Technical Field

[0001] The utility model relates to the technical field of roller brushes, in particular to a roller brush for decoration and renovation. Background Art

[0002] When decorating a house, it is generally necessary to treat the wall surface, and most of the existing treatment methods choose to paint. When painting, a roller brush is needed. The roller brush is a commonly used tool in decoration and renovation projects. The paint is applied to the wall by the roller, which is not only more labor-saving but also more efficient than a direct brush. Therefore, roller brushes are generally used for painting in house decoration. However, the handles of existing rollers are relatively short. When decorators deal with high walls, they need to stand on scaffolding or stools to operate, which is inconvenient to operate and has great safety hazards.

[0003] The utility model patent with application number CN202123108629.2 discloses a roller brush for decoration, including a sleeve, a fixed body is arranged at one end of the sleeve, a rotating column is arranged on the fixed body, a roller is arranged between the rotating columns, a slide groove is arranged in the sleeve, a slide rod is arranged in the slide groove, a fixed block is arranged at the end of the slide rod away from the sleeve, a plurality of sockets are arranged on the slide rod, a movable groove is arranged on the sleeve, and an insert block is arranged in the movable groove; the roller brush slides in the sleeve by arranging the slide rod to perform telescopic adjustment to adapt to The painting requirements of walls of different heights are met, and the sliding rod is fixed after extension by plugging the plug block into the socket to prevent the sleeve from falling back during painting, so as to achieve the effect of extension and contraction adjustment. However, when the roller brush is extended and adjusted, the sliding rod is limited by the position of the socket through the plug block plugged into the socket. In addition, when in use, the protrusion of the plug block may not only affect the grip, but the sliding connection with the moving groove is also easy to fall off during actual use, resulting in failure of the limit. Therefore, there is room for improvement. Utility Model Content

The outer diameters of the sliding sleeve 2 and the sliding limiting sleeve 8 correspond to the inner diameter of the outer sleeve 1. By arranging the limiting structure inside the outer sleeve 1, the overall surface of the rod body can be smooth and flat, avoiding the situation that the protrusion of the plug block may affect the grip;

[0028] The sliding limit sleeve 8 is provided with a limit hole 10 at the center of one end close to the roller connecting seat 3, and the shape of the limit hole 10 corresponds to the shape of the limit column 6. The end of the limit column 6 away from the roller connecting seat 3 passes through the limit hole 10 and is fixedly connected to the limit cap 9. The outer diameter of the limit cap 9 corresponds to the inner diameter of the threaded end 7. The limit column 6 cooperates with the limit hole 10 and the limit cap 9. When the threaded end 7 is tightened, the sliding limit sleeve 8 can be rotationally limited by the cooperation between the limit column 6 and the limit hole 10, and the limit cap 9 can prevent the sliding limit sleeve 8 from being completely disengaged from the outer sleeve 1 when the sliding limit sleeve 8 is loose, thereby enhancing the practicality of the device.

[0029] The sleeve wall of the sliding limit sleeve 8 is equidistantly provided with four convex grooves 11, and the sliding limit sleeve 8 is provided with a protrusion 12 on the sleeve wall in the middle of the inner side of the four convex grooves 11. The inner wall of the sliding limit sleeve 8 is provided with an internal thread 13, and the end of the threaded end 7 away from the sliding sleeve 2 is threadedly connected to the sliding limit sleeve 8 through the internal thread 13, and the thread height of the internal thread 13 corresponds to the height of the protrusion 12 of the sliding limit sleeve 8.
