Abstract
The utility model relates to a withdrawal-stopping screw bolt. An inner-circular through hole (4) arranged on the center of the screw bolt (1) penetrates from the tail (3) of the screw bolt and the head (2) of the screw bolt; a conical stud (6) is arranged in the inner-circular through hole (4) of the screw bolt (1), and an adjusting nut (8) is arranged on the conical stud (6); the tail (3) of the screw bolt is provided with symmetrical nicks. The utility model has the advantages of simple structure, reliable fixing and convenient disassembly and assembly.
Description
The utility model relates to a kind of bolt, especially relates to a kind of expansion retaining bolt.
At present, people are when connecting fastening various device, member, and employed bolt mostly can not retaining, and in the equipment operation process, because bolt loosening or come off tends to cause device damage, the normal work of influence is produced.For addressing this problem, Chinese patent " a kind of recessed cap locking nut " (CN2411376Y) in, but a kind of bolt of retaining was once disclosed, this model utility is made up of bolt body, nut and recessed cap, spring washer and Screw.Simple in structure, difficult loosening advantage that this model utility has.But this model utility also comes with some shortcomings, as the element of installation space that need be connected and fixed sometimes hour, when nut, recessed cap after bolt tail screws, tend to occur be inserted into the bolt tail inner bolt hole can't be between the member less space of Screw.In addition, this model utility is when being the internal thread screw in the face of the element of installation that need be connected and fixed, and is often powerless.
The purpose of this utility model provides a kind of expansion retaining bolt that has wide range of applications, it can be fit to general fastening demand generally, can in the small range of the required connection part of element of installation space, use again, can also in the internal thread screw of the required element of installation that is connected and fixed (one of them conjugant is the internal thread screw), use.
For achieving the above object, the technical solution of the utility model is: this retaining bolt is made up of bolt body, taper double-screw bolt and adjustment nut; It is characterized in that: be drilled with interior round tube hole at the bolt center,, in the interior round tube hole of bolt, be provided with a taper double-screw bolt, on the taper double-screw bolt, be provided with the adjustment nut, be provided with symmetric windows at bolt tail through bolt tail and bolt head.
Because the utility model retaining bolt is to have adopted a kind of expansion retaining principle, compared with prior art it has fixedly, is difficult for looseningly, is convenient to installation and removal, the advantage that Applicable scope is extensive.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model.
Mode of execution: the structure of the utility model retaining bolt is made of bolt body, taper double-screw bolt and adjustment nut as shown in drawings.The bolt body center is drilled with interior round tube hole 4, and until bolt head 2, internal diameter of round tube hole 4 is slightly larger than the external diameter of taper double-screw bolt 6 in this from bolt tail 3, is beneficial to interspersed taper double-screw bolt 6; Be cut with one section symmetric windows 5 at bolt tail 3, this symmetric windows 5 is beneficial to taper double-screw bolt head 7 bolt tail 3 is expanded; Described taper double-screw bolt 6, its main body are that an end is the double-screw bolt of circular cone major part; Taper double-screw bolt 6 from bolt tail 3 insertions, until passing bolt head 2, is screwed an adjustment nut 8 then and just constituted the utility model retaining bolt on taper double-screw bolt 6.Described adjustment nut 8 through adjusting taper double-screw bolt head 7 is expanded bolt tail 3, thereby the outside thread that reaches bolt tail 3 presses, and reaches bolt and is difficult for loosening purpose with member internal thread or nut (not shown) internal thread.
Claims (5)
1, a kind of retaining bolt is characterized in that: be provided with interior round tube hole (4) at bolt (1) center, run through bolt tail (3) and bolt head (2); In interior round tube hole (4), be provided with a taper double-screw bolt (6), on taper double-screw bolt (6), be provided with and adjust nut (8), be provided with symmetric windows (5) at bolt tail (3).
2, retaining bolt according to claim 1 is characterized in that: round tube hole (4) in described is for interspersed taper double-screw bolt (6), and the interior round tube hole (4) that runs through bolt tail (3) and bolt head (2) that gets out at bolt (1) center; Described taper double-screw bolt (6) passes round tube hole (4) in this.
3, want 1 described retaining bolt according to right, it is characterized in that: described symmetric windows (5) is the breach in one section symmetry of bolt tail (3) cutting; Described breach is beneficial to taper double-screw bolt head (7) bolt tail (3) is expanded.
4, according to claim 1 or the described retaining bolt of claim 2, it is characterized in that: described taper double-screw bolt (6), its main body are that an end is the double-screw bolt of circular cone major part.
5, retaining bolt according to claim 1 is characterized in that: described adjustment nut (8) is the nut that is screwed on the taper double-screw bolt (6); Described nut can make taper double-screw bolt head (7) that bolt tail (3) is expanded through adjusting, thus reach with fastening piece press can retaining purpose.
