Description

Technical Field

[0001] The utility model relates to the technical field of toner cartridges, and more specifically, to a positioning structure for a toner cartridge. Background Art

[0002] A toner cartridge, also known as an ink powder box or a toner cartridge, is a copying consumable product provided for use in laser printers and multifunctional copiers. Toner is a solid powdery substance used to form text and images during the printing process. The toner cartridge contains toner inside, and this toner is transferred onto paper through a photosensitive drum (toner cartridge) in a laser printer to form the final printed content. The design and manufacturing quality of the toner cartridge directly affect the printing effect and printing cost. The main difference between a toner cartridge and an ink cartridge is that they are used for different types of printers respectively. Ink cartridges are mainly used for inkjet printers, while toner cartridges are used for laser printers and multifunctional copiers. In addition, the toner in the toner cartridge is solid, while the ink in the ink cartridge is liquid.

[0003] During the production process of the toner cartridge, assembly is required. The positioning structure can improve the assembly efficiency of the toner cartridge by people and provide convenience during the subsequent disassembly and assembly process by people. However, the existing positioning structure of the toner cartridge is relatively simple, and it is difficult to close the gaps on the toner cartridge after long-term use, resulting in looseness of the toner cartridge.

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a positioning structure for a toner cartridge, which has the advantage of more precise operation.

[0005] To achieve the above object, the utility model provides the following technical solution: A positioning structure for a toner cartridge, comprising: a bottom plate and an upper cover; a plurality of grooves are provided on one side of the bottom plate close to the upper cover, a plurality of first positioning blocks are fixed on one side of the upper cover close to the bottom plate, the first positioning blocks correspond to the grooves respectively, a plurality of flow guiding blocks and inserting plates are arranged on one side of the grooves, a plurality of through grooves are provided on the upper cover, the through grooves longitudinally penetrate the upper cover, and the inserting plates correspond to the through grooves respectively; first fixing blocks and second fixing blocks are arranged on both sides of the bottom plate, the second fixing blocks are arranged between the first fixing blocks, guide rods are connected between the first fixing blocks and the second fixing blocks, moving plates are slidably connected to the guide rods, connecting pieces are arranged on both sides of the upper cover, and inserting pins are rotatably connected to one ends of the moving plates away from the guide rods; a cross plate and a plurality of convex blocks are fixed on the bottom plate, a plurality of second positioning blocks are fixed on the upper cover, the second positioning blocks correspond to the cross plate respectively, and the cross plate is arranged between the convex blocks.

[0006] As a preferred technical solution of the present utility model, a plurality of gaskets are arranged on the bottom plate, and the gaskets are distributed in a rectangular array on the bottom plate; to buffer the pressure between the bottom plate and the upper cover.

[0007] As a preferred technical solution of the present utility model, the bolt is machined with threads, and threaded grooves are machined on both sides of the connecting piece, and the bolts correspond to the threaded grooves respectively; which facilitates people to strengthen the connection stability between the upper cover and the bottom plate.

[0008] As a preferred technical solution of the present utility model, elastic components are sleeved on the guide rods, and both ends of the elastic components are respectively connected to the second fixing block and the moving plate; which facilitates the automatic reset of the moving plate.

[0009] As a preferred technical solution of the present utility model, a plurality of grooves are machined on one side of the cross plate close to the upper cover, and the second positioning blocks correspond to the grooves respectively; which facilitates people to quickly position the upper cover and the bottom plate.

[0010] As a preferred technical solution of the present utility model, a limiting groove is opened on one side of the convex block, and a plurality of elastic pieces are fixed on one side of the upper cover, and limiting pieces are arranged on the elastic pieces; which facilitates the limiting of one side of the bottom plate and the upper cover.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: By arranging a plurality of block structures and notches on the upper cover and the bottom plate, the stability of the toner cartridge after assembly can be improved. Only simple positioning and clamping are required to quickly complete the assembly work, which ensures the work efficiency of people during assembly. Moreover, the structure is simple and the operation is convenient, enabling people to quickly get started. The locking structures arranged on both sides of the bottom plate can further strengthen the connection strength between the bottom plate and the upper cover. Even if the assembly gap of the toner cartridge is large after long-term use, the positioning effect of the bottom plate and the upper cover can still be achieved. Among them, the moving plate is fixed to the connecting block through bolts and automatically resets through elastic components, saving the physical strength consumed by people, extending the service life of the toner cartridge, and ensuring the use effect of the toner cartridge.

[0019] Wherein, a plurality of gaskets 4 are arranged on the bottom plate 1, and the gaskets 4 are distributed in a rectangular array on the bottom plate 1; buffering the pressure between the bottom plate 1 and the upper cover 2.

[0020] Wherein, the bolt 18 is processed with threads, and both sides of the connecting piece 10 are processed with thread grooves, and the bolt 18 corresponds to the thread grooves respectively; it is convenient for people to enhance the connection stability between the upper cover 2 and the bottom plate 1.

[0021] Among them, elastic components 17 are sleeved on the guiding rods 9, and two ends of the elastic components 17 are respectively connected to the second fixing blocks 16 and the moving plates 8; this facilitates the automatic reset of the moving plates 8.

[0022] Among them, a plurality of grooves are machined on one side of the cross plate 19 close to the upper cover 2, and the second positioning blocks 15 correspond to the grooves respectively; this facilitates people to quickly position the upper cover 2 and the bottom plate 1.
