This application claims the priorities of Chinese patent application number 201510755168.8, filed on Nov. 5, 2015, and of Chinese patent application number 201620532585.6, filed on May 27, 2016, the entire contents of which are incorporated herein by reference.
The present invention belongs to the technical field of tire repairing and in particular, relates to a quick tire repairing nail and an using method thereof.
In daily life, the conventional human-powered transport has been replaced by transportation tools. The transportation tools comprise various transport machines, including automobiles and motorcycles, and all of these transportation tools have a plurality of tires. For example, when driving, an automobile will often encounter a situation in which the tire is punctured by sharp objects on the road, thereby causing a flat tire, and the punctured hole of the tire must be repaired. The most traditional method for repairing a tire is cold or hot tire repairing, wherein a rubber piece is pasted onto the inner surface of the tire where the punctured position is located to block the punctured hole and these repairing methods can be executed only by professional technicians at a tire repairing place, which not only takes a long repairing time but also needs specialized tire disassembling devices.
In addition, useful patents of CN88203970 and CN201320552797.7 use a rubber nail for repairing tire and a tire puncture wound repairing component with self-sealing layer receptively. The two tire repairing methods are substantially identical, comprising a tire repairing nail for sealing a puncture wound, and a rubber piece adhered to the puncture wound and used for sealing and fixing the tire repairing nail, wherein the tire repairing nail comprises a nail cap and a nail body, one end of the nail body and the nail cap are fixed, and the diameter of the rubber piece is greater than that of the nail cap. When in use, the tire is disassembled from the wheel rim, the nail body of the tire repairing nail is pushed into the puncture wounds from the inside of the tire and then one side of the rubber piece is adhered to the self-sealing layer of the tire, making the rubber piece cover the nail cap and the puncture wounds to implement the tire repairing.
No matter whether it is cold or hot tire repairing or the two disclosed patented technologies of tire repairing, the wheel needing to be repaired must be disassembled from a vehicle and tire repairing can be done only after the tire has been removed by a specialized tire removing tool from the wheel rim, which needs a very long time and professional tools as well as people to complete, thereby bringing great troubles to tire repairing. In addition, during the removing and installing of the tires, the surface of the wheel rim is susceptible to damage, such as scratches, influencing the artistic appearance of the automobile, especially high-end vehicles. Furthermore, even if these puncture wounds have been repaired in the inner wall of the tire, but the puncture wounds on the outer surface of the tire are expose and will be embedded by foreign matters such as rocks or intruded by water when in use, influencing the repairing firmness and causing air leakage phenomenon to easily occur to the puncture wounds again.
The object of the present invention, directed to the above problems, is to provide a quick tire repairing nail that is more reasonably designed and may conveniently, easily and quickly repair a tire.
Another object of the present invention, directed to the above problems, is to provide a method for using the quick tire repairing screw with an easy operation and a quick tire repairing speed.
To reach the above objects, the present invention adopts following technical scheme: the quick tire repairing nail comprises a tire repairing screw made of hard materials, wherein the front end of the tire repairing screw is provided with a sharp portion and the rear end of the tire repairing screw is provided with a screw head. The end of the screw head far away from the tire repairing screw is provided with a concave-convex matching structure matched with the tool for rotating the screw. The tire repairing nail further comprises a sealing sleeve wrapping the outside of the screw head and/or the outside of the tire repairing screw. The sealing sleeve is made of soft materials and the sealing sleeve has a taper structure with a small front end and a big rear end. The sealing sleeve deforms under a radial extrusion force, thereby blocking the puncture wounds, wherein the sealing sleeve is sealed against the puncture wounds and the sealing sleeve is tightly coupled to the screw head and/or the tire repairing screw. Thus, air leakage phenomenon is avoided. Of course, the sealing sleeve may sleeve the whole tire repairing screw and the tire repairing screw, the sharp portion and the screw head are connected as an unitary structure. The tool comprises any one of the screw driver, the polygonal wrench and the socket.
The tire repairing screw further includes at least one air checking ring at the end approaching to the screw head, the outer diameter of the air checking ring is less than or equal to or more than that of the screw head. When there are multiple air checking rings, the outer diameter of the air checking rings are same or gradually narrowing from the screw head to the sharp portion. The air checking ring nearest to the screw head forms an annular positioning slot with the screw head, thereby avoiding the falling out of the sealing sleeve and the tire repairing screw. And, the rubber of the tire can be intruded into the annular positioning slot.
The sealing sleeve sleeves the outside of the air checking ring, and an oriented angular surface slanting towards the sharp portion is formed on the outer wall of the air checking ring. The sealing sleeve seals the air checking ring.
The outer wall of the screw head is provided with an outer annular conical surface slanting towards the tire repairing screw, and the end of the sealing sleeve nearing the screw head is provided with an inner annular conical surface matched with the outer annular conical surface.
The outer annular conical surface and/or the oriented angular surface is provided with a plurality of annular protrusions with a gradually narrowing outer diameter and each two adjacent annular protrusions are connected or spaced. The screw head and the annular protrusions are connected as an unitary structure. The annular protrusion includes an arc or acuminate convex.
