Abstract

The utility model of an inner storage type high pressure air cylinder, which belongs to the technical field of the inflating device, comprises an external cylinder. An external cylinder cover is arranged at the upper end of the external cylinder, and an air container is positioned in the external cylinder. The upper end of the air container is provided with a check valve, and a leather cup is mounted on the upper end of the check valve. A base is installed at the lower end of the air container. By using the inner storage type high pressure air cylinder, the air container cannot be ejected by the air pressure to injure people, can the check valve can be prevented from being blocked.

Description

The internal storage type gas cylinder

The utility model belongs to the technical field of charger.

Now the pump of usefulness all is that a base is housed on a barrel shell, inserts an axle in barrel shell, and a piston is housed on axle, and an external again gas receiver is formed, but external gas receiver causes danger easily, causes the user injured.

The purpose of this utility model provides a kind of gas receiver internal storage type gas cylinder in barrel shell, that can not cause casualties.

This internal storage type gas cylinder comprises urceolus, and cover outside be equipped with the upper end of urceolus is equipped with gas receiver in urceolus, in the upper end of gas receiver one-way valve is housed, and in the upper end of one-way valve leather cup is housed, and in the lower end of gas receiver base is housed.

Because gas receiver is in urceolus, a very important person can push down urceolus, and gas receiver just can not ejected by air pressure and wound the people, can not cause danger, and one-way valve presses off downwards in the upper end of gas receiver, if dirt is arranged in the inflator, all can extrude, and can not cause one-way valve to stop up with air-flow.

Accompanying drawing shows embodiment of the present utility model, wherein:

Figure 1 shows that the front view of internal storage type gas cylinder;

Figure 2 shows that the worm's eye view of internal storage type gas cylinder;

Figure 3 shows that along the sectional view of A--A line shown in Figure 2;

Internal storage type gas cylinder as shown in the figure comprises urceolus 1, and cover 9 outside the upper end of urceolus 1 is bonded with, and is connected with handle 10 on the cover 9 outside.Guiding hoop 8 is housed in the lower end of urceolus 1.Gas receiver 2 is housed in urceolus 1, in the upper end of gas receiver 2 one-way valve 6 is housed, one-way valve 6 comprises valve body 3, and spool 4 is housed in valve body 3, is contained in the cross bar 5 that stops spool 4 in the valve body 3.In the upper end of one-way valve 6 leather cup 13 is housed, leather cup 13 is with holes trapezoidal in the middle of being.In the lower end of gas receiver 2 base 7 is housed, in base 7, is provided with air pipe 12, on base 7, be provided with the pedal stand 11 that is connected as a single entity with base.In use, because the intermediate hole and the unidirectional valve base chamber of leather cup are gapped, when upwards mentioning urceolus, gas passes through from the gap of the intermediate hole of leather cup and unidirectional valve seat, enter outer tube inner chamber, and when urceolus is depressed, the leather cup lower wall tightly is pressed on the check valve body, gas can only be depressed the one-way valve spool and enter from one-way valve, and when mentioning urceolus again, spool is closed under the effect of gas receiver internal pressure, and extraneous gas can only pass through from the gap of the intermediate hole of leather cup and unidirectional valve seat, enter outer tube inner chamber, thereby reach the purpose of inflation.
