Abstract: A steel wire self-locking mechanism and a lifting device are provided. The steel wire self-locking mechanism includes a surrounding plate and a self-locking gear and a locking device arranged in the surrounding plate, and uses a friction force of a threaded sleeve to lock the lifting device. The lifting device includes a lifting assembly and a beam assembly. The steel wire self-locking mechanism is arranged in the beam assembly, and the locking of the lifting device is realized by the steel wire self-locking mechanism. The steel wire self-locking mechanism and the lifting device have good adaptability. Due to a smaller volume, the steel wire self-locking mechanism is applicable to lifting tables in various sizes.

Abstract: A synchronizing lifter and a lifting table are disclosed that can ensure components supported on the synchronizing lifter cannot be in an inclined state. This has advantages in that by releasing the locking of one of power output portions of a linear driver, a first flexible traction component, a second flexible traction component, a first bracket and a second bracket through a locking mechanism, the driver works and a flexible connection component connected to the output end of the driver can move. The power is transferred to a corresponding bracket that drives a power transfer component to move up or down. The power transfer component drives the other bracket to move up or down, and another bracket drives the other flexible traction component to move. One driver drives the two ends of a synchronizing mechanism to move up and down, so that the structure is simple and costs are kept low.

Abstract: A pressure-adjustable gas spring includes a first gas spring and a gas source for adjusting a pressure. One end of the gas source is connected with the first gas spring and another end is connected with an adjustment device for adjusting the volume of the gas source. The adjustment device includes a cavity for accommodating the gas source and a piston. One end of the piston opposite the gas source is connected with a driving subassembly. The driving subassembly includes a screw. One end of the screw is connected with the piston and another end extends out of the cavity. A nut is arranged on the end of the screw extending out of the cavity. A connection tube is arranged outside the nut in a sleeving manner. One end of the connection tube is connected with the cavity and a rotating block is mounted at an opening of another end.
