Abstract
The present invention relates to a kind of special primary and secondary bolts, including external screw rod ontology, inner screw ontology is equipped in the external screw rod ontology, the external screw rod ontology is externally provided with rotation screw thread, it is connected through a screw thread between the inner screw ontology and external screw rod ontology, the external screw rod bodies top has been equipped with spiral shell component, and the inner screw bodies top has passed through spiral shell component and has been connected with upper cap nut.Advantage is: the preparation of primary and secondary bolt, can play few purpose for preparing bolt.
Description
Technical field
The present invention relates to concrete construction technical fields, more particularly to a kind of special primary and secondary 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.But in existing bolt, each bolt is all only individual bolt
It uses, when the bolt of needs is more, needs to prepare a lot of bolts just with spare.
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 primary and secondary bolts.
To achieve the above object, the technical solution adopted by the present invention is that:
A kind of special primary and secondary bolt, including external screw rod ontology, the external screw rod ontology is interior equipped with inner screw ontology, described
External screw rod ontology is externally provided with rotation screw thread, is connected through a screw thread between the inner screw ontology and external screw rod ontology, the outer spiral shell
It is equipped with spiral shell component at the top of bar body, the inner screw bodies top has passed through spiral shell component and has been connected with upper cap nut.
Described spiral shell component is ring nut, and the tail end in described spiral shell portion is equipped with insertion part.
Knob is equipped in the upper cap nut.
The inner screw body bottom portion connects pointed nose.
In the above-mentioned technical solutions, compared with prior art, the beneficial effect reached is: the preparation of primary and secondary bolt can rise
To few purpose for preparing bolt.
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 primary and secondary bolt of one kind of the invention, including external screw rod ontology 1, the external screw rod ontology 1
Interior to be equipped with inner screw ontology 2, the external screw rod ontology 1 is externally provided with rotation screw thread 3, the inner screw ontology 2 and external screw rod ontology 1
Between connected by screw thread 4, spiral shell component 5 has been equipped at the top of the external screw rod ontology 1, has been passed through at the top of the inner screw ontology 2
Spiral shell component 5 is simultaneously connected with upper cap nut 6, and the top of inner screw ontology 2 passes through external screw rod ontology 1, convenient for rising for inner screw ontology 2
Out.
Described spiral shell component 5 is ring nut, and the tail end in described spiral shell portion is equipped with insertion part 7, the setting of insertion part 7, just
It is opened in the rotation of external screw rod ontology 1.
Knob 8 is equipped in the upper cap nut 6, convenient for inner screw ontology 2 from external screw rod ontology 1 out.
2 bottom of inner screw ontology connects pointed nose 9, convenient for the use of inner screw ontology 2.
In the above-mentioned technical solutions, compared with prior art, the beneficial effect reached is: the preparation of primary and secondary bolt can rise
To few purpose for preparing bolt.
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.
