Technical Field

[0001] This utility model relates to a brush for scraping off excess paint, and more particularly to a brush for scraping off excess paint, belonging to the field of home decoration and renovation technology. Background Technology

[0002] Scraping off excess color refers to a renovation process that uses special brushes to physically polish smooth surfaces such as painted surfaces and stone, removing the old, aged, or faded paint / coating layer to reveal the bright, complete original color of the underlying material. It can quickly restore the material's true color without damaging the substrate.

[0003] Most of the paint scraping brushes on the market are only compatible with one model or a single bristle hardness. However, when faced with substrate surfaces of different smoothness, it is often difficult to meet the diverse construction needs with just one brush. In order to achieve the ideal painting effect, the painters have to carry multiple brushes with different hardnesses, which not only increases the burden of tools, but also affects the convenience and efficiency of construction.

[0004] Therefore, there is an urgent need to improve a brush for scraping off excess color in order to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a brush for scraping off excess color. One brush can have bristles of various hardness, allowing construction workers to adapt to substrate surfaces with different flatness by carrying only one brush.

[0006] To achieve the above objectives, the main technical solution adopted by this utility model includes: a brush for scraping off excess color, comprising a shell, wherein at least three placement boxes are provided inside the shell, each placement box is rotatably provided with a rotating shaft, each rotating shaft is respectively fixedly installed with a first brush bristle, a second brush bristle and a silicone strip, each placement box is rotatably installed with a connecting rod at both ends, wherein a driven wheel is fixedly installed on one side of the connecting rod, each driven wheel is meshed with a driving wheel, and a connecting plate is fixedly installed on one side of the connecting rod.

[0007] Preferably, a device box is fixedly installed on one side of the outer shell, the outer shell is in communication with the device box, and the driving wheel, the driven wheel and the connecting plate are all located inside the device box.

[0008] Preferably, a disc is fixedly installed inside the outer casing, and the disc is rotatably connected to the connecting rod on the other side.

[0009] Preferably, the placement box has corresponding grooves on both sides inside, and a slider is slidably connected in the groove, and the slider is rotatably connected to the rotating shaft.

[0010] Preferably, a first spring is fixedly installed on one side of the slider, and the end of the first spring away from the slider is fixedly connected to the inner wall of the placement box.

[0011] Preferably, a hole is provided on one side of the device box, and a second spring is fixedly installed in the hole, with a positioning bead fixedly installed at one end of the second spring.

[0012] Preferably, a rotating rod is fixedly installed on the drive wheel, the rotating rod extends to the outside of the device box, a handle is fixedly installed at one end of the rotating rod, a turntable is fixedly installed on the rotating rod, and at least three circular grooves are opened on one side of the turntable, and the positioning bead is slidably connected to the circular groove.

[0013] This utility model has at least the following beneficial effects: 1. When the drive wheel rotates, it drives the three driven wheels that are meshed with it to rotate. At the same time, each of the three driven wheels is fixedly installed with a connecting rod, and the connecting rod near the driven wheel is fixedly connected to the connecting plate. This causes the three driven wheels to rotate with the placement box connected to them, so that each placement box will rotate to the bottom and contact the reference surface that needs to be scraped to remove the floating color. The operator can rotate the drive wheel to switch between different types of brushes, so as to adapt to different substrate surfaces and clean the floating color on them.

[0014] 2. The elastic force of the first spring can drive the slider to slide stably in the groove, thereby making the rotating shaft follow the movement of the slider. Then, the bristles on the rotating shaft can be closely attached to the reference surface by the elastic force of the first spring, so as to better scrape off the floating color on the reference surface.

[0017] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0018] Examples, such as Figures 1-5 As shown, a brush for scraping off excess color includes a housing 1. Inside the housing 1 are at least three placement boxes 8. Each placement box 8 has a rotating shaft 11 rotatably mounted. Each rotating shaft 11 is fixedly mounted with a first brush bristle 12, a second brush bristle 121, and a silicone strip 122. Connecting rods 7 are rotatably mounted at both ends of each placement box 8. A driven wheel 6 is fixedly mounted on one side of each connecting rod 7. Each driven wheel 6 is meshed with a driving wheel 5. A connecting plate 14 is fixedly mounted on one side of each connecting rod 7. When the driving wheel 5 rotates, it drives the three driven wheels 6 meshing with it to rotate. Simultaneously, each of the three driven wheels 6 is fixedly mounted with a connecting rod 7, and the connecting rod 7 closest to the driven wheel 6 is fixedly connected to the connecting plate 14. This causes the three driven wheels 6 to pull the placement boxes connected to them. The device revolves around a central axis, causing each placement box 8 to rotate to its lowest point and contact the reference surface where the surface color needs to be scraped. Each placement box 8 contains a rotating shaft 11, which is fixedly equipped with a first brush bristle 12, a second brush bristle 121, and a silicone strip 122. The first brush bristle 12 is made of elastic nylon bristles, soft and suitable for smooth substrates such as boards and metal surfaces. The second brush bristle 121 is made of a mixture of hard pig bristles and carbon fiber, hard and suitable for rough substrates such as cement walls and brickwork. The silicone strip 122 is a silicone scraper strip without bristles, suitable for edges, corners, and curved surfaces such as furniture edges and pipe walls. Operators can switch between different brush materials by rotating the drive wheel 5, allowing for the cleaning of surface color on different substrates.

