[background technology]
Other medium-sized plant equipment such as lorry, machine for unloading coal, long-term wind and weather Exposure to Sunlight, easily make the exerted bolt on equipment, there is rust corrosion in girder, flange attachment bolt etc., material property declines.When equipment carries out dismantling and keeps in repair greatly, there will be stripped thread phenomenon, screw is caused to disassemble, the biggest inconvenience is brought to the replacing of maintenance of equipment and part, operationally vibration equipment is more obvious, causes bolt looseness to come off, and affects the normal work of equipment, reduce the reliability of equipment, it is proposed that a kind of hexagon ring cross recess tooth of synchronous belt bolt.
[summary of the invention]
The purpose of the present invention solves the problems of the prior art exactly, it is proposed that a kind of hexagon ring cross recess tooth of synchronous belt bolt, the most well solves stripped thread phenomenon during demounting bolt, but also solves the bolt looseness caused by mechanical oscillation.
For achieving the above object, the present invention 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, the upper end of described stud is smooth cylindrical, bottom is provided with the screw thread of a length of overall length 3/5, the top of described stud is provided with six prism nuts, the upper surface of described six prism nuts is provided with cross recess, it is orthohexagonal inner hexagonal hole that the side opening of described six prism nuts is provided with cross section, the lower surface of described six prism nuts is provided with anti-skidding groove.
As preferably, the distance of described two opposite side of inner hexagonal hole is the 1/3 of six prism nut stage body height, and the axis of described inner hexagonal hole is perpendicular to six prism nuts, and described inner hexagonal hole is completely through in six prism nuts.
As preferably, described anti-skidding groove is extended to stud by six prism panes along curve, and the center line around stud is uniform circular distribution, and 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 outer surface is electroplate with admiro.
Beneficial effects of the present invention: the present invention is by having inner hexagonal hole in the side of six prism nuts, when there is stripped thread phenomenon in bolt, inner hexagon spanner can be inserted in the inner hexagonal hole of six prism nuts, Bolt dismantling can be got off, and anti-skidding groove is increased in the bottom surface of six prism nuts, being fastenedly connected of workpiece can be realized, effectively solve loosening problem, cross recess is had on six prism nuts, available die nut is to its tightening and loosening, also can realize tightening and loosening with Phillips screwdriver, be adapted to different operating environments.
Inventive feature and advantage will combine accompanying drawing by embodiment and be described in detail.
