The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

First, a tire gauge 100 according to an embodiment of the present invention is described in detail with reference to fig. 1 to 4, and as shown in fig. 1 to 4, the tire gauge 100 includes a first roller set 1 and a driving member 110.

Wherein the first set of rollers 1 comprises a plurality of first rollers 11, the first rollers 11 being adapted to support the tread of a tire, wherein the tread of a tire refers to the surface of a tire adapted to be in contact with the ground. The drive 110 drives the first roller 11 in rotation about the central axis of the first roller 11 to rotate the tire about the axis of rotation of the tire.

It can be understood that the tread of the tire is supported on the plurality of first rollers 11, when the driving member 110 drives the first rollers 11 to rotate around the central axis of the first rollers, the tire supported on the first rollers 11 can rotate around the rotation axis of the tire, when the tire rotates, an operator can remove the rubber strips and burrs on the tire, for example, the operator can attach a cutter to the edge of the bead of the tire, and when the tire rotates, the burrs on the bead can be conveniently scraped off by the cutter.

According to the tire checking fixture 100 provided by the embodiment of the invention, the tire automatically rotates, so that the labor intensity of operators can be simplified, the operators can conveniently remove rubber strips and burrs on the tire, and the working efficiency is improved.

Alternatively, as shown in fig. 1-4, the tire gauge 100 may include a body 70, and the first roller 11 is rotatably mounted on the body 70 around a central axis of the first roller 11. Alternatively, the first roller 11 may be supported by a bearing.

In some preferred embodiments of the present invention, as shown in fig. 1, 2 and 4, the tire gauge 100 may further include a spreader 5, the spreader 5 being configured to spread the beads of the tire while the first roller 11 supports the tread of the tire.

That is to say, the tire expander 5 can strut the tire bead of tire, and the operating personnel of being convenient for observes the flaw (for example the burr on the border of tire bead) of tire inboard, and the tire can properly support through the tire expander 5 and press on first roller 11, and the first roller 11 of being convenient for drives the tire rotation.

In some preferred embodiments of the invention, the first set of rollers 1 may comprise a plurality of second rollers 12, the second rollers 12 being adapted to support sidewalls of the tire, i.e. the portion of the tire connected between the tread and the hub of the tire.

In other words, when the tire is rotated by the first roller 11, the sidewall of the tire rubs against the second roller 12, and the second roller 12 is rotated about its own rotation axis by the tire. Therefore, powerful support for the tire is achieved, and the tire side can be prevented from being scratched.

In some preferred embodiments of the present invention, a plurality of first rollers 11 may be arranged parallel to each other, and the central axis of each first roller 11 is at an angle of β degrees to the horizontal plane such that 10 DEG- β DEG-15 DEG is satisfied, and the free end of the first roller 11 is higher than the other end of the first roller 11.

It will be appreciated that the central axis of the second roller 12 may be substantially perpendicular to the central axis of the first roller 11, such that the tire may lean against the second roller 12 with the tread of the tire supported on the first roller 11 to prevent the tire from falling off the tire inspection tool 100 during rotation, and the inclination of the tire is small to facilitate the operator to hold a tool to remove burrs from the bead.

Preferably, as shown in fig. 1 to 3, the first roller 11 may be two.

It can be understood that in the embodiment that the number of the first rollers 11 is two, tires of various sizes can be supported on the two first rollers 11, and therefore, the application range of the tire checking fixture 100 is wide.

Preferably, as shown in fig. 1 and 4, the tire gauge 100 may further include a second roller set 2, the second roller set 2 may include a plurality of third rollers 23, and the third rollers 23 are adapted to support a tread of a tire. The second roller set 2 may further comprise a plurality of fourth rollers 24, the fourth rollers 24 being adapted to support sidewalls of the tire.

That is, in the manual inspection mode, the tread of the tire is supported on the third roller 23, the sidewall of the tire is supported on the fourth roller 24, the operator manually rotates the tire, the tread of the tire drives the third roller 23 to rotate around the central axis of the tire, the sidewall of the tire drives the fourth roller 24 to rotate around the central axis of the tire, and by arranging the third roller 23 and the fourth roller 24, the rotation of the tire is smooth, the operation of the operator is labor-saving, and the abrasion to the tire is very small.

In the tire rotation process, operating personnel can inspect the flaw on the tread and the side wall of tire, for example whether have the adhesive tape, if the adhesive tape is less, operating personnel can manually get rid of, if the adhesive tape is more, can utilize the automatic rotation of tire to use the cutter to get rid of when the tread of tire supports on first roller 11.

Further, as shown in fig. 1, the number of the third rollers 23 may be two.

It can be understood that in the embodiment where there are two third rollers 23, tires of various sizes can be supported on the two third rollers 23, and thus, the application range of the tire checking fixture 100 is wide.

It will be understood that the operator, with the tyre supported on the second set of rollers 2, can check the defects on the tread and sidewalls of the tyre by manually rotating the tyre, and that, with the tyre supported on the first set of rollers 1, the tyre is automatically rotated under the drive of the first rollers 11, and the operator can check the defects on the beads of the tyre.

Preferably, as shown in fig. 1, the tire gauge 100 may further include a viewing mirror 6, and the viewing mirror 6 is used for reflecting the reflected light of the tread of the tire. Alternatively, the observation mirror 6 may be mounted on the body 70.

It can be understood that when the operator inspects the tire, the operator faces the sidewall of the tire, if the operator needs to directly observe the tread of the tire, the operator needs to bend down to observe from the side direction, and by arranging the observation mirror 6 in the above structure, the operator can observe the tread of the tire in an upright state through the reflection of the observation mirror 6, thereby greatly reducing the labor intensity of the operator and improving the working efficiency of the operator. For example, when the third roller 23 supports the tread of the tire, the operator can observe the tread of the tire by reflection of the observation mirror 6 while manually rotating the tire in an upright state; when the first roller 11 supports the tread of the tire, the operator can observe the edge of the bead of the tire in an upright state and observe the tread of the tire by reflection of the observation mirror 6.

Further, the third roller 23 is rotatable about the rotational axis of the third roller 23. It will be appreciated that as the third roller 23 rotates above the first roller 11, the tread of the tyre may be supported on the third roller 23 to manually rotate the tyre, and as the third roller 23 rotates below the first roller 11, the tyre may fall onto the first roller 11 to cause the tyre to rotate automatically. Thus, the first roller 11 and the third roller 23 do not interfere with each other, and the tire position can be switched easily without manual movement.
