[0004] However, the above-mentioned device still has some shortcomings in use. When painting, it is necessary to manually dip the paint frequently, which is troublesome and affects the painting efficiency. At the same time, the brushes on the paint roller will wear out after a period of use, and they cannot be quickly disassembled and installed, making it inconvenient to replace them and limiting their use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a wall paint applicator for building construction, which solves the problems of the need for frequent manual application of paint during painting, which is cumbersome and affects painting efficiency. In addition, the brushes on the paint roller will wear out after a period of use, making them difficult to disassemble and install quickly, and inconvenient to replace, thus limiting their use.

[0006] This utility model provides the following technical solution: a wall plasterer for building construction, including a vertical tube and a brush cylinder. The brush cylinder consists of a shell and a brush. A vertical rod is slidably sleeved inside the vertical tube. A support plate is fixedly connected to the top of the vertical rod. Two vertical plates are fixedly connected to the upper surface of the support plate. Threaded holes are opened on the surface of both vertical plates. Screws are threaded into the interior of both threaded holes. Clamping plates are rotatably installed at opposite ends of the two screws. Connecting discs are rotatably connected to opposite sides of the two clamping plates.

[0007] A discharge pipe is fixedly installed between the top ends of the two vertical plates. Multiple nozzles are connected to the lower surface of the discharge pipe, and a conveying pipe is connected to the surface of the discharge pipe. A pump is installed at the bottom end of the conveying pipe, and the discharge end of the pump is connected to the conveying pipe.

[0008] Preferred technical solution 1: Limiting holes are provided on the surfaces of both vertical plates, and limiting rods are slidably sleeved inside the two limiting holes, with the two limiting rods fixedly connected to the two clamping plates respectively.

[0009] Preferred technical solution 2: A set of insert rods is fixedly connected to the surface of each of the two connecting discs, and slots matching the insert rods are opened on the outer shells at both ends of the brush cylinder.

[0010] Preferred technical solution 3: The portion of the conveying pipe above the support plate is made of rigid material, and the portion of the conveying pipe below the support plate is made of flexible material.

[0011] Preferred technical solution four: The surface of the vertical tube is provided with a movable groove, and a locking rod is slidably sleeved inside the movable groove.

[0013] Compared with existing technologies, this utility model provides a wall painter for building construction, which has the following advantages: In use, the feed pipe at the inlet end of the pump is connected to an external container containing paint material. The paint material is then transported through the conveying pipe to the outlet pipe and evenly sprayed onto the brush cylinder through the nozzle. Painting can then begin without frequent re-dipping of paint material, improving painting efficiency. Furthermore, when the height of the brush cylinder needs adjustment, the locking lever can be pulled outwards to disengage it from the locking slot, allowing the vertical rod to be pulled up or down to adjust the overall length, thus quickly adjusting the height of the brush cylinder for easy adjustment. For painting at the same height, when the brush cylinder needs to be replaced after a period of use, the screw is turned to move the clamping plate, which in turn moves the connecting plate and the insert rod, causing the insert rod to disengage from the slot. This releases the lock on the brush cylinder, allowing it to be quickly removed and replaced. The paintbrush is adjustable in height, suitable for painting walls at different heights. It automatically sprays paint onto the brush cylinder, eliminating the need for frequent manual re-dipping, thus improving painting efficiency. The brush cylinder can be quickly installed and removed for easy replacement. Attached Figure Description

Detailed Implementation

[0018] Please see Figure 1-3 ,

[0019] Example 1: A wall plasterer for building construction includes a vertical tube 1 and a brush cylinder 5. The brush cylinder 5 consists of a shell and a brush. A vertical rod 2 is slidably sleeved inside the vertical tube 1. A support plate 3 is fixedly connected to the top of the vertical rod 2. Two vertical plates 4 are fixedly connected to the upper surface of the support plate 3. Threaded holes 6 are opened on the surface of both vertical plates 4. Screws 7 are threadedly sleeved inside the two threaded holes 6. Clamping plates 8 are rotatably installed on the opposite ends of the two screws 7. Connecting discs 9 are rotatably connected to the opposite sides of the two clamping plates 8.

[0020] A discharge pipe 10 is fixedly installed between the top ends of the two vertical plates 4. Multiple nozzles 11 are connected to the lower surface of the discharge pipe 10. A conveying pipe 12 is connected to the surface of the discharge pipe 10. The conveying pipe 12 is generally made of soft rubber tubing and can be bent. A pump 13 is installed at the bottom end of the conveying pipe 12. The discharge end of the pump 13 is connected to the conveying pipe 12.

[0021] Example 2: The difference between this example and Example 1 is that, in this example, the surfaces of the two vertical plates 4 are provided with limiting holes 14, and the interiors of the two limiting holes 14 are slidably fitted with limiting rods 15. The two limiting rods 15 are fixedly connected to the two clamping plates 8 respectively, which facilitates the restriction of the movement of the clamping plates 8 and facilitates the subsequent installation and disassembly of the brush cylinder 5.

[0022] Example 3: The difference between this example and Example 1 is that a set of insert rods 16 are fixedly connected to the surface of each of the two connecting discs 9, and slots 17 matching the insert rods 16 are opened on both ends of the outer shell of the brush cylinder 5, so that the installation of the brush cylinder 5 is more stable and facilitates subsequent painting.

[0023] Example 4: The difference between this example and Example 1 is that the part of the material conveying pipe 12 above the support plate 3 is made of rigid material, while the part of the material conveying pipe 12 below the support plate 3 is made of flexible material, so as to avoid the upper part of the material conveying pipe 12 from affecting the painting.

[0024] Example 5: The difference between this example and Example 1 is that the surface of the vertical tube 1 is provided with a movable groove 18, and a locking rod 19 is slidably sleeved inside the movable groove 18. The surface of the vertical rod 2 is provided with a row of locking grooves 20 that match the locking rod 19. A spring 21 is sleeved on one end of the outer side of the locking rod 19 to adjust the position of the vertical rod 2, so as to facilitate the adjustment of the overall height.

[0025] Example 6: The difference between this example and Example 1 is that the bottom outer surface of the vertical tube 1 is covered with a rubber sleeve, and the surface of the rubber sleeve is provided with anti-slip texture, which makes it easier for users to operate and more comfortable.

[0026] In summary, this wall painter for building construction, when in use, connects the feed pipe of the feed pump 13 to an external container containing paint material. The paint material is then transported through the feed pipe 12 to the discharge pipe 10 and evenly sprayed onto the brush cylinder 5 via the nozzle 11, allowing painting to begin. This eliminates the need for frequent re-dipping of paint material, improving painting efficiency. To adjust the height of the brush cylinder 5, the lever 19 is pulled outwards to disengage it from the slot 20, allowing the vertical rod 2 to be pulled up or down to adjust the overall length, thus quickly adjusting the height of the brush cylinder 5 for painting at different heights. When brush cylinder 5 needs to be replaced after a period of use, rotating screw 7 moves clamp 8, which in turn moves connecting plate 9 and insert rod 16, causing insert rod 16 to disengage from slot 17. This releases the lock on brush cylinder 5, allowing it to be quickly removed and replaced. This paintbrush is easy and quick to use. The overall height of the paintbrush can be adjusted, making it suitable for painting walls of different heights. It can also automatically spray paint onto brush cylinder 5, eliminating the need for frequent manual dipping, thus improving painting efficiency. Furthermore, brush cylinder 5 can be quickly installed and disassembled for easy replacement.
