Technical Field

The invention relates to the technical field of tire repairing devices for vacuum tires, in particular to a pull rivet type tire repairing nail.

Background

The vacuum tire is a pneumatic tire without an inner tube, also called a low-pressure tire or a pneumatic tire, and has high elasticity and wear resistance, good adhesive force and heat dissipation performance. Vacuum tires are increasingly used on bicycles, motorcycles, cars, passenger cars, and trucks.

The vacuum tire is divided into three parts: carcass, cord fabric, tread. The tyre body is softer, the rigidity of the outer tyre surface is larger, the middle cord thread plays a role in reinforcing the strength and shaping of the tyre body, and the metal wire is additionally added to improve the elastic performance of the tyre.

At present, two methods are generally adopted when the tire is repaired, wherein one method is to directly attach a tire repairing paste on an inner liner of the tire, and the other method is to repair the tire through mushroom nails. However, both of these two tire repair methods have certain limitations, that is, after the damaged portion of the tire is ground into a regular through hole, if the hole diameter exceeds 6mm, tire repair is generally not recommended, and in addition, repair is generally not recommended for the damaged portion of the sidewall, because the effect after tire repair is poor, tire replacement is recommended, which increases the use cost and reduces the service life of the tire. The main reason is that after the damaged part is large in size or located at the damaged part of the tire side, even after tire repair, because the through hole has no supporting force, when the tire runs under rated air pressure, the tire bulges at the tire repair part, and the tire puncture phenomenon may happen seriously. In addition, the tyre can not be repaired by the mushroom nails when the inclination of the through holes at the damaged positions is larger than 15 degrees, and the tyre repairing effect is poor mainly because the sealing condition between the mushroom nails and the through holes is influenced if the inclination is too large.
