DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model.

[0019] Please refer to Figures 1-5 The utility model provides a kind of technical scheme: a wall painting roller brush, including hand pole 1 and roller 2, roller 2 rotation is set on the surface of hand pole 1.

[0020] ​Furthermore: To facilitate the disassembly and assembly of the roller brush cylinder 3 and to enable the device to be used repeatedly, the roller 2 is provided with a roller brush cylinder 3 on its surface. Several guide rails 4 are fixedly connected around the surface of the roller 2 at equal intervals. Several guide grooves 5 that are used in conjunction with the guide rails 4 are opened around the inner wall of the roller brush cylinder 3 at equal intervals. A threaded short rod 6 is fixedly connected to one side of the roller 2, and one end of the threaded short rod 6 extends to the outside of the roller brush cylinder 3. A through groove 7 that is used in conjunction with the threaded short rod 6 is opened on one side of the roller brush cylinder 3. A nut 8 is threadedly connected to the surface of the threaded short rod 6 and located on one side of the roller brush cylinder 3. A receiving groove 9 that communicates with the through groove 7 is opened on one side of the roller brush cylinder 3. An external threaded cover cap 14 is threadedly connected to the inside of the receiving groove 9.

[0021] Furthermore: To facilitate the adjustment of the device's height, the bottom of the handheld lever 1 is provided with an internal threaded groove 10 that penetrates the interior. The internal threaded groove 10 is connected to a threaded long rod 11, and the bottom of the threaded long rod 11 is fixedly connected to a handle 12. The surface of the handheld lever 1 is fixedly connected to a protective sleeve 13 that matches the threaded long rod 11. The surface of the handle 12 is fixedly connected with several rubber resistance-increasing protrusions 15 at equal intervals.

[0022] When assembling and using: the roller brush cylinder 3 is slidably installed on the surface of the roller 2 by the guide rail 4 and the guide groove 5. After the roller brush cylinder 3 slides into place, the threaded short rod 6 on the side of the roller 2 will pass through the through groove 7 on the side of the roller brush cylinder 3. Then, the nut 8 is threaded onto the surface of the threaded short rod 6 to fix the roller 2 and the roller brush cylinder 3. Then, the external thread cover cap 14 is screwed into the inside of the storage groove 9 to cover the threaded part of the threaded short rod 6 and the nut 8.
