Description

Tyre repairing tool Technical Field The utility model relates to the field of tire repair, in particular to a tire repair tool. Background Currently, there are various injection molding tire repair methods and tools on the market, such as: 1. tyre repair adhesive tape (adhesive nail) The advantages are that: The operation is simple, the tire is not required to be disassembled, and the method is suitable for quick repair. Low cost, low cost of tools and materials. Portable, easy to carry and suitable for being used on a vehicle. Disadvantages: Temporary, namely, only emergency measures, poor reliability and possible air leakage after long-term use. The applicability is limited, and the method is only suitable for small holes and large damage and cannot be repaired. The tire may be damaged and mishandling may further damage the tire. 2. Tyre repairing liquid The advantages are that: the use is convenient, the tire is directly injected, and the leak is automatically filled. The anti-leakage device is quick and effective, can quickly stop leakage, and is suitable for emergency situations. The tool is not needed, the operation is simple, and the tool is suitable for non-professional people. Disadvantages: temporary-emergency only, long term use may affect tire balance. The cleaning is difficult, and the cleaning difficulty can be increased in the subsequent maintenance. Limited applicability, and no effectiveness for large holes or side wall damage. 3. Inner patch (Cold patch) The advantages are that: has strong durability and good repairing effect, and is suitable for long-term use. The application range is wide, and various types of injuries can be repaired. The balance is not affected, and the tire balance is less affected after repair. Disadvantages: The operation is complex, the tire is required to be disassembled, and the tire is suitable for professionals. Longer time consumption and longer repair time compared with other methods. Special tools are required, specific tools and materials are required. Therefore, there is a need for an efficient, reliable, convenient and low damage injection molding tire repair method and tool for various tires (including battery cars, motorcycles, and various automobiles). Disclosure of utility model The utility model solves the technical problem of providing a convenient and quick injection molding tire repairing method capable of reducing damage to tires. The technical scheme adopted by the utility model for solving the technical problems is that the injection molding tire repairing method comprises the following steps: S100, penetrating from the tire hole to the inner layer of the tire through a drilling tool; s200, determining the screwing depth through the inner layer hole; s300, feeding the elastic umbrella-shaped film into the tire from a through hole in the middle of the drilling tool through a feeding needle, opening the elastic umbrella-shaped film under the action of no external force after the elastic umbrella-shaped film enters the tire, and pulling a stay wire in the middle of the umbrella-shaped film to enable the edge of the umbrella-shaped film to be attached to the inner wall of the tire; S400, injecting a rubber repairing agent into the middle part of the drilling tool, so that the umbrella-shaped film and the cavity inside the tire are filled with the rubber repairing agent; s500, the drilling tool is retracted, and the stay wire is sheared after the rubber repairing agent is completely solidified.
