Self-locking and self-unlocking mechanical device

Abstract

The invention discloses a self-locking and self-unlocking mechanical device. The device comprises an upper arm supporting plate, a front arm supporting plate, a fixed plate, a movable plate, a baffle,a left guide wheel, a right guide wheel and a lock pin assembly. The front side of the lock pin assembly is rotationally connected to the middle of the rear side of the movable plate. Tension springswhich surround the guide wheels are arranged between the rear part of the lock pin assembly and the upper part of the fixed plate. The lower side edge and the front side edge of the fixed plate are of an arc-shaped structure, and a clamping groove is formed in the lower portion of the front side of the arc-shaped structure. A stepped groove structure which used for driving the lock pin assembly is formed in the rear side edge of the baffle. A one-way locking guide-out groove, a curve structure located above the one-way locking guide-out groove and a linkage block located at the uppermost endof the curve structure are arranged on the upper portion of the rear side edge of the movable plate, and the linkage block protrudes rightwards and is located above the rear end of the baffle. The self-locking and self-unlocking mechanical device is novel in design, unique and simple in structure, lower in manufacturing cost, high in reliability and convenient to operate, can be applied to an elbow joint, is used for relieving the stress of the elbow joint, is convenient to wear and does not affect the daily arm movement.

Description

technical field [0001] The invention belongs to the technical field of mechanical exoskeleton, in particular to a self-locking and self-unlocking mechanical device. Background technique [0002] Due to the limitation of the site, inspection workers often hold their work laptops with one hand and operate them with one hand. With different inspection routes, they are seriously exhausted every day. When mothers take their young children out for a walk, it is inevitable that the children will ask for hugs due to physical strength and other reasons. It's not every time you go out with a stroller or baby seat (a baby seat that straps to your body). And in many factories, workers often need to flex and extend their arms (including upper arms and forearms) and lift them to hold objects. The elbow joints are under a lot of force. Over time, the elbow joints will be overworked and damaged. In the elbow rehabilitation treatment of the orthopedic department of the hospital, the patien...

AI Technical Summary

Problems solved by technology

And in many factories, workers often need to bend and extend their arms (including upper arms and forearms) and lift them to hold objects. The elbow joint is under a lot of force. Over time, the elbow joint will be overworked and damaged.

In the elbow rehabilitation treatment of the orthopedic department of the hospital, the patient wears a device for fixing the elbow, but this device can only fix the elbow at an angle, cannot rotate, and cannot bear the pulling force of heavy objects

At present, there is no relevant design of this kind of exoskeleton fixator that automatically locks and unlocks the fixed angle of the human elbow joint at home and abroad.
