Wall flatness detection device for real estate evaluation

Abstract

The invention discloses a wall surface flatness detection device for real estate evaluation, and belongs to the field of wall surface quality detection devices, the wall surface flatness detection device comprises a supporting disc, the front end of the supporting disc is movably connected with a supporting rod, one end, far away from the supporting disc, of the supporting rod is movably connected with a measuring device, and the flatness of a wall surface can be measured through the measuring device. According to the measuring device, in the rotating process of the measuring device, when the measuring device encounters a convex position of the wall surface, a colored annular ring is left on the wall surface, when the measuring device encounters a concave position on the wall surface, no mark is left on the wall surface, and when the height of the convex position on the wall surface is large, the color of liquid at the end becomes light after colored liquid and transparent water are mixed; in other words, when the convexity of the wall surface is higher, the colors of the colored annular rings left on the wall surface are lighter, in this way, a plurality of colored annular rings can be left on the wall surface along with rotation of the measuring device, and whether the wall surface is flat or not can be judged according to the color depth of the colored annular rings.

Description

technical field [0001] The invention relates to the field of wall quality detection devices, in particular to a wall surface flatness detection device for real estate evaluation. Background technique [0002] In the process of house evaluation, the appraiser needs to measure the quality of the house in order to evaluate the price in line with the actual value of the house. Generally, the quality of the house is tested by some testing instruments. When testing the quality of the house, it is often necessary to Check the flatness of the wall. [0003] Most of the traditional inspection methods are to put the spirit level on the wall to judge whether the wall is flat or not according to the position of the bubbles on the spirit level. In this way, the inspection of the wall not only has a small range but also has a large error. [0004] The Chinese patent discloses a wall flatness detection device for real estate evaluation (authorized announcement number CN216205983U). The pa...

[0004] A Chinese patent discloses a wall flatness detection device for real estate evaluation (authorized notification number CN216205983U). This patent, through the mutual cooperation of the first screw rod and the second screw rod, improves the accuracy of the wall when detecting the wall. The stability of the detection wheel and the infrared rangefinder is used to improve the accuracy of the measurement. However, this device can only check whether the wall is flat or not, and cannot allow the inspector to clearly observe the location of the uneven area on the wall.
