Description

Technical Field

[0001] This utility model relates to the field of anti-collision photosensitive drum technology, specifically to an anti-collision photosensitive drum with a protective cover. Background Technology

[0002] Laser printers primarily rely on the core component, the toner cartridge, to achieve their printing function. The core component of the toner cartridge is the photosensitive drum. After one or two cycles of use, the coating on the aluminum tube of most photosensitive drums becomes unusable due to mechanical wear and photoelectric fatigue. Even after several cycles of use, the gears of the photosensitive drum are not significantly different in performance from new gears.

[0003] According to patent document CN101620404A, a method for modifying a photosensitive drum into another type of photosensitive drum is disclosed, comprising the following steps: A. Removing a drum gear one installed at one end of the drum body of one type of photosensitive drum and a component one installed at the other end of the drum body; B. Installing a drum gear two and a component two suitable for another type of photosensitive drum at both ends of the drum body respectively. A preferred method is that in step A, a push rod is used to push out component one or drum gear one through the hole in drum gear one or component one.

[0004] Currently, traditional photosensitive drums with protective covers to prevent impact damage are prone to damage during disassembly because the photosensitive drum, gears, and aluminum tube are riveted together, making them unrecyclable. If the photosensitive drum gears and aluminum tubes are scrapped, it will cause greater waste of resources and environmental pollution. Furthermore, the pins on the photosensitive drum are not elastic and cannot achieve real-time elastic contact with the conductive posts, resulting in low reliability of the electrical connection. Utility Model Content

[0005] The purpose of this utility model is to provide a photosensitive drum with a protective cover to prevent damage during use. This solves the problems mentioned in the background art, where the photosensitive drum, gears, and aluminum tube are riveted together, making it easy to damage the aluminum tube and gears during disassembly and preventing recycling. If the photosensitive drum gears and aluminum tubes are scrapped, it will cause greater waste of resources and environmental pollution. Furthermore, the pins on the photosensitive drum lack elasticity and cannot achieve real-time elastic contact with the conductive posts, resulting in low reliability of the electrical connection.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a photosensitive drum body, a cross block is provided on one side of the photosensitive drum body, a connecting rod is provided on the other side of the cross block, a protective mechanism is sleeved on the outer side wall of the photosensitive drum body, a slot is opened through the other side outer side wall of the photosensitive drum body, a limiting groove is embedded in one side of the photosensitive drum body, and a disassembly and assembly mechanism is detachably connected to one side of the photosensitive drum body.

[0007] The protective mechanism includes a housing, the inner wall of which is sleeved with the outer wall of the photosensitive drum body, a cross groove is provided on one side of the housing, a receiving cavity is provided on the inner wall of the housing, and a protective shell is fixed to the side of the housing away from the cross groove.

[0008] Preferably, one side of the housing is connected through to the outer wall of the cross groove, and the inner wall of the housing is embedded in the outer wall of the storage cavity.

[0009] Preferably, the housing and the protective shell are integrally formed.

[0010] Preferably, one side of the cross block is fixedly connected to one side of the photosensitive drum body, and the other side of the cross block is fixedly connected to one side of the connecting rod.

[0011] Preferably, the disassembly and assembly mechanism includes a gear, one side of which is in close contact with one side of the photosensitive drum body. A spring is provided on one side of the gear, and an insertion end is provided on the other side of the spring. Elastic clips are fixed to the top and bottom of one side of the gear. A sealing ring is fixed to one edge of the insertion end. A collar is slidably connected to the outer wall of the insertion end. Pull rods are fixed to the front and rear ends of one side of the collar. Limiting blocks are fixed around one side of the gear. A reinforcing rib is fixed to the inner wall of the gear on the side away from the spring.

[0012] Preferably, one side of the gear is fixedly connected to one side of the spring, and the other side of the spring is fixedly connected to one side of the outer wall of the insertion end.

[0013] Preferably, the pull rod extends from the side away from the collar via a gear and to one side of the gear.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The protective mechanism effectively buffers and disperses impact forces when the equipment is subjected to external collisions, preventing direct damage to the photosensitive drum body. This extends the lifespan of the photosensitive drum, reduces scrapping due to collisions, and minimizes resource waste and environmental pollution. It also facilitates disassembly and installation, making maintenance and replacement of the photosensitive drum easier and improving the usability of the equipment. Furthermore, the disassembly mechanism makes the connection between the photosensitive drum and gears more flexible, preventing damage to the aluminum tube and gears during disassembly, facilitating recycling and further saving resources. Moreover, the springs and insertion ends in the disassembly mechanism provide elasticity to the pins on the photosensitive drum, enabling real-time elastic contact with the conductive posts, improving the reliability of the electrical connection and ensuring stable operation of the equipment.

