Technical Field

[0001] This utility model relates to the field of tire repair technology, specifically to a tire repair tool that assists in inserting a tire repair strip into a tire. Background Technology

[0002] In the field of tire repair, using tire repair strips is a common and effective method. Existing tire repair strip tools typically include a handle, a needle, and a rubber strip (tire repair strip). For example, patent document CN2830048Y describes a special needle for tire repair using tire repair strips. This needle is threaded through a needle hole onto the rubber strip, and then inserted into the tire from the outside of the leak hole. After penetrating the tire, the needle is pulled back out and the rubber strip is cut along the tire's outer surface. While this method can effectively seal small holes in tires, it has certain limitations in practical operation. Specifically: Pushrod insertion difficulty: The pushrod in the current design requires a lot of force to enter the tire, especially when dealing with tires made of thicker or harder materials.

[0003] Reliance on additional tools: Assistive tools are required to help the push rod smoothly enter the tire, which increases the complexity of operation and preparation time. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a tire repair tool that assists in squeezing the tire repair strip into the tire. The purpose is to solve the problems of difficulty in pushing the push rod and reliance on additional tools in traditional tools, making the tire repair process simpler, faster and more efficient.

[0005] This utility model is achieved through the following technical solution: a tire repair tool for assisting in inserting a tire repair strip into a tire, comprising a needle rod for inserting the tire repair strip into the tire, characterized in that: a push rod is fixedly provided at the rear end of the needle rod, the push rod being slidably disposed on the tool body; a main body opening is provided at the center of the tool body; the push rod passes horizontally through the tool body from back to front, and simultaneously passes through the main body opening; a push plate spring is provided inside the main body opening and slidably fitted on the push rod; tying strap connecting rings are symmetrically fixed at the front of the tool body; tying straps are connected to the tying strap connecting rings, and the two ends of the tying straps are respectively fixedly connected to two upper and lower tying straps. A connecting ring; a buckle for splitting or connecting the strap is provided on the strap; a handle is fixedly provided at the lower part of the tool body; a grip is hinged at the lower part of the tool body opposite to the handle; a locking pin is fixedly provided at the upper part of the grip; a push plate is provided between the push plate spring and the locking pin and is slidably fitted on the push rod; a locking plate is fitted at the rear of the push rod to prevent the push rod from moving backward; a protrusion is fixedly provided at the rear of the tool body, and a limiting boss is fixedly provided on the protrusion to prevent the upper part of the locking plate from moving back and forth; a limiting spring is provided between the locking plate and the tool body and is slidably fitted on the push rod; the needle bar is fixedly provided at the front end of the push rod.

[0006] Furthermore, a stop tube is fixedly installed at the rear end of the push rod to prevent the push rod from moving forward.

[0007] Furthermore, a groove is provided at the rear of the grip to prevent interference between the grip and the handle.

[0008] Furthermore, the push rod has a hexagonal cross-section; the tool body, the clamping plate, and the push plate are provided with hexagonal through holes for the push rod to pass through, and the diameter of the hexagonal through holes is larger than the diameter of the push rod.

[0009] Furthermore, the front end of the needle bar is provided with a needle hole for clamping the tire repair strip, and the needle hole is connected to the front end of the needle bar to form a needle hole channel for the tire repair strip to detach from the needle bar.

[0010] The beneficial effects and features of this utility model are as follows: Easier Rod Advancement: By incorporating mechanical structures such as a push plate spring, a locking plate, and a limiting spring, this invention effectively pushes the rod forward when the user grips the handle tightly. Upon releasing the grip, the push plate spring returns the push plate to its original position, while the rod cannot move backward due to friction between the locking plate and the rod, thus achieving a gradual forward movement of the rod. This design significantly reduces the force required by the operator, making the rod advancement process much easier.

[0011] No additional tools required: Traditional methods typically require additional tools to complete the entire repair process, such as auxiliary tools to help the push rod enter the tire. This invention integrates all the necessary functions into one unit, allowing for independent tire repair without relying on other tools, simplifying the operation process and saving preparation time and costs.

