The supporting plate 2 is provided with a heat dissipation port 23, so that the damp-proof heat dissipation effect of the equipment 7 can be improved.

The working principle of the embodiment is as follows: when the supporting plate 2 is moved to a specified position, the groove-changing force application handle 63 rotates, the groove-changing swing rod 61 swings, the transmission toothed belt 41 drives the toothed belt wheel 4 to rotate, the lifting barrel 5 is prevented from rotating, the top groove bulge 42 gradually rotates from the ground clearance groove 53 to the adjacent ground-attaching shallow groove 54, the lifting barrel 5 is driven to descend in the process of overcoming the spring force of the ground clearance force application spring 56, when the top groove bulge 42 reaches the ground-attaching shallow groove 54, the ground-attaching rubber block 51 is attached to the ground, the top groove bulge 42 is kept in the ground-attaching shallow groove 54 to form a lock under the action of the weight of the equipment 7 and the reaction force of the ground-attaching rubber block 51, of course, the top groove bulge 42 passes through the high point at the near edge of the notch of the ground clearance groove 53 and the adjacent ground-attaching shallow groove 54 in the groove-changing process, so that the top groove bulge 42 can pass through smoothly, in this embodiment, the depth of the shallow groove 54 and the amount of compression deformation of the ground rubber block 51 during final ground adhesion should be smaller than the maximum allowable compression amount of the ground rubber block 51, so that the groove replacement process of the top groove protrusion 42 is equivalent to that the ground rubber block 51 is pressed hard and then rebounds slightly, and the ground rubber block 51 forms the final ground adhesion; through the operation, the ground-contacting rubber block 51 finally provides a larger friction force by means of the elastic acting force of the compression deformation of the ground-contacting rubber block, two-point fixation can be formed between the supporting plate 2 and the ground 1, and the universal wheels 21 are effectively prevented from being disturbed, so that the supporting plate 2 is kept stable, and the equipment 7 is placed stably; when the pallet 2 needs to be moved, the groove-changing force-applying handle 63 is rotated in the opposite direction, the top groove protrusion 42 gradually returns to the original ground-contacting shallow groove 53 from the ground-contacting shallow groove 54, this process is also equivalent to that the ground-contacting rubber block 51 is lifted up after being pressed down, and as long as the top groove protrusion 42 passes through the high points near the notch of the ground-contacting deep groove 53 and the ground-contacting shallow groove 54, the lifting cylinder 5 can automatically recover and rise due to the spring force of the ground-contacting force-applying spring 56, the ground-contacting rubber block 51 finally leaves the ground, the two-point fixation of the pallet 2 is released, and the four universal wheels 21 can play a role of walking again.

When the lifting guide column 3 needs to be removed, the ground-contacting adjusting cover 52 and the ground-contacting rubber block 51 thereon are firstly screwed off, then the fixing screws or bolts of the lifting guide column 31 are removed from the lower port of the lifting cylinder 5, and then the lifting guide column 31, the ground-contacting force application spring 56, the lifting cylinder 5 and the toothed pulley 4 can be sequentially removed from the supporting upright rod 3.

The device 7 can be stably placed and conveniently moved, the two states can be switched by simply pulling the groove-changing force application handle 63, the structure is compact, the operation is simple, and the device can be used for a television station room and can be popularized and applied to other occasions where more cabinet-type electronic devices 7 exist.

The basic principles, main features and advantages of the present invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
