Description

Technical Field

[0001] This invention relates to the field of tire repair technology, and in particular to a tire repair tool. Background Technology

[0002] Currently, the most common tire repair methods on the market include hot patching, filling with rubber strips and vulcanizing agents, and implanting rubber patch fillers. Hot patching requires a professional shop and involves tire removal and rebalancing. While highly reliable, it is cumbersome, time-consuming, and inconvenient. Rubber strip filling and traditional patch filler implantation methods can achieve rapid on-site repair to some extent, but still suffer from high operational resistance, easy rotation or misalignment of the patch filler, and insufficient sealing reliability, affecting repair success rate and long-term durability. To improve operational convenience and repair reliability, a patch filler implantation device based on a push-rod type tire repair tool has emerged in recent years. This typically includes a main body, push rod, probe, and guide head. This type of tool aims to achieve rapid repair without tire removal, but in actual use, it still suffers from excessive pushing force, laborious operation, and the patch filler's tendency to rotate or shear during insertion, damaging the patch filler and leading to unsatisfactory sealing or implantation failure.

[0003] Therefore, it is necessary to propose a brand-new tire repair tool that can prevent the tire repair filler from rotating and being damaged during the insertion process, thereby improving the reliability and durability of the tire repair operation. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the tire repair tool provided by the present invention can prevent the tire repair filler from rotating and being damaged during the pushing process, thereby improving the reliability and durability of the tire repair operation.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] The tire repair tool provided by the present invention includes a main body, a guide head, and a pushing device. The main body has an installation channel inside. The guide head is detachably connected to the front end of the main body and has a guide outlet and a guide channel, and the guide outlet and the guide channel are connected to the installation channel. The pushing device can slide linearly in the installation channel. The pushing device is used to push the tire repair filler in the installation channel to move linearly from the installation channel to the guide channel, and to push at least a portion of the tire repair filler to pass through the guide channel and extend from the guide outlet into the tire to seal the tire puncture hole.

[0007] The tire repair tool of the present invention includes a pushing device comprising a push rod, a top rod, and a pin connected to the top rod. The front end of the top rod abuts against the tire repair filler. The push rod pushes the top rod to slide within the installation channel, thereby moving the tire repair filler to the tire puncture hole to repair the puncture. By setting the pin, the rotational movement of the top rod within the installation channel is restricted, thus ensuring that the top rod maintains linear movement within the installation channel. This also ensures that the tire repair filler maintains linear movement throughout the pushing process, preventing the tire repair filler from twisting and being damaged during pushing. Furthermore, when the top rod pushes at least a portion of the tire repair filler out of the guide channel and extends from the guide outlet into the tire to seal the tire puncture hole, the user can move the top rod via the pin to release the pushing and squeezing of the tire repair filler. At this time, the tire repair filler can be fully released and stretched within the guide channel, avoiding excessive squeezing and accumulation of the tire repair filler at a certain position in the guide channel, which could cause localized cutting points and damage to the tire repair filler, thus ensuring the integrity of the tire repair filler.

[0008] In addition, the pin can also limit the movement distance of the pushing device in the installation channel, thereby limiting the depth of the tire patch filler into the installation channel, thus controlling the pushing stroke of the tire patch filler to avoid damage to the tire patch filler during the pushing process;

[0009] Additionally, the pin can also be used as a handle, assisting the user in quickly and easily removing the guide head from the tire when pulling it out. Attached Figure Description

[0026] This invention discloses a tire repair tool 100, such as... Figures 1-6 As shown, the device includes a main body 1, a guide head 2, and a pushing device. The main body 1 has an installation channel 11 inside. The guide head 2 is detachably connected to the front end of the main body 1. The guide head 2 has a guide outlet 21 and a guide channel 22, and the guide outlet 21 and the guide channel 22 are connected to the installation channel 11. The pushing device can slide linearly within the installation channel 11. The pushing device is used to push the tire patch filler 6 in the installation channel 11 to move linearly from the installation channel 11 to the guide channel 22, and to push at least a portion of the tire patch filler 6 out of the guide channel 22 and extend from the guide outlet 21 into the tire to seal the tire puncture hole.

