Abstract

The utility model relates to a pedal inflating device for a motorcycle. In the utility model, a two-way valve is connected to pedal inflating device through the cylinder of the motorcycle, and the pedal inflating device is connected with an air cartridge and an air valve through a pressure rubber pipe. The inner part of the air cartridge is provided with filter materials. At the time of inflating, the air valve is connected with the valve core of the tyre, and the actuating lever of the motorcycle is trod repeatedly by foot to inflate rapidly and conveniently. The utility model has the advantages of small size, light weight, firm and durable structure and convenient portability.

Description

Pedal inflating device for motorcycle

The utility model belongs to a kind of motorcycle tire inflator.

Existing motorcycle tire inflation is many with pump or air compressor inflation, though air compressor is inflated convenient but can not arbitrarily be moved, more can not carry with car, need when inflating to motorcycle comparatively require great effort with handling with bicycle pump, and inconvenience carries, and can not make things convenient for use anywhere or anytime.Chinese patent by retrieval, a kind of " the miniature automatic high pressure gas-filled pump of Motor Vehicle tire " application number 92214228.9 is arranged, though this gas-filled pump can carry with car but need the Starter car engine to inflate when using, and one-way valve structures makes easily also that greasy dirt enters tire with gas in the cylinder, and it is impaired to cause tire.

The utility model purpose is to design a kind of pin of motorcycle easily and steps on aerator, and not only easy to carry but also greasy dirt tire not need not to start motorcycle engine, can give Tyre inflating quickly and easily.

The utility model is realized as follows: utilize the Cylinder of motorcycle that sheds spark plug, the aerator that access is made up of air valve, sebific duct, gas cartridge, valve cock, described air valve is a two-way valve, and its suction valve can be made up of air inlet nozzle in the screw-in valve body and air inlet steel ball and the spring in the valve pocket; The outlet valve of two-way valve can be made up of exhaust nozzle that screws in valve body and exhaust steel ball and the spring in the valve pocket, and in gas cartridge filtering material is housed.

Be elaborated below in conjunction with embodiment's accompanying drawing:

Fig. 1 the utility model schematic representation.

A figure is the utility model two-way valve front view among Fig. 2;

B figure is an a figure plan view;

C figure is an a figure sectional view.

Fig. 3 the utility model gas cartridge.

Referring to Fig. 1: connect two-way valve 3 on the cylinder 1 that sheds spark plug, two-way valve 3 end in addition connects gas cartridge 5 and valve cocks 6 by pressure hose 4.Connect tyre valve core with valve cock during inflation, step motorcycle initiating bar drive piston 2 and move repeatedly, tire can be inflated quickly and easily.

Scheme referring to a-b among Fig. 2: two-way valve is that hexagonal prism, the air inlet valve nozzle 1 of a headband silk mouth screws in the left valve pocket 4, and left spring 3 is contained in left valve pocket bottom, and air inlet steel ball 2 is contained between air inlet valve nozzle 1 and the left spring 3.Exhaust valve nozzle 8 screws in the right valve chamber 7, and exhaust steel ball 5 is contained in the right valve chamber bottom, and right spring 6 is contained between exhaust valve nozzle 8 and the exhaust steel ball 5.9 is valve body.

Referring to Fig. 3: gas is by air inlet tube head 1 in the Cylinder of motorcycle, enter cylindrical shell 2 after foamed plastics filtering material 3 filters,, enter tire through sebific duct, valve cock then by tube head 4 outputs of giving vent to anger, the tube head 4 of giving vent to anger is spun on the cylindrical shell 2 with the silk mouth, changes filtering material 3 so that get.

The utility model working principle is when stepping the motorcycle initiating bar, cylinder body 1 inner carrier 2 is moved to lower dead center by top dead center, the cylinder internal volume becomes the big negative pressure that forms, external atmosphere pressure promotes air inlet steel ball in the left valve pocket, INO, drain tap are closed by right spring and exhaust steel ball effect drain tap in the right valve chamber and are entered fresh air in the cylinder body, when piston 2 by lower dead center when top dead center moves, the compression of cylinder internal volume forms 6-9Kg/cm ²Pressure, this moment, air intake valve was closed as mentioned above, and drain tap is opened, and gas is forced out in the cylinder, and by pressure hose, the gas cartridge valve cock enters tire, reaches the fast aeration purpose.

The utility model is made simple, and is with low cost, little in light weight can the carrying of volume with car, and convenient light and handy during use, the greasy dirt tire does not have promotional value.

Claims (2)

1, a kind of Cylinder of motorcycle that utilizes connects air valve, connects the motorcycle pin that gas cartridge and valve cock form through pressure hose again and steps on aerator, it is characterized in that described air valve is a two-way valve, is equipped with filtering material in the described gas cartridge.

2, step on aerator according to the described motorcycle pin of claim 1, it is characterized in that the suction valve of described two-way valve is made up of air inlet nozzle in the left valve pocket of screw-in and air inlet steel ball and the spring in the left valve pocket; The outlet valve of two-way valve is made up of exhaust nozzle that screws in right valve chamber and exhaust steel ball and the spring in the right valve chamber.
