Description

Technical Field

[0001] This utility model relates to the field of printing consumables, and in particular to an integrated isolation and protection structure for toner cartridges. Background Technology

[0002] Currently, most toner cartridges on the market use two separate materials for their protective covers and isolation clips; that is, the protective cover is a separate protective cover, and the isolation clip is a separate isolation clip, meaning the production materials are divided into two types. This increases costs related to storage, transportation, production, and distribution.

[0003] Ordinary isolation buckles are all physical isolation methods that forcibly pry open or push open the developing roller and charging roller inside the drum to perform the isolation function. In order to facilitate removal before use, various ergonomic pull rings and handles need to be designed on one end of the isolation buckle. Therefore, most isolation buckles are made relatively large, increasing storage space costs and material costs.

[0004] Therefore, it is necessary to provide a structure that can combine a protective cover and an isolation buckle. Utility Model Content

[0005] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to provide a structure that integrates the protective cover and the isolation buckle.

[0006] An integrated isolation and protection structure for a toner cartridge includes a protective cover for structural protection when mounted on the toner cartridge, and an isolation buckle for isolating the developing roller and the charging roller. The protective cover and the isolation buckle are integrally connected. The isolation buckle is provided with several bending grooves for easy bending. The protective cover is provided with a handle for easy lifting. The protective cover is provided with fasteners for connecting to the toner cartridge.

[0007] Furthermore, the protective cover and isolation buckle in this utility model are integrally molded by injection molding.

[0008] Furthermore, the present invention includes two isolation buckles, which are respectively located on the left and right sides of the front end of the protective cover.

[0009] Furthermore, the present invention has three bending grooves on the isolation buckle, and the isolation buckle can be bent through the bending grooves.

[0010] Furthermore, the fastener in this utility model includes a front fastener and a rear fastener, which correspond to the front and rear frames of the toner cartridge, respectively.

[0011] Furthermore, the handle in this utility model is located in the middle of the rear side of the protective cover.

[0012] In summary, the advantages of this utility model over the prior art are: This utility model combines the protective cover and the isolation buckle into one structure. The isolation buckle is designed as an extended pin that adapts to the shape of the corresponding toner cartridge and can be bent to a fixed length. This eliminates the need for the ergonomic pull ring and handle of the traditional isolation buckle, and uses the entire protective cover as the pull ring and handle of the isolation buckle. The overall structure is simpler and reduces storage, transportation, production and distribution costs. Attached Figure Description

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 4 The present invention preferably provides an integrated isolation and protection structure for a toner cartridge, including a protective cover 1 for structural protection when mounted on the toner cartridge, and an isolation buckle 2 for isolating the developing roller and charging roller. The protective cover 1 and the isolation buckle 2 are integrally connected. The isolation buckle 2 is provided with several bending grooves 21 for easy bending. The protective cover 1 is provided with a handle 3 for easy lifting, and a fastener 4 for connecting to the toner cartridge is provided on the protective cover 1. The large protective cover also serves as a pull ring and handle for removing the isolation buckle, which is more ergonomic and easier to use. It allows the entire palm to grasp the protective cover to remove the isolation buckle, rather than using only one finger to hold the pull ring or handle. During installation, simply install the protective cover, bend the extended pin part, insert it into the corresponding pin hole on the toner cartridge, and press it all the way down. At the same time, the isolation buckle pin also serves as a fixing device for the protective cover, making it less likely to fall off. The bending groove, located on the upper side of the isolation buckle, allows the buckle to bend along it. The buckle itself is made of plastic and has a certain degree of bending capability, allowing it to be easily inserted into the corresponding pin hole on the toner cartridge. The fastener is used for mounting and connecting the protective cover to the toner cartridge.

[0015] In this invention, the protective cover 1 and the isolation buckle 2 are integrally molded by injection molding. This integral molding reduces mold opening costs and saves on structural costs.

[0016] In this utility model, there are two isolation buckles 2, which are respectively located on the left and right sides of the front end of the protective cover 1.

[0017] In this invention, three bending grooves 21 are provided on the isolation buckle 2, allowing the isolation buckle 2 to be bent through the positions of the bending grooves 21. The bending grooves are arc-shaped concave surfaces, enabling the isolation buckle to be bent or folded along them.

[0018] The fastener 4 described in this utility model includes a front fastener 41 and a rear fastener 42, which correspond to the front and rear frames of the toner cartridge, respectively. Traditional toner cartridges are divided into two frames, therefore the front and rear fasteners connect to the two frames respectively.

[0019] In this utility model, the handle 3 is located in the middle of the rear side of the protective cover 1.

[0020] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