[0027] With the above structure, the pushing device can keep the tire patch filler 6 moving linearly in the mounting channel 11 and the guide channel 22, avoiding the tire patch filler 6 from twisting during the pushing process and damaging the tire patch filler 6, thereby improving the reliability and durability of the tire patch filler 6.

[0028] In this embodiment, the pushing device includes a pushing part 4 and a pin 5 connected to the pushing part 4. A limiting groove 12 is provided on the main body 1. The pin 5 can slide in the limiting groove 12. The pin 5 is used to prevent the pushing part 4 from rotating in the mounting channel 11, so that the pushing part 4 maintains linear sliding in the mounting channel 11. The pushing part 4 pushes at least a portion of the tire filler 6 out of the guide channel 22 by linear sliding.

[0029] In this embodiment, as Figures 1-2 as well as Figures 5-6 As shown, the pin 5 can move between a first position and a second position. The limiting groove 12 has a front stop edge 121 and a rear stop edge 122. When the pin 5 moves to the second position, the pin 5 abuts against the rear stop edge 122, and the distance between the pushing end 433 of the pushing device and the guide outlet 21 is minimized. The pushing device is used to push at least a portion of the tire filler 6 through the guide outlet 21 and out of the guide channel 22, and the guide channel 22 is used to accommodate at least a portion of the tire filler 6. When the pin 5 moves to the first position, the pin 5 abuts against the front stop edge 121, and the pushing device... The distance between the pushing end 433 and the guide outlet 21 is the largest. The pushing end 433 releases the pushing of the tire repair filler 6, allowing the tire repair filler 6 to be fully released and spread out in the guide channel 22. This prevents the tire repair filler 6 from being over-compressed and accumulating in a certain position in the guide channel 22, which would cause local cutting points and damage to the tire repair filler 6. This ensures the integrity of the tire repair filler 6. In addition, during the tire repair process, the surface of the tire repair filler 6 is coated with lubricating oil, which can make the tire repair filler 6 more smoothly detach from the guide channel 22 to complete the tire repair operation.

[0030] As described above, when the pin 5 is in the first position, the distance between the pushing end 433 of the pushing device and the guide outlet 21 is at its maximum, providing sufficient installation space for the tire repair filler 6. When the pin 5 is in the second position, the pushing device pushes the tire repair filler 6 out of the guide opening through the guide channel 22. The front end of the tire repair filler 6 is pushed into the air leak hole, and a part remains in the guide channel 22. At this time, the guide head 2 is pulled out, exposing a part of the tire repair filler 6 outside the air leak hole. The user only needs to trim the part outside the air leak hole to complete the repair, ensuring that the tire repair filler 6 has sufficient depth to be filled into the tire air leak hole, forming an effective sealing repair.

[0031] In this embodiment, the pushing device further includes a push rod 42 and a top rod 43. The pin 5 is connected to the top rod 43. The front end of the push rod 42 abuts against the rear end of the top rod 43. The push rod 42 is used to connect with an external driving component to drive the push rod 42 to slide within the mounting channel 11, thereby pushing the top rod 43 to move the pin 5.

[0032] Specifically, such as Figure 7 as well as Figure 9 As shown, the pin 5 is provided with a first connecting part 51, and the push rod 43 is provided with a second connecting part 41. The first connecting part 51 and the second connecting part 41 are connected to connect the pin 5 and the push rod 43. Preferably, the first connecting part 51 is an external thread, and the second connecting part 41 is a threaded hole. The threaded connection provides a stable and reliable connection between the pin 5 and the push rod 43. At the same time, the threaded connection facilitates disassembly and assembly. When not in use, the user can remove the pin 5 from the push rod 43 for storage and easy carrying.

[0033] As a preferred option, such as Figure 7 As shown, the pin 5 includes a connecting end 52 and a limiting end 53. The connecting end 52 is provided with a first connecting part 51. The limiting end 53 is connected to the connecting end 52 and passes through the limiting groove 12. The push rod 43 slides to drive the pin 5 to move within the limiting groove 12. The limiting end 53 is connected to the connecting end 52 and extends outward from the limiting groove 12 to form a handle end 54. Through the above structure, the cooperation between the limiting end 53 and the limiting groove 12 limits the movement range of the pushing device, that is, it only moves between the first position and the second position, avoiding excessive pushing distance of the push rod 43, which would cause the tire patch filler 6 to be over-compressed and damaged, thus improving the efficiency of the tire repair operation and keeping the tire patch filler 6 intact during the pushing process, thereby improving the reliability of the tire repair operation. In addition, the handle end 54 can provide an additional force point to assist the user in quickly and easily removing the guide head 2 from the tire.

