Description

Technical Field

[0001] The utility model relates to the technical field of decoration tools, in particular to a painting device for decoration. Background Art

[0002] The most commonly used painting device for decoration is the roller brush. Roller brushes are mostly made of wool and foam plastic. They can be divided into paint roller brushes, napped roller brushes, floor paint roller brushes, flat paint roller brushes, etc. They are mainly used for rolling paint in building decoration projects.

[0003] However, the existing decoration painting device can only fix rollers of a certain length, but cannot fix rollers of different lengths, resulting in the inability to adapt to different painting environments. For example, a longer roller is suitable for painting a large area, which can improve work efficiency, and a shorter roller is suitable for a narrow space, which is convenient and flexible to use. In addition, the handheld part of the painting device is long, which is inconvenient to carry.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the original decoration painting device. Utility Model Content

DETAILED DESCRIPTION

[0023] 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.

[0024] See also Figure 1-6 The utility model provides a technical solution: a decoration painting device, comprising a fixing plate 1, a roller 3 is fixed to the fixing plate 1 through a fixing part 2, and a brush 4 is fixed to the outer wall of the roller 3;

[0025] A hand-held portion 7 is provided at the bottom of the fixed plate 1;

[0026] The fixing part 2 includes a through slot 21, a through slot 21 is provided inside the fixing plate 1, a fixing block 22 is fixed inside the through slot 21, a first rotating shaft 23 is rotatably installed between the fixing blocks 22 through a bearing, a movable plate 24 is nested and installed at the end of the first rotating shaft 23, the movable plate 24 is located inside the through slot 21, a side plate 25 is fixed inside the end of the movable plate 24 that passes through the through slot 21, a docking column 26 is fixed at the top of one side of the side plate 25, the end of the docking column 26 is located inside the docking groove 27, and the docking groove 27 is provided at the end of the drum 3, the outer wall of the first rotating shaft 23 is located between the fixing blocks 22, a first bevel gear 28 is fixed thereto, a second bevel gear 29 is meshed at the top of one side of the first bevel gear 28, a second rotating shaft 210 is fixed at the top of the second bevel gear 29, The upper end of the second rotating shaft 210 passes through the top of the fixed plate 1 and is fixed with a handle 211. The outer wall of the second rotating shaft 210 is rotatably connected to the inner wall of the fixed plate 1 through a bearing. The thread directions of the two ends of the first rotating shaft 23 are designed to be opposite, and the first rotating shaft 23 is threadedly connected to the movable plate 24, and the movable plate 24 and the through groove 21 form a snap-fit ​​sliding structure, and there are two movable plates 24, side plates 25, docking columns 26 and docking grooves 27 symmetrically distributed about the central axis of the fixed plate 1, ensuring that when the handle 211 is rotated forward or reversed, the two docking columns 26 and the two docking grooves 27 can move away from each other or move towards each other, so that rollers 3 of different lengths can be fixed, the adaptability of the painting device is improved, and the quick disassembly and installation of the roller 3 are convenient.

[0027] An anti-slip groove 5 is provided at the top of the through groove 21, and an anti-slip block 6 is fixed to one side of the top of the movable plate 24 close to the fixed block 22. The end of the anti-slip block 6 is slidably installed inside the anti-slip groove 5. The design of the anti-slip groove 5 and the anti-slip block 6 prevents the movable plate 24 from separating from the through groove 21.

[0028] The outer wall of the docking post 26 fits with the inner wall of the docking groove 27, and the docking post 26 and the docking groove 27 form a rotating structure, which ensures that the drum 3 can be fixed by the docking post 26 and the docking groove 27, and at the same time allows the drum 3 to rotate normally.

[0029] The hand-held portion 7 includes a first hand-held rod 71, and the first hand-held rod 71 is fixed at the center of the bottom of the fixed plate 1. A threaded groove 72 is provided at the bottom of the first hand-held rod 71, both sides of the first hand-held rod 71 and the end of the second hand-held rod 74. The internal thread of the threaded groove 72 is installed with a threaded rod 73, and the end of the threaded rod 73 is fixedly connected to the other end of the second hand-held rod 74. Six second hand-held rods 74 are provided, so that the first hand-held rod 71 and the second hand-held rods 74 can be disassembled, and the second hand-held rods 74 can be disassembled, thereby reducing the length of the painting device and facilitating the carrying of the painting device. At the same time, the disassembled second hand-held rod 74 can be installed on the first hand-held rod 71, so that the first hand-held rod 71 is perpendicular to the second hand-held rod 74, and the second hand-held rod 74 will not be forgotten or lost.

[0030] Working principle: When using the decoration painting device, when it is necessary to paint a large area of ​​wall, turn the handle 211 forward, and then the handle 211 drives the first rotating shaft 23 to rotate through the second rotating shaft 210, the second bevel gear 29 and the first bevel gear 28. Since the first rotating shaft 23 and the movable plate 24 are threadedly connected, and the movable plate 24 and the through groove 21 form a snap-fit ​​sliding structure, the two movable plates 24, the two side plates 25 and the two docking posts 26 move away from each other at the same time, and then the longer roller 3 is placed between the two side plates 25, and then the handle 211 is reversed. According to the same principle, the two docking posts 26 move towards each other until the two docking posts 26 are snapped with the two docking grooves 27, so that the longer roller 3 can be fixed, which is conducive to the painting device for painting a large area of ​​wall;

[0031] When it is necessary to paint the wall of a narrow space, the handle 211 is reversed so that the two docking posts 26 move closer to each other until the two docking posts 26 engage with the two docking grooves 27, thereby fixing the shorter roller 3, which is beneficial for the painting device to paint the wall of the narrow space;

[0032] By rotating the second holding rod 74, the second holding rod 74 drives the threaded rod 73 to rotate. Since the threaded rod 73 and the threaded groove 72 are threadedly connected, the second holding rod 74 is separated from the two sides of the first holding rod 71. The threaded rod 73 on the second holding rod 74 is threadedly connected to the threaded groove 72 at the bottom of the first holding rod 71. The two second holding rods 74 are fixed together by the threaded rod 73 and the threaded groove 72, thereby extending the length of the painting device so that the painting device can paint higher walls. The two second holding rods 74 can be disassembled by the threaded rod 73 and the threaded groove 72, thereby reducing the length of the painting device and making it easier to carry the painting device. The second holding rod 74 and the first holding rod 71 can be fixed together by the threaded rod 73 and the threaded groove 72, so that the first holding rod 71 is perpendicular to the second holding rod 74, and the second holding rod 74 will not be forgotten or lost.

[0033] Although detailed descriptions have been given, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
