Description

Technical Field

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

[0002] The drum unit housing is a component of the toner cartridge in a laser printer or copier. The toner cartridge is a photosensitive element made of photoconductive material used for imaging during the electrostatic copying process. The drum unit housing protects and supports the entire drum unit structure.

[0003] In order to prevent the entire toner cartridge from becoming loose when assembling, most existing toner cartridge shells are connected and fixed with bolts to the front and rear shells. Although this can increase the stability of the entire front and rear shells, it is very cumbersome when replacing the internal toner cartridge body, making it inconvenient to quickly assemble and disassemble the front and rear shells. Utility Model Content

[0004] The purpose of this invention is to provide a modular toner cartridge shell to solve the problem mentioned in the background art that the currently used toner cartridge shells are inconvenient to assemble quickly from the front shell to the rear shell.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined toner cartridge shell, comprising: a front shell and a toner cartridge body, a rear shell connected to one side of the front shell, a rubber stopper connected to the end face of the front shell through a filling port, and the toner cartridge body installed between the front shell and the rear shell;

[0006] One end of the front shell passes through the rear shell and is connected to a mounting block. Both ends of the mounting block are inserted with locking blocks. One end of the locking block is connected to a first rotating block. The top of the first rotating block is connected to a fixing frame via a rotating shaft.

[0007] Preferably, a top rod is connected through the middle of the fixed frame, and a movable spring is connected between the fixed frame and the first rotating block.

[0008] Preferably, a collar is installed on one side of the fixing frame, the collar is installed on one side of the rear shell, and the fixing frame and the collar are an integrated structure.

[0009] Preferably, one end of the rubber plug is connected to an installation ring, and a plug is installed on one side of the installation ring. One end of the plug is inserted into a limit block through a groove.

[0010] Preferably, a second rotating block is installed on one side of the limiting block, and a wedge-shaped block is provided on the top of the second rotating block.

[0011] Preferably, a pressure rod penetrating the front shell is provided on one side of the wedge block, and a telescopic spring is connected between the second rotating block and the groove of the front shell.

[0012] Preferably, a return spring is installed inside the front housing via a groove, and a telescopic block is provided on one side of the return spring.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this combined toner cartridge shell, the front shell and the rear shell can be connected and combined, and the mounting block at one end of the front shell can be moved into the collar at one end of the rear shell. At the same time, the locking block is squeezed, causing the locking block to rotate through the first rotating block. When the mounting block is fully engaged with the inside of the collar, the movable spring will drive the first rotating block to reset and rotate in the opposite direction, rotating the locking block into the groove of the mounting block. The front shell and the rear shell can be quickly assembled and fixed by the locking block and the mounting block. Conversely, the toner cartridge body in the front shell and the rear shell can be quickly replaced. This is the characteristic of the use of this combined toner cartridge shell.

[0014] 1. In use, the front and rear shells of this modular toner cartridge can be connected according to requirements. The first rotating block and the movable spring work together to make the locking block engage with the groove of the mounting block, so that the front and rear shells can be quickly assembled and fixed.

[0015] 2. In use, the pressure rod can be pressed into the toner compartment of the front shell according to the user's needs. This causes the pressure rod to press the second rotating block to rotate through the wedge block. The rotation of the second rotating block will cause the limiting block and the insert block to separate. Then, the reset spring will push the insert block and the mounting ring out from one side of the toner compartment of the front shell through the telescopic block, thus making it convenient for the user to quickly add toner.

[0024] 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.

[0025] Please see Figure 1 This utility model provides a technical solution: a combined toner cartridge shell, including: a front shell 1 and a toner cartridge body 4, a rear shell 2 connected to one side of the front shell 1, a rubber plug 3 connected to the end face of the front shell 1 through a filling port, and the toner cartridge body 4 installed between the front shell 1 and the rear shell 2.

[0026] One end of the front shell 1 passes through the rear shell 2 and is connected to a mounting block 5. Both ends of the mounting block 5 are inserted with locking blocks 6. One end of the locking block 6 is connected to a first rotating block 7. The top of the first rotating block 7 is connected to a fixing frame 8 through a rotating shaft. A top rod 9 is connected through the middle of the fixing frame 8. A movable spring 10 is connected between the fixing frame 8 and the first rotating block 7. A collar 11 is installed on one side of the fixing frame 8. The collar 11 is installed on one side of the rear shell 2. The fixing frame 8 and the collar 11 are an integrated structure. The first rotating block 7 forms a rotating structure with the fixing frame 8 through the rotating shaft.

[0027] In practical implementation, when the entire toner cartridge needs to be assembled, the front shell 1 and the rear shell 2 can be docked, and the end face of the rear shell 2 can be sleeved on the outside of the end face of the front shell 1. At this time, the mounting block 5 at one end of the front shell 1 will move into the collar 11 through the groove of the rear shell 2. During the process of the mounting block 5 moving into the collar 11, it will squeeze the inclined surface of the locking block 6. The locking block 6 will be squeezed and will drive the first rotating block 7 to move upward near the end of the locking block 6 through the rotating shaft, and squeeze the movable spring 10. When the mounting block 5 is completely moved into the inside of the collar 11, the groove at one end of the mounting block 5 will be aligned with the locking block 6. Then the movable spring 10 will be reset and drive the first rotating block 7 to rotate in the opposite direction. At this time, the locking block 6 can be rotated into the groove of the mounting block 5. Due to the limiting effect of the mounting block 5 and the locking block 6, the front shell 1 and the rear shell 2 can be quickly connected and fixed, thus facilitating the connection and fixation of the front shell 1 and the rear shell 2.

