Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a wall plastering leveler. Background Technology

[0002] Leveling the wall surface after applying mortar is an essential step. Currently, the common practice is to manually level it using a wooden or aluminum alloy scraper. Ordinary scrapers are made of wood or aluminum alloy, and the operator holds the scraper with both hands and scrapes the finished plaster surface to level it. This method is not only slow and labor-intensive, but also makes it difficult to control the thickness of the plaster layer, and the flatness of the plaster surface is greatly affected by the operator's skill level. In order to improve this situation, a wall plaster leveling tool is proposed.

[0003] For example, the wall plastering device for building engineering disclosed in the authorization announcement number CN222276067U includes a horizontal bar and a mixing box. Support frames are inserted into the bottom of both ends of the horizontal bar. Sliding sleeves are sleeved on the outside of the support frames. A bracket is connected between the two sliding sleeves. A convex groove is opened inside the bracket. A convex block is slidably connected inside the convex groove. A frame is connected to the bottom of the convex block. A nozzle is installed on one side of the frame. A mud pump is installed on one side of the mixing box.

[0004] Although it achieves the lifting and lowering of the frame and the displacement of the spray nozzle and scraper below by the winding and unwinding of the hoisting rope and the meshing of the first gear in the convex block and the first rack in the bracket, it can flexibly adjust its position, making it convenient to replace manual plastering, facilitate high-altitude operations, and improve efficiency. At the same time, by using the rotation of the scraper, the distance between the bottom of the scraper and the wall can be adjusted according to the thickness of the plaster.

[0005] However, it does not solve the problem that existing leveling tools are not conducive to flexibly adjusting and adapting to different plastering areas and reciprocating to scrape and level cement surfaces, making it difficult to perform preliminary leveling of plastering areas in advance and to adjust and scrape and level different positions, thus affecting the efficiency of wall leveling. Utility Model Content

[0006] The purpose of this utility model is to provide a wall plastering leveler to solve the problems mentioned in the background art, such as the difficulty in flexibly adjusting and adapting to different plastering areas and reciprocating oscillation to scrape and level cement surfaces, which makes it difficult to perform preliminary leveling of the plastering area in advance and adjust and scrape and level different positions, thus affecting the efficiency of wall leveling.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wall plastering leveling device, comprising tracks and adjusting rods. The tracks are in two sets, with adjusting rods symmetrically installed on the sides of each track. A telescopic rod is provided between each set of adjusting rods, and the telescopic rod is slidably connected to the adjusting rod. A first locking pin is provided on the side wall of each adjusting rod, extending through the adjusting rod into the interior of the telescopic rod and threadedly connected to it. A slider is provided inside each track, and the slider is slidably connected to the track. An integrated frame is installed on the sides of each set of sliders, and a second locking pin is provided on the outer wall of the track on the slider side, extending through the track into the interior of the slider and threadedly connected to it.

[0008] Preferably, threaded sleeves are symmetrically installed on the sidewalls of the track, and each threaded sleeve has an installation buckle inside, which is threadedly connected to the threaded sleeve.

[0009] Preferably, each of the side walls of the integrated frame is equipped with a stepper motor, and each stepper motor has a worm gear installed at its output end.

[0010] Preferably, worm wheels are movably installed inside the integrated frame on one side of the worm, and the worm wheels mesh with the worm.

[0011] Preferably, each of the worm gears has a long connecting arm on its sidewall, and each long connecting arm has a linkage shaft at the end near the worm gear, and the long connecting arm is movably connected to the worm gear through the linkage shaft.

[0012] Preferably, each of the long connecting arms has a short connecting arm at the end away from the worm gear, and each of the short connecting arms has a hinge shaft at the end near the long connecting arm, and the short connecting arm is movably connected to the long connecting arm through the hinge shaft.

[0013] Preferably, each of the short connecting arms has a movable shaft fixedly installed at the end away from the long connecting arm, and the movable shaft is movably connected to the integrated frame, and the movable shaft extends to the outside of the integrated frame.

[0014] Preferably, a scraper is provided at the end of the movable shaft away from the integrated frame, and the scraper is fixedly connected to the movable shaft.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the leveler not only realizes flexible adjustment to adapt to different ranges of plastering areas and reciprocating oscillation to scrape and level the cement surface, which facilitates the preliminary leveling of the plastering area in advance and the adjustment and scraping of different positions, but also improves the efficiency of wall leveling.

