Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and in particular relates to a leveling device for walls used in decorative engineering. Background Technology

[0002] After the rough walls are constructed, the surface needs to be coated and painted. However, after painting, uneven areas may appear on the wall, requiring scraping to smooth them. Currently, wall smoothing is done manually by using a scraper to remove the coating. However, this method is labor-intensive, inefficient, and the smoothness varies greatly depending on the worker's skill level, making it difficult to guarantee quality. Therefore, a more automated leveling device is needed.

[0003] For example, Chinese patent application CN202110198639.5 discloses a building wall leveling device, relating to the field of building construction technology. This invention includes a movable base, within which a lifting frame is slidably fitted; a connecting frame is sleeved between the two ends of the lifting frame; two symmetrically arranged scraping guides are slidably fitted on one side of the connecting frame; a servo motor is provided on one side of the connecting frame; a transmission gear that meshes with the two scraping guides is fixed to the shaft end of the servo motor; a push plate is slidably fitted between the two ends inside the scraping guide; scrapers are arrayed on one side of the push plate; and the scrapers are slidably fitted on both sides of the scraping guide.

[0004] The aforementioned wall leveling equipment has a limited leveling range with its scraper, resulting in numerous scratches that require manual leveling by workers using a scraper. This leads to a significant amount of repair work later on. Furthermore, the excess putty scraped off the scraper needs to be cleaned frequently during leveling, adding to the burden of the leveling operation.

[0005] Therefore, the existing leveling devices are not effective and cannot meet the needs of actual use. There is an urgent need for improved technologies to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a leveling device for decorative wall surfaces. By setting an adjustment component, the angle of the square tube can be adjusted. When the side wall of the square tube is parallel to the wall, it is used to scrape off excess material during leveling. When the square tube is obliquely cut to the wall, excess material at the top of the square tube will fall along the oblique surface to fill the gaps in the wall. By setting the angle of the adjustable ribs, it achieves a high degree of conformity with manual leveling, improves leveling efficiency, and solves the problem of poor performance of existing leveling devices.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0012] Furthermore, the rack frame has a U-shaped structure.

[0013] Furthermore, the adjustment assembly includes a lead screw rotatably mounted on the top of the movable plate, guide rods fixedly mounted on both sides of the lead screw, and a sliding sleeve slidably mounted on a pair of guide rods. The inner wall of the sliding sleeve is threaded, and the lead screw is threadedly connected to the sliding sleeve. The adjustment assembly also includes a limiting assembly for driving the square tube to rotate, and the limiting assembly is connected to the sliding sleeve.

[0014] Furthermore, the limiting component includes a movable block slidably mounted on a pair of guide rods. The movable block has multiple circumferentially distributed sliding holes.

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] Please see Figures 1-4As shown, this invention is a leveling device for decorative wall surfaces, comprising a movable base 1 and a guide frame 9 detachably mounted on one side of the movable base 1. Two straight rods on the guide frame 9 are threadedly connected to the movable base 1. The guide frame 9 can be disassembled by screwing the straight rods. This design facilitates easy assembly and disassembly of the entire device and makes it convenient for transportation. A movable plate 6 is slidably mounted on the guide frame 9. The top of the movable base 1 has an integrally formed receiving cavity, within which a folding mechanism is provided for driving the movable plate 6 to rise and fall. The folding mechanism is connected to the movable plate 6 and includes a pair of rotating rods 2 rotatably mounted on the inner wall of the receiving cavity of the movable base 1. One of the rotating rods 2 has threads on its outer wall, and a slider 4 is movably mounted on the rotating rod 2. A hinge seat 3 is fixedly mounted on one side of the slider 4, and an electric motor is hinged to the top of the hinge seat 3. The top of the push rod 5 is rotatably connected to the bottom of the moving plate 6. When the equipment needs to be moved, the handwheel on one side of the rotating rod 2 is turned to rotate the rotating rod 2. The rotating rod 2 is threadedly connected to the slider 4, which drives the slider 4 to move on the rotating rod 2. The electric push rod 5 rotates around the hinge seat 3 and pulls the moving plate 6 downward until the electric push rod 5 is in a horizontal state. It also includes a leveling unit, which pushes the square tube 7 to level the front. A pair of L-shaped frames 10 are fixedly installed on the side wall of the moving plate 6. The leveling unit is connected to the L-shaped frames 10. A U-shaped groove 24 is opened on the horizontal section of the L-shaped frame 10. A right angle plate 8 is slidably installed in the pair of U-shaped grooves 24. The included angle of the right angle plate 8 is 90 degrees. The advantage of this setting is that it is convenient for workers to use an auxiliary scraper to fit with the included angle and clean off the excess material in the right angle plate 8.

