Description

[Detailed description of the invention] This invention relates to a repair material for tubeless tires that repairs scratches caused by nails, wires, etc. on tires. To provide a repair material that can be easily applied with provided pliers or a screwdriver and completely prevents falling off from the wound after repairing the wound.

Conventional repair materials of this type include a long piece of rubber or a cylindrical rubber body with a hollow portion in the axial direction. In this case, the process must be carried out using cone-shaped tools, each of which has a special shape, and is a tool that is installed in the car.

For example, there is a drawback that the filling operation cannot be performed using pliers or a screwdriver.

Furthermore, the former two-pronged tool has drawbacks such as the protrusion on one side causing new lacerations in the tire.

Furthermore, the latter hollow cylindrical body has the disadvantage that when the concave tool is removed from the hollow part after filling the tire wound, the hollow part deforms into a flat shape, weakening the sealing force of the tire wound.

The present invention completely eliminates the above-mentioned conventional drawbacks, and will be described in detail below according to the illustrations of the embodiments. Figure 1 is a front view of the repair material, and the cylindrical approximation body 1 made of elastic rubber is circular in cross section or Figure 3 is a front view of the repair material. As shown in the figure, the diameter of the cylindrical approximation body 1 is tapered gradually from the tip to the root, and there are screws on the outer circumferential surface. A shaped protruding strip 2 is integrally formed.

A hard wire 3 such as a metal wire is embedded in the axial portion of the cylindrical approximation body 1, and the root of the cylindrical approximation body 1 is formed into a stepped large diameter portion 4. A hard piece 5 such as a metal plate is vertically buried perpendicular to the axis, and a screwdriver insertion frame 6 with a downward opening is integrally buried at the base of the cylindrical approximation body 1, which also serves as the hard piece 5. has been done.

The present invention has the above-mentioned configuration, and the diameter of the cylindrical approximation body 1 is tapered to a large diameter from the tip to the base, and the screw-down protruding strip 2 is formed on the outer peripheral surface.

The cylindrical approximation body 1 can be screwed into the lower part of the tire while being rotated, so that the wound can be repaired easily and quickly.The hard wire rod 3 embedded inside prevents the cylindrical approximation body 1 made of elastic rubber from shifting in direction or being improperly deformed. The screw-in operation is ensured, and the stepped large-diameter portion 4 prevents the cylindrical approximation body 1 from being screwed into the lower part of the tire wound too much.
As shown in Fig. 5, the hard piece 5 embedded in the large diameter part 4 serves as a core material when the large diameter part 4 is held between the pliers 8 and ensures that the cylindrical approximation body can be screwed in 10 turns using the pliers 8. year,
In addition, the driver insertion frame 6 is as shown in FIG.
If you insert the driver 9 into this and fit it, the driver 9
The pressurized rotational force is reliably transmitted to the cylindrical approximation body 1, and the cylindrical approximation body 1 is filled with the tire damage lower 4C, and as shown in Figure 7, the large diameter portion 4 is removed to complete the repair of the tire damage lower. However, since the driver 9 is always at the base and outside the tire, it can be easily removed without being pressed against the cylindrical approximation, and once inserted into the wound, the cylindrical approximation is fixed and the seal is secure. Become.

However, since the cylindrical approximation body 1 is secured to the tire flaw lower by screwing, the evaporation of the cylindrical approximation body 1 from the tire flaw lower is completely prevented, and the cylindrical approximation body 1 is moved from the tire by the frictional heat generated by driving the car. By melting and integrating the 104C tire damage lower, the tire damage lower is restored to its original, intact shape, allowing its continued use.
