The invention relates to the technical field of lifting appliances, in particular to a self-locking lifting appliance. Comprising a lifting appliance seat, a pull sleeve and a plurality of hook claws, the lifting appliance seat and the pull sleeve are both cylindrical, and the pull sleeve is movably matched with an inner cavity of the lifting appliance seat; a plurality of first connecting seats are arranged on the circumferential outer wall of the lifting appliance seat, and a plurality of second connecting seats are arranged on the circumferential outer wall of the pull sleeve; a connecting hole is formed in one end of the hook claw, and the connecting hole is movably matched with the first connecting seat; the hook claw is further provided with a hinge hole, and the hinge hole is matched with the second connecting base in a hinged mode. Aiming at the technical problem that a traditional lifting appliance is poor in lifting effect, the lifting appliance is based on the lifting appliance seat and the pull sleeve which are of a cylindrical structure, the hook claws are arranged in the circumferential directions of the lifting appliance seat and the pull sleeve, so that the end part of the shaft component can extend into an inner cavity of the pull sleeve, and a better lifting effect of the shaft component can be achieved.
本发明涉及吊具技术领域,具体涉及一种自锁式吊具。包括吊具座、拉套和若干勾爪,所述吊具座和拉套均呈筒状,所述拉套与吊具座的内腔活动配合;所述吊具座周向外壁上设置有若干第一连接座,所述拉套周向外壁上设置有若干第二连接座;所述勾爪一端设置有连接孔,所述连接孔与第一连接座活动配合;所述勾爪上还设置有铰接孔,所述铰接孔与第二连接座铰接配合。针对传统吊具吊装效果不好的技术问题,本发明基于筒状结构的吊具座和拉套,将勾爪设置于吊具座和拉套的周向,使得轴类构件的端部可以伸入拉套内腔,可以起到轴类构件更好的吊装效果。
