[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The utility model provides a technical solution, such as Figure 1-Figure 5 As shown; a paint roller brush for preventing material from falling off, comprising a smear rod 1, an internally threaded sleeve 11 being installed at the lower end thereof, an adjusting stud 111 being installed at the internal thread of the internally threaded sleeve 11, an adjusting handle 112 being installed at the lower end of the adjusting stud 111, the adjusting handle 112 being located at the lower end of the smear rod 1, an adjusting rod 113 being installed at the upper end of the adjusting stud 111, the upper end of the adjusting rod 113 extending above the smear rod 1, and a fixing magnet 114 being installed.

[0029] In the embodiment of the present utility model, the internal threaded sleeve 11 cooperates with the thread of the adjusting stud 111, so that the adjusting rod 113 can drive the fixed magnet 114 to rise and fall, and then the fixed magnet 114 can rise and contact the fan-shaped collecting barrel 124, so that the fixed magnet 114 can use magnetic force to adsorb and fix the fan-shaped collecting barrel 124, so that when the roller brush 134 sticks to the material, the fan-shaped collecting barrel 124 can pour the collected paint back into the paint barrel.

[0030] The drip-proof frame 12 is installed at the upper end of the coating rod 1. Its shape is U-shaped. Arc-shaped seats 121 are installed at both ends. A positioning tube 122 is installed inside the arc-shaped seat 121. A rotating sleeve 123 is movably sleeved on the positioning tube 122. A fan-shaped collecting cylinder 124 is arranged inside it. Both ends of the fan-shaped collecting cylinder 124 are connected to the rotating sleeve 123. Short-axis sliding outlets 125 are provided on the arc-shaped seat 121, the positioning tube 122, and the rotating sleeve 123. The central angles of the arc-shaped seat 121, the positioning tube 122, and the rotating sleeve 123 are 240°.

[0031] In the embodiment of the present utility model, the fan-shaped collecting cylinder 124 can be automatically adjusted by gravity by means of the sliding connection between the rotating sleeve 123 and the positioning tube 122, so that it is always located below the roller brush 134 to collect the dripping paint.

[0032] In the embodiment of the present utility model, the short-axis sliding outlets 125 provided on the arc-shaped seat 121, the positioning tube 122, and the rotating sleeve 123 enable the fixed short axis 133 to move out of the positioning tube 122, so that the coating frame 13 can move the roller brush 134 away from the fan-shaped collecting cylinder 124 to facilitate the sticking of the roller brush 134 with the material.

[0033] In the embodiment of the present utility model, the central angles of the arc-shaped seat 121, the positioning tube 122, and the rotating sleeve 123 are 240°, which can prevent the fan-shaped collecting cylinder 124 from falling off during rotation and ensure the normal use of the device.

[0034] The coating frame 13 is arranged outside the drip-proof frame 12. A sliding sleeve 131 is installed at its center. The sliding sleeve 131 is slidably sleeved on the coating rod 1. Fixed seats 132 are installed at both ends. Fixed short axes 133 are installed on the fixed seats 132. A roller brush 134 is installed between the two fixed short axes 133. The adjusting pull rod 14 is arranged on the outer surface of the coating rod 1 and is movably connected to the sliding sleeve 131 at one end. A fixing ring 141 is sleeved on it. The fixing ring 141 is fixedly connected to the coating rod 1. A clamping handle 142 is arranged on one side of the other end. The positioning clamping column 15 is arranged on the outer surface of the coating rod 1 and is located at the upper and lower ends of the moving track of the clamping handle 142 and on both sides of the clamping handle 142.

[0035] In the embodiment of the present utility model, the coating frame 13 can be adjusted by driving the adjusting pull rod 14 through the clamping handle 142 and positioned by the positioning clamping column 15, so that the coating frame 13 can move the roller brush 134 for position adjustment, thereby preventing the fan-shaped collecting cylinder 124 from contacting the paint when the roller brush 134 picks up the paint, avoiding the paint from falling to the ground and reducing waste. Preferably, the fixed short axis 133 moves into the positioning tube 122 through the short-axis sliding outlet, and the lower end of the roller brush 134 moves into the fan-shaped collecting cylinder 124.

