Description
Technical field
The utility model relates to fastener areas, relates in particular to a kind of waist shape combination double-screw bolt.
Background technique
Existing technology has a kind of waist shape combination double-screw bolt; It comprises bolt and nut engaged with it, through this waist shape combination double-screw bolt combiner is tightened together, if also need adjust the position of combiner; Then needing increases controlling device in addition, has so not only increased cost and complex structure.
Summary of the invention
The utility model technical problem to be solved is: provide a kind of and can play that fastening effect can conveniently be regulated again and waist shape combination double-screw bolt simple in structure.
The technological scheme that the utility model adopted is: a kind of waist shape combination double-screw bolt; Comprise the bolt and the nut of screw-thread fit with it; Said bolt is provided with integrated bolt head and bolt shank; Said bolt head and nut inboard are equipped with pad, and the cross section of said bolt head and nut is waist shape, and described bolt axis is to also being provided with threaded through hole.
Adopt above structure compared with prior art; The utlity model has following advantage: on the bolt of combination in the double-screw bolt, axially open a screwed through hole, this sample combination just can with the screw rod that cooperates with the through hole whorl use that matches, at first with the fastening fixed combination parts that need of the bolts and nuts of this combination; Then screw rod is passed threaded through hole on the bolt; The bolt that just can drive this combination through rotating screw bolt moves, and then drives through bolt and nut fixed combination parts, has reached the function of regulating the combiner position; So just not needing to increase again controlling device just can reach regulatory function, and simple in structure.
Description of drawings
Fig. 1 is the structural representation of a kind of waist shape combination of the utility model double-screw bolt.
Fig. 2 removes the pad view of A direction afterwards for Fig. 1.
As shown in the figure: 1, bolt; 1.1, bolt head; 1.2, bolt shank; 2, nut; 3, pad; 4, through hole.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done to further describe, but the utility model is not limited only to following embodiment.
Like Fig. 1, shown in Figure 2: a kind of waist shape combination double-screw bolt; Comprise the bolt 1 and the nut 2 of screw-thread fit with it; Said bolt 1 is provided with integrated bolt head 1.1 and bolt shank 1.2; Said bolt head 1.1 is equipped with pad 3 with nut 2 inboards, and the cross section of said bolt head 1.1 and nut 2 is waist shape, and described bolt 1 axially also is provided with threaded through hole 4.Described cross section is a waist shape for waist shape is meant the cross section housing, but middle circle in addition, described bolt shank 1.2 is half screw rod, and promptly a part is threaded, and a part is a polished rod.
The use principle of a kind of waist shape combination of the utility model double-screw bolt is: at first be to need fastening combiner through bolt in this combination 1 and nut 2 lockings; Then because have threaded through hole 4 in the bolt; And be provided with a screw rod with said through hole 4 screw-thread fit; The position of so just can rotating screw bolt regulating bolt 2; And then regulate through bolt 1 and 2 fixed combination position component of nut, having reached does not increase the function that controlling device can be regulated the combiner position again, and the utility model is simple in structure.
