Description

Technical Field

[0001] This application relates to the field of tire repair tools, and more particularly to a tire repair device. Background Technology

[0002] As a core rubber component of various transportation vehicles, tires significantly reduce resistance during transport due to their special physical properties of cushioning, shock absorption, and enhanced grip, providing crucial support for efficient movement. However, because tires need to operate continuously in complex road conditions (such as gravel roads and flooded roads) and variable environments, the tire body is prone to damage from punctures, wear, or compression by foreign objects, leading to air leaks. In such cases, tire repair tools are needed for timely repair.

[0003] The core components of current mainstream tire repair tools typically include a handle for operation, a rubber strip for sealing the leak, and a vulcanizing adhesive to assist in sealing. When repairing a tire, you first need to locate the leak point, insert the tip of the handle into the puncture to open the leak hole, then evenly apply the vulcanizing adhesive to the inner wall of the leak hole, and finally clamp the rubber strip with the tip of the handle and insert it into the leak hole. The vulcanization reaction allows the rubber strip to be heated and melted, and then it will adhere tightly to the tire body, thus completing the leak sealing.

[0004] While this tire repair solution effectively solves tire leaks, the handle, rubber strip, and vulcanizing adhesive are all separately designed and must be stored and carried individually. If any one of these components is lost, the entire toolkit becomes unusable, making it difficult to meet tire repair needs promptly. Therefore, developing a highly portable tire repair device has become a critical issue that urgently needs to be addressed. Utility Model Content

[0005] The purpose of this application is to provide a tire repair device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A tire repair device for sealing a tire puncture with a rubber strip, comprising:

[0008] Handle and casing;

[0009] The cylindrical shell has an inner cavity along its axial direction, and the handle is axially movable and assembled in the inner cavity;

[0010] One end of the cylindrical shell is provided with a first opening for the first end of the handle to extend out, and the other end is provided with a second opening for the second end of the handle to extend out;

[0011] A vulcanizing agent container is disposed within the inner cavity and located on the push path of the handle. When the handle is pushed toward the tire puncture hole, the rubber strip is configured to be able to pass through further. The handle includes an operating part for performing a tire repair operation.

[0012] The distal end of the operating part is tapered and used for puncture and enlargement.

[0013] Furthermore, the operating part has a radially expanding bulge in the middle, and the adhesive strip is fixedly fitted onto the bulge.

[0014] Furthermore, a polishing part is provided between the distal end and the middle part of the operating part, and the polishing part is a plurality of protrusions provided on the surface of the handle;

[0015] There is a gap between adjacent protrusions.

[0016] Furthermore, the handle is provided with a through groove extending along its axial direction from the enlarged portion to the distal end of the operating portion.

[0017] Furthermore, the through groove includes a first groove segment near the distal end and a second groove segment located on the enlarged portion;

[0018] The first groove segment is a long and narrow strip, the second groove segment is wider than the first groove segment, and the first groove segment and the second groove segment are interconnected.

[0019] Furthermore, the handle also includes a grip portion, which is perpendicularly connected to the operating portion.

[0020] Furthermore, the cross-sectional shape of the adhesive strip is U-shaped or V-shaped.

[0021] Furthermore, the inner cavity includes a first cavity and a second cavity that are interconnected and coaxially arranged; wherein the first cavity is equipped with the operating part, and the second cavity is equipped with the vulcanizing agent container.

[0022] Furthermore, the diameter of the vulcanizing agent container is larger than the diameter of the first opening.

