Abstract

The utility model relates to a hook, in particular to a self-locking safety hook. The self-locking safety hook consists of a casing, a lifting ring, a lattice beam, a hook straight shank and hook bodies. The lifting ring is connected with the top end of the casing, the lattice beam is arranged inside the casing, and the hook straight shank is fixedly connected with the lower end of the lattice beam. The two hook bodies are symmetrical and in hinge connection with the lower end of the hook straight shank, a spring and a round lantern ring sleeve are arranged on the hook straight shank, the round sleeve is located under the spring, and the lower portion of the round sleeve extends out of the casing. The self-locking safety hook is simple in structure, safe and reliable, avoids unhooking and is capable of rotating under the condition of load bearing.

Description

The self locking safety suspension hook

Technical field

The utility model relates to suspension hook, particularly a kind of self locking safety suspension hook.

Background technology

At present, the oil field is single hook strip at jointed rod time institute use suspension hook has insurance card, because insurance card is all suppressed by iron plate;, very easily damage, break off relations easily; And existing suspension hook generally can not rotate in load-bearing, and steel rope is tied a knot easily when rotating the installation parts, safety misadventure occurs.

Summary of the invention

The purpose of the utility model is to provide a kind of auto-lock function, safe and reliable, self locking safety suspension hook that can under the situation of load-bearing, rotate of having.

The technical scheme of the utility model is:

The self locking safety suspension hook comprises overcoat, suspension ring, Gou Liang, suspension hook staight shank and suspension hook composition, and suspension ring connect outer set upper side; The ditch beam is set in the overcoat, and the suspension hook staight shank is captiveed joint with the Gou Liang lower end, and two suspension hooks and suspension hook staight shank lower end are articulated and connected; Two suspension hook symmetries; Spring is enclosed within on the suspension hook staight shank with the circle collar, and the circle cover is positioned at the spring below, and overcoat is stretched out in the bottom of circle cover.

Concrete, suspension ring are connected with overcoat through pressure bearing.

Concrete, the bottom of suspension hook staight shank is provided with convexity.

The utility model utilizes move up circle cover of external force before lifting cargo, separately double hook after goods hangs up suspension hook, removes external force, and circle is enclosed within the effect of spring and resets, and it is closed voluntarily to make double hook close up realization.

The utility model is simple in structure, and is safe and reliable, prevented the unhook phenomenon, can under the situation of load-bearing, rotate.

Description of drawings

Fig. 1 is the structural representation of the utility model.

1 overcoat, 2 ditch beams, 3 springs, 4 pressure bearings, 5 suspension hook staight shanks, 6 suspension hooks, 7 suspension ring, 8 circle covers, 9 convexities.

The specific embodiment

The self locking safety suspension hook, suspension ring 7 are connected with overcoat 1 through pressure bearing 4, and ditch beam 2 is set in the overcoat 1; Suspension hook staight shank 5 is captiveed joint with ditch beam 2 lower ends, and two suspension hooks 6 are articulated and connected two suspension hook 6 symmetries with suspension hook staight shank 5 lower ends; Suspension hook 6 tops are provided with protruding 9; Spring 3 overlaps 8 ring sets on suspension hook staight shank 5 with circle, and circle cover 8 is positioned at spring 3 belows, and overcoat is stretched out in the bottom of circle cover 8.

Should be noted that at last: above embodiment only in order to the explanation the utility model technical scheme but not to its restriction; Although with reference to preferred embodiment the utility model has been carried out detailed explanation, the those of ordinary skill in affiliated field is to be understood that: still can make amendment to the specific embodiment of the utility model perhaps is equal to replacement to the part technical characterictic; And not breaking away from the spirit of the utility model technical scheme, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
