Description

Tire repair tool and tire repair method

Technical field

The present invention relates to the technical field of tire repair tools, and specifically relates to a tire repair tool and a tire repair method thereof.

Background technique

After a vehicle tire is punctured, it needs to be repaired. Traditional tire repair methods need to be carried out in repair shops or mobile tire repair stations. Usually, the tire needs to be removed from the wheel hub, and a film is pasted from the inner wall of the tire to seal the leak. The tire repair process is cumbersome, takes a long time to repair, and requires a special tire. Disassembly and assembly of equipment.

With the development of technology, in order to quickly and conveniently repair tires, some simple tire repair methods have emerged, such as sticking rubber strips and using a special awl to poke the rubber-covered rubber strip into the damaged part of the tire, leaving part of it in place. Externally, the advantage is that there is no need to disassemble the tire and rim, and there is no need to re-balance the dynamic, and the repair is very fast; the disadvantage is that when the cone is inserted into the leak hole, the original hole will be enlarged, and there may be a slow air leakage problem. At the same time, this method can be repaired. The distance that can be traveled is shorter.

It can be seen from this that there are some problems in both the traditional tire disassembly and tire repair methods and the existing rubber strip method. Therefore, a new tire repair tool is needed for tire repair to solve the above problems.

(6) Then inflate tire 1 to 60%-70% of the normal air pressure, and after 5 minutes inflate it to normal air pressure, that is, the repair of tire 1 is completed.

The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, as follows:

In the present invention, the outer tube 2 can be set to a variety of specifications. The length of the outer tube 2 is set to 20cm, including the handle 21. The lower outer diameter of the outer tube 2 can be set to 4.5cm, 5cm and 6cm, and the corresponding inner diameters are 4cm and 4.4cm. and 5.4cm, the unfolded diameter of the wire umbrella 4 is set to 1.5cm, 2.0cm and 2.5cm correspondingly. The larger the loophole 11 is, the diameter of the wire umbrella 4 is approximately larger. The length of the middle tube 3 is set to 25cm, the outer diameter is 3.5cm, and the rubber hose The length is also set to 25cm and the outer diameter is 3.5cm. The materials of the outer tube 2, the middle tube 3 and the hose are all made of 304 stainless steel. The dimensions in the illustrations in the manual do not represent the actual dimensions.

In the present invention, the diameter of the outer tube 2 is selected based on the diameter of the tire 1 to be punctured. If the normal value is below 6 mm, the tool of the present invention can be used to repair the tire. According to Figures 1-10 of the instruction manual, after selecting the appropriate outer tube 2, turn the tire 1 with the hole 11 to be repaired upwards, insert the lower part of the outer tube 2 into the hole 11 of the car tire 1, and place the lower end inside the tire 1, and the car The thickness of the tire 1 is generally about 1.3-1.5cm, and the lower part of the outer tube 2 is enough to be inserted into it; then the personnel manually wrap the steel wire umbrella 4 around the front end of the middle tube 3. Since the elastic steel wire 42 in the steel wire umbrella 4 has a certain elasticity, it requires the support of the personnel And stuff it into the middle cavity of the outer tube 2, then use the middle tube 3 to push the steel wire umbrella 4 downward, insert it into the inside of the tire 1, and leave the nylon thread 5 outside the tire 1; after the entire steel wire umbrella 4 is inserted into the inside of the tire 1, the steel wire The restoring force of the elastic steel wire 42 on the umbrella 4 will open the nylon cloth 41, and the personnel pulls the nylon wire 5 to make the steel wire umbrella 4 contact the inner wall of the tire 1, thereby making it fully open; then, the middle tube 3 is pulled out, and the personnel inserts the rubber hose. Go to the middle cavity of the outer tube 2 and place the lower end of the hose at the lower end of the outer tube 2, and inject glue. The glue will flow onto the nylon cloth 41 of the steel mesh. After the glue injection is completed, pull out the hose and outer tube 2, and pull the nylon again. Line 5 makes the steel wire umbrella 4 fit the inner wall of tire 1, so that the glue between them bonds the two; finally, tire 1 is inflated to 60%-70% of the normal air pressure, and the internal air pressure in tire 1 makes the steel wire The umbrella 4 is more closely attached to the inner wall of the tire 1. After 5 minutes, the tire is inflated to normal pressure, and the repair of the tire 1 is completed. It should be noted here that the present invention requires a small air pump. Compared with the prior art, the present invention does not require disassembly of the tire 1 and can be operated by non-professionals. First, insert the outer tube 2 into the leak hole, and then use the middle tube 3 to push the steel wire umbrella 4 into the interior of the tire 1 and pull the steel wire. The nylon thread 5 connected to the umbrella 4 is fastened to the hole 11 on the inner wall of the tire 1, and then inserted into the outer tube 2 through the rubber tube, and glue is added to the steel wire umbrella 4. Finally, by pulling the nylon thread 5 and stamping inside the tire, The steel wire umbrella 4 seals the inner wall of the tire 1, and the bonding effect is good, and the tire repair tool has a simple structure, and can be manually operated by personnel anytime and anywhere, making it easy to use.

One possible implementation method is that the upper part of the outer tube 2 is conical, with an outer diameter of 12cm and an inner diameter of 11.4cm. The lower part of the outer tube 2 is tubular and is made in one piece. The upper end of the outer tube 2 is provided with a handle 21, and the handle 21 corresponds to A through hole 22 is provided in the middle cavity of the outer tube 2 to facilitate personnel to insert the outer tube 2 into the interior of the tire 1, which saves effort. The outer tube 2 is stronger and facilitates the insertion of the middle tube 3 and the rubber hose. The lower part of the outer tube 2 is provided with a clamp 23 at a distance of 3cm/4cm/5cm from the lower end. The clamp 23 set on the outer tube 2 can be inserted into the slot of the outer tube 2 through a bayonet and fixed at different depths. According to different types of tires 1. Select the position. The thicker the wall thickness of tire 1, the deeper the lower part of outer tube 2 is inserted to ensure that the subsequent steel wire umbrella 4 can be fully deployed. At the same time, the insertion depth of steel wire umbrella 4 is just right to ensure the subsequent gluing effect.

One possible implementation method is that the hoses include hose A6, hose B7 and hose C8, and hose A6, hose B7 and hose C8 are injected with glue in sequence. The glue in hose A6 can spread on the nylon cloth 41 of the wire umbrella 4, and on the nylon cloth 41 of the wire umbrella 4. The edge contour line 43 is gathered together and solidified to form a ring of convex ring 61. Multiple equal amounts of glue injection, diffusion, and solidification can be used to form a ring of convex ring 61 with a certain blocking function, which provides a good foundation for the subsequent injection of hose B7. Prepare the glue to prevent it from flowing out of the wire umbrella 4 to ensure the amount of glue. The glue in the hose B7 can be filled inside the raised ring 61 for subsequent adhesion with the inner wall of the tire 1. The glue in the hose C8 can be filled in the wire umbrella 4. A hemispherical protrusion 81 is formed at the center. The hemispherical protrusion 81 is formed by multiple glue injection and curing methods. The size of the formed protrusion 81 is slightly larger than the size of the hole 11. Since internal repair personnel cannot observe it, this method can ensure the glue coating and repair effects and is very practical.

Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art will understand that various changes, modifications, and substitutions can be made to these embodiments without departing from the principles and spirit of the invention. and modifications, the scope of the invention is defined by the appended claims and their equivalents.
