Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wall surface inspection technology, and in particular relates to a tool for inspecting the flatness of green building decoration walls. Background Technology
[0002] Wall flatness inspection is a crucial step in decoration and construction projects. Ensuring wall flatness can improve the overall visual effect and facilitate the smooth progress of other construction stages.
[0003] In existing technology, the detection block is abutted against the wall by a spring, and then the detection block is moved horizontally. A water-writing pen set on the detection block can draw lines on the water-writing cloth. The flatness of the wall surface in the detection area can be judged by whether the lines are curved.
[0004] When using a water-writing pen and a water-writing cloth to mark the flatness of a wall, in order to ensure the integrity of each writing, the water-writing cloth needs to be fixed above the water-writing pen. When it is necessary to test the flatness of other areas, a new writing cloth needs to be replaced, which not only wastes resources but also reduces work efficiency.
[0005] To address these issues, we provide a tool for testing the flatness of walls in green building renovations. Utility Model Content
[0006] The purpose of this utility model is to provide a tool for detecting the flatness of walls in green building decoration. A second motor controls a winding roller to wind the paper. When the electromagnet is de-energized, the limit on the writing paper is released, allowing it to be wound up. When energized, the writing paper is clamped to ensure that it remains stable during writing. The writing paper can be quickly replaced during use, saving on the amount of writing paper used and increasing work efficiency.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1
[0030] Please see Figure 1-6 This utility model is a tool for testing the flatness of green building decoration walls, including a base frame 1 and two support plates 2 symmetrically arranged on the surface of the base frame 1; a replacement component 3 is provided on the base frame 1, the replacement component 3 includes a replacement frame 4, two take-up rollers 5 are rotatably arranged on the replacement frame 4, two electromagnets 6 are symmetrically fixedly connected inside the replacement frame 4, two iron blocks 7 corresponding to the electromagnets 6 are symmetrically slidably arranged on the replacement frame 4, sliders 8 are fixedly connected to the sides of the two iron blocks 7, ear plates 9 are fixedly connected to the two opposite sides of the replacement frame 4, slide rods 10 are fixedly connected to the two ear plates 9, the two sliders 8 are slidably connected to the corresponding slide rods 10 respectively, and a return spring 11 is fixedly connected between the two sliders 8 and the corresponding ear plates 9, and a writing paper 12 is driven between the two take-up rollers 5.
[0031] The operation process of this embodiment is as follows: During use, the replacement frame 4 is moved to the area to be tested. After the base frame 1 is fixed in an appropriate position, after testing a section of the wall, the replacement frame 4 is moved to another area to be tested. After the electromagnet 6 is de-energized, the reset spring 11 is reset. The writing paper 12, which is no longer limited by the electromagnet 6 and the iron block 7, can be moved. By rotating a winding roller 5, the writing paper 12 is wound up. Similarly, by energizing the electromagnet 6, the writing paper 12 can be clamped, and the flatness of the wall in the new area can be tested again. During use, the writing paper 12 can be moved during the testing of different areas by winding up the writing paper 12 and turning the electromagnet 6 on and off. This reduces the use of the writing paper 12 and improves work efficiency. Specific Implementation Example 2
[0033] Please see Figure 4-5 Based on the first specific embodiment, a movable component 13 is slidably fitted on the base frame 1. The movable component 13 includes a lifting plate 14. A U-shaped plate 15 is fixedly connected to the side of the lifting plate 14. A first lead screw 16 is rotatably connected through the U-shaped plate 15. A round rod 17 is fixedly connected to the U-shaped plate 15. A first motor 18 is fixedly connected to the side of the U-shaped plate 15. The output end of the first motor 18 is fixedly connected to the first lead screw 16. A movable sleeve 19 is threadedly connected to the first lead screw 16. The movable sleeve 19 is slidably connected to the round rod 17. A cavity 20 is opened inside the movable sleeve 19. A square rod 21 is slidably arranged inside the cavity 20. A baffle 22 is fixedly connected to one end of the square rod 21. A tension spring 23 is fixedly connected between the baffle 22 and the movable sleeve 19. A connecting block 24 is fixedly connected to the other end of the square rod 21. A roller 25 is rotatably connected inside the connecting block 24. A writing pen 26 is fixedly connected to the side of the connecting block 24.
[0034] The operation process of this embodiment is as follows: During the flatness detection of the wall surface, the lifting plate 14 is moved to an appropriate height, and the first lead screw 16 is rotated by the first motor 18, which allows the moving sleeve 19 to slide on the U-shaped plate 15. During the sliding, the U-shaped plate 15 is affected by the elastic force of the tension spring 23, and the roller 25 is always in close contact with the wall surface. When the wall surface in the detection area is uneven, the mark drawn by the writing pen 26 on the writing paper 12 changes from a straight line to a curve. The flatness of the wall surface in the detection area can be detected by the writing mark on the writing paper 12, which enables the flatness detection of the wall surface quickly.

[0037] The operation process of this embodiment is as follows: the second motor 33 drives a winding roller 5 to rotate, which can wind up the writing paper 12 and move the writing paper 12. By rotating the handwheel 29, the handwheel 29 drives the second lead screw 28 to rotate. The rotation of the second lead screw 28 drives the sliding sleeve 32 to move. The sliding sleeve 32 drives the lifting plate 14 to move, which can adjust the detection height and further improve the applicability of the device.
