In order to increase the efficiency and simplify the operation, various novel guiding rules, such as CN106767742A, are presented, the automation degree of detection is improved, but compared with the traditional guiding rule form, the use flexibility and the operation convenience are slightly insufficient; for example, CN107543536a, the working surface of the wall is a plane, so that the flatness data detection speed is improved by the laser range finder, but the observation is inconvenient in a one-by-one display mode, especially the edge of the laser range finder is close to the wall surface, and the detection accuracy is affected; in addition, as for the technical scheme of CN208765698U, CN208736325U, CN208736390U, CN108534736A series applied by Jiangsu Nantong two-construction group in a mode of detecting flatness and verticality based on laser ranging, detecting verticality by an electronic measurement module of verticality and detecting flatness and verticality by a mechanical measurement mechanism (also called a verticality correction device and a pointer type verticality calibrator), the wall leaning part is a leaning foot, a laser probe is arranged in a mounting hole in the mode of detecting flatness based on laser ranging, the problem of influence on detection accuracy due to the fact that the wall leaning is close to a wall surface also exists, the implementation and principle of the verticality detection by the electronic measurement module are described to be fuzzy, at least the implementation of the detection by the electronic measurement module of verticality is not combined, the detection is judged according to the practical experience of the applicant, and the declared verticality electronic measurement is based on an inclination sensor and an acceleration sensor, so that the manufacturing cost is relatively high; after the mechanical measuring mechanism is attached to the wall surface through the guiding ruler (leaning leg), the verticality is detected by means of the pointer reading of the mechanical measuring mechanism, but how to detect the flatness is unclear, various detection modes are mixed, and the mechanical measuring mechanism is complex and inconvenient to operate.

In order to solve the technical problems, the invention adopts the following technical scheme:
the wall surface verticality flatness measuring equipment comprises a guiding rule main body, wherein the guiding rule main body is of a strip-shaped structure with a rectangular square frame in section, and the guiding rule main body consists of a wall-leaning working panel, a lower bottom plate opposite to the wall-leaning working panel, two side plates for connecting the wall-leaning working panel and the lower bottom plate and two end plates respectively arranged at two ends; the guiding ruler body is provided with a data display screen, a control analysis module, a detection switching button, a power supply module for supplying power, a switch button for controlling the power supply module and at least three ranging modules;
all the ranging modules are arranged at intervals along the length direction of the guiding rule main body, each ranging module comprises a through hole formed in a wall-leaning working panel and a laser range finder arranged on the inner side surface of the lower bottom plate, and the emitting port of each laser range finder is opposite to the through hole so that laser emitted by the laser range finder can pass through the through hole and finish ranging; the vertical distance from the emitting opening of the laser range finder to the outer side surface of the wall-leaning working panel is not less than five centimeters;
the outer side surface of the side plate is provided with a pointer type verticality calibrator for calibrating the verticality of the guiding rule main body before measuring the verticality; the switch button, the detection switch button and the data display screen are embedded on the side plate so as to be convenient to operate and observe;

Pressing the switch button 134 turns on the present measuring apparatus, i.e., starts power supply, and long-pressing the detection switch button 132 switches the detection of verticality or flatness. When the flatness is selected to be detected, the wall-leaning working panel 11 is attached to the wall surface, the detection switching button 132 is pressed for a short time to start detection, the laser rangefinder 125 works to obtain range data and transmits the range data to the control analysis module 121, and the control analysis module 121 obtains the flatness detection result after 1-2 seconds to output and display the flatness detection result on the data display screen 131 so that a user can observe and acquire the detection result.

Example two

The through hole 111 is formed at the trough position of the wall-contacting working panel 11, so that the problem of unreliable line contact position caused by the crest position can be avoided.
In implementation, the detection of verticality can also be performed by directly pasting the wall-leaning working panel 11 on the measured wall surface, and directly reading and recording after the pointer of the pointer type verticality calibrator 133 (similar to the mechanical measuring mechanism in CN 108534736A) is stabilized, which belongs to the traditional mode, has low precision and reading error and can be used as a standby means.
