Embodiment

In order more to understand characteristics of the present utility model place, act is described as follows with next preferred embodiment and conjunction with figs..

See also Fig. 1 to Fig. 4, the opening and closing device 10 that the utility model one preferred embodiment is provided is located on the powder box 12, this powder box 12 has a housing 14 and a meal outlet 16 is positioned at this housing 14 bottom sides, and 10 of this opening and closing devices include a pedestal 20 and a saddle 30.

This pedestal 20 is located at the bottom side of this housing 14, definition one accommodation space 21, an inlet 22 and one outlet 23 between this pedestal 20 and this housing 14, it is corresponding with this meal outlet 16 that these pedestal 20 bottom sides have a breach 24 its positions, the edge of this breach 24 is provided with two locating slots 241, these pedestal 20 sides then tool one guide groove 25 extend along a vertical X of this pedestal 20, also there is a retaining wall 26 in these guide groove 25 outsides, wherein, this guide groove 25 has a high-order section 251, one low level section 253, and a tilting section 252 connects this high position section 251 and this low level section 253; Relatively, this retaining wall 26 also has high-order section 261, one a low level section 263 and a tilting section 262.

This saddle 30 is located in this accommodation space 21 and can be in a primary importance A (as Fig. 3, shown in Figure 6) and a second place B (as shown in Figure 9) between move, this saddle 30 has a rectangular body 31 can be by these 22 these accommodation spaces 21 of insertion that enter the mouth, one opening 32 is positioned at this body 31 central authorities, one projection 33 is extended by these body 31 tail ends and is convexedly stretched in outside this pedestal 20 by this outlet 23, one cantilever 34 is extended by these body 31 head ends, one colludes pawl 35 is located at this cantilever 34 ends, one guide pillar 36 is extended by this cantilever 34 and stretches in the guide groove 25 of this pedestal 20, one protuberance 37 is located at this body 31 and is positioned at the breach 24 of this pedestal 20, and two locating pieces 38 are located at these protuberance 37 2 sides and are placed in the locating slot 241 of this pedestal 20; Wherein, this guide pillar 36 has a re-entrant angle 361 and pastes the retaining wall 26 that is butted on this pedestal 20, thus, when this saddle 30 when this pedestal 20 moves, this guide pillar 36 moves along this guide groove 25, this cantilever 34 can be swung up and down by this guide groove 25 positively with these retaining wall 26 guidings, changes the position that this colludes pawl 35 simultaneously, can avoid the generation of misoperation.

As shown in Figure 3, when powder box 12 still unassembled when an electronic imaging apparatus (figure do not show), this saddle 30 is positioned at primary importance A, and this meal outlet 16 is subjected to the sealing of these saddle 30 bodies 31, makes unlikely the leaking outside of carbon dust ccontaining in these powder box 12 housings 14 (figure does not show); When this powder box 12 is assembled in this electronic imaging apparatus, then extremely shown in Figure 9 as Fig. 5, this opening and closing device 10 will engage with adversary's part 40 of this electronic imaging apparatus and make this meal outlet 16 open, wherein this adversary's part 40 has a stop section 41, a location division 42 and and is pollinated mouthfuls 43, below assembling process decomposed is described as follows:

As shown in Figure 6, when powder box 12 was inserted an electronic imaging apparatus, powder box 12 was that this adversary's part 40 is toward moving right relatively, and this moment, this saddle 30 was positioned at primary importance A, the guide pillar 36 of this saddle 30 is positioned at the low level section 253 of these pedestal 20 guide grooves 25, and this colludes 35 of pawls and is positioned at a releasing position E.

As shown in Figure 7, this powder box 12 continues to move right, and pastes the stop section 41 that is butted on this adversary's part 40 until the projection 33 of this saddle 30, and this moment, this saddle 30 still was positioned at primary importance A, and this colludes pawl 35 and still is positioned at this releasing position E.

As shown in Figure 8, when this powder box 12 continues to move right together with this pedestal 20, this saddle 30 is replaced by this adversary's part 40 and is rested on the original place, the guide pillar 36 of this saddle 30 arrives high-order section 251 by the tilting section 252 of these pedestal 20 guide grooves 25 at this moment, makes the cantilever 34 past beats clockwise of this saddle 30 and make this collude pawl 35 to move down.

As shown in Figure 9, when this powder box 12 moves right the arrival location, this pedestal 20 pastes the stop section 41 that is butted on this adversary's

part

40,33 of the projections of this saddle 30 are disappeared fully in this pedestal 20, this moment, this saddle 30 was positioned at second place B, opening 32 and this meal outlet 16 of this saddle 30, the breach 24 of this pedestal 20 is communicated with, make carbon dust in this housing 14 mouthfuls 43 inject electronic imaging apparatus by being pollinated of this adversary's part 40, the guide pillar 36 of this saddle 30 is positioned at the high-order section 251 of these pedestal 20 guide grooves 25, still the keep down state of beat of the cantilever 34 of this saddle 30, this colluded pawl 35 and was positioned at a latched position F this moment, and shown in Figure 9 is that powder box 12 inserts electronic imaging apparatus fully and finishes the state of assembling.

With this powder box 12 then as shown in figure 10 by the process of taking out in the electronic imaging apparatus, the user holds this powder box 12 to the assistant pulling, the pawl 35 that colludes of this saddle 30 is ended by the card of these adversary's part 40 location divisions 42, make these saddle 30 relative these pedestals 20 move right, when this saddle 30 moves to one the 3rd position C of contiguous this primary importance A by this second place B, the guide pillar 36 of this saddle 30 just is positioned at the tilting section 252 of these pedestal 20 guide grooves 25, and these cantilever 34 distortion this moment make this collude pawl 35 and shift to releasing position E by this latched position F.

As shown in figure 11, this powder box 12 continues to be moved to the left, when the guide pillar 36 of this saddle 30 arrives low level sections 253 via the tilting section 252 of these pedestal 20 guide grooves 25, these 34 beginnings of cantilever make progress the beat homing and not ended by the card of these adversary's part 40 location divisions 42, this colludes pawl 35 and returns back to releasing position E at this moment, this saddle 30 also returns back to primary importance A and this meal outlet 16 is sealed, and two locating pieces 38 of this saddle 30 are filled in respectively in two locating slots 241 of being located at this pedestal 20, make that this saddle 30 is unlikely to be moved relative to this pedestal 20 again.

In said process, this saddle 30 stretches in the guide groove 25 of this pedestal 20 divided by this guide pillar 36, and this guide pillar 36 also pastes the retaining wall 26 that is butted on this pedestal 20 with its re-entrant angle 361, therefore, can avoid cantilever in the known configurations that the disappearance of misoperation easily takes place, and cantilever is difficult for because of above the elastic limit permanent strain; Moreover this pedestal 20 is simple than known configurations with the shape of this saddle 30, and the mould design is comparatively simple, can effectively reduce manufacturing cost.

Based on spirit of the present utility model, the structure of this opening and closing device 10 can be changed design, for example: this meal outlet 16 may not be positioned at this powder box 12 housings 14 bottom sides, this pedestal 20 all can change according to need with the shape of this saddle 30, locating piece 38 numbers of this saddle 30 can be kept to one, or increase to more than three, and locating slot 241 numbers of this pedestal 20 also together, all structural changes that these are easy to imagine, the claim scope that all should be the utility model application contains.