[0034] Preferably, the lateral width of the limiting end 53 is not less than the lateral width of the connecting end 53. A wider limiting end 52 can provide a larger contact area, making it easier for the user to grasp.

[0035] In this embodiment, as Figure 8 As shown, a first limiting protrusion 434 is provided on the side wall of the top rod 43, and a second limiting protrusion 112 is provided on the inner wall surface of the mounting channel 11. The first limiting protrusion 434 abuts against the second limiting protrusion 112, so that the top rod 43 is kept installed in the mounting channel 11 to prevent loosening.

[0036] Specifically, such as Figure 9 As shown, the push rod 43 has a first part 431 and a second part 432 connected to the first part 431. The push end 433 is disposed in the first part 431. The first limiting protrusion 434 is disposed between the first part 431 and the second part 432. The lateral width of the first part 431 is smaller than the lateral width of the second part 432. The first limiting protrusion 434 abuts against the second limiting protrusion 112 to prevent the push rod 43 from shaking in the mounting channel 11.

[0037] In this embodiment, as Figure 3 and Figure 4 As shown, the rear end of the push rod 42 is provided with a drive input end 421, which is used to connect with an external drive component. This allows the push rod 42 to rotate and move under the drive of the external drive component, thereby pushing the top rod 43 to slide within the mounting channel 11. By connecting to an external drive component to provide rotational power to push the top rod 43 to slide within the mounting channel 11, the user can complete the insertion of the tire repair filler 6 without relying on manual force, thus improving the efficiency of the tire repair operation.

[0038] Specifically, the outer wall of the push rod 42 is provided with a first threaded portion 422, and the inner wall of the mounting channel 11 is provided with a second threaded portion 111. The first threaded portion 422 and the second threaded portion 111 cooperate to allow the push rod 42 to rotate and move under the driving action of the external drive component, thereby pushing the top rod 43 to slide within the mounting channel 11. Through the cooperation of the first threaded portion 422 and the second threaded portion 111, the push rod 42 can move smoothly along the mounting channel 11 when rotating, avoiding jamming caused by uneven friction or sliding, ensuring a stable and reliable transmission process. At the same time, the threaded transmission can control the movement distance of the top rod 43 by controlling the rotation angle, thereby precisely controlling the pushing distance of the tire repair filler 6. In addition, the threaded structure also has a self-locking ability to prevent the push rod 42 from accidentally retracting, ensuring that the tire repair filler 6 can maintain a stable position after being pushed in, thus improving the sealing and safety of the tire repair.

[0039] Preferably, the drive input end 421 is a hexagonal screw hole, and the external drive component is a hexagonal screw that matches the hexagonal screw hole. The connection between the screw hole and the screw is simple in structure, and users can quickly complete the assembly and disassembly, which is convenient for replacement in different scenarios and improves the versatility and convenience of the tool.

[0040] In this embodiment, as Figure 4 As shown, the main body 1 has a first opening 13 and a second opening 14 that extend through the front and rear ends, respectively. The first opening 13 extends into the guide head 2, connecting the mounting channel 11 and the guide channel 22. The second opening 14 allows an external drive component to enter the mounting channel 11 and connect to the drive input end 421 of the push rod 42. This structure allows the external drive component to be quickly connected to the push rod 42 for repairing tire punctures.

[0041] According to the above structure, the push rod 42 provides a rotational driving force to push the top rod 43 to slide within the installation channel 11, thereby pushing the tire repair filler 6 in the installation channel 11 to move. By setting the pin 5, the top rod 43 is prevented from rotating within the installation channel 11, so that the top rod 43 always maintains a linear movement within the installation channel. This avoids the top rod 43 and the push rod 42 rotating together to drive the tire repair filler 6 to rotate when the tire repair filler 6 is pushed in, thereby preventing torsional damage to the tire repair filler 6 and effectively improving the reliability and durability of the tire repair filler 6.

