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

A kind of wall flatness detection device involves the field of wall flatness detection technology, which is used to achieve precise detection of wall flatness, and the detection device is convenient for carrying and flexible structure.A kind of wall flat degree detection device provided by the present invention, press the detection device on the wall through three support legs, rotate the first and second cylinders on the base, and there is a spring on the second turret., Steel ball and force sensor, squeeze between steel balls and to be measured to measure the wall, and pass the force to the force sensor through the spring. Through the size and value distribution of the perception of the force sensor, you can clearly understand the wall surface of the wall surface.Flatness.And adjust the rotation radius of spring and steel balls to get more sampling.The support legs can be retracted and can be folded relative to the base, which is easy to carry.

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 ...
