[0031] 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.
[0032] The utility model provides a double-roller paint brush, such as Figure 1-Figure 4 As shown, the double-roller paint brush comprises a handheld frame 1, a first bracket 2 and a second bracket 3 arranged on the handheld frame 1, and a first roller brush body 21 and a second roller brush body 31 rotatably connected to one end of the first bracket 2 and the second bracket 3; the double-roller paint brush also includes a fixed column 4 fixedly connected to one end of the handheld frame 1, a connecting column 5 arranged at one end of the fixed column 4 and connected to the end of the first bracket 2 away from the first roller brush body 21, a fixed cylinder 6 fixedly installed on the side of the fixed column 4 connected away from the handheld frame 1, and a locking component 7 arranged in the fixed column 4 and the connecting column 5 for locking the fixed column 4 and the connecting column 5, and the end of the second bracket 3 away from the second roller brush body 31 is rotatably connected to the fixed cylinder 6; an adjusting component 61 for adjusting the rotation angle of the second bracket 3 is arranged in the fixed cylinder 6.
[0033] When in use, the first bracket 2 and the second bracket 3 can be arranged in a vertically symmetrical state, and then the fixing column 4 and the connecting column 5 are locked by the locking component 7, so that the first roller brush body 21 and the second roller brush body 31 can be simultaneously brushed up and down; secondly, the connection between the locking component 7 and the fixing column 4 and the connecting column 5 can be released, and the first bracket 2 can be disassembled, so that the second roller brush body 31 can be brushed alone; and the connection between the locking component 7 and the fixing column 4 and the connecting column 5 can be released, and the first bracket 2 can be rotated to a position relative to the second bracket 3, and then by adjusting the adjustment component 61, the first roller brush body 21 and the second roller brush body 31 can be arranged at different angles for brushing operations to meet the painting needs of different walls. Among them, when it is necessary to control the first roller brush body 21 and the second roller brush body 31 for brushing, the user only needs to hold the position of the handheld frame 1 by hand to operate the moving direction and speed of the handheld frame 1 to achieve uniform brushing.
[0034] Specifically, the adjustment assembly 61 includes a connecting shaft 611 rotatably connected in the fixed cylinder 6 and connected to the second bracket 3, a worm gear 612 fixedly sleeved on one end of the connecting shaft 611 away from the second bracket 3, and a worm 613 rotatably connected in the fixed cylinder 6 and meshing with the worm gear 612. Among them, one end of the worm 613 passes through the fixed cylinder 6 and is fixedly connected to the knob 614; when it is necessary to adjust the brushing angle of the second roller brush body 31, the user only needs to simply turn the knob 614. When the knob 614 rotates, the worm 613 will rotate accordingly. Since the worm 613 is meshed with the worm gear 612, the worm gear 612 will also rotate accordingly. Then, the rotation of the worm gear 612 will drive the connecting shaft 611 to rotate together, and the connecting shaft 611 is connected to the second bracket 3, so the rotation of the connecting shaft 611 will affect the position and angle of the second bracket 3. Therefore, by adjusting the number of rotations of the knob 614, the rotation angle of the second roller brush body 31 on the second bracket 3 can be easily changed, thereby realizing the adjustment of the position and posture of the double-roller paint brush to meet different brushing needs.
[0035] Furthermore, the locking assembly 7 includes a nut 72 fixedly installed in the connecting column 5 and an adjusting bolt 71 screwed on the nut 72 and passing through the connecting column 5 and the fixing column 4 in sequence, and the adjusting bolt 71 is rotatably connected to the fixing column 4 and the connecting column 5; the user only needs to simply rotate the adjusting bolt 71 so that the adjusting bolt 71 is fully inserted into the nut 72 or completely disengaged from the nut 72, so as to quickly complete the connection and disassembly between the connecting column 5 and the fixing column 4. By adjusting the connection or disassembly between the connecting column 5 and the fixing column 4, the first roller brush body 21 and the second roller brush body 31 can be used simultaneously or separately, thereby meeting different usage requirements, thereby improving the flexibility and convenience of use of the double roller paint brush.
[0036] Furthermore, the ends of the fixing column 4 and the connecting column 5 that are close to each other are respectively fixed with a first bevel tooth 41 and a second bevel tooth 51, and the first bevel tooth 41 is meshed with the second bevel tooth 51; when the connecting column 5 and the fixing column 4 are locked by using the locking assembly 7, the first bevel tooth 41 and the second bevel tooth 51 are aligned and meshed accurately, and the meshing of the first bevel tooth 41 and the second bevel tooth 51 can further ensure the stability of the position locking between the connecting column 5 and the fixing column 4.
[0037] Furthermore, a non-slip handle 11 is fixedly installed at one end of the handheld frame 1 away from the fixed column 4; when the double-roller paint brush needs to be used, the user only needs to hold the position of the non-slip handle 11, and by operating the non-slip handle 11, the moving direction and speed of the double-roller paint brush can be controlled, thereby ensuring a uniform brushing effect.
[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
