DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0018] See also Figures 1 to 3 , which is the first embodiment of the utility model, and this embodiment provides a technical solution: a roller assembly that is easy to install, comprising two mounting frames 2 and a roller body 1 rotatably mounted between the two mounting frames 2, both ends of the roller body 1 are provided with a shaft 11, and the top surface of the mounting frame 2 is provided with a disassembly notch 21 corresponding to the shaft 11, and the shaft 11 is rotatably located at the inner bottom end of the disassembly notch 21;

[0019] The roller body 1 and the mounting frame 2 are also provided with a limiting rod 4. The two side surfaces of the mounting frame 2 are provided with rectangular sockets 22 which are connected with the disassembly notch 21. The limiting rod 4 is inserted into the two rectangular sockets 22. The limiting rod 4 is located above the shaft 11, which can effectively block the shaft 11, thereby realizing the rapid assembly between the roller body 1 and the mounting frame 2. In the subsequent operation, the roller body 1 and the mounting frame 2 can be quickly disassembled by simply pulling out the limiting rod 4.

[0020] The limiting mechanism 3 is also included. A rectangular notch 23 is penetrated through the bottom surface of the mounting frame 2. The limiting mechanism 3 includes a pull block 31, a movable rod 32 and a rod hole 33. The pull block 31 can be movably installed on the inner side of the rectangular notch 23. Two movable rods 32 are symmetrically welded and fixed on the top surface of the pull block 31. Plug holes 41 corresponding to the movable rods 32 are provided on the two end surfaces of the limiting through rod 4. The top end of the movable through rod 32 penetrates into the plug hole 41, which can stably limit the limiting through rod 4 and ensure the stability of the limiting through rod 4 itself. Subsequently, the pull block 31 only needs to be pulled down to release the limit of the limiting through rod 4 by the movable rod 32.

[0021] Among them, a rod hole 33 is opened through between the rectangular socket 22 and the rectangular notch 23, and the rod hole 33 corresponds to the movable insertion rod 32. A side groove 34 is opened on the inner wall of one side of the rod hole 33. A side slider 35 and a spring 36 are arranged in the side groove 34. One end of the side slider 35 is fixedly connected to the movable insertion rod 32. Under the pushing action of the spring 36, the side slider 35 is always against the top inner wall of the side groove 34 during daily use, and the top of the movable insertion rod 32 is always inserted in the insertion hole 41, maintaining the limiting stability of the limiting through rod 4, thereby ensuring the assembly stability between the mounting frame 2 and the roller body 1.

[0022] Among them, a cylindrical groove is opened on the inner wall of the bottom end of the side groove 34, and the bottom end of the spring 36 is inserted into the cylindrical groove, which can play an auxiliary limiting role for the spring 36 and prevent the spring 36 from deflecting.

[0023] The width of the disassembly notch 21 is matched with the outer diameter of the shaft rod 11 , so that the shaft rod 11 can be smoothly installed in the disassembly notch 21 .

[0024] In summary, when assembling the roller body 1 and the mounting frame 2 in the early stage, the shaft rods 11 at both ends of the roller body 1 are first placed into the disassembly and assembly notches 21 at the top of the mounting frame 2, and then the pull block 31 is pulled down to move the movable insertion rod 32 downward and make the side slider 35 compress the spring 36 until the top of the movable insertion rod 32 is completely pulled into the rod hole 33. At this time, the limiting penetration rod 4 can be inserted into the two rectangular sockets 22, and the limiting penetration rod 4 can pass through the disassembly and assembly notches 21 and be located above the shaft rod 11, thereby blocking and limiting the shaft rod 11. Then the pull block 31 is released, so that the spring 36 pushes the side slider 35 back to reset, so that the top of the movable insertion rod 32 can be By smoothly rebounding into the insertion hole 41, the limiting rod 4 can be stably limited, ensuring the limiting stability of the limiting rod 4 on the shaft rod 11, and ensuring the assembly stability of the roller body 1 and the mounting frame 2. If the roller body 1 and the mounting frame 2 need to be disassembled later, it is only necessary to pull the pull block 31 down again to move the top end of the movable insertion rod 32 out of the insertion hole 41, so as to release the limiting of the limiting rod 4 and pull the limiting rod 4 out of the rectangular socket 22. In the absence of the obstruction of the limiting rod 4, the shaft rod 11 can be directly taken out from the upper end opening of the disassembly notch 21, so as to realize the rapid disassembly of the roller body 1 and the mounting frame 2, and facilitate the subsequent disassembly and maintenance of the roller assembly. Example

[0025] See also Figures 1 to 3 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that the auxiliary positioning structure can be set during the assembly process of the roller body 1 and the mounting frame 2 to play an auxiliary positioning role for the roller body 1 and the shaft 11, so as to keep the roller body 1 in a suitable installation position.

[0026] Specifically, it also includes an auxiliary positioning structure, which is arranged between the disassembly notch 21 and the shaft rod 11. The auxiliary positioning structure includes a rectangular insert 24, a positioning protrusion 25 and an annular positioning groove 12. The rectangular insert 24 is embedded in the bottom inner wall of the disassembly notch 21, and the top surface of the rectangular insert 24 is welded and fixed with a positioning protrusion 25. The surface of the shaft rod 11 is provided with an annular positioning groove 12 corresponding to the positioning protrusion 25. The positioning protrusion 25 is inserted into the annular positioning groove 12. When the roller body 1 is assembled with the mounting frame 2 in the early stage, the shaft rod 11 can be auxiliary positioned, so that after the shaft rod 11 is pushed into the inner side of the disassembly notch 21, the positioning protrusion 25 will also enter the annular positioning groove 12, which plays a role in axial positioning of the shaft rod 11, prevents the shaft rod 11 and the roller body 1 from lateral displacement, and keeps the roller body 1 in a suitable installation position. At the same time, the annular structure design of the annular positioning groove 12 does not affect the subsequent normal rotation of the shaft rod 11.

[0027] A rectangular embedding groove corresponding to the rectangular embedding block 24 is provided on the inner wall of the bottom end of the disassembly and assembly notch 21 for embedded installation of the rectangular embedding block 24 .

[0028] Although the embodiments of the present invention have been shown and described (see the detailed description above for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
