Aneroid barometer

Abstract

The invention provides an aneroid barometer. The aneroid barometer comprises a barometer body, pins, a screw cap and a threaded connection column; the top surface of the barometer body is in threadedconnection with the screw cap; the two pins which have ring-shaped structures are separately arranged on the front and rear parts of the outer wall of the barometer body; the threaded connection column with a certain length is arranged on the bottom surface of the barometer body; the outer side of the threaded connection column is further matched with a metal outer screw sleeve in a threaded connection manner; four ball head levers are uniformly distributed on the outer wall of the metal outer screw sleeve; four scale marks are uniformly distributed on the outer wall of the metal outer screw sleeve; and a drilling section which is integrated with the metal outer screw sleeve is arranged on the bottom surface of the metal outer screw sleeve. The problem that a certain testing point in a necessarily measured geological environment is not level is solved. The screw cap is mounted on the head and positioned on the top of the barometer in a threaded mode, dust prevention treatment is carried out by the screw cap, and the circumstance that dust or sand exists when the ground is drilled to damage the head of the barometer is avoided.

Description

technical field [0001] The invention belongs to the technical field of air pressure instrument structure, and in particular relates to an aneroid air pressure gauge. Background technique [0002] Aneroid barometer is a kind of atmospheric pressure measuring instrument which is induced by deformation element. It has the advantages of convenient portability, accurate measurement, wide range of pressure measurement, easy operation and maintenance, and no mercury pollution. Widely used in meteorology, military, aviation, navigation, agriculture, surveying, geology, industrial and mining enterprises and scientific research and other fields. [0003] Based on the above, the applicant found that some existing aneroid barometers, especially the aneroid barometers used in the geological exploration process, need to be laid flat when the barometer is used to detect the geological environment, so as to obtain higher accuracy However, the complexity of the geological environment makes...

Problems solved by technology

[0003] Based on the above, the applicant found that some existing aneroid barometers, especially the aneroid barometers used in the geological exploration process, need to be laid flat when the barometer is used to detect the geological environment, so as to obtain higher accuracy The detection data, and the complexity of the geological environment, it is difficult to make the surface contact with the ground horizontally, which affects the final detection of various data and the accuracy of the experimental conclusion
