Description

Technical Field

[0001] This utility model belongs to the field of printing consumables technology, and specifically relates to a processing box with a novel side cover. Background Technology

[0002] In the field of printing consumables, the processing cartridge (such as the photosensitive drum, developer cartridge, and ink cartridge) is one of the core components of a printer, and its structural design directly affects the performance, assembly efficiency, and ease of maintenance. With the continuous upgrading of printing equipment and the increasing demands of users for print quality, the structural optimization of the internal components of the processing cartridge has become a key area of ​​continuous improvement for those skilled in the art. In existing technologies, the processing cartridge typically includes multiple functional components such as gear assemblies, chip holders, and side covers. The gear assembly is used to transmit power between moving parts during printing; while the chip holder houses the identification chip, which typically stores data such as the processing cartridge's model information, usage status, and remaining lifespan, allowing the printer to read and identify the processing cartridge. To simplify the mold structure and overall assembly process, some existing technologies integrate the gear end cover and chip holder into a single structure using injection molding or other methods.

[0003] However, while this integrated design reduces the number of parts to some extent, it has revealed several problems in practical applications. First, since the gear end cap and the chip holder are the same injection-molded part, the material selection must take into account the functional requirements of both. For example, the gear end cap needs to have a certain strength and wear resistance, while the chip holder may place more emphasis on conductivity or insulation. This compromise in material selection may lead to a decrease in performance in one aspect, thereby affecting the overall reliability of the product.

[0004] Secondly, the integrated structure presents significant limitations during assembly. Because the chip holder's position is constrained by the overall layout of the gear end cover, its installation angle and positional accuracy are difficult to adjust flexibly, thus affecting the signal connection stability between the chip and the printer's main control circuit. Furthermore, during production assembly, if a component malfunctions, the entire assembly must be replaced, resulting in unnecessary material waste and increased costs. Moreover, the inseparability of the chip holder from the gear end cover complicates subsequent maintenance and replacement. For example, in cases of chip damage or aging, traditional structures often require complete disassembly of the gear assembly to replace the chip holder, increasing maintenance difficulty and reducing the user experience. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a processing box with a novel side cover. By providing a brand-new chip holder structure and separating the chip holder from the gear end cover, a higher degree of assembly freedom and stronger adaptability can be achieved.

[0006] To solve the above problems, the technical solution adopted by the present utility model is as follows: A processing cartridge with a novel side cover, comprising: a gear end cover and a chip holder, the gear end cover is integrally formed with the processing cartridge body, the chip holder is fixed to the gear end cover by fasteners, the chip holder is provided with a fixing part and a connecting part, the connecting part includes a first connecting part and a second connecting part, a horizontally placed first hook is provided at the center of the first connecting part, the first connecting part is symmetrically arranged with the first hook as the center, the second connecting part is located on the right side of the first connecting part, a vertically placed second hook is provided at the right end of the fixing part, the second hook is located on the end face of the second connecting part, and the fasteners are arranged on the end face of the fixing part.

[0007] Compared with the prior art, the beneficial effects of the present utility model are as follows: In the processing cartridge proposed by the present utility model, by separating the gear end cover and the chip holder and fixing the chip holder to the gear end cover by fasteners, the chip holder can be installed or disassembled independently of the gear end cover. This split structure not only simplifies the assembly process but also improves the convenience of later maintenance. For example, when the chip holder fails or needs to be replaced, it can be replaced without disassembling the gear end cover, thereby reducing the maintenance cost. The structural design of the fixing part and the connecting part on the chip holder enables the chip holder to be docked with the processing cartridge body in a more precise manner. The setting of the connecting part facilitates the preliminary positioning between the chip holder and the processing cartridge, while the fixing part ensures the stability of the chip holder after final installation. This zoned design not only improves the installation accuracy of the chip but also enhances the connection strength between it and the processing cartridge body. At the same time, the design of hooks in different directions not only provides a preliminary clamping function but also ensures the balance of the chip holder during installation through its symmetrical layout, avoiding installation deviation or structural deformation caused by uneven stress. Moreover, by independently forming the gear end cover and the chip holder and then assembling them, not only are the assembly steps reduced, but the overall manufacturing efficiency is also improved.