[0016] 2. The designed disassembly and assembly mechanism allows for quick and safe separation and assembly of the photosensitive drum body from gears and other components when replacement or maintenance is required. For disassembly, simply operate the lever to slide the collar on the insertion end, causing the elastic clip to deform and release its locking mechanism between the gear and the photosensitive drum body. At this point, under the action of the spring, the insertion end partially disengages from the gear, loosening the connection between the gear and the photosensitive drum body. This allows the gear to be easily removed from the photosensitive drum body. This process avoids the damage to the aluminum tube and gear caused by traditional riveting methods during disassembly, achieving non-destructive disassembly and facilitating easy removal. Recycling and reusing individual components significantly saves resources and reduces environmental pollution caused by component disposal. The assembly mechanism also plays a crucial role during assembly. The gear is aligned with the corresponding position on the photosensitive drum body, and then the pull rod is pushed, causing the collar to slide and compress the spring. Simultaneously, the elastic clip deforms under the pressure of the collar and engages in the gap between the gear and the photosensitive drum body, achieving a secure connection. At this point, the insertion end is fully inserted into the gear under the elastic force of the spring, forming real-time elastic contact with the conductive post, ensuring the reliability of the electrical connection. This assembly method is not only easy to operate but also provides a stable connection, effectively improving the efficiency and stability of the equipment. Attached Figure Description

The protective mechanism 4 includes a housing 41, and the inner side of the housing 41... The outer wall of the housing 41 is sleeved with the outer wall of the photosensitive drum body 1. A cross groove 42 is provided on one side of the housing 41. A receiving cavity 43 is provided on the inner wall of the housing 41. A protective shell 44 is fixedly connected to the side of the housing 41 away from the cross groove 42. One side of the housing 41 is connected through to the outer wall of the cross groove 42. The inner wall of the housing 41 is embedded and connected to the outer wall of the receiving cavity 43. The housing 41 and the protective shell 44 are integrally formed. One side of the cross block 2 is fixedly connected to one side of the photosensitive drum body 1. The other side of the cross block 2 is fixedly connected to one side of the connecting rod 3.

[0024] A cross block 2 is provided on one side of the photosensitive drum body 1, and a connecting rod 3 is firmly connected to the other side of the cross block 2. To enhance the protective effect, a protective mechanism 4 is fitted onto the outer wall of the photosensitive drum body 1. In addition, a slot 5 is opened through the outer wall of the other side of the photosensitive drum body 1, and a limiting groove 6 is embedded and connected on one side of the photosensitive drum body 1 to achieve precise positioning. For convenient maintenance and replacement, a detachable disassembly and assembly mechanism 7 is also provided on one side of the photosensitive drum body 1. Furthermore, the inner wall of the housing 41 is tightly fitted with the outer wall of the photosensitive drum body 1 to ensure the protective effect. A cross groove 42 is provided on one side of the housing 41 for use with the cross block 2. A storage cavity 43 is also provided on the inner wall of the housing 41 for fitting and protecting the photosensitive drum body 1. A protective shell 44 is firmly fixed to the side of the housing 41 away from the cross groove 42 to further enhance the protective function. One side of the housing 41 is connected through to the outer wall of the cross groove 42 to ensure structural stability. The inner wall of the housing 41 and the outer wall of the receiving cavity 43 are connected by an embedded connection to form a whole. The housing 41 and the protective shell 44 are set as an integral structure, which improves the overall stability and durability. In addition, one side of the cross block 2 is fixedly connected to one side of the photosensitive drum body 1 to ensure that the cross block 2 will not loosen. The other side of the cross block 2 is also fixedly connected to one side of the connecting rod 3, which ensures the stability and reliability of the entire device. Through this structure, not only is the photosensitive drum not damaged by collision during use, but the overall performance and service life of the equipment are also greatly improved.

[0025] Please see Figure 1 , Figure 3 and Figure 4 The disassembly and assembly mechanism 7 includes a gear 71. One side of the gear 71 is in close contact with one side of the photosensitive drum body 1. A spring 72 is provided on one side of the gear 71, and an insertion end 73 is provided on the other side of the spring 72. Elastic clips 74 are fixed to the top and bottom of one side of the gear 71. A sealing ring 75 is fixed to one edge of one side of the insertion end 73. A collar 76 is slidably connected to the outer wall of the insertion end 73. A pull rod 77 is fixed to the front and rear ends of one side of the collar 76. Limit blocks 78 are fixed around one side of the gear 71. A reinforcing rib 79 is fixed to the inner wall of the gear 71 away from the spring 72. One side of the gear 71 is fixed to one side of the spring 72. The other side of the spring 72 is fixed to one side of the outer wall of the insertion end 73. The pull rod 77 extends from the side away from the collar 76 through the gear 71 to one side of the gear 71.

