Building measuring instrument

Abstract

The invention discloses a building measuring instrument, which structurally comprises a supporting table, control buttons, conduction sliding rails, a sliding block, a balance bracket, a laser distance measuring instrument and a balance base, wherein the control buttons are embedded in the upper end surface of the supporting table. According to the invention, magnetisms of magnetic blocks arrangedon clamping plates on the two sides are opposite to improve magnetic adsorption between the clamping plates on the two sides, so that the firmness and the stability of clamping a laser distance measuring instrument by the clamping plates are improved; and a rotor rotates, and outer ring torquers at the upper and lower ends of an outer ring are relatively kept balanced, so that the laser distancemeasuring instrument is kept on the horizontal line, and a laser beam on the laser distance measuring instrument is ensured to be emitted horizontally; a telescopic hose shrinks to achieve a certain buffering effect while the telescopic hose conducts air pressure, at the moment, a pressure dividing groove conducts the air pressure into eight pressure discharging pipes, inclined air spraying is conducted towards the outer side of a bottom plate through an air outlet end of a nozzle, fine sand and stones at the lower end of the bottom plate are blown out, and the horizontal state of the laser distance measuring instrument is improved.

Description

technical field [0001] The invention relates to the field of instruments and meters, and more specifically relates to a building measuring instrument. Background technique [0002] The laser rangefinder measures the distance inside the building room during the construction process. The laser rangefinder emits a laser beam, and the photoelectric element receives the laser beam reflected by the target. The timer measures the time from the launch to the reception of the laser beam, so that Calculate the target distance, but when the laser distance measuring instrument is working, the laser beam must be emitted horizontally. Because the interior of the construction site room is affected by the unstable ground and there are many fine sand and stones on the ground, the laser distance measuring instrument is easy to A certain horizontal angle deviation occurs, which makes the distance of the laser beam longer, which causes the time for the timer to measure the laser beam to be exte...
