Abstract
The utility model discloses a vacuum barometer, including the watchcase, its characterized in that: the watchcase outer wall on be connected with erection joint, inner wall on fixed mounting have the core, have dial plate, core to include pointer and negative pressure elastic element through screw fixed mounting on the core, install the reference column on the dial plate, the watchcase is holistic obturator, its upper end is manometer display surface, transparent setting. The utility model has the advantages of reasonable design, make convenient to use, the current barometer of sensitivity higher more accurate, life is longer, all can keep good operating condition under various rugged environment, can not influence the use of instrument because of the environment, makes it to have more extensive usage space.
Description
technical field:
The utility model relates to rain glass field, particularly a kind of baro-vacuum gauge.
background technology:
Rain glass, the one of instrument instrument is for helping to judge possible Changes in weather and determining a kind of instrument of the height risen, and is that the film sylphon made using elastic metallic is as sensing element, gaseous tension is converted to the elastic displacement of sylphon by it, drives pointer by lever and gear train; When clockwise direction deflects, pointer just indicates the variable quantity that air pressure raises, otherwise, when pointer counterclockwise deflects, indicate the variable quantity that air pressure reduces.When the elastic stress of sylphon and gaseous tension balance each other, pointer just stops operating, and the atmospheric pressure value at this moment indicated by pointer is exactly tested gas pressure value at that time.
utility model content:
The purpose of this utility model is that structure is more reasonable, manufactures baro-vacuum gauge easy to use.
The technical solution adopted in the utility model is:
Baro-vacuum gauge, comprise watchcase, it is characterized in that: described watchcase outer wall is connected with on erection joint, inwall and is installed with movement, movement is mounted by means of screws with dial plate, movement comprises pointer and negative pressure flexible member, dial plate is provided with reference column, watchcase is overall obturator, and its upper end is tensimeter display surface, transparent setting.
Described baro-vacuum gauge, is characterized in that: described watchcase fixedly mounts the movement of its inside by watchcase screw, and erection joint is provided with external thread.
Compared with prior art, the beneficial effects of the utility model are:
The utility model reasonable in design, manufacture easy to use, higher more accurate, the longer service life of the more existing rain glass of sensitivity, all can keep good working order under various rugged environment, the use of instrument can not be affected because of environment, make it to have usage space widely.
accompanying drawing illustrates:
Fig. 1 is the utility model structural representation.
embodiment:
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail:
Baro-vacuum gauge, comprise watchcase 1, watchcase 1 outer wall is connected with on erection joint 2, inwall and is installed with movement 3, movement 3 is installed with dial plate 5 by screw 4, movement 3 comprises pointer 6 and negative pressure flexible member 7, dial plate 5 is provided with reference column 8, watchcase 1 is overall obturator, and its upper end is tensimeter display surface 9, transparent setting, watchcase 1 fixedly mounts the movement 3 of its inside by watchcase screw 10, and erection joint 2 is provided with external thread.
Above-described embodiment is only preferably embodiment of the present utility model, and in addition, the utility model can also have other implementations.It should be noted that, under the prerequisite not departing from the utility model design, any apparent improvement and modification all should fall within protection domain of the present utility model.
