The invention discloses a device with sliding safety locking and unlocking functions, and belongs to the technical field of machinery. Aiming at the task requirements of safe locking and unlocking of an operation tool, the sliding safe locking and unlocking device with the single-cycle height-variable rail and the torsion spring as the core is adopted, the rail rod is pulled by the pushing handle to slide on the single-cycle height-variable rail, the extension amount of the sleeve rod is controlled, and the safety locking and unlocking of the operation tool are achieved. And different extension amounts correspond to a locking state and an unlocking state of the equipment. The device is composed of a locking handle frame, a side plate, a single-circulation track module, a track rod, a double-torsion spring, a connecting rod and a sleeve rod. Wherein the single-circulation track module is composed of a single-circulation track outer wall, a single-circulation track and a single-circulation track inner wall. According to the extravehicular spacesuit, the problem that locking and unlocking operation of a tool locking device is difficult is solved, the rail rod can be firmly locked on the rail under the elastic action of the torsional spring, and an astronaut can conveniently judge whether the extravehicular spacesuit is installed in place or not through hand feeling after wearing the extravehicular spacesuit.

    一种具有滑动安全锁紧和解锁的装置,属于机械技术领域。本发明针对操作工具的安全锁紧与解锁的任务需求,采用由单循环变高度轨道以及扭簧作用为核心的滑动安全锁紧和解锁装置,通过推手拉动轨道杆在单循环变高度轨道上的滑动,实现对套杆伸出量的控制,不同的伸出量对应设备的锁紧与解锁2个状态。本发明由锁定手柄框架、侧板、单循环轨道模块、轨道杆、双扭簧、连杆和套杆组成;其中单循环轨道模块由单循环轨道外壁、单循环轨道和单循环轨道内壁组成。本发明解决了工具锁紧装置的锁紧、解锁操作困难的问题,扭簧的弹力作用使得轨道杆能被牢固锁紧在轨道上,方便航天员身着舱外航天服后通过手感判断是否安装到位。
