Abstract
Description
Technical Field
[0001] This application relates to the field of interior decoration technology, and in particular to an interior decoration painting device. Background Technology
[0002] Existing interior decoration painting devices typically include a paint roller and a handle. During use, the paint roller picks up paint for painting. However, existing devices tend to pick up too much paint on the roller. When the roller carries too much paint, dripping can easily occur during painting, wasting paint and potentially staining walls or floors, affecting the painting effect and work efficiency. Therefore, an interior decoration painting device is proposed. Utility Model Content
[0003] To address the problem of paint rollers easily picking up too much paint when dipping, this application provides an interior decoration painting device.
[0004] The interior decoration painting device provided in this application adopts the following technical solution:
[0005] An interior decoration painting device includes a pole body, which is L-shaped. A fixed sleeve is fixedly connected to the bottom of the vertical part of the pole body. A rotating shaft is rotatably connected inside the fixed sleeve. A brush roller is fixedly connected to the surface of the rotating shaft. The brush roller is parallel to the horizontal part of the pole body. A scraper ring is connected to the horizontal part of the pole body through a moving mechanism. The moving mechanism can drive the scraper ring to move back and forth on the surface of the brush roller. The control end of the moving mechanism is located at the top of the vertical part of the pole body.
[0006] Preferably, the moving mechanism includes a groove formed in the horizontal part of the rod, a slider is slidably installed inside the groove, the slider is fixedly connected to the scraper ring, a pull rope is fixedly connected to the surface of the slider, one end of the pull rope passes through the inner wall of the rod to the top of the rod and is fixedly connected to a pull block, and a spring is fixedly connected between the slider and the inner surface of the groove.
[0007] Preferably, the spring is compressed when the slider moves along the groove toward the vertical part of the rod.
[0008] Preferably, the scraper ring is coaxially arranged with the brush roller and the rotating shaft.
[0009] Preferably, the outer diameter of the scraper ring is smaller than the outer diameter of the sponge on the brush roller surface when it is not compressed.
[0010] In summary, this application includes the following beneficial technical effects:
[0011] In the decoration process, the user holds the upper vertical part of the rod and puts the brush roller into the paint bucket so that the paint submerges the brush roller. After the brush roller is dipped in paint, it is moved above the mouth of the paint bucket, and the moving mechanism drives the scraper ring to move back and forth on the surface of the brush roller. The scraper ring can squeeze the brush roller to prevent the brush roller from being dipped in too much paint and causing dripping and waste. Attached Figure Description

[0016] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0017] This application discloses an indoor decoration painting device, including a rod 1, which is L-shaped. A fixed sleeve 2 is fixedly connected to the bottom of the vertical part of the rod 1. A rotating shaft 3 is rotatably connected inside the fixed sleeve 2. A brush roller 4 is fixedly connected to the surface of the rotating shaft 3. The brush roller 4 is parallel to the horizontal part of the rod 1. A scraper ring 5 is connected to the horizontal part of the rod 1 through a moving mechanism. The moving mechanism can drive the scraper ring 5 to move back and forth on the surface of the brush roller 4. The control end of the moving mechanism is located at the top of the vertical part of the rod 1.
[0018] In this embodiment, during the decoration process, the user holds the upper part of the vertical part of the rod 1 and puts the brush roller 4 into the paint bucket so that the paint submerges the brush roller 4. After the brush roller 4 is dipped in paint, the brush roller 4 is moved above the mouth of the paint bucket, and the moving mechanism drives the scraper ring 5 to move back and forth on the surface of the brush roller 4. The scraper ring 5 can squeeze the brush roller 4 to prevent the brush roller 4 from being dipped in too much paint and causing dripping and waste.
[0019] Furthermore, the moving mechanism includes a groove 6 opened in the horizontal part of the rod 1, a slider 9 is slidably installed inside the groove 6, the slider 9 is fixedly connected to the scraper ring 5, a pull rope 7 is fixedly connected to the surface of the slider 9, one end of the pull rope 7 passes through the inner wall of the rod 1 to the top of the rod 1 and is fixedly connected to a pull block 8, and a spring 10 is fixedly connected between the slider 9 and the inner surface of the groove 6.
[0020] Furthermore, when the slider 9 moves along the groove 6 toward the vertical part of the rod 1, the spring 10 is compressed.
[0021] Furthermore, the scraper ring 5 is coaxially arranged with the brush roller 4 and the rotating shaft 3.
[0022] Furthermore, the outer diameter of the scraper ring 5 is smaller than the outer diameter of the sponge on the surface of the brush roller 4 when it is not compressed. When the brush roller 4 is brushing the wall, it can prevent the scraper ring 5 from contacting the wall and causing scratches on the wall.
[0023] In this embodiment, after the brush roller 4 is dipped in paint, the user moves the pull block 8, which drives the slider 9 and the scraper ring 5 to move towards the vertical part of the rod 1. At this time, the scraper ring 5 can squeeze the brush roller 4, and the spring 10 is compressed. After the user releases the pull block 8, the compressed spring 10 returns to its original position, which drives the slider 9 and the scraper ring 5 to return to their original position, so that the scraper ring 5 is stably located on the other side of the brush roller 4.
