Abstract

The invention discloses a lifting driving device with a one-way brake locking function, which is characterized in that a transmission shaft (1) of the lifting driving device is connected with a spirallifter in a lifting upright post assembly (8), and a locking structure is arranged on the transmission shaft; the locking structure comprises a brake base shell (5) installed on the transmission shaft in a clearance fit mode, a brake base (7) installed on the transmission shaft in an interference fit mode and a brake spring (6) installed on the brake base in an interference fit mode, an installation groove (51) is formed in the brake base shell, the brake base is installed in the installation groove, and the brake spring is a spiral spring. The rotation direction of the spiral spring is consistent with the rotation direction of the transmission shaft and the brake base when the lifting stand column assembly extends, the spiral spring is provided with a first end (61) and a second end (62), the first end is limited by the installation groove, and the second end is in a free state. Locking of the lifting driving device during contraction can be realized, so that the lifting driving device does not slide down during load bearing.

Description

technical field [0001] The invention relates to an electric lifting table, in particular to a lifting driving device with a one-way braking and locking function. Background technique [0002] The electric lift table can change the height of the table body to meet people's individual needs, so that people can work and study in the most comfortable posture. [0003] As shown in Chinese patent CN209732949U, electric lift tables on the market generally use a motor-driven screw jack to realize the lifting function. In order to increase the lifting speed of the electric lifting table, the industry usually shortens the screw lead of the screw lift to achieve this, which leads to the inability of the electric lifting table to stop under a certain load, that is, the lifting structure of the electric lifting table after bearing the load. In the process of driving the heavy-duty desktop down, the desktop cannot be locked, and the desktop slides down. Contents of the invention [00...
