Description

Technical Field

[0001] This utility model relates to the field of flatness detection technology, specifically to an auxiliary distance measuring instrument for wall flatness. Background Technology

[0002] Wall flatness inspection is a crucial step in the construction process, directly impacting the quality of subsequent decoration work. For example, uneven walls can lead to problems such as wavy wallpaper or paint, and uneven tile installation.

[0003] Existing methods for wall flatness inspection mostly rely on straightedges. However, after the straightedge inspection is completed, the wall surface needs to be further processed. The existing inspection methods cannot accurately measure the distance between the wall surface and the straightedge, making it inconvenient to perform secondary maintenance on the wall surface. Therefore, we propose an auxiliary distance measuring instrument for wall flatness. Utility Model Content

Detailed Implementation

[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a wall flatness auxiliary distance measuring instrument, including a flatness detection mechanism 1, the flatness detection mechanism 1 being foldable, a support plate 2 fixedly installed at the bottom of the flatness detection mechanism 1, a sliding groove 3 on the flatness detection mechanism 1, a sliding plate 4 slidably connected inside the sliding groove 3, a distance measuring mechanism 5 for detecting the distance between the wall and the flatness detection mechanism 1 fixedly installed on the sliding plate 4, and locking mechanisms 6 for locking and fixing the foldable flatness detection mechanism 1 on both sides of the flatness detection mechanism 1.

[0019] The flatness detection mechanism 1 is foldable, which makes it convenient to inspect large-sized walls. The locking mechanism 6 can position the flatness detection mechanism 1 after it is folded to prevent it from being loosened again and affecting its carrying. The distance measuring mechanism 5 can detect the distance between the wall and the flatness detection mechanism 1, so as to make it easy to observe the distance of the wall that needs maintenance in time. The distance measuring mechanism 5 can move with the slide 3 and the slide plate 4, so that the distance measuring mechanism 5 can perform omnidirectional inspection along the wall.

[0020] Please see Figure 1 and Figure 2 The flatness detection mechanism 1 includes a first detection plate 7, a second detection plate 8, a rotating seat 9, and a rotating block 10. The rotating seat 9 is fixedly installed on one side of the second detection plate 8, and the rotating block 10 is fixedly connected to one side of the first detection plate 7. The rotating seat 9 and the rotating block 10 are rotatably connected.

[0021] When it is necessary to test the flatness of the wall, the rotating seat 9 and the rotating block 10 are used to drive the first detection plate 7 and the second detection plate 8 to open. The opened first detection plate 7 and the second detection plate 8 can be supported and limited by the support plate 2.

[0022] Please see Figure 1 and Figure 2 The locking mechanism 6 includes a first connecting plate 11, a first threaded sleeve 12, a second connecting plate 13, a second threaded sleeve 14, and a locking bolt 15. The first connecting plate 11 is fixedly connected to one side of the first detection plate 7, and the first threaded sleeve 12 is fixedly installed below the first connecting plate 11. The second connecting plate 13 is fixedly installed to one side of the second detection plate 8, and the second threaded sleeve 14 is fixedly installed at the bottom of the second connecting plate 13. The locking bolt 15 is threadedly connected to the inside of the second threaded sleeve 14.

[0023] After the first detection plate 7 and the second detection plate 8 are folded, the first threaded sleeve 12 and the second threaded sleeve 14 are in corresponding positions. Then, the locking bolt 15 is rotated to make the locking bolt 15 threadedly connected to the first threaded sleeve 12, thus completing the fixing of the first detection plate 7 and the second detection plate 8.

[0024] Please see Figures 1-4 The ranging mechanism 5 includes a connecting seat 16, a telescopic rod 17, a limiting groove 18, a limiting block 19, a limiting plate 20, a limiting sleeve 23, and a measuring ruler 24. The connecting seat 16 is fixedly installed on the sliding plate 4. The telescopic rod 17 is slidably connected inside the connecting seat 16. Two sets of limiting grooves 18 are provided on the connecting seat 16. A limiting block 19, inserted into the limiting groove 18, is fixedly connected to the outside of the telescopic rod 17. One end of the telescopic rod 17 is fixedly connected to the limiting plate 20. A spring 21 is fixedly connected to one side of the telescopic rod 17 and located outside the telescopic rod 17. One side of the spring 21 is fixedly connected to the connecting seat 16. One side of the connecting seat 16 is fixedly connected to the limiting sleeve 23 through two sets of support rods 22. A measuring ruler 24 is slidably connected inside the limiting sleeve 23. One side of the measuring ruler 24 is fixedly connected to the limiting plate 20. When the ball bearing 25 is located on the same vertical plane as the first detection plate 7 and the second detection plate 8, the zero mark of the measuring ruler 24 coincides with one end of the limiting sleeve 23.

[0025] When measuring the distance between the flatness detection mechanisms 1 of the wall surface, the elastic force of the spring 21 can cause the telescopic rod 17 to extend forward, which can cause the zero mark of the measuring ruler 24 to move forward. At this time, the reading of the measuring ruler 24 can be read by using the blocking of the limiting sleeve 23, so that the distance between the wall surface and the flatness detection mechanism 1 can be easily obtained. When the telescopic rod 17 moves, it can be limited by the limiting groove 18 and the limiting block 19 to prevent the telescopic rod 17 from rotating.

[0026] Please see Figure 4 The end of the telescopic rod 17 away from the limiting plate 20 is rotatably connected to a ball bearing 25. The ball bearing 25 on one side of the telescopic rod 17 facilitates the entire ranging mechanism 5 to detect along the wall surface.

[0027] In use, the flatness detection mechanism 1 is foldable, facilitating the inspection of large walls. The locking mechanism 6 positions the mechanism after folding, preventing it from unwinding and affecting portability. The distance measuring mechanism 5 detects the distance between the wall and the mechanism, allowing for timely observation of areas requiring maintenance. The distance measuring mechanism 5 moves with the slide rail 3 and slide plate 4, enabling omnidirectional inspection along the wall. When wall flatness inspection is needed, the rotating seat 9 and rotating block 10 open the first and second detection plates 7 and 8. The opened plates are supported and limited by the support plate 2. After plate 7 and the second detection plate 8 are folded, the first threaded sleeve 12 and the second threaded sleeve 14 are in corresponding positions. Then, the locking bolt 15 is rotated to make the locking bolt 15 threadedly connected to the first threaded sleeve 12, thus completing the fixation of the first detection plate 7 and the second detection plate 8. When measuring the distance between the flatness detection mechanism 1 of the wall surface, the elastic force of the spring 21 can cause the telescopic rod 17 to extend forward, which can cause the zero mark of the measuring ruler 24 to move forward. At this time, the reading of the measuring ruler 24 can be read by using the blocking of the limiting sleeve 23, so that the distance between the wall surface and the flatness detection mechanism 1 can be easily obtained. When the telescopic rod 17 moves, it can be limited by the limiting groove 18 and the limiting block 19 to prevent the telescopic rod 17 from rotating.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