[0008] For the above-mentioned processing cartridge, the fasteners are two pins, a fixing hole is provided at the center of the two pins, the two pins are symmetrically arranged with the fixing hole as the center, and the diameters of the two pins are smaller than the diameter of the fixing hole.

[0009] For the above-mentioned processing cartridge, a "C"-shaped first through slot is provided above the first hook.

[0010] For the above-mentioned processing cartridge, a closed second through slot is provided between the fixing hole and the first hook, and the shape of the second through slot is square.

[0011] For the above-mentioned processing cartridge, protruding clamping platforms are respectively provided on the first connecting part and the second connecting part, and the height of the clamping platforms is the same as the height of the pins.

[0012] The aforementioned processing box also includes a connecting plate on the first connecting part, and the card holders are symmetrically arranged front and back with the connecting plate as the center.

[0013] The aforementioned processing box has a first fixing groove and a second fixing groove on the rear end face of the chip holder. The first fixing groove has a step inside, and the second fixing groove has an open structure.

[0014] The aforementioned processing box has a third through slot in the second fixing groove, and the third through slot is located at the bottom of the second hook.

[0015] The aforementioned processing box has a first abutment and a second abutment horizontally arranged on the upper part of the gear end cover, and the locking platform can be locked onto the first abutment and the second abutment.

[0016] In the aforementioned processing box, pin holes are provided below the first abutment portion and the second abutment portion, and the pins can be fixed in the pin holes. A connecting hole is provided between the two pin holes, and the diameter of the connecting hole is equal to the diameter of the fixing hole. Attached Figure Description

Detailed Implementation

[0022] The embodiments of this utility model are described in detail below, with reference to Figures 1 to 4This utility model provides a processing box with a novel side cover, including: a gear end cover 1000 and a chip holder 2000. The gear end cover 1000 is integrally formed with the processing box body 3000. The chip holder 2000 is fixed to the gear end cover 1000 by fasteners 4000. The chip holder 2000 is provided with a fixing part 2100 and a connecting part 2200. The connecting part 2200 includes a first connecting part 2210 and a second connecting part 2220. The first connecting part 2210 is provided with a horizontally placed first hook 2211 in the center. The first connecting part 2210 is symmetrically arranged with the first hook 2211 as the center. The second connecting part 2220 is located on the right side of the first connecting part 2210. The right end of the fixing part 2100 is provided with a vertically placed second hook 2110. The second hook 2110 is located on the end face of the second connecting part 2220. The fasteners 4000 are provided on the end face of the fixing part 2100. The processing box 3000 proposed in this utility model separates the gear end cover 1000 from the chip holder 2000. The chip holder 2000 is fixed to the gear end cover 1000 by fasteners 4000, allowing the chip holder 2000 to be installed or removed independently of the gear end cover 1000. This separate structure not only simplifies the assembly process but also improves the convenience of later maintenance. For example, when the chip holder 2000 malfunctions or needs to be replaced, it can be replaced without disassembling the gear end cover 1000, thereby reducing maintenance costs. The structural design of the fixing part 2100 and the connecting part 2200 on the chip holder 2000 allows the chip holder 2000 to dock with the processing box body 3000 more precisely. The connecting part 2200 facilitates the initial positioning between the chip holder 2000 and the processing box 3000, while the fixing part 2100 ensures the stability of the chip holder 2000 after final installation. This regional design not only improves the installation accuracy of the chip but also enhances the connection strength between it and the processing box body 3000. At the same time, the design of the hooks in different directions not only provides a preliminary snap-fit ​​function but also ensures the balance of the chip holder 2000 during installation through its symmetrical layout, avoiding installation misalignment or structural deformation caused by uneven force. Moreover, by molding the gear end cap 1000 and the chip holder 2000 independently before assembly, not only are assembly steps reduced but overall manufacturing efficiency is also improved.