[0042] In this embodiment, as Figure 3 as well as Figure 4 As shown, the tire repair tool 100 also includes a probe 3, which is detachably disposed within the guide channel 22. The front end of the probe 3 extends out of the guide channel 22 through the guide outlet 21. The probe 3 is used to guide at least a portion of the guide head 2 and the guide outlet 21 into the tire's puncture hole. By using the probe 3 to insert the guide head 2 into the tire's puncture hole, the user can easily and quickly align the puncture hole, reducing the difficulty of operation.

[0043] In this embodiment, as Figures 3-4 as well as Figure 10 As shown, the guide head 2 includes a guide sleeve 24 and a guide nozzle 25 disposed at the front end of the guide sleeve 24. The guide sleeve 24 has a first channel 241, the guide nozzle 25 has a second channel 251, and the guide outlet 21 is disposed at the front end of the guide nozzle 25. The first channel 241 and the second channel 251 are connected to form a guide channel 22. The lateral width of the first channel 241 gradually decreases from top to bottom. Through the above structure, the tire patch filler 6 is made to fit against the inner wall of the first channel 241, so that it can be pushed more smoothly when it enters the guide channel 22, avoiding jamming or squeezing that could cause deformation or damage to the tire patch filler 6.

[0044] In this embodiment, the length of the guide nozzle 25 is 1mm-20mm. Preferably, the length of the guide nozzle 25 in this embodiment is 6mm-18mm.

[0045] In this embodiment, as Figure 4 as well as Figure 11 As shown, the probe 3 includes, from bottom to top, a tip portion 31, a connecting portion 32, an extension portion 33, and an extension portion 34. The tip portion 31, the connecting portion 32, the extension portion 33, and the extension portion 34 are interconnected. The tip portion 31 is used to insert into the air leak hole of the tire. The connecting portion 32 is located in the second channel 251. The extension portion 33 is disposed in the first channel 241. The extension portion 34 extends into the mounting channel 11. The extension portion 33 has a guide outer wall surface 331. The first channel 241 has a guide inner wall surface 242. The guide outer wall surface 331 contacts the guide inner wall surface 242. The guide outer wall surface 331 is a conical guide outer wall surface 331, and the guide inner wall surface 242 is a conical guide inner wall surface 242.

[0046] In this embodiment, a handle groove 341 is provided on the side wall of the extension portion 34. The handle groove 341 is used to allow the user to remove the probe 3 from the guide channel 22. The extension portion 34 is used to press and install the tire repair filler 6 into the installation channel 11. The end face of the extension portion 34 is also provided with a positioning guide groove 342. The positioning guide groove 342 is used to contact the tire repair filler 6, so that the tire repair filler 6 is positioned and pressed into the installation channel 11. The positioning guide groove 342 can ensure that the tire repair filler 6 enters the installation channel 11 in a vertical direction, so that the tire repair filler 6 enters the installation channel evenly, avoiding the tire repair filler 6 from being twisted or excessively squeezed during the installation process, thereby ensuring that the subsequent tire repair operation is more accurate and reliable.

[0047] Preferably, the hardness of the probe 3 is greater than that of the guide head 2. The outer wall surface of the connecting part 32 of the probe 3 fits against the inner wall surface of the second channel 251 to prevent the guide nozzle 25 from deforming. The tapered guide outer wall surface 331 of the extension part 33 contacts the tapered guide inner wall surface 242 of the first channel 241. Through the tapered surface fit, the probe 3 and the guide head 2 always remain coaxial. Thus, in the subsequent tire repair process, when the tire repair filler 6 passes through the guide channel 22, its path is completely consistent with the direction of the air leak hole, avoiding the tire repair filler 6 being squeezed or worn at the guide outlet 21 due to angular deviation.

