Description
Technical field
The present invention relates to Hardware fitting field, and in particular to a kind of assembling bolt.
Background technology
Bolt screw is the accessory commonly used in life, in fields such as automobile, ship, aircraft, buildings using very
Extensively, existing bolt is generally made up of nut and bolt body.What length was usually fixed, such bolt
The application of most of occasion can be met, but in some occasions, for example, need a number of stay bolt and certain
The lag bolt of quantity, if having lacked one or two stay bolt or lag bolt temporarily, also needs to deallocation, causes work
Greatly increase as amount, can solve the above problems if the length of bolt can arbitrarily switch.
The content of the invention
Goal of the invention：It is contemplated that overcoming the defect of prior art, there is provided a kind of variable assembling bolt of length.
Technical scheme：A kind of assembling bolt, including kingbolt, the nuts on kingbolt, secondary bolt,
The kingbolt lower end has connecting portion, and the connecting portion is provided with lateral through hole；The secondary bolt upper end is provided with
The first blind hole engaged with connecting portion, the secondary bolt is provided with the second lateral blind hole, and the assembling bolt is also wrapped
Screw division is included, the screw division is arranged in connection kingbolt and secondary bolt in the through hole and the second blind hole.
Further, the nut is provided with cross recess.
Further, the nut is provided with a word groove.
Further, the deep equality of the length of the connecting portion and the first blind hole.
Further, the length of the connecting portion in kingbolt overall length 1/3rd between a quarter.
Beneficial effect：The assembling bolt length of the present invention is variable, directly can be made using kingbolt as lag bolt
With, it is also possible to kingbolt and secondary bolt are coordinated and is used as stay bolt.Even if in some cases, being badly in need of one
A little stay bolts or lag bolt, it is also possible to the requirement for using is met using the assembling bolt.
Description of the drawings
Fig. 1 is assembling bolt schematic diagram；
Fig. 2 is assembling bolt generalized section；
Fig. 3 is schematic diagram at major-minor bolt connection.
Specific embodiment
As Figure 1-3, a kind of assembling bolt, including kingbolt 2, the nuts 1 on kingbolt,
