[0018] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. In the description of the present invention, it should be noted that the terms "center," "up," "down," "left," "right," "vertical," "horizontal," "inside," "outside," and the like, indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be construed as limiting the present invention. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0019] The present invention will be further described below with reference to the accompanying drawings.
[0020] like Figure 1-4 As shown, a wall corner plastering device includes a base plate 1, a slide rail bracket 2, a slide rail 3, multiple rollers 4, multiple fixed shafts 5, a support plate 6, a first bolt 8, a support frame 9, a first fixed seat 10 and a scraper structure.
[0021] Specifically, the middle part of the base plate 1 is connected to the slide rail bracket 2, and the slide rail 3 is installed in the slide rail bracket 2. A plurality of rollers 4 are slidably connected to the slide rail 3, and each roller 4 is rotatably connected to the corresponding fixed shaft 5. The fixed shaft 5 is evenly connected to the support plate 6. A first threaded hole 7 is provided on the support plate 6, and a first bolt 8 is threadedly connected to the first threaded hole 7. The support plate 6 is detachably connected to the support frame 9 through the first bolt 8. Two first fixed seats 10 are mirror-imaged on the support frame 9. The first fixed seat 10 is detachably connected to a scraper structure for evenly applying cement mortar through a second bolt 17. The slide rail 3 can limit the movement direction of the trowel in the scraper structure, and the upward movement of the trowel can evenly apply the cement mortar on the corners of the wall. This not only simplifies the plastering steps but also ensures the uniformity of the cement mortar application.
[0022] Specifically, the scraper structure includes a trowel 11, two second fixing seats 12, a handle 13 and two fixing nuts 18. A second bolt 17 passes through each first fixing seat 10 and is tightly attached to the corresponding second fixing seat 12. A fixing nut 18 is installed at the other end of the second bolt 17. The two second fixing seats 12 are mirror-connected to the trowel 11, and a handle 13 is provided on the trowel 11.
[0023] Specifically, the trowel 11 is provided with a bevel groove 14, which can store excess cement mortar for easy smoothing; the slide rail bracket 2 is provided with a level bubble 15, which can determine whether the base plate 1 is level; second threaded holes are provided at the four diagonal corners of the base plate 1, and support bolts 16 are threadedly connected to the second threaded holes. A through groove is mirrored on the support frame 9, and the corresponding first bolt 8 passes through the through groove.
[0024] Working principle: Since the ground may be uneven, first turn the support bolts 16 to adjust the height of the base plate 1. Observe the level bubble 15 to determine whether the base plate 1 is level. Then, apply cement mortar to both sides of the inner and outer corners of the wall. The operation steps are as follows;
[0025] First, store cement mortar in the inclined groove 14 of the trowel 11, then contact the tip of the trowel 11 with the bottom of the trowel surface, and then push the trowel 11 upward to apply cement mortar on the wall. When it is about to reach the top, remove the trowel 11 from the support frame 9, and then install the trowel 11 in reverse, contacting the tip of the trowel 11 with the top of the trowel surface, so that the entire wall surface can be coated with cement mortar and smoothed.
[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
