Abstract
The utility model relates to a safety lifting hook. The lifting part of the safety lifting hook is a locked lifting rod, the upper end of a hook body has a vertical groove and the middle part of the locked lifting rod is clamped in the vertical groove and connected with the hook body by rivets. A safety device is arranged in the vertical groove of the locked lifting rod by an opening pin shaft which is sheathed with a torsion spring, and both ends of the torsion spring are respectively supported on the locked lifting rod and the safety device. A lug boss of the safety device is clamped by a notch of the locked lifting rod. The safety lifting hook is reliably locked and a rope can not be disengaged from the hook during use. The utility model can be widely used in lifting operations in various industries.
Description
The utility model relates to a kind of suspension hook, especially a kind of safety hook with locking.
The suspension hook of prior art does not mostly have closing appliance, even the suspension hook that has has closing appliance, but reliability is relatively poor, occurs rope unhook phenomenon in the hoisting process easily, and is very dangerous.
The purpose of this utility model provides a kind of safety hook, locking reliably.
The purpose of this utility model realizes as follows: this suspension hook also relates to coupler body and lifting part, the lifting part is the locking suspension rod, there is a vertical slot coupler body upper end, locking suspension rod middle part is clipped in the vertical slot, the locking suspension rod is connected with rivet with coupler body, with the opening bearing pin file protect is set in the vertical slot of locking suspension rod, is with torsion spring on the opening bearing pin, the two ends of torsion spring are supported on respectively on locking suspension rod and the file protect, and the boss of file protect is stuck on the breach of locking suspension rod.Under blocking, the center three of the center of the rivet between locking suspension rod and the coupler body, coupler body hook, locking suspension rod top lifting part substantially in a straight line.During use, press file protect, the breach that makes the boss of file protect leave the locking suspension rod is thrown off insurance, break locking suspension rod bottom off with the fingers and thumb itself and coupler body are thrown off, hang rope, at this moment, the center three of the center of rivet, coupler body hook, lifting part is out-of-line, one exert oneself slightly during lifting, locking suspension rod lower end just resilience is adjacent on the coupler body, and file protect is locked the locking suspension rod under the effect of torsion spring.Can certainly press off lock suspension rod bottom with have gentle hands makes it be adjacent on the coupler body file protect coupler lock then.
Owing in such scheme, adopted locking suspension rod and file protect, make this safety hook locking reliable, rope unhook phenomenon, safe ready can not appear in hoisting process.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the structural representation of first kind of embodiment of safety hook.
Fig. 2 is the structural representation of second kind of embodiment of safety hook.
Fig. 3 is the structural representation of the third embodiment of safety hook.
Embodiment 1:
The lifting part is locking suspension rod 6, and it is made of deadlock lever 9, suspension ring 7, nut 8 and pin 10, and deadlock lever 10 upper ends are inserted in the endoporus of suspension ring 7, screws in nut 8 on the threaded portion of the upper end of deadlock lever 10, and the two locks with pin 10.There is a vertical slot coupler body 1 upper end, locking suspension rod 6 middle parts are clipped in the vertical slot, be connected with rivet between locking suspension rod 6 and the coupler body 1, in the vertical slot of locking suspension rod 6, file protect 4 is set with opening bearing pin 3, on opening bearing pin 3, be with torsion spring 2, the two ends of torsion spring 2 are supported on respectively on locking suspension rod 6 and the file protect 4, and the boss of file protect 4 is stuck on the breach of locking suspension rod 6.