[0016] (1) Unscrew the first locking pin to separate the telescopic rod from the adjusting rod. Pull the adjusting rod and slide it on the surface of the telescopic rod to make the two sets of adjusting rods move away from each other. After adjusting to the usable width, tighten the first locking pin again to fix the telescopic rod and the adjusting rod together so that the track, adjusting rod and telescopic rod form a frame. Take the frame and let the frame drive the mounting buckle to stick to the wall. Use a laser level to project a horizontal laser line according to the site structure. At this time, rotate multiple sets of mounting buckles. The mounting buckles move inside the threaded sleeve. The different moving distances of the mounting buckles in the threaded sleeve can drive the corresponding corner of the frame to move closer to or away from the wall until the frame is completely aligned with the laser line. This ensures that the plaster surface inside the frame is level after the plastering construction. Then fix the mounting buckles to the wall with bolts. Manually plaster the wall within the frame area to make the plaster surface consistent with the frame plane. This achieves convenient and flexible adjustment to adapt to different plastering areas and facilitates the initial leveling of the plastering area in advance.

[0017] (2) Install the integrated frame on the slider so that the scraper is attached to the cement surface. The stepper motor drives the worm to rotate, the worm drives the worm wheel to rotate, the worm wheel drives the long connecting arm to swing back and forth through the linkage shaft, the long connecting arm drives the short connecting arm to swing back and forth through the hinge shaft, the short connecting arm drives the movable shaft to rotate back and forth, the movable shaft drives the scraper to swing back and forth. The scraper swings back and forth to scrape the cement surface to remove the cement that protrudes from the horizontal surface, thereby leveling the cement. After the cement in a certain area is leveled, loosen and pull out the second locking pin, move the slider, and the slider drives the integrated frame and scraper to move. After moving to the new leveling area, reinsert the second locking pin to fix the slider to the track. Then repeat the above operation to scrape and level the new leveling area. This realizes the reciprocating swing scraping to level the cement surface, which is convenient for adjusting the scraping and leveling in different positions and improves the efficiency of wall leveling.

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] Please see Figure 1-5 The present invention provides an embodiment of a wall plastering leveler, comprising a track 1 and an adjusting rod 7. The track 1 consists of two sets, and adjusting rods 7 are symmetrically installed on the side of each set of track 1 that is close to each other. A telescopic rod 6 is provided between each set of adjusting rods 7. The telescopic rod 6 is slidably connected to the adjusting rod 7. A first locking pin 5 is provided on the side wall of each adjusting rod 7. The first locking pin 5 passes through the adjusting rod 7 and extends into the interior of the telescopic rod 6 and is threadedly connected to the telescopic rod 6. A slider 10 is provided inside each track 1, and the slider 10 is slidably connected to the track 1. An integrated frame 3 is installed on the side of each set of sliders 10 that is close to each other. A second locking pin 2 is provided on the outer wall of the track 1 on the side of the slider 10. The second locking pin 2 passes through the track 1 and extends into the interior of the slider 10 and is threadedly connected to the slider 10.

[0026] Threaded sleeves 9 are symmetrically installed on the side walls of track 1. Each threaded sleeve 9 has a mounting buckle 8 inside, and the mounting buckle 8 is threadedly connected to the threaded sleeve 9.

[0027] When plastering is required on the wall, first unscrew the first locking pin 5 to separate the telescopic rod 6 from the adjusting rod 7. Pull the adjusting rod 7, allowing it to slide on the surface of the telescopic rod 6, thus distancing the two sets of adjusting rods 7 from each other. After adjusting to the desired width, retighten the first locking pin 5 to secure the telescopic rod 6 and adjusting rod 7 together, forming a frame from the track 1, adjusting rod 7, and telescopic rod 6. Remove this frame, allowing it to engage the mounting clips 8 to adhere to the wall. Use a laser level to project a horizontal laser line based on the site structure. Then, rotate multiple sets of... Installing buckle 8 moves inside threaded sleeve 9. The different moving distances of installing buckle 8 within threaded sleeve 9 can move a corresponding corner of the frame closer to or further away from the wall until the frame is completely aligned with the laser line. This ensures that the plaster surface inside the frame is level after plastering. Then, the installing buckle 8 is fixed to the wall with bolts, and the plaster is applied manually to the wall within the frame area to make the plaster surface consistent with the frame plane. This allows for convenient and flexible adjustment to adapt to different plastering areas and facilitates preliminary leveling of the plastering area in advance.

[0028] Stepper motors 11 are installed on the side walls of the integrated frame 3. The stepper motors 11 serve as power drives, and worm gears 12 are installed at the output ends of the stepper motors 11.

