[0001] This utility model relates to the field of building engineering technology, specifically a wall leveling device for building engineering technology. Background Technology

[0002] In construction engineering, plastering is a construction process in which a thin layer of cement mortar is applied to the surface of a wall to smooth and flatten it. This process protects the wall from external wear and tear, while also improving its waterproof and thermal insulation properties.

[0003] Application No. 202221601532.7 discloses a wall leveling device for building engineering technology. It uses a dual-axis motor to drive a threaded rod to rotate. The threaded rod moves a threaded cylinder through the principle of thread movement. The threaded cylinder pushes a connecting plate, and the connecting plate pulls a second scraper, so that the second scraper slides in the groove of the first scraper. This allows the size of the scraper to be adjusted according to the size of the wall, thereby improving the efficiency of wall leveling.

[0004] The scraper structure of the above application is relatively complex, requiring the cooperation of a threaded rod and a dual-axis motor. In addition, the cost is high, and the surfaces of the second scraper and the first scraper are not flush, which can easily lead to uneven wall surfaces. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wall leveling device for building engineering, comprising a scraper and an extension plate, wherein a mounting bracket is installed on one side of both the scraper and the extension plate, and a positioning component is installed on the side of the extension plate away from the mounting bracket. A threaded rod is threadedly connected to the inside of the mounting bracket, and a first threaded hole and a second threaded hole for threaded connection with the threaded rod are respectively opened on the adjacent sides of the positioning component. A positioning sleeve is installed at the bottom of the scraper, and a support shaft is inserted into the inside of the positioning sleeve. A bracket is rotatably connected to the outside of the support shaft, and a telescopic rod is installed at the bottom of the bracket.

[0007] Preferably, the surfaces of both the scraper and the extension plate are provided with a lotus leaf-like hydrophobic coating.

[0008] Preferably, an adjuster is installed on one side of the bracket, and the adjuster has a worm gear and a worm inside, which mesh with each other. A throttle handle is rotatably connected to the bottom of the adjuster, and the worm gear and the worm are fixedly connected to the support shaft and the throttle handle, respectively.

[0009] Preferably, a sealing ring is installed inside the positioning sleeve, and the sealing ring is in contact with the surface of the support shaft.

[0010] Preferably, the telescopic rod includes a first rod body, a second rod body is slidably connected inside the first rod body, a bolt is threadedly connected to one side of the first rod body, and one end of the bolt extends into the first rod body.

[0011] Preferably, the scraper is provided with a handle on the side adjacent to the mounting bracket.

[0012] This utility model provides a wall leveling device for building engineering technology, which has the following beneficial effects:

[0013] 1. This wall leveling device for building engineering uses mounting brackets and positioning components installed on the scraper and extension plate respectively. With the threaded rod at one end of the mounting bracket connected to the first and second threaded holes on the positioning component respectively, the scraper can be fixed to the extension plate. The number of extension plates can be increased or decreased, which is beneficial to adjust the overall length of the scraper. The structure is simple and the cost is low. The extension plate keeps the scraper flush, ensuring the flatness of the wall surface. Moreover, the extension plate can be fixed perpendicularly to the scraper, which is convenient for leveling the angle between adjacent walls.

