Expansion link 204 synchronizing moving in portion, prompt switch device 2 shows different oxygen according to the diverse location that expansion link 204 is in
Force value.
As it is shown on figure 3, oxygen apparatus of oxygen supply 1 includes that shell 107, one end of shell 107 are provided with oxygen supply adaptor 101,
Shell 107 inner hollow, piston rod 104 is arranged on this hollow part, and the other end of shell 107 is provided with seal plug 105.
Being provided with the first restriction protrusion in shell 107, one end of piston rod 104 is provided with the second restriction protrusion, the first limit
Position projection coordinates spacing with the second restriction protrusion；Compression spring 106 it is set with, compression spring 106 one end and the on piston rod 104
Two restriction protrusion contacts connect, and the other end contacts connection with seal plug 105.
The first sealing ring 102 it is provided with between piston rod 104 one end and shell 107；Piston rod 104 other end and seal plug
It is provided with the second sealing ring 103 between 105.
The middle part of oxygen apparatus of oxygen supply 1 is provided with face shield oxygen supply entrance.
As shown in Figure 4, prompt switch device 2 includes the prompt switch shell 201 of hollow, and expansion link 204 is arranged on prompting
Switch housing 201 is internal, is additionally provided with many group display circuits 206, is socketed with multiple outside expansion link 204 in prompt switch shell 201
Position spring 203, expansion link 204 triggers different display circuits 206 when being in diverse location.

Time, contact contacts with the electrode 202 of diverse location, and lights display lamp 205.
Display circuit 206 is provided with no less than 3 groups.
Different display lamps 205 is different color.
Pipeline between high-pressure oxygen cylinder and decompressor is additionally provided with Pressure gauge and turns off valve.
As it is shown in figure 5, in another specific embodiment of the present invention, pressure-detecting device by oxygen apparatus of oxygen supply 1, carry
Show that switching device 2 two parts form.Wherein, the structure of pressure-detecting device includes:
Oxygen apparatus of oxygen supply is used for connecting oxygen, and prompt switch device is connected with oxygen apparatus of oxygen supply, according to oxygen pressure
Size, excite the electrode of diverse location, the state of prompting oxygen pressure.
Oxygen apparatus of oxygen supply is pressure detecting, the parts transmitting oxygen.
Oxygen apparatus of oxygen supply is made up of shell, oxygen supply adaptor, piston rod, compression spring, seal plug and sealing ring.
Oxygen supply adaptor one end is connected to the aircraft oxygen supply interface other end and is connected on shell, by the first sealing ring, second
Sealing ring is respectively arranged in front end and the end of piston rod, is then enclosed within by compression spring on the appointment position of piston rod, uses
Plug seals and carries out spacing to compression spring.First sealing ring is in order to oxygen is pressed with effect concentration, it is ensured that have enough gas
Compression spring is outwards pushed open by pressure, and the effect of the second sealing ring is after oxygen supply is connected, it is ensured that inside oxygen apparatus of oxygen supply gas
Close property, prevents air pressure from revealing.
Operation principle: aircraft oxygen outlet is connected with oxygen supply joint, opens oxygen valve.When the pressure being passed through oxygen
During more than the pressure of compression spring, compression spring is compressed, and piston rod starts to move laterally, when oxygen pressure reaches rated value
Time oxygen supply connect.Along with the difference being passed through oxygen pressure so that the degree of compression spring compression is different, finally makes piston rod
Overhang is the most different, and the overhang of piston rod will affect the difference of prompt switch device instruction.
Prompt switch is a kind of touch switch device, is made up of shell, electrode, expansion link, back-moving spring and display lamp.
Electrode, expansion link, back-moving spring are arranged at the enclosure of prompt switch, and display lamp is arranged on the top of shell
Portion, display lamp is divided into different colors, for pointing out different oxygen pressures, electrode power supply carried by aircraft electrical power supply system
Supply.
Operation principle: expansion link is connected with the piston rod on apparatus of oxygen supply, along with being continuously increased of oxygen pressure, oxygen supply fills
The compression spring put promotes piston rod to move out, and now piston rod is to one inward pressure compression reset bullet of expansion link
Spring, expansion link can shorten along with constantly diminishing of stroke, when back-moving spring is compressed to a certain degree, the contact of expansion link
Touching with electrode, display lamp 1 lights.Along with oxygen pressure is continuously increased, compression spring constantly compresses, and expansion link constantly shortens,
The contact of expansion link disconnects with first group of electrode triggers second group of electrode then, and second group of electrode is triggered, and display lamp 2 is by point
Bright.3rd group is also same reason.
Otherwise, along with the use of crew, when oxygen pressure is more and more less, the back-moving spring in prompt switch device is opened
Beginning to provide restoring force for expansion link, expansion link is the most elongated, and the contact of expansion link departs from second group of electrode, and display lamp 2 extinguishes.
When the contact of expansion link is triggered with first group of electrode, display lamp 1 is connected, it was demonstrated that internal system oxygen pressure is
Oxygen supply being connected, face shield can normally work.
It should be appreciated that for those of ordinary skills, can be improved according to the above description or be converted,
And all these modifications and variations all should belong to the protection domain of claims of the present invention.