[0028] Conversely, simply push the push rod 9 in the opposite direction to the fixed frame 8. The movement of the push rod 9 will cause the bottom arc surface to squeeze the first rotating block 7, causing the first rotating block 7 to drive the locking block 6 to rotate out of the groove of the mounting block 5. Without the locking block 6 limiting the mounting block 5, the front shell 1 and the rear shell 2 can be quickly separated, thus facilitating the replacement of the internal toner cartridge body 4.

[0029] See Figures 1-4 It can be seen that, during use, the front shell 1 and the rear shell 2 can be quickly connected according to the usage requirements, and the mounting block 5 can be slid into the collar 11. The second rotating block 15 on one side of the collar drives the locking block 6 to rotate, so that the locking block 6 is engaged in the groove of the mounting block 5, thereby facilitating the quick connection and combination of the front shell 1 and the rear shell 2.

[0030] One end of the rubber plug 3 is connected to an installation ring 12. An insert block 13 is installed on one side of the installation ring 12. One end of the insert block 13 is inserted into a limit block 14 through a groove. A second rotating block 15 is installed on one side of the limit block 14. A wedge block 16 is provided on the top of the second rotating block 15. A pressure rod 17 penetrating the front shell 1 is provided on one side of the wedge block 16. A telescopic spring 18 is connected between the second rotating block 15 and the groove of the front shell 1 through a movable block. A return spring 19 is installed inside the front shell 1 through a groove. A telescopic block 20 is provided on one side of the return spring 19. The telescopic block 20 is located on one side of the insert block 13 through the return spring 19. The second rotating block 15 is connected to the groove of the front shell 1 through a rotating shaft.

[0031] In practical implementation, when adding toner to the toner hopper of the front shell 1, the two sets of pressure rods 17 are simply pressed into the groove of the front shell 1. Since the ends of the pressure rods 17 and the wedge blocks 16 that are close to each other are both inclined structures, the pressure rods 17 will press the wedge blocks 16 when they are pressed. The wedge blocks 16 will rotate when they are pressed, and the second rotating block 15 will rotate, causing the second rotating block 15 to move the limiting block 14 out of the groove of the insert block 13. Without the limiting block 14 limiting the insert block 13, the reset spring 19 will reset and push the insert block 13 on one side of the front shell 1 to the outside through the telescopic block 20. Thus, the rubber plug 3 can be ejected from one side of the front shell 1 through the mounting ring 12. At this time, it is convenient to add toner to the toner hopper.

[0032] After the toner is added, the rubber plug 3 is pushed into the toner compartment of the front shell 1 by the mounting ring 12, and the insert block 13 on one side of the mounting ring 12 presses against the telescopic block 20. At the same time, the insert block 13 presses against the inclined surface of the limiting block 14, causing the limiting block 14 to rotate upward through the second rotating block 15, and press against the movable block and the telescopic spring 18 at one end of the second rotating block 15. When the insert block 13 is fully installed in the groove of the front shell 1, the telescopic spring 18 will return to its original position and drive the second rotating block 15 to rotate in the opposite direction, so that the limiting block 14 at one end of the second rotating block 15 is inserted into one end of the insert block 13. Thus, the mounting ring 12 and the rubber plug 3 can be fixed on the outside of the toner compartment at one end of the front shell 1, and the rubber plug 3 can increase the sealing effect of the toner compartment.

[0033] See Figure 1 , Figure 5 , Figure 6 and Figure 7 It is known that during use, simply push the pressure rod 17 so that the pressure rod 17 squeezes the second rotating block 15 through the wedge block 16 and drives the limiting block 14 to move out of the groove of the insert block 13. Then the telescopic block 20 will be reset by the reset spring 19 and eject the movable ring and the insert block 13 from one side of the powder compartment of the front shell 1, thus making it convenient for the user to add toner.

[0034] In summary: When using this modular toner cartridge case, the toner cartridge body 4 can be placed between the front shell 1 and the rear shell 2. Then, the front shell 1 and the rear shell 2 can be connected and fixed by the mounting block 5 and the locking block 6. The front shell 1 and the rear shell 2 can protect the toner cartridge body 4 in the middle. The rubber plug 3 at one end of the front shell 1 can be opened, and toner can be injected into the toner hopper of the front shell 1. The rubber plug 3 can then be fixed by the insert block 13 and the limiting block 14. Then, the entire toner cartridge case can be installed on the printer through the front shell 1 and the rear shell 2, thus ensuring that the printer can be used normally. This is the characteristic of the use of this modular toner cartridge case. The contents not described in detail in this instruction are existing technologies known to those skilled in the art.
