Description

Technical Field

[0001] This utility model relates to the field of toner cartridge technology, specifically to a toner cartridge separation structure. Background Technology

[0002] In the field of laser printing, toner cartridges and drum units are core consumables, and their detachable design has become mainstream. This design allows users to replace the toner cartridge separately when the toner runs out, without discarding the still-usable drum unit, thus offering both economic and environmental benefits. The key to this design lies in the need for a stable and reliable connection and separation structure.

[0003] Most commonly seen toner cartridge and drum cartridge separation structures on the market employ a dual-sided linkage locking mechanism. Specifically, a locking element (such as a button or lever) is located on both the left and right sides of the drum body, and the two locking elements are rigidly connected by a long rod running through the inside of the drum. When the user operates the locking element on either side, the long rod causes the locking element on the other side to move synchronously, thus unlocking both sides simultaneously to allow the toner cartridge to be removed.

[0004] However, this traditional double-sided linkage structure has obvious inherent defects. First, it has a large number of parts, including two locking components and a long rod, which not only increases mold and raw material costs but also makes the assembly process more complex and reduces production efficiency. Second, the slender connecting rod is prone to slight bending or deformation under long-term use or improper external force. Once deformed, it will cause the locking components on both sides to move asynchronously, resulting in problems such as unilateral jamming, poor unlocking, or insecure locking, which seriously affects the reliability and service life of the separation structure. Utility Model Content

[0005] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a reasonably designed toner cartridge separation structure that can solve the aforementioned defects.

[0006] To achieve the above objectives, the utility model provides the following technical solution: it includes a toner cartridge body, a toner box is provided at the bottom of the toner cartridge body, a protective shell is provided on one side of the toner cartridge body, and a locking component is provided inside the protective shell.

[0007] Preferably, the protective shell has a movable groove, and the locking member is movably disposed in the movable groove.

[0008] Preferably, the bottom of the toner cartridge has a mating groove, and one end of the locking member is inserted into the mating groove.

[0009] The beneficial effects of adopting the above structure are: This invention innovates the traditional double-sided locking structure into a single-sided independent locking structure, directly eliminating a locking component and several other parts such as the long rod connecting the two. The reduction in the number of parts simplifies the structure, greatly optimizes the assembly process, reduces assembly steps and time, and improves production efficiency. As a result, it can generate considerable economic benefits in mass production, while also reducing production costs.

[0010] This invention eliminates the connecting rod, fundamentally avoiding the risk of bending, deformation, or even jamming that may occur due to long-term stress or accidental impact on the connecting rod. The independent locking component has a simple structure, a clear movement trajectory, and a better stress state, thus providing a more stable and durable locking force. Attached Figure Description

[0013] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0014] like Figs. 1-2 As shown, the present invention proposes a toner cartridge separation structure, which mainly consists of a toner cartridge body 1, a toner cartridge 5, a protective shell 2, and a locking component 4. The toner cartridge 5 is detachably installed at the bottom of the drum body 1. A protective shell 2 is fixedly installed on one side of the drum body 1. The protective shell 2 not only protects the internal structure, but also has a movable groove 3 processed on its inner wall. The locking component 4 is an independent slider structure, which is assembled in the movable groove 3 inside the protective shell 2 and can slide back and forth along the groove within a certain range. A spring is usually provided between the locking component 4 and the groove wall of the movable groove 3 to provide a preload force for the locking component 4 toward the toner cartridge 5. At the bottom of the side wall of the toner cartridge 5, corresponding to the position of the locking component 4, a mating groove 6 is provided.

[0015] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of the utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
