Adjustable mounting bracket type toner cartridge

Abstract

This utility model discloses an adjustable mounting bracket type toner cartridge, including a mounting bracket, a toner cartridge detachably installed inside the mounting bracket, a toner slot secured to the toner cartridge, and a connector assembly installed inside the toner cartridge. A groove on the toner cartridge restricts the sliding trajectory of the limiting and fixing ring, ensuring that the second sliding push rod drives the connector pin to move smoothly in a straight line, further preventing deviation and ensuring stable spacing between the developing roller and the drum core, and precise alignment of the toner cartridge and printer interface. For self-locking, a third spring continuously applies preload force to the second sliding push rod through the limiting and fixing ring, ensuring a tight fit between the connector pin and the slot of the connecting block, forming a reliable lock. Even under external forces such as printer vibration or handling, it prevents loosening. This integrated guiding and self-locking structure fundamentally solves the deviation and loosening problems of traditional adjustment mechanisms, improving the working stability and printing accuracy of the toner cartridge.

Description

Technical Field

[0001] This utility model relates to the field of toner cartridge technology, specifically to an adjustable mounting bracket type toner cartridge. Background Technology

[0002] Toner cartridges are the core imaging components of laser printers, copiers, and other equipment. Commonly known as "photosensitive drums," they are essentially cylindrical components with a photosensitive coating. Their core function is to precisely transfer toner onto paper through electrostatic adsorption, ultimately forming clear text or images. Adjustable mounting bracket toner cartridges are improved versions of ordinary toner cartridges, with the addition of a movable and adjustable mounting bracket. The key is to solve the problems of poor installation compatibility and difficulty in calibrating imaging gaps in traditional toner cartridges through the multi-dimensional adjustment function of the bracket.

[0003] In existing technologies, the adjustment mechanism lacks integrated guiding and self-locking functions, often employing simple threaded or sliding fits. During adjustment, the bracket is prone to shifting in a non-preset direction, and there is no reliable locking structure after adjustment. It is easily loosened by external forces such as printer vibration and handling, leading to misalignment of the developing roller and drum core, and misalignment of the toner cartridge and printer interface. The connection between the bracket, the toner cartridge body, and the printer mounting position is a rigid fit without a buffer positioning structure. This not only exacerbates vibration transmission and makes the adjusted position more prone to failure, but also causes uneven stress due to connection gaps. Long-term use will cause bracket deformation and wear of the mounting holes, further amplifying the adjustment accuracy error. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable mounting bracket type toner cartridge to solve the problems mentioned in the background art, such as the lack of integrated guiding and self-locking functions of the adjustment mechanism, the use of simple thread or sliding fit, the bracket being prone to shifting in a non-preset direction during adjustment, and the lack of a reliable locking structure after adjustment, which makes it easy to become loose due to external forces such as printer vibration and handling.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable mounting bracket type toner cartridge, including a mounting bracket, a toner cartridge detachably mounted inside the mounting bracket, a toner slot mounted on the toner cartridge, a plug-in assembly mounted inside the toner cartridge, a buffer assembly mounted inside the mounting bracket, a connecting block mounted on the plug-in assembly, a fixed mounting block fixedly connected to the toner cartridge, a second sliding push rod slidably connected to the fixed mounting block, a limiting ring fixedly connected to the second sliding push rod, a third spring fixedly connected between the limiting ring and the toner cartridge, a push plate fixedly connected to the second sliding push rod, a push post fixedly connected to the second sliding push rod, a push button mounted at one end of the push post, and a plug-in post fixedly connected to the push plate. The plug-in post is inserted into the connecting block, the connecting block is inserted into the toner cartridge, and the plug-in assembly drives the connecting block to move along a preset direction.

[0006] In the preferred embodiment of this technical solution, the connecting block has a slot at the corresponding position of the plug-in post, and the plug-in post is inserted into the slot.

[0007] Based on the preferred embodiment of this technical solution, the toner cartridge has a groove at the corresponding position of the limiting and fixing ring, and the limiting and fixing ring slides inside the groove.

[0008] In a preferred embodiment of this technical solution, the plug-in assembly includes a sliding limit rod slidably connected inside the toner cartridge, an installation limit ring fixedly connected to the sliding limit rod, a fourth spring fixedly connected between the toner cartridge and the installation limit ring, a toggle block fixedly connected to the sliding limit rod, and a toggle button fixedly connected to the toggle block. The connecting plug is fixedly connected to one end of the sliding limit rod, and the fourth spring pushes the connecting plug to move along a preset direction.

[0009] In the preferred embodiment of this technical solution, there are two sliding limit rods, and the two sliding limit rods are symmetrically slidably connected inside the toner cartridge.

[0010] In the preferred embodiment of this technical solution, the toner cartridge has a groove at the corresponding position of the toggle block, and the toggle block slides inside the groove.

