Description

Technical Field

[0001] The present invention relates to the technical field of tire repair tools, and specifically to a tire repair tool and a tire repair method therefor. Background Art

[0002] After a vehicle tire is punctured and leaks, repair is required. Traditional tire repair methods need to be carried out in a repair shop or a mobile tire repair point. Usually, the tire needs to be removed from the wheel hub, and a film is pasted on the inner wall of the tire to block the leak hole. The tire repair process is cumbersome, the repair time is long, and special disassembly and assembly equipment is required.

[0003] With the development of technology, in order to quickly and conveniently repair tires, some simple tire repair methods have emerged at present, such as inserting a rubber strip. A rubber strip coated with glue is inserted into the damaged part of the tire using a special awl, and a part is left outside. The advantages are that the tire and the rim do not need to be disassembled, and no rebalancing is required, and the repair is very fast; the disadvantages are that the original hole will be enlarged when the awl is inserted into the leak hole, there may be a slow air leakage problem, and the distance that can be traveled after repair is short.

[0004] It can be seen from this that both the traditional disassembly and tire repair method and the existing rubber strip insertion method have some problems. Therefore, a new tire repair tool is needed to repair tires to solve the above problems. Summary of the Invention

[0005] In view of the above deficiencies of the prior art, the present invention provides a tire repair tool and a tire repair method therefor, which do not require tire disassembly and can be operated by non-professionals. First, the outer tube is inserted into the leak hole, then the middle tube is used to push the steel wire umbrella into the tire interior, the nylon line connected to the steel wire umbrella is pulled to make it buckle at the leak on the inner side wall of the tire, then the rubber tube is inserted into the outer tube, and glue is applied to the steel wire umbrella. Finally, by pulling the nylon line and inflating the tire interior, the steel wire umbrella seals the inner side wall of the tire, with good bonding effect, and the tire repair tool has a simple structure and can be manually operated by personnel at any time and place, which is convenient to use.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0007] A tire repair tool includes an outer tube, a middle tube, a rubber tube, a wire umbrella, and a nylon thread. The lower part of the outer tube can be inserted into the hole of the tire and the lower end is placed inside the tire. The middle tube can be inserted into the middle cavity of the outer tube and the lower end of the middle tube is placed at the position of the lower end of the outer tube. The wire umbrella includes a plurality of elastic wires and a circular nylon cloth. The plurality of elastic wires are evenly distributed through the center of the nylon cloth. The wire umbrella can gather towards one side in the axial direction with its center as the center. The middle tube can push the center of the wire umbrella to insert it into the outer tube and push it into the tire interior. One end of the nylon thread is fixedly connected to the center of the nylon cloth and the other end is placed outside the tire. Pulling the nylon thread can make the wire umbrella fully open inside the tire. The rubber tube can be inserted into the middle cavity of the outer tube and extend into the tire interior to inject glue into the wire umbrella. After injecting the glue, pulling the nylon thread can make the wire umbrella adhere to the side wall near the tire hole.

[0008] Preferably, the upper part of the outer tube has a conical shape and the lower part is tubular, and it is integrally formed. A handle is provided at the upper end of the outer tube, and a through hole is opened in the handle corresponding to the position of the middle cavity of the outer tube.

[0009] Preferably, the outer tube is provided with a card slot at a distance of 3 cm / 4 cm / 5 cm from the lower end. A clamp is vertically movably sleeved at the central position of the outer tube, and a latch is slidably arranged on the clamp. The latch can be inserted into the card slot.

[0010] Preferably, the rubber tube includes rubber tube A, rubber tube B, and rubber tube C, and the glue is injected in sequence in rubber tube A, rubber tube B, and rubber tube C. A contour line is provided on the nylon cloth of the wire umbrella. The glue in rubber tube A can diffuse on the nylon cloth of the wire umbrella and gather at the edge contour line, and form a convex ring after curing. The glue in rubber tube B can fill the inside of the convex ring to form a flat shape. The glue in rubber tube C can form a hemispherical protrusion at the center position of the wire umbrella.

