[0002] With the continuous development of the construction industry, the demand for painting tools in construction projects is increasing. Roller brushes are commonly used tools in construction projects. Roller brushes are divided into three types: long-bristled, medium-bristled, and short-bristled. As a painting tool, roller brushes are often used for applying fluid paints, such as latex paint, anti-rust paint, interior and exterior wall paints, and wallpaper paste. Due to their wide rolling surface range, they can easily paint walls or ceilings and are widely used in the construction and decoration industry.

[0003] When using a roller brush, the brush head needs to be placed into the paint bucket to adhere and absorb the paint. Due to uneven paint adhesion, excess paint will flow and drip from the top of the brush head when the brush head is picked up and moved. This not only leads to paint waste, but also results in poor uniformity of paint application on the wall due to uneven paint distribution, affecting the painting effect. Therefore, a roller brush for construction engineering is proposed. Utility Model Content

[0024] Please see Figure 1-5 This utility model provides a technical solution: a roller brush for construction engineering, including a brush head mechanism and a gripping mechanism. The gripping mechanism is used for gripping and supporting the device. The gripping mechanism includes a gripping rod 4 and a telescopic inner rod 5. Both the gripping rod 4 and the telescopic inner rod 5 are made of stainless steel. In order to increase the gripping stability, a rubber sleeve is provided on the outside of the gripping rod 4.

[0025] The telescopic inner rod 5 is inserted and installed inside the front side of the grip rod post 4, as shown in the attached figure. Figure 4As shown, in order to facilitate the connection and installation of the telescopic inner rod 5, a telescopic inner cavity is provided in the middle of the gripping rod post 4. The aperture (i.e., inner diameter) of the telescopic inner cavity is designed to allow the telescopic inner rod 5 and its rear limiting end 6 to be inserted from the rear. The telescopic inner rod 5 is movably inserted and installed inside the telescopic inner cavity from the rear. In order to limit the forward extension of the telescopic inner rod 5, a limiting end 6 is fixedly provided at the rear end of the telescopic inner rod 5. The limiting end 6 is slidably fitted inside the telescopic inner cavity. In order to seal the rear of the telescopic inner cavity, a sealing end cap 7 is fastened to the rear opening side of the telescopic inner cavity by bolts.

[0026] For easy telescopic installation, see attached Figure 4 As shown, a telescopic insertion hole is provided at the front of the telescopic inner cavity. The front end of the telescopic inner rod 5 is movably inserted and installed inside the telescopic insertion hole. In order to achieve installation limitation, mating threads are provided on both the front and rear sides of the telescopic inner rod 5, and an internal thread is provided on the end side of the gripping rod 4. Two sets of mating threads are respectively provided on the front and rear ends of the telescopic inner rod 5, and the internal thread is provided on the inner circumference of the telescopic insertion hole. By cooperating with the internal thread on the end side of the gripping rod 4, the telescopic inner rod 5 can be tightened and locked in the retracted and extended states, realizing the switching and adjustment of different support heights of the gripping structure. The structure is simple and easy to use. By telescopic switching adjustment, the roller brush can meet the painting construction needs of walls of different heights, greatly improving the flexibility of the device.

[0027] The brush head mechanism is installed at the end of the telescopic inner rod 5 for wall painting. The brush head mechanism includes a roller brush head 1, a scraper rod 2, and a brush head mounting bracket 3, as shown in the attached diagram. Figure 3 As shown, in order to facilitate connection and installation with the brush head mounting bracket 3, a mounting block 8 is fixedly installed at the front end of the telescopic inner rod 5, and the rear end of the brush head mounting bracket 3 is fixedly installed with the mounting block 8. The roller brush head 1 is provided with a support roller core inside. The roller brush head 1 is mounted on the shaft column side at the front of the brush head mounting bracket 3 by the support roller core to support the fixed axis rotation, as a coating structure.

