Description

Technical Field

[0001] The utility model belongs to the technical field of furniture, and in particular relates to a toner cartridge end cover structure capable of post-installing a chip. Background Art

[0002] Laser printers, developed from laser typesetting technology in the late 1980s, became popular in the mid-1990s. They are a printing output device that combines laser scanning and electrophotography technologies. Their basic operating principle is that binary data transmitted from a computer is converted into a video signal by a video controller. The video signal is then converted into a laser drive signal by a video interface / control system. A laser scanning system then generates a laser beam carrying the character information. Finally, an electrophotographic system creates an image from the laser beam and transfers it to paper. Compared to other printing devices, laser printers offer advantages such as faster printing speeds and higher image quality, but they are relatively expensive to use.

[0003] Among them, the toner cartridge is a very important component in the laser printer. The quality of the toner cartridge will directly affect the printing quality, and the life of the toner cartridge will affect the printing cost.

[0004] Existing toner cartridges have complex end cap structures, making them difficult to install, including the chip. This results in low production efficiency, inconvenient maintenance, and a short lifespan, leading to increased costs. Furthermore, users must remove the end cap to refill toner during use. Furthermore, most end caps are not securely attached to the chip, making them prone to falling out or shifting, impacting printing. Utility Model Content

[0005] The utility model provides a toner cartridge end cover structure capable of post-installing a chip, so as to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A toner cartridge end cover structure for post-installed chips comprises an end cover, a chip holder and a swinging member, and is characterized in that the end cover is integrally formed with a powder adding hole, an auxiliary column, a limiting column, an auxiliary guide rail groove and a travel limiting plate; the swinging member is provided with a mounting hole, which is embedded in the inner side of the end cover through the cooperation between the mounting hole and the auxiliary column; the back of the chip holder is designed with a convex groove to cooperate with the auxiliary guide rail groove, so that the chip holder can be clamped in the upper slot hole of the swinging member after the chip holder is directional and inserted; the chip holder is designed with a clamping column to be movably assembled with the upper slot hole of the swinging member; the limiting column is formed on the movement path of the swinging member.

[0008] Preferably, the bottom edge, the side edge and the upper surface of the card column of the chip holder are all formed into an oblique slot surface with an inclined surface design.

[0009] Preferably, the edge of the upper slot of the swinging member is also an inclined slot surface designed in the form of an inclined surface.

[0010] Preferably, the angle of the oblique slot surface of the swinging member is opposite to the angle of the oblique slot surface of the clamping column.

[0011] Preferably, after the end cover with the swinging member is assembled on the toner cartridge, the chip holder is clamped into the upper slot of the swinging member by extrusion assembly.

[0012] Compared with the prior art, the advantages of the present invention are: the present invention allows the toner cartridge to be prepared as a semi-finished product through a reasonable structural design, which can then be added with carbon powder and installed with chips, thus solving the low efficiency problem of production only when there is demand in the past. Since the service life of the toner cartridge begins to be calculated after the chip is installed and the powder is filled, it will affect its use if stored for a long time. The present invention improves the end cover, chip holder and swing part, so that both the chip and carbon powder can be installed later. Specifically, it is based on the design of the powder adding hole and the extrusion assembly method of the chip holder and the swing part. Even if the chip holder is installed from the outside, it can still achieve the advantages of being installed in place and fitting firmly, and avoids the tediousness of removing the end cover and then installing it. In addition, the powder adding hole can also be used by users to add powder by themselves to extend the overall service life. The operation of installing the chip later in the present invention can also be realized by installing the corresponding chip according to the actual working equipment before use, thereby improving the practicality and flexibility of the present invention, thereby matching and applying to more different working machines.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 7 As shown, the present invention is a toner cartridge end cap structure capable of post-installing a chip. The present invention mainly comprises an end cap 1, a chip holder 2, and a swinging member 3. The end cap 1 is integrally formed with a powder feeding hole 10, an auxiliary loading column 11, a limiting column 12, an auxiliary loading guide groove 13, and a travel limiting plate 14. The powder feeding hole 10 is equipped with a hole plug to provide sealing protection during printing. The hole plug can be removed during toner addition to add toner into the cavity. After adding, the hole plug is re-inserted and sealed to ensure stable operation and prevent toner from spilling and affecting use. The auxiliary column 11 is for the swinging part 3 with the mounting hole 30 to be embedded and fixed. The end cover 1 with the swinging part 3 is first assembled on the toner cartridge. At this time, the toner cartridge can be used as a semi-finished product and then added with toner and the chip can be installed when it is shipped and used. This can greatly improve production efficiency, solve the problems of slow reproduction due to demand in the past, and avoid the problem of reduced service life due to long-term storage after production. At the same time, the end cover 1 is installed first, and it is ensured that the chip holder 2 can be clamped in the upper slot 31 of the swinging part 3 by extrusion assembly, and there will be no problem of the swinging part 3 falling off.

[0021] The limiting post 12 on the end cap 1 is also designed to work in conjunction with the swinging member 3. It is formed on the inner side of the end cap 1 on the movement path of the swinging member 3. After the swinging member 3 is assembled with the chip holder 2, it can swing within a range in conjunction with the tension spring, thereby driving the chip holder 2 to perform reciprocating working motion. The swinging range of the swinging member 3 is determined by the position of the limiting post 12 and the length of the upper slot 31, because the length of the upper slot 31 is the stroke length of the clamping post 21. Regarding the stroke, the end cap 1 is also designed with a stroke limiting plate 14 to further ensure the positioning of the utility model during assembly and the stability of the reciprocating movement during operation, avoiding overtravel during installation, improper installation, or overtravel and falling off during operation.

[0022] Regarding the chip holder 2, the back of the chip holder 2 is designed with a convex groove 20 to cooperate with the auxiliary guide groove 13. This design allows the chip holder 2 to be oriented and then clamped in the upper slot 31 of the swinging member 3, which plays a guiding role to ensure the previous direction and orientation of the chip holder 2 when it is installed. The same design also includes the bottom edge 22, side edge 23 and upper surface 24 of the card column 21 of the chip holder 2. The bottom edge 22, side edge 23 and upper surface 24 of the card column 21 are all formed into an oblique slot surface with an inclined design. The bottom edge 22 and side edge 23 can slide in more easily when the chip holder 2 is inserted into the end cover 1. Compared with the vertical cross-section, the oblique slot The surface allows the chip holder 2 to be inserted into the end cover 1 more smoothly, and the upper surface 24 of the card column 21 is designed to interact with the swing member 3. Specifically, the edge 32 of the upper slot 31 of the swing member 3 is also an oblique slot surface designed as an inclined surface, and it is worth noting that the angle of the oblique slot surface of the swing member 3 is opposite to the angle of the oblique slot surface of the card column 21. Therefore, when the chip holder 2 is squeezed downward to assemble, the oblique slot surface of the card column 21 can lift the swing member 3, thereby allowing the card column 21 to smoothly enter the upper slot 31. Thanks to the elastic deformation of the plastic part, the swing member 3 will reset in time to clamp the chip holder 2 in the upper slot 31 to achieve active assembly.

[0023] The utility model adopts a reasonable structural design to allow the toner cartridge to be prepared as a semi-finished product, and the toner and chip can be added later, thus solving the low efficiency problem of production only when there is demand in the past. Since the service life of the toner cartridge begins to be calculated after the chip is installed and the toner is filled, long-term storage will affect its use. At the same time, the tediousness of removing and reinstalling the end cover is avoided. In addition, the toner filling hole can also be used by the user to add toner by himself later to extend the overall service life.
