Abstract

The utility model relates to a tire pressure setting automatic inflation device, which solves the problem that the existing tire inflation tool is not convenient to operate, and is time-consuming and labor-consuming. The tire pressure setting automatic inflation device comprises an inflation tube, and a handle and an air pressure dial scale which are arranged on the inflation tube; after passing through the air pressure dial scale, the inflation tube is divided into two paths which are respectively a regulating tube and an air inlet tube, and the outlet of the air inlet tube is connected with an air inlet nozzle; the end of the regulating tube is connected with a bolt through inner thread; the top of the bolt is provided with the preset air pressure dial scale for setting the air pressure to be reached; the bottom of the bolt in the regulating tube is provided with a spring hanger, one end of a spring is connected with the spring hanger, and the other end thereof is connected with a piston; the side wall of the regulating tube is vertically provided with an exhaust tube communicated with the regulating tube, and the outlet of the exhaust tube is connected with an exhaust nozzle; and the inner side wall of the regulating tube under the exhaust tube is smooth, and the inner side wall of the regulating tube upon the exhaust tube is provided with thread. The tire pressure setting automatic inflation device is convenient to operate and easy to regulate air pressure, and can prolong the service life of the tire.

Description

Tire pressure is set self-filler

Technical field

The utility model relates to Tire Inflation System, is specifically related to a kind of tire pressure and sets self-filler.

Background technology

At present, existing manual tire inflatable tool on the market, need during inflation manually by holding up, eyes will be paid close attention to compression indicator and see whether reach required pressure simultaneously, but because handle is decontroled in the restriction of people's self speed of response again when seeing that gauge hand points to required scale, hyperinflation perhaps, if before the required scale of pointed, decontrol handle, again may the required pressure of out of reach.It is very inconvenient to operate like this, and time-consuming effort again, the most important thing is to be difficult to reach the needed standard pressure of tire, has reduced the service life of tire.

Summary of the invention

The utility model provides a kind of tire pressure to set self-filler at the deficiencies in the prior art.

The utility model comprises appendix, and appendix is provided with handle, baroscale dish, and the appendix behind the baroscale dish is divided into two-way, is respectively adjustable pipe and air inlet pipe, and the exit of air inlet pipe taps into valve; The adjustable pipe end is connected with screw by negative thread, and the screw top is provided with default baroscale dish, is used for setting the atmospheric pressure value that will reach.Screw bottom in adjustable pipe is provided with spring hanger, and an end of spring is connected with spring hanger, and the other end is connected with piston; Be vertically installed with the freeing pipe that is communicated with adjustable pipe on the sidewall of adjustable pipe, valve runs in the exit of freeing pipe; The adjustable pipe madial wall of freeing pipe below is smooth, and the adjustable pipe madial wall of freeing pipe top is threaded.

The utility model has increased an exhaust gear on the gas piping of existing manual Tire Inflation System.During inflation, set default baroscale value by the rotation up and down of screw earlier, when the pointer of baroscale dish does not reach default scale, the piston that links to each other with spring can rise gradually owing to the pressure effect of gas, but remain at the below of freeing pipe, and when atmospheric pressure value reached default scale and continues to raise later on, piston will rise to more than the freeing pipe, and freeing pipe carries out exhaust.Even without the instant gas filled device of extracting, the air pressure in the tire just remains on this value after reaching barometric standard pressure like this.

The utility model has overcome when existing manual gas filled device is inflated operates inconvenience, time-consuming, the inaccurate disadvantage of charged value.This gas filled device design science, rational in infrastructure, easy and simple to handle, structure is small and exquisite, has increased the service life of tire, be gas filed preferred embodiment such as the tire of automobile, locomotive, bicycle and ball, rubber boat.The utility model investment is little, and income is big, and market outlook are considerable.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the scheme drawing of default baroscale dish among Fig. 1.

The specific embodiment

As depicted in figs. 1 and 2, the utility model comprises appendix 1, and appendix 1 is provided with handle 2, baroscale dish 3, and the appendix behind baroscale dish 3 is divided into two-way, is respectively adjustable pipe 7 and air inlet pipe 4, and the exit of air inlet pipe 4 taps into valve 5; Adjustable pipe 7 ends are connected with screw 12 by negative thread, and screw 12 tops are provided with default baroscale dish 13, are used for setting the atmospheric pressure value that will reach.Screw 12 bottoms in adjustable pipe 7 are provided with spring hanger 11, and an end of spring 10 is connected with spring hanger 11, and the other end is connected with piston 6; Be vertically installed with the freeing pipe 8 that is communicated with adjustable pipe on the sidewall of adjustable pipe 7, valve 9 runs in the exit of freeing pipe 8; Adjustable pipe 7 madial walls of freeing pipe 8 belows are smooth, and adjustable pipe 7 madial walls of freeing pipe 8 tops are threaded.

Working process of the present utility model is: before the inflation, set default baroscale value by the rotation up and down of screw earlier.During inflation, air-flow arrives the baroscale dish through appendix and flows to adjustable pipe and air inlet pipe, constantly pushes at operating personal under the effect of handle, and the value of baroscale dish rises gradually.When the pointer of baroscale dish did not reach default scale, the air pressure in the air inlet pipe was greater than the air pressure in the tire, and air-flow puts on the air to tire through air inlet pipe, and the piston that links to each other with spring simultaneously is owing to the effect of air pressure is risen gradually, but remained on the below of freeing pipe.When atmospheric pressure value reaches default air pressure and when not stopping to inflate, piston will rise to more than the freeing pipe, freeing pipe carries out exhaust, and simultaneously because the effect of freeing pipe, air inlet pipe equates with atmospheric pressure value in the tire, stops to inflate.Even without the instant gas filled device of extracting, the air pressure in the tire reaches and remains on barometric standard pressure like this, has overcome the inconvenience of existing manual gas filled device.