[0048] In this embodiment, as Figure 11 as well as Figure 12 As shown, a first limiting part 35 is provided between the extension part 33 and the extension part 34, and a second limiting part 113 is provided on the inner wall of the front end of the installation channel 11. When the guide head 2 is connected to the main body 1, the first limiting part 35 and the second limiting part 113 abut against each other, so that the probe 3 is limited to be installed in the installation channel 11. When the guide head 2 is separated from the main body 1, the extension part 34 is used to push the tire repair filler 6 to be installed in the installation channel 11, and the first limiting part 35 and the second limiting part 113 abut against each other to limit the length of the probe 3 entering the installation channel 11, thereby limiting the depth of the tire repair filler 6 entering the installation channel 11. This eliminates the need for the user to measure or judge, and only requires the probe 3 to push the tire repair filler 6 into the installation channel 11. The tire repair filler 6 can then be accurately inserted into the preset depth of the installation channel 11. This allows the tire repair filler 6 to have a smaller pushing stroke during the subsequent pushing process, reducing the risk of damage to the tire repair filler 6, ensuring the integrity of the tire repair filler 6 during the pushing process, and making the tire repair operation more stable and reliable.

[0049] In this embodiment, the guide head 2 is a metal guide head 2. Metal material has high mechanical strength and hardness, which can withstand the large thrust and friction generated during tire repair, and is not easily deformed or damaged, thus extending the service life of the tire repair tool.

[0050] In this embodiment, as Figure 12 As shown, a third connecting part 15 is provided on the outer side wall of the front end of the main body 1, and a fourth connecting part 23 is provided on the inner wall surface of the guide head 2. The third connecting part 15 and the fourth connecting part 23 cooperate with each other, so that the guide head 2 can be detachably connected to the front end of the main body 1. Preferably, the third connecting part 15 is internally threaded and the fourth connecting part 23 is externally threaded. The threaded connection not only provides a stable and reliable connection between the main body 1 and the guide head 2, but also enables quick assembly and disassembly between the main body 1 and the guide head 2, improving tire repair efficiency and the portability of the tire repair tool.

[0051] In this embodiment, as Figure 5 as well as Figure 14 As shown, the tire repair tool 100 also includes a tire repair filler 6. When the pushing device moves the pin 5 to the first position, the front end of the mounting channel 11 has a receiving space 114 for accommodating the tire repair filler 6. The tire repair filler 6 is disposed in the receiving space 114. When the pushing device moves the pin 5 to the second position, the pushing device pushes the tire repair filler 6 to move linearly from the mounting channel 11 to the guide channel 22, and at least a portion of the tire repair filler 6 passes through the guide channel 22 and extends from the guide outlet 21 into the tire interior to repair the tire puncture.

[0052] In this embodiment, the tire repair filler 6 is an elastic tire repair filler 6. The elastic tire repair filler 6 in this embodiment not only has excellent wear and corrosion resistance, but also excellent elasticity and sealing performance. At the same time, its material has an affinity similar to natural rubber, is highly compatible with tire materials, and can gradually fuse with the tire after long-term use to form a durable and stable sealing effect.

[0053] In this embodiment, as Figures 13-14 As shown, the tire repair filler 6 includes a rod 61 and an umbrella-shaped cap 62 disposed at the front end of the rod 61. The diameter of the umbrella-shaped cap 62 is larger than the diameter of the mounting channel 11 and the guide channel 22. The pushing device pushes the umbrella-shaped cap 62 and the rod 61 of the tire repair filler 6 to move sequentially from the mounting channel 11 into the guide channel 22. The rod 61 is disposed at the front end of the mounting channel 11. The umbrella-shaped cap 62, which is exposed outside the mounting channel 11, is pushed into the mounting channel 11 through the first opening 13 of the main body 1 by the probe 3. When the pushing device drives the pin 5 to move to the second position, the pushing device pushes the tire repair filler 6 to move linearly from the mounting channel 11 into the guide channel 22. The umbrella-shaped cap 62 and part of the rod 61 of the tire repair filler 6 pass through the guide channel 22. After the umbrella-shaped cap 62 passes through the guide outlet 21, it unfolds and opens so that the umbrella-shaped cap 62 fits the inner wall surface of the tire puncture hole.

[0054] In this embodiment, the umbrella-shaped cap 62 includes a guide surface 621 and a stop surface 622 opposite to the guide surface 621. The guide surface 621 is an arc-shaped guide surface 621, and the stop surface 622 is used to cover the inner wall surface of the tire puncture hole. When the umbrella-shaped cap 62 is pushed into the guide channel 22, the arc-shaped guide surface 621 can better fit the conical inner surface of the first channel 241, thus making the insertion process of the tire patch filler 6 smoother. Furthermore, when the umbrella-shaped cap 62 is pushed into the tire, it can unfold inside the tire, and the stop surface 622 can fit against the inner wall of the tire, forming a large area of ​​coverage, thereby improving the sealing effect.