[0023] Furthermore, the fastener 4000 is two pins. A fixing hole 5000 is provided in the center of the two pins. The two pins are symmetrically arranged with the fixing hole 5000 as the center, and the diameters of the two pins are smaller than the diameter of the fixing hole 5000. The design of the two pins symmetrically arranged on both sides of the fixing hole 5000 enables the fastener 4000 to maintain good symmetry and balance during the installation process. This symmetrical layout not only improves the connection stability between the chip holder 2000 and the gear end cover 1000, but also reduces the installation deviation or structural deformation caused by uneven stress. Of course, the present application does not limit the specific structure of the fixing hole 5000. Refer to Figure 3 , preferably, there is a closed second through slot 2213 between the fixing hole 5000 and the first hook 2211, and the shape of the second through slot 2213 is square. The fixing hole 5000 is located inside the second through slot 2213, and the upper and lower wall surfaces of the fixing hole 5000 are integrally formed with the inner wall surface of the second through slot 2213, so that the chip holder 2,000 forms a continuous and unbroken structural connection in this area. This integrated structure design significantly enhances the structural strength and rigidity of the chip holder 2000 in the stress area and can effectively resist deformation and stress concentration under external forces. Further, a "C"-shaped first through slot 2212 is provided above the first hook 2211. The design of the "C"-shaped first through slot 2212 provides an additional clamping function for the first hook 2211. The opening direction of the slot is consistent with the installation direction of the chip holder 2000, so that during the installation process, the chip holder 2000 can be initially clamped with the corresponding structure (such as a buckle or a protrusion) on the processing box body 3000 through this slot. This clamping function not only improves the convenience of installation, but also enhances the guiding effect of the chip holder 2000 during the installation process and avoids structural damage caused by improper installation or deviation. Secondly, the design of the through slot enables the first hook 2,211 to disperse stress through the structural characteristics of the slot when受力. This stress dispersion mechanism effectively reduces the risk of the first hook 2211 breaking or deforming during use, thereby improving the service life and reliability of the chip holder 2000. In addition, the "C"-shaped slot also has a certain guiding effect visually, which is convenient for the operator to quickly identify the installation direction during the assembly process and reduces the rework rate caused by installation errors. This design has significant advantages in mass production, can improve the assembly efficiency and reduce the production cost.

[0024] Further, refer to Figure 1The first connecting portion 2210 and the second connecting portion 2220 each have a protruding locking platform 2230, the height of which is the same as the height of the pin. The first connecting portion 2210 also has a connecting plate 2240, and the locking platforms 2230 are symmetrically arranged front and back around the connecting plate 2240. The locking platform 2230 provides an additional support point for the assembly between the chip holder 2000 and the gear end cover 1000. As a protruding structure, the locking platform 2230, with its height matching that of the pin, means that when the chip holder 2000 is installed onto the gear end cover 1000, the locking platform 2230 can simultaneously contact and bear force with the pin, thus achieving multi-point support. This multi-point support structure not only improves the stability of the chip holder 2000 after installation but also effectively prevents tilting or displacement caused by uneven local force, improving assembly accuracy. Simultaneously, the locking platform 2230 enhances the friction and fitting between the chip holder 2000 and the gear end cover 1000. A certain frictional force is formed between the contact surfaces of the card holder 2230 and the gear end cover 1000. This frictional force not only helps prevent the chip holder 2000 from loosening during use, but also acts as a buffer when subjected to external vibration or impact, thereby improving the vibration resistance of the chip holder 2000. The connecting plate 2240 enhances the overall structural strength of the first connecting part 2210. As a reinforcing structure on the first connecting part 2210, the connecting plate 2240 not only improves the rigidity of this area, but also provides structural support for the symmetrical distribution of the card holder 2230. This reinforcement makes the first connecting part 2210 less prone to bending or deformation when subjected to external forces, thereby improving the durability and stability of the chip holder 2000 during use. Of course, this utility model does not limit the specific shape of the card holder 2230 and the connecting plate 2240, referring to... Figure 1 The card platform 2230 has a horizontal plane, and the front and rear card platforms 2230 are symmetrical about the connecting plate 2240.

