Abstract
The utility model relates to a rotary lifting hook rigging which belongs to the field of machine design. The lifting hook rigging comprises to four parts, namely a rotary hoisting ring, a locking lever, a hook body and a protector. A through hole is arranged in the centre of the bottom part of the rotary hoisting ring; a thread is machined at the upper end of the locking lever; an inverted U-shaped groove is machined at the tail end of the locking lever; the upper end of the locking lever penetrates into the through hole of the rotary hoisting ring and a flat gasket; a slot nut is screwed into a thread part and locked by an elastic cylindrical pin; the middle part of the locking lever is clamped in a vertical slot at the upper end of the hook body and connected by a rivet; the protector and a torsional spring are fixed by the elastic cylindrical pin in the vertical slot at the upper part of the hook body; two ends of the torsional spring are respectively supported on the hook body and the protector, and a lug boss of the protector is locked in a gap of the locking lever. When the rotary lifting hook rigging is used, the protector is pressed to enable the lug boss to depart from the gap of the locking lever so as to be separator from the protector; the locking lever is pulled open, a rope is hung on the lifting hook rigging, and the lower end of the locking lever rebounds to the tail end of the hook body by a little force during lifting to achieve concave and convex closing.
Description
Technical field
The utility model relates to a kind of spin safe suspension hook rigging, belongs to the machine design industry.
Background technology
The shackle 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.
Summary of the invention
For addressing the above problem, the utility model provide a kind of easy to operate, use flexible, simple in structure, can rotate, a kind of spin safe suspension hook rigging of reliable locking lifting.
The purpose of the utility model realizes as follows: this suspension hook rigging relates to rotation suspension ring, deadlock lever, coupler body and file protect four parts; Side in rotation suspension ring horizontal direction is provided with similar oval-shaped symmetrical concave plane; Be convenient to assemble other suspension hook rigging, the bottom of rotation suspension ring is provided with through hole, is provided with screw thread in the upper end of deadlock lever; The screw thread of deadlock lever upper end pass behind the through hole, plain cushion of rotation suspension ring with the grooved nut through elastic cylindrical pin locking; Establish a vertical slot in the coupler body upper end, the deadlock lever middle part is clipped in the vertical slot, is connected with rivet with coupler body; In the vertical slot of coupler body upper end with the fixing file protect of elastic cylindrical pin; Be with torsion spring on the elastic cylindrical pin; The two ends of torsion spring are supported on respectively on coupler body and the file protect; The boss of file protect is stuck on the breach of deadlock lever, the coupler body end be provided with one with the terminal cooresponding boss of " U " type groove that falls of deadlock lever, make the two under blocking, realize concavo-convex locking.When closed, rotation suspension ring, deadlock lever, rivet and coupler body hook center are basically in a straight line.During use, press file protect and make its boss leave the breach disengagement insurance of deadlock lever, draw back deadlock lever; Hang rope; It is out-of-line that rotate suspension ring, deadlock lever, rivet, coupler body hook center this moment, and slightly one firmly, the deadlock lever lower end just recoils to the coupler body end during lifting; Realize concavo-convex closure, file protect is locked deadlock lever under the effect of torsion spring simultaneously.
Owing in such scheme, adopted deadlock lever and file protect, make this spin safe suspension hook locking reliable, rope unhook phenomenon, safe ready can not appear in hoisting process.
Description of drawings:
Structural representation when Fig. 1 is a kind of spin safe suspension hook rigging locking;
Fig. 2 is the structural representation of a kind of spin safe suspension hook rigging when opening;
Fig. 3 is the structural representation of a kind of spin safe suspension hook rigging " U " type groove;
The specific embodiment
Do further description with reference to accompanying drawing 1, accompanying drawing 2,3 pairs of the utility model of accompanying drawing, so that the public grasps the implementation method of the utility model better.
The described a kind of spin safe suspension hook rigging of the utility model, by rotation suspension ring 4, grooved nut 7, elastic cylindrical pin 6, plain cushion 8, deadlock lever 3, coupler body 13 constitutes.Rotation suspension ring 4 are provided with oval symmetrical concave plane 5; The screw thread of deadlock lever 3 upper ends penetrates through hole, plain cushion 8 backs of rotation suspension ring 4 and locks through elastic cylindrical pin 6 with grooved nut 7; Coupler body 13 lower ends are provided with boss 1; " U " type groove 2 is corresponding with deadlock lever 3 lower ends; The middle part of deadlock lever 3 is clipped in the vertical slot, is connected with coupler body 13 usefulness rivets 9, in the vertical slot of coupler body 13, passes the centre hole of file protect 10 and torsion spring 12 with elastic cylindrical pin 11; The two ends of torsion spring 12 are supported on respectively on coupler body 13 and the file protect 10, and the boss of file protect 10 is stuck on the breach of deadlock lever 3.
During use, press file protect 10 and make its boss leave the breach disengagement insurance of deadlock lever 3, break deadlock lever 3 off with the fingers and thumb, make the lower end be down " U " type groove 2 and throw off with coupler body 13 lower end boss 1; During lifting, pulling deadlock lever 3, its lower end is fallen " U " type groove 2 and is recoiled to coupler body 13 lower end boss 1 place, realizes concavo-convex closed and lockedly, and file protect 10 recoils to the indentation, there of locking suspension rod 3 automatically under the effect of torsion spring 12 simultaneously, once more locking.
Other implementation method prior art capable of using is also implemented with reference to the utility model accompanying drawing.