[0014] 2. The wall shaving device used in this construction engineering technology uses a lotus leaf-like hydrophobic coating on the surface of the scraper and extension plate to reduce the adhesion of cement and gypsum to the surface, so that residual materials can be scraped off easily and are easy to clean. In addition, a detachable telescopic rod is installed at the bottom of the scraper, which facilitates operation on high walls. The angle of the scraper can be easily adjusted by the worm gear and worm in the adjuster. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 5This utility model provides a technical solution: a wall leveling device for building engineering, including a scraper 1 and an extension plate 2. A mounting bracket 3 is installed on one side of both the scraper 1 and the extension plate 2. A positioning element 4 is installed on the side of the extension plate 2 away from the mounting bracket 3. A threaded rod 5 is threadedly connected internally to the mounting bracket 3. The positioning element 4 has a first threaded hole 6 and a second threaded hole 7 on adjacent sides, respectively, for threaded connection with the threaded rod 5. By rotating the threaded rod 5, one end of the threaded rod 5 can be inserted into either the first threaded hole 6 or the second threaded hole 7 to fix the extension plate 2. This increases the leveling range of the scraper 1 and allows for vertical... The extension plate 2 is fixed to facilitate scraping the angle between adjacent walls. A handle 18 is installed on the side of the scraper 1 adjacent to the mounting bracket 3 for easy handling. Both the scraper 1 and the extension plate 2 have a lotus leaf-like hydrophobic coating 16, which helps reduce the adhesion of cement and plaster to their surfaces, allowing residual materials to be scraped off easily for cleaning. A positioning sleeve 8 is installed at the bottom of the scraper 1, and a support shaft 9 is inserted inside the positioning sleeve 8. A sealing ring 17 is installed inside the positioning sleeve 8, and the sealing ring 17 fits against the surface of the support shaft 9, increasing friction and preventing the support shaft 9 from easily detaching from the positioning sleeve 8. The insertion of the support shaft 9 and the positioning sleeve 8 facilitates the installation and disassembly of the support shaft 9. A bracket 10 is rotatably connected to the outside of the support shaft 9. A telescopic rod 11 is installed at the bottom of the bracket 10 to facilitate the scraper 1's operation on high walls. An adjuster 12 is installed on one side of the bracket 10. The adjuster 12 contains a worm gear 13 and a worm 14, which mesh and have a locking function. A handle 15 is rotatably connected to the bottom of the adjuster 12 via a bearing. The worm gear 13 and worm 14 are fixedly connected to the support shaft 9 and the handle 15, respectively. The movement of the worm gear 13 and worm 14... The meshing allows the throttle 15 and the support shaft 9 to transmit power, driving the support shaft 9 to rotate and pushing the scraper 1 to flip, facilitating the adjustment of the scraper 1's angle. The telescopic rod 11 includes a first rod body 111, with a second rod body 112 slidably connected inside the first rod body 111. A bolt 113 is threadedly connected to one side of the first rod body 111, with one end of the bolt 113 extending into the first rod body 111. By sliding the second rod body 112, the overall length of the first rod body 111 and the second rod body 112 can be easily adjusted. As the bolt 113 rotates, one end of it shifts and presses against the second rod body 112, fixing the position of the second rod body 112.

[0023] In summary, this wall-smoothing device for building engineering uses the following steps: The scraper 1 and extension plate 2 are attached together. The mounting bracket 3 on the scraper 1 is rotated, and a threaded rod 5 is internally threaded onto it. One end of the threaded rod 5 is inserted into the first threaded hole 6 in the positioning member 4 on the extension plate 2. The extension plate 2 is fixed in place by the threaded connection between the threaded rod 5 and the first threaded hole 6. This process is repeated to secure the required number of extension plates 2 together. Holding the handle 18 allows for plastering and other work to smooth the wall surface. Because the positioning member 4 has a second threaded hole 7 on one side adjacent to the first threaded hole 6, the extension plate 2 can be perpendicularly attached to the scraper 1. Rotating the threaded rod 5 further facilitates the smoothing of the wall surface. One end of rod 5 is inserted into the second threaded hole 7 for fixation, so that scraper 1 and extension plate 2 respectively fit against the corners of two adjacent walls. If needed, one end of the support shaft 9 inside the bracket 10 of the telescopic rod 11 can be inserted into the bottom positioning sleeve 8 of scraper 1. Under the friction of the sealing ring 17 inside the positioning sleeve 8, the support shaft 9 is fixed. Holding the telescopic rod 11, it is used to work on a high part of the wall. Through the meshing of the worm gear 13 and worm 14 inside the adjuster 12, and the connection of the worm gear 13 and worm 14 to the support shaft 9 and the handle 15 respectively, rotating the handle 15 can cause the support shaft 9 to rotate, adjusting the angle of the support shaft 9 and scraper 1.
