Description
Technical field
The present invention relates to tyre technologies, more particularly to a kind of tire and its anti-skid stud.
Background technique
Anti-skid stud is inlayed on tire, can promote road holding of the tire on ice and snow road.Anti-skid stud include nail body and
The blind rivet to connect together with nail body, in application, nail body is embedded in tire tread, blind rivet is exposed at outside tire tread.The material of general nail body
Matter is all that cost is relatively low aluminium.
Existing anti-skid stud, the nail body of anti-skid stud can be seriously worn after a period of use, after nail body is seriously worn, be prevented
The stable connection of sliding nail and rubber for tire is deteriorated, and leading to tire, road holding is deteriorated when in use, it is more serious will lead to it is anti-skidding
Nail directly falls off.
In view of this, how to prevent the abrasion of anti-skid stud nail body to promote the road holding and stability of anti-skid stud is ability
Field technique personnel's technical issues that need to address.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of anti-skid stud of tire, including for being embedded in tire tread

Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, with reference to the accompanying drawing and have
Body embodiment is described in further detail technical solution of the present invention.
As shown in Figure 1, the anti-skid stud of the tire includes blind rivet 1 and nail body 2, as shown in Fig. 2, in application, blind rivet 1 is exposed at wheel
Outside tire tread, nail body 2 is embedded in tire tread.
As shown in Figure 1, nail body 2 is successively arranged nail body head 21, nail body neck 22 and nail body pedestal 23 along axial direction.Follow closely body
Head 21 has the first segment body 211 and the second segment body 212, and blind rivet is set to the top surface of the first segment body 211, and the second segment body 212 is set to
The bottom surface of first segment body 211.Second segment body 212 is projected as two sides and top margin on the plane Q for being parallel to anti-skid stud axis
Trapezoidal (understanding in conjunction with Fig. 6 and Fig. 7) in obtuse angle.More specifically, the outer peripheral surface of the second segment body 212 is to push up the big rotary table of handle
Face.
As shown in figure 8, when wheel on rough road surface (asphalt road, cement road, small gravel road etc.) when driving, prevent
When the blind rivet 1 of sliding nail and road surface contact, the nail body 2 of anti-skid stud can be separated close to the top on road surface with rubber for tire, and conventional is anti-
The nail of sliding nail is worn in that at this moment can contact generation with road surface.The anti-skid stud of this programme, by by the outer peripheral surface of the second segment body 212
Be set as the big round table surface of top handle, it is ensured that the top of nail body 2 separated with rubber after still by rubber bag round, without
It is exposed and is in contact with road surface, thus, it is possible to which anti-non-magnetic shim body 2 is caused to follow closely contact of the body 2 with rubber for tire by road wear
Face reduces the problem of causing anti-skid stud road holding to be deteriorated and fall off, and is able to ascend the stable connection of anti-skid stud and tire and prevents
Sliding nail road holding, so that the road holding of tire entirety be enable to be promoted.
As shown in Figure 1, the outer peripheral surface of the bottom surface on nail body head 21, the top surface for following closely body pedestal 23 and nail body neck 22 is common
It is enclosed annular groove 24.It can make to follow closely body 22 in this way and tire forms clamping structure, can further promote anti-skid stud and tire
Stable connection.
As shown in Figure 1, the outer peripheral surface of the first segment body 211 is cylindrical surface, such rubber for tire can follow closely body 2 with tight
Top, so as to further promote the stable connection of anti-skid stud and tire.
As shown in figures 1 and 3, one end end face of the blind rivet 1 far from nail body 2 is spherical surface 11, by setting spherical surface 11, makes blind rivet
1 can contact road surface in tangent mode so as to mitigate the abrasion of anti-skid stud road pavement.
Shown in as shown in Figure 1, Figure 3 and Figure 4, the outer peripheral surface of blind rivet 1 is multi-prismatic surface, makes the sideline 111 of spherical surface 11 by a plurality of line
Section is connected in turn and the junction of each line segment is respectively formed wedge angle.After the spherical surface 11 of anti-skid stud is broken into ice face, spherical surface 11
Sideline 111 can be contacted with ice sheet, play the role of ice-breaking, in this way, the ice-breaking effect of blind rivet 1 is able to ascend, so as to mention
Rise the road holding of anti-skid stud.
As shown in figure 4, in a plurality of line segment, projection line and one of the part line segment on the plane P perpendicular to anti-skid stud axis
Two long sides of rectangle S are overlapped, and projection line of the part line segment on plane P is overlapped with two short sides of rectangle S, remaining line segment is in plane
Projection line on P is located in rectangle S.
As shown in Figure 3 and Figure 4, when installation, the long side that should ensure that rectangle S is parallel with the axis of tire, that is to say, that with square
The line segment that the long side of shape S is overlapped is parallel with the axis of tire.In this way, being conducive to promote the ice-breaking effect of blind rivet 1.
As shown in Figure 1, nail body head 21 also has third segment body 213, the outer peripheral surface and nail body pedestal of third segment body 213
23 top peripheral face is multi-prismatic surface.Wherein, there are two the first plane 2131 and two for the outer peripheral surface tool of third segment body 213
Recessed area 2132 in first, two first planes 2131 to centerline parallel and are located at the width of rectangle S with the width of rectangle S
To center line two sides, recessed area 2132 is located at the length of rectangle S to center line two sides in two first.Wherein, the top of body pedestal 23 is followed closely
Portion's outer peripheral surface tool there are two recessed area 232 in the second plane 231 and two second, two second planes 231 with the width of rectangle S to
Centerline parallel and be located at the width of rectangle S to center line two sides, in two second recessed area 232 be located at the length of rectangle S to
Center line two sides.In this way, may insure 1 direction of blind rivet of anti-skid stud in use process always with initial installation direction one
It causes, to make blind rivet 1 always in optimum Working.
As shown in Figure 1, nail body head 21 also has the 4th segment body 214, the 4th segment body 214 is located at the bottom of third segment body 213
Between face and the top surface for following closely body neck 22.4th segment body 214 is projected as at an acute angle trapezoidal of two sides and top margin on plane Q
(understanding in conjunction with Fig. 6 and Fig. 7), more specifically, the outer peripheral surface of the 4th segment body 214 is to push up the small round table surface of outsole.Follow closely body pedestal
23 bottom is projected as two sides trapezoidal (understanding in conjunction with Fig. 6 and Fig. 7) at an acute angle with top margin on plane Q.Follow closely body neck
22 outer peripheral surface is cylindrical surface.In this way, the contact surface quantity and contact area of nail body 2 and rubber for tire can be increased, benefit
In further promotion anti-skid stud and tire stable connection.
Preferably, as shown in figure 5, third segment body 213 is on the perspective plane on plane P and follows closely body pedestal 23 on plane P
Perspective plane similar face each other, and follow closely area of the body pedestal 23 on the perspective plane on plane P and be greater than third segment body 213 on plane P
Perspective plane area.In this way, being more conducive to ensure in use process that 1 direction of blind rivet is consistent with initial installation direction always.