[0026] One side of the gear 71 is tightly fitted to the corresponding side of the photosensitive drum body 1 to ensure accurate transmission between them. A spring 72 is installed on this side of the gear 71 to provide necessary elastic support. The other end of the spring 72 is connected to an insertion end 73, which is used for docking with other components. Furthermore, elastic clips 74 are securely connected to the top and bottom of one side of the gear 71. These elastic clips 74 play an important role in positioning and buffering during the mechanism's operation. A sealing ring 75 is fixed to one edge of the insertion end 73 to ensure a tight seal when the insertion end 73 is connected to the photosensitive drum body 1, preventing foreign objects from entering. In addition, the outer wall of the insertion end 73 is slidably connected to a collar 76. Pull rods 77 are securely connected to both ends of one side of the collar 76. These pull rods 77 play a crucial role in pulling and supporting during assembly and disassembly. To ensure the stability of gear 71 during operation, limit blocks 78 are fixed around one side of gear 71, effectively limiting the range of movement of gear 71. Reinforcing ribs 79 are also fixed to the inner wall of gear 71 on the side away from spring 72, enhancing the strength and durability of gear 71. One side of gear 71 is securely connected to one side of spring 72, while the other side of spring 72 is tightly fixed to the outer wall of insertion end 73, ensuring the stability and reliability of the entire mechanism. Finally, the pull rod 77 extends from the side away from collar 76 through gear 71 to one side of gear 71. This arrangement allows the pull rod 77 to drive collar 76 to move flexibly and squeeze elastic card 74, disengaging it from slot 5, thus achieving smooth assembly and disassembly of the mechanism. This structural design, with its seamless cooperation between components, ensures its high efficiency and stability in practical applications.

[0027] Working principle: First, the protective mechanism 4 is sleeved onto the outer wall of the photosensitive drum body 1, so that the inner wall of the housing 41 is tightly fitted with the outer wall of the photosensitive drum body 1. At this time, the cross block 2 and the cross groove 42 on one side of the housing 41 cooperate with each other to achieve precise positioning. The receiving cavity 43 then provides sleeve protection for the photosensitive drum body 1. The protective shell 44 further enhances the protection function of the photosensitive drum body 1, preventing it from being damaged by collisions during use. When disassembly or assembly is required, the pull rod 77 is pulled. The pull rod 77 drives the collar 76 to slide on the outer wall of the insertion end 73. During the sliding process, the collar 76 squeezes the elastic card 74, causing the elastic card 74 to deform and detach. The spring 72 is compressed while the slot 5 is in place. When the elastic card 74 is completely disengaged from the slot 5, the disassembly and assembly mechanism 7 can be removed from the photosensitive drum body 1. During installation, the insertion end 73 of the disassembly and assembly mechanism 7 is aligned with the corresponding position on the photosensitive drum body 1. The pull rod 77 is pushed, causing the collar 76 to slide in the opposite direction. The elastic card 74 returns to its original shape under its own elastic force and is inserted into the slot 5. At the same time, the spring 72 also returns to its original length, providing a certain elastic support to ensure that the disassembly and assembly mechanism 7 is firmly connected to the photosensitive drum body 1. This setting not only facilitates the maintenance and replacement of the photosensitive drum, but also improves the overall performance and service life of the equipment, and reduces resource waste and environmental pollution.

[0028] Then, through the coordinated action of the protective mechanism 4 and the disassembly / removal mechanism 7, and through the arrangement of the housing 41, cross groove 42, storage cavity 43, and protective shell 44, the photosensitive drum body 1 is provided with all-round protection, effectively avoiding damage caused by collisions, thereby extending the service life of the photosensitive drum. At the same time, the disassembly / removal mechanism 7, through the joint cooperation of components such as gear 71, spring 72, insertion end 73, elastic clip 74, sealing ring 75, collar 76, and pull rod 77, makes the disassembly / removal process simple and quick. When maintenance or replacement of the photosensitive drum is required, simply pull gently. Pull rod 77 allows the disassembly mechanism 7 to be detached from the photosensitive drum body 1, making installation equally convenient and quick. This design not only improves work efficiency but also reduces operational difficulty, making it easy to learn. Furthermore, it reduces unnecessary material waste and lowers production costs. At the same time, since components such as the photosensitive drum and gear 71 can be easily disassembled and replaced, resource recycling is achieved, reducing environmental pollution. The above is the working process of the entire device. Any content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
