Technical Field

The invention relates to an auxiliary tool for tire repair operation, in particular to an auxiliary repair device for a mute cotton tire.

Background

The mute cotton tire adopts a specially designed polyurethane sponge on the inner side of the tire, and can perform noise reduction treatment on noise resonance caused by a road surface. In the repair operation of the tire, the mute cotton becomes the biggest obstacle of tread repair, and the current repair mode is to cut and remove the mute cotton in the determined construction range after determining the repair construction range at the damaged position in the tire, so as to provide space for the subsequent tire body repair. However, the overall structure of the mute cotton in the tire is damaged by the repairing mode, so that the mute performance of the tire is greatly reduced, and the significance of using the mute cotton tire is lost.

Disclosure of Invention

The auxiliary repairing device for the mute cotton tire overcomes the defects of the existing repairing mode, not only well protects the integral structure and the mute performance of the mute cotton, but also can provide flexible and sufficient construction space for the subsequent tire body repairing.

In order to solve the technical problem, the invention provides an auxiliary repairing device for a mute cotton tire;

comprises a splint, a connecting band and a positioning clip;

the clamping plate comprises an upper limiting arm, an inner limiting arm and an outer limiting arm, the upper end of the inner limiting arm is connected with the upper end of the outer limiting arm through the upper limiting arm, and a limiting groove for clamping a toe opening at one side and a tire side of the silent cotton tire is formed between the inner limiting arm and the outer limiting arm;

the connecting band is fixed with the inner limiting arm of the clamping plate, and the end part of the connecting band is fixed with the positioning clamp.

In order to more clearly understand the technical content of the present invention, the auxiliary repair device for a silent cotton tire will be simply referred to as the present auxiliary repair device hereinafter.

As the optimization of the auxiliary repairing device, the clamping plate further comprises an adjusting nut and an adjusting bolt, the adjusting nut is fixedly connected to the outer side wall of the outer limiting arm, the adjusting bolt is matched with the adjusting nut, and the adjusting bolt penetrates through the outer limiting arm and extends into the limiting groove.

Preferably, the lower end of the outer limiting arm extends towards the inner limiting arm to form a tire shoulder limiting arm, and after the toe opening and the tire side of the mute cotton tire extend into the limiting groove, the tire shoulder limiting arm abuts against the tire shoulder of the mute cotton tire on the side.

As the optimization of the auxiliary repairing device, the included angle between the inner limiting arm and the upper limiting arm is an inner limiting angle, and the inner limiting angle is smaller than 85 degrees.

As the optimization of the auxiliary repairing device, the auxiliary repairing device also comprises an adjustable pressing buckle, the adjustable pressing buckle is fixedly connected to the inner side wall of the inner limiting arm, the adjustable pressing buckle is matched with the connecting belt, and the adjustable pressing buckle can limit the extending length of the connecting belt.

After adopting such structure, cotton overall structure of this supplementary patching device ability intact protection silence and silence performance to for follow-up matrix restoration provide nimble sufficient construction space, because this supplementary patching device has great adjustment range, can be used to the damage of the cotton tire of various specifications silence and restore, and support cold patch, hot patch and various repair tools, the cooperation of material is used, good compatibility and longer life have, through its reasonable design, small, and convenient to use is safe, the major structure of retrenching is convenient for manufacture, practicality and popularization nature have been improved.

The adjusting nut 14 is welded on the outer side wall of the outer limiting arm 13, the adjusting bolt 15 is matched with the adjusting nut 14, and the adjusting bolt 15 penetrates through the outer limiting arm 13 and extends into the limiting groove 17.

Adjustable pressure is detained 2 welding on the inside wall of spacing arm 12 including, and adjustable pressure is detained 2 and is connected the area 3 cooperation, and adjustable pressure is detained 2 and can be restricted the length that connecting band 3 stretches out, and connecting band 3 tip is fixed with positioning clamp 4.

During the repair construction of the mute cotton tire, marking the outer side damage position of the tire, detaching the tire to mark the inner side damage position of the tire, selecting a repair mode and a repair material according to the damage condition, determining the repair construction range in the tire, using a tire expander to expand the tire, selecting the side closest to the edge of the mute cotton according to the inner side damage position of the tire, using an art designer to sequentially cut the mute cotton from the mark position of the edge of the mute cotton to the determined repair construction range in a U shape, sticking the strip-shaped sealant of the mute cotton, and cutting the mute cotton until enough repair construction space exists;

according to the inner side damage position of the tire, a limiting groove 17 of a clamping plate is sleeved on a tire toe opening at one side far away from the silent cotton, an inner limiting angle alpha of the clamping plate is attached to the inner side of the tire toe opening, an adjusting bolt 15 is screwed to lock the outer side of the tire toe opening, meanwhile, under the action of locking forces in the tire toe opening and the outer side, the tire shoulder position is also attached to a tire shoulder limiting arm 16, at the moment, a connecting belt 3 is tensioned, the connecting belt 3 generates transverse tension, under the action of the transverse tension, a positioning clamp 4 forms downward pressure on the silent cotton, the degummed silent cotton is fully compressed under the action of the transverse tension and the downward pressure, a locking adjusting press buckle is formed, the fully compressed silent cotton is positioned, a flexible and sufficient construction space is provided for subsequent repair, after the tire body is repaired, sealant is recoated along the original strip-shaped sealant in the tire, the degummed position, and lightly pressing the mute cotton by hand to perfectly fix and restore the mute cotton, and at the moment, repairing the mute cotton tire is finished.

The above description is only one embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the principle of the present invention, and these should also be considered as falling within the protection scope of the present invention.
