Utility model content
The purpose of this utility model is to provide a kind of end plate bolt of high tautness, can improve prior art and existProblem, be provided with the screw thread cylinder of perpendicular grooves by employing, in the time that bolt is selected in nut, vertically recessedGroove, under the interaction force of nut and bolt, produces axial deformation, and the screw thread cylinder of the bolt that is is subject to radiallyShearing force, thereby make between bolts and nuts in being subject to the relative friction forces of screw thread, be subject to verticalThe torsion that groove variations is brought, thus the tautness that is is higher, is not easy to come off.
The utility model is achieved through the following technical solutions:
An end plate bolt for high tautness, comprises bolt body and is arranged on the hexagonal nail of bolt body one sideHead, described bolt body is polished rod cylinder, establishes away from described hexagonal ailhead one end at described bolt bodyBe equipped with screw thread cylinder, on described screw thread cylinder, be provided with perpendicular grooves, the degree of depth side of described perpendicular groovesTo being parallel to described bolt body radially, described in the minimum extension diameter of described hexagonal ailhead is more than or equal toThe external diameter of bolt body, the external diameter of described screw thread cylinder equals the external diameter of described bolt body.
Further, for realizing better the utility model, described perpendicular grooves be disposed on describedOn screw thread cylinder 2, the perpendicular grooves described in 2 staggers mutually along the axis direction of described screw thread cylinderArrange.
Further, for realizing better the utility model, not phase of the longitudinal projection of the perpendicular grooves described in 2Mutual respect is closed.
Further, for realizing better the utility model, at described bolt body and described hexagonal ailheadBetween be provided with spacing collar, the external diameter of described spacing collar is greater than the external diameter of described bolt body, described limitThe external diameter of position circle is greater than the maximum extension diameter of described hexagonal ailhead.
Further, for realizing better the utility model, the maximum extension diameter of described hexagonal ailhead equalsThe external diameter of described bolt body, arranges near described hexagonal ailhead one end outer wall at described bolt bodyHave external screw thread, this externally threaded length equals the width of described spacing collar, at described bolt body near instituteHexagonal ailhead one end of stating is provided with detent, the plane parallel at the depth direction place of described detentIn described bolt body radially, on the inwall of described spacing collar, be provided with internal thread, described is spacingCircle is threaded on described bolt body.
The utility model compared with prior art, has following beneficial effect:
(1) the utility model is by adopting the mode that perpendicular grooves is set on screw thread cylinder, the threaded post that isWhen face and nut are in contact with one another, perpendicular grooves produces distortion under nut relativity, and screw thread cylinder is subject toThe torsion of nut to its generation, thus radial effect power produced, make screw thread cylinder in connection procedure, be subject to simultaneouslyTo axial frictional force and torsion radially, thereby be not easy to come off, tautness is higher;
(2) the utility model is identical with the external diameter of bolt body by screw thread cylinder by adopting, and can conveniently existCutting thread on bolt body, convenient processing and operation.

Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail, but reality of the present utility modelThe mode of executing is not limited to this.
Embodiment 1:
As shown in Figure 1, a kind of end plate bolt of high tautness, comprises bolt body 101 and is arranged on bolt originallyThe hexagonal ailhead 102 of body 101 1 sides, described bolt body 101 is polished rod cylinder, at described bolt originallyBody 101 is provided with screw thread cylinder 103 away from described hexagonal ailhead 102 one end, at described screw thread cylinder 103On be provided with perpendicular grooves 104, the depth direction of described perpendicular grooves 104 is parallel to described bolt body101 radially, and the minimum extension diameter of described hexagonal ailhead 102 is more than or equal to described bolt body 101External diameter, the external diameter of described screw thread cylinder 103 equals the external diameter of described bolt body 101.
Embodiment 2:
The present embodiment is on the basis of embodiment 1, for fear of due to perpendicular grooves being set, screw thread cylinder being existedWhile being subject to radial effect power, cause the fracture of screw thread cylinder, in the present embodiment, preferably, described perpendicular grooves104 for being disposed on 2 on described screw thread cylinder 103, and the perpendicular grooves 104 described in 2 is along instituteThe setting of mutually staggering of the axis direction of the screw thread cylinder 103 of stating.
