Description

Technical Field

[0001] The utility model belongs to the technical field of lifting tables, and in particular relates to a driving device for a lifting table. Background Art

[0002] The lifting table uses a driving device to drive the table legs to rise and fall; the existing driving device generally uses a motor as a power source, and the rotation of the motor output shaft drives the rotation of the screw rod in the table leg, thereby achieving lifting; in order to make the table more stable, the existing lifting table generally uses at least two columns, and the two columns are synchronously lifted and lowered by a motor.

[0003] However, the two columns are arranged vertically and there is only one motor, which means that the motor needs to be connected to the two columns through a conversion device. Therefore, on the lifting table frame, it is necessary to set a motor mounting position and a conversion device mounting position to install the motor and the conversion device respectively. Since the two are installed separately on the lifting table frame, the matching accuracy between the two is very high, and shaking and bumping are inevitable during handling and transportation, which makes it easy for the motor to produce abnormal noise due to changes in the matching accuracy between the motor and the conversion device during use of the lifting table.

[0004] Therefore, it is necessary to design a driving device for a lifting table to solve the above problems. Utility Model Content

[0007] Furthermore, the cavity is divided into a second installation cavity and a third installation cavity; wherein the bottoms of the second installation cavity and the third installation cavity are respectively provided with a first through hole and a second through hole connected to the first installation position; a driving circuit board is arranged in the second installation cavity, and the bevel gear is arranged in the third installation cavity; the driving shaft is suitable for extending into the third installation cavity through the second through hole, and the driving circuit board is connected to the motor through the first through hole.

[0008] Furthermore, a limiting groove is provided on the upper box body, and the limiting groove is located at the top of the third installation cavity; and the end of the driving shaft is suitable for extending into the limiting groove.

[0009] Furthermore, a worm is arranged on the driving shaft, and a side wall of the helical gear is provided with helical teeth matching the worm.

[0010] Furthermore, a rotating rod is arranged at the axis of the bevel gear, and both ends of the rotating rod pass through the third installation cavity.

[0011] Furthermore, both end surfaces of the rotating rod are respectively provided with hexagonal limiting grooves to form the output position.

[0012] Furthermore, a slot is provided on the side wall of the second installation cavity; the driving circuit board is inserted into the slot.

[0013] The beneficial effect of the utility model is that the driving device for the lifting table adopts bevel gears to convert the output direction of the driving shaft torque, so that it can generate output force in two directions, so that the two columns can be connected; at the same time, the bevel gears and the motor are both arranged on the upper box body and the lower box body, so that the two form a whole, thereby improving the matching accuracy between the two and preventing the matching accuracy from decreasing due to shaking during transportation or handling.
