    Abstract: An electric linear actuator has a guide screw and a telescopic tube. A safety mechanism for the linear actuator includes a nut, a nut sheath, a sleeve, and a torsion spring. The nut connects the guide screw. The nut sheath is fixed on one side of the nut and is provided with a plurality of bumps. One end of the sleeve is put around the nut sheath and the other end thereof is connected to the telescopic tube. The sleeve is provided with a plurality of rabbets corresponding to the bumps. The torsion spring is disposed around the nut sheath and the sleeve. When the guide screw is rotated, the nut sheath is engaged with the sleeve by embedding the bumps into the rabbets. When the sleeve stops, the bumps and the rabbets depart from engagement to make the nut sheath and the nut freely rotate against the sleeve.

    Abstract: A linear actuator (1) includes an electrical driving mechanism (10), a lead screw (20), an outer tube (30), a telescopic tube (40) and an arm driven mechanism (50). The arm driven mechanism (50) comprises an arm (51), a driving nut (52), a telescopic sleeve (53), a first washer (54), a nut-tube (55) and a second washer (56). The arm (51) is provided with a handle (511) and a sleeve (512), and the sleeve (512) links with the lead screw (20). An outer peripheral of the telescopic sleeve (53) provided with a plural of screws for screwing with the telescopic tube (40). The nut-tube (55) links with the driving nut (52) for moving together. When the handle (511) rotates, the linear actuator (1) can be operated.

    Abstract: A linear actuator includes a sliding rod, a motor and a buffer assembly. The motor connects the sliding rod to drive the sliding rod. The buffer assembly is disposed at an end of the sliding rod and includes an elastic element and an outer sleeve. The elastic element is received in the outer sleeve. The sliding rod connects the outer sleeve. The outer sleeve is movable along an axial direction of the sliding rod. The elastic element separately pushes an inner wall of the outer sleeve and the sliding rod. The elastic element is pre-compressed along the axial direction of the sliding rod. The buffer assembly can absorb vibration and impact caused by the motor driving the sliding rod.

    Abstract: A linear actuator includes a housing, motors, actuator members, clutch members, a base, a clutch driver, and a pulling handle. The motors are disposed in the housing. The actuator members are respectively disposed in the housing and corresponding to a respective one of the motors. Each clutch member is connected between a respective one of the motors and a respective corresponding one of the actuator members. The base is disposed on an outer surface of the housing, a flange is disposed on an outer surface of the base, and a guiding slot is formed on the base. The clutch driver is in the base and connected to each of the clutch members. A cam contacting against the flange is formed on an end of the pulling handle, and a shaft is inserted through the end. The shaft is inserted through the guiding slot to connect the clutch driver.