[0023] The technical solutions provided in this application have the following advantages compared with the prior art:

[0024] The tire repair device of this application features an integrated cylindrical shell and handle structure. The rubber strip is pre-installed on the handle, and a vulcanizing agent receiving box is set in the inner cavity of the cylindrical shell and along the handle's advancement path. This integrates the handle, rubber strip, and vulcanizing agent into a single structure. When repairing a tire, simply push the handle towards the tire puncture hole to move the rubber strip through the vulcanizing agent receiving box and carry the vulcanizing agent to seal the puncture hole. This technical solution improves the portability of the tire repair device and solves the problem that existing tire repair tools have separate designs for the handle, rubber strip, and vulcanizing agent, requiring separate storage and carrying, which can easily lead to the inability to meet tire repair needs in a timely manner due to component loss. This technical solution integrates the handle, rubber strip, and vulcanizing agent into one unit, which can meet the repair needs after a tire puncture more promptly and efficiently, and reduces the difficulty of storing and carrying tire repair tools.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0040] To address the technical problem of scattered parts in existing tire repair tools, this application provides a tire repair device that integrates all parts into one unit, thus achieving portable storage and timely fulfillment of tire repair needs.

[0041] like Figures 1 to 4 As shown, this technical solution provides a tire repair device for sealing a tire puncture hole with a rubber strip, comprising: a handle 1 and a cylindrical shell 2; the cylindrical shell 2 has an inner cavity 22 along its axial direction, and the handle 1 is axially movable and assembled in the inner cavity 22; one end of the cylindrical shell 2 has a first opening 21 for the first end of the handle 1 to extend out, and the other end has a second opening 23 for the second end of the handle 1 to extend out; a vulcanizing agent container 4 is disposed in the inner cavity 22 and located on the pushing path of the handle 1, and when the handle 1 is pushed towards the tire puncture hole, the rubber strip 3 is configured to pass through the vulcanizing agent container 4 and carry the vulcanizing agent therein.

[0042] It should be noted that in this embodiment, the first opening 21 faces the side facing the tire puncture hole, and the second opening 23 faces the end where the user holds the handle 1. The orientation of the two is determined by the function of use and is not interpreted in any other way. In this embodiment, "second end" refers to the grip part 12 of the handle 1 and "first end" refers to the operating part 11 of the handle 1. However, this definition is only applicable to this embodiment. In other usage scenarios, "first end" can also refer to the grip part 12. Therefore, "first end" and "second end" need to be determined in combination with the actual usage scenario. In addition, in this embodiment, the rubber strip 3 is pre-assembled on the handle 1. All descriptions below are based on this premise. In other usage scenarios, the rubber strip 3 can also be obtained separately from the outside and then assembled and used according to actual needs.

[0043] Specifically, when a tire leaks air, first align the end of the cylinder shell 2 with the first opening 21 with the leaking location and keep it stable. The user holds the end of the handle 1 extending from the second opening 23 of the cylinder shell 2 and pushes it forcefully towards the tire, causing the handle 1 to move axially along the inner cavity 22 of the cylinder shell 2 (the pushing direction is aligned with the tire leak hole). During the pushing process of the handle 1, its first end extending from the first opening 21 will first pass through the vulcanizing agent container 4 inside the inner cavity 22 of the cylinder shell 2 and continue to move towards the tire leak hole until the first end pierces and inserts into the leak hole. As the user continues to apply pushing force, maintaining the axial movement of the handle 1, the rubber strip 3 pre-installed on the handle 1 moves synchronously. The rubber strip 3 first completely passes through the vulcanizing agent container 4, and its outer surface is evenly coated with the vulcanizing agent in the cavity. Then, it is sent into the tire leak hole along with the handle 1. After the rubber strip 3 is completely embedded in the leak hole, stop pushing the handle 1. At this time, the vulcanizing agent on the surface of the rubber strip 3 undergoes a vulcanization reaction with the tire rubber surface, so that the rubber strip 3 is initially adhered and fixed to the inner wall of the leak hole. Finally, the user pulls handle 1 in the opposite direction to remove it from the tire puncture hole. It should be understood that because the rubber strip 3 has been tightly bonded to the tire due to the vulcanization reaction, it will not come off with handle 1. Therefore, the rubber strip 3 is ultimately firmly sealed at the tire puncture hole, thus achieving the purpose of repairing the tire leak.

