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.
Claims18
A hand rotary releasing structure, comprising:
- a connecting seat, comprising multiple clutch troughs disposed spacedly on a peripheral surface thereof;
- a clutch seat, disposed on a side of the connecting seat, and comprising multiple engaging troughs arranged corresponding to the clutch troughs;
- a clutch, movably disposed between the connecting seat and the clutch seat, comprising a ring, multiple clutch keys and multiple protrusions, the clutch keys disposed on an inner surface of the ring corresponding to the clutch troughs, and the protrusions disposed spacedly on an outer surface of the ring;
- an adaptor sleeve, adapted to sheathe the clutch, comprising multiple spiral troughs, and the spiral troughs arranged corresponding to the protrusions;
- and
- a return spring, adapted to sheathe the connecting seat, and abutting against the clutch.
A linear actuator comprising:
- an actuating mechanism, comprising a motor and a lead screw driven by the motor;
- a telescopic structure, comprising a nut axially disposed around the lead screw and a telescopic tube penetrating the nut;
- and
- a hand rotary releasing structure, disposed on an outer end of the telescopic tube, and comprising:
- a connecting seat, comprising multiple clutch troughs disposed spacedly on a peripheral surface thereof;
- a clutch seat, disposed on a side of the connecting seat, and comprising multiple engaging troughs arranged corresponding to the clutch troughs;
- a clutch, movably disposed between the connecting seat and the clutch seat, comprising a ring, multiple clutch keys and multiple protrusions, the clutch keys disposed on an inner surface of the ring corresponding to the clutch troughs, and the protrusions disposed spacedly on an outer surface of the ring;
- an adaptor sleeve, adapted to sheathe the clutch, comprising multiple spiral troughs, and the spiral troughs arranged corresponding to the protrusions;
- and
- a return spring, adapted to sheathe the connecting seat, and abutting against the clutch.
