Description

Technical Field

[0001] The utility model relates to the technical field of selenium drums, in particular to a selenium drum structure. Background Art

[0002] The toner cartridge is composed of a first powder box and a second powder box. The first powder box and the waste powder box are both provided with connecting ears, and pins are inserted into the two connecting ears so that the first powder box and the second powder box can be connected in a relatively rotatable manner.

[0003] Based on the above, the existing technology has a technical problem: when assembling the first and second powder boxes, workers need to insert the pin into the two connecting ears. This assembly process is not easy due to the small size of the pin, resulting in low assembly efficiency and affecting production efficiency. Further improvement is needed. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems in the prior art. To this end, the utility model provides a toner cartridge structure that is easy to assemble.

[0005] A toner cartridge structure designed for this purpose includes a first powder box and a second powder box, wherein the second powder box is provided with connecting ear seats on the left and right sides, and the connecting ear seats are provided with an axis hole, and the left and right sides of the first powder box are detachably connected with side covers, and the side covers are fixedly provided with a pin shaft, and the pin shaft is movably inserted into the axis hole.

[0006] Preferably, arc-shaped positioning grooves are provided on the left and right lower surfaces of the first powder box, and the connecting ear seats are movably inserted into the arc-shaped positioning grooves.

[0007] Preferably, elastic elements are respectively provided on the left and right sides between the rear lower wall of the first powder box and the rear upper wall of the second powder box;

[0008] The elastic element is used to apply an upward force to the first powder box so that the developing roller and the drum core work in coordination.

[0009] Compared to the prior art, the present invention features detachable side covers on the left and right sides of the first powder box, each of which is fixed with a pin that movably engages within the shaft hole. The present invention incorporates detachable side covers with the pin integrated into them. During assembly, the first and second powder boxes are first aligned, and then the side covers are assembled from the left and right sides. Inserting the pin into the shaft hole allows the first and second powder boxes to be rotationally connected. This eliminates the pin assembly step, optimizing the assembly process and improving efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] See also Figure 1-Figure 4 A toner cartridge structure includes a first powder box 10 and a second powder box 20. The second powder box 20 is provided with connecting ears 210 on the left and right sides, and the connecting ears 210 are provided with shaft holes 220. The first powder box 10 is detachably connected to the left and right sides with side covers 30, and the side covers 30 are fixedly provided with pins 310, and the pins 310 are movably inserted into the shaft holes 220. The utility model provides a detachable side cover, which integrates the pins on the side cover. During assembly, the first and second powder boxes are first aligned, and then the side covers are assembled from the left and right sides. After the pins are inserted into the shaft holes, the first and second powder boxes are rotatably connected. The utility model eliminates the step of assembling the pins, optimizes the assembly process, and improves assembly efficiency.

[0016] See also Figure 4 , arc-shaped positioning grooves 110 are provided on the left and right lower surfaces of the first powder box 10, and the connecting ear seat 210 is movably inserted into the arc-shaped positioning grooves 110. The arc-shaped positioning grooves 110 and the connecting ear seat 210 can be inserted and positioned, facilitating alignment of the two to facilitate insertion of the pin 310 into the pin hole 220. In this embodiment, the connecting ear seat 210 is inserted into the arc-shaped positioning grooves 110, and the connecting ear seat 210 can rotate within the arc-shaped limiting grooves 110 with the pin 310 as the axis, so that the first powder box 10 can rotate relative to the second powder box 20.

[0017] See also Figure 3 Elastic elements 60 are respectively provided on the left and right sides between the rear lower wall of the first powder box 10 and the rear upper wall of the second powder box 20; the elastic elements 60 are used to apply an upward force to the first powder box 10 so that the developing roller 40 and the drum core 50 work together.

[0018] Furthermore, the elastic element 60 is a spring.

[0019] See also Figures 1 to 4 The first powder box 10 is a powder bin, and the second powder box 20 is a waste powder bin.
