Abstract
The utility model relates to a security hook rigging, belonging to the field of mechanical design. The security hook rigging comprises a hook body and a hoisting part. The upper end of the hoisting part is provided with a locking hanging rod in the shape of a round hole; a vertical groove is arranged at the upper end of the hook body; the middle part of the locking hanging rod is clamped in a vertical groove and is connected with the hook body through a rivet; a protector is fixedly arranged in the vertical groove at the upper end of the hook body by an elastic cylindrical pin; a tension spring is sleeved on the elastic cylinder pin; both ends of the tension spring are respectively supported on the hook body and the protector; and a boss of the protector is clamped in a notch of the locking hanging rod. When the security hook rigging is used, the protector is pressed so that the boss departs from the notch of the locking hanging rod to release from the protector, and the locking hanging rod is broken off, so that the lower end part is released from the hook body and a rope is hung in; and a user slightly stresses the security hook rigging when hoisting, so that the lower end of the locking hanging rod rebounds to the tail end of the hook body and the convex-concave closing is realized. Meanwhile, the protector locks the locking hanging rod under the effect of the torsion spring.
Description
Technical field
The utility model relates to a kind of safety hook rigging, belongs to the machine design industry.
Background technology
The suspension hook rigging 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 reliability is relatively poor, and is very dangerous.
Summary of the invention
For addressing the above problem, the utility model provide a kind of easy to operate, use a kind of safety hook rigging flexible, simple in structure, can reliable locking lifting.
This suspension hook rigging relates to coupler body and lifting part, and the upper end of lifting part is the locking suspension rod that has circular hole, and there is a vertical slot coupler body upper end, and locking suspension rod 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, on elastic cylindrical pin, be with torsion spring, the two ends of torsion spring are supported on respectively on coupler body and the file protect, and the boss of file protect is stuck on the breach of locking suspension rod.Side in locking suspension rod upper end circular hole horizontal direction is provided with a symmetrical fan-shaped concave plane, is convenient to assemble other suspension hook rigging, and the lower end in fan-shaped concave plane is provided with an ellipse around boss, can control the open size of locking suspension rod; Terminal at the locking suspension rod, be provided with down " U " type groove, at the coupler body end one boss is set symmetrically, make the deadlock lever end under blocking, realize concavo-convex locking with the coupler body end.When closed, the center of the rivet between locking suspension rod and the coupler body, coupler body hook, locking suspension rod top circular hole center three are basically in a straight line.During use, press file protect and make its boss leave the breach disengagement insurance of locking suspension rod, break the locking suspension rod into two with one's hands; Hang rope, at this moment, the center three of the center that rivet, coupler body are linked up with, lifting part is out-of-line; One exert oneself slightly during lifting; Locking suspension rod lower end just recoils to the coupler body end, realizes concavo-convex closure, and file protect is locked the locking suspension rod under the effect of torsion spring simultaneously.
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.
Description of drawings:
Structural representation when Fig. 1 is a kind of safety hook rigging suspension rod locking;
Fig. 2 is the structural representation of a kind of safety hook rigging suspension rod when opening;
Fig. 3 is the structural representation of a kind of safety 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 safety hook rigging of the utility model, the lifting part is locking suspension rod 3, it is by falling " U " type groove 2, fan-shaped concave plane 4, ellipse around boss 5 formations.There is a vertical slot coupler body 10 upper ends; The middle part of locking suspension rod 3 is clipped in the vertical slot; Be connected with coupler body 10 usefulness rivets 6; In the vertical slot of coupler body 10, pass the centre hole of file protect 7 and torsion spring 9 with elastic cylindrical pin 8, the two ends of torsion spring 9 are supported on respectively on coupler body 10 and the file protect 7, and the boss of file protect 7 is stuck on the breach of locking suspension rod 3.
During use, press file protect 7 and make its boss leave the breach disengagement insurance of locking suspension rod 3, break locking suspension rod 3 off with the fingers and thumb, make the lower end be down " U " type groove 2 and throw off with coupler body 10 terminal boss 1; Pulling locking suspension rod 3 during lifting, locking suspension rod lower end fall " U " type groove 2 and just recoil to coupler body 10 terminal boss 1 place, realize concavo-convex closed and lockedly, and file protect 7 recoils to the indentation, there of locking suspension rod 3 automatically under the effect of torsion spring 9 simultaneously, once more locking.
The enforcement of the utility model does not receive the restriction of this instance, and other implementation method prior art capable of using beyond above-mentioned is also implemented with reference to the utility model accompanying drawing.
