Problems solved by technology

[0002] At present, hand-rotary linear actuators are widely used in various fields. The existing hand-rotary linear actuators guide the inner tube axially through the support seat and also radially position the inner tube. When the inner tube of the linear actuator pushes the object, the inner tube will be subjected to radial force. When the radial force on the inner tube is too large, the inner tube will press the support seat under the action of the radial force. When the inner tube needs to be rotated by hand, because the friction between the inner tube and the support seat is too large, the inner tube cannot be rotated to retract into the outer tube, and the user experience is poor

Embodiment 1

[0029] A hand-rotated linear actuator such as figure 1 with figure 2 As shown, it includes a casing 1, an outer tube 2 fixed on the casing 1, and an inner tube 3 sleeved in the outer tube 2. The inner tube 3 expands and contracts along the axial direction of the outer tube 2 to push the inner tube 3 The connected structure rises or pulls the structure connected to the inner pipe 3 to descend. When the inner pipe 3 cannot be retracted into the outer pipe 2 due to power failure or other reasons, the inner pipe 3 of the hand-rotating linear actuator can also be manually rotated, so that The inner tube 3 shrinks inwardly of the outer tube 2 along the axial direction of the outer tube 2 . The end of the outer tube 2 is provided with a support seat 4 for the inner tube 3 to pass through, and a support assembly 5 is provided between the support seat 4 and the inner pipe 3, and the support assembly 5 is fixed on the support seat 4. The support assembly 5 includes at least one The b...

Abstract

The invention discloses a hand-rotation type linear actuator. The hand-rotation type linear actuator comprises a machine shell, an outer pipe fixed to the machine shell and an inner pipe connected tothe interior of the outer tube in a sleeved mode, wherein the inner pipe rotates or stretch in the outer pipe, the end part of the outer pipe is provided with a supporting seat, a supporting assemblyfixed on a supporting seat is arranged between the supporting seat and the inner pipe, the supporting assembly comprises at least one bearing, and the at least one bearing is connected on the inner pipe in a sleeving mode. According to the hand-rotation type linear actuator, the inner pipe is radially positioned and axially guided through the supporting assembly, so that the radial force borne bythe inner pipe cannot influence the rotation of the inner pipe, a user can easily rotate the inner pipe to retract the inner pipe into the outer pipe during power failure, a structure connected with the inner pipe is lowered, and the use is more labor-saving, more convenient and faster.

Description

technical field [0001] The invention belongs to the field of linear actuators, in particular to a hand-rotating linear actuator. Background technique [0002] At present, hand-rotary linear actuators are widely used in various fields. The existing hand-rotary linear actuators guide the inner tube axially through the support seat and also radially position the inner tube. When the inner tube of the linear actuator pushes the object, the inner tube will be subjected to radial force. When the radial force on the inner tube is too large, the inner tube will press the support seat under the action of the radial force. When the inner tube needs to be turned by hand, because the friction between the inner tube and the support seat is too large, the inner tube cannot be rotated to retract into the outer tube, and the user experience is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hand-rotating linear actuator...
