Abstract

The utility model relates to a vehicle following tool used for inflating a bicycle tire. The utility model calls an inflator which is composed of an inflator body which is inserted into a vertical pipe of a bicycle, a saddle pipe which is provided with an axial sealing ring and a one-way valve is inserted into the upper part of the inflator body, a piston is arranged at one end of a pull rod in a reverse direction, the pull rod, a handle and a hose. The inflator and a bicycle body are integrally combined, and the inflator which is carried on a vehicle does not occupy space. The utility model which is not easily stolen has labor saving of the pull rod to inflate, and the inflating amount is large. The utility model causes a rider to complete inflating a tire at any time, and becomes a practical bicycle following tool.

Description

Inflator

The utility model relates to a kind of driver's tool that is used for bicycle tyre inflation usefulness.

Existing bicycle pump, its structural limitations as a kind of function of driver's tool.Once on vehicle body, placed in the past reaching purpose as driver's tool, but very easily stolen.Small-sized pen type pump also occurred, though easy to carry, aeration quantity is minimum, lacks practicability, is difficult to promote.The pump that is contained in the saddle pipe is also arranged recently, but higher because of saddle pipe, adopt traditional mode of giving vent to anger of suppressing, firmly inconvenience is used limited.

The design's purpose provides the driver's tool of a kind of bicycle tyre inflation usefulness, and it not only has the aeration quantity of common pump, also can be contained in the vehicle body, is integrated with vehicle body, inflates laborsavingly, is difficult for stolen again.

The design's purpose is achieved in that the stack shell with back cover not inserts in the standpipe of bicycle, and piston reverses direction is installed in an end of pull bar, inserts in the stack shell; The saddle pipe that will have axial seal ring and one-way valve inserts stack shell top.The pulling pull bar is drawn by the one-way valve of gas from the saddle pipe of top of tension and compression, is pressed in the tire by flexible pipe.Like this, finished aerification function with the tension and compression mode.Product with the design makes is called Inflator.

Owing to adopt such scheme, inflator and frame are combined into one, carry with car and do not take up room, be difficult for stolenly, draw gas laborsaving, aeration quantity is big, has solved the demand that the bicycler finishes Tyre inflating at any time.

Below in conjunction with drawings and Examples, the design is described in detail.

Fig. 1 is the design's embodiment's a sectional view.

Among the figure, 1 is standpipe, and 2 is stack shell, and 3 is piston, and 4 is one-way valve,

5 is saddle pipe, and 6 are the axial seal ring, and 7 is pull bar, and 8 is handle, and 9 is flexible pipe.

In Fig. 1, the stack shell of back cover (2) is not inserted in the standpipe (1) of frame, piston (3) oppositely is installed in the lower end of pull bar (7); On the top of saddle pipe (5) axial seal ring (6) is housed, in the middle part perforate of saddle pipe (5) and load onto one-way valve (4), insert in the axial seal ring (6) on saddle pipe (5) top the upper end that the pull bar (7) of piston (3) will be housed, with the top of saddle pipe (5) with the combiner insertion stack shell (2) of pull bar (7); Seal with sealing material with the portion that mutually combines of saddle pipe (5) at standpipe (1), stack shell (2); Handle (8) is installed in the upper end of pull bar (7), and pulling handle (8) makes on the piston (3) and moves pressurized air, and pressurized air is introduced in the tire by the flexible pipe (9) that is connected on the valve port from one-way valve (4), finishes gas replenishment process.

Claims

1, a kind of driver's tool of bicycle tyre inflation usefulness, the design is called Inflator, mainly be made up of stack shell, saddle pipe, piston, axial seal ring, one-way valve and pull bar, it is characterized in that: piston reverses direction is installed in an end of pull bar, and axial seal ring and one-way valve are housed in the saddle pipe.

2, by the described Inflator of claim 1, it is characterized in that: stack shell is the thin walled tube of back cover not.

3, by the described Inflator of claim 1, it is characterized in that: stack shell inserts in the frame standpipe, with the sealing material sealing, is combined into one structure with frame between stack shell and standpipe.
