Abstract

The utility model provides a lifting hook. The lifting hook comprises a hook neck and two hook bodies, wherein the bottom ends of the two hook bodies and the hook neck are connected to respectively form 50-DEG bottom included angles; a first hook head and a second hook head are formed at the bottom included angles; the two hook bodies are symmetrical with each other by taking the hook neck as the center. The lifting hook is characterized in that a branch is further arranged on each hook body, is arranged on the center of each hook body and is capable of forming a 100-degree central included angle with each hook body; a third hook head and a fourth hook head are formed at the central included angles; each branch is in the shape of one fourth of a circular arc, so that problems that a distance between conventional hook heads cannot be adjusted, flexibility is bad and the like are solved.

Description

A kind of suspension hook

Technical field

The utility model relates to a kind of suspension hook.

Background technology

Suspension hook is load-engaging device the most frequently used in modern society, is also modal a kind of suspender in construction trade.Suspension hook can be divided into single hook and double-hung by shape, and wherein single hook generally is used for less hoisting capacity, and double-hung is multiplex in larger hoisting capacity.At present the most frequently used double-hung is simple in structure, and the distance between the double-hung gib head is fixed, and can't regulate, and alerting ability is inadequate.In lifting process, because contoured article and density that double-hung hangs below are different, and the distance between the double-hung gib head is fixed, and has the unbalanced hidden danger of article.

The utility model content

The problems such as the purpose of this utility model is to provide a kind of suspension hook, and the distance that solves between existing suspension hook gib head can't be regulated, and alerting ability is inadequate.

The utility model provides a kind of suspension hook, comprise a hook neck, two coupler bodies, the bottom of described two coupler bodies and hook neck are connected to 50 ° of bottom angles, the angle, bottom forms the first gib head and the second gib head, and two coupler bodies are symmetrical centered by the hook neck, it is characterized in that also being provided with a branch on described each coupler body, branch is positioned at the coupler body center and becomes 100 ° of middle part angles with coupler body, and the angle, middle part forms the 3rd gib head and the 4th gib head.Because arc can reduce the loss of suspension hook, thus branch be shaped as the quadrntnt arc, two branches centered by the hook neck symmetrically.

Further, article can be suspended on simultaneously the first gib head of forming between the bottom of two coupler bodies and hook neck and the second gib head place.

Further, article can be suspended on simultaneously the 3rd gib head that forms between two branches and coupler body and the 4th gib head place.

Realized that by four gib heads selecting suspension hook the distance between gib head is adjustable.

The beneficial effects of the utility model are: this suspension hook is simple in structure, and is easy to operate, uses more flexible.

Description of drawings

Fig. 1 is the constructional drawing of existing double-hung;

Fig. 2 is the constructional drawing of the utility model suspension hook.

The mark implication of accompanying drawing is as follows:

1: the hook neck; 2: coupler body; 3: branch; 4: the first gib heads; 5: the second gib heads; 6: the three gib heads; 7: the four gib heads.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment, technical solutions of the utility model are described in further detail, so that those skilled in the art can better understand the utility model and being implemented, but illustrated embodiment is not as to restriction of the present utility model.

As shown in Figure 1, be the constructional drawing of existing double-hung, the distance between the double-hung gib head is fixed, and can't regulate, and alerting ability is inadequate.

Fig. 2 is the constructional drawing of the utility model suspension hook, comprise a hook neck 1, two coupler bodies 2, the bottom of described two coupler bodies 2 and hook neck 1 are connected to 50 ° of bottom angles, the angle, bottom forms the first gib head 4 and the second gib head 5, two coupler bodies 2 are symmetrical centered by hook neck 1, it is characterized in that described each coupler body 2 also is provided with a branch 3, branch 3 be positioned at coupler body 2 centers and with 2 one-tenth 100 ° of coupler bodies middle parts angles, the angle, middle part forms the 3rd gib head 6 and the 4th gib head 7, branch 3 is shaped as the quadrntnt arc, two branches 3 centered by hook neck 1 symmetrically.

Further, article can be suspended on simultaneously the first gib head 4 of forming between the bottom of two coupler bodies 2 and hook neck 1 and the second gib head 5 places.

Further, article can be suspended on simultaneously between two branches 3 and coupler body 2 the 3rd gib head 6 that forms and the 4th gib head 7 places.

The suspension hook that the utility model provides is simple in structure, and is easy to operate, uses more flexible.

These are only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification sheets and accompanying drawing content to do; perhaps directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
