Abstract
The utility model discloses an inflator with pressure indicator, used for inflation of bicycles and handcarts. A pressure gauge is installed on an air cylinder of the inflator. An air outlet hole of a main inflator is connected with a check valve which is fixed inside the air cylinder. The air cylinder is provided with an air outlet hole which is communicated with an exhaust pipe. The inflator can accurately and duly display the pressure, and can manually control the inflation pressure according to specific circumstances.
Description
The utility model is used to bicycle, wheelbarrow to inflate.
The pump that uses in the daily life does not now have pressure-display, can only be when inflating with sensation, and armrest is determined the degree of inflating by tire, makes inflation pressure uncontrollable.This just causes inflation too much or few easily, influences cyclist's the comfortable feel and the working life of tire.
The purpose of this utility model is to overcome the shortcoming that above-mentioned pump exists, and provides a kind of with the pump that shows pressure.
The purpose of this utility model is to realize like this.On former gas receiver, increase a pressure gauge and check valve.The air outlet hole and the check valve of main inflator join, and check valve is fixed in the gas receiver, and gas receiver has air outlet hole, communicate with outlet pipe, and pressure gauge is connected with gas receiver.
During use, air with the check valve valve open, enters gas receiver by main inflator, and pressure gauge shows pressure, and gas enters outlet pipe from the air outlet hole of gas receiver, enters the wheel tyre cavity again.Pressure gauge can promptly and accurately show force value, and the user can control inflation pressure as the case may be fully artificially during application, no longer blindly inflation.When inflating for bicycle, preceding tire pressure is 0.25～0.3MPa, and when back tire pressure was 0.35～0.4MPa, people's comfortable feel was best, and the working life of tire is also longer.This pump of pressure that shows has brought convenience to life.As to select the pressure gauge range for use be 0～0.6MPa, and grade of accuracy is 2.5 grades, and check valve is that the inflation that rubber type just can satisfy Regular Bicycle tire, wheelbarrow tire etc. is used.Change the form (as ball type) of check valve, can show high object inflation requiring pressure stability.If the pressure gauge range is changed into 0～1MPa, can inflate with interior object 1MPa.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model
1, main inflator, 2. pressure gauge, 3. gas receiver, 4. check valve, 5. base, 6. outlet pipe.
Adopt former main inflator and exhaust pipe structure, on gas receiver, adorn the pressure gauge that a range is 0～0.6MPa, grade of accuracy is 2.5 grades, the air outlet hole and the check valve of main inflator join, check valve is contained in the gas receiver, be fixed on the base, the gas receiver bottom has an air outlet hole to communicate with outlet pipe by base.Can be used for bicycle inflates.