[0044] This technical solution solves the problem of traditional tire repair tools requiring separate storage of the handle 1, rubber strip 3, and vulcanizing agent, which can easily lead to failure to repair a tire due to the omission of a component. The tire repair device in this solution integrates the handle 1, pre-installed rubber strip 3, and vulcanizing agent container 4 into a single unit within the inner cavity 22 of the casing 2. All essential tire repair components no longer need to be carried separately. Whether for in-vehicle emergencies or outdoor travel, only this one device needs to be stored, significantly reducing the complexity of carrying and storage. Simultaneously, the integrated structure eliminates the tedious steps of finding the rubber strip 3, opening the vulcanizing agent, and manually applying it during traditional tire repair. Pushing the handle 1 simultaneously completes the crucial action of the rubber strip 3 picking up the vulcanizing agent and inserting it into the leak, avoiding operational interruptions caused by component separation. This significantly shortens tire repair time and improves operational efficiency in emergency tire repair scenarios. Furthermore, the vulcanizing agent is sealed within the container cavity of the casing 2, effectively solving the leakage and deterioration problems caused by packaging damage in traditional separate vulcanizing agents. In addition, pre-installing the rubber strip 3 on the handle 1 avoids the risk of loss and further ensures the reliability of the tire repair tool.

[0045] In one specific embodiment, the handle 1 includes an operating part 11 for performing tire repair operations; the distal end 111 of the operating part 11 is tapered for puncture and enlargement.

[0046] It should be understood that when the handle 1 is pushed toward the tire puncture hole, the distal end 111 of the operating part 11 is conical. Due to its small cross-sectional area, the force is concentrated, thus it can easily overcome the resistance of the tire and better penetrate the puncture hole.

[0047] As the handle 1 continues to advance, the punctured distal cone 111, along with the operating part 11, penetrates deeper into the vent hole. Because the cone's profile gradually increases in cross-sectional area from tip to root, the sidewalls of the cone naturally contact the inner wall of the vent hole during penetration, slowly squeezing and widening the vent hole's diameter through the pushing force. Once the vent hole is enlarged, continuing to push the handle 1 allows the rubber strip 3, subsequently used for tire repair, to smoothly enter the vent hole along the channel created by the distal cone 111, without needing to overcome any additional obstruction to achieve tire repair.

[0048] Furthermore, in order to make it easier for the adhesive strip 3 to enter the air leakage hole, the operating part 11 is provided with a radially expanding bulge 13 in the middle, and the adhesive strip 3 is fixedly fitted on the bulge 13.

[0049] As the handle 1 continues to advance until the enlarged portion 13 in the middle of the operating section 11 moves to the air vent position, the radial expansion structure of the enlarged portion 13 further expands the air vent. Compared to the initial enlargement of the air vent by the tapered distal end 111, the enlarged portion 13 enlarges the vent by a larger margin, pre-reserving a matching aperture for the insertion of the adhesive strip 3. Furthermore, the adhesive strip 3 is mounted on the enlarged portion 13, avoiding the need for a separate adhesive strip tool as in the prior art.

[0050] Furthermore, after a tire is punctured, the wall of the puncture hole is exposed to air, and impurities and dust usually adhere to the hole wall and its surrounding area. These impurities and dust directly affect the adhesion and sealing between the subsequent rubber strip 3 and the puncture hole wall. In existing tire repair processes, to solve this problem, a pre-treatment step is usually added before inflating the tire: using grinding tools (such as a special tire tread grinding head, fine sandpaper assembly, etc.) to grind the puncture hole wall and surrounding area. The purpose is to remove the attached impurities and dust and grind the puncture hole wall to a smooth and flat state, creating conditions for a tight fit between the subsequent rubber strip 3 and the hole wall. However, this treatment method requires carrying additional grinding tools, which is inconvenient for the user.

[0051] In this regard, such as Figure 3 and Figure 4 As shown, the tire repair device of this technical solution has a grinding part 14 between the far end 111 and the middle part of the operating part 11. The grinding part 14 consists of a plurality of protrusions 141 provided on the surface of the handle 1; there is a gap 142 between adjacent protrusions 141.

