[0020] Example 1: Please refer to Figure 1-Figure 6 The illustrated device for painting building walls comprises a hollow handle 1, a brush rod 2 fixedly connected to the hollow handle 1, and a roller brush 3 rotatably mounted on the brush rod 2, the outer wall of the brush rod 2 is fixedly connected to a shell 6, the inner wall of the shell 6 is fitted with a plug plate 9, a fixing mechanism is provided between the plug plate 9 and the shell 6, and the end of the plug plate 9 located on the outer side of the shell 6 is fixedly connected to a connecting plate 5, the upper end of the connecting plate 5 is fixedly connected to a triangular shell 4, the triangular shell 4 is located directly below the roller brush 3, a V-shaped groove 11 is provided at the upper end of the shell 6 corresponding to the triangular shell 4, the V-shaped groove 11 and the triangular shell 4 are slidably matched, an extension tube 15 is fitted to the inner wall of the hollow handle 1, and an adjustment mechanism and a guide component are respectively provided between the extension tube 15 and the hollow handle 1.

[0021] See also Figure 2-Figure 4 In the figure, the fixing mechanism includes two cylindrical grooves 13 and two arc grooves 12. The two cylindrical grooves 13 are respectively opened at the upper and lower ends of the plug plate 9, and the inner walls of the two cylindrical grooves 13 are fitted with plug posts 10. The ends of the two plug posts 10 that are away from each other are both hemispherical, and elastic parts are respectively provided between the two plug posts 10 and the two cylindrical grooves 13. The two arc grooves 12 are respectively opened on the inner wall of the shell 6 corresponding to the two plug posts 10, and the two arc grooves 12 are respectively fitted with the hemispherical ends of the two plug posts 10.

[0022] See also Figure 4 In the figure, the elastic member includes a spring 14, which is fixedly connected between the other end of the plug post 10 and the inner circular surface of the cylindrical groove 13.

[0023] In this embodiment, when the painting device is painting the ceiling, the paint dripping from the roller brush 3 will be collected in the triangular shell 4. When the triangular shell 4 needs to be removed from the painting device, the triangular shell 4 is directly pulled in the direction away from the shell 6, and the triangular shell 4 will slide in the V-shaped groove 11 on the shell 6 in the direction away from the shell 6 (it should be noted that when the triangular shell 4 is installed back on the device, the V-shaped groove 11 plays a positioning and guiding role, which facilitates the insertion of the plug plate 9 into the shell 6), and the triangular shell 4 will drive the connecting plate 5 to move in the direction away from the shell 6, and the connecting plate 5 will drive the plug plate 9 When sliding outward in the shell body 6, the two plug posts 10 on the plug plate 9 will move toward each other in the cylindrical grooves 13 on their respective corresponding plug plates 9 while moving outward (in this process, the springs 14 between the two cylindrical grooves 13 and the respective corresponding plug posts 10 will be squeezed), and the hemispherical ends of the two plug posts 10 will slide away from the arc grooves 12 in their respective corresponding shell bodies 6 until the plug plate 9 completely leaves the shell body 6, and the triangular shell 4 is removed from the painting device. Similarly, the triangular shell 4 can be installed back on the painting device by moving it in the opposite direction, and the disassembly and assembly operations are simple.

[0024] Example 2: Please refer to Figure 1 and Figure 5 This embodiment further explains Example 1. The adjustment mechanism shown in the figure includes a knob screw 7 and a plurality of screw holes 16. The knob screw 7 penetrates and is tightened on the inner wall of the hollow handle 1 near the lower edge. The plurality of screw holes 16 are arranged in a linear array from top to bottom on the outer wall of the extension tube 15. The screw hole 16 at the bottom is threadedly matched with the knob screw 7.

[0025] See also Figure 5 and Figure 6 In the figure, the guide assembly includes a guide block 17 and a guide groove 18. The guide block 17 is fixedly connected to the upper edge of the outer wall of the extension tube 15. The guide groove 18 is opened on the inner wall of the hollow handle 1 corresponding to the guide block 17, and the guide groove 18 and the guide block 17 are slidably matched.

[0026] See also Figure 1 and Figure 5 As shown in the figure, the bottom end of the extension tube 15 is fixedly connected with a pulling block 8, and the upper end of the pulling block 8 fits with the bottom end of the hollow handle 1.

[0027] In this embodiment, when the length of the hollow handle 1 does not meet the use requirements, the knob screw 7 can be rotated outward, the knob screw 7 will rotate outward in the inner wall of the hollow handle 1, and the knob screw 7 will rotate outward in a screw hole 16 located at the bottom on the corresponding extension tube 15, until the knob screw 7 is completely turned away from the screw hole 16, and the pulling block 8 is pulled downward, and the pulling block 8 will drive the extension tube 15 to slide downward in the inner wall of the hollow handle 1 (in this process, the guide block 17 on the extension tube 15 will slide downward in the guide groove 18 on the hollow handle 1) until the extension tube When 15 is moved to the required position, the knob screw 7 is turned inwardly, the knob screw 7 will rotate inwardly in the inner wall of the hollow handle 1, and the knob screw 7 will rotate inwardly in another screw hole 16 on the corresponding extension tube 15, until the knob screw 7 is tightened in the screw hole 16, and the extension tube 15 can be re-fixed on the hollow handle 1 after the movement, and the staff can hold the extension tube 15 to operate the painting device to perform the painting operation. Similarly, the extension tube 15 can be reset according to the opposite operation, thereby reducing the space occupied and facilitating the storage and transportation of the painting device.

[0028] It should be noted that when the present painting device is used to paint the ceiling walls, the paint dripping from the roller brush 3 will be collected in the triangular shell 4, which reduces the waste of paint and the possibility of the dripping paint causing harm to the health of the workers. The triangular shell 4 is easy to assemble and disassemble, and the gripping part of the present painting device is adjustable in length, and has good applicability.
