Abstract
The utility model discloses a convenient inner tyre for a bicycle. The inner tyre comprises a tyre body and a main air tap, wherein an isolated rubber belt is connected to the tyre body in an airtight manner and is used for dividing a space in the tyre body into a main air cavity and a secondary air cavity; the main air cavity is formed on the inner side of the secondary air cavity; the section area of the main air cavity is larger than that of the secondary air cavity; the main air tap is communicated with the main air cavity in an airtight manner; the second air cavity is communicated with a secondary air tap in an airtight manner; and the secondary air tap corresponds to the main air tap. When the inner tyre is punctured by sharp particles such as glass, air in the main air cavity can be stored well under the protection of the isolated rubber belt, and only does air in the secondary air cavity leak out, so that the bicycle can still run even if the inner tyre is punctured, and the inner tyre brings convenience for people.
Description
Technical field
The utility model relates to a kind of inner tube of a tyre, relates in particular to a kind of convenient bicycle tube.
Background technology
A kind of convenient bicycle tube that uses at present is after being punctured by sharp-pointed particles such as glass, and the gas in the inner tube of a tyre can almost all be exposed to light accidentally, and bicycle can not continue to ride, and makes troubles to people.
The utility model content
The utility model provides a kind of a kind of convenient bicycle tube easy to use for deficiency.
The technical scheme that the utility model solves the problems of the technologies described above is as follows:
A kind of convenient bicycle tube, comprise carcass and main valve, it is characterized in that, the airtight isolation rubber tape that is connected with in the carcass, the isolation rubber tape is main air cavity and time air cavity with the spatial separation in the carcass, it is inboard that main air cavity is positioned at time air cavity, the sectional area of main air cavity is greater than the sectional area of inferior air cavity, main valve communicates with main air cavity is airtight, the airtight time valve that is communicated with of inferior air cavity, and inferior valve is corresponding with main valve.
The beneficial effects of the utility model are:
After the utility model is punctured by sharp-pointed particles such as glass; only have the gas in the inferior air cavity to run away, the gas in the main air cavity is saved intact under the protection of isolation rubber tape, although the inner tube of a tyre is pricked; but bicycle still can continue to travel, and this provides convenience to people undoubtedly.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A generalized section of Fig. 1.
In the accompanying drawing:
1, carcass; 2, main valve; 3, inferior valve; 4, isolation rubber tape; 5, inferior air cavity; 6, main air cavity.
The specific embodiment