[0012] Improved operational stability: The system employs a strapping system, including strapping connectors, straps, and buckles, which securely binds the tire, ensuring that the tool and tire remain radially positioned. This prevents potential shifting or instability during pushrod advancement, improving the accuracy and efficiency of repairs. Attached Figure Description

Detailed Implementation

[0016] The following combination Figure 1-3 The contents of this utility model will be described in detail through specific embodiments. Example

[0017] The specific construction of this tire repair tool includes: Main structure 1: This is the basic frame of the entire tire repair tool. It has a through-hole 101 in the center to provide movement space for push rod 2, push plate spring 3, push plate 9, and locking pin 8.

[0018] Push rod 2: As the main working component, push rod 2 passes through the main body opening 101, and a needle rod 201 is fixed to its front end. The front end of the needle rod 201 has a needle hole 16 for clamping the tire repair strip 18. The needle hole 16 and the front end of the needle rod 201 are connected by a needle hole channel 17, which facilitates the removal of the tire repair strip from the needle rod. The push rod 2 has a hexagonal cross-section to ensure that it will not rotate during use, and hexagonal through holes are provided at corresponding positions on the tool body 1, the clamping plate 10, and the push plate 9 to ensure that the push rod can slide smoothly.

[0019] Spring mechanism: Includes push plate spring 3 and limit spring 13. Push plate spring 3 is located inside the main body opening and is fitted onto push rod 2, providing a restoring force to push push plate 9 back to its original position; a protrusion 11 is provided at the rear of tool body 1, on which a limit boss 12 is fixed to limit the forward and backward movement range of clamping plate 10. Limit spring 13 is located between clamping plate 10 and tool body 1, ensuring that clamping plate always applies appropriate resistance to push rod.

[0020] The strapping system includes strap connecting rings 4, straps 5, and buckles 501. The strap connecting rings 4 are symmetrically fixed to the front of the tool body 1. The two ends of the straps 5 are fixed to the two strap connecting rings 4 respectively. The buckles 501 enable quick assembly and disassembly. The straps are used to secure the tire and ensure radial positioning of the tool and the tire.

[0021] The gripping part includes a handle 6 and a grip 7. The handle 6 is fixed to the lower part of the tool body 1, and the grip 7 is hinged to its opposite position. The rear part of the grip 7 is provided with a groove 15 to avoid interference with the handle. A locking pin 8 is fixed to the upper part of the grip 7. When the grip is gripped tightly, the locking pin drives the push plate to push the push rod forward a certain distance.

[0022] Operating steps: Preparation stage: First, check whether the tire repair tools are intact. Then, select the appropriate tire repair strip 18, pass one end through the needle hole 16, and ensure that it is firmly clamped.

[0023] Positioning stage: Align the front end of the needle bar 201 vertically with the wound on the tire 19, and at the same time use the strap 5 to wrap around the tire and bind it tightly, so that the tool and the tire are in a radially limited state.

[0024] Advancement Phase: The operator repeatedly grips handle 7, each grip causing push plate 9 to move forward a short distance, thus pushing push rod 2 forward and gradually squeezing the tire repair strip into the tire. After releasing the grip, due to the action of push plate spring 3, locking pin 8 and push plate 9 return to their original positions, but due to the friction between locking plate 10 and push rod 2, the push rod will not move backward with the push plate.

[0025] Repair complete: Repeat the above steps until the tire repair strip is fully inserted into the appropriate position inside the tire. Finally, untie the strap 5 and carefully pull out the needle shank 201. During this process, the tire repair strip will detach from the needle shank through the needle hole channel 17 and finally be fixed inside the tire, completing the repair process.

[0026] Reset push rod: To reset push rod 2, simply push the lower part of the clamping plate 10 forward to contact the clamping plate 10's limit on push rod 2, and then pull push rod 2 backward by hand to return push rod 2 to its initial position.