[0028] To apply the paint, the scraper bar 2 is installed on the rear side of the roller brush head 1, as shown in the attached diagram. Figure 5As shown, to facilitate the connection and installation of the scraper rod 2, mounting bushings 9 are fixed on both sides of the front part of the scraper rod 2. The mounting bushings 9 are movably connected to the shaft side of the front part of the brush head mounting frame 3, allowing the scraper rod 2 to rotate axially. To limit the installation of the scraper rod 2, a limiting buckle 10 is fixedly installed on one end of the scraper rod 2. The limiting buckle 10 is fitted and snapped into the side of the brush head mounting frame 3 to limit the rotation of the scraper rod 2 after installation. The scraper rod 2 is coaxially installed with the roller brush head 1 using the mounting bushings 9 and limited by the limiting buckle 10. It is easy to use and install. When dipping the paint, the side rotation of the scraper rod 2 can scrape the dipped paint evenly, which can avoid paint dripping and waste and improve the uniformity of paint distribution on the upper part of the roller brush head 1, which is beneficial to improving the wall painting effect. In order to guide and recover the scraped paint, a guide elbow 11 is provided on the other end of the scraper rod 2.

[0029] Working principle or structural principle: The scraper rod 2 is pre-installed on the outside of the roller brush head 1. During use, the length of the holding mechanism is adjusted according to the needs of the brushing construction. When brushing low walls, the telescopic inner rod 5 is kept in the retracted state. The connecting thread at the front end of the telescopic inner rod 5 is connected to the internal thread on the port side of the holding rod column 4 to complete the installation limit between the holding rod column 4 and the telescopic inner rod 5. When brushing high walls, the telescopic inner rod 5 is rotated out of the port of the holding rod column 4 by screwing. Then, the telescopic inner rod 5 is pulled forward to extend it outward. When resistance is felt, it is stopped. Then, the holding rod column 4 is screwed to connect the connecting thread at the rear end of the telescopic inner rod 5 to the internal thread on the port side of the holding rod column 4 to complete the installation limit between the holding rod column 4 and the telescopic inner rod 5, and complete the extension adjustment of the holding part.

[0030] During brushing, the device is held and moved by gripping the rod 4. Then, the roller brush head 1 is dipped into the paint bucket to pick up the paint. After that, the roller brush head 1 is lifted out and placed at an angle on the top of the paint bucket. Then, the roller brush head 1 is rotated by flicking with the fingers. When the roller brush head 1 is rotating, the paint adhering to the upper part of the roller brush head 1 is scraped evenly by the scraper rod 2, so that the paint is evenly distributed on the upper part of the roller brush head 1. At the same time, the scraper can remove the excess paint on the upper part of the roller brush head 1. The scraped paint is guided by the scraper rod 2 and finally flows down from the guide bend 11 into the inside of the paint bucket. Then, the roller brush head 1 is lifted close to the wall and the wall painting is completed by reciprocating.

[0031] In summary, this roller brush adopts a telescopic adjustable gripping mechanism. The telescopic inner rod 5 is movably inserted and installed with the gripping rod column 4, and the two ends of the telescopic inner rod 5 are provided with mating threads. By cooperating with the internal threads on the port side of the gripping rod column 4, the telescopic inner rod 5 can be tightened and locked in the retracted and extended states, realizing the switching and adjustment of different support heights of the gripping structure. The structure is simple and easy to use. Through telescopic switching adjustment, the roller brush can meet the painting construction needs of walls of different heights, greatly improving the flexibility of the device. In addition, a scraper rod 2 is provided on the mounting side of the roller brush head 1. The scraper rod 2 is coaxially installed with the roller brush head 1 using the mounting bushing 9 and is installed and limited by the limiting buckle 10. It is easy to use and install. When dipping paint, the scraper rod 2 can scrape the dipped paint evenly by lateral rotation, which can not only avoid paint dripping and waste, but also improve the uniformity of paint distribution on the upper part of the roller brush head 1, which is conducive to improving the wall painting construction effect.
