Preferably, the accommodating hole includes vertical portion and axial part, and the vertical portion is inside fixed seat along perpendicular to solid
The direction on reservation surface extends to fixed seating face, and the axial part is axially extending along photosensitive drums and is connected to vertical portion bottom end；
The elastic string is fixed on the axial part inner wall.
Preferably, the both ends of the locking bar are set as cusp-shaped.
Preferably, the elastic string is nylon rope.
In the utility model, protective cover is equipped with perforative through-hole, and connector is detachable to be snapped onto in through-hole, will be connected
Fitting is connected with protective cover, and the pulling force that elastic string provides can lock protective cover, makes protective cover that lid be kept to overlay in photosensitive drums, if you need to
Remove protective cover, it is necessary to connector be detached with protective cover, opened so as to prevent protective cover from opening by mistake, make photosensitive drums not by the external world
The pollution of dust.
Description of the drawings
Fig. 1 is a kind of sectional view of the toner cartridge for locking protective cover of embodiment of the utility model；
Fig. 2 is a kind of sectional view of the fixed seat of embodiment of the utility model.
Specific implementation mode
The utility model is described in further detail below by specific implementation mode combination attached drawing.
The utility model embodiment provides a kind of toner cartridge for locking protective cover, including toner cartridge ontology, the toner cartridge ontology
Interior to be equipped with photosensitive drums 1, the side of the photosensitive drums 1 is equipped with powder cabin 2, and the other side of the photosensitive drums 1 is equipped with waste powder hopper 3.Powder cabin 2
For tool there are one meal outlet, the setting of meal outlet position, will be in powder cabin 2 there are one the developer roll 21 docked with photosensitive drums 1
Carbon dust is transferred in photosensitive drums 1.Powder-wiping plate is equipped in waste powder hopper 3, it will be in the useless powder hanging fascia to waste powder hopper 3 in photosensitive drums 1.Sense
A part for light drum 1 exposes to except toner cartridge ontology, forms a guide plate 22 extended to photosensitive drums 1 in the bottom of powder cabin 2, leads
Plate 22 guides paper to be contacted with photosensitive drums 1.
The protective cover 4 that can be rotated relative to waste powder hopper 3 is equipped in the outside of the waste powder hopper 3, the protective cover 4 can be located at
In photosensitive drums 1.The concrete structure of protective cover 4 and the related knot that existing protective cover may be used to the connection structure of toner cartridge
Structure, this will not be repeated here.Fixed seat 5 is equipped on the lateral wall of the powder cabin 2, fixed seat 5 can be with powder cabin 2 lateral wall one
Change and be connected, or is additionally fixed on the lateral wall of powder cabin 2.It is equipped with accommodating hole in the fixed seat 5, consolidates in the accommodating hole
Fixed flexible rope 6, elastic string 6 projects over except accommodating hole, and the elastic string 6 is fixedly arranged at the front end with connector 61.The guarantor
