Abstract
The utility model relates to an automobile wheel rotation preventing bolt and aims at providing a wheel rotation preventing bolt which is better in rotation prevention effect. The wheel rotation preventing bolt comprises a bolt head and a threaded rod and is characterized in that the end face of the bolt head is composed of a semi-circular end face and an isosceles trapezoid end face, the upper edge of the isosceles trapezoid end face is smaller than the lower edge of the isosceles trapezoid end face in length, the lower edge is the cutting edge of the bolt head, two waist edges of the isosceles trapezoid end face are respectively tangent with the circular arc tail ends of the semi-circular end face. Preferably, included angles formed by the two waist edges and the lower edge of the isosceles trapezoid end face are 90 degrees, and the lower edge is an arc line which dents inward toward the upper edge. Due to the fact that one part of the end portion of the bolt is in an isosceles trapezoid structure, and the lower edge is the arc line which dents inward, the bolt is enabled to be tightly connected with a combining face and can not rotate so that the purpose of rotation prevention is achieved.
Description
Technical field
The utility model relates to a kind of bolt, relates in particular to a kind of anti-turn bolt that is applied on the automotive wheel.
Background technique
At present, the wheel bolt on the market all is the edging snap bolt, and as shown in Figure 1, bolt head is round end, has the function of certain anti-rotation on the round end with cut edge (or claiming seam), but effect or bad, bolt rotates and also happens occasionally, and affects quality of product.
The model utility content
For the deficiencies in the prior art, the utility model aims to provide a kind of wheel anti-turn bolt of anti-rotation better effects if.
In order to address the above problem, the utility model provides a kind of wheel anti-turn bolt, comprise bolt head and screw rod, this wheel anti-turn bolt is characterised in that: the end face of bolt head is combined by semicircle end face and isosceles trapezoid end face, wherein the upper base edge lengths of isosceles trapezoid end face is less than the length of bottom, the bottom is the side cut of bolt head, and two waists of the trapezoidal end face of these isosceles are tangent with the circular arc end of semicircle end face respectively.
Preferably, the angle of two waists of described isosceles trapezoid end face and bottom is 90 °.
More preferably, described bottom is the camber line to described upper base indent.
The beneficial effects of the utility model are: because a bolt end part adopted isosceles trapezoidal structure, the bottom is the camber line of indent, connects so that bolt is connected with junction plane, can't rotate, thereby reach the purpose of anti-rotation.
Description of drawings
Fig. 1 is the structural representation of the end face of existing wheel bolt head;
Fig. 2 is the structural representation of the end face of wheel bolt head of the present utility model.
Embodiment
Below in conjunction with accompanying drawing to this practical being described further.
Shown in Figure 2, a kind of wheel anti-turn bolt of the present utility model, comprise bolt head and screw rod (not looking among the figure), the end face of bolt head is combined by the end face that end face and the end face of end face semicircular in shape is isosceles trapezoid, concrete, the upper base edge lengths of isosceles trapezoid end face is less than the length of bottom, the bottom is the side cut of bolt head, the trapezoidal upper base of these isosceles is connected with semicircle end face bottom, namely, two waists of the trapezoidal end face of these isosceles are tangent with the circular arc end of semicircle end face respectively, and the side cut of bolt head and semicircular fillet become lineal shape by existing arc.Two waists of described isosceles trapezoid end face and the angle α of bottom are 90 °, and namely these isosceles are trapezoidal is roughly a rectangle.Described bottom is the camber line to described upper base indent, conveniently cooperates with surface of contact.Because a bolt end part adopted isosceles trapezoidal structure, so that being connected with junction plane, bolt connects, can't rotate, thereby reach the purpose of anti-rotation.
Claims (3)
1. wheel anti-turn bolt, comprise bolt head and screw rod, this wheel anti-turn bolt is characterised in that: the end face of bolt head is combined by semicircle end face and isosceles trapezoid end face, wherein the upper base edge lengths of isosceles trapezoid end face is less than the length of bottom, the bottom is the side cut of bolt head, and two waists of the trapezoidal end face of these isosceles are tangent with the circular arc end of semicircle end face respectively.
2. wheel anti-turn bolt according to claim 1, it is characterized in that: two waists of described isosceles trapezoid end face and the angle of bottom are 90 °.