[0011] Preferably, the materials of the rubber tube, the outer tube, and the middle tube are all 304 stainless steel.

[0012] Preferably, the method for repairing a tire with this repair tool is as follows:

[0013] (1) Place the tire with the leak point facing up, insert the lower part of the outer tube into the hole of the tire and place the lower end inside the tire;

[0014] (2) Manually wrap the wire umbrella around the front end of the middle tube by a person and stuff it into the middle cavity of the outer tube. Use the middle tube to push the wire umbrella downward and insert it into the tire interior. The nylon thread remains outside;

[0015] (3) After the entire wire umbrella is inserted into the tire interior, the restoring force of the elastic wires on the wire umbrella will open the nylon cloth. The person pulls the nylon thread to make the wire umbrella fully open inside the tire;

[0016] 4. Pull out the middle tube. The operator inserts the rubber hose into the inner cavity of the outer tube and positions the lower end of the rubber hose at the lower end of the outer tube, and then injects glue.

[0017] 5. After the glue injection is completed, pull out the rubber hose and the outer tube. Then, pull the nylon thread again to make the steel wire umbrella fit the inner wall of the tire, so that the glue between them bonds the two.

[0018] 6. Then inflate the tire to 60%-70% of the normal air pressure. After 5 minutes, inflate it to the normal air pressure, and the tire repair is completed.

[0019] The present invention provides a tire repair tool and a tire repair method, which have the following beneficial effects:

[0020] 1. The present invention does not require tire disassembly and can be operated by non-professionals. First, insert the outer tube into the leak hole, then use the middle tube to push the steel wire umbrella into the tire interior, pull the nylon thread connected to the steel wire umbrella to make it buckle at the leak on the inner wall of the tire, then insert the rubber hose into the outer tube and apply glue to the steel wire umbrella. Finally, through pulling the nylon thread and inflating the tire interior, the steel wire umbrella seals the inner wall of the tire, with good bonding effect. Moreover, the tire repair tool has a simple structure and can be manually operated by personnel at any time and place, which is convenient to use.

[0021] 2. The upper end of the outer tube of the present invention is provided with a handle, which is convenient for the operator to insert the outer tube into the tire interior, saving effort and avoiding hand injury.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Such as Figures 1-10As shown in the figure, a tire repair tool includes an outer tube 2, a middle tube 3, a rubber tube, a wire umbrella 4 and a nylon thread 5. The lower part of the outer tube 2 can be inserted into the hole 11 of the tire 1 and the lower end is placed inside the tire 1. The middle tube 3 can be inserted into the middle cavity of the outer tube 2 and the lower end of the middle tube 3 is placed at the lower end position of the outer tube 2. The wire umbrella 4 includes a plurality of elastic wires 42 and a circular nylon cloth 41. The plurality of elastic wires 42 respectively pass through the center of the nylon cloth 41 and are evenly distributed. The wire umbrella 4 can gather towards one side of the axis with its center as the center. The middle tube 3 can push the center of the wire umbrella 4 to insert it into the outer tube 2 and push it into the tire 1. One end of the nylon thread 5 is fixedly connected to the center of the nylon cloth 41 and the other end is placed outside the tire 1. Pulling the nylon thread 5 can completely open the wire umbrella 4 inside the tire 1. The rubber tube can be inserted into the middle cavity of the outer tube 2 and extend into the tire 1 to inject glue into the wire umbrella 4. After injecting glue, pulling the nylon thread 5 can make the wire umbrella 4 adhere to the side wall near the hole 11 of the tire 1. The upper part of the outer tube 2 is conical in shape and the lower part is tubular, and it is integrally formed. A handle 21 is provided at the upper end of the outer tube 2, and a through hole 22 is provided in the handle 21 corresponding to the middle cavity position of the outer tube 2. The outer tube 2 is provided with a card slot at a position 3 cm / 4 cm / 5 cm away from the lower end. A clamp 23 is vertically movably sleeved at the central position of the outer tube 2, and a pin is slidably arranged on the clamp 23. The pin can be inserted into the card slot. The rubber tube includes a rubber tube A6, a rubber tube B7 and a rubber tube C8, and the rubber tube A6, the rubber tube B7 and the rubber tube C8 inject glue in sequence. A contour line 43 is provided on the nylon cloth 41 of the wire umbrella 4. The glue in the rubber tube A6 can spread on the nylon cloth 41 of the wire umbrella 4 and gather at the edge contour line 43. After curing, a convex ring 61 is formed. The glue in the rubber tube B7 can fill the inside of the convex ring 61 to form a flat shape 71. The glue in the rubber tube C8 can form a hemispherical protrusion 81 at the central position of the wire umbrella 4. The materials of the rubber tube, the outer tube 2 and the middle tube 3 are all 304 stainless steel.

