Abstract
The utility model discloses a waist-shaped combined stud. The waist-shaped combined stud comprises a bolt (1) and a nut (2), wherein the nut (2) is in threaded matching with the bolt (1); the bolt (1) consists of a bolt head (1.1) and a screw (1.2) which are integrally molded; the threads on the screw (1.2) are full threads; and the cross sections of the bolt head (1.1) and the nut (2) are respectively waist-shaped. The waist-shaped combined stud is characterized in that the center of the bolt (1) is provided with an axial through hole (3) with threads. The waist-shaped combined stud disclosed by the utility model has the advantages that the position of the combined part can be adjusted without need of adding an adjusting device, so that the cost is low and the structure is simple.
Description
Technical field
The utility model relates to technical field of fastening, specifically is a kind of waist shape combination double-screw bolt.
Background technique
A kind of waist shape combination double-screw bolt is arranged at present, comprise bolt and with the bolt thread nut engaged, said bolt is made up of integrated bolt head and screw rod, the cross section of said bolt head and nut is waist shape.Through this waist shape combination double-screw bolt combiner is tightened together, if also need regulate the position of combiner, then needing increases controlling device in addition, has so not only increased cost, but also makes overall structure become complicated.
The model utility content
The technical problem that the utility model will solve provides and a kind ofly can play the waist shape combination double-screw bolt that the position of fastening combiner can be conveniently regulated in fastening effect again, and simple in structure.
In order to achieve the above object; The technological scheme that the utility model provides is: a kind of waist shape combination double-screw bolt; Comprise bolt and with the bolt thread nut engaged, said bolt is made up of integrated bolt head and screw rod, the screw thread on the said screw rod is a Full Thread FT; The cross section of said bolt head and nut is waist shape, and the center of said bolt is provided with threaded axial hole.
After adopting technique scheme; The utility model compared with prior art has the following advantages: the bolt center of the utility model waist shape combination double-screw bolt is provided with threaded axial hole, and the utility model just can be used with the screw rod with the axial hole screw-thread fit like this; At first with the fastening fixed combination parts that need of the screw bolt and nut of the utility model; Then screw rod is passed threaded axial hole on the bolt, just can drive bolt through rotating screw bolt and move, and then drive whole combiner and move; Reach the function of regulating the combiner position; Do not need extra increase controlling device that the position of combiner is regulated, reduced cost, and simple in structure.
