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.
