Embodiment 1

[0028] Such as Figure 6 As shown, a sliding cover 210 is provided at the powder outlet on the casing 201 of the powder box 200 .

[0029] Such as Figure 7 As shown, the sliding cover 210 has a cover plate 211 , a bottom plate 212 , a side plate 213 , a rear plate 214 and a tail portion 215 . The tail portion 215 has a first plate 216 , a second plate 217 a , a third plate 217 b and a fourth plate 217 c parallel to each other and perpendicular to the first plate. A rib 218 is formed on both sides of the second plate 217a, a rib 218 is formed on the inner side of the third plate 217b, and a rib 218 is formed on the inner side of the fourth plate 217c. Apparently, the rib 218 as the second limiting part is provided on the tail part 215 .

[0030] Such as Figure 8 As shown, the powder outlet 220 is surrounded by a flange 221 and a sponge pad 224. One side of the sponge pad 224 is bonded to the flange 221, and the other side is in contact with the cover plate 211 of the slid...

Embodiment 2

[0035] The difference between this embodiment and Embodiment 1 is that three pillars perpendicular to the first plate are formed on the first plate at the tail of the slide cover, and the pillars are not only used as the second limiting part, but also as a guide and as a The rib 231 and the rib 232 of the second guide rail cooperate to guide the slide cover to slide.

[0036] In the above embodiments, the first limiting part is not limited to the rib integrally formed with the first guide rail, and may also be a protrusion formed separately, bonded or assembled on the housing.

[0037] In the above embodiments, the first guide rail is not limited to the rib formed on the housing, but may also be a groove formed on the housing, and the tail part is a rib or column that is slidably fitted therewith.

Abstract

The invention relates to a powder box. The powder box comprises a shell, a powder outlet, a slide cover, a second guide rail and a tail part, wherein the powder outlet is formed in the shell and each of the two sides of the powder outlet is provided with a first guide rail distributed along the mounting direction of the powder box; the slide cover is used for sealing the powder outlet and can slide along the first guide rails; the second guide rail is arranged on the shell along the mounting direction, is located on the upstream of the powder outlet and is located between the two first guide rails; the tail part is arranged on the slide cover and is matched with the second guide rail. According to the scheme, the slide cover can be effectively prevented from falling off and is prevented from being clamped by the slide cover.

Description

technical field [0001] The invention relates to a powder box, in particular to a powder box whose powder outlet is sealed by a sliding cover. Background technique [0002] A toner cartridge is a detachably installed component in the printer that supplies toner to the printer. [0003] Such as figure 1 As shown, a conventional powder box 100 is provided with a sliding cover 110 at the powder outlet on its casing 101 . [0004] Such as figure 2 As shown, there is a flange 121 around the powder outlet 120 and a sponge pad 124 on the flange 121. One side of the sponge pad 124 is bonded to the flange 121, and the other side is in contact with the sliding cover 110. The side of the flange 121 The flanks serve as rails 122 . The guide rail 122 is provided with buckles 123 , and the sliding cover is provided with cantilevered buckles 111 . [0005] Such as image 3 As shown, when the sliding cover 110 closes the powder outlet 120 , that is, when the powder outlet 120 is close...
