Abstract
The present invention relates to a kind of special fixing bolts, including integrally formed bolt head and screw rod, the screw rod is equipped with rotation screw thread, cross recess at the top of the bolt head, the bolt head side is equipped with the rotating hole being staggered, the rotating hole runs through bolt head, and the rotation screw thread is equipped with wearing layer, and the screw rod tail is equipped with pointed nose.Advantage is: cross recess and rotating hole are used cooperatively, and can be reduced its to avoid the excessive use of cross recess and be worn probability.
Description
Technical field
The present invention relates to concrete construction technical fields, more particularly to a kind of special fixing bolt.
Background technique
Bolt is needed to be connected through a screw thread with nut and is cooperated by head and screw rod fastener dimerous,
For being fastenedly connected two parts for having through-hole.During bolt is tightened and is unscrewed, it is often necessary to use tweezers and spiral shell
Bolt is cooperated, but permanent in use, the rotating hole on bolt is prone to wear, the bolt after abrasion cannot carry out it
It uses, causes waste.
Therefore, it is necessary to seek the new technology of one kind to solve the above problems.
Summary of the invention
The object of the present invention is to provide a kind of special fixing bolts.
To achieve the above object, the technical solution adopted by the present invention is that:
A kind of special fixing bolt, including integrally formed bolt head and screw rod, the screw rod is equipped with rotation spiral shell
Line, bolt head top cross recess, the bolt head side are equipped with the rotating hole being staggered, and the rotating hole runs through bolt
Head.
The rotation screw thread is equipped with wearing layer.
The screw rod tail is equipped with pointed nose.
In the above-mentioned technical solutions, compared with prior art, the beneficial effect reached is: the cooperation of cross recess and rotating hole
It uses, can reduce it to avoid the excessive use of cross recess and wear probability.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of the embodiment of the present invention one.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and embodiments.
Embodiment one:
As described in Figure 1, the special fixing bolt of one kind of the invention, including integrally formed bolt head 1 and screw rod 2,
The screw rod 2 is equipped with rotation screw thread 3, and the 1 top cross recess 4 of bolt head, 1 side of bolt head is equipped with and is staggered
Rotating hole 5, the rotating hole 5 run through bolt head 1.
The rotation screw thread 3 is equipped with wearing layer 6.
2 tail portion of screw rod is equipped with pointed nose 7.
In the above-mentioned technical solutions, compared with prior art, the beneficial effect reached is: cross recess 4 and rotating hole 5 are matched
It closes and uses, can reduce it to avoid the excessive use of cross recess 4 and wear probability.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention
Equivalent change or modification made by Spirit Essence, should be covered by the protection scope of the present invention.
