The invention relates to the technical field of lifting devices, and discloses a self-locking lifting device which comprises a lifting mechanism, a hanging mechanism, a self-locking mechanism, a transmission mechanism and an elastic piece. One end of the hanging mechanism is movably connected with the lifting mechanism, and the other end of the hanging mechanism is provided with a hook which is provided with a first opening area; the self-locking mechanism is connected to the first opening area in an openable and closable manner; the transmission mechanism is in transmission connection with the lifting mechanism and the self-locking mechanism; the elastic piece is propped between the hanging mechanism and the lifting mechanism; when the hook hangs an object and is stressed, the hook moves relative to the lifting mechanism in the first direction and compresses the elastic piece, and the self-locking mechanism closes the first opening area under the control of the hook and the transmission mechanism. The hook moves relative to the lifting mechanism in the second direction under the elastic action of the elastic piece when the hook hangs an object and is not stressed, and the self-locking mechanism opens the first opening area under the control of the hook and the transmission mechanism; the first direction is opposite to the second direction. The self-locking lifting device provided by the invention can be operated by one hand, and is convenient to operate.
本发明涉及提吊装置技术领域,公开了自锁式提吊装置,包括提吊机构、挂持机构、自锁机构、传动机构和弹性件;挂持机构的一端与提吊机构活动连接,另一端设有挂钩,挂钩设有第一开口区;自锁机构可开闭地连接在第一开口区;传动机构传动连接提吊机构和自锁机构;弹性件抵靠在挂持机构与提吊机构之间;其中,挂钩挂持物品受力时沿第一方向相对提吊机构移动并压缩弹性件,自锁机构在挂钩和传动机构的控制下封闭第一开口区;挂钩挂持物品不受力时在弹性件的弹力作用下沿第二方向相对提吊机构移动,自锁机构在挂钩和传动机构的控制下打开第一开口区;第一方向与第二方向的方向相反。本发明提供的自锁式提吊装置,可单手操作,操作便捷。
