Description

Technical Field

[0001] The utility model relates to the technical field of construction devices, in particular to a leveling device for plastering cement mortar. Background Technique

[0002] Cement mortar is composed of cement, fine aggregate and water, that is, cement + sand + water, and is prepared according to needs. Cement mixed mortar is prepared from cement, fine aggregate, lime and water. They are different concepts, with different names and uses. Among them, cement mortar is mainly used for plastering the inner and outer walls of houses to make the walls smoother and more even, facilitating subsequent construction such as decoration.

[0003] During the process of plastering cement mortar, for example, the plastering of the inner wall of a house, generally, manual plastering tools are used to press and apply the mixed cement mortar bit by bit on the wall for preliminary fixation. After the preliminary fixation of the wall is completed, the staff generally uses a flat aluminum tube, places it on the wall and scrapes it to level the protruding and uneven places in the preliminarily plastered cement mortar. In this process, the main control method is that the staff controls the strength of the hand according to experience for leveling. Since the scraping and leveling strength each time cannot be the same, it is still easy to appear uneven at the connection of adjacent two operations after the leveling of the wall is completed, which will affect the overall flatness of the wall in the later stage and reduce the overall leveling effect.

[0004] Therefore, it is necessary to provide a new leveling device for plastering cement mortar to solve the above technical problems. Content of the Utility Model

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model

[0022] The following describes in detail the specific implementation of the present utility model in conjunction with specific embodiments

[0023] Please refer to Figures 1 to 5 , a cement mortar plastering and leveling device provided by an embodiment of the present utility model, the cement mortar plastering and leveling device includes: a chassis 1

[0024] In an embodiment of the present utility model, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 , two slidably connected sliding frames 3 are provided outside the chassis 1, sliders 41 slidably connected are provided inside both of the two sliding frames 3, a support bracket 4 fixedly connected together is provided at the ends of the two sliders 41, a connecting frame 44 slidably connected is inserted inside the support bracket 4, and a scraping strip 5 slidably connected is inserted inside the connecting frame 44

[0025] It should be noted that: by inserting the scraping strip 5 inside the connecting frame 44 and mounting the connecting frame 44 inside the chassis 1 through the sliding frame 3, when using the device later, when the required scraping and leveling depth is completed, the scraping strip 5 can be directly toggled to make the scraping strip 5 slide inside the sliding frame 3 through the connecting frame 44, so that the wall surface can be smoothly scraped and leveled under the guidance of the sliding frame 3, without the need for the staff to manually control the position of the scraping strip 5. Therefore, the device can achieve better results when scraping and leveling later

[0026] In an embodiment of the present utility model, please refer to Figure 1 and Figure 4, a top frame 2 is inserted into the top of the chassis 1 in a sliding connection manner. Above the interior of the chassis 1, a support bar 11 is fixedly installed. Inside the support bar 11, a first rotating rod 12 is inserted in a threaded connection manner. The top of the first rotating rod 12 is rotatably connected to the bottom wall of the top frame 2, and a first turntable 13 is fixedly connected to the bottom of the first rotating rod 12.

[0027] It should be noted that: by movably inserting the top frame 2 into the interior of the chassis 1, during later use, when the staff controls the first rotating rod 12 to move up and down through the first turntable 13, the top frame 2 can be smoothly driven to move inside the chassis 1, and then the overall height of the device can be smoothly adjusted. Therefore, during the use process, the frame formed by the chassis 1 and the top frame 2 can be smoothly installed in rooms at different heights.

[0028] In an embodiment of the present invention, please refer to Figure 1 and Figure 2 , an auxiliary frame is fixedly connected to the outside of the sliding frame 3 through bolts. The inner wall specifications of the auxiliary frame are the same as those of the inner wall of the sliding frame 3, and a support frame 31 is fixedly installed between the two sliding frames 3.

[0029] It should be noted that: by arranging the auxiliary frame outside the sliding frame 3, during use, the track for the slider 41 to slide in the device can be extended through the splicing of the auxiliary frame, and then the device can be smoothly applicable to walls of different lengths in the later stage. At the same time, in the splicing method, after the use of the device is completed, by disassembling it, the volume of the device can also be reduced, making the device more convenient to carry in the later stage.

