The driving device includes a motor and a shaft coupling, the motor is arranged transversely at the bottom of the table top, and the shaft coupling is arranged longitudinally and fixedly connected with the output shaft of the motor.

The upper tube includes an upper outer tube and an inner tube arranged in the upper outer tube, the upper end of the upper outer tube is fixed on the bottom of the tabletop, the upper end of the inner tube is fixedly connected with the coupling, the inner tube An outer screw sliding block that can slide up and down is arranged in the tube.

The middle tube includes a middle outer tube and an outer screw, the lower end of the upper outer tube can be inserted into the middle outer tube in a slidable up and down manner, and the upper end of the outer screw is fixedly connected with the outer screw sliding block. The outer screw is provided with a central hole, and the inner screw nut is arranged at the bottom of the central hole.

The lower tube includes a lower outer tube and an inner screw, the lower end of the middle outer tube is inserted into the lower outer tube so that it can move up and down, the inner screw is threaded with the inner screw nut, and the lower outer tube The lower end of the tube and the lower end of the internal screw are fixed on the base.

The beneficial effects of the utility model are: the utility model has reasonable and ingenious design, high structural strength, stable and reliable quality, convenient and flexible use, and can meet the needs of long-term use. And the table legs are divided into three sections, which can be lifted and stretched in a relatively large range, so that the use range is wide and it is convenient for users of different heights to use.

Below in conjunction with accompanying drawing and embodiment, the utility model is further described.

detailed description

Embodiment: As shown in Figures 1 to 4, the utility model is a liftable table, which includes a desktop 1, a table leg 2, a driving device 3 and a base 4, and the table leg 2 and the driving device 3 are arranged on the The bottom of the desktop 1, the table leg 2 is connected with the driving device 3, the table leg 2 includes an upper tube 21, a middle tube 22 and a lower tube 23, and the upper tube 21 can be lifted and inserted in the middle Among the tubes 22 , the middle tube 22 is liftably inserted into the lower tube 23 , and the lower tube 23 is fixed on the base 4 .

The driving device 3 includes a motor 31 and a shaft coupling 32 , the motor 31 is arranged transversely at the bottom of the desktop 1 , and the shaft coupling 32 is arranged longitudinally and fixedly connected with the output shaft of the motor 31 .

The upper tube 21 includes an upper outer tube 211 and an inner tube 212 arranged in the upper outer tube 211, the upper end of the upper outer tube 211 is fixed on the bottom of the desktop 1, and the upper end of the inner tube 212 is connected to the coupling. The shaft device 32 is fixedly connected, and the inner tube 212 is provided with an outer screw sliding block 213 which can slide up and down.

The middle tube 22 includes a middle outer tube 221 and an outer screw 222. The lower end of the upper outer tube 211 is inserted into the middle outer tube 221 in a sliding manner up and down. The upper end of the outer screw 222 is connected to the outer screw 222. The sliding block 213 is fixedly connected, the outer screw rod 222 is provided with a central hole 223 , and an inner screw nut 224 is provided at the bottom of the central hole 223 .

The lower tube 23 includes a lower outer tube 231 and an inner screw 232, the lower end of the middle outer tube 221 is inserted into the lower outer tube 231 so as to move up and down, the inner screw 232 and the inner screw nut 224 Threaded connection, the lower end of the lower outer tube 231 and the lower end of the inner screw 232 are fixed on the base 4 .
