[0021] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0022] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown in the figure, a plastering device for narrow and long spaces of the present utility model includes a plastering bottom plate 1. One side of the plastering bottom plate 1 is provided with a plastering board 11. On the other side of the plastering bottom plate 1 opposite to the plastering board 11, a handle rod 2 is provided. The plastering bottom plate 1 and the handle rod 2 are rotatably connected through a universal joint 16. The handle rod 2 is a telescopic rod. The plastering bottom plate 1 and the plastering board 11 are provided with a communicating mortar spray outlet 12. The telescopic rod is internally provided with a mortar inlet conduit 4, and the mortar inlet conduit 4 is communicated with the mortar spray outlet 12. Among them, the universal joint 16 is a spherical universal joint. The handle rod 2 is a hollow rod, which is convenient for arranging the mortar inlet conduit 4. The plastering board 11 is a steel plate. Mortar can be pumped into the mortar inlet conduit 4 by a pump and then flow out from the mortar spray outlet 12 to achieve continuous plastering, improve the plastering efficiency and reduce the labor intensity of workers. The shape of the handle rod 2 is a square column or a cylindrical column.
[0023] A plastering device for narrow and long spaces based on the above structure is used for plastering narrow and long spaces. It is composed of a plastering bottom plate 1, a plastering board 11, a universal joint 16, a handle rod 2 and a mortar inlet conduit 4. The structure is simple and the manufacturing cost is low. Among them, the plastering bottom plate 1 and the handle rod 2 are rotatably connected through the universal joint 16. The rotation of the plastering bottom plate 1 relative to the handle rod 2 drives the rotation of the plastering board 11, which is convenient for the plastering board 11 to rotate 360°. The angle of the plastering board 11 entering the narrow space for plastering can be flexibly adjusted, so that the plastering board 11 can enter the narrow space for plastering. There is no need to adjust the mechanism to adjust the width of the plastering board 11. Just rotate the plastering bottom plate 1 to adapt to entering the narrow space, which is very convenient to use. The handle rod 2 is a telescopic rod. When plastering in a long and narrow space, only need to extend and adjust the telescopic rod, which is convenient for the telescopic rod to extend into the long and narrow space for plastering. In summary, a plastering device for narrow and long spaces of the present application has a simple structure, is convenient to use, and is convenient for workers to plaster narrow and long spaces.
[0024] As an implementable manner, as Figure 1 、 Figure 2 shown, the telescopic rod includes a hollow fixed rod and a sleeve rod. One end of the fixed rod is connected to the plastering bottom plate 1. The other end of the fixed rod is slidably sleeved in the sleeve rod. The fixed rod and the sleeve rod are provided with a locking mechanism 22 for restricting the sliding of the fixed rod relative to the sleeve rod. The locking mechanism 22 includes a turning handle, a rotating shaft and a limiting block. The fixed rod is provided with opposite through slots 21, and the through slots 21 extend along the length direction of the fixed rod. The sleeve rod is provided with corresponding through holes, and the through holes correspond to the through slots 21 one by one. One end of the rotating shaft is fixedly connected to the turning handle, and the other end of the rotating shaft passes through the corresponding through hole and the through slot 21 and is fixedly connected to the limiting block. The rotating shaft is rotatably connected in the corresponding through hole and through slot 21. The length dimension of the limiting block is the same as the height dimension of the fixed rod, and the axial dimension of the turning handle is greater than the radial dimension of the through hole.
[0025] The length dimension of the limit block is the same as or slightly smaller than the height dimension of the fixed rod. In the initial state, the bottom and top surfaces of both ends of the cuboid-shaped limit block are in contact with or abutted against the inner bottom and inner top surfaces of the fixed rod. The limit block plays a role in limiting the sleeve rod and restricts the relative sliding of the sleeve rod with respect to the fixed rod. When plastering a narrow space, rotate the handlebar in the reverse direction, which drives the rotating shaft to rotate, drives the limit block to rotate, and separates the bottom and top surfaces of both ends of the limit block from the inner bottom and inner top surfaces of the fixed rod. The limit block cancels the limiting effect on the sleeve rod, and the sleeve rod is pushed to slide away from the fixed rod. The telescopic rod extends. When it reaches a suitable length for the narrow space to plaster the narrow space, rotate the handlebar in the forward direction, which drives the rotating shaft to rotate, drives the limit block to rotate, and makes the bottom and top surfaces of both ends of the limit block in contact with or abutted against the inner bottom and inner top surfaces of the fixed rod. The limit block plays a role in limiting the sleeve rod and restricts the relative sliding of the sleeve rod with respect to the fixed rod. The process of shortening the telescopic rod is the same as the process of extending the telescopic rod. Among them, the locking mechanism 22 can be a relatively through slot 21. The sleeve rod is provided with a through hole, and the bolt sequentially passes through the corresponding through hole and the through slot 21 and is threadedly connected with the nut, which plays a role in limiting the sleeve rod. Or the sleeve rod is provided with opposite threaded holes, and the set screw passes through the threaded hole and presses tightly against the fixed rod, which plays a role in limiting the sleeve rod. The mortar inlet conduit 4 is arranged inside the hollow fixed rod and sleeve rod. The axial dimension of the handlebar is greater than the radial dimension of the through hole, preventing the handlebar from passing through the through hole.
