Wall thickness measuring device easy to stretch and contract

Abstract

The invention relates to the technical field of building measurement and discloses a wall thickness measuring device easy to stretch and contract. The wall thickness measuring device easy to stretch and contract comprises a slide bar, wherein the bottom of a top plate is movably connected with a connecting rod; the bottom of the connecting rod is movably connected with a contact block; the middleportion of the slide bar is movably connected with a toothed column; the upper end of the slide bar close to the left side of the toothed column is movably connected with a telescopic device; the leftand right sides of the bottom of a positioning seat are movably connected with two springs; the telescopic device includes a circular block, a cylindrical head, a rotating handle, a base, an annulartrack, and a gear; the cylindrical head is in toothed connection to the annular track; and the gear is movably connected to the right end of the annular track and is in toothed connection to the toothed column. The wall thickness measuring device easy to stretch and contract is simple in structure and accurate in readings by means of the cooperation of the slide bar, the top plate, the connectingrod and the contact block, and is easy to operate by the cooperation of the cylindrical head, the circular track, the gear and the toothed column.

Description

technical field [0001] The invention relates to the technical field of building measurement, in particular to a wall thickness measuring device that is easy to expand and contract. Background technique [0002] In the process of building measurement, the amount of personnel and equipment required is extremely large, and the working environment is poor and the labor intensity is high. The measurement personnel cannot perform multiple tests at the same time. During the wall thickness test process, due to poor measurement conditions on the construction site Various types of walls have different thicknesses, and construction companies have strict requirements on this. With the rapid development of economy and technology today, traditional geometric general-purpose measuring tools are becoming less and less suitable for large-scale measurement conditions on modern construction sites, and optical measuring devices are usually more Huge, not suitable for the high efficiency require...
