Abstract
The utility model relates to a safety inner tube, which is composed of a tube body and a plurality of air intake valves (4), wherein, a plurality of small space which are not communicated with each other are formed in the tube body according to a certain mode; the certain small space which leaks the air does not cause other small space to leak the air.
Description
The utility model relates to a kind of inner tube of a tyre of vehicle tyre.It can be widely used in various self-propelled vehiclees (as automobile) and unpowered vehicle (as bicycle).Existing all kinds of inner tube is made with rubber mostly, and inside is full of air, as the tire bearing force.There is following shortcoming in it: in case inner tube of a tyre point is damaged, all cause whole inner tube of a tyre gas leakage, make vehicle tyre lose bearing force fully, can't use, and must change immediately.Cause potential safety hazard and greatly inconvenience to the user.Thereby to reform existing tire inner tube be necessary.
The utility model is exactly design-calculated in order to overcome above deficiency." punctured-proof tube " has simple in structure, and be easy to use, is difficult for gas leakage, the feature that safety is higher.
To achieve these goals, scheme of the present utility model is: " punctured-proof tube " is made up of with a plurality of air intake valves (structure is identical with existing valve) carcass.The inside of its carcass is split into not connected a plurality of parts.Entering of each portion gas by an air intake valve control.In case inner tube of a tyre point damaged (or being punctured) only makes the inner tube of a tyre partly leak gas like this, and loses the part bearing force.Even so vehicle tyre still can use, and needn't change immediately or repair.On time and space, arrange change or repair appropriate opportunity for the user, provide and may and make things convenient for.
Be equivalent in a tire, install a plurality of less inner tubes of a tyre according to this programme design-calculated " punctured-proof tube ".The damage of wherein some (or part), gas leakage can not influence the bearing force of tire fully.Vehicle still can use in certain hour and scope like this.
The inside dividing method of " punctured-proof tube " is more, below in conjunction with two examples scheme is elaborated:
Fig. 1 is the inner a kind of example schematic diagram cut apart by annular of carcass.
A kind of example schematic diagram that Fig. 2 is cut apart by segmentation for carcass inside.
Among the figure: 1 is " punctured-proof tube " outer rim, and 2 is inner edge, and 3 is the inner dividing layer of carcass, and A, B, C represent to cut apart the little space of formation respectively.4 is air intake valve (identical with existing air intake valve structure), 5 total air intake valves.
Among Fig. 1, when the inner tube of a tyre was inflated, gas at first passed through air intake valve (5) and enters in the tire, passed through the interior air intake valve (4) of tire simultaneously and entered whole inner tube of a tyre space, and reach the requirement of normal operation.If carcass point gas leakage in the A space in the use will cause in the A space all gas to miss, but B, C space aerification still.Thereby whole tire only is subjected to limited influence, and can not completely lose bearing force.Therefore tire still can use in a time, scope, and needn't change immediately when inconvenience.
Comprehensively described, the utility model is an actv..
Claims (3)
1, a kind of punctured-proof tube is characterized in that: be made up of carcass and several air intake valves (4,5).
2, it is characterized in that according to the described punctured-proof tube of claim 1: can cut apart the method for cutting apart with segmentation by annular and form several not connected spaces (as: A, B, C) respectively, its each space (as: A, B, C) all has an air intake valve (4).
3, according to the described punctured-proof tube of claim 1, it is characterized in that: air intake valve when annular is cut apart (4) is installed on respectively on the adjacent dividing layer in each space in the tire, and total valve (5) is installed in the carcass inboard with the total space of air intake valve (4); When segmentation was cut apart, air intake valve (4) was installed in every section carcass (as A, B, C) inboard respectively.
