The invention discloses a lifting hook. According to the lifting hook, a connecting hole of an S-shaped hook is movably connected with a hanging lug of a base rod through a connecting shaft, and whena bearing bend of the S-shaped hook is hung on a heavy object, the S-shaped hook and the hanging lug of the base rod move relatively, so that a locking bend of the S-shaped hook and a cylindrical sealof the base rod are closed and matched to form a locking hook; when the base rod is lifted up, the bearing bend of the S-shaped hook loses the support of the heavy object, under the action of the self weight of the S-shaped hook, the S-shaped hook moves downwards along the hanging lug of the base rod, and the locking bend of the S-shaped hook is disengaged from the cylindrical seal of the base rod; and due to the structural characteristic of the S-shaped hook, the gravity center of the S-shaped hook is outside, the S-shaped hook turns to the outside, an opening of the lifting hook is opened,and the lifting hook is separated from the heavy object, so that the defect that a lifting hook of an existing normally-closed anti-falling blocking piece is separated from a hung object only when thenormally-closed anti-falling blocking piece is removed by hand is overcome, and meanwhile the technical problem that due to the fact that an opening lifting hook is used, the risk of safety accidentsis caused is solved.

    本申请公开了一种吊钩,S形弯钩的连接孔通过连接轴与基杆的挂耳活动连接,当S形弯钩的承力弯挂于重物上时,S形弯钩与基杆的挂耳相对运动,使S形弯钩的锁定弯与基杆的圆柱形封口闭合配合形成闭锁吊钩,上抬基杆时S形弯钩的承力弯失去重物的支撑,在S形弯钩自重的作用下,S形弯钩沿基杆的挂耳向下运动,S形弯钩的锁定弯从基杆的圆柱形封口脱离,因S形弯钩自身结构特性,S形弯钩的重心在外侧,而向外侧翻转,挂钩开口打开,与重物脱离,解决了现有的常闭防脱挡片的吊钩需用手解除常闭脱挡片才能与挂物脱离的缺陷,同时避免由于使用开口吊钩带来安全事故的风险的技术问题。