[0011] According to the preferred embodiment of this technical solution, the buffer assembly includes a fixed limiting rod fixedly connected inside the toner cartridge, a sliding support seat slidably connected to the fixed limiting rod, a first spring fixedly connected between the sliding support seat and the toner cartridge, a first sliding push rod slidably connected inside the toner cartridge, a limiting push block fixedly connected to one end of the first sliding push rod, a second spring fixedly connected between the limiting push block and the toner cartridge, and a fixed insert block fixedly connected to the bottom of the toner cartridge. The first spring pushes the sliding support seat to move in a preset direction.

[0012] Based on the preferred embodiment of this technical solution, two fixed limiting rods are provided, and the two fixed limiting rods are symmetrically fixedly connected inside the mounting frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The slots of the connecting blocks and the insertion pins form a precise fit, providing clear guidance for the insertion process and preventing deviation along non-preset directions during adjustment. The sliding groove on the toner cartridge limits the sliding trajectory of the limiting and fixing ring, ensuring that the second sliding push rod drives the insertion pin to move smoothly in a straight line, further eliminating deviation and ensuring stable spacing between the developing roller and the drum core, and precise alignment between the toner cartridge and the printer interface. For self-locking, the third spring continuously applies preload force to the second sliding push rod through the limiting and fixing ring, making the insertion pin and the slot of the connecting blocks fit tightly, forming a reliable lock. Even under the influence of external forces such as printer vibration and handling, it can prevent loosening. This integrated guiding and self-locking structure fundamentally solves the deviation and loosening problems of traditional adjustment mechanisms, improving the working stability of the toner cartridge and printing accuracy.

[0014] 2. The sliding support seat, guided by the fixed limiting rod, works in conjunction with the first spring to efficiently absorb longitudinal vibration. The first sliding push rod, the limiting push block, and the second spring work together to offset lateral impact. This bidirectional buffer structure significantly reduces vibration transmission, preventing adjustment failure due to vibration. The positioning function of the fixed insert, combined with the fitting design of each component, completely eliminates the connection gap between the bracket and the toner cartridge / printer mounting position, ensuring even force distribution and preventing bracket deformation and mounting hole wear caused by localized stress concentration. The elastic preload of the spring maintains a stable fit at the connection points, reducing the amplification of adjustment accuracy errors during long-term use. This extends the service life of the components and bracket, continuously ensures the spacing accuracy between the developing roller and the drum core, and guarantees stable print quality, fundamentally improving the defects of rigid connections from a structural perspective.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 This utility model provides an embodiment of an adjustable mounting bracket type toner cartridge: it includes a mounting bracket 1, a toner cartridge 2 detachably mounted inside the mounting bracket 1, a toner tray 3 snapped onto the toner cartridge 2, a plug-in assembly mounted inside the toner cartridge 2, a buffer assembly mounted inside the mounting bracket 1, a connecting plug 901 mounted on the plug-in assembly, a fixed mounting block 902 fixedly connected to the toner cartridge 2, a second sliding push rod 903 slidably connected to the fixed mounting block 902, and a component fixedly connected to the second sliding push rod 903. The system comprises a limiting and fixing ring 904, a third spring 905 fixedly connected between the limiting and fixing ring 904 and the toner cartridge 2, a push plate 906 fixedly connected to the second sliding push rod 903, a push column 908 fixedly connected to the second sliding push rod 903, a push button 909 installed at one end of the push column 908, and a plug-in column 907 fixedly connected to the push plate 906. The plug-in column 907 is plugged into a connecting plug 901, which is inserted into the inside of the toner cartridge 2. The plug-in assembly drives the connecting plug 901 to move along a preset direction. Through the plug-in engagement of the connecting plug 901 and the plug-in column 907, precise positioning and rapid connection of the internal components of the toner cartridge 2 are achieved, avoiding assembly deviations that affect imaging accuracy. The third spring 905 applies a continuous preload to the second sliding push rod 903 through the limiting and fixing ring 904, ensuring that the plug-in column 907 and the connecting plug 901 are stably fitted together, preventing loosening due to vibration during use.

[0019] Please see Figure 3A further solution based on this embodiment is as follows: the connecting plug 901 has a slot at the corresponding position of the plug post 907, and the plug post 907 is inserted into the slot. The precise matching of the slot on the connecting plug 901 and the plug post 907 provides clear guidance for their insertion, ensuring rapid alignment during the insertion process and avoiding component wear caused by misalignment.

[0020] Please see Figure 3 A further solution based on this embodiment is as follows: A groove is provided on the drum cartridge 2 at the corresponding position of the limiting and fixing ring 904, and the limiting and fixing ring 904 slides inside the groove. The groove on the drum cartridge 2 strictly limits the sliding trajectory of the limiting and fixing ring 904, ensuring that the limiting and fixing ring 904 drives the second sliding push rod 903 to move smoothly along a preset direction, avoiding misalignment between the insertion post 907 and the connecting block 901 due to offset; the cooperation between the groove and the limiting and fixing ring 904 also disperses the force on the second sliding push rod 903, reducing local wear and extending the service life of the components.

