Abstract

The utility model discloses a cloth inserted rubber sheet used for repairing the automobile tires, which comprises a pasting rubber plate at the outer layer, a backing plate at the inner layer and a plurality of cloth inserted layers clamped between the pasting rubber plate and the backing plate. The cloth inserted rubber sheet is made of the waste and used cloth inserted automobile tires, the outer layer is ground to be a cambered surface which is inosculated with the size of the inner wall of the tire, and the inner side, the outer side and the cloth inserted layer are thick in the center and thin on the periphery, namely, the cloth inserted rubber sheet becomes thin gradually from inside to outside from the periphery of the backing plate, and is connected with the tire firmly. Because the thickness at the backing plate is larger, moreover the cloth inserted rubber sheet is provided with the cloth inserted layer identical with the tire, the intensity is high, the phenomenon that the tire generates secondary rupture at the cracking and pasting part can be avoided, and the service life is enhanced. Because the cloth inserted rubber sheet is made of the waste and used cloth inserted rubber sheet, the material cost can be saved, the cost is reduced, the waste can be changed into valuables, and the economic benefit and the social benefit are enhanced.

Description

Doughnut is repaired and is used sheblack rubber insertion sheet

Technical field

The utility model relates to a kind of doughnut, the repairing sheblack rubber insertion sheet that uses when being specifically related to the gas leakage of doughnut breach.

Background technology

During tyre leakage, if the tire of the inner tube of a tyre is arranged, the old inner tube of a tyre of general using or cold patch are bonding with binding agent, and tubeless tyre is vulcanized with the external tire of tire patching film inboard.The sort of repairing way no matter, because the sticking film thin thickness of mending, intensity is low, occurs the secondary gas leakage of breaking behind tire patching.Thicker rubber cushion is also arranged at present on the market, but do not have canvas filler layer in the middle of it, or the canvas filler layer thin thickness, intensity difference, the tire after the repairing still can be from former rent crackings, and service life is low.

Summary of the invention

The purpose of this utility model provides a kind of doughnut repairing sheblack rubber insertion sheet, and it comprises the backing plate of outer field stickup offset plate, internal layer and is installed in the multilayer canvas filler layer of pasting between offset plate and the backing plate.It is to utilize waste and old folder cloth doughnut to make, its outer mill is repaiied to the crooked cambered surface that matches with the tire inner wall size, and its inboard is that the center is thick, periphery is thin together with the thickness of canvas filler layer, promptly from the beginning of backing plate periphery, attenuation gradually from inside to outside, the thickness of outer edge is not more than 1～2mm.

The utility model is achieved by the following technical solution: a kind of doughnut is repaired and used sheblack rubber insertion sheet, it is characterized in that: it comprises the backing plate of outer field stickup offset plate, internal layer and is installed in multilayer canvas filler layer between described stickup offset plate and the backing plate.

The rectangle offset plate that described stickup offset plate is four jiaos of excessive fillets of band, its lateral surface is made into the crooked cambered surface that matches with the doughnut inwall, thickness together with canvas filler layer is that the center is thick, periphery is thin, promptly from the beginning of described backing plate periphery, attenuation gradually from inside to outside is not more than 1～2mm until the thickness of outer edge.

Good effect of the present utility model is:

1, bonding firmly is not easy cracking.

2, canvas filler layer intensity height can be in mend secondary cracking, long service life.

3, utilize junked tire to make, fee of material is cheap, is convenient to promote the use of.Improve the economic and social benefits.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the left view of Fig. 1;

Among the figure: 1, paste offset plate, 2, canvas filler layer, 3, backing plate.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3: a kind of doughnut is repaired and used sheblack rubber insertion sheet, it is characterized in that: it comprises the backing plate 3 of outer field stickup offset plate 1, internal layer and is installed in multilayer canvas filler layer 2 between described stickup offset plate 1 and the backing plate 3.

Described stickup offset plate 1 is the rectangle offset plate of four jiaos of excessive fillets of band, its lateral surface is made into the crooked cambered surface that matches with the doughnut inwall, thickness together with canvas filler layer 2 is that the center is thick, periphery is thin, promptly from described backing plate 3 periphery beginnings, attenuation gradually from inside to outside is not more than 1～2mm until the thickness of outer edge.

As Fig. 1, Fig. 2, shown in Figure 3:

During making, the length of the size of breaking according to waiting to mend a tire, cut the rectangular slab of corresponding size with waste and old folder cloth tire, the lateral surface mill is accomplished the stickup offset plate 1 of the crooked cambered surface that matches with doughnut inwall size, paste offset plate 1 inboard and accomplish together with the thickness mill of canvas filler layer 2 that the center is thick, periphery is thin, promptly begin from backing plate 3 peripheries, attenuation gradually from inside to outside, the thickness of outer edge is not more than 1～2mm.To paste the polishing of offset plate 1 lateral surface again,, this folder cloth backing plate and tire be pasted and compacting with glue with polishing around the tire breach place.Because the thickness of folder cloth backing plate is that the center is thick, periphery is gradually thin, amplexiforms firmly with tire.Because backing plate 3 is in the position of tire breach, this place's thickness is bigger, and has the canvas filler layer identical with tire 2, and the intensity height avoids tire to break at cracking location for paste secondary, improves service life.Because adopt waste and old folder cloth tire to make, economical with materials is taken, and reduces cost, and turns waste into wealth, and improves the economic and social benefits.