[0052] It should be understood that with this design, in conjunction with the front conical distal end 111 to puncture and enlarge the air leakage hole, the grinding part 14 grinds the air leakage hole. That is, the tire repair device of this technical solution has a design that integrates multiple functions of "puncture-expansion-grinding".

[0053] In use, when the handle 1 pushes the operating part 11 toward the vent hole, the conical distal end 111 first completes the piercing and initial venting. Then, the grinding part 14 on the operating part 11 enters the vent hole with the pushing motion. The protrusions 141 of the grinding part 14 can directly contact the impurities (dust, gravel, rubber debris, etc.) attached to the vent hole wall. During continuous pushing, the protrusions 141 scrape the impurities off the hole wall through a scraping action. Simultaneously, the friction between the protrusions 141 and the hole wall provides initial polishing, making the hole wall smoother. This design eliminates the need for additional grinding tools, integrating the grinding action into the continuous "piercing-venting" process. This saves on the separate grinding step, improves tire repair efficiency, and ensures a tight fit between the subsequent rubber strip 3 and the hole wall by promptly cleaning impurities, preventing sealing failure due to impurity residue.

[0054] Furthermore, the design of the gap 142 between adjacent protrusions 141 allows the grinding part 14 to naturally trap some vulcanizing agent when passing through the vulcanizing agent container 4. In the subsequent tire repair process, when the rubber strip 3 is peeled off from the bulge 13 of the handle 1 and is about to enter the vent hole, the vulcanizing agent remaining in the gap 142 will be transferred and adhered to the surface of the rubber strip 3 as the rubber strip 3 is peeled off.

[0055] When the rubber strip 3 with the vulcanizing agent is inserted into the vent hole, the vulcanizing agent on the surface of the rubber strip 3 will come into full contact with the vent hole wall and undergo a vulcanization reaction. This design not only enhances the adhesiveness and structural stability of the rubber strip 3, but also allows the rubber strip 3 to form a tight chemical bond with the vent hole wall, eliminating the tiny gaps between the rubber strip 3 and the hole wall, ensuring the sealing fit at the joint between the rubber strip 3 and the hole wall, and guaranteeing the vent-proof effect after tire repair.

[0056] Furthermore, to facilitate the peeling of the adhesive strip 3 from the handle 1, the handle 1 is provided with a through groove 15 extending axially from the enlarged portion 13 to the distal end 111 of the operating portion 11. The through groove 15 includes a first groove segment 151 located on the distal end 111 and a second groove segment 152 located on the enlarged portion 13; the first groove segment 151 is a narrow strip, and the width of the second groove segment 152 is greater than that of the first groove segment 151, and the first groove segment 151 and the second groove segment 152 are interconnected.

[0057] In use, the adhesive strip 3 is pre-fixed and fitted into the second groove section 152 of the enlarged portion 13. When the operating part 11 is advanced to the enlarged portion 13 and enters the air vent, and the adhesive strip 3 needs to be peeled off: First, the second groove section 152 of the enlarged portion 13, being wider, provides sufficient "release space" for the initial peeling of the adhesive strip 3. When the operator applies force in the peeling direction, the adhesive strip 3 will move along the second groove section 152 towards the first groove section 151 of the through groove 15. The first groove section 151 is designed as a narrow strip, forming a "directional constraint" on the adhesive strip 3, preventing the adhesive strip 3 from shifting or twisting during the peeling process. Finally, the adhesive strip 3 will smoothly peel off from the handle 1 and accurately enter the air vent along the continuous channel from the wide second groove section 152 to the narrow first groove section 151. It should be understood that the design of the through groove 15 provides a guiding channel for the movement trajectory of the adhesive strip 3 during the peeling process from the enlarged portion 13 to the air vent. In particular, the narrow design of the first groove 151 can effectively prevent the adhesive strip 3 from peeling off prematurely before reaching the air leakage hole.

