Problems solved by technology

But in the process of patching and screwing in, the sealing sleeve festered
The actual sealing function is the thread and the air stop ring. After the repair, during the movement of the car tire, air leakage will occur. Because the nail is rigid, the tire is repeatedly deformed during the operation of the tire, and the relative movement of the fitting surface occurs. friction, resulting in seal failure

Embodiment 1

[0037] Embodiment one: see figure 1 As shown, a new type of tool for repairing a tire without picking up a tire includes a screw 1, see Figure 4 As shown, the surface of the screw 5 of the screw 1 is provided with a viscous film layer 2, the film layer 2 extends from the head of the screw to the screw area of ​​the screw 2, the inner surface of the film layer 2 is in contact with the The surface of the screw rod 5 of the screw 1 is bonded.

[0038] In this embodiment, the screw head 4 is in the shape of a truncated cone, and the diameter of the outer surface is larger than the diameter of the inner surface.

[0039] In this embodiment, the thickness of the screw head 4 is 1.1 mm, 1.3 mm or 1.5 mm, and the screw head 4 is thinned to further increase the length of the thread and improve the repair space.

[0040] In this embodiment, the maximum diameter of the outer surface of the head of the screw 1 (that is, the maximum diameter of the outer surface of the frustum-shaped st...

Embodiment 2

[0061] Embodiment two: see figure 2 As shown, a new type of tire-repairing tool without pick-up includes a screw 1, the surface of the screw 5 of the screw 1 is provided with a sticky film layer 2, and the film layer 2 extends from the head of the screw to the screw 2. The screw area of ​​the screw extends, and the inner surface of the adhesive film layer 2 is bonded to the surface of the screw 5 of the screw 1.

[0062] In this example, see figure 2 As shown, the adhesive film layer 2 is wrapped and bonded on the screw rod, and generally has a conical structure.

[0063] In this embodiment, the thickness of the screw head is 1.2 mm, that is, the thickness of the frustum-shaped structure is 1.2 mm. The screw head is thinned, the length of the thread is further increased, and the repair space is improved. In this embodiment, the diameter of the outer surface of the head of the screw 1 is 5.5 mm, and the diameter of the head of the screw 1 is reduced to facilitate screwing t...

Abstract

The invention discloses a novel tire-stripping-free tire repairing tool and a using method thereof. The novel tire-stripping-free tire repairing tool comprises a screw, the surface of a screw rod of the screw is provided with an adhesive film layer with viscosity, and the inner surface of the adhesive film layer is bonded with the surface of the screw rod of the screw. According to the novel tire-stripping-free tire repairing tool, a guide head at the tail is used for piercing a wound, a screwdriver is used for screwing in, in the screwing-in process, a steel wire mesh penetrating through a carcass forms an extremely strong occlusion relation, meanwhile, threads are wedged into the carcass, the adhesive film layer rolls and migrates in a hole, an internal vacancy is randomly filled, threadvalleys are blocked, and gas loses a leakage channel, so that the effects of filling wounds and preventing air leakage are achieved.

Description

technical field [0001] The invention relates to a novel tire-repairing tool without picking and a method for using the same, belonging to the technical field of tire repairing. Background technique [0002] In the prior art, a tire patching method requires dismantling the wheel, removing the tire from the hub, grinding the area near the leak point inside the tire, and pasting a piece of unvulcanized rubber And on the vulcanizing machine, the film and the tire are heated to the vulcanization temperature for partial vulcanization. After the vulcanization is completed, the film and the tire have strong adhesion. In actual operation, due to the poor temperature control accuracy of this simple vulcanizer, the temperature may be too high and the tire body may be damaged. At the same time, due to This method is time-consuming and less and less used. [0003] Now the most commonly used method of tire repair is the cold repair film method, which also requires dismantling the tire a...
