Description

Technical Field

[0001] The present application relates to the technical field of flatness detection devices, and more specifically, to a flatness detection device for building walls. Background Art

[0002] During the interior decoration of buildings, tiles are pasted on the walls of kitchens and bathrooms. The flatness of the tile-pasting surface reflects the quality of the tile-pasting process and is also one of the important indicators for demonstrating the beauty of decoration. Currently, the effective detection method is to manually measure using a liquid-level spirit level board, and the measurement accuracy is relatively low. The building flatness detection device proposed in the existing publication number CN210321700U has the advantage of being able to protect the test unit and reduce the occurrence of damage to the test unit. In view of the above-mentioned related technologies, the utility model inventors believe that there are still the following defects: In the flatness detection device in the comparative literature, although multiple detection units are set and arranged in a rotating arc shape for detection, when testing a tile wall, it is easy to have horizontal or vertical detection omission phenomena. During detection, the detection device cannot achieve stable limiting treatment with the tile wall, and the detection is prone to errors, resulting in inaccurate results and inconvenient height adjustment. In view of this, we propose a flatness detection device for building walls. Summary of the Utility Model

During detection, the detection device cannot achieve stable limiting treatment with the tile wall, and the detection is prone to errors, resulting in inaccurate results and inconvenient height adjustment. It realizes the technical effect that the flatness measuring instrument is installed on the convex guide rail, and the installation height and angle on the moving frame can be adjusted, which is convenient to use, easy to move, and has strong practicability. By adjusting the two calibration screws to abut against the tile wall, using the scales of the two spirit level boards, the parallelism between the convex guide rail and the tile wall is calibrated, and the digital dial indicator is zeroed. And using the two positioners to limit the overall device with the tile wall. The digital dial indicator slides along the convex guide rail through the sliding seat. When there are concave and convex surfaces on the wall, the guide wheel forces the measuring rod to displace into the sliding seat, causing the digital display number of the digital dial indicator to change, and the flatness of the tile wall can be quickly detected.

During use, for the calibration assemblies 4 at both ends of the convex guide rail 2, by rotating and adjusting the calibration screw 41, the calibration screw 41 is made to abut against the tile wall. By reading the scales of the two ruler plates 44, the parallelism between the convex guide rail 2 and the tile wall is calibrated, and the digital dial indicator 52 is zeroed. Then, by using the positioner 3, that is, rotating the positioning screw 31, the suction cup 33 is made to adsorb the tile surface, so that the overall device is limited to the tile wall. Then, the zeroed digital dial indicator 52 slides horizontally along the convex guide rail 2 through the slide base 51, and the guide wheel 54 connected to the measuring rod 53 displaces along the tile wall. When there are concave and convex surfaces on the tile wall, the guide wheel 54 forces the measuring rod 53 to displace into the slide base 51, causing the digital display number of the digital dial indicator 52 to change.

After the convex guide rail 2 is horizontally adjusted with the ceramic tile wall surface, the sliding seat 51 slides along the convex guide rail 2. When there are convex and concave surfaces on the surface of the ceramic tile, the guide wheel 54 forces the measuring rod 53 to displace into the sliding seat 51, causing the digital display number of the digital dial indicator 52 to change, and then the flatness of the ceramic tile wall surface can be quickly detected.

[0028] Working principle: When pasting tiles on the building wall for decoration, it is necessary to detect and process the surface flatness of the tile wall. Move the mobile frame 1 to the vicinity of the tile wall, and the slider 14 slides vertically along the vertical rod 13 to adjust the installation height of the flatness measuring instrument 5. During use, for the calibration components 4 at both ends of the convex guide rail 2, by rotating and adjusting the calibration screw 41, the calibration screw 41 is made to contact the tile wall. By reading the scales of the two scale plates 44, the parallelism between the convex guide rail 2 and the tile wall is calibrated, and the digital dial indicator 52 is processed for zeroing. Then, use the locator 3, that is, rotate the positioning screw 31 to make the suction cup 33 adsorb the tile surface, so that the overall device is limited to the tile wall. Then, the digital dial indicator 52 after zeroing is horizontally slid along the convex guide rail 2 through the sliding seat 51, and the guide wheel 54 connected to the measuring rod 53 displaces along the tile wall. When there are concave and convex surfaces on the tile wall, the guide wheel 54 forces the measuring rod 53 to displace into the sliding seat 51, causing the digital display number of the digital dial indicator 52 to change.
