As shown in FIG. 1 , the base body 110 is provided with a rotating shaft slot 111 and an installation cavity 112 . The rotating shaft slot 111 is used to fix the roller mounting base 131 , and the mounting cavity 112 is used to install the telescopic member 132 .

As shown in FIG. 1 , the lifting device 130 includes a roller mounting base 131 , a telescopic member 132 and an operating structure 133 . Among them, the roller mounting seat 131 is pivotally installed on the base body 110 . The roller 120 is rotatably mounted to the roller mounting base 131 . One end of the telescopic member 132 is connected to the roller mounting base 131 , and the other end of the telescopic member 132 is rotationally connected to the base body 110 . The telescopic member 132 is used to drive the roller mounting base 131 to swing relative to the base body 110 so that the roller 120 moves in a direction closer to or away from the base body 110, thereby adjusting the base body 110 and the bearing surface 200 (as shown in Figures 6 and 7 shown). The operating structure 133 is provided at the other end of the telescopic member 132 and is fixedly connected or made integrally with the telescopic member 132. The operating structure 133 is used to control the telescopic member 132 so that the telescopic member 132 drives the roller mounting base 131 to swing, thereby changing the The distance between the base body 110 and the roller 120.

As shown in FIGS. 4 to 7 , the rotating shaft 1311 of the roller mounting base 131 is installed in the rotating shaft slot 111 , and the rotating shaft 1311 is substantially parallel to the horizontal plane, so that the roller mounting base 131 can swing up and down around the rotating shaft.

Continuing to refer to FIGS. 4 to 7 , the telescopic member 132 includes a first telescopic member 1321 and a second telescopic member 1322 that are 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 move relatively to drive the roller mounting base 131 to swing relative to the base body 110 .

As shown in FIG. 5 , the first telescopic member 1321 includes a threaded hole 13211 , and the second telescopic member 1322 includes a threaded post 13221 . The threaded hole 13211 matches the threaded post 13221.

As shown in FIGS. 4 and 5 , the operating structure 133 is a column exposed on the front side of the base body 110 . As shown in Figure 5, the operating structure 133 is a hexagonal cylinder. In addition, those skilled in the art can also set the operating structure 133 to any other feasible structure with a non-circular cross-section as needed, such as a triangular prism, an elliptical prism, a quadrilateral prism, etc. Preferably, the first telescopic member 1321 and the operating structure 133 have threaded holes 13211 of bolts. In other words, the first telescopic member 1321 and the operating structure 133 are each a part of the bolt.

In addition, those skilled in the art can also configure the operating structure 133 as a sinking groove exposed on the front side of the base body 110 as needed, and the cross-section of the sinking groove is non-circular, such as a hexagonal sinking groove or a triangular sinking groove. , elliptical sinking trough, rectangular sinking trough, etc.

Continuing to refer to FIG. 5 , the second telescopic member 1322 is L-shaped as a whole. For convenience of explanation, the section with the threaded column 13221 on the second telescopic member 1322 is here referred to as the threaded section, and the second telescopic member 1322 without the threaded column 13221 is referred to as a threaded section. A section of is recorded as a connecting section. The second telescopic member 1322 is pivotally connected to the roller mounting base 131 through the connecting section.

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

In addition, in other embodiments of the present invention, those skilled in the art may also provide threaded posts on the first telescopic member 1321 and threaded holes matching the threaded posts on the second telescopic member 1322 as needed.

The usage method and working principle of the telescopic member 132 will be described in detail below with reference to Figures 6 and 7 .

When a certain roller 120 of the supporting base 100 is separated from the bearing surface 200 as shown in FIG. 6 and is suspended, the operator twists (specifically, a wrench can be used) the operating structure 133 to make the threaded column of the second telescopic member 1322 13221 is screwed into the threaded hole 13211 of the first telescopic member 1321, thereby shortening the lengths of the first telescopic member 1321 and the second telescopic member 1322, thereby causing the roller mounting base 131 shown in Figure 6 to rotate counterclockwise. The rotating roller mounting base 131 will cause the roller 120 to gradually approach the bearing surface 200 until it contacts the bearing surface 200 . As the operator continues to twist the operating structure 133, the roller mounting base 131 will gradually lift up its corresponding portion of the support base 100.

