A screw rod self-locking device includes a one-way bearing and a mounting seat, and an inner hole of the one-way bearing is sleeved at an end of a screw rod. A mounting hole for receiving the one-way bearing is disposed on the mounting seat, and the one-way bearing is rotatably fitted into the mounting hole along a circumferential direction. An adjusting mechanism for adjusting a circumferential locking force of the mounting hole for the one-way bearing is disposed on the mounting seat so as to adjust a size of a friction force between an outer wall of the one-way bearing and an inner wall of the mounting hole. A height-adjustable leg and a height-adjustable desk applying the same are further provided. In this way, a size of a self-locking friction force to be overcome during backward rotation of a screw rod can be self-defined, thereby guaranteeing consistency of product performances.

A frame for sit- stand-tables comprising a longitudinal member, two height-adjustable legs with at least two telescopic profiles, namely an outer and an inner profile, and with a driving mechanism, driven by a motor unit, comprising an electric motor and a gear. According to the invention the motor unit is arranged in the longitudinal member and connected to the driving mechanism in the height-adjustable legs. Thus, a frame with a simplified construction is achieved. The construction of the legs can be simplified and at the same time the dimensions can be reduced, as it is not necessary to take the building-in of a motor into the legs into consideration. As both legs are driven by a joint motor unit, the electric control can also be simplified as it will not have to drive the two legs synchronously.

Disclosed is a self-locking apparatus for a linear actuator, which relates to the field of linear actuation equipment. The self-locking apparatus includes a one-way bearing and a friction collar, wherein the one-way bearing includes an inner race and an outer race, the inner race being sleeved to the rotary screw of the linear actuator, the friction collar being connected to the outer race; wherein the self-locking apparatus further includes a friction member fitted with the friction collar, such that when the rotary screw rotates forwardly, the outer race does not rotate; and when the rotary screw rotates reversely, the outer race, the inner race, and the friction collar rotate synchronously, such that friction is produced by contacting between the friction collar and the friction member. Further disclosed is a linear actuator applying the self-locking apparatus.
