Abstract

The utility model discloses a safety pump which relates to a tyre inflation device, comprising a pressure piston, an air cylinder body, a pedal ring, an air storing chamber, a pressure gauge, an air pipe, and a nozzle. The safety pump is characterized in that the safety pump is improved on the basis of a general inflator; the pressure gauge is arranged on the air storing chamber; the size of air pressure which is filled in an indication tyre ensures normal working air pressure in the tyre. The utility model is also suitable for airtight and watertight tests.

Description

The safe hit inflator

The utility model relates to aerating and give a kind of aerator of tire, more particularly, what relate to is a kind of safe hit inflator, says more popularly, is exactly pump.

Please refer to Fig. 1, as everyone knows, device to inflations such as bicycle, motorcycle, tricycles commonly used, be with manual pump, the advantage of this pump is: simple in structure, applicability is good, and is easy to use, thereby be generalized to huge numbers of families, become the necessary article that bicycle, tricycle, motorcycle etc. need the equipment of inflation.But also have defective, its defective is to lack a barometer on its pump, owing to lack the barometer that an indication adds the air pressure size, how many inflations in the tire is difficult to conclude, normal excessive, the tire blow-out of pressurization that occurs, it is very few pressurization also to occur, and tire is fragile, frictional force is big, and car runs unhappy.Add normal operating air pressure and grasp to tire, in pressure process, beat several therapeutic methods to keep the adverse qi flowing downward and go again to touch tire with sensation, and so extremely inconvenient, and be difficult to required in hand air pressure size, and explosion tire phenomenon also often appears, be difficult to accomplish " safety " inflation.

The purpose of this utility model is to have the defective that inflator exists for overcoming, and a kind of safe hit inflator is provided, it can indicate the size that adds atmospheric pressure, can ensure that tire adds normal operating air pressure, overcome the phenomenon of blowing out, and can also do the test etc. of airtight, water tightness to the equipment that family uses.

For achieving the above object, the technical solution adopted in the utility model is such:

It is improved on the basis of general high voltage inflator that the utility model safety adds inflator, and this inflator comprises air-storage chamber 5, inflator body 2, pressure piston 1, step circle 3, barometer 6, pneumatic tube and connects chews 4, it is characterized in that a scope is 0～10kg/cm ²Barometer be installed on the air-storage chamber, be used in the aerating process, indicate the air pressure size in the pressurized tire at any time.

Obviously, the advantage of this safe hit inflator is:

One, in pressure process, can grasp tire internal air pressure size constantly, can not produce the phenomenon of blowing out, also the phenomenon that tire adds unsaturated vapor can not take place, ensure the normal use of tire;

Two, because pressure gauge has been installed, in the aerating process, after not needing to beat several therapeutic methods to keep the adverse qi flowing downward, go to test the size of air pressure that tire adds, can at a dash tire be filled up normal barometric pressure, accelerate the speed of inflating like this, be easy to use.

Three, because pressure gauge has been installed, can do airtight, the close test of liquid, the utility model is further described below in conjunction with drawings and Examples to general equipment:

Fig. 1 is existing pump schematic representation;

Fig. 2 is the schematic representation of the utility model safe hit inflator;

Fig. 3 is that A on Fig. 2 is to view;

From Fig. 1 and Fig. 2, compare as seen, each represented parts are equipped with on air-storage chamber the barometer 6 among Fig. 2, represented parts are with to be connected situation identical on remaining part and Fig. 1, different is that a barometer 6 is installed in air-storage chamber 5 upper ends, the air-storage chamber lower end connect a pneumatic tube and connect chew 4, barometer 6 and pneumatic tube and connect and chew 4, be communicated with air-storage chamber 5, pneumatic tube and connecing is chewed and is communicated by the tire of aerating or underproof equipment.Therefore, barometer, pneumatic tube, tire or underproof equipment three are communicated with air-storage chamber, and barometer just can accurately detect tire or by the air pressure numerical value of institute's filling in the test equipment like this.

Embodiment confirms, though this technological scheme just increases by one as the barometer that detects inflation pressure on air-storage chamber, intactly constitute one both inflatable, can detect the device of inflation effect again at once, this device is practical, simple, convenient.

Claims

1, a kind of safe hit inflator comprises air-storage chamber (5), inflator body (2), pressure piston (1), step circle (3), pneumatic tube and connects and chews (4), barometer (6), it is characterized in that air-storage chamber (5) goes up 0～10kg/cm of peace ²Barometer (6).