When a certain roller 120 of the support base 100 corresponds to a higher portion of the support base 100 , the operator reversely twists the operating structure 133 to cause the threaded column 13221 of the second telescopic member 1322 to unscrew the thread of the first telescopic member 1321 hole 13211, thereby lengthening the lengths of the first telescopic member 1321 and the second telescopic member 1322, thereby allowing the roller mounting base 131 shown in FIG. 6 to rotate clockwise. During this process, due to the gravity of the support base 100, the roller 120 will always be in contact with the bearing surface 200. When the pressure between the roller 120 and the bearing surface 200 is zero, the roller 120 can be separated from the bearing surface 200 as the operating structure 133 is continued to be twisted.

It can be seen that the roller mounting seat 131 is mainly installed through the tension of the telescopic member 132 and the support base 100 Gravity forces it to swing.

Furthermore, although not shown in the figure, in order to facilitate the relative movement between the first telescopic member 1321 and the second telescopic member 1322, those skilled in the art may also fill the threaded hole 13211 with grease as needed. When the roller 120 is in contact with the load-bearing surface 200, the threaded hole 13211 is tilted downward, so that the grease in the threaded hole 13211 flows to the threaded column 13221 under the action of its own gravity, so that the threaded column 13221 and the threaded hole 13211 are Lubricate the threads between them. Those skilled in the art can understand that since grease has viscosity, during the relative movement of the first telescopic member 1321 and the second telescopic member 1322, the threads meshing with each other will adhere to the grease.

Further, as can be seen from Figures 6 and 7, in the process of the roller mounting seat 131 and the roller 120 lifting the base body 110, the torque between the roller 120 and the roller mounting seat 131 gradually becomes smaller, which makes the support The base 100 can also enable the operator to easily twist the operating structure 133 when the objects on the base 100 (eg, refrigerator, washing machine) are heavy. In particular, the gradually decreasing torque can offset the acceleration of the object on the support base 100 when it rises.

Among them, the torque between the roller 120 and the roller mounting base 131 refers to "the force of the support base 100 and the objects on it acting on the rotating axis of the roller 120" and "the horizontal direction between the rotating axis 1311 and the rotating axis of the roller 120. product of the distance on.

At the same time, the threads engaged between the first telescopic member 1321 and the second telescopic member 1322 can act as a lever, allowing the operator to twist the operating structure 133 with only a small amount of effort, thereby lifting the base body 110 . Therefore, the support base 100 of the present invention achieves secondary labor saving and improves the user experience.

Referring back to FIGS. 1 to 3 , the support base 100 includes two legs 140 , which are disposed on the front side of the support base 100 and correspond to a roller mounting base 131 respectively. In addition, those skilled in the art can also set the legs 140 to any other feasible number as needed. For example, one, three, four, etc.

In the first embodiment of the present invention, when the support base 100 needs to be moved, the legs 140 are twisted forward to separate the legs 140 from the bearing surface 200 so that the rollers 120 close to the legs 140 are in contact with the bearing surface 200 . When the support base 100 does not need to move, twist the legs 140 in the opposite direction to make the legs 140 contact the bearing surface 200 and lift the base body 110 so that the rollers 120 close to the legs 140 are separated from the bearing surface 200 .

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

When assembling the support base 100, first install the roller mounting base 131 and the roller 120 together, and then install the roller mounting base 131 from the bottom of the base body 110 so that the roller mounting base 131 is embedded in the opening and faces downward. in the rotating shaft slot 111. Then, insert the second telescopic member 1322 from the installation cavity 112 onto the roller mounting base 131, and then pass the first telescopic member 1321 through the hole provided on the front side of the base body 110, and make the first telescopic member 1321 and the second telescopic member 1322 pass through the hole provided on the front side of the base body 110. The telescoping members 1322 are threaded together. Finally, the legs 140 are screwed into the threaded holes (not shown in the figure) on the base body 110 .

