Description

The bicycle that directly has aerator

The utility model relates to the gas filled device of bicycle and bicycle.

At present, bicycle still is a kind of easy vehicle that generally use in China, but can slowly become flat behind the inflation of tire of bicycle, cause to beat once gas in several days, when particularly going out by bike, sometimes look about the place of inflating, caused inconvenience owing to gas leakage causes the cyclist to walk one's bicycle to people.

The purpose of this utility model provides and does not a kind ofly need in addition to join aerator again but bicycle that aerator that utilization itself directly has just can be inflated.

Technical solution of the present utility model is such, A-frame at existing bicycle, the car handrail, front fork, before, trailing wheel, on the basis of pedal driver, positon of near bottom has a freeing pipe that is connected with standpipe outside the standpipe of the utility model in A-frame, the lower end has and can allow the air folk prescription to current boiler check valve in standpipe, be inserted with a pull bar in the standpipe, be fixed with the Inflation plug of a compressible air in the lower end of pull bar, the short tube that the upper end of pull bar and diameter are littler than standpipe internal diameter slightly fixes, and short tube and seat cushion fix, side-walls has a hole in the nearly upper end of standpipe, rotatablely in the hole be fixed with a check screw, also be fixed with the fixed ring piece of a movable taking-up in the pipe below the hole, fixed ring piece and standpipe are perpendicular.

Principle of work of the present utility model is to get a sebific duct one end earlier to be enclosed within on the mouth of freeing pipe, and the other end is enclosed within on the Air inflating valve of wheel.Thereafter can unclamp the check screw of A-frame standpipe upper end, just seat cushion upwards can be dialled, owing to seat cushion and pull bar fix, therefore the Inflation plug fixed of pull bar lower end also moves up, promptly has air to charge in the pipe below the Inflation plug.Thereafter with seat cushion to pressing down, force Inflation plug to enter sebific duct from boiler check valve and freeing pipe to compressed air, enter in the tire through the wheel valve again.After having beaten gas, seat cushion is pressed onto the end as far as possible, the short tube that fixes with seat cushion is hidden in the standpipe, tighten check screw and remove fixedly short tube this moment, and seat cushion just is fixed tightly on the standpipe, and seat cushion can left and rightly not wave in the time of by bike.Fixed ring piece below the hole of standpipe internal fixation screw owing to can limit the left and right swing of pull bar, and prevents because of seat cushion upwards being drawn to such an extent that too high the whole piece pull bar is transferred to outside the standpipe, and the Inflation plug impassabitity fixed ring piece of restriction pull bar lower end.Can twist under the seat cushion or other place after sebific duct of inflating usefulness of the present utility model uses up, convenient as far as possible use at any time.

The utility model has the advantages that bicycle itself directly has aerator, and do not need to join in addition again aerator, and can inflate at any time, made things convenient for people's use.

Below in conjunction with accompanying drawing embodiment of the present utility model is described

Fig. 2 principle of work scheme drawing of the present utility model

Fig. 3 position view of the present utility model

According to Fig. 1, shown in 2, the bicycle that the utility model adopts is with existing commercially available identical, A-frame is arranged, the car handrail, front fork, before, trailing wheel, pedal driver constitutes, the utility model mainly is that positon of near bottom has a freeing pipe that is connected with standpipe 2 outside the standpipe 1 in A-frame, the lower end has one can allow the air folk prescription to current boiler check valve 9 in standpipe 1, in standpipe 1, be inserted with a pull bar 3, be fixed with the Inflation plug 4 of a compressible air in the lower end of pull bar 3, the short tube 7 that the upper end of pull bar 3 and diameter are littler than standpipe 1 internal diameter slightly fixes, short tube 7 fixes with seat cushion 6, side-walls has a hole in the nearly upper end of standpipe 1, rotatablely in the hole be fixed with a check screw 5, also be fixed with the fixed ring piece 8 of a movable taking-up in the pipe below the hole, fixed ring piece 8 is perpendicular with standpipe 1.The diameter of the centre hole of fixed ring piece 8 is bigger slightly than the diameter of pull bar 3.

Claims

1, the bicycle that directly has aerator, comprise bicycle tripod, the car handrail, front fork, before, trailing wheel, pedal driver constitutes, it is characterized in that the outer positon of near bottom of standpipe (1) in the A-frame has a deflation hole that is connected with pipe (2), there is boiler check valve (9) lower end in standpipe (1), be inserted with a pull bar (3) in the standpipe (1), be fixed with the Inflation plug (4) of a compressible air in the lower end of pull bar (3), the short tube (7) that the upper end of pull bar (3) and diameter are littler than standpipe (1) internal diameter slightly fixes, short tube (7) fixes with seat cushion (6), on the sidewall of the nearly upper end of standpipe (1), a hole is arranged, the rotatable check screw (5) that is fixed with in the hole also is fixed with the fixed ring piece (8) of a movable taking-up in the pipe below the hole, fixed ring piece (8) is perpendicular with standpipe (1).

2, the bicycle that directly has aerator according to claim 1 is characterized in that the diameter of centre hole of fixed ring piece (8) is bigger slightly than the diameter of pull bar (3).
