontal direction between the rotation shaft 1311 and the rotation shaft of the roller 120".

At the same time, the threads engaged between first telescoping member 1321 and second telescoping member 1322 act as a lever, allowing the operator to twist operating structure 133 with only a small amount of force to jack base body 110. Therefore, the utility model discloses a support base 100 has realized that the secondary is laborsaving, has promoted user's use and has experienced.

Returning to continue to refer to fig. 1-3, the support base 100 includes two legs 140, the two legs 140 being disposed on the front side of the support base 100 and respectively corresponding to one of the roller mounts 131. Further, one skilled in the art can also set the legs 140 to any other feasible number as desired. Such as one, three, four, etc.

In the first embodiment of the present invention, when the supporting base 100 needs to be moved, the supporting legs 140 are twisted in the forward direction to separate the supporting legs 140 from the bearing surface 200, so that the rollers 120 adjacent to the supporting legs 140 abut against the bearing surface 200. When the supporting base 100 does not need to be moved, the legs 140 are reversely twisted to make the legs 140 abut against the bearing surface 200, so as to jack up the base body 110, thereby making the rollers 120 adjacent to the legs 140 separate from the bearing surface 200.

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

When the support base 100 is assembled, the roller mounting seat 131 and the roller 120 are mounted together, and then the roller mounting seat 131 is mounted from the lower side of the base body 110, so that the roller mounting seat 131 is inserted into the shaft slot 111 with the opening facing downward. Second telescoping member 1322 is then inserted from mounting cavity 112 onto roller mount 131, first telescoping member 1321 is then passed through an aperture provided on the front side of base body 110, and first telescoping member 1321 and second telescoping member 1322 are threaded together. Finally, the legs 140 are screwed into threaded holes (not shown) in the base body 110.

It should be noted that the aforementioned assembly sequence of the supporting base 100 is not fixed, and those skilled in the art can adjust the assembly sequence of the components of the supporting base 100 according to actual situations.

Based on the foregoing description, it can be understood by those skilled in the art that, in the first embodiment of the present invention, the roller mounting seat 131 is driven to swing by the telescopic member 132, so that the corresponding roller 120 can be close to or far from the base body 110, thereby realizing the adjustment of the height of each roller 120. Therefore, the support base 100 of the present invention can not only move through the roller 120, but also adjust the distance between the base body 110 and the bearing surface 200 through the telescopic member 132, so that the support base 100 can be prevented from being inclined.

Further, in the first embodiment of the present invention, the support legs 140 can prevent the support base 100 from moving, and fix the support base 100.

Still further, through setting up all operation structure 133 of telescopic member 132 in the front side that supports base 100, made things convenient for operating personnel to the regulation of telescopic member 132, optimized user's use and experienced.

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

As shown in fig. 8, compared to the first embodiment, the supporting base 100 of the second embodiment of the present invention further includes a spring 150 sleeved outside the first telescopic member 1321. Specifically, for the convenience of the operator to screw the operating structure 133 and for the convenience of installation, the first telescopic member 1321 is slidable in its axial direction with respect to the base body 110, the operating structure 133 abutting with its end face close to the first telescopic member 1321 the seat body 110. Second telescoping member 1322 is provided with a stop structure 13222. One end of the spring 150 abuts the stop structure 13222 and the other end of the spring 150 abuts the base body 110, the spring 150 being configured to provide a force to the roller 120 away from the base body 110.

It can be understood by those skilled in the art that if the support base 100 and the object to be carried thereon do not apply a force to the roller 120 to press against the bearing surface 200, the roller 120 is separated from the bearing surface 200 by the spring 150. Therefore, under the action of the spring 150, the operator can directly observe whether the roller 120 is disengaged from the bearing surface 200, and adjust the lifting device 130 to contact the roller 120 with the bearing surface 200 when the roller 120 is disengaged from the bearing surface 200.

A support base 100 according to a third embodiment of the present invention will be described with reference to fig. 9.

As shown in fig. 9, compared with the first and second embodiments, the support base 100 of the third embodiment of the present invention further includes a locking cap 160. The locking cap 160 is used to lock the telescopic member 132 to prevent the telescopic member 132 from being loosened by vibration, thereby causing the roller mount 131 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 operating structure 133 of the telescopic member 132. For example, the locking cap 160 is engaged with the operation structure 133 in the form of a hexagonal column shown in fig. 5 and 6 through a hexagonal hole structure shown in fig. 9.

With reference to fig. 9, corresponding to the locking cap 160, the base body 110 is provided with an anti-slip structure 113, and the anti-slip structure 113 is matched with the anti-slip structure 162. Optionally, the slip resistant structure 162 and the slip resistant mating structure 113 are both non-slip threads. A 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 disposed at a position of the base body 110 corresponding to the locking cap 160.

In an assembled state, the locking cap 160 is detachably mounted with the operating structure 133, the locking cap 160 is adsorbed to the base body 110 by the magnet 161, and thus the slip prevention structure 162 is matched with the slip prevention engagement structure 113 to prevent the first telescopic member 1321 from being loosened.

When the telescopic member 132 needs to be adjusted, the operator only needs to pull the locking cap 160 off the operating structure 133.

Based on the foregoing description, it can be understood by those skilled in the art that, in the third embodiment of the present invention, the support base 100 can lock the telescopic member 132 through the locking cap 160, and prevent the telescopic member 132 from making the roller mounting seat 131 abnormally swing, thereby ensuring the stability of the support base 100 in long-term use.

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

As shown in fig. 10, compared with the first, second and third embodiments, in the fourth embodiment of the present invention, the structure of the base body 110 is changed accordingly. Specifically, the base body 110 replaces the mounting cavity 112 with an avoidance structure 114.

During the assembly of the support base 100, the roller mounts 131 are similarly inserted into the shaft slots 111 from the bottom side of the base body 110. Then, the operator inserts the first telescopic member 1321 into the roller mount 131 from the avoidance structure 114.

Furthermore, in the fifth embodiment of the present invention, the present invention further provides an electrical apparatus. The electrical equipment of the present invention will be described with reference to fig. 11.
