Locking mechanism of strut device

Abstract

The invention relates to a strut design, in particular to a locking mechanism of a strut device. According to the invention, the inner wall of a sleeve structure of an end cover is provided with a first ring groove; one end of a piston rod is installed in the sleeve structure of the end cover; a lock rod sleeve is axially installed in the cavity of the piston rod; one end of lock rod is installedin the lock rod sleeve and is capable of performing relative movement in an axial direction, and the other end of lock rod is fixedly mounted in the end cover; a support bush sleeves the piston rod; one end, close to a limiting ring, is provided with an annular notch; the support bush is fixed on the lock rod by a pin and can move axially with the lock rod; a snap ring has a locked state and an unlocked state; when the support bush moves towards the limiting ring, the snap ring is squeezed to the annular notch, and the annular notch, the limiting ring and the first ring groove clamp the snap ring, so the snap ring is in the locked state; and when the support bush moves away from the limiting ring, the snap ring is separated from the annular notch and tightly sleeves the piston rod, so thesnap ring is in the unlocked state.

Description

technical field [0001] The invention relates to a strut design, in particular to a locking mechanism of a strut device. Background technique [0002] The load-bearing structure of common struts or retractable actuators is often connected by threads, and the force of the threads is complicated. The manufacturing process has a great influence on the quality of the threads. Moreover, active locking cannot be realized, and it will be damaged after locking. Risk of unintentional unlocking due to pressure pulses or overloads. [0003] Therefore, it is desirable to have a technical solution to overcome or at least alleviate at least one of the above-mentioned drawbacks of the prior art. Contents of the invention [0004] The object of the present invention is to provide a locking mechanism for the brace device, which is used to control the connection or disconnection of the load-bearing structure of the brace device. [0005] Technical scheme of the present invention is: [00...
