Abstract
The utility model relates to an anti-pricking cover for inflatable inner tubes. A cover body is an annular body with bending elasticity, wherein, the cross section of which is provided with an opening towards a wheel rim for coating an inner tube and a cover surface of which is appressed with the inner surface of a tyre cover after the inner tube is inflated. The anti-pricking cover for inflatable inner tubes has the advantages of novel concept, reasonable design, convenient fabrication, and convenient installation and operation and can effectively prevent accidents that various inflatable tyres are punctured to leak air by sharp objects, extends the service life of an inflatable inner tube, saves the maintenance cost and maintenance time for tyres, and improves the reliability of the running of wheels. The cover body which has certain bending elasticity can have a damping action and fit for the deformation of the tyre cover to play a puncture preventing efficiency when the inflation level of the inner tube is changed.
Description
The utility model relates to airtyred enhancement layer, relates in particular to a kind of inflatable inner tube anti-pricking cover.
The air-inflation tyre of existing wheel adapted includes the cover tire and the inner tube of a tyre, and cover tire is formed by rubber and the mold pressing of nylon warp and filling mostly, its resistance to abrasion is good, but easily penetrated, and the inner tube of a tyre that punctures the caoutchous goods causes gas leakage, make the wheel can not cruising by the sharp object on the road surface.China utility model patent CN2172733Y, CN2173717Y and CN2176268Y be " tire Puncture-preventing ring ", " the anti-bundling device of inner tube " and " the not broken device of tire " of public Defendant respectively, can address the above problem, but, manufacturing process is more numerous and diverse, and in-use performance needs further improvement.
The purpose of this utility model is to remedy the deficiencies in the prior art to propose a kind of inflatable inner tube anti-pricking cover.
The purpose of this utility model is achieved by the following technical programs.
This inflatable inner tube anti-pricking cover is arranged between the airtyred inside and outside tire, it is characterized in that cover body be a cross-sectional plane towards wheel rim have opening to coat the inner tube of a tyre cover after inner tube of a tyre inflation, be close to the round body with elasticity of flexure of inner surface of cover tyre.Cover body thickness is 2～4 millimeters, and manufactured materials is fiber reinforced composite, as aramid fiber-1414 super-strength syntheticfibres, carbon fiber, metal fibre paper, high-modulus oriented thermoplastic material (HMOPP) or the like.These materials all have plasticity height, characteristics that toughness is strong.
The utility model is novel, and is reasonable in design, makes simple, easy to install, can prevent effectively that various types of air-inflation tyres from being taken place by the accident that sharp object punctures gas leakage, prolongs the service life of inflatable inner tube, save Luntai service expenditure and time, improve the reliability that wheel travels.The utility model also has an amount of elasticity of flexure, both can play cushioning effect, can also be when inner tube of a tyre gas charging degree change, and adapt to the distortion of cover tire and bring into play anti-stab usefulness.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with embodiment and contrast accompanying drawing the utility model is made an explanation.
Embodiment motor bike inflatable inner tube anti-pricking cover
This anti-pricking cover cover body thickness is 2 millimeters, with the compression molding of aramid fiber-1414 super-strength syntheticfibres.When installing and using, earlier cover 1 is close to inner surface of cover tyre, again the unaerated inner tube of a tyre is disposed the inner chamber 3 from opening 2, then cover tire, anti-pricking cover and the unaerated inner tube of a tyre are enclosed within on the wheel rim, charge into pressure gas to the inner tube of a tyre at last, the inner tube of a tyre is promptly by anti-bundle cover and wheel rim banding.
During travelling, wheel meets that sharp object stings cover tire and when touching cover 1; sharp object can only force cover body generation part to be the concavity distortion and eyelet can not occur; can not injure the inner tube of a tyre and cause gas leakage; the rubber layer of cover tire both sides, protection carcass plies are punctured by outer powerful extruding; equally can not injure the inner tube of a tyre yet and cause gas leakage; even the cover tire both sides suffer major injury, anti-pricking cover still can be protected the unlikely accident of blowing out of the inner tube of a tyre.
Claims (3)
1, a kind of inflatable inner tube anti-pricking cover is arranged between the airtyred inside and outside tire, it is characterized in that cover body be a cross-sectional plane towards wheel rim have opening to coat the inner tube of a tyre cover after inner tube of a tyre inflation, be close to the round body with elasticity of flexure of inner surface of cover tyre.
2, inflatable inner tube anti-pricking cover as claimed in claim 1 is characterized in that cover body thickness is 2～4 millimeters.
