Embodiment Construction

[0025] Such as Figure 1 to Figure 11 As shown, the present invention includes a base 1, a first drum 2, a second drum 3, a movable block 4, a fixed cross bar 41, a movable cross bar 42, a vertical rod 43, a fixed cylinder 44, a spring 45, and a steel ball 46. , the first leg 5, the second leg 6, the third leg 7, the top wire and the rotating shaft 9, the present invention will be described below in conjunction with the accompanying drawings.

[0026] Such as figure 1 As shown, the base 1 is a circular metal piece, and three U-shaped notches 11 are provided at the edge of the base. The notches pass through the cylindrical outer wall of the base, and the notches can be obtained by milling. The three notches are arranged at equal intervals along the same circumference, and a circular hole is provided in the center of the base, and a horizontally placed bearing 13 is fixedly installed in the circular hole, and a vertically placed first drum 2 is fixedly installed in the bearing,...

Abstract

The invention discloses a wall flatness detection device and relates to the technical field of wall flatness detection; the device is used for detecting the wall flatness accurately and is convenient to carry and flexible in structure. A device body is pressed onto a wall through three support legs, a first and second rotary barrels are rotationally mounted on a base, a spring, a steel ball and a force sensor are arranged on the second rotary barrel, the steel ball and the wall to be detected is pressed mutually, the stress is transmitted to the force sensor through the spring, and the flatness of the wall can be known clearly by the force sensor sensing the force magnitude and value distribution. More samples can be obtained by adjusting the rotating radius of the spring and steel ball. The supporting legs are telescopic and can be folded corresponded to the base, and carrying is facilitated.

Description

technical field [0001] The invention relates to the technical field of wall surface flatness detection, in particular to a device for detecting wall surface flatness by using the principle of determining a plane with three points. Background technique [0002] In the construction industry, after the wall construction is completed, the flatness inspection is required to determine whether the construction quality meets the standards. Existing patents include a device for detecting wall flatness using lasers, such as the laser detector for wall flatness published in Chinese patent 2012200536706, which utilizes the principle of laser ranging. The wall or ground flatness detection device disclosed in Chinese patent 2014202204422 is also a device that uses the principle of laser ranging to detect the wall flatness, but its structure is complicated and the manufacturing cost is high. Therefore, be badly in need of a kind of simple in structure, easy to carry wall surface flatness ...
