DETAILED DESCRIPTION

[0019] Clearly, the embodiments described are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work shall fall within the protection scope of the present application.

[0020] Please refer to Figures 1-8 An embodiment of the present application is: a measuring device for building decoration engineering, comprising a positioning box 1, a semicircular plate 2 is fixed on the back of the positioning box 1 and is rotationally connected at the penetrating position, a rotating block 3 is penetrated in the semicircular plate 2, an connecting rod 4 is fixed on the outer wall of the rotating block 3, the connecting rod 4 is slidably connected at the penetrating position of the semicircular plate 2, a long plate 5 is fixed on the end of the connecting rod 4 away from the rotating block 3, the side wall of the long plate 5 close to the connecting rod 4 is slidably connected with the outer wall of the semicircular plate 2, and a visual device for measuring the ground levelness and the wall perpendicularity is arranged in the long plate 5.

[0021] The visualization device comprises an L-shaped rod 61, a spherical connecting block 62, a swing connecting block 63, a long rod 64, a counterweight block 65, a sliding block 66, a pressing plate 67, a first spring 68, a first visible block 69, a second spring 610 and a second visible block 611. The L-shaped rod 61 is fixedly connected to the upper end of the side wall of the long plate 5. The spherical connecting block 62 is fixedly connected to the end of the L-shaped rod 61 away from the long plate 5. The inner wall of the swing connecting block 63 is attached to the outer wall of the spherical connecting block 62. The long rod 64 is fixedly connected to the outer wall of the swing connecting block 63. The counterweight block 65 is fixedly connected to the end of the long rod 64 away from the swing connecting block 63. When measuring the levelness of the ground, the positioning box 1 is placed on the ground and placed in multiple directions. Since the counterweight block 65 is always affected by the vertical downward gravity, the long rod 64 is always in a vertical state. When the ground is not in a horizontal state and one side of the semicircular plate 2 is lower, the counterweight block 65 is close to the long plate 5, driving the long rod 64 to be close to the long plate 5. The sliding block 66 penetrates through the long plate 5 and is slidingly connected at the penetration position. The long rod 64 drives the sliding block 66 to slide to the back of the long plate 5. The pressing plate 67 is fixedly connected to the side wall of the sliding block 66. The pressing plate 67 penetrates through the long plate 5 and is slidingly connected at the penetration position. The sliding block 66 drives the pressing plate 67 to slide to the back of the long plate 5. One end of the first spring 68 is fixedly connected to the back of the inner wall of the long plate 5. The first visible block 69 is slidingly connected to the back of the inner wall of the long plate 5. The other end of the first spring 68 is fixedly connected to the side wall of the first visible block 69. The pressing plate 67 drives the first visible block 69 to slide away from the sliding block 66, simultaneously stretching the first spring 68. Each group of sliding blocks 66 slides different distances according to the inclination of the long rod 64 affected by the counterweight block 65, so that the part of the first visible block 69 sliding out of the long plate 5 forms an inclined line. One end of the second spring 610 is fixedly connected to the front of the inner wall of the long plate 5. The second visible block 611 is slidingly connected to the front of the inner wall of the long plate 5. The other end of the second spring 610 is fixedly connected to the side wall of the second visible block 611. When measuring the perpendicularity of the wall surface, the left side of the positioning box 1 is attached to the wall surface. The long plate 5 is rotated to change from a vertical state to a horizontal state. The positioning box 1 is pushed to the corner of the wall. When the wall surface is not in a perpendicular state, the sliding block 66 first contacting the wall surface is pushed by the wall surface to slide to the front of the long plate 5. The sliding block 66 drives the pressing plate 67 to slide to the front of the long plate 5. The pressing plate 67 drives the second visible block 611 to slide away from the sliding block 66, simultaneously stretching the second spring 610. Each group of sliding blocks 66 slides different distances according to the sequence of contacting the wall surface, so that the part of the second visible block 611 sliding out of the long plate 5 forms an inclined line.By converting the angle between the vertical rod 64 and the long plate 5 into the sliding distance of the first visible block 69, the angle between the ground and the horizontal line becomes easier to observe with the naked eye, and the influence of the environment on the instrument is avoided. This solves the problem that bubble levels are easily affected by changes in bubble size and temperature, leading to errors. In conjunction with the second spring 610 and the second visible block 611, when the two walls are not perpendicular, the angle between the two walls is converted into the sliding distance of the second visible block 611, making it easier for the angle between the two walls to be observed by the naked eye. This also reduces the work steps of the measuring personnel and solves the problem that existing physical measuring instruments are relatively troublesome when detecting verticality.

[0022] In this embodiment, during operation: When measuring the levelness of the ground, the positioning box 1 is placed on the ground and its orientation is changed multiple times. Because the counterweight 65 is constantly subjected to a downward vertical force, the long rod 64 remains vertical. When the ground is not level and one side of the semicircular plate 2 is lower, the counterweight 65 approaches the long plate 5. The long rod 64, under the influence of the counterweight 65's gravity, causes the swing connecting block 63 to rotate against the outer wall of the spherical connecting block 62. When the counterweight 65 causes the long rod 64 to approach the long plate 5, the long rod 64 pushes the sliding block 66 to slide towards the back of the long plate 5. As the sliding block 66 slides, it also causes the pressing plate 67 to slide towards the back of the long plate 5. When the pressing plate 67 slides to the first visible block 69, the side of the pressing plate 67 slides against the inclined surface of the first visible block 69, pushing the first visible block 69 away from the sliding block 66. Simultaneously, the first spring 68 is stretched. 9. Multiple sets are provided. When the long rod 64 pushes the sliding block 66 to slide, each set of sliding blocks 66 slides at different distances depending on the influence of the counterweight 65 on the long rod 64, so that the part of the first visible block 69 that slides out of the long plate 5 forms an oblique line. When measuring the verticality of the wall, the left side of the positioning box 1 is attached to the wall, the long plate 5 is rotated to change the long plate 5 from a vertical state to a horizontal state, and the positioning box 1 is pushed towards the corner of the wall. When the wall is not in a vertical state, the sliding block 66 that first contacts the wall is pushed by the wall and slides towards the front of the long plate 5. When the sliding block 66 slides, it drives the pressing plate 67 to slide towards the front of the long plate 5. When the pressing plate 67 slides to the second visible block 611, it pushes the second visible block 611 to slide away from the sliding block 66, and at the same time stretches the second spring 610. Each set of sliding blocks 66 slides at different distances according to the order of contact with the wall, so that the part of the second visible block 611 that slides out of the long plate 5 forms an oblique line.
