[0022] Embodiment

[0023] For an electric lifting table, please refer to Figures 1-4 , the electric lifting table includes two groups of bases 3. A drive motor 6 is installed at the bottom of the base 3, and a leg sleeve 1 is arranged at the bottom of the drive motor 6;

[0024] Specifically, the bottom end output shaft of the drive motor 6 is connected with a lead screw, and the lead screw is in threaded fit inside the leg sleeve 1. The drive motor 6 and the leg sleeve 1 form a common leg assembly with a lifting function in the market. A control switch can also be installed on the base 3, and the control switch is electrically or wirelessly communicatively connected to the drive motor 6. The above are all prior arts, so this application will not be described in detail;

[0025] Fixed seats 4 are fixedly connected to the tops of both bases 3. A number of groups of assembled table blocks 5 are arranged between the two fixed seats 4. A second card slot 52 is opened on one side of the assembled table block 5, and a second card block 51 that is matched with the second card slot 52 is fixedly connected to the other side of the assembled table block 5. Fixed slots 50 are opened at both ends of the assembled table block 5, and two groups of movable rods 34 are symmetrically arranged inside the base 3;

[0026] Specifically, one end of the movable rod 34 can be inserted into the fixed slot 50, and a moving assembly for driving the two groups of movable rods 34 to move towards or away from the fixed slot 50 is also arranged inside the base 3. The second card block 51 on one side of an assembled table block 5 can be inserted into the second card slot 52 on one side of another assembled table block 5, so that multiple assembled table blocks 5 can be quickly spliced with each other.

[0027] In an optional embodiment: the moving assembly includes a threaded rod 31 rotatably connected to the inner wall of the fixed seat 4, two nut blocks 32 are symmetrically threaded on the two threaded rods 31, and one end of each movable rod 34 is fixedly connected to a nut block 32.

[0028] In an alternative embodiment: The base 3 is arranged in a U shape, and the movable rod 34 is arranged in an L shape. Both inner side walls at the two ends of the base 3 near one side of the assembled table block 5 are provided with notches 300, and one end of the movable rod 34 slides through the notches 300;

[0029] Specifically, by arranging the base 3 in a U shape, the base 3 can better contact the assembled table block 5, so that they are stably connected together. When the assembled table block 5 contacts the inner side wall of the base 3, the notch 300 is coaxially arranged with the fixing groove 50, then the movable rod 34 can enter the fixing groove 50 after passing through the notch 300 to fix between the base 3 and the assembled table block 5.

[0030] In an alternative embodiment: A first card slot 30 matching with the second card block 51 is provided in the middle of one side of one base 3 near the assembled table block 5, and a first card block 33 matching with the second card slot 52 is fixedly connected to the middle of one side of the other base 3 near the assembled table block 5;

[0031] Specifically, the second card block 51 on one of the assembled table blocks 5 can be inserted into the first card slot 30 on one side of one base 3, and the first card block 33 on one side of the other base 3 can be inserted into the second card slot 52 on one side of the other assembled table block 5, so that the assembled table block 5 is stably connected between the two bases 3.

[0032] In an alternative embodiment: One end of the threaded rod 31 penetrates to the outside of the base 3 and is fixedly connected with a turning handle. By turning the turning handle, the rotation of the screw rod can be facilitated. Further, two groups of threads with opposite directions are arranged on the threaded rod 31, and the threads match the inner side wall of the nut block 32. Then when the threaded rod 31 is rotated, the two nut blocks 32 can move towards or away from each other.

[0033] In an alternative embodiment: A supporting bottom block 2 is fixedly installed at the bottom of the leg sleeve 1, and rubber gaskets 21 are fixedly connected to both sides of the bottom of the supporting bottom block 2. The rubber gaskets 21 play a role in anti-sliding, and through the supporting bottom block 2 and the rubber gaskets 21, the lifting table of the present application is more stably placed on the tabletop.

[0034] Specifically, when changing the width of the tabletop, according to the accommodation space for placing the electric lifting table or according to the width usage requirement of the tabletop, select an appropriate number of assembled table blocks 5, connect the assembled table blocks 5 together, and a plurality of assembled table blocks 5 form an integral tabletop, and make the assembled table blocks 5 at both ends of the tabletop contact the base 3. Then turn the turning handle so that the movable rod 34 fixes the base 3 and the two assembled table blocks 5, and the tabletop is stably fixed to the tabletop, so that the width of the tabletop of the electric lifting table can be flexibly changed to meet the usage requirements;

[0035] When transporting the electric lifting table, just rotate the turning handle in the reverse direction to disengage the movable rod 34 from the assembled table block 5, and then pull out each assembled table block 5, so that the electric lifting table can be quickly disassembled, facilitating the disassembly and assembly of the electric lifting table. Moreover, after disassembly and assembly, the space is saved, which is convenient for the transportation of the overall electric lifting table.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