[0058] Furthermore, in order to make it easier for users to operate the tire repair device and make it less strenuous to use, the handle 1 also includes a grip part 12, which is vertically connected to the operating part 11.

[0059] It should be understood that the vertical connection between the grip 12 and the operating part 11 provides a stable "support fulcrum" for the hand. When the user grips the grip 12, the hand is less likely to deviate due to force, and the user can more accurately control the direction of the operation part 11. This avoids the operation part 11 deviating from the air leakage hole due to hand shaking, and ensures that the puncture and hole enlargement actions are accurate and in place.

[0060] In one specific embodiment, the cross-sectional shape of the adhesive strip 3 is U-shaped or V-shaped. For example... Figure 2 As shown, in this tire repair device, for example, a U-shaped rubber strip 3 is conveniently clamped in the second groove 152. During the tire repair process, when the handle 1 is applied force and the operating part 11 is pushed into the puncture hole, and it is necessary to pull the operating part 11 out of the puncture hole, the user rotates the handle 1 to allow the rubber strip 3 to slide along the second groove 152 into the first groove 151, and finally peel off from the distal conical end 111. During the peeling process, the opening of the U-shaped rubber strip 3 gradually turns to the opposite direction of the pull-out direction, thereby reducing the peeling resistance and making it easier for the rubber strip 3 to detach from the handle 1. At the same time, the portion of the rubber strip 3 opposite to its opening direction is twisted and contracted under the action of rotational force, forming a dense clump structure. This clump structure can tightly fill the puncture hole, effectively blocking the damaged area and achieving a reliable seal, thereby improving the tire repair effect and reliability.

[0061] In addition, the inner cavity 22 of the shell 2 includes a first cavity 221 and a second cavity 222 that are interconnected and coaxially arranged; wherein, the first cavity 221 is equipped with an operating part 11, and the second cavity 222 is equipped with a vulcanizing agent container 4.

[0062] It should be understood that this design, on the one hand, ensures that the "coaxial arrangement" places the operating part 11 and the vulcanizing agent container 4 on the same axis. When the operating part 11 is advanced, it can evenly pass over the vulcanizing agent container 4 in the second cavity 222 along the axis, ensuring that the surface of the operating part 11 stably carries the vulcanizing agent and avoids uneven application of the vulcanizing agent due to axis misalignment, thus providing a uniform agent base for the subsequent vulcanization and bonding of the rubber strip 3 with the air leakage hole. On the other hand, the "interconnected" structure eliminates the need for an additional vulcanizing agent transmission channel, allowing the vulcanizing agent to directly contact the operating part from the second cavity 222. The distal end 111 and the grinding part 14 of 11 simplify the overall structure and reduce the resistance when the operating part 11 is pushed forward, making the piercing and hole enlarging actions smoother. In addition, the functional partition design of the first cavity 221 dedicated to assembling the operating part 11 and the second cavity 222 dedicated to storing the vulcanizing agent not only ensures the stability of the operating part 11 after assembly (avoiding shaking during advancement), but also allows sufficient vulcanizing agent to be stored in the independent space of the second cavity 222 without frequent replenishment. At the same time, the coaxial structure greatly reduces the radial dimension of the device, making the whole device smaller and more portable.

[0063] In addition, the diameter of the vulcanizing agent container 4 is larger than the diameter of the first opening 21. It should be understood that this design, with the diameter of the first opening 21 being smaller than the diameter of the vulcanizing agent container 4, can constrain the vulcanizing agent container 4, so that when the handle 1 is pushed in the direction of the tire puncture hole, the vulcanizing agent container 4 is prevented from detaching from the first opening 21 and falling outside the tire repair device.

[0064] In summary, the tire repair device of this technical solution integrates multiple functions such as "puncture-expansion-grinding-further expansion-rubber strip detachment-sealing" into one unit, effectively solving the problem that existing technologies require carrying multiple tools to repair tires, making the operation cumbersome and inconvenient. The tire repair device of this technical solution completes the repair process in one go, eliminating the need for multiple tools and simplifying operation.
