Abstract
The utility model discloses a poke-proof cushion for a pneumatic tire, relating to the tire, in particular to a reinforcing piece of the tire. The poke-proof cushion for the pneumatic tire used for preventing objects of iron nails with sharp point damaging the pneumatic tire comprises a metal-belt fixing piece and a soft protecting layer, and the poke-proof function can be provided through the poke-proof cushion is arranged between the inner and outer tires of various pneumatic tires. The poke-proof cushion not only can be used for the poke-proof pneumatic tire of a light-duty vehicle, but also can be used for the poke-proof pneumatic tire of a vehicle with heavier loading. Because the utility model adopts the metal belt with high hardness, the goal brought forward can be attained completely, and the material of the selected metal belt and the protecting layer can have low price, wide source and simple manufacture.
Description
The air-inflation tyre poke-proof cushion relates to tire, more specifically to tire reinforcement provided.Be used to prevent that band sticker bodies such as iron nail from poking air-inflation tyre.
Air-inflation tyre has been widely used for various transport vehicles.The situation of leaking gas but air-inflation tyre is poked by band sticker bodies such as iron nails is of common occurrence.For this reason, external existing a kind of bicycle poke-proof cushion made from polyurethane (polyurethane, polyurethane) plastics, between the inside and outside tire of bicycle, can prevent that short and small band sticker body such as cullet, borings from poking the inner tube of a tyre and causing gas leakage in order to lining.But,, can not prevent protruding into of spininess objects such as iron nail, drawing pin because the hardness of polyurethane plastics is lower.And the price of polyurethane plastics own is more expensive, and its output is less, is difficult to satisfy the needs that poke-proof cushion is produced.In addition, for the heavier automobile of load, the poke-proof cushion of tractor tire, the home and abroad does not also occur at present.
The purpose of this utility model is to provide a kind of higher sharp shaped materials such as iron nail of hardness that can prevent to poke the poke-proof cushion of the inner tube of a tyre.Be not only applicable to anti-stamp of air-inflation tyre of light-duty vehicles such as bicycle, hand barrow, motor bike, and be applicable to anti-stamp of air-inflation tyre of the heavier automobile of load, trac..
The utility model poke-proof cushion comprises metal tape, connecting element and soft protective cover.As a kind of form of the present utility model, poke-proof cushion is a soft protective cover of outsourcing, the metal tape of head and the tail overlap joint.Be applicable to the anti-stamps of light-duty vehicle tire such as bicycle.The poke-proof cushion of another kind of form be one by many strip metals band of head and the tail overlap joint and the connecting element on every strip metal band and the band formed by the protective cover of fixing interior band of connecting element and both sides thereof.Be applicable to the anti-stamps of light-duty vehicle tire such as bicycle.The poke-proof cushion of another form be one by many vertically head and the tail overlap joint, the laterally metal tape of scale types overlap joint and the connecting element on every strip metal band and the bands formed by the protective cover of fixing interior band of connecting element and both sides thereof.Be applicable to heavier anti-stamps of air-inflation tyre of load such as automobile.
The utility model poke-proof cushion has been owing to adopted the higher metal tape of hardness, can prevent that not only cullet, metal from cutting short and small band sticker body such as genus and poking the inner tube of a tyre, and can prevent that various spininess objects such as iron nail, drawing pin from poking the inner tube of a tyre.And, selected metal tape and protective layer material cheap, the source is wide, makes simple.Also can be suitable for the anti-stamp that all have airtyred vehicle.
Below, will do more specifically narration to the utility model in conjunction with the accompanying drawings and embodiments.
Description of drawings:
Fig. 1 is the partial cross section scheme drawing of light-duty tire for vehicles such as bicycle;
Fig. 2 is that a many strip metals band by the head and the tail overlap joint is formed the anti-scheme drawing that stabs band;
Fig. 3 for the C of Fig. 2 to the part exhibition look cutaway view;

Embodiment 1
With reference to Fig. 1, poke-proof cushion 4 linings of the present utility model are between the cover tire 2 and the inner tube of a tyre 3.Poke-proof cushion 4 is made up of a metal tape 6 and the protective cover 5 of cladding on metal tape.Metal tape 6 preferably adopts the band steel of Cold Rolled Strip, also can adopt the band steel of hot-rolled state band steel or process cure process.It is long that its length is slightly larger than the inner periphery of cover tire of the tire that serves as a contrast, and its width is slightly larger than or equals tire and is subjected under the load and ground-surface contact width, and its thickness is decided on material, concerning general band steel, is advisable with 0.3~0.8 millimeter.Make this metal tape form a firm resilient again endless belt, the joint, two ends is the overlap joint shape.Endless belt outsourcing last layer soft material is made protective cover.This soft material protective cover can be a kind of fabric, also has the plastics or the rubber of sufficient intensity.
With reference to Fig. 2~4; as the another kind of form of light-duty vehicles such as bicycle 1 tire poke-proof cushion, poke-proof cushion 9 is fixed plates 8 fixing on a many strip metals band 6 by head and the tail overlap joints, the every strip metal band 6 and makes in metal tape 6 and the annular soft protection with 7 by fixed plate 8 and to be with 7 to form in fixing.In suitable with girth in the cover tire of 7 length and institute's pad vehicle.According to the number of the fixed plate of being fixed on the bar number of employing metal tape 6 and the every strip metal band 8, offer two on 7 on the corresponding distance perpendicular to interior 7 joint-cuttings longitudinally of being with interior being with.Its width matches with U-shaped fixed plate 8 with distance.Every as the metal tape 6 of width as described in the embodiment 1 and thickness laterally with the radius of curvature bendings of tire.The U-shaped fixed plate 8 of on the middle part of every strip metal band or other position, burn-oning securely.The bipod that is welded in U-shaped fixed plate on the metal tape is inserted in the corresponding with it annular with in 7 the joint-cutting, and with the bipod of U-shaped fixed plate 8 outwards or curve inwardly and flatten, every strip metal band 6 is fixed in the annular is with.Tail overlaps mutually first of every strip metal band, forms an anti-band that stabs of osed top annular.Since in have certain toughness, can keep anti-flexibility of stabbing band.From the part, every strip metal band has enough rigidity again, and the head and the tail overlap joint can prevent that again various stickers from protruding into from the joint of positive or two strip metal bands.
Consider that anti-band and the U-shaped fixed plate of stabbing of metal do not remove at the burr that adds man-hour and totally and easily make inside and outside tire impaired.Therefore, anti-both sides of stabbing band serve as a contrast the protective cover 5 that last layer is made up of high-abrasive materials such as various fabrics, plastics or rubber again.
With reference to Fig. 5, as a kind of form of the poke-proof cushion of the heavier vehicle of automobile even load, poke-proof cushion 10 adopts the mode with the head and the tail overlap joint described in the embodiment 2 in the vertical, on Width, adopts many head and the tail overlap joints modes that overlap of fish scales mutually again.The thickness of metal tape is concerning steel band; be advisable with 0.5~1.2 millimeter; every strip metal band 6 all is with in being fixed on by being welded in fixed plate on every strip metal band securely; its fixed form is described with embodiment 2; its both sides serve as a contrast the protective cover 5 that last layer is made up of each and high-abrasive materials such as fabric, plastics or rubber again, perhaps the protective cover 5 of the high-abrasive material composition of fabric and rubber composition.The number of the fixed plate on every strip metal band and the width of every strip metal band and length are according to the suffered payload of tire and different.