[0019] like Figures 2-3As shown, further, a device box 2 is fixedly installed on one side of the outer shell 1, and the outer shell 1 is connected to the device box 2. The driving wheel 5, the driven wheel 6, and the connecting plate 14 are all located inside the device box 2. A disc 13 is fixedly installed inside the outer shell 1, and the disc 13 is rotatably connected to the connecting rod 7 on the other side. By setting the driving wheel 5, the driven wheel 6, and the connecting plate 14 to be located inside the device box 2, the safety of the rotating structure is ensured, and the operator will not be injured. At the same time, the connecting rod 7 fixedly installed at the other end of the placement box 8 is rotatably connected to the disc 13, ensuring the stability of the placement box 8 when it is driven to rotate.

[0020] like Figure 4 As shown, further, the inner sides of the placement box 8 are provided with corresponding grooves 801. A slider 9 is slidably connected in the groove 801. The slider 9 is rotatably connected to the rotating shaft 11. A first spring 10 is fixedly installed on one side of the slider 9. The end of the first spring 10 away from the slider 9 is fixedly connected to the inner wall of the placement box 8. By setting the slider 9 to slide in the groove 801, and the first spring 10 fixedly installed between the slider 9 and the inner wall of the placement box 8, the slider 9 can be driven to slide stably in the groove 801 by the elastic force of the first spring 10. This causes the rotating shaft 11 to follow the movement of the slider 9. Then, the bristles on the rotating shaft 11 can be tightly attached to the reference surface by the elastic force of the first spring 10, so as to better scrape off the floating color on the reference surface.

[0021] like Figure 1 as well as Figure 5 As shown, further, a hole 15 is provided on one side of the device box 2, and a second spring 16 is fixedly installed in the hole 15. A positioning bead 17 is fixedly installed at one end of the second spring 16. A rotating rod 301 is fixedly installed on the drive wheel 5, and the rotating rod 301 extends to the outside of the device box 2. A handle 3 is fixedly installed at one end of the rotating rod 301, and a turntable 4 is fixedly installed on the rotating rod 301. At least three circular grooves 401 are provided on one side of the turntable 4. The positioning bead 17 is slidably connected to the circular grooves 401. By setting the rotating rod 301 to be fixedly connected to the drive wheel 5 and the handle 3, when the operator turns the handle 3, it will drive the rotating rod 301 and the drive wheel 5. Wheel 5 rotates, and simultaneously, rotating rod 301 and turntable 4 rotate. When the circular groove 401 on turntable 4 rotates to the position of positioning bead 17, the elastic force of the second spring 16 pushes the positioning bead 17 into the circular groove 401, thereby limiting the rotation position of the circular groove 401. When the positioning bead 17 is inserted into the circular groove 401, there will be a clicking sound, which can remind the user that a set of brushes is at the bottom. At the same time, the position of the circular groove 401 corresponds to the position of three sets of brushes. When the operator continues to rotate handle 3, the turntable 4 will squeeze the positioning bead 17. At this time, the second spring 16 is in a squeezed state, which allows the turntable 4 to continue to rotate.

[0022] In this embodiment, as Figures 1-5As shown in this embodiment, the principle of a brush for scraping off excess color is as follows: When the operator turns handle 3, it drives the rotating rod 301 and the drive wheel 5 to rotate. Simultaneously, the rotating rod 301 and the turntable 4 rotate. When the circular groove 401 on the turntable 4 rotates to the position of the positioning bead 17, the second spring 16 pushes the positioning bead 17 into the circular groove 401, thus limiting the rotational position of the circular groove 401. When the drive wheel 5 rotates, it drives the three driven wheels 6 meshing with it to rotate. Each of the three driven wheels 6 is fixedly equipped with a connecting rod 7, and the connecting rod 7 is located near the driven wheel 6. The connecting rod 7 is fixedly connected to the connecting plate 14, which causes the three driven wheels 6 to rotate with the placement boxes 8 connected to them. This causes each placement box 8 to rotate to the bottom and contact the reference surface where the excess color needs to be scraped off. Through the elastic force of the first spring 10, the slider 9 can be driven to slide stably in the slide groove 801, which causes the rotating shaft 11 to follow the movement of the slider 9. Then, the bristles on the rotating shaft 11 can be tightly attached to the reference surface through the elastic force of the first spring 10, so as to better scrape off the excess color from the reference surface.
