Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.

As shown in fig. 1-3, a center bolt for a tire comprises a body 1, a forward thread 6 is arranged on the surface of the body 1, a smooth surface 5 is arranged on the surface of the body 1 and on the right side of the forward thread 6, and a reverse thread 4 is arranged on the surface of the body 1 and on the right side of the smooth surface 5.

One end of the body 1 is provided with a hexagonal head 2, and the surface of the hexagonal head 2 is provided with a hexagonal opening 3.

One end of the body 1 and one side of the forward thread 6 are provided with round mouths 7.

The body 1 comprises an antirust material 13, a pressure-resistant material 12 is arranged at the bottom of the antirust material 13, and a steel material 11 is arranged at the bottom of the pressure-resistant material 12.

It should be noted that, the utility model is a center shaft bolt for a tire, when in use, the hexagon wrench is aligned to the hexagon mouth 3, the rotation of the hexagon mouth 3 through the hexagon wrench drives the body 1 to rotate through the rotation of the hexagon head 2, one end of the body 1 is aligned to a position to be fixed, when the forward thread 6 contacts the hexagon mouth, the body 1 moves to one side through the stress of the forward thread 6, when the body contacts the smooth surface 5, the body 1 can rotate smoothly, a buffer is formed on the body 1, when the body 1 contacts the reverse thread 4, the body 1 is driven to rotate reversely, the center shaft bolt is fastened more, the body 1 can be firmer and more durable through the use of the steel material 11, the body 1 can be stronger in the rotation through the use of the compression-resistant material 12, the corrosion and rust of the body 1 caused by the long-age use can be prevented through the use of the antirust material 13, so that the use ratio of the body 1 can be enhanced.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
