Abstract

The invention relates to a repeated locking and releasing mechanism, in particular to a linkage type space repeated locking and releasing mechanism. The linkage type space repeated locking and releasing mechanism aims at solving the problem that reliability and controllability of an existing locking and releasing mechanism in the locking process are poor. The linkage type space repeated locking and releasing mechanism comprises a repeatable locking and releasing mechanism and a linkage driving mechanism. The repeatable locking and releasing mechanism comprises a locking mechanism and a locked assembly. The locking mechanism comprises a connection rod, a rocker connection rod shaft, a rocker, a lock hook rocker shaft, a lock hook, a locking shell, a bearing base, a worm, a worm gear, a first transition gear, a first transition gear shaft, a second transition gear shaft, a second transition gear, a crank gear, a crank connection rod shaft, a rocker shaft and a crank gear shaft. The linkage type space repeated locking and releasing mechanism is used in the aerospace field.

Description

technical field [0001] The invention relates to a repetitive locking and releasing mechanism, in particular to a linked space repetitive locking and releasing mechanism, which belongs to the field of aerospace. Background technique [0002] In the field of aerospace, pyrotechnic devices such as explosive bolts and pyrotechnic cutters are mostly used for the connection and separation of spacecraft and payloads. Although this device has the characteristics of simple structure and high reliability, it cannot realize the on-orbit repeated locking function. The huge impact of pyrotechnic separation has a serious impact on the attitude and precision control of the space control platform. [0003] In recent years, with the development of space station construction and space detection technology, the space-to-earth shuttle system has an increasingly strong demand for locking-release-relocking of transported large-scale, heavy-duty materials and aerospace vehicle doors. There are al...
