Abstract
The utility model relates to a piston-type tyre inflating valve plunger, which relates to an inflating device which is installed in a vehicle tyre air valve and used for inflating and sealing tyres. The piston-type tyre inflating valve plunger is composed of an air inlet pipe and a piston, wherein, the upper end of the air inlet pipe is open, and the lower end is provided with a piston cavity; the middle part of the air inlet pipe is provided with an air valve; air inlet holes are arranged on the bottom end and the side walls of the piston cavity; the piston which is cylindrical is installed in the piston cavity and can move up and down in the piston cavity. When the piston-type tyre inflating valve plunger is used for inflation, the piston moves down, and compressed air enters an inner tube though the air inlet holes; after the inflation is finished, compressed air in the inner tube makes the piston to move up and close the air valve. The utility model has the advantages of simple structure, labor saving for inflation and favorable sealing performance and is especially suitable for being used as an inflating device for various inflated tyres.
Description
The utility model relates to a kind of tire gas that is installed in and is used in chewing to the tire inflation and makes it the leak free gas filled device.
Cycle tyre, cycle tyre etc. are inflation tyre, have gas on its inner tube of a tyre and chew and be equipped with gas filled device, by gas filled device can be in the inner tube of a tyre charged pressure air and make it sealing.Gas filled device of the prior art adopts the structure of plunger overcoat valve inside more.The upper end open of car door pin has the pore that feeds the inner tube of a tyre on the sidewall of lower end; Valve inside is made by thin latex, is sleeved on the plunger lower end and works in coordination with induction opening.During inflation, pressure air is washed valve inside open and is entered the inner tube of a tyre through induction opening; After the inflation, valve inside relies on tire internal pressure air that the plunger induction opening is sealed.Though the gas filled device of said structure is simple in structure,, be easy to cause tire to become flat because of aging breaking because the fuel resistance of latex valve inside is poor.In addition, the inflation resistance ratios is bigger, relatively requires great effort during the manual inflation.
The purpose of this utility model promptly is the improvement suitable in addition to the structure of Tyre inflating device, to improve its sealing property and to make inflation more laborsaving.
To achieve these goals, the utility model is set up a plunger shaft and is utilized moving of piston to realize the switching of valve in the lower end of plunger.Be described in further detail below in conjunction with the technical characterictic of specific embodiment the utility model piston type tire plunger.
Accompanying drawing 1 is the structural representation of the utility model piston type tire plunger.
With reference to the accompanying drawings 1, the utility model piston type tire plunger mainly is made of air inlet pipe and piston.Air inlet pipe 1 is a tubular, its upper end open, and the lower end has a plunger shaft 2, the valve 3 of its middle part for being communicated with plunger shaft and working in coordination with piston.Air inlet pipe is installed in during tire gas chews by seal ring 4, has the induction opening 5 that is communicated with the inner tube of a tyre on the bottom of plunger shaft and the sidewall.Piston 6 is cylindrical, is made by rubber, is installed in the plunger shaft 2 and can moves up and down therein.During inflation, pressure air makes descent of piston, and valve is opened, and pressure air enters the inner tube of a tyre by induction opening; After the inflation, tire internal pressure air makes piston stroking upward and valve is sealed.
The utility model is simple in structure, inflates laborsavingly, and good seal performance is so be particularly suitable for gas filled device as various inflation tyres.
