Embodiment
The technical solution of the utility model is further illustrated below in conjunction with drawings and Examples.
The utility model provides a kind of measuring instrument for measuring air pressure and height above sea level, comprise by an enclosed cavity of housings close, described housing is provided with the transparent region of band height above sea level dial barometer, the Part I of described enclosed cavity is marked with liquid, part outside described enclosed cavity Part I is vacuum or close to vacuum, the region at least partially of described housing is elastic medium district, elastic deformation is there is under the pressure differential that described elastic medium district produces when described measuring instrument external pressure change, drive described enclosed cavity volume change, and then the liquid level in described enclosed cavity is changed and is presented on described height above sea level dial barometer.
See Fig. 1 to Fig. 3, as the first embodiment, described housing comprises a main body 111 and is positioned at upper end cover 112 and the bottom end cover 113 at main body about 111 two ends, described upper end cover 112, bottom end cover 113 and main body 111 form described enclosed cavity 130, described upper end cover 112 and bottom end cover 113 are by support bar 140 support and connection, the main body 111 of described housing is elastic medium district, described main body 111 is provided with the transparent region 114 of band height above sea level dial barometer, past lower part in described enclosed cavity 130 is marked with liquid 150, and remainder is vacuum or close to vacuum.
In a first embodiment, the main body 111 of housing can select a kind of resilient thin walled shell, such as transparent plastics, and it is subject to different pressure and can deforms.A certain amount of water (or other liquid 150) is housed inside enclosed cavity 130, and a part is pumped into vacuum (or close to vacuum) in addition.When the measuring instrument of this form is positioned at different sea level elevations, because the pressure of cavity is different with the atmospheric pressure of outside, therefore, the main body 111 of housing can deform, therefore the liquid level of water have also been changed, read liquid level by graduation apparatus, also just read the height above sea level when position or air pressure.
With reference to figure 4 to Fig. 9, as the second embodiment, described housing comprise front shroud 115, back shroud 116, connect described front shroud 115 and back shroud 116 Flexible Connector 117, be positioned at the upper bed-plate 118 of upper end, be positioned at the lower bottom base 119 of lower end, described front shroud 115, back shroud 116, Flexible Connector 117, upper bed-plate 118, lower bottom base 119 form described enclosed cavity 130, described front shroud 115 is provided with the transparent region 114 of band height above sea level dial barometer, past lower part in described enclosed cavity 130 is marked with liquid 150, and remainder is vacuum or close to vacuum.
In a second embodiment, the Flexible Connector 117 of elastic deformation can be equivalent to the elastic medium district of housing, be filled with certain water (or other liquid 150) inside enclosed cavity 130, vacuum (or close to vacuum) is pumped in remaining space.Like this, along with the rising of height above sea level, the reduction of air pressure, pressure reduction between pressure in the air of measuring instrument present position and cavity reduces, therefore will there is deformation in Flexible Connector 117, distance between front and rear cover plate 116 will become large, and the height of liquid level will decline, and just can read local pressure or sea level elevation according to graduation apparatus.
With reference to figures 10 to Figure 15, as the 3rd embodiment, described housing comprises elastic diaphragm capsule 121, is located at the sealing plug 123 on the transparent pipe 122 be communicated with on described elastic diaphragm capsule 121 and with it, closed described transparent pipe 122 top, described elastic diaphragm capsule 121, transparent pipe 122, sealing plug 123 form described enclosed cavity 130, described transparent pipe 122 is provided with height above sea level dial barometer (not marking in figure), what show in Figure 10 and Figure 11 is be arranged on by graduation apparatus on backboard 160, this be located on transparent pipe 122 without substantial differences.Past lower part in described enclosed cavity 130 is marked with liquid 150, and remainder is vacuum or close to vacuum.
In 3rd embodiment, described housing has the elastic diaphragm capsule 121 that can be out of shape, be filled with certain water (or other liquid 150) in enclosed cavity 130, a part is pumped into vacuum or close to vacuum in addition.When the measuring instrument of this form is positioned at different sea level elevations, because the pressure of cavity is different with the atmospheric pressure of outside, elastic diaphragm capsule 121 deforms, and therefore liquid level also can change, and just can read height above sea level or the air pressure of working as position by graduation apparatus.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the utility model is described, and be not used as restriction of the present utility model, as long as in spirit of the present utility model, all will drop in Claims scope of the present utility model the change of above embodiment, modification.
