CN2268128Y - Simple double-function bicycle inflator - Google Patents

Abstract

The utility model relates to a simple double-function bicycle inflator which is a double-function inflator which can be used for inflating a bicycle and can be used for illumination. The simple double-function bicycle inflator overcomes the disadvantages of a traditional inflator of bulkiness, laboursome operation and easy rustiness. A cylinder body of the inflator and a handle of the inflator both adopt plastic elements. An inflator nozzle uses a big rubber ferrule. At the time of inflation, the inflator nozzle can be directly sheathed on an air valve to ensure good sealing performance, smooth air intake and convenient use. The utility model has the characteristics of light weight, surface luster, free maintenance, portability, etc. The rear end of the handle is connected with a small electric torch by threads for convenient illumination for users.

Description

Easy difunctional pump voluntarily

The utility model is a kind of difunctional inflator that can be used as illumination to the bicycle inflation again.

Traditional mechanical bicycle inflator major part is made with iron and steel.Type mainly contains monotubular and band adds the bitubular inflator of pressure cylinder, and the main problem that exists is that volume is big, Heavy Weight, use inconvenience (many womans that wear skirt are difficult to use), carry difficulty.Though some inflator can carry with car, can too complicated, cost is higher, and actual the use has little significance, as Chinese patent CN85203300, CN85203464, CN8620514 etc.

The purpose of this utility model be to change that traditional pump volume is big, Heavy Weight, use inconvenience, carry shortcoming such as difficulty provide a kind of can again can be as the difunctional inflator of illumination to the bicycle inflation.

The purpose of this utility model is achieved in that the cylindrical shell of inflator and handle all adopt plastic castings, handle rear end is with the little torch that is threaded, the inflator outlet nozzle adopts big rubber washer, directly overlap during inflation and be pressed on the valve inside, avoided being connected of conventional pump long tube commonly used and clip and valve inside, good seal when guaranteeing to inflate, air inlet are smooth and easy, easy and simple to handle.

Fig. 1 is the overall structure figure according to the concrete device that the utility model proposes.

The piston (10) that this device is made up of piston ring (1), piston seat (2), inflating rod (4) and end cap (5) also passes through valve (11) exhaust at the inboard pressurized air of twitching of cylindrical shell (3), this valve is made of sealing rubber ring (8), clamping nut (9), and handle (6) not only is fit to handle but also can conveniently throws light on by being threaded with little torch (7).

Fig. 2 is a schematic representation of fixing the fastener of this device, is made up of snap ring (14) and thimble (15).

Fig. 3 is the position view of this device when carrying with car, realizes the location by thimble (14) and cylindrical shell (3).

The structural design on inflator top had both made things convenient for when inflating with finger directly fixing, helped when carrying with car again and being connected and fixed of bicycle tripod; The tightening position of the thimble (14) on the center hole when carrying with car on inflator top and the handle (13) and the fixing inflator fastener is to realize by the spring in the inflator handle (12), and the structure on inflator top makes inflator and bicycle tripod keep excellent contact to locate again simultaneously.

The design of this model utility is ingenious, simple in structure, easy to carry (can be with car, again can with oneself), reliable performance, simple to operate.Make the utlity model has in light weight, volume is little, any surface finish, avoid safeguarding and using simple function, and can also be at any time as illumination.

Claims (1)

1. easy difunctional bicycle pump is characterized in that: directly overlap the clamping nut (9) that is pressed on the valve cock when outlet nozzle of this device has adopted sealing rubber ring (8) and inflation.
