Description

Technical Field

[0001] This utility model relates to the technical field of plastering devices, specifically a plastering device. Background Technology

[0002] Plastering is an important process in building construction, which directly affects the appearance quality and thermal insulation performance of buildings. Traditional plastering methods are usually done manually, which is inefficient and labor-intensive.

[0003] Chinese Patent Publication No. (CN221778921U) discloses a plastering device, including a base, a fixed plate on the top of the base, a fixed shaft fixedly connected to the rear end of the fixed plate, a second connecting block rotatably connected to the center of the fixed shaft, an electric telescopic rod fixedly connected to one side of the second connecting block, a first connecting block fixedly connected to the output end of the electric telescopic rod, a rotating plate on the front side of the fixed plate, a first fixed block symmetrically fixedly connected to the top rear side of the rotating plate, a connecting rod on the front side of the rotating plate, and a plastering board fixedly connected to the front end of the connecting rod.

[0004] In the aforementioned comparative documents, to accommodate different wall tilt angles, an electric telescopic rod is used to drive a rotating plate to rotate around a pivot, allowing for flexible adjustment of the plasterboard's tilt angle. This method facilitates the work and improves construction efficiency to some extent. However, during plastering, the plasterboard is usually tilted at a certain angle to help squeeze out air bubbles and reduce wall defects. If the plasterboard remains horizontal or nearly horizontal, air bubbles in the mortar are often difficult to expel, leading to air bubbles or voids on the wall surface and affecting wall quality. In the comparative documents, the rotating plate is larger than the plasterboard. When the plasterboard is tilted at a certain angle, the rotating plate may come into contact with the mortar, while the other side of the plasterboard may not be in contact with the mortar, thus affecting the uniformity and quality of the plastering work.

[0005] In view of this, the present invention provides a plastering device to solve the above-mentioned technical problems. Utility Model Content

[0006] To address the shortcomings of the aforementioned background technology, this utility model provides a technical solution for a plastering device. It adopts a design where the connecting plate is smaller than the plastering board, so that the connecting plate will not come into contact with the mortar when the plastering board is tilted. At the same time, a quick-release component is provided to facilitate the replacement of the plastering board. In addition, this patent also provides an arc-shaped angle ruler so that users can intuitively observe the tilt angle of the plastering board.

[0007] This utility model provides the following technical solution: a plastering device, comprising: a base plate, a hydraulic cylinder, an electric push rod, a plastering board, and a connecting column;

[0008] A top plate is installed at one end of the hydraulic cylinder output rod, and a connecting plate is rotatably connected to the inner cavity of the top plate. A quick-release assembly is fixed on the rear surface of the connecting plate for connecting the plastering board.

[0009] The quick-release assembly includes two fixing plates, which are fixed to the rear surface of the connecting plate. A first clamping block is rotatably connected to the inner cavity of the fixing plate, and a second clamping block is rotatably connected to the surface of the first clamping block. Springs are fixed to the opposite surfaces of the first clamping block and the fixing plate, and the inner cavities of the first clamping block and the second clamping block are engaged with a locking block. The rear surface of the locking block is fixedly connected to the surface of the plastering board.

[0010] Angle rulers are fixed on both sides of the connecting plate.

[0011] As a preferred embodiment of this utility model, the top of the connecting plate has two clearance grooves.

[0012] As a preferred embodiment of this utility model, one end of the two springs is fixedly connected to the rear surface of the fixing plate, and the other end of the two springs is fixedly connected to the surfaces of the first clamping block and the second clamping block, respectively.

[0013] As a preferred embodiment of this utility model, multiple mounting plates are installed on both sides of the base plate, and a knob is threadedly connected to the inner cavity of the mounting plate, with a base fixed to one end of the knob.

[0014] As a preferred embodiment of this utility model, the base is first fixed with a pad.

[0015] As a preferred embodiment of this utility model, the surfaces of the first clamping block and the second clamping block are rounded.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The connecting plate design adopted in this utility model is smaller than the plastering board. When the plastering board is tilted, the connecting plate will not come into contact with the mortar, avoiding the problem that one side of the rotating plate is in contact with the mortar while the other side of the plastering board cannot come into contact with the mortar, thus ensuring the uniformity and consistency of the plastering operation.

[0018] 2. This utility model facilitates the replacement of plasterboards by using quick-release components on the connecting plate, thereby improving work efficiency. Users can quickly and easily replace plasterboards without spending a lot of time and effort, thus reducing labor intensity.