[0037] The tire repair method of the above repair tool is as follows:

[0038] (1) Place the tire 1 with the leak point facing upwards, insert the lower part of the outer tube 2 into the hole 11 of the tire 1 and place the lower end inside the tire 1.

[0039] (2) Manually wrap the wire umbrella 4 around the front end of the middle tube 3 and stuff it into the middle cavity of the outer tube 2. Use the middle tube 3 to push the wire umbrella 4 downwards and insert it into the tire 1, leaving the nylon thread 5 outside.

[0040] (3) After the entire wire umbrella 4 is inserted into the tire 1, the restoring force of the elastic wires 42 on the wire umbrella 4 will open the nylon cloth 41. The operator pulls the nylon thread 5 to completely open the wire umbrella 4 inside the tire 1.

[0041] (4) Pull out the middle tube 3. The operator inserts the rubber tube into the inner cavity of the outer tube 2 and places the lower end of the rubber tube at the lower end of the outer tube 2 to inject glue.

[0042] (5) After the glue injection is completed, pull out the rubber tube and the outer tube 2. Pull the nylon thread 5 again to make the steel wire umbrella 4 fit against the inner wall of the tire 1, so that the glue between them bonds the two together.

[0043] (6) Then inflate the tire 1 to 60%-70% of the normal air pressure. After 5 minutes, inflate it to the normal air pressure, and the repair of the tire 1 is completed.

[0044] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, which are as follows:

[0045] In the present invention, the outer tube 2 can be set in various specifications. The length of the outer tube 2 is set to 20 cm, including a handle 21. The outer diameter of the lower part of the outer tube 2 can be set to 4.5 cm, 5 cm, and 6 cm, and the corresponding inner diameters are 4 cm, 4.4 cm, and 5.4 cm. The unfolded diameter of the steel wire umbrella 4 is correspondingly set to 1.5 cm, 2.0 cm, and 2.5 cm. The larger the hole 11 is, the larger the diameter of the steel wire umbrella 4 is. The length of the middle tube 3 is set to 25 cm, the outer diameter is 3.5 cm, and the length of the rubber tube is also set to 25 cm, and the outer diameter is 3.5 cm. The materials of the above outer tube 2, middle tube 3, and rubber tube are all made of 304 stainless steel. The dimensions in the attached drawings of the specification do not represent the actual dimensions.

