[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4The utility model provides a technical solution: a multi-purpose wall painting brush for construction, comprising a mounting rod 1, a roller brush barrel 2, a flat bottom brush 6 and a row of brushes 11, one end of the roller brush barrel 2 is connected to a mounting seat 3 and is movably mounted in a groove at the top end of the mounting rod 1, a bolt 14 is provided at the connecting end of the mounting seat 3 and the mounting rod 1, a movable rod 4 is slidably connected inside the mounting rod 1, and a flat bottom brush 6 is movably mounted on one end of the movable rod 4, and the movable rod 4 is threadedly connected to one end of the row of brushes 11.

[0020] A positioning seat 5 is provided at one end of the movable rod 4, and the positioning seat 5 is connected to the flat brush 6 by a bolt 14. The flat brush 6 and the roller brush 2 are respectively connected to one end of the mounting rod 1 and the movable rod 4 through the positioning seat 5 and the mounting seat 3, and are fixed with bolts 14 for easy disassembly and replacement.

[0021] A guide groove 7 is provided inside the movable rod 4, and limit holes 8 are distributed at equal intervals inside the guide groove 7. The guide groove 7 provided inside the movable rod 4 is convenient for positioning and installation, and the limit holes 8 distributed inside the guide groove 7 are plugged into the limit pin 16, so that the extension length of the installation rod 1 and the movable rod 4 can be adjusted according to actual needs.

[0022] A slide groove 12 is provided inside the mounting rod 1, and a guide rail 13 is provided on the inner surface of the slide groove 12. The slide groove 12 is movably connected with the movable rod 4, and the guide rail 13 is slidably matched with the guide groove 7. The slide groove 12 moves along the guide rail 13, so that the movable rod 4 can be extended and retracted inside the slide groove 12, which can guide the movement of the mounting rod 1 and the movable rod 4, thereby increasing the stability and accuracy of the adjustment.

[0023] The mounting rod 1 is internally movably connected to a limit pin 16, one end of which passes through the guide rail 13 and is movably connected to the limit hole 8. The limit hole 8 is a conical structure. The shape and structure of the limit hole 8 facilitates the limit pin 16 to slide into the limit hole 8, and can play the function of automatic correction within a certain range, so that the movable rod 4 and the mounting rod 1 can be reset when there is a spacing deviation.

[0024] A handle 9 is provided at one end of the limit pin 16 , and tension springs 15 are symmetrically distributed between the handle 9 and the mounting rod 1 . The handle 9 is easily reset by the tension spring 15 , which not only improves the controllability, but also facilitates the connection between the limit pin 16 and the limit hole 8 .

[0025] Rubber sleeves 10 are respectively provided on the outer surfaces of the mounting rod 1 and the movable rod 4. The rubber sleeves 10 can increase the surface friction of the mounting rod 1 and the movable rod 4 and reduce the difficulty of painting operation.

[0026] Working principle: When using the multi-purpose wall painting brush for construction, when painting a large area, the flat-bottomed brush 6 and the roller brush barrel 2 can be used with both heads. The roller brush barrel 2 is more labor-saving, and the flat-bottomed brush 6 can be used to paint corners or places with edges. When it is necessary to repair small area defects, the movable rod 4 can be pulled out from the inside of the mounting rod 1, and the row brush 11 can be used for painting, and the row brush 11 can also be removed from the inside of the movable rod 4 and used alone. When the length needs to be adjusted, pull the handle 9 to retract the limit pin 16 into the hole inside the guide rail 13, and then the slide groove 12 of the movable rod 4 telescopically moves along the guide rail 13 inside the slide groove 12. When the length is appropriate, release the handle 9 and the tension spring 15 will reset the limit pin 16 and insert it into the limit hole 8. This not only increases the diversity of the overall use, but also the assembled structure is not easy to lose, and the area occupied by the tool is reduced, thereby increasing the overall practicality.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
