Description

Technical Field

[0001] The utility model relates to the technical field of laser printers, in particular to a magnetic core structure of a laser printer. Background Art

[0002] The toner cartridges in laser printers, laser copiers and laser all-in-ones are the main components in graphic output. The toner cartridges provide toner for imaging on paper. In some models of printers, the toner in the toner cartridges contains ferrite, which allows the toner to be absorbed by the magnetic force of the magnetic core and then transferred to the paper for development. Different printers require different magnetic cores, and they are rarely interchangeable.

[0003] After searching, the existing patent publication number is CN211123627U, which is a new type of laser printer core. By setting rotatable connecting screws and connecting screw holes on the magnetic core, the clamp and the connector, the overall connection and installation of the magnetic core is more convenient and quick. By setting the magnetic core to a multi-section connection, the length of the magnetic core can be easily changed, and the scope of use is wider. It can be adapted to laser printers of various models and brands, reducing the mold development cost and facilitating the mass production of the magnetic core. By setting multiple protrusions on the magnetic core, the magnetic force of the magnetic core is more concentrated, reducing the use of raw materials.

[0004] However, the above patent has certain defects. The outer wall of the magnetic core body is provided with a protrusion, and it is not a complete cylinder. At this time, the initial angle before twisting the connection cannot be determined. It is difficult to ensure the alignment of the protrusions when the magnetic core body is connected by connecting screws and connecting screw holes. As a result, the multi-segment magnetic core body is uneven after connection and installation and is difficult to put into use, which reduces the use efficiency of the laser printer. Utility Model Content

[0005] In order to solve the above technical problems, the utility model proposes a laser printer core structure, which ensures that the angles of the two are consistent, and can be rotated for connection after being pushed and no longer limited. After the threaded tube and the threaded groove are fully connected, the two core bodies are also connected to them, avoiding the phenomenon that the multi-segment core body is uneven and difficult to put into use after connection and installation.

[0006] The technical solution to achieve the purpose of the utility model is: a laser printer core structure, including a core body, a threaded groove is provided on one side outer wall of the core body, a circular groove one is provided on one side outer wall of the core body, and limiting blocks are provided at the four corners of the inner wall of the circular groove one, a threaded tube is fixedly connected to the other side outer wall of the core body, a supporting block is provided on the other side outer wall of the core body, a mounting groove is provided on the other side outer wall of the supporting block, a spring is fixedly connected to the one side inner wall of the mounting groove, a supporting plate is fixedly connected to the other side outer wall of the spring, a fixing block is slidably connected to the inner wall of the mounting groove, an inner plate is fixedly connected to the one side outer wall of the fixing block, a connector is fixedly connected to the other side outer wall of the fixing block, limiting holes are provided at the four corners of the outer wall of one side of the inner plate, limiting rods are fixedly connected at the four corners of the inner wall of the other side of the mounting groove, and limiting grooves are provided at the four corners of the outer wall of the other side of the connector.

[0007] In some embodiments, the limiting blocks are all matched with the size of the limiting grooves, and the limiting holes are all matched with the size of the limiting rods.

[0008] In some embodiments, the inner plate is slidably connected to the inner wall of the installation groove, a circular groove 2 is formed on an outer wall of one side of the inner plate, and the support plate is slidably connected to the inner wall of the circular groove 2.

[0009] In some embodiments, the support plate, the inner plate and the fixing block are all cylindrically shaped, and the threaded tube is adapted to the size of the threaded groove.

[0010] In some embodiments, the diameter of the circular groove 1 is smaller than the diameter of the thread groove, and the diameter of the support block is smaller than the diameter of the threaded tube.

[0011] In some embodiments, protrusions are arranged at four corners of the outer wall of the magnetic core body, and the outer wall of the protrusions is provided with an adsorption surface layer, a conductive surface layer and a static electricity generating layer in sequence.

[0012] Compared with the prior art, the present invention has the following significant advantages:

[0013] The utility model is provided with a magnetic core body, a connecting head, an inner plate, a limiting rod, a threaded tube and a spring, and the two magnetic core bodies are pressed together after being pushed and clamped. At this time, the protrusions on the magnetic core bodies are kept at the same angle. When the magnetic core bodies are close together, the fixing block on the connecting head and the inner plate press the spring and the supporting plate, and the inner plate slides in the installation groove, the limiting rod is separated from the limiting hole on the inner plate, and the inner plate is no longer restricted. At this time, the threaded tube is just connected with the threaded groove, and the two magnetic core bodies are twisted until the threaded groove and the threaded tube are completely aligned. At this time, the angles of the two magnetic core bodies are consistent, and the angles are determined by the limited connecting head before the two magnetic core bodies are connected to ensure that the angles of the two are consistent. After being pushed and no longer limited, they can be rotated for connection. After the threaded tube is completely connected to the threaded groove, the two magnetic core bodies are also just connected to it, so as to avoid the phenomenon that the multi-segment magnetic core body is uneven and difficult to be put into use after being connected and installed, thereby improving the use efficiency of the laser printer.

[0014] The problem that the outer wall of the magnetic core body is provided with a protrusion and is not a complete cylinder, and the initial angle before twisting and connecting cannot be determined, and it is difficult to ensure the protrusions are aligned when the magnetic core body is connected by connecting screws and connecting screw holes, resulting in the problem that the multi-segment magnetic core body is uneven after connection and installation and is difficult to put into use.
