[0022] Reference Figure 1-5 The utility model provides an anti-splash paint roller brush, including a mounting frame 1, a handle 2 is fixedly connected to the bottom end of the mounting frame 1, a mounting groove 17 is opened on the right end surface of the mounting frame 1, and a plug plate 18 is slidably and detachably connected inside the mounting groove 17, and the plug plate 18 is fixedly connected to the mounting frame 1 through a bolt 11, and a connecting plate 5 is fixedly connected to the right end of the plug plate 18, and the connecting plate 5 and the plug plate 18 are an integrated structure, and the connecting plate 5 and the mounting frame 1 are fixedly connected to the inside of the connecting plate 5 and the mounting frame 1. A roller brush body 4 is installed between the connecting plate 5 and the mounting frame 1, and the roller brush Both left and right end surfaces of the main body 4 are provided with plug holes 13, and both plug rods 12 are connected to the roller brush main body 4 through the plug holes 13. A baffle 6 is installed inside the mounting frame 1, and the baffle 6 is located at the rear end of the roller brush main body 4. The baffle 6 can be used to block the paint splashed backward when the roller brush main body 4 is applying paint. The rear end of the baffle 6 is fixedly connected to two mounting blocks 7 that are symmetrically distributed on the left and right. The end surfaces of the two mounting blocks 7 that are close to each other are provided with slots 16. A locking mechanism is installed at the bottom end of the mounting frame 1, and the locking mechanism is connected to the mounting block 7 through the slot 16.

[0023] The locking mechanism includes a threaded barrel 14, a threaded rod 15, a movable seat 21, a connecting rod 10, an insert block 19 and a fixed shell 20. The bottom end of the mounting frame 1 is rotatably connected to the threaded barrel 14, the internal thread of the threaded barrel 14 is connected to the threaded rod 15, the circumferential surface of the threaded rod 15 is fixedly connected to the movable seat 21, the interior of the movable seat 21 is rotatably connected to the connecting rod 10, the bottom end of the mounting frame 1 is fixedly connected to the fixed shell 20, the interior of the fixed shell 20 is slidably connected to the insert block 19, the insert block 19 is slidably connected to the slot 16, and the connecting rod 10 is rotatably connected to the insert block 19. During operation, the baffle 6 can be quickly disassembled and installed under the action of the locking mechanism. By regularly disassembling the baffle 6, it is convenient to regularly clean and maintain the baffle 6, so that the baffle 6 always maintains a good anti-splash function. During specific operation, the threaded cylinder 14 is rotated to make the threaded rod 15 drive the movable seat 21 to move downward, which will drive the connecting rod 10 to rotate and move, and then drive the plug block 19 to gradually move away from the slot 16 until the plug block 19 is completely separated from the mounting block 7. Then the baffle 6 can be removed from the mounting frame 1 for replacement or cleaning.

[0024] Further, a flexible sleeve 3 is fixedly mounted on the circumferential surface of the handle 2. During work, the flexible sleeve 3 facilitates the staff to hold the handle 2 and use the roller brush body 4 to dip in paint and perform painting work.

[0025] Furthermore, the bottom end of the mounting frame 1 is fixedly connected to two telescopic rods that are symmetrically distributed on the left and right sides, and the output ends of the telescopic rods are fixedly connected to fixed blocks, and the fixed blocks are fixedly installed at the front end of the moving seat 21. During operation, under the action of the telescopic rods and the fixed blocks, the threaded barrel 14 rotates, so that the threaded rod 15 can drive the moving seat 21 to move more stably.

[0026] Furthermore, a positioning hole 9 is provided on the front face of the mounting frame 1, and a positioning block 8 is slidably connected inside the positioning hole 9. The positioning block 8 is fixedly installed in the mounting block 7 and is an integrated structure with the mounting block 7. During operation, the baffle 6 can be accurately installed in the mounting frame 1 under the cooperation of the positioning hole 9 and the positioning block 8.

[0027] Furthermore, a first mounting hole is formed on the upper end surface of the mounting frame 1, and a second mounting hole is formed on the upper end surface of the plug plate 18. The diameters of the first mounting hole and the second mounting hole are the same, and the bolt 11 passes through the first mounting hole and the second mounting hole, so that the plug plate 18 is fixedly connected to the mounting frame 1. During operation, when the roller brush body 4 needs to be disassembled, the bolt 11 is first disassembled, and then the connecting plate 5 and the plug plate 18 can be disassembled along the mounting groove 17, and then the roller brush body 4 can be disassembled and replaced.

[0028] Furthermore, the thread shape inside the threaded barrel 14 and the thread shape on the circumference of the threaded rod 15 are both triangular, and an irregular rotating block is fixedly connected to the circumference of the threaded barrel 14. During operation, the presence of the irregular rotating block facilitates the rotation of the threaded barrel 14, and because the triangular thread has a self-locking property, when the threaded barrel 14 stops rotating, the threaded rod 15 can be stably located in the threaded barrel 14.