[0036] Preferably, when the smear frame 13 moves upward with the adjustment rod 14, as the smear frame 13 gradually approaches the anti-drip frame 12, the roller brush 134 moves out of the fan-shaped collecting cylinder 124 and gradually moves out of the anti-drip frame 12; so that the roller brush 134 can be away from the fan-shaped collecting cylinder 124, thereby facilitating the roller brush 134 to pick up paint.

[0037] Preferably, after the fixed magnet 114 extends with the adjusting rod 113, it contacts the lower end of the fan-shaped collecting cylinder 124 and fixes the fan-shaped collecting cylinder 124 by magnetic force; to prevent the fan-shaped collecting cylinder 124 from rotating to above the roller brush 134 during the paint sticking process, thereby avoiding contact with the paint, and at the same time making it convenient to pour the paint collected inside the fan-shaped collecting cylinder 124 back into the paint cylinder.

[0038] Preferably, the fan-shaped collecting barrel 124 is always located at the lower end of the roller brush 134 by its own gravity, so that it can always collect the dripping paint to prevent the paint from falling on the ground and the staff.

[0039] Specifically, when the present invention is used and the paint needs to be picked up, first, the applicator rod 1 is placed vertically, and then the staff manually rotates the adjustment handle 112 to rotate the adjustment stud 111, and through the threaded connection with the internal threaded sleeve 11, the adjustment rod 113 is driven to rise, so that the adjustment rod 113 pushes the fixed magnet 114 to rise, so that the fixed magnet 114 contacts the lower end of the fan-shaped collecting tube 124, and the fan-shaped collecting tube 124 is fixed by magnetic force;

[0040] Subsequently, the staff pushes the clamping handle 142 to rotate the adjusting rod 14 and move the clamping handle 142 out from between the two positioning posts 15. The staff then pushes the clamping handle 142 upward to cause the adjusting rod 14 to drive the sliding sleeve 131 to rise, thereby causing the smear frame 13 to drive the roller brush 134 to rise and separate the roller brush 134 from the fan-shaped collecting cylinder 124.

[0041] When the smear frame 13 rises to the highest height, the clamping handle 142 is moved again to be clamped between the two positioning clamping columns 15 above. At this time, the roller brush 134 can be inserted into the paint barrel to contact the paint and stick the paint. At the same time, the fan-shaped collecting barrel 124 is in an inverted state during the sticking process, and the dripping paint collected inside is poured back into the paint barrel by tilting the fan-shaped collecting barrel 124.

[0042] When the gluing is completed, the staff will take out the roller brush 134 from the paint and wait for a certain time in the air to allow the paint to drip back into the paint barrel by gravity as much as possible. At the same time, the staff will remove the clamping handle 142 from the positioning clamping column 15, and then pull the clamping handle 142 to make the coating frame 13 drive the roller brush 134 close to the anti-drip frame 12, and move the fixed short shaft 133 back into the positioning tube 122. At the same time, the fan-shaped collecting cylinder 124 is put on the roller brush 134 again.

[0043] Then, the adjustment handle 112 is rotated in the opposite direction, so that the adjustment rod 113 drives the fixed magnet 114 to separate from the fan-shaped collecting cylinder 124. Then, the fan-shaped collecting cylinder 124 moves to the bottom of the roller brush 134 by its own gravity, so that the paint dripping from the roller brush 134 is collected in the fan-shaped collecting cylinder 124.

[0044] Then the staff can lift the painting rod 1, make the roller brush 134 contact the wall, and paint the wall. When the painting rod 1 is moved, as the painting rod 1 moves and the angle changes, the fan-shaped collecting cylinder 124 uses its own gravity to always rotate to the bottom of the roller brush 134, so as to collect the paint dripping from the roller brush 134.
