[0018] Please see Figures 1-4The present invention provides the following technical solution: it includes a brush roller 1 and a brush handle 11. A docking box 2 is provided below the brush roller 1. A left support frame 21 is installed at one end of the docking box 2. A left connecting ring 22 is installed on the top of the left support frame 21. A right support frame 24 is detachably connected to the other end of the docking box 2. A right connecting ring 25 is installed on the top of the right support frame 24. Fixing rings 23 that match the left connecting ring 22 and the right connecting ring 25 are installed at both ends of the brush roller 1. A connecting frame 3 is installed on the brush handle 11. A connecting rod 31 is installed at the center of the connecting frame 3. One end of the connecting rod 31 is engaged with the bottom end of the docking box 2. A sliding plate 4 is slidably connected to the inner wall of the docking box 2. A sealing plate 41 is slidably connected to one end of the docking box 2.
[0019] In this implementation scheme: the brush roller 1 rotates on the brush handle 11. The fixing rings 23 installed at both ends of the brush roller 1 support the left connecting ring 22 and the right connecting ring 25. The left connecting ring 22 and the right connecting ring 25 respectively support the left support frame 21 and the right connecting ring 25, thus supporting the brush roller 1 at both ends. During use, when the left connecting ring 22 engages with the fixing ring 23, one end of the docking box 2 aligns with the bottom of the right support frame 24. At this time, the right support frame 24 can be fixedly connected to one end of the docking box 2, fixing the distance between the left support frame 21 and the right support frame 24, and ensuring the connection between the left connecting ring 22 and the right connecting ring 25... The connecting box 2 is securely supported at both ends of the brush roller 1, allowing it to be installed below the brush roller 1. The connection between the left connecting ring 22 and the right connecting ring 25 and the fixing ring 23 allows the connecting box 2 to revolve around the brush roller 1. When the brush roller 1 is painting walls or roofs, it is supported by its outer wall. The weight of the connecting box 2 below the brush roller 1 ensures it remains vertically aligned with the brush roller 1, preventing paint from falling directly onto workers, especially during roof painting. When refilling the paint on brush roller 1, the docking box 2 can be pushed to rotate it above brush roller 1, preventing it from interfering with placing brush roller 1 into the paint bucket for refilling. After refilling, the docking box 2, under its own weight, can continuously catch any residual paint that falls onto brush roller 1. When the docking box 2 is not needed, it can be rotated to a position corresponding to the connecting frame 3, and then threaded onto the connecting frame 3 via the connecting rod 31. The rotation of the connecting rod 31 allows adjustment of its position on the connecting frame 3, enabling the connecting rod 31 to... One end of the docking box 2 is supported and limited to keep the docking box 2 and the brush handle 11 in a horizontally corresponding position. This ensures that the use of the brush roller 1 is not affected and facilitates quick switching of the docking box 2's position. The docking box 2 can be separated from one end by the right support frame 24, allowing the left connecting ring 22, the left support frame 21, and the docking box 2 to be separated from the brush roller 1. This allows the docking box 2 to be removed. After removal, during cleaning, the sliding plate 4 can slide the sealing plate 41 outward, making it easier to scrape and remove the paint residue on the inner wall. This also makes it easier to clean the paint residue inside the docking box 2, thus ensuring the device can be used for a long time.
[0020] The left connecting ring 22 and the right connecting ring 25 are slidably connected to the fixed ring 23. A connecting plate 241 is installed on one side of the right support frame 24. The connecting plate 241 is connected to one end of the docking box 2 by a pin. The left connecting ring 22 and the right connecting ring 25 are slidably connected to the fixed ring 23, so that the left connecting ring 22 and the right connecting ring 25 can be supported on the fixed ring 23, while the left connecting ring 22 can be separated from the fixed ring 23, so that the docking box 2 can be separated. The connecting plate 241 is used to connect and support one end of the docking box 2 after the right support frame 24 is connected to one end of the docking box 2 by a pin, so that the right support frame 24 can be connected and supported on one end of the docking box 2.
