Description

Technical Field

[0001] The utility model relates to the technical field of carbon powder cartridges, in particular to a powder cartridge resetting structure. Background Art

[0002] Toner cartridges are copy consumables products provided for multi-function copiers and laser printers. Printer consumables (compatible consumables) can be roughly divided into three categories: ribbons, inkjet and laser. Toner cartridges are an important component in laser printers, and toner is a solid powdery substance.

[0003] Most toner cartridges are equipped with a counting and resetting assembly. Currently, the toner cartridge resetting assemblies on the market have a complex structure and are very inconvenient to operate. Therefore, some people have come up with the idea of ​​using a reset limit spring to achieve automatic resetting. For example, the Chinese utility model patent with announcement number CN213338330U specifically discloses an automatic resetting side cover structure and a toner cartridge.

[0004] However, when actually using the reset limit spring piece used in the above-mentioned toner cartridge, people will find that the reset limit spring piece is connected to the side cover body through the mounting portion provided at the end. However, this connection result is very unstable, and it is easy to cause the mounting portion to pop out from the side cover seat, affecting its normal use. Therefore, the utility model proposes a powder cartridge reset structure. Utility Model Content

[0005] The purpose of the present invention is to provide a powder box reset structure to solve the problems raised in the above background technology.

The reset spring is squeezed and deformed when the toner cartridge is installed and used. When in use, when the counting gear rotates to the spring limiter at the through hole, they engage with each other, causing the counting gear to stop rotating and complete the machine recognition. The reset spring automatically returns to its original position when the toner cartridge is removed from the printer, separating the spring limiter from the gear limiter. At this time, the counting gear continues to rotate, completing the automatic reset.

For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0024] See also Figure 1-5The utility model provides a technical solution: a powder box reset structure, including a side cover body 1, a counting gear 2 is provided on the inner side of the side cover body 1, a gear limiting portion 201 is provided on the counting gear 2, a through hole 101 is opened on the top of the side cover body 1, a mounting slot 102 is opened at the end of the through hole 101, a reset spring piece 3 is provided above the through hole 101, a spring piece limiting portion 301 that cooperates with the gear limiting portion 201 is provided at one end of the reset spring piece 3, and a spring piece card 302 that cooperates with the mounting slot 102 is provided at the other end of the reset spring piece 3, the spring piece card 302 is clamped in the mounting slot 102, and a positioning socket 303 is opened on the side of the spring piece card 302. The reset spring 3 is squeezed and deformed when the toner cartridge is installed and used. When the counting gear 2 rotates to the spring limit part at the through hole 101, they are stuck with each other, causing the counting gear 2 to stop rotating to complete the machine recognition. The reset spring 3 automatically restores when the toner cartridge is taken out of the printer, and the spring limit part 301 is separated from the gear limit part 201. At this time, the counting gear 2 continues to rotate to complete the automatic reset.

[0025] Furthermore, a groove 103 is formed on the side of the side cover body 1, and a C-shaped frame 4 is provided in the groove 103. A screw rod 401 and a slider 402 are provided inside the C-shaped frame 4. The screw rod 401 passes through the slider 402 and the C-shaped frame 4. The screw rod 401 and the slider 402 are connected by a thread. The end of the screw rod 401 is rotatably connected to the groove 103. The slider 402 is provided with a positioning socket 303. The positioning socket 303 passes through the groove 103 and is inserted into the positioning socket 303 to limit the reset spring 3. By rotating the screw rod 401 and driving the slider 402 to move, the slider 402 can be used to drive the positioning plug 403 to withdraw from the positioning socket 303. After withdrawal, the reset spring 3 can be removed from the mounting slot 102.

[0026] Furthermore, a connecting shaft 104 is fixed to the inner side of the side cover body 1 , and the counting gear 2 is connected to the side cover body 1 via the connecting shaft 104 , thereby achieving the installation of the counting gear 2 .

[0027] Furthermore, the spring clip card 302 is U-shaped, and the reset spring 3, the spring limiting portion 301 and the spring clip card 302 are integrally formed.

[0028] Furthermore, the reset spring piece 3 is made of a stainless steel elastic steel sheet to improve the rebound effect.

[0029] Furthermore, a knob 404 is fixed to the end of the screw rod 401 , and the knob 404 is mainly provided to facilitate the rotation of the screw rod 401 .

[0030] Furthermore, the side of the slider 402 is fitted with the C-shaped frame 4 , and the C-shaped frame 4 is used to limit the slider 402 to prevent the slider 402 from rotating when the screw rod 401 is rotated.

[0031] In summary, when the device is in use, the reset spring 3 is deformed under the pressure of the inner wall of the printer, and the spring limiting portion of the reset spring 3 extends into the side cover body 1 through the through hole 101. The counting gear 2 rotates to the gear limiting portion at the through hole 101 and engages with each other, causing the counting gear 2 to stop rotating and complete the machine recognition; when the toner cartridge is removed from the printer, the reset spring 3 automatically returns to its original state, and the spring limiting portion of the reset spring 3 extending into the side cover body 1 separates from the gear limiting portion. At this time, the counting gear 2 continues to rotate, completing the automatic reset. In addition, the reset spring 3 is restricted by the provided positioning rod, thereby improving its fixing effect and preventing the reset spring 3 from detaching. When the reset spring 3 needs to be removed, it is only necessary to turn the knob 404 clockwise so that the knob 404 drives the screw 401 to rotate, so that the screw 401 drives the slider 402 to move, so that the slider 402 drives the positioning rod to withdraw from the positioning socket 303, and then the spring card 302 can be removed from the mounting slot 102. During installation, it is only necessary to insert the spring card 302 into the installation slot 102 again, and then rotate the screw rod 401 counterclockwise so that the screw rod 401 drives the slider 402 to drive the positioning rod to be reinserted into the positioning hole 303 .