[0026] As an implementable manner, as Figure 3 shown, the plastering bottom plate 1 is provided with a water spray port 23, and a water inlet conduit 5 is arranged inside the telescopic rod. The water inlet conduit 5 is communicated with the water spray port 23.
[0027] The arrangement of the water inlet conduit 5 and the water spray port 23 facilitates directly watering and soaking the base layer after cleaning to accelerate the plastering progress, without the need to separately use equipment to water and soak the base layer after cleaning the base layer, which is very convenient. Water can be pumped into the water inlet conduit 5 through a water pump and flow out from the water spray port 23 to water and soak the base layer.
[0028] As an implementable manner, as Figure 5 shown, two rows of elastic rope loops 24 are arranged inside the hollow fixed rod along its length direction, and the mortar inlet conduit 4 and the water inlet conduit 5 respectively pass through one row of the elastic rope loops 24.
[0029] The elastic rope loops 24 play a guiding role for the mortar inlet conduit 4 and the water inlet conduit 5, preventing cross-interference during the extension and shortening of the telescopic rod and affecting the telescopic movement of the telescopic rod. Each row of elastic rope loops 24 is evenly arranged and at least two, such as two or three or four or five, and can be set according to the length of the fixed rod.
[0030] As an implementable manner, as Figure 1 、 Figure 2, Figure 4 As shown in the figure, long-edge scrapers 13 and short-edge scrapers 14 are rotatably arranged at two adjacent edges of the plastering base plate 1. The top surface of the plastering base plate 1 and the side surface of the plastering board 11 form a long-edge scraper groove and a short-edge scraper groove. The long-edge scraper 13 is accommodated in the long-edge scraper groove, and the short-edge scraper 14 is accommodated in the short-edge scraper groove.
[0031] The long-edge scraper 13 and the short-edge scraper 14 are provided for cleaning the base layer in a narrow and long space area before plastering. The long-edge scraper 13 and the short-edge scraper 14 are rotatably arranged, which is convenient for adjusting the angles of the long-edge scraper 13 and the short-edge scraper 14 to adapt to the base layer treatment in different scenarios. After the base layer treatment, the long-edge scraper 13 and the short-edge scraper 14 are rotatably arranged in the long-edge scraper groove and the short-edge scraper groove to prevent interference with the subsequent plastering. The long-edge scraper rotating shaft 17 and the short-edge scraper rotating shaft 15 are respectively fixedly arranged, such as being fixed by threads, at two adjacent long edges and short edges of the plastering base plate 1. The long-edge scraper 13 and the short-edge scraper 14 are provided with through holes, and the long-edge scraper rotating shaft 17 and the short-edge scraper rotating shaft 15 are provided with external threads. The long-edge scraper rotating shaft 17 and the short-edge scraper rotating shaft 15 pass through the corresponding through holes and are rotatably connected to the long-edge scraper 13 and the short-edge scraper 14. Limit nuts 18 are threadedly connected to both sides of the long-edge scraper rotating shaft 17 and the short-edge scraper rotating shaft 15. By tightening the limit nuts 18 on both sides of the long-edge scraper rotating shaft 17 and the short-edge scraper rotating shaft 15, the long-edge scraper 13 and the short-edge scraper 14 are limited, restricting the rotation of the long-edge scraper 13 and the short-edge scraper 14. By loosening the limit nuts 18 on both sides of the long-edge scraper rotating shaft 17 and the short-edge scraper rotating shaft 15, the long-edge scraper 13 and the short-edge scraper 14 can rotate to adjust the angles of the long-edge scraper 13 and the short-edge scraper 14.
[0032] As an implementable manner, as Figure 1 , Figure 2 , Figure 3 , Figure 6 shown, a horizontal stabilizer 3 is arranged at one end of the sleeve rod away from the fixed rod. The horizontal stabilizer 3 includes a sleeve, a U-shaped fixed clamp 31, and a fixed clamp telescopic rod 34. The sleeve is slidably sleeved on the fixed rod. Two fixed clamp telescopic rods 34 are oppositely arranged on the outer wall of the sleeve. The other end of the fixed clamp telescopic rod 34 relative to the sleeve is provided with the U-shaped fixed clamp 31. A screw hole is arranged on one side wall of the U-shaped fixed clamp 31, and a screw rod 32 is threadedly connected to the screw hole.
[0033] When plastering the water and electricity shaft 6, extend or shorten the telescopic rod 34 of the fixed clamp, clamp the fixed clamp 31 on the outer edge 7 of the side wall of the water and electricity shaft, and tighten the screw rod 32 for fixation so that the screw rod 32 abuts against the outer edge 7 of the side wall of the water and electricity shaft. The fixed clamp 31 is clamped and fixed with the outer edge 7 of the side wall of the water and electricity shaft, so that the plastering device for narrow and long spaces will not tilt, preventing the plastering board 11 from tilting during the plastering process, achieving uniform plastering, and ensuring the plastering quality of the plastering device for narrow and long spaces. A nut 33 is arranged outside the screw hole to increase the length of the screw hole, prevent the screw rod 32 from withdrawing from the screw hole, and play a stabilizing role.
[0034] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should be covered within the protection scope of the present invention.
