The invention discloses a multi-locking self-locking folding connector which comprises a first connecting part, a second connecting part and a locking handle, wherein one side of the first connecting part and one side of the second connecting part are hinged through a hinge shaft, and the locking handle is hinged to the hinge shaft through an eccentric cam. The buckling position is arranged on the inner side of the second connecting part relative to the hinge shaft, the self-locking assembly is arranged on the inner side of the first connecting part, and a linkage piece of the self-locking assembly abuts against the eccentric cam; when the first connecting part rotates to be coaxially connected with the second connecting part, the first elastic piece generates self-locking elastic force to enable the first lock catch to be connected with the buckling position in a buckling manner, so that the connector is switched to a self-locking state; a second lock catch and a second elastic piece are arranged on the inner side face, facing the first connecting part, of the locking handle. When the connector is in a self-locking state and rotates to be attached to the outer side of the first connecting part, the locking handle conducts primary locking, the second lock catch is connected with the first connecting part in a limiting mode to conduct secondary locking, and the direction of locking elastic force is the same as the direction of the center axis of the first connecting part. The overall structure is simple and use is safe and reliable.

    本发明公开一种多重锁定的自锁折叠连接器,包括:一侧通过铰接轴铰接的第一连接部和第二连接部,通过偏心凸轮与铰接轴铰接的锁定手柄;相对铰接轴设在第二连接部内侧的扣合位,设在第一连接部内侧的自锁组件,自锁组件的联动件与偏心凸轮抵接;在第一连接部转动至与第二连接部同轴连接时,第一弹性件产生自锁弹力让第一锁扣与扣合位扣合相连,以使连接器切换至自锁状态;锁定手柄朝向第一连接部的内侧面设有第二锁扣和第二弹性件;锁定手柄在连接器处于自锁状态下转动至贴合在第一连接部外侧时进行一次锁定,第二锁扣与所述第一连接部限位相连进行二次锁定,且锁止弹力的方向与第一连接部的中心轴同向。整体结构简单且使用安全可靠。
