This board is produced through a high-temperature autoclaving process using a slurry method, and possesses numerous superior properties and a wide range of applications. Wall repair kits are combinations of tools or equipment specifically designed to repair various wall damages (such as cracks, holes, unevenness, mold, peeling, etc.). These kits may contain multiple components to address different types of wall damage and repair needs. When encountering walls requiring repair, Eternit board and wall repair kits can be used for restoration.

[0003] Most existing Eternit board wall repair devices require manual hand-holding to fix the Eternit board, which is inconvenient when repairing walls of different heights. The stability of the Eternit board is poor when held by hand, and it will wobble during the installation process, making it impossible to ensure accurate installation. Furthermore, it is impossible to ensure that the wall surface is flat, clean, and free of oil stains and loose materials, which causes trouble for subsequent installation.

[0004] Therefore, it is necessary to propose an Eternit board wall repair device to solve the above problems. Utility Model Content

[0024] 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.

[0025] This utility model addresses the problem of manually holding and fixing Eternit boards, which is inconvenient when repairing walls of varying heights. The stability of the Eternit board is poor when held by hand, causing it to wobble during installation and making precise installation impossible. Furthermore, it cannot guarantee that the wall surface is flat, clean, and free of oil and loose materials, creating difficulties for subsequent installation. This invention provides a solution... Figures 1-3The device shown is an Eternit board wall repair device, comprising a flatbed trolley 1. A fixing rod 2 is fixedly connected to the top surface of the flatbed trolley 1 near its edge. A frame 3 is slidably mounted on the side of the fixing rod 2 near the edge of the flatbed trolley 1. The frame 3 is square in shape. A clamping plate 32 is slidably mounted on the top of the inner wall of the frame 3. A trapezoidal block 34 is slidably mounted on the bottom of the inner wall of the frame 3. A slot 33 is formed on the bottom surface of the inner wall of the frame 3, and the trapezoidal block 34 is inserted into the slot 33. The trapezoidal block 34 is a right-angled trapezoid, and its pointed end is away from the fixing rod 2. 2. This facilitates the movement of the frame 3, allowing it to be moved to the required repair height. This makes it easier to repair walls of different heights. The frame 3 can hold the Eternit board needed for the repair. After placing the Eternit board inside the frame 3, the clamping plate 32 is moved. The clamping plate 32, in conjunction with the inner wall of the frame 3, secures the Eternit board. Once secured, the Eternit board can be accurately installed onto the wall surface. During repair, the frame 3 is raised to the appropriate height, the flatbed trolley 1 is pushed to the wall, and the flatbed trolley 1 is secured. Trapezoidal block 34... The pointed end of the trapezoidal block 34 contacts the wall surface to prevent the frame 3 from moving, thus playing a positioning role and improving the stability of the frame 3. The frame 3 will not shake or move during installation, ensuring precise installation. When the trapezoidal block 34 contacts the wall surface, moving it up and down causes the pointed end of the trapezoidal block 34 to scrape the wall surface, ensuring it is flat, clean, and free of oil and loose materials, facilitating subsequent installation. During the scraping process, the trapezoidal block 34 can be used to determine if the wall is uneven. If unevenness is found, additional tools can be used to correct it. When repairing the wall, if glue needs to be applied to the wall, no other tools are needed. The trapezoidal block 34 can help smooth the glue, making subsequent installation easier. When installing the Eternit board, the trapezoidal block 34 is moved into the groove 33, and the top surface of the trapezoidal block 34 is flush with the bottom of the inner wall of the frame 3. The trapezoidal block 34 can also play a positioning role, making it easy to accurately install the Eternit board onto the wall. Loosen the clamp 32, and the worker pushes the Eternit board through the hole at the back of the frame 3. The Eternit board contacts the wall, and the worker then carries out the installation work.

[0026] It should be noted that the top surface of the flatbed trolley 1 can be used to place Eternit board for wall repair. A push handle is installed on the top surface of the flatbed trolley 1 away from the fixing rod 2. The push handle helps to move the flatbed trolley 1 to the location of use. The bottom surface of the flatbed trolley 1 is equipped with lockable casters. After moving to the location of use, the locking mechanism can be used to lock it so that subsequent repair work can be carried out.

[0027] In this invention, a square cavity 27 is provided inside the flatbed trolley 1. The bottom of the lead screw 23 passes through the top surface of the flatbed trolley 1 and extends into the interior of the flatbed trolley 1. A first gear 24 is fixedly connected to one end of the lead screw 23 extending into the interior of the flatbed trolley 1. The first gear 24 meshes with a second gear 25. A control rod 26 is fixedly sleeved on the second gear 25. The control rod 26 is rotatably connected to the top surface of the flatbed trolley 1. The first gear 24 and the second gear 25 are located inside the square cavity 27. When adjusting the height of the frame 3, the control rod 26 is rotated. The rotation of the control rod 26 drives the second gear 25 to rotate. The rotation of the second gear 25 drives the first gear 24 to rotate. The rotation of the first gear 24 drives the lead screw 23 to rotate. The rotation of the lead screw 23 drives the slider 22 to move within the slide groove 21.

[0028] It should be noted that a groove 21 is provided on the side of the fixed rod 2 near the edge of the flatbed 1. A slider 22 is slidably connected inside the groove 21. The side wall of the slider 22 is fixedly connected to the side wall of the frame 3. The slider 22 is threadedly connected to a lead screw 23. Moving the slider 22 causes it to move within the groove 21. The movement of the slider 22 drives the frame 3 to move, thus completing the adjustment of the height of the frame 3, which is convenient for installing Eternit boards of different heights.

[0029] In this utility model, the length and width of the clamping plate 32 are the same as the length and width of the top surface of the inner wall of the frame 3; the length and width of the clamping plate 32 facilitate the fixing of Eternit plates of different widths. When the trapezoidal block 34 contacts the bottom surface of the clamping plate 32, it can be moved downwards to clean and coat the installation area.

[0030] In this utility model, a through groove 37 is provided through the side wall of the frame 3. A connecting block 35 is slidably connected inside the through groove 37. One side of the connecting block 35 is fixedly connected to the side wall of the trapezoidal block 34, and a handle 36 is fixedly connected to the other side of the connecting block 35. The handle 36 is movably connected through the through groove 37. When cleaning and coating are required, the worker holds the handle 36 and moves the handle 36 up and down. The movement of the handle 36 drives the connecting block 35 and the trapezoidal block 34 to move, which is the best preliminary work for repairing the wall surface.

[0031] It should be noted that the frame 3 has an opening 31 on the side away from the through groove 37; the Eternit board is inserted into the frame 3 through the opening 31, so that when installing Eternit boards of different heights, it is not necessary to move the flatbed cart 1 frequently.

[0032] It should also be noted that there are two threaded rods 38 on the top surface of the frame 3. The threaded rods 38 pass through the top of the frame 3 and are rotatably connected to the top surface of the clamping plate 32. When it is necessary to fix the Eternit plate, rotate the threaded rods 38. The threaded rods 38 move and drive the clamping plate 32 to move. The clamping plate 32 contacts the top surface of the Eternit plate and fixes it, which facilitates subsequent installation.
