DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] Now, the present utility model will be further described in detail with reference to the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, only showing the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.
[0020] Refer to Figure 1 、 Figure 2 And Figure 4As shown in the figure, the present utility model provides a technical solution: a roller brush for painting, including a plastic grip 1. A connecting rod 2 is fixedly connected to the top of the plastic grip 1. A bearing 3 is fixedly connected to the surface of the connecting rod 2. A mounting plate 4 is fixedly connected to the outer wall of the bearing 3. Storage grooves 5 are provided at both the top and bottom of the mounting plate 4. A limiting block 6 is slidably connected to the inside of the storage groove 5. A roller brush 7 is slidably connected to the surface of the mounting plate 4. An installation groove 8 is provided at one end of the roller brush 7. The surface of the mounting plate 4 is slidably connected to the inside of the installation groove 8. Limiting grooves 9 are provided at both the top and bottom inside the installation groove 8. The surface of the limiting block 6 is slidably connected to the inside of the limiting groove 9. The user aligns the installation groove 8 at one end of the roller brush 7 with the position of the mounting plate 4 and inserts it. Then, move the limiting block 6 into the inside of the limiting groove 9 to fix the roller brush 7. During the process of painting with the roller brush 7, the mounting plate 4 is driven to rotate. By installing the bearing 3 on the surface of the connecting rod 2 and the inner wall of the mounting plate 4, the friction between the connecting rod 2 and the mounting plate 4 can be reduced, and the wear resistance effect can be increased. At the same time, the roller brush 7 can be disassembled and assembled, which can save the cost required to replace the entire tool.
[0021] Referring to Figure 4 As shown in the figure, in this implementation: A return spring 10 is fixedly connected to the bottom of the limiting groove 9. The bottom of the return spring 10 is fixedly connected to the bottom inside the storage groove 5. When the user installs the roller brush 7, by pressing the limiting block 6, the limiting block 6 is retracted into the inside of the storage groove 5. Align the limiting groove 9 with the position of the limiting block 6 and insert it. When the limiting groove 9 moves to the position of the limiting block 6, release the extrusion on the limiting block 6, and the return spring 10 pushes the limiting block 6 to move outward and enter the inside of the limiting groove 9 to fix the roller brush 7.
[0022] Referring to Figure 4 As shown in the figure, in this implementation: Limiting sliding grooves 11 are provided on both sides inside the storage groove 5. Limiting sliding blocks 12 are fixedly connected to both sides of the limiting block 6. One side of the limiting sliding groove 11 penetrates the surface of the mounting plate 4, and one end of the limiting sliding block 12 protrudes from one side of the mounting plate 4. When the user needs to disassemble the roller brush 7 for replacement, move the limiting sliding block 12 towards the middle to drive the limiting block 6 to retract into the inside of the storage groove 5, releasing the limitation on the roller brush 7, so that the roller brush 7 can be removed from the surface of the mounting plate 4 for replacement. At the same time, the limiting sliding block 12 limits the movement of the limiting block 6 to prevent the limiting block 6 from detaching from the inside of the storage groove 5 when the return spring 10 pushes the limiting block 6 upward.
[0023] Referring to Figure 4As shown in the figure, in this implementation: a placement groove 13 is opened at the bottom inside the limit chute 11, a thrust spring 14 is fixedly connected to the bottom inside the placement groove 13, the top of the thrust spring 14 is fixedly connected to a sealing plate 15. By installing the thrust spring 14 and the sealing plate 15 on one side of the plastic grip 1, when the user moves the limit slider 12 towards the middle, the sealing plate 15 is indented into the interior of the placement groove 13 under pressure. After installing the roller brush 7, the limit block 6 drives the limit slider 12 to move upward, releasing the extrusion on the sealing plate 15. Under the thrust of the thrust spring 14, the sealing plate 15 is pushed upward to fit against the bottom of the limit slider 12, closing the interior of the storage groove 5 to prevent paint from flowing into the interior of the storage groove 5 during painting, which may cause blockage of the limit block 6 due to long-term accumulation and prevent the roller brush 7 from being disassembled.
