Abstract
The utility model relates to the technical field of fastener connection, in particular to a high-strength bolt for small space. The high-strength bolt comprises a bolt body and a nut, and the bolt body comprises a bolt head and a bolt bar. The bolt head is round, and the nut is welded on the bolt head. The high-strength bolt for the small space can be used in narrow space and on large stress occasions.
Description
Technical field
The utility model relates to fastening piece interconnection technique field, particularly a kind of little space high-strength bolt.
Background technique
The use of bolt is very general, and structural type is varied.Bolt connecting device commonly used satisfies in the larger situation of installing space fully at present, but in narrow and small occasion, because the tool wrench operating space is not enough, particularly stressed larger high-strength bolt is when beating moment, and the operating space deficiency causes easily connecting that operational difficulties is time-consuming even may not realize.
The model utility content
The purpose of this utility model provides a kind of high-strength bolt that can use under small space, stressed large occasion.
The technological scheme that the utility model adopts is:
A kind of little space high-strength bolt comprises screw bolt and nut, and described bolt comprises bolt head and bolt shank, and described bolt head is circular, and described nut-welding is on described bolt head.
Further, have shrinkage pool on the described bolt head, the leg of described nut places in the described shrinkage pool.
The utlity model has following advantage:
The combination of the existing bolt connection standard spare of the utility model utilization has solved the bolton connectivity problem under the narrow and small occasion in operating space well.The utility model is simple in structure, easy for installation, has avoided adopting and has made the drawback that bolt is time-consuming and quality of processing is not high fully by oneself.
Description of drawings
The little space that Fig. 1 provides for the utility model embodiment structural representation of high-strength bolt;
The little space that Fig. 2 provides for the utility model embodiment structural representation of bolt in the high-strength bolt;
The little space that Fig. 3 provides for the utility model embodiment structural representation of nut in the high-strength bolt.
Embodiment
Below in conjunction with drawings and embodiments the utility model is described in further detail.
Referring to figs. 1 through Fig. 3, the utility model embodiment provides a kind of little space high-strength bolt, comprises bolt 1 and nut 2.Wherein, bolt 1 comprises bolt head 4 and bolt shank 3.Bolt head 4 is circular, and nut 2 is welded on the bolt head 4.Have shrinkage pool 5 on the bolt head 4, the leg 6 of nut 2 places in the shrinkage pool 5.
The utility model embodiment's high-strength bolt adopts spanner to operate, and utilizes the combination of existing bolt connection standard spare, has solved well the bolton connectivity problem under the narrow and small occasion in operating space.The utility model example structure is simple, easy for installation, has avoided adopting and has made the drawback that bolt is time-consuming and quality of processing is not high fully by oneself.
It should be noted last that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