[0030] In an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 , a second rotating rod 42 is inserted into the interior of the support frame 4 in a threaded connection manner. A second turntable 43 is fixedly connected to one side of the second rotating rod 42 close to the sliding frame 3, and the other side of the second rotating rod 42 away from the sliding frame 3 is rotatably connected to the outer wall of the connection frame 44.

[0031] It should be noted that: through the arrangement of the second rotating rod 42, during the use process, when the staff controls the second rotating rod 42 to rotate through the second turntable 43, the position of the connection frame 44 inside the support frame 4 can be smoothly adjusted, and then the position of the scraping strip 5 located inside the connection frame 44 can be smoothly adjusted, which is convenient for the staff to adjust the depth of scraping and leveling the wall surface in the later stage.

[0032] It should also be noted that: The interiors of the sliding frame 3, the auxiliary frame, and the connecting frame 44 are all in a convex shape. In the later stage, when the slider 41 and the scraping strip 5 slide, the phenomenon of falling off from the non-end cross-sections of the sliding frame 3, the auxiliary frame, and the connecting frame 44 can be avoided, and thus the sliding in the later stage can be made more stable.

[0033] In the embodiment of the present utility model, please refer to Figure 1 and Figure 4 , on both sides of the outside of the chassis 1, there are convex rods 14 fixedly connected. The two convex rods 14 are on the same horizontal plane, and the outer wall of the convex rod 14 abuts against and is slidably connected to the inner wall of the support frame 31. A limit knob 15 is threadedly sleeved on the outside of the convex rod 14, and the outside of the limit knob 15 abuts against the outer wall of the support frame 31.

[0034] It should be noted that: By arranging the two convex rods 14 on the same horizontal plane, after the support frame 31 is sleeved on the outside of the convex rod 14 in the later stage, the bottom of the support frame 31 can be smoothly in a horizontal state with the bottom of the chassis 1. Then, during the later use process, by controlling the support frame 31 to move on the outer wall of the convex rod 14, fine adjustment of the horizontal position of the sliding frame 3 and the auxiliary frame outside the support frame 31 can be realized. Thus, the ends of the sliding frame 3 and the auxiliary frame after assembly can be smoothly moved to the ends required for scraping and leveling the wall surface, and then the scraping strip 5 can smoothly scrape and level the edge part of the wall surface in the later stage;

[0035] And through the setting of the limit knob 15, when the position of the support frame 31 is adjusted, by controlling the rotation of the limit knob 15, it can abut against the outer wall of the support frame 31, and then the support frame 31 and the convex rod 14 can be smoothly limited and fixed.

[0036] The working principle of the cement mortar plastering and leveling device provided by the present utility model is as follows:

[0037] In the later stage, when using this device, after the staff finishes the preliminary plastering of the wall surface, this device can be taken out, and then the chassis 1 in this device is horizontally placed with the wall surface to be leveled. Then, the first turntable 13 can be controlled to drive the first rotating rod 12 to rotate. At this time, the rotating first rotating rod 12 can smoothly drive the top frame 2 at the top to move inside the chassis 1 until the top of the top frame 2 abuts against the top of the room, and then the chassis 1 can be smoothly fixed in the room;

[0038] Then, auxiliary frames of different lengths can be taken out as needed and fixed to both ends of the sliding frame 3 through bolts, so as to extend the length of the sliding frame 3. Then, the staff can control the second turntable 43 to drive the second rotating rod 42 to rotate as needed. At this time, the rotating second rotating rod 42 can smoothly drive the connecting frame 44 to move outward inside the support frame 4 until the scraping strip 5 inside the connecting frame 44 smoothly abuts against the wall surface to be leveled and reaches the required scraping depth, and then the adjustment of the position of the scraping strip 5 can be completed.

[0039] At this time, the staff can hold the outer wall of the scraping strip 5 with both hands and apply a force to drive the slider 41 at the end of the support frame 4 to slide inside the sliding frame 3 through the connecting frame 44, so as to guide the moving track of the scraping strip 5 through the sliding between the slider 41 and the sliding frame 3, so that the scraping strip 5 can slide stably on the wall surface for scraping, realizing the leveling of the wall surface. And during this process, when the scraping of the upper or lower part of the wall surface is completed, the staff can control the scraping strip 5 to slide in the vertical direction inside the connecting frame 44, and then the position of the scraping strip 5 can be smoothly adjusted, so that the scraping strip 5 can scrape the wall surface more comprehensively. Thus, the scraping and leveling of the wall surface can be successfully completed.
