Description

Technical Field

[0001] This utility model relates to the field of concrete surface roughening technology, and in particular to a long-handled concrete surface roughening roller. Background Technology

[0002] In the process of concrete construction, roughening the concrete surface is an important step. Because the surface of freshly poured concrete is smooth, in order to avoid delamination or peeling due to the smooth surface, roughening can create texture on the surface and significantly improve the bonding strength by increasing the contact area. Therefore, a long-handled concrete surface roughening roller is used for roughening.

[0003] A long-handled concrete surface textured roller is a handheld tool used to texture the surface of concrete. Specifically, the operator holds the long handle of the device, aligns the roller with a specific texture with the concrete surface that has not fully hardened, and rolls the roller on the concrete surface by pushing or pulling the long handle. However, when the roller wears out or when it is necessary to replace the textured parts of different specifications, the existing technology requires using tools to loosen the fixing screws and then disassembling the entire textured roller device for replacement, which results in the problem of inconvenient device disassembly. Utility Model Content

Fixing bracket 1 4 and fixing bracket 2 5 are mainly used to fix folding rod 3 3 and quick-release assembly. Quick-release assembly is mainly used to facilitate the replacement of the roughened gear cylinder 9. The quick-release assembly has a fixing handle 11 that is internally connected to the fixing post 6, which is mainly used to fix the roughened gear cylinder 9. A spring 10 is set on the outside of the fixing post 6, which is mainly used to prevent the roughened gear cylinder 9 from tilting. At the same time, in order to facilitate the removal and replacement of the roughened gear cylinder 9, one end of the fixing post 6 is provided with a threaded part 7, which is used with a fixing nut 8, mainly used to fix one end of the quick-release assembly.

[0019] Reference Figures 2-3The quick-release assembly includes a fixed handle 11, which is rotatably connected to the outside of one end of a fixed post 6. A pad 12 is slidably connected to the upper outside of the fixed post 6, and the pad 12 is located at the bottom of the fixed handle 11. A hinge 13 is fixedly connected to the inside of the folding rod 1, and a connecting post 14 is fixedly connected to the lower surface of the hinge 13. A connecting post 2 15 is rotatably connected to the inside of the connecting post 14, and a hinge 2 16 is fixedly connected to the upper surface of the connecting post 2 15. Specifically, the fixing post 6 is mainly used to fix the gasket 12. The recess of the gasket 12 interacts with the outer edge of the fixing handle 11 to fix the other end of the quick-release assembly. The hinge 13 and hinge 2 16 are mainly used to connect the folding rod 1, folding rod 2, and folding rod 3. The connecting post 14 is used to connect the connecting post 2 15 to achieve the reverse rotation of the hinge, thereby achieving the folding effect.

[0020] Reference Figures 3-4 The upper interior of hinge 16 has a spring post 17, and the bottom end of the spring post 17 is fixedly connected to a buckle 18, which is slidably connected to the upper interior of hinge 16.

[0021] Working principle: When it is necessary to replace the brushed gear cylinder 9, turn the fixing handle 11 above the fixing post 6 in the opposite direction on one side, and rotate the fixing nut 8 below the fixing post 6 on the other side. When you feel no clamping force, you can easily pull out the fixing post 6, which can achieve the effect of quickly disassembling the brushed gear cylinder 9. When it is necessary to fix the brushed gear cylinder 9, first pass the brushed gear cylinder 9 through the fixing post 6, and then pass the fixing post 6 through the fixing hole of the fixing bracket 2 5. Adjust the fixing nut 8 on the threaded part 7 to the appropriate tightness. Then turn the fixing handle 11 to rotate in a circle. When the brushed gear cylinder 9 is in the right position, adjust the fixing nut 8 to fit tightly against the fixing bracket 2 5. On the other side, rotate the fixing handle 11 so that the lower edge of the fixing handle 11 fits tightly against the recess of the gasket 12. After fitting, press the fixing handle 11 to be parallel to the fixing post 6 to complete the effect of fixing the roller. When a folding mechanism is needed, the two hinges are connected by the connecting post 14 of hinge 13 and the connecting post 15 of hinge 26, allowing them to rotate in opposite directions around the same axis until the included angle is 180°, thus achieving the folding effect. At the same time, the quick-release and folding mechanisms enable the rapid replacement and folding of the roughened gear cylinder 9, facilitating storage.
