[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model provides Figure 1-Figure 2 A construction project quality flatness detection tool is shown, which specifically includes a back plate 1, on which a controller 2 is installed, and the controller 2 is preferably installed on the upper end surface of the back plate 1, and a handle 6 is installed on the back of the back plate 1. At least two handles 6 are installed, and the handles 6 are used for users to hold, and when two handles 6 are provided, the two handles 6 are symmetrically arranged, and the front side of the back plate 1 is concave inward along the length direction to form a mounting groove 8, and at least one end of the mounting groove 8 is open, and a plurality of mounting blocks 11 are arranged in the mounting groove 8, each mounting block 11 is detachably connected to the back plate 1 by a threaded connection, and each mounting block 11 is provided with a moving wheel 9, and an elastic connecting member 3 is installed between the moving wheel 9 and the mounting block 11.

[0029] See also Figure 3 As shown, the upper and lower ends of the interior of the mounting groove 8 are provided with slide grooves 10, and the upper and lower ends of the mounting block 11 are connected with slide bars 12, which slide in the slide grooves 10. The slide bars 12 slide in the slide grooves 10 to facilitate stable adjustment of the position of the mounting block 11.

[0030] Among them, see Figure 4 and Figure 5 As shown, the elastic connecting member 3 includes a first connecting column 31 and a second connecting column 32. One end of the first connecting column 31 is fixed to the mounting block 11, and a groove 33 is axially provided in the first connecting column 31. A pressure sensor 34 is installed inside the groove 33. The pressure sensor 34 is electrically connected to the controller 2. A spring 35 is connected between the pressure sensor 34 and the first connecting column 31. When the spring 35 is in a natural state, the moving wheel 9 protrudes from the front of the back plate 1, and the outer ends of the moving wheel 9 are on the same plane.

[0031] The diameter of the second connecting column 32 does not exceed the inner diameter of the groove 33 , and one end of the second connecting column 32 away from the spring 35 is connected to the moving wheel 9 .

[0032] Through the above technical solution:

[0033] During specific use, the staff can use the handle 6 to hold the backboard 1, so that the front side of the backboard 1 is parallel to the wall to be measured, and the moving wheel 9 is close to the wall. Then the staff can push the backboard 1 toward the wall and push the moving wheel 9 to roll. According to the pressure generated by the compression of the spring 35 in the groove 33 and the squeezing of the pressure sensor 34, the flatness of the wall can be timely known through the controller 2.

[0034] Specifically, multiple pressure sensors 34 can be numbered in sequence and electrically connected to the controller 2. When a certain part of the wall is recessed, when the moving wheel 9 passes through the recessed area, the pressure fed back by the pressure sensor 34 corresponding to the moving wheel 9 is smaller than that in other areas; when a certain part of the wall is protruding, when the moving wheel 9 passes through the protruding area, the pressure fed back by the pressure sensor 34 corresponding to the moving wheel 9 is larger than that in other areas; if the difference in the pressure values ​​fed back by each pressure sensor 34 is within an appropriate range, it indicates that the wall is flat.

[0035] See also Figure 1 and Figure 4 As shown, the threaded connector includes:

[0036] A plurality of threaded through holes 4, which are equidistant and opened along the length direction on the back of the back plate 1, and the threaded through holes 4 are connected with the groove 33;

Secondly, the number of the elastic connectors 3 and the moving wheel 9 on the back plate 1 can be increased or decreased or the position can be changed as needed, which is more flexible.

[0040] When changing the position of the elastic connector 3 and the moving wheel 9, the corresponding bolt 5 can be loosened first to disengage the end of the bolt 5 from the threaded groove 7, and then the moving wheel 9 can be moved. The sliding bar 12 in the sliding groove 10 can be used to stably move the mounting block 11 along the length direction. After moving into place, the bolt 5 can be screwed on to limit the position.

[0041] When it is necessary to increase or decrease the elastic connecting member 3 and the moving wheel 9 , the mounting block 11 can be added or removed from the open end of the mounting groove 8 .

[0042] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