[0029] Worm gears 18 are movably installed inside the integrated frame 3 on one side of the worm 12, and the worm gears 18 mesh with the worm 12. Long connecting arms 14 are provided on the side wall of the worm gears 18, and a linkage shaft 13 is provided at the end of the long connecting arm 14 near the worm gear 18. The long connecting arm 14 is movably connected to the worm gear 18 through the linkage shaft 13.

[0030] Each end of the long connecting arm 14 away from the worm gear 18 is provided with a short connecting arm 16, and each end of the short connecting arm 16 near the long connecting arm 14 is provided with a hinge shaft 15, and the short connecting arm 16 is movably connected to the long connecting arm 14 through the hinge shaft 15.

[0031] A movable shaft 17 is fixedly installed at the end of the short connecting arm 16 away from the long connecting arm 14, and the movable shaft 17 is movably connected to the integrated frame 3. The movable shaft 17 extends to the outside of the integrated frame 3. A scraper 4 is provided at the end of the movable shaft 17 away from the integrated frame 3, and the scraper 4 is fixedly connected to the movable shaft 17.

[0032] After plastering is completed, the plaster surface needs to be leveled. The integrated frame 3 is installed on the slider 10, so that the scraper 4 is in contact with the cement surface. The stepper motor 11 is turned on, driving the worm gear 12 to rotate. Under the meshing of the worm gear 12 and the worm wheel 18, the worm gear 12 drives the worm wheel 18 to rotate. The worm wheel 18, through the linkage shaft 13, drives the long connecting arm 14 to reciprocate. The long connecting arm 14, through the hinge shaft 15, drives the short connecting arm 16 to reciprocate. The short connecting arm 16 drives the movable shaft 17 to rotate reciprocally. The movable shaft 17 drives the scraper 4 to reciprocate, and the scraper 4 is used to clean the cement surface. The cement is scraped away by reciprocating oscillation to smooth it out. After a certain area of ​​cement is smoothed, the second locking pin 2 is loosened and pulled out, and the slider 10 is moved. The slider 10 drives the integrated frame 3 and scraper 4 to move to a new smooth area. After moving to a new smooth area, the second locking pin 2 is reinserted to fix the slider 10 to the track 1. The above operation is repeated to smooth the new smooth area. This reciprocating oscillation scraping smooths the cement surface, making it convenient to adjust the scraping and smoothing at different positions and improving the efficiency of wall smoothing.

[0033] Working Principle: When plastering is required on the wall, unscrew the first locking pin 5 to separate the telescopic rod 6 from the adjusting rod 7. Pull the adjusting rod 7, which slides on the surface of the telescopic rod 6, moving the two sets of adjusting rods 7 away from each other. After adjusting to the usable width, retighten the first locking pin 5 to fix the telescopic rod 6 and adjusting rod 7 together, forming a frame with the track 1, adjusting rod 7, and telescopic rod 6. Remove the frame, which will cause the mounting buckles 8 to adhere to the wall. Using a laser level, a horizontal laser line is projected according to the site structure. Then, rotate multiple sets of mounting buckles 8, which move within the threaded sleeve 9. The different movement distances of the mounting buckles 8 within the threaded sleeve 9 move a corresponding corner of the frame closer to or further away from the wall until the frame is completely aligned with the laser line. This ensures that the plaster surface within the frame is level after plastering. Finally, fix the mounting buckles 8 to the wall with bolts. Then, manually apply plaster to the wall within the frame area, ensuring the plaster surface is level with the frame. The frame plane should remain consistent. After plastering, the plaster surface needs to be leveled. Install the integrated frame 3 on the slider 10, so that the scraper 4 is in contact with the cement surface. The stepper motor 11 drives the worm gear 12 to rotate, which in turn drives the worm wheel 18 to rotate. The worm wheel 18 drives the long connecting arm 14 to swing back and forth through the linkage shaft 13. The long connecting arm 14 drives the short connecting arm 16 to swing back and forth through the hinge shaft 15. The short connecting arm 16 drives the movable shaft 17 to rotate back and forth, and the movable shaft 17 drives the scraper 4. The scraper 4 reciprocates and scrapes the cement surface to remove cement protruding from the horizontal surface, thus leveling the cement. After a certain area of ​​cement is leveled, the second locking pin 2 is loosened and pulled out, and the slider 10 is moved. The slider 10 drives the integrated frame 3 and the scraper 4 to move. After moving to a new leveling area, the second locking pin 2 is reinserted to fix the slider 10 to the track 1. Then, the above operation is repeated to scrape and level the new leveling area.
