Detailed Description

The utility model will be further described with reference to the following description and embodiments in conjunction with the accompanying drawings:

as shown in fig. 1 to 4, a toner cartridge structure convenient for adding toner comprises a toner bin 1, a toner adding window 2 communicated with an inner cavity of the toner bin 1 is arranged at one end of the toner bin 1, and a sealing cover 3 for sealing the toner adding window 2 is detachably connected to one end of the toner bin 1. Specifically, set up through powder storehouse one end and add the powder window to sealed lid realizes adding the sealed of powder window, and then when needs add the powder, the user directly dismantles sealed lid and adds the powder operation, and simple structure accords with and uses the needs.

The sealing cover 3 is connected to one end of the powder bin 1 in a buckling mode.

One side of the sealing cover 3 is convexly extended with an elastically deformable clamping jaw 4, and one end of the powder bin 1 is concavely provided with a clamping groove 5 matched with the clamping jaw 4. Specifically, the clamping claw and the clamping groove are used for realizing the clamping connection of the sealing cover and the powder bin.

Powder storehouse 1 includes the storehouse body 6 and connects the safety cover 7 that the cover located on the storehouse body 6, the laminating is formed with recess 8 between 7 one end inner walls of safety cover and the 6 one end outer walls of the storehouse body, but 3 one side evaginations of sealed lid extend has elastic deformation's V type card strip 9, V type card strip 9 supports and holds the joint in

recess

8, 5 width of draw-in groove are greater than 4 width of jack catch. Concretely, realize the buckle through jack catch and V type card strip between sealed lid and the powder storehouse and be connected, when needing to dismantle, the user only needs to press V type card strip so that its deformation breaks away from the recess in powder storehouse after, the jack catch can the relative draw-in groove activity, and then the jack catch breaks away from the butt joint of draw-in groove to the dismantlement of sealed lid, thereby avoid the user's maloperation to dismantle or frequently dismantle the fastener that leads to and damage, satisfy the user demand.

One side of the groove 8, which is far away from the bin body 6, protrudes outwards to form a first limiting block 10, and one side of the V-shaped clamping strip 9 extends to form a second limiting block 11 which is used for the first limiting block 10 to abut against and limit. Specifically, when V type card strip butt joint when in the recess, the butt state about stopper two on the V type card strip is with the stopper one in the recess, and then realizes the upper and lower spacing of the relative recess of V type card strip to the user can only break away from the dismantlement of sealed lid through pressing down deformation V type card strip, realizes preventing slow-witted effect.

A flange 12 extends from one end of the V-shaped clamping strip 9 far away from the sealing cover 3, and a gap is reserved between the flange 12 and one end of the bin body 6.