[0046] In the present invention, the diameter of the outer tube 2 is selected according to the diameter of the object that punctures the tire 1. When the normal value is below 6 mm, the tool of the present invention can be used to repair the tire. According to the attached Figures 1-10It can be seen that after selecting the appropriate outer tube 2, with the puncture 11 of the tire 1 facing upwards, insert the lower part of the outer tube 2 into the puncture 11 of the tire 1 and place the lower end inside the tire 1. The thickness of the tire 1 is generally about 1.3 - 1.5 cm, and the lower part of the outer tube 2 is sufficient to be inserted therein. Then, manually wrap the wire umbrella 4 around the front end of the middle tube 3 by the operator. Since the elastic wire 42 in the wire umbrella 4 has a certain elasticity, the operator needs to hold and stuff it into the middle cavity of the outer tube 2, and then use the middle tube 3 to push the wire umbrella 4 downward and insert it into the tire 1. The nylon thread 5 remains outside the tire 1. After the entire wire umbrella 4 is inserted into the tire 1, the restoring force of the elastic wire 42 on the wire umbrella 4 will cause the nylon cloth 41 to open. The operator pulls the nylon thread 5 to make the wire umbrella 4 contact the inner sidewall of the tire 1, so that it fully opens. Then, pull out the middle tube 3. The operator inserts the rubber tube into the middle cavity of the outer tube 2 and places the lower end of the rubber tube at the position of the lower end of the outer tube 2 to inject glue, and the glue flows onto the nylon cloth 41 of the wire mesh. After the glue injection is completed, pull out the rubber tube and the outer tube 2. Pull the nylon thread 5 again to make the wire umbrella 4 fit the inner sidewall of the tire 1, so that the glue between them bonds the two. Finally, inflate the tire 1 to 60% - 70% of the normal air pressure. The internal air pressure in the tire 1 makes the wire umbrella 4 fit more tightly with the inner sidewall of the tire 1. After 5 minutes, inflate it to the normal air pressure, and the repair of the tire 1 is completed. It should be noted here that a small air pump needs to be configured for the present invention. Compared with the prior art, the present invention does not require the disassembly of the tire 1, and non-professionals can operate it. First, insert the outer tube 2 into the leak hole, then use the middle tube 3 to push the wire umbrella 4 into the tire 1, pull the nylon thread 5 connected to the wire umbrella 4 to make it buckle at the puncture 11 on the inner sidewall of the tire 1, then insert the rubber tube into the outer tube 2 to apply glue to the wire umbrella 4, and finally, through pulling the nylon thread 5 and inflating the tire, the wire umbrella 4 seals the inner sidewall of the tire 1, with good bonding effect, and the tire repair tool has a simple structure, and the operator can perform manual operation anytime and anywhere, which is convenient to use.

[0047] In a possible implementation manner, the upper part of the outer tube 2 is conical, with an outer diameter of 12 cm and an inner diameter of 11.4 cm at the upper part. The lower part of the outer tube 2 is tubular and is integrally formed. A handle 21 is provided at the upper end of the outer tube 2, and a through hole 22 is opened at the handle 21 corresponding to the position of the middle cavity of the outer tube 2, which is convenient for the operator to insert the outer tube 2 into the tire 1, saving effort, making the outer tube 2 more solid, and facilitating the insertion of the middle tube 3 and the rubber tube. A clamp 23 is provided at a position 3 cm / 4 cm / 5 cm away from the lower end of the lower part of the outer tube 2. The clamp 23 sleeved on the outer tube 2 can be fixed at different depths by inserting a pin into the card slot of the outer tube 2, and the position is selected according to different models of the tire 1. The thicker the wall thickness of the tire 1, the deeper the lower part of the outer tube 2 is inserted, ensuring that the wire umbrella 4 can be fully unfolded later, and at the same time, the insertion depth of the wire umbrella 4 is just right to ensure the subsequent glue application effect.

[0048] A possible implementation is that the rubber hose includes rubber hose A6, rubber hose B7, and rubber hose C8. The rubber in rubber hose A6, rubber hose B7, and rubber hose C8 is injected in sequence. The rubber in rubber hose A6 can spread on the nylon cloth 41 of the steel wire umbrella 4 and gather at the edge contour line 43, and then solidify to form a convex ring 61. The method of injecting the same amount of glue, spreading, and solidifying multiple times can be used to form a convex ring 61 with a certain blocking function, which is prepared for the glue injected into rubber hose B7 later to prevent it from flowing out of the steel wire umbrella 4 to ensure the amount of glue. The glue in rubber hose B7 can fill the inside of the convex ring 61 and is used for subsequent adhesion to the inner side wall of the tire 1. The glue in rubber hose C8 can form a hemispherical protrusion 81 at the center position of the steel wire umbrella 4. The hemispherical protrusion 81 is formed by the method of injecting glue and solidifying multiple times. The size of the formed protrusion 81 is slightly larger than the size of the hole 11. Since the internal repair personnel cannot observe it, this method can ensure the glue application effect and the repair effect, and has strong practicability.

[0049] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
