Abstract
The utility model discloses a pentagonal combined stud, which comprises a bolt (1) and a nut (2) in threaded fit with the bolt (1), wherein the bolt (1) consists of a bolt head (1.1) and a screw rod (1.2) which are integrally formed; and a thread on the screw rod (1.2) is a full thread, and the cross section of the bolt head (1.1) and the cross section of the nut (2) are respectively pentagonal. The pentagonal combined stud is characterized in that the center of the bolt (1) is provided with an axial through hole (3) with a thread. According to the triangular combined stud disclosed by the utility model, the position of the combined part can be adjusted without the need of additionally arranging an adjusting device; and the triangular combined stud disclosed by the utility model is low in cost and simple in structure.
Description
Technical field
The utility model relates to technical field of fastening, specifically is a kind of five jiaos of combination double-screw bolts.
Background technique
Have at present a kind of five jiaos the combination double-screw bolts, 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 pentagon.Through this five jiaos of combination double-screw bolts 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 five jiaos of the position combination double-screw bolts that 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 five jiaos of combination double-screw bolts; 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 pentagon, 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 five jiaos of combinations of the utility model 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.
Description of drawings
Fig. 1 is the structural representation (half sectional view) of five jiaos of combinations of the utility model double-screw bolt.
Fig. 2 is the schematic top plan view of the bolt of five jiaos of combinations of the utility model double-screw bolt.
As shown in the figure: 1, bolt 1.1, bolt head 1.2, screw rod 2, nut 3, axial hole.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further explain.
Like Fig. 1, shown in Figure 2: a kind of five jiaos of combination double-screw bolts; Comprise bolt 1 and with the nut 2 of bolt 1 screw-thread fit; Said bolt 1 is made up of with screw rod 1.2 integrated bolt head 1.1, and the screw thread on the said screw rod 1.2 is a Full Thread FT, all is threaded on the outer peripheral surface of promptly whole screw rod 1.2.The cross section of said bolt head 1.1 and nut 2 is pentagon, and five angles are promptly arranged, and the center of said bolt 1 is provided with threaded axial hole 3, and axial hole 3 is meant the hole of through bolt upper and lower end face here.Said cross section is that pentagon is meant that the profile of cross section is a pentagon, middle circle expression axial hole 3.
The utility model cooperates screw rod to use in use, and screw rod and axial hole 3 are spirally connected, and it is mobile vertically that rotating screw bolt can make five jiaos of combination double-screw bolts like this, also just drive its fastening device mobile vertically.
Claims (1)
1. one kind five jiaos are made up double-screw bolts; Comprise bolt (1) and with the nut (2) of bolt (1) screw-thread fit; Said bolt (1) is made up of integrated bolt head (1.1) and screw rod (1.2); Screw thread on the said screw rod (1.2) is a Full Thread FT, and the cross section of said bolt head (1.1) and nut (2) is pentagon, it is characterized in that: the center of said bolt (1) is provided with threaded axial hole (3).