[0055] In this embodiment, the stop surface 622 and the rod 61 are angled together. The rod 61 includes a first end 611 and a second end 612 opposite to the first end 611. The first end 611 is connected to the umbrella-shaped cap 62, and the lateral width of the rod 61 gradually increases from the first end 611 to the second end 612. With this structure, when the tire patch filler 6 is pushed into the puncture hole of the tire, the tire pressure inside the tire can tightly press the stop surface 622 of the umbrella-shaped cap 62 against the inner wall of the tire. Simultaneously, the tapered design of the rod 61, with its lateral width gradually increasing from top to bottom, can form a double-sealing structure with the umbrella-shaped cap 62 under the tire pressure inside the tire, making the tire repair operation more reliable. The angle between the stop surface 622 and the rod 61 ranges from 0° to 90°, and the taper of the rod 61 ranges from 1% to 20%. Preferably, the taper of the rod 61 is 11.3%.

[0056] In this embodiment, the rear end of the rod 61 is also provided with an abutment groove 63, which abuts against the front end of the pushing device, causing the pushing device to push the tire repair filler 6 toward the guide channel 22 of the guide head 2, and enter the inner side of the tire puncture hole from the guide outlet 21 to repair the tire puncture hole. The abutment groove 63 provides a force-bearing contact surface between the pushing device and the tire repair filler 6, so that the pushing force can be stably and evenly transmitted to the tire repair filler 6.

[0057] The method of using the tire repair tool of the present invention for repair is as follows:

[0058] First, clean the foreign objects from the surface of the tire's puncture hole, and then use a hole enlarger to clean and enlarge the puncture hole.

[0059] After the probe 3 is installed in the guide channel 22 of the guide head 2, the guide head 2 is connected to the main body 1, and then the probe 3 guides the guide nozzle 25 of the guide head 2 to be inserted into the air leak hole of the tire through the main body 1.

[0060] Remove the main body 1 from the guide head 2, leaving the guide head 2 in the tire puncture hole, and remove the probe 3 from the guide channel 22.

[0061] Move pin 5 to the first position and slide top rod 43 upward in the mounting channel 11 to make room 114 for mounting the tire patch filler 6. Reconnect the main body 1 to the guide head 2 left on the tire. At the same time, connect the external drive to the drive input end 421 of the push rod 42. Driven by the external drive, push rod 42 drives top rod 43 to move linearly in the mounting channel 11. At the same time, top rod 43 pushes the tire patch filler 6 from the mounting channel 11 to the guide channel 22 and pushes it into the tire puncture hole from the guide outlet 21. When top rod 43 moves pin 5 to the second position, stop applying driving force to the external drive.

[0062] Apply a directional driving force to the external drive component to move the push rod 42 away from the push rod 43. At this time, the push rod 43 releases the pressure on the tire filler 6.

[0063] Remove the guide head 2 from the tire, adjust the position of the tire patch filler 6 so that it fully expands inside the tire and adheres tightly to the inner wall, and trim the portion of the tire patch filler 6 exposed on the outside of the tire so that the weight of the portion of the tire patch filler 6 remaining in the tire puncture hole is less than 10 grams. Preferably, in this embodiment, the weight of the portion of the tire patch filler 6 remaining in the tire puncture hole is less than 5 grams, ensuring that the tire can still maintain a relatively balanced state after the tire is repaired.

[0064] The tire repair tool 100 of the present invention can repair tire puncture holes with a diameter of less than 10 mm. In this embodiment, the tire repair tool 100 is preferably able to repair tire puncture holes with a diameter of less than 6.8 mm.

[0065] The above descriptions provide one or more embodiments in conjunction with specific details, but do not imply that the specific implementation of the present invention is limited to these descriptions. Any methods or structures that are similar to or identical to those of the present invention, or any technical deductions or substitutions made based on the concept of the present invention, should be considered within the scope of protection of the present invention.