The sealing sleeve is injection molded and firmly embeds the tire repairing screw, the screw head and the air checking ring; or the sealing sleeve is a soft band coiling around the tire repairing screw, the screw head and the air checking ring. If the sealing sleeve is injection molded, some internal spiral grooves are formed corresponding to the threads of the tire repairing screw.
A plurality of threads are exposed on the sharp portion, and a corresponding front end portion of the sealing sleeve is smoothly transited to the exposed threads; and the thread of the tire repairing screw is arranged with a position limiting structure for preventing the tire repairing screw from rotating in the direction opposite to the screwing-in direction of the tire repairing screw. The concave-convex matching structure is a cross recess or a straight slot or a concave multi-arris recess or other shape structures. The diameter of the big head end of the sealing sleeve is equal to or less than the outer diameter of the screw head.
An outer wall of the sealing sleeve is an annular conical surface, to be swimmingly intruded into the puncture wounds.
As another embodiment, an outer wall of a front end of the sealing sleeve is provided with spiral protrusions corresponding to the threads on the tire repairing screw, and a rear end of the sealing sleeve is provided with at least one annular protrusion corresponding to the air checking ring. An annular positioning slot is formed on the outer wall of the sealing sleeve nearby the annular protrusion. The annular protrusion and the annular protrusion is capable of improving the structural strength after intruding the tire repairing screw to the puncture wounds, thereby avoiding the falling out of the sealing sleeve 2.
The outer annular conical surface and/or the oriented angular surface is provided with a plurality of annular grooves with a gradually narrowing outer diameter and the two adjacent grooves form an annular protrusion.
As another embodiment of this disclosure, the method for using the quick tire repairing nail comprises following steps of:
(a) rotating a tire installed in an automobile that needs to be repaired to the repairing position where the puncture wounds of the tire is visible, examining whether the puncture wounds has a foreign matter within it and pulling out the foreign matter if it exists; and
(b) aiming the sharp portion of the front end of the tire repairing screw at the puncture wounds, using a tool and making the tool match with the concave-convex matching structure, rotating the tool by the action of an external force and thus driving and squeezing the tire repairing screw, the sealing sleeve and the screw head continuously into the puncture wounds wherein the rear end face of the screw head is flush with the outer surface of the vehicle tire or the rear end face of the screw head is caught in the outer surface of the vehicle tire.
Compared with the prior art, the advantage of the present invention is:
First, the quick tire repairing nail is screwed into the puncture wounds with its screw threads formed on the front end, and the soft sealing sleeve which is wrapped up in the outer surface of the tire nail is squeezed/intruded into deep wound with the air checking ring and screw head together, to plug, squeeze, and infiltrate the puncture wound. As such, the soft sealing sleeve can couple the damaged surfaces and adhere the screw, to fill the puncture wound and prevent air leakage.
Second, the quick tire repairing nail and method thereof can be used without completely disassembling the wheels and being connected to the car, as long as the users know how to use a repair tool to screw the tire nail into the tire, the puncture wounds can be repaired. The driver may complete the repairing job at any time on their own, not requiring any dedicated professional staff or device. That is to say, the method is particularly simple and in low cost, but fast and with good sealing performance, and can be completed at any time.
Third, the quick tire repairing nail is intruded into the tire from the outer surface thereof, thus, it can completely avoid other foreign matter rip into the original puncture wounds from the appearance of the original tire puncture wound again to cause the air leakage. Therefore, the reliability of repairing is enhanced, and more advantage than the traditional cold and hot tire repairing method.
Fourth, the structure is simple and easy to manufacture.

The optimum scheme is that the outer diameter of the air checking ring 14 is less than the outer diameter of the screw head 12. The air checking ring 14 may further improve the connection strength between the sealing sleeve 2 and the tire repairing screw 1. Meanwhile, after squeezing into the puncture wounds, the present embodiment may increase the connection structure strength with the vehicle tire, thereby avoiding the occurrence of falling out. In addition, even though the screw head 12 is worn, the air checking ring 14 may function as a second defensive line, thereby avoiding the loss of sealing function once the screw head 12 is worn.
Additionally, the sealing sleeve 2 sleeves the outside of the air checking ring 14. The sealing sleeve 2 is injection molded and firmly embeds the tire repairing screw 1, the screw head 12 and the air checking ring 14. The operation of the structure may increase the connection structure strength and the sealing between each other, thereby avoiding the leakage of the air within the vehicle tire after the completion of repairing the tire. Of course, the sealing sleeve 2 of the embodiment may be prepared separately and sleeves the outsides of the tire repairing screw 1, the screw head 12 and the air checking ring 14.
Furthermore, the outer wall of the screw head 12 is provided with an outer annular conical surface 15 slanting towards the tire repairing screw 1 and the end of the sealing sleeve 2 nearing the screw head 12 is provided with an inner annular conical surface 21 matched with the outer annular conical surface 15. The outer annular conical surface 15 and/or the oriented angular surface 14a is provided with a plurality of annular protrusions 15a with a gradually narrowing outer diameter and each two adjacent annular protrusions 15a are connected or spaced. As shown in
The quick tire repairing nail of the embodiment may be used to repair the punctured cover tires of the automobile, the motorcycle or the engineering vehicle by directly blocking the puncture hole and as a kind of “first aid” product for vehicles that may be taken along with vehicles.
As shown in
