Zero-value error calibration device for construction project quality detector

Abstract

The invention discloses a zero-value error calibration device for a construction project quality detector. The device comprises a base, a trimmer, a mounting plate, a turntable, a slider, a support bracket, a calibrator body and a guide rail. The base is N-shaped, wherein two side surfaces are equal, and the bottom is concave. The top surface and the bottom surface of the slider are in interference fit and movably connected to form a convex. The height of both sides of the base is 15cm. According to the invention, the trimmer is arranged; when minor errors are caused by the calibration of thecalibrator body driven by the slider on the guide rail, a rotary knob drives the trimmer body to rotate through the controller; the trimmer body controls the slider to carry out error trimming on theguide rail through a rotation device and a butt joint rod; a lock catch is pressed to prevent the butt joint rod from rotating to move the slider; calibration errors during calibration are avoided; and the calibration effect is effectively improved.

Description

technical field [0001] The invention relates to a zero-value error calibrating device for construction quality detectors, belonging to the field of construction quality detectors. Background technique [0002] Construction engineering refers to the engineering entity formed through the construction of various housing buildings and their ancillary facilities and the installation activities of supporting lines, pipelines and equipment.