[0025] Furthermore, referring to Figure 4The chip holder 2000 has a first fixing groove 2300 and a second fixing groove 2400 on its rear end face. The first fixing groove 2300 has a step 2310 inside, while the second fixing groove 2400 has an open structure. The design of the step 2310 in the first fixing groove 2300 allows for multi-level positioning of the chip holder 2000 during installation. The step 2310 not only provides more precise installation guidance for the chip holder 2000 but also enhances the stability of its fit with the processing box body 3000. This multi-level positioning mechanism effectively prevents the chip holder 2000 from shifting or tilting during installation, improving assembly accuracy. Of course, this utility model does not limit the specific shape of the first fixing groove 2300. Preferably, the first fixing groove 2300 is trapezoidal, and the second fixing groove 2400 is polygonal. Furthermore, the second fixing groove 2400 is provided with a third through groove 2410, located at the bottom of the second hook 2110. The third through groove 2410 provides additional structural support for the second hook 2110. Located at the bottom of the second hook 2110, this groove allows the second hook 2110 to distribute stress evenly throughout the structure of the second fixing groove 2400 when under stress, thereby improving the bending resistance and structural strength of the second hook 2110. This design effectively prevents the second hook 2110 from breaking or deforming during use, extending the service life of the chip holder 2000. Furthermore, referring to… Figure 2The upper part of the gear end cover 1000 has a horizontally arranged first abutment portion 1100 and abutment portion 1200, and the locking platform 2230 can engage with the first abutment portion 1100 and the second abutment portion 1200. The arrangement of the first abutment portion 1100 and the second abutment portion 1200 provides a clear limiting structure for the chip holder 2000. These two abutment portions serve as positioning references during the installation of the chip holder 2000, allowing the chip holder 2000 to engage with it via the locking platform 2230 during installation, thereby achieving precise alignment and limiting. This limiting mechanism effectively prevents the chip holder 2000 from shifting or tilting during installation, improving assembly accuracy. Of course, this utility model does not limit the specific structure of the first abutment portion 1100 and the second abutment portion 1200; preferably, the first abutment portion 1100 and the second abutment portion 1200 have flat surfaces. Furthermore, a pin hole 1300 is provided below the first abutment portion 1100 and the second abutment portion 1200, allowing the pin to be fixed in the pin hole 1300. A connecting hole 1400 is provided between the two pin holes 1300, and the diameter of the connecting hole 1400 is equal to the diameter of the fixing hole 5000. The pin hole 1300 provides a precise positioning reference for pin installation. The connecting hole 1400 between the two pin holes 1300 has the same diameter as the fixing hole 5000, enabling the pin to form a good centering fit with the connecting hole 1400 during insertion, thereby improving assembly accuracy and connection stability. This structural design effectively prevents connection loosening or signal transmission interruption caused by installation deviation. The design that the connecting hole 1400 has the same diameter as the fixing hole 5000 allows the pin to be subjected to synchronous force during insertion. This structural design not only improves the uniformity of the connection but also avoids local stress concentration caused by uneven force, thereby improving the fatigue resistance and service life of the chip frame 2000. Furthermore, the combination of the pin hole 1300 and the connecting hole 1400 facilitates the disassembly and replacement of the chip holder 2000. During maintenance, the chip holder 2000 can be quickly detached simply by pulling out the pin, thereby improving maintenance efficiency and reducing repair costs.