[0021] A locking rod 242 is installed at one end of the docking box 2. The locking rod 242 is slidably connected to the bottom of the right support frame 24. When the docking box 2 is connected to the right support frame 24, the locking rod 242 is supported at the bottom of the right support frame 24, so that the docking box 2 can be stably supported between the left support frame 21 and the right support frame 24.
[0022] The sealing plate 41 has mounting blocks 42 at both ends that engage with one end of the docking box 2. A sliding rod 43 is slidably connected to one side of the mounting block 42, and a spring 431 is installed at one end of the sliding rod 43. The mounting blocks 42 at both ends of the sealing plate 41 can be connected and supported at one end of the docking box 2. The sliding rod 43, which is fixedly connected to one side of the mounting block 42, can be elastically pulled by the spring 431, so that the sealing plate 41 can be supported at one end of the docking box 2, sealing one end of the docking box 2. At the same time, it can provide an outward pushing force to the sealing plate 41, so that the sealing plate 41 can overcome the elastic tension of the spring 431, and the paint residue scraped by the slide plate 4 can be discharged from one end of the docking box 2.
[0023] A limiting groove 44 is provided at the connection between the docking box 2 and the slide plate 4. A limiting rod 441 is installed on the inner wall of the limiting groove 44. Push plates 442 are installed at both ends of the slide plate 4. The push plates 442 are slidably connected to the limiting rod 441. The limiting groove 44 is used to connect and limit the push plates 442 installed at both ends of the slide plate 4. Through the slidable connection between the limiting rod 441 and the push plate 442, the slide plate 4 can slide stably and horizontally on the inner wall of the docking box 2. At the same time, the push plates 442 can be easily pushed by the user, thereby driving the slide plate 4 to move.
[0024] One end of the connecting rod 31 is rotatably connected to a ferrule 321, and the bottom of the docking box 2 is provided with a locking post that matches the ferrule 321. When the bottom of the docking box 2 is rotated to a position corresponding to the connecting rod 31, the ferrule 321 can be supported on the locking post installed at the bottom of the docking box 2 under the displacement of the connecting frame 3, thereby allowing the docking box 2 to be supported and its position limited.
[0025] One end of the connecting rod 31 is threaded to the center of the connecting frame 3. A retaining plate 32 is installed on the outer wall of the retaining sleeve 321. One end of the retaining plate 32 engages with the brush handle 11. One end of the connecting rod 31 is threaded to the center of the connecting frame 3, so that the connecting rod 31 can rotate to adjust the position of the retaining sleeve 321, so that the retaining sleeve 321 can be connected to the retaining post installed at the bottom of the docking box 2 for support. The retaining sleeve 321 rotates at one end of the connecting rod 31, so that the retaining plate 32 can engage with the brush handle 11, so that it provides auxiliary support for the position of the retaining sleeve 321, while avoiding limiting the rotation of the connecting rod 31.
[0026] The working principle and usage process of this utility model are as follows: The right support frame 24 is connected to one end of the docking box 2 via a pin. At this time, the left connecting ring 22 and the right connecting ring 25 are slidably connected to the fixing rings 23 at both ends of the brush roller 1, allowing the docking box 2 to be installed below the brush roller 1. The connecting frame 3 is installed on the brush handle 11. Its position is adjusted by rotating the connecting rod 31, so that the retaining sleeve 321 at one end of the connecting rod 31 corresponds to the retaining post at the bottom of the docking box 2. Holding the brush handle 11, the roller brush 1 is dipped in paint and used to paint the wall or roof. During the painting process, the docking box 2 will remain vertically aligned with the roller brush 1 under the action of gravity. Correspondingly, to catch any dripping paint, if docking box 2 is not used temporarily, rotate docking box 2 to the position corresponding to connecting frame 3, adjust connecting rod 31 so that clamp 321 is supported on clamp post at the bottom of docking box 2, keep docking box 2 and brush handle 11 horizontally fixed, reduce space occupation and facilitate storage. When the device needs to be cleaned, first remove docking box 2 from roller brush 1, then slide slide plate 4 to scrape paint off the inner wall of docking box 2, then slide sealing plate 41 outward to discharge the scraped paint residue from one end of docking box 2, and finally wash and dry each part to complete the cleaning.
