[0022] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] A wall flatness testing device includes a horizontal moving rail frame 1 and a mounting box 2 set on the horizontal moving rail frame 1. Three sets of testing components 21 are equidistantly arranged on one side of the mounting box 2. A cylinder 3 is provided at the lower end of the horizontal moving rail frame 1. The base of the cylinder 3 is mounted on a support platform 41.

[0024] A calibration mechanism 4 is provided on the support platform 41;

[0025] The calibration mechanism 4 includes a limiting rail plate 42 relatively distributed on the support platform 41 and a positioning slide plate 43 for sliding connection with the limiting rail plate 42. A calibration plate 45 is fixedly connected between the two positioning slide plates 43. A level bubble 46 for calibration is provided on the calibration plate 45. A connecting plate 48 is fixedly connected to one end of the two positioning slide plates 43 away from the calibration plate 45. A handle 483 is provided at the upper end of the connecting plate 48.

[0026] This invention provides a wall flatness testing device. Before testing, the connecting plate is pushed by the handle to bring the calibration plate close to the wall, ensuring the horizontal moving rail is parallel to the wall. Simultaneously, the spirit level is observed to avoid testing on uneven surfaces. During testing, the head of the testing component lightly touches the wall surface. This avoids errors in flatness testing results caused by the device's tilt, thus improving the accuracy of the test results.

[0027] Furthermore, as a preferred embodiment of this solution and not a limitation, the limiting rail plate 42 is provided with a positioning groove 44 for the movement of the connecting plate 48, and the connecting plate 48 is provided with positioning bolts 482 corresponding to the positioning groove 44. More specifically, after the positioning slide plate 43 is attached to and in contact with the wall using the calibration plate 45 and the bubble level 46, the positioning slide plate 43 can be fixed by inserting and tightening the positioning bolts 482 into the positioning groove 44 to ensure that the positioning slide plate 43 remains in position and to prevent the calibration plate 45 from moving inward to the inside of the limiting rail plate 42 when the support platform 41 is moved subsequently.

[0028] Furthermore, as a preferred embodiment of this solution and not a limitation, the connecting plate 48 is provided with opposing slots, and a pulley 481 is rotatably connected within the slot. By providing the pulley 481 on the connecting plate 48, it is convenient for workers to push the connecting plate 48 to move synchronously with the relatively distributed positioning slide plates 43 and the calibration plate 45 mounted on the positioning slide plates 43.

[0029] Furthermore, as a preferred embodiment of this solution and not a limitation, a plurality of casters 47 are evenly distributed at the lower end of the support platform 41. It should be noted that by providing casters 47 under the support platform 41, the use of the entire device becomes more flexible.

[0030] Furthermore, as a preferred embodiment of this solution and not a limitation, a limiting groove is provided on the support platform 41, and a protrusion 52 for sliding connection with the limiting groove is fixedly connected to the lower end of the cylinder 3. A servo motor 5 is installed at the lower end of the support platform 41, and a lead screw 51 is threaded into the protrusion 52. One end of the lead screw 51 is fixedly connected to the output end of the servo motor 5. It is worth mentioning that by installing the servo motor 5 at the lower end of the support platform 41, after the calibration plate 45 is in close contact with the wall, the servo motor 5 is started to rotate the lead screw 51 to drive the cylinder 3 to bend the mounting box 2 on the transverse moving rail 1 and move it closer to the wall. After the head of the detection component 21 on the mounting box 2 lightly touches the wall, detection can be performed. The mounting box 2 and the detection component 21 are existing devices for wall plane detection.

[0031] Furthermore, as a preferred embodiment of this solution and not a limitation, the transverse moving rail frame 1 is equipped with a transverse moving motor 7 and a threaded rod 71 located on the output end of the transverse moving motor 7. The mounting box 2 is threadedly engaged with the threaded rod 71 and slidably engaged with the transverse moving rail frame 1. The detection component includes guide wheels that roll on the wall surface. When encountering a protruding wall surface, the guide wheels move to the left, and the sliding rod also moves to the left. When encountering a recessed wall surface, the guide wheels are reset by the elastic action of a spring, thereby driving the sliding rod to move. The left and right movement of the sliding rod is detected by an infrared sensor, and the detection result of the infrared sensor is displayed on the control panel to determine the flatness of the wall surface.

[0032] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a mounting bracket 6 for fixing the cylinder 3. The mounting bracket 6 includes a base plate 61 and a top plate 62, and connecting rods 63 connecting the four corners of the base plate 61 and the top plate 62. The cylinder 3 is installed between the base plate 61 and the top plate 62. This facilitates the support of the cylinder and ensures that the cylinder is vertical.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, the mounting frame 6 is provided with two telescopic rods 8, which are respectively located on both sides of the cylinder 3 and connected to the transverse moving rail frame 1. The telescopic rods support the lifting and lowering of the transverse moving rail while preventing the transverse moving rail frame from rotating or deviating.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the telescopic rod 8 includes a main body 81 and an extension 82. The main body 81 is mounted on the base plate 61 and passes through the top plate 62, and the extension 82 is connected to the transverse moving rail frame 1.

[0035] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
