    Abstract: A linear actuator includes an actuating mechanism, a telescopic structure and a hand rotary releasing structure. The hand rotary releasing structure includes a connecting seat, a clutch seat, a clutch, an adaptor sleeve and a return spring. A peripheral surface of the connecting seat is disposed with multiple clutch troughs. The clutch seat includes multiple engaging troughs. The clutch is disposed between the connecting seat and the clutch seat. The adaptor sleeve is disposed around the clutch and includes multiple spiral troughs. The return spring is disposed around the connecting seat and abuts against the clutch to reduce the activating time and steps of release.

    Abstract: An industrial heavy load electric linear actuator includes a gearbox, an electric motor, a lead screw, an extension pipe and a load baring structure. The electric motor is connected to the gearbox. A portion of the lead screw is received inside the gearbox and driven by the electric motor, and another portion of the lead screw is extended out of the gearbox. The extension pipe is movably fastened to the lead screw. The load bearing structure includes a sleeve, a bearing, a fastening element, a fixation seat, and a rear supporting seat. The sleeve is mounted to the lead screw and holds the bearing jointly with the fastening element. The fixation seat and the rear supporting seat hold the bearing at outer perimeters of the sleeve and the fastening element.

    CPC classification number: A47B9/20 A47B13/02 A47B2200/0051 A47B2200/0056

    Abstract: A lightweight beam structure includes a first and a second frame. The first frame includes an upper plate, two inner side plates downward bent and extended from two sides of the upper plate, two outer side plates upward bent and extended from two inner side plates respectively and two fixing plates bent and extended from two outer side plates respectively. Each outer side plate is formed outside each inner side plate. A groove is formed between each inner side plate and each outer side plate. The second frame is connected with the first frame and includes a top plate and two intermediate plates downward bent and extended from two sides of the top plate. Each intermediate plate is received in each groove. The top plate is formed over the upper plate. Therefore, the stability is maintained and the weight is reduced so that the material costs may be decreased.