[0024] Refer to Figure 4 As shown in the figure, in this implementation: one side of the limit block 6 is beveled. When the user installs the roller brush 7, the roller brush 7 is inserted into the position of the mounting plate 4. When one side of the roller brush 7 contacts the beveled surface of the limit block 6, the roller brush 7 forms an extrusion on the limit block 6, causing the limit block 6 to be indented into the interior of the storage groove 5. When the limit groove 9 inside the roller brush 7 moves to the position of the limit block 6, the extrusion on the limit block 6 is released. Under the thrust of the return spring 10, the limit block 6 is pushed into the interior of the limit groove 9 to fix the roller brush 7.
[0025] Refer to Figure 3 As shown in the figure, in this implementation: a silica gel sleeve 16 is adhesively connected to the surface of the plastic grip 1. By installing the silica gel sleeve 16 on the surface of the plastic grip 1, it can prevent the plastic grip 1 from abrading the hand and causing the paint to infect the wound.
[0026] Refer to Figure 3 As shown in the figure, in this implementation: finger grooves 17 are opened on the surface of the silica gel sleeve 16. By opening the finger grooves 17 on the surface of the silica gel sleeve 16, the silica gel sleeve 16 can fit more closely to the hand, making it more comfortable during the painting process and relieving hand fatigue.
[0027] Working principle: The user inserts one end of the roller brush 7 with the mounting groove 8 aligned with the position of the mounting plate 4, and moves the limit block 6 into the interior of the limit groove 9 to fix the roller brush 7. During the process of using the roller brush 7 for painting, the mounting plate 4 is driven to rotate. By installing bearings 3 on the surface of the connecting rod 2 and the inner wall of the mounting plate 4, the friction between the connecting rod 2 and the mounting plate 4 can be reduced, and the wear resistance effect can be increased. At the same time, disassembling and assembling the roller brush 7 can save the cost required to replace the entire tool. When installing the roller brush 7, by pressing the limit block 6, the limit block 6 is retracted into the interior of the receiving groove 5, and the limit groove 9 is aligned with the position of the limit block 6 and inserted. When the limit groove 9 moves to the position of the limit block 6, the extrusion of the limit block 6 is released, and the return spring 10 pushes the limit block 6 to move outward and enter the interior of the limit groove 9 to fix the roller brush 7. When it is necessary to disassemble the roller brush 7 for replacement, move the limit slider 12 towards the middle to drive the limit block 6 to retract into the interior of the receiving groove 5, release the limit on the roller brush 7, so that the roller brush 7 can be removed from the surface of the mounting plate 4 for replacement. At the same time, the limit slider 12 limits the movement of the limit block 6 to prevent the limit block 6 from detaching from the interior of the receiving groove 5 when the return spring 10 pushes the limit block 6 upward. By installing a thrust spring 14 and a sealing plate 15 on one side of the plastic grip 1, when the user moves the limit slider 12 towards the middle, the sealing plate 15 is pressed and retracted into the interior of the placement groove 13. After the roller brush 7 is installed, the limit block 6 drives the limit slider 12 to move upward, releasing the extrusion on the sealing plate 15. Under the thrust of the thrust spring 14, the sealing plate 15 is pushed upward to fit with the bottom of the limit slider 12, closing the interior of the receiving groove 5 to prevent the paint from flowing into the interior of the receiving groove 5 during painting, resulting in long-term accumulation and blocking the limit block 6, causing the roller brush 7 to be unable to be disassembled. When installing the roller brush 7, insert the roller brush 7 into the position aligned with the mounting plate 4. When one side of the roller brush 7 contacts the inclined surface of the limit block 6, the roller brush 7 forms an extrusion on the limit block 6, causing the limit block 6 to retract into the interior of the receiving groove 5. When the limit groove 9 inside the roller brush 7 moves to the position of the limit block 6, the extrusion on the limit block 6 is released. Under the thrust of the return spring 10, the limit block 6 is pushed into the interior of the limit groove 9 to fix the roller brush 7. By installing a silica gel sleeve 16 on the surface of the plastic grip 1, it can prevent the plastic grip 1 from abrading the hand and causing the paint to infect the wound. By opening finger grooves 17 on the surface of the silica gel sleeve 16, the silica gel sleeve 16 can fit more closely with the hand, making it more comfortable during the painting process and relieving hand fatigue.
