[0022] See also Figure 1-4 The utility model provides a technical solution: a toner cartridge magnetic roller that is easy to assemble, comprising an aluminum tube 1 and a transmission bracket 2, the transmission bracket 2 comprising a connecting rod 21, a bracket rod 23 being fixedly mounted at one end of the connecting rod 21; a positioning plate 24 being fixedly mounted at the other end of the connecting rod 21, an external thread groove 25 being provided on the outside of one end of the connecting rod 21 close to the positioning plate 24, an exhaust hole 3 being symmetrically provided at one end of the aluminum tube 1, an internal thread groove 12 being provided at one end of the aluminum tube 1 close to the transmission bracket 2, and the transmission bracket 2 being detachably mounted in the inner wall of one end of the aluminum tube 1; the transmission bracket 2 is formed into a toner cartridge magnetic roller by connecting with the aluminum tube 1, and then the exhaust hole 3 at one end of the aluminum tube 1 can be filled with water to achieve the purpose of cleaning, and the toner cartridge magnetic roller is cleaned internally through the exhaust hole 3, which is a prior art solution and will not be elaborated herein.

[0023] When assembling the transmission bracket 2 and the aluminum tube 1 in the toner drum magnetic roller, first insert the bracket rod 23 in the transmission bracket 2 from the end of the aluminum tube 1 away from the exhaust hole 3, so that the bracket rod 23 at one end of the transmission bracket 2 can extend from the connecting groove 11.

[0024] One end of the connecting rod 21 in the transmission bracket 2 is connected to one end of the aluminum tube 1 through the connecting groove 11, and is threadedly connected to the internal thread groove 12 through the external thread groove 25, so that the aluminum tube 1 and the transmission bracket 2 in the toner drum magnetic roller can be assembled by threaded connection, which avoids stamping by external stamping equipment, causing the end of the aluminum tube 1 to be deformed by a large force, stretched and damaged. At the same time, the positioning plate 24 at one end of the connecting rod 21 is located in the inner cavity of the aluminum tube 1, so that the connection between the transmission bracket 2 and the aluminum tube 1 can be limited, making the connection point more stable, ensuring the assembly integrity of the toner drum magnetic roller, and facilitating subsequent disassembly and replacement.

[0025] In some embodiments, Figure 3-4 As shown, a connecting groove 11 is provided through the middle of one end of the aluminum tube 1 near the transmission bracket 2, and an internal thread groove 12 is provided in the inner wall of the connecting groove 11. Transmission planes 22 are provided on both sides of the annular surface of one end of the connecting rod 21 near the bracket rod 23. The diameter of the connecting rod 21 matches the inner diameter of the connecting groove 11. The transmission bracket 2 is connected with the internal thread groove 12 at one end of the aluminum tube 1 through the external thread groove 25. One end of the connecting rod 21 in the transmission bracket 2 is connected with one end of the aluminum tube 1 through the connecting groove 11, and is threadedly connected with the internal thread groove 12 through the external thread groove 25, so that the aluminum tube 1 and the transmission bracket 2 in the toner drum magnetic roller can be assembled by threaded connection, thereby avoiding stamping and forming by external stamping equipment, which causes the end of the aluminum tube 1 to be subjected to a large force and deformed, and stretched and damaged.

[0026] In some embodiments, Figure 3 As shown, the side section of the aluminum tube 1 is a T-shaped structure, and the exhaust holes 3 are symmetrically arranged on both sides of the outside of the transmission bracket 2. The transmission bracket 2 is connected with the aluminum tube 1 to form a toner drum magnetic roller, and then the exhaust holes 3 at one end of the aluminum tube 1 can be filled with water to achieve the purpose of cleaning.

[0027] In some embodiments, Figure 3 As shown, the positioning plate 24 is located in the inner cavity of the aluminum tube 1, the diameter of the positioning plate 24 is smaller than the inner diameter of the aluminum tube 1, and the diameter of the positioning plate 24 is larger than the inner diameter of the connecting groove 11, and the positioning plate 24 at one end of the connecting rod 21 is located in the inner cavity of the aluminum tube 1, so that the connection between the transmission bracket 2 and the aluminum tube 1 can be limited, so that the connection between the transmission bracket 2 and the aluminum tube 1 is tightly connected, making the connection more stable.

[0028] By rotating the bracket rod 23, the external thread groove 25 at one end of the connecting rod 21 is threadedly connected with the internal thread groove 12 in the connecting groove 11 at one end of the aluminum tube 1, until the positioning plate 24 at one end of the connecting rod 21 is connected and blocked from the connecting groove 11 in the inner wall of the aluminum tube 1, so that the aluminum tube 1 and the transmission bracket 2 in the toner drum magnetic roller can be assembled by threaded connection, thereby avoiding the stamping and forming by external stamping equipment, which causes the end of the aluminum tube 1 to be subjected to large force and deformation, and is stretched and damaged. At the same time, the positioning plate 24 at one end of the connecting rod 21 is located in the inner cavity of the aluminum tube 1, so that the connection between the transmission bracket 2 and the aluminum tube 1 can be limited, making the connection point more stable, ensuring the assembly integrity of the toner drum magnetic roller, and facilitating subsequent disassembly and replacement.
