[0002] In building construction, paint is a commonly used decorative material, used to coat the surface of buildings to beautify, protect, and decorate. Paint is usually composed of pigments, solvents, thinners, additives, and fillers. It is applied to the walls of buildings by brushing, spraying, or other methods. Roller paint devices are required when applying paint to buildings.

[0003] When encountering high walls, it cannot adapt to the different heights of the wall surface for roller coating. It can only be used to paint the lower wall surfaces, and it is difficult to reach the higher walls. This limits the applicable scenarios of the device and cannot meet the construction needs of various building walls. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wall coating roller device. By pulling the pull plate, the insert block is disengaged from the fixing hole. At this time, pulling the fixing box drives the slider, which in turn drives the support rod. The support rod then drives the brush roller height adjustment, thereby quickly adjusting the coating height. This allows for continuous coating operations on walls at different heights, reducing time wasted due to position adjustments and improving overall construction efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A wall coating roller device for architectural paint includes: a support box serving as the main connecting body; a slider slidably connected to the inner wall of the support box; a support rod fixedly connected to the top of the slider; a brush roller connected to the support rod via an adjusting component; fixed boxes fixedly connected to both sides of the outer wall of the slider; pull plates slidably connected to the inner walls of the fixed boxes; insert blocks fixedly connected to opposite ends of the pull plates; and tension springs provided between the pull plates and the inner walls of the fixed boxes.

[0007] Furthermore, one end of each tension spring is connected to a pull plate, and the other end of each tension spring is connected to the inner wall of the fixed box.

[0008] Furthermore, each of the opposite ends of the pull plate is fixedly connected to a sliding rod, and the outer wall of the sliding rod is slidably connected to the inner wall of the fixed box.

[0009] Furthermore, the inner wall of the support box is provided with multiple fixing holes corresponding to the insert block, and a handle is fixedly connected to the bottom end of the support box.

[0010] Furthermore, the adjustment assembly includes a support platform fixedly connected to the top of the support rod, connecting plates fixedly connected to both sides of the top of the support platform, a rotating shaft rotatably connected to the inner wall of the connecting plate, a turntable fixedly connected to the outer wall of the rotating shaft, the top of the brush roller fixedly connected to the top of the turntable, a fixing plate fixedly connected to the right end of the rotating shaft, a fixing cylinder fixedly connected to the inner wall of the fixing plate, a limit plate slidably connected to the inner wall of the fixing cylinder, and a spring provided between the inner walls of the fixing cylinder and the limit plate.

Detailed Implementation

[0023] 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.

[0024] Reference Figures 1-3 This utility model provides an embodiment of a wall coating roller device for architectural paint, comprising: a support box 1 as the connecting body, a slider 2 slidably connected to the inner wall of the support box 1, a support rod 3 fixedly connected to the top of the slider 2, a brush roller 15 connected to the support rod 3 through an adjustment component, a fixing box 4 fixedly connected to both sides of the outer wall of the slider 2, a pull plate 5 slidably connected to the inner wall of the fixing box 4, an insert block 6 fixedly connected to the opposite end of the pull plate 5, a tension spring 7 provided between the pull plate 5 and the inner wall of the fixing box 4, one end of the tension spring 7 connected to the pull plate 5, and the other end of the tension spring 7 connected to the inner wall of the fixing box 4, a sliding rod 8 fixedly connected to the opposite end of the pull plate 5, the outer wall of the sliding rod 8 slidably connected to the inner wall of the fixing box 4, a plurality of fixing holes 9 provided on the inner wall of the support box 1 corresponding to the insert block 6, and a handle 10 fixedly connected to the bottom end of the support box 1.

[0025] Specifically, during wall roller coating operations, when the coating height needs to be adjusted, the worker pulls the pull plate 5. Under force, the pull plate 5, through its tight connection with the insert block 6, causes the insert block 6 to move synchronously, gradually disengaging it from the fixing hole 9. This releases the locking restriction on the height adjustment section. At this point, the fixing box 4, due to the chain reaction caused by the pull plate 5, is in a freely movable state. The worker then pulls the fixing box 4, causing the connected slider 2 to slide smoothly along a predetermined track. The sliding of the slider 2 further drives the support rod 3 to move linearly. The support rod 3, through a stable mechanical connection with the brush roller 15, will also drive the brush roller 15 to adjust its height. This design allows workers to quickly adjust the coating height without the need for complex auxiliary tools, enabling continuous roller coating operations on walls of different heights. This greatly reduces time wasted due to position adjustments and significantly improves overall construction efficiency. Once the brush roller 15 is adjusted to the appropriate height, the operator releases the pull plate 5. The moment the pull plate 5 loses its external force, the tension spring 7 performs its elastic reset function, pulling the pull plate 5 back with its own elastic force. The pull plate 5 moves under the action of the tension spring 7, again driving the insert block 6 towards the fixing hole 9 until the insert block 6 is precisely inserted into the fixing hole 9. This completes the fixing operation of the brush roller 15 after height adjustment, ensuring that the brush roller 15 remains stable during the roller coating operation and will not change height due to vibration or other external forces. It is worth mentioning that during the entire process of the pull plate 5 moving, the slide rod 8 also slides synchronously inside the fixing box 4. The slide rod 8 acts as a precise guide component, constantly constraining and guiding the movement trajectory of the fixing box 4, preventing misalignment of the fixing box 4 due to uneven force or other factors during movement. This ensures the reliability and stability of the entire height adjustment and fixing structure, providing a solid guarantee for high-quality wall roller coating construction.