[0019] 3. This utility model also includes an arc-shaped angle ruler, which allows the user to visually observe the tilt angle of the plasterboard when it is tilted, ensuring the accuracy of the plastering operation, improving work efficiency and reducing operational difficulty.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1,

[0027] Please see Figure 1-4As shown, a plastering device includes a base plate 1, a hydraulic cylinder 101, an electric push rod 102, a plastering board 103, and a connecting column 104. A top plate 2 is mounted on one end of the output rod of the hydraulic cylinder 101. A connecting plate 201 is rotatably connected to the inner cavity of the top plate 2. A quick-release assembly is fixed to the rear surface of the connecting plate 201 for connecting the plastering board 103. The quick-release assembly includes two fixing plates 3, which are fixed to the rear surface of the connecting plate 201. A first clamping block 301 is rotatably connected to the inner cavity of the fixing plate 3. The surface of the first clamping block 301 rotates... A second clamping block 302 is movably connected. Springs 303 are fixed to the opposite surfaces of the first clamping block 301 and the fixing plate 3, and to the opposite surfaces of the second clamping block 302 and the fixing plate 3. A clamping block 304 is engaged in the inner cavities of the first clamping block 301 and the second clamping block 302. The rear surface of the clamping block 304 is fixedly connected to the surface of the plastering board 103. Angle rulers 4 are fixed on both sides of the connecting plate 201. Two clearance grooves 5 are provided at the top of the connecting plate 201. By setting the clearance grooves 5, the clearance grooves 5 mainly prevent the top plate 2 from pressing against the connecting plate 201 and the angle rulers. The stroke of 4 has an impact. One end of each of the two springs 303 is fixedly connected to the rear surface of the fixed plate 3, and the other end of each spring 303 is fixedly connected to the surfaces of the first clamping block 301 and the second clamping block 302, respectively. Multiple mounting plates 6 are installed on both sides of the base plate 1. A knob 601 is threadedly connected to the inner cavity of the mounting plate 6. One end of the knob 601 is fixed to a base 602. By setting the base 602 and rotating the knob 601, the base 602 can be raised or lowered, thereby supporting the base plate 1 and providing stability during device operation. The height of the four bases 602 can be adjusted sequentially according to the ground level to adjust the level of the device. The first base 602 is fixed with a pad 7. The pad 7 is made of rubber and mainly serves to reduce vibration and prevent slippage. The surfaces of the first clamping block 301 and the second clamping block 302 are rounded. By rounding the surfaces of the first clamping block 301 and the second clamping block 302, the locking block 304 can enter the inner cavity of the first clamping block 301 and the second clamping block 302 more easily.

[0028] When plastering a vertical wall, first activate the electric push rod 102 to adjust the angle of the connecting plate 201. At this time, the user can observe the angle of the plastering board 103 through the angle ruler 4. When the plastering board 103 reaches the required angle, turn off the electric push rod 102 and activate the hydraulic cylinder 101. The output rod of the hydraulic cylinder 101 drives the plastering board 103 to move up and down, thereby applying the plaster to the surface of the vertical wall. Since the plastering board 103 is tilted at a certain angle, air bubbles can be squeezed out during the application process, reducing defects on the wall surface.

[0029] When the plastering board 103 needs to be disassembled, simply pull out the plastering board 103. Since the shape of the locking block 304 is the same as the shape of the inner cavity of the first clamping block 301 and the second clamping block 302, the locking block 304 will squeeze the first clamping block 301 and the second clamping block 302 to open them and compress the spring 303. After the locking block 304 is disengaged from the inner cavity of the first clamping block 301 and the second clamping block 302, the first clamping block 301 and the second clamping block 302 will reset under the action of the spring 303.

[0030] When it is necessary to install the plasterboard 103, align the locking block 304 with the inner cavity of the first clamping block 301 and the second clamping block 302, and then insert it for connection. When the surface of the locking block 304 contacts the surface of the first clamping block 301 and the second clamping block 302, the locking block 304 will squeeze the first clamping block 301 and the second clamping block 302 to open them and compress the spring 303. After the locking block 304 enters the inner cavity of the first clamping block 301 and the second clamping block 302, the spring 303 will drive the first clamping block 301 and the second clamping block 302 to reset and clamp the locking block 304, thereby completing the installation of the plasterboard 103.
