DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] In order to clearly and completely describe the objectives, technical solutions of the present utility model and make the advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only a part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] Please refer to Figures 1-4, the present utility model provides a technical solution: a roller brush convenient for painting, comprising: a storage cylinder 1 and a brush sleeve 12. One end of the storage cylinder 1 is rotatably connected to a rotating rod 3 through a rotating sleeve 2. The rotating sleeve 2 is a bearing, and one end outer wall of the rotating sleeve 2 is fixedly welded to the outer wall of the storage cylinder 1. One end of the rotating rod 3 is inserted into the inner side of the rotating sleeve 2 and welded to its inner wall. The storage cylinder 1 can rotate at one end of the rotating rod 3. Two groups of leakage holes are symmetrically arranged on the outer wall of the storage cylinder 1. One end of the storage cylinder 1 is fixedly provided with an injection pipe 4. The inner end of the injection pipe 4 is communicated with the inside of the storage cylinder 1. The outer end of the injection pipe 4 is provided with an external thread and is threadedly connected to a sealing cover 5 through the external thread. The painting material can be injected into the storage cylinder 1 through the injection pipe 4.
[0022] A pressure ring 7 is installed at the end of the storage cylinder 1 where the rotating sleeve 2 is installed. A number of first threaded holes 6 are evenly arranged on the outer side of one end of the storage cylinder 1. The first threaded holes 6 are located outside the rotating sleeve 2. A number of bolt holes are evenly arranged on the side wall of the pressure ring 7. A fixing bolt 8 is inserted into the bolt holes. One end of the fixing bolt 8 passes through the bolt holes and is threadedly connected to the inner wall of the first threaded holes 6 to fix the pressure ring 7, playing a role in facilitating the disassembly and assembly of the pressure ring 7. The rotating sleeve 2 and the injection pipe 4 are located inside the pressure ring 7, without affecting the injection of paint and the rotation of the storage cylinder 1.
[0023] A pressing plate 10 is installed at the other end of the storage cylinder 1. A second threaded hole 9 is opened at the center of the other end of the storage cylinder 1. A bolt hole is opened at the center of the side wall of the pressing plate 10. A fixing bolt 11 is inserted into the bolt hole. One end of the fixing bolt 11 passes through the bolt hole and is threadedly connected to the inner wall of the second threaded hole 9 to fix the pressing plate 10, playing a role in facilitating the disassembly and assembly of the pressing plate 10. The diameters of the pressing plate 10 and the pressure ring 7 are the same as the diameter of the storage cylinder 1, facilitating the fixing of the brush sleeve 12 and not affecting the use of the brush sleeve 12 at the same time.
[0024] Connection cloths 13 are fixedly installed at both the front and rear ends of the brush sleeve 12. The brush sleeve 12 is sleeved on the outer wall of the storage cylinder 1, and the connection cloth 13 is fixedly connected to both ends of the storage cylinder 1 through the pressure ring 7 or the pressing plate 10, fixing the brush sleeve 12 at the outer end of the storage cylinder 1, playing a role in facilitating the disassembly and assembly of the brush sleeve 12. The paint in the storage cylinder 1 wets the brush sleeve 12 through the leakage holes, and can continuously provide paint for the brush sleeve 12, increasing the painting time of the brush sleeve 12. There is no need to repeatedly immerse the roller brush in the paint bucket, improving work efficiency.
[0025] In actual use, the pressing plate 10 and the pressing ring 7 are unscrewed from the storage cylinder 1, and then the brush sleeve 12 is sleeved on the outer wall of the storage cylinder 1. The connecting cloths 13 at both ends of the brush sleeve 12 are respectively located at both ends of the storage cylinder 1. Then, the pressing plate 10 and the pressing ring 7 are fixed on the storage cylinder 1 to press the connecting cloth 13, thereby fixing the brush sleeve 12. Then, the coating material is injected into the storage cylinder 1 through the injection pipe 4. The coating material leaks onto the brush sleeve 12 through the leakage holes to wet the brush sleeve 12, which can continuously provide the coating material for the brush sleeve 12, increase the brushing time of the brush sleeve 12, and eliminate the need to repeatedly dip the roller brush into the coating material bucket, thus improving the work efficiency.
