An externally implanted mushroom-shaped tire repair device

Abstract

This utility model discloses an externally implanted mushroom-shaped tire repair device, relating to the field of tire repair tools. The repair patch includes a filler stem and a sealing strip. The filler stem is used to seal the tire's puncture hole, and the sealing strip is used to seal the tire's inner wall. The sealing strip rotates 90° and rolls up to wrap the filler stem. Through the connection and cooperation between a grinding cone, a packaging tube, a push tube, and a guide sheath tube, the filler stem and sealing strip can be easily inserted into the tire's interior and the location of the puncture hole. Vulcanizing adhesive is then injected to complete the repair. This achieves sealing treatment at two locations of the puncture hole, forming a double-safety structure. Under tire pressure, the sealing strip adheres tightly to the inner wall of the puncture hole, improving the sealing effect. Furthermore, due to the integrated structure of the filler stem and sealing strip, the sealing strip, pressed tightly against the tire's inner wall, locks the filler stem in the opposite direction, preventing it from slipping out of the puncture hole and ensuring the repair's durability.
