Description

A kind of anti-loosening bolt
[technical field]
This utility model relates to outdoor machinery, mining machinery, the technical field of chemical industry equipment part connection fastening, particularly A kind of technical field of anti-loosening bolt.
[background technology]
Other medium-sized plant equipment such as lorry, machine for unloading coal, long-term wind and weather Exposure to Sunlight, easily make to expose spiral shell on equipment Bolt, the generation rust corrosion such as girder, flange attachment bolt, material property declines, and bolt is the fastening connection piece that people are the most frequently used, it Simple in construction, easy to use, respond well, it is widely used in various occasion.But, in some occasions that there are vibrations, it is used for The bolt of fastening often loosens, and causes connection to disengage, and machine failure even causes security incident, and manufacturing for this can be effective Anti-loosening bolt becomes extremely urgent, and present bolt is essentially all is fixed connection by sheathed screw rod, it is possible to According to the different adjustment degree of tightness of fixing connector thickness, it is proposed that a kind of anti-loosening bolt.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, it is proposed that a kind of anti-loosening bolt, well Solve the bolt looseness that the extrinsic factor such as vibrations cause, it is ensured that bolted steadiness.
For achieving the above object, the utility model proposes a kind of anti-loosening bolt, including nut, stud, screw thread, hexagonal Groove, fastening stud, screwed hole and fastening part, described stud be shaped as cylinder, described stud outside be provided with screw thread, The top of described stud is provided with nut, described nut be shaped as six prisms, described nut upper surface is provided with hexagonal groove, described It is provided with screwed hole below hexagonal groove, is provided with fastening stud in described screwed hole, below described fastening stud, fastening part is installed, The bottom of described nut offers several circular holes.
As preferably, described fastening part is provided with driving plate body, described driving plate body generally circular in shape, described driving plate Be distributed on body several fastening post, described fastening post is uniformly distributed ringwise, and described fastening post matches with circular hole, described tightly Gu post includes cylindrical bar and frustum.
As preferably, the axis of described screwed hole coincides with the axis of stud, and the length in the aperture of described screwed hole is little Length in the spacing of hexagonal groove two opposite side.
As preferably, described hexagonal groove be shaped as regular hexagon, the center of described hexagonal groove and the axis of stud Overlapping, the degree of depth of described hexagonal groove is equal to the 1/2 of nut stage body height.
As preferably, the center of described fastening stud and the dead in line of stud, described fastening stud upper surface is provided with ten Word groove.
The beneficial effects of the utility model: this utility model by having hexagonal groove and fastening spiral shell in the inside of nut Post, it is possible to after bolt is screwed in screw, by coordinating of fastening stud and fastening part, fastening post contacts with connector surface, Increasing friction force, it is to avoid loosening easily of bolt, it is ensured that bolted steadiness.
Feature of the present utility model and advantage will combine accompanying drawing by embodiment and be described in detail.
