The bolt is provided with the bolt hollow hole along the axial lead direction, the bolt hollow hole penetrates through the bolt longitudinally, the part of the bolt with the bolt screw teeth is divided into four sections along the cross cutting line by taking the axial lead as the center, the nut is screwed on the bolt, the gasket is sleeved on the bolt, and the wedge corresponds to the bolt hollow hole.
Description
Technical Field
The utility model relates to a fastener technical field specifically is a can solve not hard up bolt assembly of not hard up problem.
Background
At present, bolts are widely applied to various industries, and the bolts have the problem of looseness in use and can cause immeasurable loss. The existing non-loose bolt technology mainly adopts the technical proposal that the nut and the washer are provided with a cotter pin and the like, which can not realize the non-loose in the real sense and are inconvenient to disassemble once being installed.
SUMMERY OF THE UTILITY MODEL
The technique that exists is not enough to the aforesaid, the utility model aims at providing not hard up bolt assembly, it can realize not hard up, and convenient to detach.
In order to solve the technical problem, the utility model adopts the following technical scheme:
the bolt assembly is characterized by comprising a wedge, a nut, a washer, a bolt hollow hole, a cross cutting line, bolt screw teeth and a bolt, wherein the bolt hollow hole is formed in the bolt along the axial lead direction, the bolt hollow hole penetrates through the bolt longitudinally, the part of the bolt with the bolt screw teeth is divided into four petals along the cross cutting line by taking the axial lead as the center, the nut is arranged on the bolt in a threaded manner, the washer is sleeved on the bolt, and the wedge corresponds to the bolt hollow hole.
Preferably, the diameter of the wedge increases gradually from one end to the other end.
Preferably, the length of the wedge is 0.8 times of the length of the bolt thread, the diameter of one end of the wedge is 0.9 times of the aperture of the hollow hole of the bolt, and the diameter of the other end of the wedge is 1.3 times of the aperture of the hollow hole of the bolt.
The beneficial effects of the utility model reside in that: the bolt can be prevented from loosening, and the bolt is convenient to detach after being installed. Simple structure can reform transform current ordinary bolt, then cooperates a wedge can form not hard up bolt assembly, and the cost is lower.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a three-dimensional exploded view of the non-loose bolt assembly of the present invention;
FIG. 2 is a schematic structural view of a cross-shaped cutting line of the non-loose bolt assembly of the present invention;
description of reference numerals:
the bolt comprises a wedge 1, a nut 2, a washer 3, a bolt hollow hole 4, a cross cutting line 5, bolt threads 6 and a bolt 7.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-2, the bolt assembly without loosening comprises a wedge 1, a nut 2, a washer 3, a bolt hollow hole 4, a cross cutting line 5, a bolt thread 6 and a bolt 7, wherein the bolt 7 is provided with the bolt hollow hole 4 along the axial lead direction, the bolt hollow hole 4 longitudinally penetrates through the bolt 7, the part of the bolt 7 with the bolt thread 6 is divided into four pieces along the cross cutting line 5 by taking the axial lead as the center, the nut 2 is arranged on the bolt 7 in a threaded manner, the washer 3 is sleeved on the bolt 7, and the wedge 1 corresponds to the bolt hollow hole 4.
Further, the diameter of the wedge 1 is gradually increased from one end to the other end.
Further, the length of the wedge 1 is 0.8 times of the length of the bolt thread 6, the diameter of one end of the wedge 1 is 0.9 times of the aperture of the bolt hollow hole 4, and the diameter of the other end of the wedge 1 is 1.3 times of the aperture of the bolt hollow hole 4.
When the bolt is used, the bolt 7 is installed on a using part, the washer 3 and the nut 2 are sleeved on the bolt, the nut 2 is screwed, and the fastening degree needs to reach a required value of a user. And then the wedge 1 is driven into the bolt hollow hole 4 at the tail end of the bolt thread 6 until the bolt thread 6 expands and deforms along the four divided petals of the cross-shaped cutting line and the wedge 1 is clamped. Finally, cutting off the rest part of the exposed bolt thread 6 of the wedge 1;
when the bolt is disassembled, a punch with the inner diameter smaller than that of the hollow hole 4 of the bolt is adopted to punch the wedge 1 from the head of the bolt 7 to the direction of the bolt thread 6, then the expansion part of the bolt thread 6 is restored by a hydraulic sleeve, finally the nut 2 is disassembled, and the bolt 7 is pulled out, thus completing the disassembly.
The wedge 1 can be machined by a lathe by using Q235A round steel. The existing ordinary bolt 7 can be modified by utilizing the existing mature metal drilling and cutting technology to be modified into the bolt 7 which does not loosen.
The utility model discloses a design can realize that bolt 7 is not hard up, and installation back convenient to detach. Simple structure can reform transform current ordinary bolt 7, then cooperates a wedge 1 and can form not hard up bolt 7 subassembly, and the cost is lower.
It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
