Description
Technical field
The utility model relates to fastening piece, particularly relates to steel structure hexagon head bolt.
Background technique
Bolt, by head and screw rod (with an externally threaded cylindrical body) class fastening piece dimerous, needs and nut screw connection, for being fastenedly connected two parts with through hole.This Connecting format claims bolt to connect.As nut is screwed off from bolt, can make again these two parts separately, therefore bolt connection belongs to removably connect.
After bolt tightening on market, impacting force is there is not, after a long time use, because two are connected the operation vibration of part in the screw rod of bolt head towards face and the surface being connected part, bolt joint between them there will be loosening, and impact is connected the working stability of part.
In sum, for the defect of prior art, need steel structure hexagon head bolt especially, to solve the deficiencies in the prior art.
Model utility content
For in prior art to the deficiency that bolt in use exists, and bring very large inconvenience in the work of reality, and the utility model proposes steel structure hexagon head bolt, novel in design, elevator bolt stability after tightening, addresses the deficiencies of the prior art.
To achieve these goals, the utility model realizes by the following technical solutions:
Steel structure hexagon head bolt, comprise bolt shank and bolt head, the material that bolt shank and bolt head adopt is alloyed steel, tapping thread is offered above the inwall of bolt head, the both sides of bolt shank are provided with outside thread, smooth department between outside thread is set to limiting area, and bolt head is connected the outside thread of bolt shank by tapping thread.
Further, detachable connection is adopted between described bolt head and bolt shank.
Further, the shape of described bolt head is regular hexagon, and the surface of bolt head is provided with cross clamping groove.
The beneficial effects of the utility model are: this product structure is simple, easy to make, enhance the flexible performance of bolt, bolt head can be connected different bolt shank as required, and and connected piece between there is impacting force, long-time use, can not be loosened, practicability is excellent, novel in design, be a kind of well innovation scheme, have very much marketing prospect.
Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is the utility model steel structure hexagon head bolt structural representation.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