It should be noted that the aforementioned assembly sequence of the support base 100 is not fixed. Those skilled in the art can adjust the assembly sequence of the components of the support base 100 according to actual conditions.

Based on the foregoing description, those skilled in the art can understand that in the first embodiment of the present invention, the roller mounting base 131 is driven to swing through the telescopic member 132 so that the corresponding roller 120 can approach or move away from the base body 110, thereby Achieved 120 degrees of height adjustment for each roller. Therefore, the support base 100 of the present invention can not only move through the rollers 120, but also adjust the distance between the base body 110 and the bearing surface 200 through the telescopic member 132, thereby preventing the support base 100 from being tilted.

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

Furthermore, by arranging the operating structures 133 of all the telescopic members 132 on the front side of the support base 100, it is convenient for the operator to adjust the telescopic members 132 and the user's experience is optimized.

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

As shown in FIG. 8 , compared with the first embodiment, the support base 100 in the second embodiment of the present invention further includes a spring 150 set outside the first telescopic member 1321 . Specifically, in order to facilitate the operator to twist the operating structure 133 and to facilitate installation, the first telescopic member 1321 can slide relative to the base body 110 along its axial direction, and the operating structure 133 connects with the support through its end surface close to the first telescopic member 1321 The seat body 110 is in contact. The second telescopic member 1322 is provided with a stop structure 13222. One end of the spring 150 is in contact with the stop structure 13222, and the other end of the spring 150 is in contact with the base body 110. The spring 150 is used to provide a force for the roller 120 to move away from the base body 110.

Those skilled in the art can understand that if the support base 100 and the objects to be carried thereon do not exert a force on the roller 120 to press the bearing surface 200, the roller 120 will be separated from the bearing surface 200 under the action of the spring 150. Therefore, under the action of the spring 150, the operator can directly observe whether the roller 120 is detached from the load-bearing surface 200, and when the roller 120 is detached from the load-bearing surface 200, the operator can adjust the lifting device 130 so that the roller 120 is in contact with the load-bearing surface 200. .

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

As shown in FIG. 9 , compared with the first and second embodiments, the support base 100 in 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 from 132 becomes loose due to vibration, causing the roller mounting base 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 provided on the 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 fitted together with the operating structure 133 in the form of a hexagonal column shown in FIGS. 5 and 6 through the hexagonal hole structure shown in FIG. 9 .

Continuing to refer to FIG. 9 , corresponding to the locking cap 160 , the base body 110 is provided with an anti-skid fitting structure 113 , and the anti-skid fitting structure 113 matches the anti-skid structure 162 . Optionally, the anti-skid structure 162 and the anti-skid matching structure 113 are both anti-skid patterns. The portion of the base body 110 corresponding to the locking cap 160 is configured to be attracted by the magnet 161 . For example, an iron piece is provided at a position corresponding to the base body 110 and the locking cap 160 .

In the assembled state, the locking cap 160 and the operating structure 133 are detachably installed together, and the locking cap 160 is adsorbed to the base body 110 through the magnet 161, thereby matching the anti-skid structure 162 with the anti-skid matching structure 113. together to prevent the first telescopic member 1321 from loosening.

When it is necessary to adjust the telescopic member 132, the operator only needs to pull out the locking cap 160 from the operating structure 133.

Based on the foregoing description, those skilled in the art can understand that in the third embodiment of the present invention, the support base 100 can lock the telescopic member 132 through the locking cap 160 to prevent the telescopic member 132 from causing the roller mounting seat 131 to collapse. Abnormal swing ensures the stability of the support base 100 during long-term use.