[0032] Among them, such as Figures 1-5As shown, the leveling unit includes a first mounting rod 11 and a second mounting rod 12 rotatably mounted on an L-shaped frame 10. A pair of U-shaped blocks 17 are fixedly sleeved on the second mounting rod 12. The U-shaped blocks 17 are clamped and fixed to the square tube 7 by bolts. The advantage of this arrangement is that it can clamp the aluminum alloy square tubes on the existing construction site, and its application range is relatively wide. A transmission wheel 13 is fixedly sleeved at the central position of both the second mounting rod 12 and the first mounting rod 11. The pair of transmission wheels 13 are connected by a synchronous belt drive. A pair of L-shaped frames A fixed rod 16 is fixedly installed between 10. A rack frame 15 is slidably installed on the fixed rod 16. A first spring is fixedly installed between the rack frame 15 and the fixed rod 16. The rack frame 15 has a U-shaped structure. A rack is installed at the vertical section of the rack frame 15. A pair of gears 14 are fixedly sleeved on the first mounting rod 11 at the corresponding position of the rack. The gears 14 mesh with the rack. The leveling unit also includes an adjustment component, which is used to adjust the angle of the second mounting rod 12. The adjustment component is connected to the rack frame 15. The adjustment assembly includes a lead screw 18 rotatably mounted on the top of the movable plate 6. Guide rods 19 are fixedly mounted on both sides of the lead screw 18. A sliding sleeve 22 is slidably mounted on the pair of guide rods 19. The inner wall of the sliding sleeve 22 is threaded. The lead screw 18 and the sliding sleeve 22 are threadedly connected. The adjustment assembly also includes a limiting assembly, which is used to drive the square tube 7 to rotate. The limiting assembly is connected to the sliding sleeve 22. When adjusting the angle of the rib 7, the handwheel at the top of the lead screw 18 is rotated, causing the sliding sleeve 22 to move on the body of the lead screw 18. The sliding sleeve 22 drives the rack frame 15 to slide in the fixed rod 16 through the limiting assembly. The rack frame 15 meshes with the gear 14, driving the first mounting rod 11 to rotate. The first mounting rod 11 and the second mounting rod 12 are driven by the transmission wheel 13, driving the U-shaped block 17 to rotate. The angle of the rib 7 is adjusted according to the thickness of the wall putty. This application, by setting an adjustment component, can adjust the angle of the square tube. When the side wall of the square tube is parallel to the wall, it is used to scrape off excess material during leveling. When the square tube is obliquely cut to the wall, excess material at the top of the square tube will fall along the oblique surface to fill the gap. By setting the angle of the adjustment rib 7, the effect of high fit with manual leveling is achieved, improving leveling efficiency.

[0033] Among them, such as Figures 3-6As shown, the limiting assembly includes a movable block 23 slidably mounted on a pair of guide rods 19. The movable block 23 has multiple circumferentially distributed sliding holes. A short rod 30 is fixedly installed inside each sliding hole. A second spring is sleeved on the short rod 30, and a rectangular block 29 is slidably mounted thereon. A U-shaped frame 28 is fixedly mounted on the top of the rectangular block 29. A pair of ear blocks are fixedly mounted on the top of the movable block 23 at corresponding positions of the sliding holes. A pressure block 26 is rotatably mounted on the ear blocks via a rotating shaft. A guide groove is provided at one end of the pressure block 26, extending to contact the U-shaped frame 28. A circular hole is provided at the center of the movable block 23. A rotating sleeve 27 is rotatably fitted inside the circular hole. There is significant friction between the rotating sleeve 27 and the movable block 23. Multiple... The L-shaped grooves are arranged in a circular pattern, and the corners of the L-shaped grooves are rounded for a smooth transition. The other end of the pressure block 26 extends to contact the rotating sleeve 27. An arc-shaped section is integrally formed at the center of the pressure block 26. The advantage of this design is that it can fit the L-shaped groove of the rotating sleeve 27. By rotating the rotating sleeve 27, the angle of the pressure block 26 can be adjusted. A pedal 21 is fixedly installed on one side of the rotating sleeve 27. A second guide wheel frame 25 is fixedly installed on the side wall of the fixed rod 16 and the moving plate 6. A first guide wheel frame 20 is fixedly installed on the top of the moving plate 6 at the corresponding position of the second guide wheel frame 25. A pull rope is fixedly installed on one end of the moving block 23. The other end of the pull rope is wrapped around the first guide wheel frame 20 and the second guide wheel frame 25 and fixedly connected to the rack frame 15.

[0034] Working principle: First, move the movable base 1 to the designated position. The ribs are fixed to the wall surface with plaster after pre-measurement. Then, the ribs 7 are installed on a pair of U-shaped blocks 17. The electric push rod 5 extends, causing the L-shaped frame 10 to rise on the guide frame 9. The ribs 7 are then in contact with the wall surface, and excess putty is scraped off. After leveling, the ribs 7 descend, and some putty accumulates on the top of the ribs 7. By moving the movable base 1, the ribs 7 are moved away from the wall. Then, the pedal 21 is rotated counterclockwise. At this time, the arc segment of the pressure block 26 contacts the inward section of the L-shaped groove of the rotating sleeve 27, and the second spring releases elastic potential energy, causing the rectangular block 29 to slide on the short rod 30. The rectangular block 29 slides through the U-shaped frame... 28 drives one end of the pressure block 26 to rotate away from the sliding sleeve 22. At this time, the sliding sleeve 22 is disconnected from the moving block 23. By stepping on the pedal 21, the pedal 21 pulls the pull rope through the moving block 23. One end of the pull rope pulls the rack frame 15 downward and squeezes the spring, which meshes with the gear 14. Through the transmission wheel 13, the second mounting rod 12 is rotated. The side of the rib 7 with putty accumulated rotates to the top of the right angle plate 8, so that the putty falls into the right angle plate 8, making it convenient for workers to scrape and clean. After the pouring is completed, the pedal 21 is reset, so that the pressure block 26 is connected to the sliding sleeve 22. This achieves quick cleaning and leveling of the excess putty, improves leveling efficiency, and has a simple structure that is easy to disassemble and assemble, bringing convenience to leveling operations.

[0035] The above are merely preferred embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present invention.