[0026] Reference Figure 1 , Figure 4 and Figure 5 The adjustment assembly includes a support platform 11 fixedly connected to the top of the support rod 3. Connecting plates 12 are fixedly connected to both sides of the top of the support platform 11. A rotating shaft 13 is rotatably connected to the inner wall of the connecting plate 12. A turntable 14 is fixedly connected to the outer wall of the rotating shaft 13. The top of the brush roller 15 is fixedly connected to the top of the turntable 14. A fixing plate 16 is fixedly connected to the right end of the rotating shaft 13. A fixing cylinder 17 is fixedly connected to the inner wall of the fixing plate 16. A limit plate 18 is slidably connected to the inner wall of the fixing cylinder 17. A spring 20 is provided between the inner walls of the fixing cylinder 17 and the limit plate 18. A plurality of adjustment holes 21 are provided on the inner wall of the connecting plate 12 corresponding to the pull rod 19. One end of the spring 20 is connected to the limit plate 18, and the other end of the spring 20 is connected to the inner wall of the fixing cylinder 17.

[0027] Specifically, during the wall coating process, if the angle of the brush roller 15 needs to be adjusted, the worker first holds the pull rod 19 and applies force. Under this force, the pull rod 19, thanks to its stable connection with other components, gradually disengages from the adjustment hole 21, successfully releasing the locking restriction on the angle adjustment section and allowing the associated structure to move freely. At this point, the fixing plate 16, due to the chain reaction caused by the pull rod 19, can rotate freely. The worker then rotates the fixing plate 16. As the fixing plate 16 rotates, through a tight mechanical connection, it drives the connected rotating shaft 13 to move in a circular motion. The rotation of the rotating shaft 13 further transmits power, causing the turntable 14 to rotate around its central axis. Since there is a stable assembly relationship between the turntable 14 and the brush roller 15, the rotation of the turntable 14 causes the brush roller 15 to change its angle. Through this series of continuous and precise mechanical transmission processes, the brush roller 15 can contact the wall at a suitable angle. When the brush roller 15 is at the optimal angle, it can evenly apply the paint to the wall surface during rolling, effectively reducing common painting defects such as drips and missed spots, significantly improving the smoothness and aesthetics of the coating, and strongly guaranteeing the quality of wall construction. After the brush roller 15 is adjusted to the appropriate angle position that meets the construction requirements, the construction worker releases the pull rod 19. The moment the pull rod 19 is no longer held by external force, the spring 20 that cooperates with it immediately exerts its elastic restoring characteristic. The spring 20 uses its stored elastic potential energy to quickly bounce the limit plate 18 connected to it. The movement of the limit plate 18 then drives the pull rod 19 to move quickly towards the adjustment hole 21 until the pull rod 19 is accurately inserted into the adjustment hole 21. At this point, the fixed operation of the brush roller 15 after the angle adjustment is completed, ensuring that the brush roller 15 maintains a stable angle during subsequent roller coating operations and will not change the angle due to external forces such as vibration and collision, providing a solid guarantee for continuous, efficient and high-quality wall roller coating construction.

[0028] Working principle: When height adjustment is needed, pull plate 5 is pulled to disengage the insert 6 from the fixing hole 9. Then, pulling the fixing box 4 moves the slider 2, which in turn moves the support rod 3. This movement of the support rod 3 then adjusts the height of the brush roller 15, allowing for rapid adjustment of the coating height. This enables continuous coating of walls at different heights, reducing time wasted due to position adjustments and improving overall construction efficiency. When the desired position is reached, pull plate 5 is released. When pull plate 5 is released, tension spring 7 pulls it, causing the insert 6 to insert into the fixing hole 9 for fixation. As pull plate 5 moves, the sliding rod 8 moves inside the fixing box 4. The sliding rod 8 limits the fixed box 4 during movement. When the angle needs to be adjusted, the pull rod 19 is pulled to disengage it from the adjustment hole 21. At this time, the fixed plate 16 is rotated to drive the rotating shaft 13 to rotate. When the rotating shaft 13 rotates, it drives the turntable 14 to rotate. When the turntable 14 rotates, it drives the brush roller 15 to adjust the angle, so that the roller brush can contact the wall at the best angle, making the paint application more even, reducing drips and missed areas, and helping to improve the smoothness and aesthetics of the coating, ensuring the construction quality. When the adjustment is in the appropriate position, the pull rod 19 is released. When the pull rod 19 is released, the spring 20 will spring the limiting plate 18. When the limiting plate 18 is springed, it drives the pull rod 19 to insert into the adjustment hole 21 for fixation.
