The invention relates to a repeatable pressing and releasing mechanism which comprises a driving assembly and a driving hinge, one side of the driving assembly is movably connected with a driving rod, the driving hinge is arranged at one end of the driving rod, one side of the driving hinge is movably connected with a linkage rod, a fixed hinge is arranged below the linkage rod, and the fixed hinge is arranged below the linkage rod. One side of the fixed hinge is movably connected with a driven rod, and one end of the driven rod is movably connected with a driven hinge. The repeatable pressing and releasing mechanism has the beneficial effects that the repeatable pressing and releasing mechanism is provided with the second fixed hinge, and through the installed second passive rod and the second fixed hinge, an extra firer device or a non-firer device does not need to be arranged as a power source, the driving assembly is used as the power source, and pressing and unlocking releasing of one or more pressing points can be achieved. The pressing force can be guaranteed according to the torque of the driving assembly, the thrust of the sliding block and the structural design of the sliding block, and the stroke of the taper pin can also be guaranteed according to the size design of the four-bar mechanism.
本发明涉及一种可重复压紧释放机构,包括驱动组件和驱动铰链,所述驱动组件的一侧活动连接有驱动杆,所述驱动铰链设置于驱动杆的一端,且驱动铰链的一侧活动连接有连动杆,所述连动杆的下方设置有固定铰链,且固定铰链的一侧活动连接有被动杆,并且被动杆的一端活动连接有被动铰链。本发明的有益效果是:该可重复压紧释放机构安装有II号固定铰链,通过安装的被动二号杆与二号固定式铰链,不需要额外配置火工装置或非火工装置作为动力源,利用驱动组件作为动力源,可以实现一个或多个压紧点的压紧和解锁释放。压紧力可以根据驱动组件的扭矩和滑块的推力,以及滑块结构设计来保证,锥销行程也可以根据四连杆机构的尺寸设计来保证。
