Digital geoid height difference measuring instrument

Abstract

The invention discloses a digital geoid height difference measuring instrument which comprises a bottom supporting rod, a first lug is fixedly installed at the upper end of the bottom supporting rod, a second lug is arranged on the upper side of the first lug, a connecting column is fixedly installed on the right side of the upper end of the first lug, and a rotating groove is formed in the right side of the second lug. And a rotating shaft I is arranged in the rotating groove. According to the digital geoid height difference measuring instrument, the measuring handbook can move up and down through the third movable sleeve, the second rotating shaft, the second movable sleeve, the third locking bolt and the first movable sleeve, then the vertical position of the measuring handbook can be adjusted, and meanwhile the measuring handbook can rotate around the second movable sleeve through the third movable sleeve and the second rotating shaft; the angle of the measuring handbook can be adjusted, the bottom supporting rod can rotate around the first rotating shaft through the first lug seat and the connecting column, then folding storage of the bottom supporting rod and the second supporting rod is achieved, the height of the level gauge can be adjusted through the third supporting rod, design is reasonable, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of electronic level instruments, in particular to a digital geoid height difference measuring instrument. Background technique [0002] Electronic level, also known as digital level, is composed of base, level, single telescopic lens and data processing system. Electronic level is based on automatic leveling level, adding spectroscope and detector to the optical path of telescope, and using striped coding ruler. It is a high-tech product of opto-mechanical integration composed of electronic system for image processing and image processing. [0003] However, most of the existing electronic levels cannot realize the folding and storage of the base, and most of the existing electronic level measuring handbooks can neither realize the adjustment of the vertical position of the measuring handbook nor the angle of the measuring handbook. Adjustment, low practicability, at the same time, most of the existing elect...

Problems solved by technology

[0004] The purpose of the present invention is to provide a digital geoid height difference measuring instrument to solve the problem that most of the existing electronic levels in the above background technology cannot realize the folding and storage of the base, and most of the existing electronic levels The measuring hand book can neither adjust the vertical position of the measuring hand book, nor can it realize the adjustment of the angle of the measuring hand book. The practicability is low. At the same time, most of the existing electronic levels cannot be adjusted in height. problem of use
