Abstract
The invention discloses a hexagonal head bolt for a steel structure. The hexagonal head bolt comprises a bolt rod and a bolt head, wherein the bolt rod and the bolt head are made of alloy steel, tapping threads are arranged on the inner wall of the bolt head, outer threads are arranged on two sides of the bolt rod, the smooth portions among the outer threads serve as limiting areas, and the bolt head is connected with the bolt rod through the tapping threads and the outer threads of the bolt rod. The hexagonal head bolt is simple in structure and convenient to manufacture, the flexible performance of the bolt is improved, the bolt head can be in linkage with different bolt rods according to the demands, pressing force exists between the bolt and a connected part, and the hexagonal head bolt is not loosened after being used for a long period of time, is excellent in practical performance and novel in design, is a good innovation scheme and has wide market promotion prospect.
Description
Technical field
The present invention relates to fastening piece, particularly relate 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.
Summary of the invention
For in prior art to the deficiency that bolt in use exists, and bring very large inconvenience in the work of reality, the present invention proposes steel structure hexagon head bolt, and novel in design, elevator bolt stability after tightening, addresses the deficiencies of the prior art.
To achieve these goals, the present invention 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 invention has the beneficial effects as follows: 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 present invention is described in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is steel structure hexagon head bolt structural representation of the present invention.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
See Fig. 1, steel structure hexagon head bolt, comprise bolt shank 110 and bolt head 100, the material that bolt shank 110 and bolt head 100 adopt is alloyed steel, tapping thread 120 is offered above the inwall of bolt head 100, the both sides of bolt shank 110 are provided with outside thread 130, smooth department between outside thread 130 is set to limiting area 140, and bolt head 100 is connected the outside thread 130 of bolt shank 110 by tapping thread 120.
In addition, adopt detachable connection between bolt head 100 and bolt shank 110, the shape of bolt head 100 is regular hexagon, and the surface of bolt head 100 is provided with cross clamping groove.
The present invention is effective is: 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.
More than show and describe basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
