The embodiment of the invention provides a rotation limiting mechanism of a seat. The rotation limiting mechanism comprises a rotating part, a supporting part and an operating part. The supporting part is pivoted with the rotating part; a plurality of first limiting keys is formed on the supporting part. The multiple first limiting keys are arranged at intervals in the rotating direction of the rotating part. The operating part is pivoted with the rotating part; and a second limiting key is formed on the operating part. The operating part can rotate relative to the rotating part so that the second limiting key and the first limiting key can be locked or unlocked. The second limiting key and the first limiting key are locked or unlocked through the operating part, so that the rotating partis controlled to rotate or be static relative to the supporting part, and operation is easy and convenient. The embodiment of the invention further provides the seat. The seat comprises the rotary limiting mechanism and a seat framework. The seat framework is connected with the rotating part and can rotate synchronously with the rotating part. The embodiment of the invention further provides an engineering vehicle. The engineering vehicle comprises the seat, a chassis, a rotary table and a cantilever.

    本申请实施例一方面提供一种座椅的旋转限位机构,旋转限位机构包括转动件、支撑件以及操纵件。支撑件与转动件枢接。支撑件上形成有多个第一限位键。多个第一限位键沿转动件的转动方向间隔设置。操纵件与转动件枢接。操纵件上形成有第二限位键。操纵件能够相对于转动件转动,以使第二限位键与第一限位键锁止或解锁。通过操纵件使得第二限位键与第一限位键锁止或解锁,从而控制转动件相对于支撑件转动或静止,操作简便。本申请实施例另一方面提供一种座椅,包括上述旋转限位机构以及座椅骨架。座椅骨架与转动件连接,座椅骨架能够与转动件同步转动。本申请实施例另一方面还提供一种工程车辆,工程车辆包括上述座椅、底盘、转台以及悬臂。
