Description

A kind of hexagon ring cross recess tooth of synchronous belt 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 hexagon ring cross recess tooth of synchronous belt 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, there is rust corrosion, material property decline in girder, flange attachment bolt etc..When equipment carries out dismantling and keeps in repair greatly, it may appear that sliding Silk phenomenon, causes screw to disassemble, brings the biggest inconvenience, operationally equipment to the replacing of maintenance of equipment and part Vibration is more obvious, causes bolt looseness to come off, and affects the normal work of equipment, reduces the reliability of equipment, it is proposed that one Plant hexagon ring cross recess tooth of synchronous belt 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 hexagon ring cross recess band tooth Stricture of vagina bolt, the most well solves stripped thread phenomenon during demounting bolt, but also solves the bolt caused by mechanical vibration Loosen.
For achieving the above object, the utility model proposes a kind of hexagon ring cross recess tooth of synchronous belt bolt, including stud, Six prism nuts, inner hexagonal hole, cross recess, anti-skidding groove and screw thread, described stud be shaped as cylinder, described stud Upper end is smooth cylindrical, and bottom is provided with the screw thread of a length of overall length 3/5, and the top of described stud is provided with six prism nuts, The upper surface of described six prism nuts is provided with cross recess, and it is orthohexagonal that the side opening of described six prism nuts is provided with cross section Inner hexagonal hole, the distance of described two opposite side of inner hexagonal hole is the 1/3 of six prism nut stage body height, the axle of described inner hexagonal hole Line is perpendicular to six prism nuts, and described inner hexagonal hole is completely through in six prism nuts, and the lower surface of described six prism nuts sets Have anti-skidding groove, described anti-skidding groove by six prism panes along curve extension to stud, around the centrage of stud in all Even circle distribution, the cross sectional shape of described anti-skidding groove is zigzag or trapezoidal.As preferably, described anti-skidding groove cross section uses Zigzag or trapezoidal shape.
As preferably, described screw thread is triangle thread, and the lead angle of described screw thread is 4 degree.
As preferably, described a kind of hexagon ring cross recess tooth of synchronous belt bolt uses SCM435 alloy steel material, and appearance Face is electroplate with admiro.
The beneficial effects of the utility model: this utility model by having inner hexagonal hole in the side of six prism nuts, when When stripped thread phenomenon occurs in bolt, inner hexagon spanner can be inserted in the inner hexagonal hole of six prism nuts, can be by Bolt dismantling Get off, and increase anti-skidding groove in the bottom surface of six prism nuts, being fastenedly connected of workpiece can be realized, effectively solve loosening Problem, six prism nuts have cross recess, and available die nut is to its tightening and loosening, it is also possible to Phillips screwdriver realizes tight Gu dismounting, it is adapted to different operating environments.
Feature of the present utility model and advantage will combine accompanying drawing by embodiment and be described in detail.

[detailed description of the invention]
Refering to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, this utility model one hexagon ring cross recess tooth of synchronous belt bolt, including stud 1, six prism nuts 2, inner hexagonal hole 3, cross recess 4, anti-skidding groove 5 and screw thread 6, described stud 1 be shaped as cylinder, institute The upper end stating stud 1 is smooth cylindrical, and bottom is provided with the screw thread 6 of a length of overall length 3/5, and the top of described stud 1 is provided with Six prism nuts 2, the upper surface of described six prism nuts 2 is provided with cross recess 4, and the side opening of described six prism nuts 2 is provided with Cross section is orthohexagonal inner hexagonal hole 3, and the lower surface of described six prism nuts 2 is provided with anti-skidding groove 5.Described inner hexagonal hole 3 The distance of two opposite side is the 1/3 of six prism nut 2 stage body height, and the axis of described inner hexagonal hole 3 is perpendicular to six prism nuts 2, described inner hexagonal hole 3 is completely through in six prism nuts 2.Described anti-skidding groove 5 by six prism nut 2 sides along curve extension To stud 1, the centrage around stud 1 is uniform circular distribution, and the cross sectional shape of described anti-skidding groove 5 is zigzag or ladder Shape.Described screw thread 6 is triangle thread, and the lead angle of described screw thread 6 is 4 degree.Described a kind of hexagon ring cross recess band tooth Stricture of vagina bolt uses SCM435 alloy steel material, and outer surface is electroplate with admiro.
Utility model works process:
Bolt in the course of the work, during installation, is penetrated by this utility model one hexagon ring cross recess tooth of synchronous belt bolt In the hole of connected workpiece, according to the restriction of working place, it is carried out by corresponding selection die nut or Phillips screwdriver Fastening.During demounting bolt, first-selected die nut, when bolt stripped thread, by setting up inner hexagonal hole 3 in six prism nut 2 sides, Make die nut may be inserted in inner hexagonal hole 3, and complete dismantlement work, by setting up anti-slop serrations in six prism nut 2 bottoms Stricture of vagina 5, limits workpiece slip relative with bolt.This utility model can effectively solve plant equipment bolt stripped thread problem and ask with loosening Topic, when decreasing dismounting due to stripped thread to the destruction of mechanical workpieces, avoid equipment work time the loosening, for efficiently installing of bolt Basis has been laid in the normal work of demounting bolt and equipment.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any new to this practicality Scheme after type simple transformation belongs to protection domain of the present utility model.
