Technical field
The utility model relates to technical field of pressure detection, more particularly, to a kind of air respiratorresuscitator integrated control unit
Pressure signal device.
Background technique
The integrated control unit of air respiratorresuscitator is widely used in the industries such as fire-fighting, rescue, to inform that user is present
Pressure in gas cylinder, moreover it is possible to estimate residue according to the gas consumption of user and use the time.Common integrated control unit is also matched
Have mechanical compression table, can make air respiratorresuscitator integrated control unit electricity not enough or use when failure.
The pressure displaying principle of existing product are as follows: mechanical pressure gauge inflates deformation, instruction by theory of mechanics, i.e. bourdon tube
Storage pressure；And digital display screen is then to convert electric signal for pressure signal to indicate gas cylinder pressure by independent pressure sensor
Power.It is had the disadvantage that using the program
1, the pressure sensor cost of a minitype high voltage (0~40MPa range) is at 300 yuan of RMB or so, cost compared with
It is high；
2, each pressure sensor needs 0 point of setting and calibration, time-consuming；
3, because mechanical pressure gauge and pressure sensor have respective measurement error, so that digital display pressure and mechanical pressure gauge
Show pressure unmatched.
Summary of the invention
The purpose of the utility model is to provide a kind of pressure signal devices of air respiratorresuscitator integrated control unit, it has
Cost is relatively low, easily fabricated, and more accurate feature.
The technical scheme adopted by the utility model is the pressure signal device of air respiratorresuscitator integrated control unit, institute
The pressure signal device for stating air respiratorresuscitator integrated control unit includes:
Mechanical pressure gauge, which has the bourdon tube that can be deformed after inflation, and the mechanical pressure gauge has
Digital indication disk and front end are located at the indicator shaft of the digital indication disk center position, and the front end of the indicator shaft is connected with table
Needle；
High pressure air pressure input pipe；
Encoder；
Digital display manometer display；And
The high pressure air pressure input pipe connects the bourdon tube；
The indicator shaft and the bourdon tube match；
The other end of the indicator and the digital indication disk match；
The encoder is connected on the indicator shaft；
The code device signal is connected to the digital display manometer display.
The encoder is mechanical or raster pattern digital encoder.
The utility model is compared to the prior art advantageously: cost is relatively low, easily fabricated, and more precisely.
The mechanical encoder or raster pattern number that the pressure signal device of the air respiratorresuscitator integrated control unit of the utility model uses
Word encoder is commonly used in mouse wheel structure, is easy to purchase, and low in cost.Mechanical encoder and raster pattern number
Acquired rotary angle position signal and dial plate pressure value corresponds encoder at work, does not need as being passed using pressure
Sensor scheme is directed to each pressure sensor like that and carries out 0 point of setting and pressure value calibration, eliminates a large amount of manufacturing man-hours.Together
When, it is not in using pressure sensor side because linking with stem-winder when using on air respiratorresuscitator integrated control unit
For case like that due to respective measurement error, digital display pressure shows the not corresponding problem of pressure with stem-winder.And if use is in essence
When spending more demanding use environment, can be cooperated using high-accuracy mechanical pressure gauge the gear set of different reduction ratio make it is mechanical or
Grating encoder collects the higher electric pressure signal of precision without will increase dramatically product cost.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples:
Fig. 1 is the main view of the pressure signal device of the air respiratorresuscitator integrated control unit of the embodiments of the present invention
Figure；
Fig. 2 is the left view cross-sectional view (digital display manometer display is not shown) of Fig. 1.
In figure:
10, mechanical pressure gauge, 11, digital indication disk, 12, indicator shaft, 13, indicator；
20, high pressure air pressure input pipe；
30, encoder；

Specific embodiment
Embodiment is seen figure 1 and figure 2: the pressure signal device of air respiratorresuscitator integrated control unit, comprising: mechanical
The components such as pressure gauge 10, high pressure air pressure input pipe 20, encoder 30, digital display manometer display 40.
Wherein:
The mechanical pressure gauge 10 has the bourdon tube (being not shown on figure) that can be deformed after inflation.Meanwhile the mechanical pressure
The indicator shaft 12 that there is table 10 digital indication disk 11 and front end to be located at 11 center of digital indication disk, the indicator shaft
12 front end is connected with indicator 13.The indicator shaft 12 and the bourdon tube match；The other end of the indicator 13 and the digital indication
Disk 11 matches.That is, being same as the prior art, after gas enters in the bourdon tube, which is deformed, the indicator shaft 12
It is twisted after sensing the deformation of the bourdon tube, rotates the indicator 13, by the cooperation of the indicator 13 and the digital indication disk 11,
Learn air pressure.
The digital display manometer display 40 and the mechanical pressure gauge 10 are preferably secured to together.
The high pressure air pressure input pipe 20 connects the bourdon tube.That is, gas, which is pressed into tracheae 20 via the high pressure gas, enters the wave
Pause pipe.
The encoder 30 can be mechanical or raster pattern digital encoder, and the encoder 30 is connected to the indicator axis
On bar 12.The mode of connection may is that when using raster pattern digital encoder, since raster pattern digital encoder operates nothing
The method of hole axle tight fit can be used to connect in damping, and raster pattern digital encoder is hole, and indicator shaft 12 is axis；Work as use
When mechanical encoder, since mechanical encoder operating has damping, the method that hexagonal shaft cooperation hexagonal hole can be used is come
Connection, mechanical encoder are hexagonal hole, and indicator shaft 12 is hexagonal shaft.Certainly, using raster pattern digital encoder
When, the cooperation of hexagon hole axle can be used also to connect.In addition, can also be connected with the methods of glue bonding, ultrasonic bonding, riveting
Connect the gauge hole of indicator shaft 12 and encoder 30.30 signal of encoder is connected to the digital display manometer display 40.That is,
When the bourdon tube of the mechanical compression table 10 inflates deformation, which just drives the encoder 30 to rotate to corresponding to pressure value
Angle position can be passed without using pressure by the corresponding pressure dependence in encoder rotational angle position being previously set
Digital pressure signal is collected under conditions of sensor and is shown on the digital display manometer display 40.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
Equivalent structure or equivalent flow shift made by using the description of the utility model and the drawings, is directly or indirectly transported
Used in other related technical areas, it is also included in the patent protection scope of the utility model.
