Abstract
The utility model discloses an automatic air inflation valve of a bicycle tire, which comprises an air valve core, wherein an air inlet pipe of the air valve core is provided with an air inlet hole. The air inlet hole is connected with an air guiding pipe. The air guiding pipe is connected with a communicated piston cylinder, and the other end of the air guiding pipe is provided with an air outlet hole. The air inlet hole on the air inlet pipe and the air outlet hole on the air guiding pipe are respectively provided with a one-way valve, and the device is arranged in a bicycle tire. When the air pressure of the bicycle tire is sufficient, the bicycle tire can not be flatly pressed and a piston rod of the piston cylinder keeps stationary. The bicycle tire can not be inflated by the piston. After a part of air in the bicycle tire is dispersed, the bicycle tire is flatly pressed. After the piston is in contact with ground, the piston rod can be pushed for inflating the bicycle tire. The utility model has the advantages of simple structure and convenient use.
Description
Technical field
The utility model belongs to bicycle assembly parts, is specifically related to the automatic charge valve of bike tyre.
Background technology
Bicycle is extensive use of at home, and the user can usually run into because the India rubber tube of valve inside is aging, the situation that tire loses heart slowly.Cycling tire unsaturated vapor like this, the difficulty of riding.
Summary of the invention
The purpose of this utility model be to provide a kind of can automatic gas filed bike tyre when bike tire's unsaturated vapor automatic charge valve, to address the above problem.
The technical solution of the utility model is: the automatic charge valve of bike tyre, it comprises valve inside, also offer induction opening on the air inlet pipe of valve inside, connect the ventilation flue on the induction opening, the last connection of ventilation flue UNICOM piston cylinder, ventilation flue's the other end sets out pore, is equipped with check valve on induction opening on the air inlet pipe and the air gate on the ventilation flue.
This device is located in the cycle tyre, and when the air pressure of ride was enough, tire was not flattened, and the piston rod of piston is motionless, and promptly piston is not given Tyre inflating; After the gas in the tire had disappeared a part, tire was flattened, and after piston landed, piston rod will be pushed to Tyre inflating.It is simple in structure, and is easy to use.
Description of drawings
The automatic charge valve scheme drawing of accompanying drawing bike tyre
The specific embodiment
Also offer induction opening 3 on the air inlet pipe 2 of valve inside 1, connect ventilation flue 4 on the induction opening 3, connect UNICOM's piston cylinder 5 on the ventilation flue 4, ventilation flue 4 the other end sets out pore 6, is equipped with check valve 7 on induction opening 3 on the air inlet pipe 2 and the air gate 6 on the ventilation flue 4.Also be located at the rubber case 9 of identical induction opening of existing structure 8 and covering induction opening 8 on the valve inside 1.Establish retracing spring 11 in the rodless cavity 10 of piston cylinder 5.
Claims (2)
1, the automatic charge valve of a kind of bike tyre, it comprises valve inside, it is characterized in that also offering induction opening on the air inlet pipe of valve inside, connect the ventilation flue on the induction opening, the last connection of ventilation flue UNICOM piston cylinder, ventilation flue's the other end sets out pore, is equipped with check valve on induction opening on the air inlet pipe and the air gate on the ventilation flue.
2, the automatic charge valve of bike tyre according to claim 1 is characterized in that establishing retracing spring in the rodless cavity of piston cylinder.
