A combined adjustable grid rudder unfolding and locking mechanism comprises a grid rudder, a rudder plate, a locking block, a locking device, a twisting piece device, a left unfolding shaft and a right unfolding shaft, wherein the twisting piece device is composed of a twisting piece retainer, twisting pieces, cushion blocks and bolts. By using different materials and numbers of twisting piece groups, unfolding moments of different sizes can be provided for unfolding of the grid rudder. The locking device is composed of a retainer, a guide rail, a spring pin, a spring, a cover plate and the like, the spring pin moves in the retainer, the T-shaped guide rail limits rolling of the spring pin in the retainer and plays a guiding role, one end of the spring is inserted into a cylindrical hole in the tail end of the spring pin, one end of the spring is connected to a guide cylinder on the cover plate in a sleeving mode, and spring bending instability can be avoided. The preset function is achieved through combination of multiple parts, and the purpose of adjusting the product performance of the mechanism is achieved through replacement of key parts and number changes so as to meet the requirements of different use environments.

    一种组合可调式栅格舵展开锁定机构,包括栅格舵、舵盘、锁定块、锁定装置、扭片装置、左展开轴、右展开轴。其中扭片装置由扭片保持架、扭片、垫块和螺栓组成,通过使用不同材料、数量的扭片组能够为栅格舵展开提供不同大小的展开力矩。锁定装置由保持架、导轨、弹簧销、弹簧、盖板等组成,弹簧销在保持架内移动,T字形导轨限制弹簧销在保持架内的滚转并起到导向作用,弹簧一端插入弹簧销尾端的圆柱孔,一端套接在盖板上的导向圆柱上,能够保持弹簧不发生弯曲失稳。本发明通过多个零件的组合实现预定功能,通过关键零件的更换以及数量变化达到调节机构产品性能的目的,以适应不同使用环境的需求。
