Abstract

A mechanical self-locking actuating cylinder structure comprises a tail handle, a fixing locking sleeve barrel, a screw nut, a barrel body and a piston, wherein the tail handle is connected with the piston through screw thread and tightened through the screw nut, which are arranged inside the fixing locking sleeve barrel together; the fixing locking sleeve barrel is arranged inside the barrel body and is coaxial to the barrel body; the right end of the piston is provided with a front edge; and the tail handle is provided with a front edge at the edge; the left and the right sections of the fixing locking sleeve barrel are thin barrel body structures; the end parts of both ends are provided with axial front edges; four to eight narrow slits are opened along the axial direction from the heads of the left and the right ends; and the fixing locking sleeve barrel, the matched tail handle and the front edge at the head part of the piston are inclined surface. The mechanical self-locking actuating cylinder structure has the advantages of being light, reliable and practical. The structure has self-locking function within a certain range through reasonable structural design by using the elastic deformation of the structure; and the structure can realize the self-locking function and improves the economical efficiency without extra outer source power in the process of self-locking the actuating cylinder.

Description

technical field [0001] The invention relates to a mechanical structure, and in particular provides a mechanical self-locking cylinder structure. Background technique [0002] In the existing structure of the actuator in the mechanical industry, after the piston of the actuator reaches the predetermined position, in order to keep it in a balanced state, an external source of power must be provided to keep it in balance, which requires continuous energy consumption and poor economy; and When needed, a set of electromechanical locking device is added to realize the locking and unlocking of the actuator, which makes the structure and control complicated. [0003] Therefore, it is necessary to design an economical and reliable mechanical self-locking actuator structure, so that it can realize mechanical self-locking at a specific position without external power and control mechanism. At the same time, the mechanical self-locking actuator must be Lightweight, reliable, economical...
