Problems solved by technology

But, the shortcoming that the lifting table leg of this structure has is: because in normal use, motor is in power-off state, that is, table is static, but, the weight of table board and related parts, adds that screw rod itself does not have self-locking ability, so that the table has a downward pressure on the table legs, causing the table legs to have a downward trend. Therefore, after a long period of use, the desktop will appear to drop unconsciously, which will affect the use.

Abstract

The invention discloses a rotation stopping structure of a hoistable table leg. The rotation stopping structure comprises a screw rod (1) for supporting the inner part of the hoistable table leg and a rectangular slide block (2) which is in sliding match in the hoistable table leg, and further comprises a unidirectional bearing (3), wherein the inner surface of the unidirectional bearing (3) is matched with the end part of the screw rod (1); and the outer surface of the unidirectional bearing (3) is matched with the rectangular slide block (2). With the adoption of the structure, the unidirectional bearing is arranged at the end part of the screw rod, and the screw rod only can smoothly rotate along the forward direction of the unidirectional bearing and cannot rotate in the opposite direction, so that a self-locking function is provided for backward rotation of the screw rod, and a tabletop does not automatically descend.

Description

technical field [0001] The invention relates to the technical field of lift tables, in particular to an anti-rotation structure for lift table legs. Background technique [0002] Lifting desks have gradually become popular in people's daily life, and are mostly used in various fields such as study, office and entertainment. It usually includes a table, a base and a lifting device, and the table is connected to the base through the lifting device. The power source of the lifting table is provided by an electric motor, and once the motor is powered on, it can drive the screw to push and pull the table legs to raise and lower. Usually the table legs of the lifting table have a telescopic structure, that is to say, the outside of the table leg is composed of two parts, which are respectively connected by the outer tube and the inner tube; the inside of the table leg is equipped with a screw, a slider, a limit Parts such as support blocks, wherein the upper end of the screw is ...
