[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0026] Please see Figure 1-5 This utility model provides a technical solution:
[0027] A waterproof material roller brush includes a horizontal bar 1 and a brush cylinder 2 movably mounted on the horizontal bar 1. A connecting rod 3 is provided at one end of the horizontal bar 1, and a sleeve rod 4 is fixedly installed at the end of the connecting rod 3. A handle 5 is provided at the end of the sleeve rod 4. A limiting ring 6 is slidably mounted on the horizontal bar 1. Two sets of limiting rings 6 are provided. The brush cylinder 2 is positioned between the two sets of limiting rings 6. An installation port 7 is provided on the inner wall of the limiting ring 6. A spring 8 is provided in the installation port 7. A limiting block 9 is slidably mounted on the installation port 7. The two ends of the spring 8 are fixedly mounted to the limiting ring 6 and the limiting block 9, respectively, and the spring 8 is pressed between the limiting ring 6 and the limiting block 9. The edge of the limiting block 9 away from the spring 8 is set as an arc edge.
[0028] When installing the roller brush as a whole, the operator first inserts a limiting ring 6 into the crossbar 1, then inserts the brush cylinder 2 into the crossbar 1, and finally inserts another limiting ring 6 into the crossbar 1. After adjusting the positions of the three on the crossbar 1, the two sets of limiting rings 6 are close to but not in contact with the two ends of the brush cylinder 2, so as not to affect the rotation of the brush cylinder 2.
[0029] During the process of inserting the limiting ring 6 into the crossbar 1, the limiting block 9 is subjected to compressive force. The limiting block 9 is subjected to compressive force, which compresses the spring 8 and moves it into the mounting port 7. When the limiting ring 6 slides to the appropriate position, the spring 8 generates a reaction force, which makes the limiting block 9 stick tightly to the crossbar 1, thus limiting the limiting ring 6.
[0030] When applying waterproof material, the operator holds the handle 5 and uses the sleeve rod 4 and connecting rod 3 to pick up the brush tube 2 and dip it into the waterproof material before applying it.
[0031] This waterproof material roller can limit the two ends of the brush cylinder 2 of different lengths to prevent the brush cylinder 2 from rolling off course, thereby improving the stability of the waterproof material coating and making it highly practical.
[0032] The inner wall of the limiting ring 6 has an installation port 7, a spring 8, and a limiting block 9, which are provided with at least two sets of symmetrical components.
[0033] The mounting port 7, spring 8 and limiting block 9 on the inner wall of the limiting ring 6 are provided in at least two symmetrical sets, which can improve the stability of the limiting ring 6 on the crossbar 1, and thus improve the stability of limiting the brush cylinder 2.
[0034] A knob 10 is rotatably provided at the end of the sleeve rod 4, and a lead screw 11 is rotatably provided inside the sleeve rod 4. The rotating shaft end of the knob 10 is fixedly installed with the rotating shaft end of the lead screw 11. A movable rod 12 is slidably provided on the sleeve rod 4. The movable rod 12 is threadedly connected to the lead screw 11. The handle 5 is fixedly installed at the end of the movable rod 12.
[0035] When the operator needs to adjust the length of the roller brush, simply turn the knob 10. The knob 10 drives the lead screw 11 to rotate inside the sleeve 4. Since the movable rod 12 is threadedly connected to the lead screw 11 and slides on the sleeve 4, the rotation of the lead screw 11 will cause the movable rod 12 to slide along the sleeve 4, thereby changing the position of the movable rod 12 on the sleeve 4, and thus adjusting the length of the entire roller brush. This makes it easier for the operator to apply waterproof materials according to different construction scenarios and operating habits.
[0036] The dimensions of movable rod 12 are compatible with the inner diameter of sleeve rod 4;
[0037] The dimensions of the movable rod 12 are matched with the inner diameter of the sleeve rod 4, which ensures the stability of the brush length adjustment process.