[0021] Please see Figure 2 A further embodiment of this solution is as follows: the plug-in assembly includes a sliding limiting rod 910 slidably connected inside the toner cartridge 2, an installation limiting ring 911 fixedly connected to the sliding limiting rod 910, a fourth spring 913 fixedly connected between the toner cartridge 2 and the installation limiting ring 911, a toggle block 914 fixedly connected to the sliding limiting rod 910, and a toggle button 915 fixedly connected to the toggle block 914. The connecting plug 901 is fixedly connected to one end of the sliding limiting rod 910, and the fourth spring 913 pushes the connecting plug 901 to move along a preset direction. Through the continuous pushing force of the fourth spring 913 on the installation limiting ring 911, the sliding limiting rod 910 automatically drives the connecting plug 901 to fit tightly with the plug-in post 907, realizing the automatic reset and locking of the plug-in structure without manual reinforcement, improving the ease of operation; the sliding limiting rod 910 provides stable guidance for the movement of the connecting plug 901, preventing deviation.

[0022] Please see Figure 2 A further solution based on this embodiment is as follows: Two sliding limit rods 910 are provided, and the two sliding limit rods 910 are symmetrically slidably connected inside the toner cartridge 2. The two symmetrically distributed sliding limit rods 910 synchronously drive the connecting plug 901, so that the two ends of the connecting plug 901 are subjected to balanced force, avoiding tilting or jamming caused by unilateral force, ensuring uniform contact between the contact surface of the connecting plug 901 and the plug post 907, and improving the connection stability.

[0023] Please see Figure 2A further solution based on this embodiment is as follows: the toner cartridge 2 has a groove at the corresponding position of the actuating block 914, and the actuating block 914 slides inside the groove. The groove on the toner cartridge 2 guides and limits the movement of the actuating block 914, ensuring that the actuating block 914 drives the sliding limit rod 910 to move smoothly in a straight line, avoiding adjustment jamming or component interference caused by deviation.

[0024] Please see Figure 4-5 A further embodiment of this solution includes: a buffer assembly comprising a fixed limiting rod 801 fixedly connected inside the drum cartridge 2, a sliding support 802 slidably connected to the fixed limiting rod 801, a first spring 803 fixedly connected between the sliding support 802 and the drum cartridge 2, a first sliding push rod 805 slidably connected inside the drum cartridge 2, a limiting push block 806 fixedly connected to one end of the first sliding push rod 805, a second spring 807 fixedly connected between the limiting push block 806 and the drum cartridge 2, and a fixed insert block 808 fixedly connected to the bottom of the drum cartridge 2. The first spring 803 pushes the sliding support 802 to move in a preset direction. Through the elastic extension and contraction of the first spring 803, the sliding support 802 slides flexibly on the fixed limiting rod 801, which can absorb the longitudinal vibration generated during printer operation, reduce the rigid collision between the drum cartridge 2 and the mounting bracket 1, and protect the internal photosensitive drum, developing roller, and other precision components.

[0025] Please see Figure 4-5 A further solution based on this embodiment is as follows: two fixed limiting rods 801 are provided, and the two fixed limiting rods 801 are symmetrically fixedly connected inside the mounting bracket 1. The two symmetrically distributed fixed limiting rods 801 form bidirectional support for the sliding support seat 802, ensuring that the sliding support seat 802 moves smoothly along a straight line during the buffering process, avoiding tilting or jamming caused by insufficient support on one side, and ensuring the uniform action of the elastic force of the first spring 803.

[0026] Working principle: The toner cartridge 2 is embedded into the mounting bracket 1. The bottom fixing block 808 first completes the initial positioning, and the buffer assembly is activated simultaneously: the first spring 803 pushes the sliding support 802 to fit against the mounting surface along the fixed limit rod 801, and the second spring 807 drives the first sliding push rod 805 to move the limit push block 806 to tighten, forming a longitudinal and lateral bidirectional buffer to reduce installation collisions. Then the plug-in assembly automatically locks: the fourth spring 913 pushes the mounting limit ring 911, which moves the sliding limit rod 910 and the connecting plug 901, so that the slot of the connecting plug 901 aligns with the plug post 907; at the same time, the third spring 905 pushes the second sliding push rod 903 through the limit fixing ring 904, which drives the push plate. The insertion post 907 on 906 is inserted into the slot to achieve precise locking between the toner cartridge 2 and the mounting bracket 1, preventing loosening during operation. During operation, the vibration generated by the printer is absorbed by the buffer assembly: longitudinal vibration is offset by the compression of the first spring 803 by the sliding support seat 802, and lateral vibration is buffered by the compression of the second spring 807 by the limit push block 806, protecting internal components such as the photosensitive drum and developing roller. During maintenance, pressing the button 909 drives the push post 908, causing the push plate 906 to pull the insertion post 907 out of the slot; then moving the toggle button 915 pulls the sliding limit rod 910 through the toggle block 914, and the connecting block 901 separates synchronously, allowing the toner cartridge 2 to be removed for toner replacement or maintenance. The operation is convenient and efficient.
