The invention discloses a rotary limiting mechanism which comprises a supporting block, a reference block rotationally connected to the top of the supporting block, a supporting plate connected to the supporting block, a first connecting rod rotationally matched with the end, away from the supporting block, of the reference block, a second connecting rod rotationally matched with the first connecting rod and a push rod rotationally connected to the supporting plate. The end, away from the first connecting rod, of the second connecting rod is rotationally connected with the top of the supporting plate, and a limiting rod is rotationally connected between the second connecting rod and the push rod and provided with a limiting nose matched with the second connecting rod. The reference block is used for being connected with an external pressing mechanism, the push rod rotates to sequentially drive the limiting rod, the second connecting rod, the first connecting rod and the reference block to rotate in a linkage mode, the limiting nose of the limiting rod locks the second connecting rod and limits rotation of the second connecting rod, the reference block and other components, and the whole rotating limiting mechanism can be locked and loosened by rotating the push rod; therefore, the external pressing mechanism on the reference block can press and loosen the T-shaped stringer, and the operation is simple and convenient.

    本发明公开了一种旋转限位机构,包括:支撑块、转动连接在支撑块顶部的基准块、连接在支撑块上的支撑板、与基准块远离支撑块的端部转动配合的连杆一、与连杆一转动配合的连杆二以及转动连接在支撑板上的推杆,连杆二远离连杆一的端部与支撑板的顶部转动连接,连杆二与推杆之间转动连接有限位杆,限位杆设有与连杆二相配合的限位鼻。本发明的基准块用于连接外部压紧机构,推杆旋转可依次带动限位杆、连杆二、连杆一以及基准块联动旋转,限位杆的限位鼻对连杆二锁紧,并限制连杆二、基准块等部件的转动,旋转推杆即可实现旋转限位机构整体的锁紧和放松,从而实现基准块上的外部压紧机构对T型桁条的压紧和放松,操作简单方便。