[0038] A connecting frame 13 is fixedly installed at the end of the connecting rod 3, and a connecting block 14 is fixedly installed at the end of the crossbar 1. The size of the connecting block 14 is adapted to the size of the connecting frame 13, and the connecting block 14 and the connecting frame 13 are fixedly installed by screws 15.
[0039] When it is necessary to install the crossbar 1, the operator only needs to align the connecting block 14 at the end of the crossbar 1 with the connecting frame 13 at the end of the connecting rod 3, insert the connecting block 14 into the connecting frame 13, and then use screws 15 to fix the connecting block 14 to the connecting frame 13 to complete the installation of the crossbar 1. When it is necessary to disassemble the crossbar 1 for maintenance or replacement of parts, simply unscrew the screws 15 and remove the connecting block 14 from the connecting frame 13 to easily remove the crossbar 1 from the connecting rod 3. This facilitates easy disassembly and assembly of the crossbar 1 and makes it convenient for the assembly, maintenance and replacement of parts of the roller brush.
[0040] Working principle:
[0041] When installing the roller brush as a whole, the operator first inserts a limiting ring 6 into the crossbar 1, then inserts the brush cylinder 2 into the crossbar 1, and finally inserts another limiting ring 6 into the crossbar 1. After adjusting the positions of the three on the crossbar 1, the two sets of limiting rings 6 are close to but not in contact with the two ends of the brush cylinder 2, so as not to affect the rotation of the brush cylinder 2.
[0042] During the process of inserting the limiting ring 6 into the crossbar 1, the limiting block 9 is subjected to compressive force. The limiting block 9 is subjected to compressive force, which compresses the spring 8 and moves it into the mounting port 7. When the limiting ring 6 slides to the appropriate position, the spring 8 generates a reaction force, which makes the limiting block 9 stick tightly to the crossbar 1, thus limiting the limiting ring 6.
[0043] When applying waterproof material, the operator holds the handle 5 and uses the sleeve rod 4 and connecting rod 3 to pick up the brush tube 2 and dip it into the waterproof material before applying it.
[0044] This waterproof material roller brush can limit the two ends of the brush cylinder 2 of different lengths to prevent the brush cylinder 2 from rolling off course, thereby improving the stability of the waterproof material coating and making it highly practical.
[0045] in,
[0046] The mounting port 7, spring 8 and limiting block 9 on the inner wall of the limiting ring 6 are provided with at least two sets of symmetrical parts, which can improve the stability of the limiting ring 6 on the crossbar 1, and thus improve the stability of limiting the brush cylinder 2.
[0047] When the operator needs to adjust the length of the roller brush, simply turn the knob 10. The knob 10 drives the lead screw 11 to rotate inside the sleeve 4. Since the movable rod 12 is threadedly connected to the lead screw 11 and slides on the sleeve 4, the rotation of the lead screw 11 will cause the movable rod 12 to slide along the sleeve 4, thereby changing the position of the movable rod 12 on the sleeve 4, and thus adjusting the length of the entire roller brush. This makes it easier for the operator to apply waterproof materials according to different construction scenarios and operating habits.
[0048] The dimensions of the movable rod 12 are matched with the inner diameter of the sleeve rod 4, which ensures the stability of the roller brush length adjustment process;
[0049] When it is necessary to install the crossbar 1, the operator only needs to align the connecting block 14 at the end of the crossbar 1 with the connecting frame 13 at the end of the connecting rod 3, insert the connecting block 14 into the connecting frame 13, and then use screws 15 to fix the connecting block 14 to the connecting frame 13 to complete the installation of the crossbar 1. When it is necessary to disassemble the crossbar 1 for maintenance or replacement of parts, simply unscrew the screws 15 and remove the connecting block 14 from the connecting frame 13 to easily remove the crossbar 1 from the connecting rod 3. This facilitates easy disassembly and assembly of the crossbar 1 and makes it convenient for the assembly, maintenance and replacement of parts of the roller brush.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
