Description
Technical field
The utility model relates to a kind of cartridge, particularly a kind of toner cartridge of laser printer counts tooth mounting structure.
Background technology
Machine is recognized by counting tooth counting after powder box installation.Counting tooth counting is recognized machine process and is: after new powder box loads printer, printer driver gear rotates, and rotated by the gear set drive counting tooth on powder box, when counting tooth rotates, the top pin on its top can dial the counter switch of printer.Only less than half-turn profile of tooth on counting tooth, blocked by the position-limit foot that it is arranged after counting tooth rotates half-turn, thus be parked in a fixing stuck position, now, the counter switch of top, counting tooth top pin jack-up printer, recognizes machine and completes, machinery panel green light, ready.When printer powder box exhausts serviceable life, machinery panel amber light is bright, and the prompting powder box life-span is most, and can not continue to print, now powder box must take out from printer, adds carbon dust, and makes counting tooth reset to initial position again.
But the counting tooth under prior art, as shown in Figure 1, Figure 2, Figure 3 shows, counting tooth 100 is arranged on stationary shaft 200 set by one end, powder storehouse 300 and rotates, gear on counting tooth 100 can engage with gear set on one side, counting tooth 100 bottom is provided with spacing card base 110, spacing card base 110 is positioned at counting tooth 100 excircle lower position, for limiting the torsion spring 400 counting tooth 100 initial position between counting tooth 100 and powder storehouse 300.At the initial position of counting tooth 100, torsion spring 400 one end clipping is set by powder storehouse 300 between two locating pieces 310, torsion spring other end top is pressed on spacing card base 110, under the effect of torsion spring 400 tension force, counting tooth 100 is along the circumferential direction subject to rotating forward precompression, now, counting tooth 100 is compressed between torsion spring and gear set and can not gets loose, and prepares for next step counting tooth 100 rotates.
Gear set drive counting tooth 100 turn to fasten stuck position time, spacing card base 110 on counting tooth 100 rotates with counting tooth 100, spacing card base 110 on counting tooth 100 will inevitably rest in traditional gear system 500 side, namely counting tooth 100 turns to and fastens stuck position, completes and once counts.When needing to reuse, can not continue to rotate forward because spacing card base 110 limits counting tooth 100, staff installs after can only taking out counting tooth 100 again, and counting tooth 100 could be installed back initial position, powder box could successfully use.Powder box process all must according to this job step each time, and the staff that this process of dismounting cartridge generally also only knows cartridge just can operate, extremely not convenient, obviously increases many troubles to related work.
Utility model content
The utility model object be to provide a kind of structure simple, counting tooth just can be made to reset to initial position without the need to taking gear end cap apart, a kind of toner cartridge of laser printer facilitating powder box to add powder counts tooth mounting structure.
The technical scheme in the invention for solving the technical problem is:
A kind of toner cartridge of laser printer counts tooth mounting structure, comprise counting tooth and powder storehouse main body, and be arranged on the gear train assembly of powder storehouse body end, counting tooth is arranged on stationary shaft set by main body one end, powder storehouse and rotates, a transmission gear engaged transmission on counting tooth excircle and gear train assembly, powder storehouse main body is also equipped with limit and counts that tooth is initial, the torsion spring of final position; One end is stiff end, torsion spring stiff end is pressed against locating piece side in the main body of powder storehouse, the torsion spring other end is depression bar, described counting tooth bottom is cylindrical shape, spacing block set is provided with, without interference rotation between spacing block set and described gear train assembly, powder storehouse main body in the counting tooth bottom of cylindrical shape; Described depression bar coordinates with the spacing block set two ends of counting tooth bottom and counts tooth circumference freely rotate to limit.
Described spacing block set one end is the initial positive stop end of counting tooth, and counting tooth is when reference position, and described depression bar is pressed on the initial positive stop end of counting tooth and rotates backward to limit counting tooth circumference; The described spacing block set other end stops positive stop end for counting tooth, count tooth rise from reference position turn to termination put time, described depression bar be pressed on counting tooth after right cylinder slides to stop positive stop end and count tooth circumference rotate forward to limit along described counting tooth bottom.
Described spacing block set is also provided with middle transition section, and described depression bar can slide through middle transition section from counting tooth spacing clearing end side and be transitioned into the initial positive stop end side of described counting tooth.
Wherein, middle transition section is set to ramped shaped or has the arc shape of smooth surface.
The utility model has following advantages:
Counting tooth bottom is cylindrical shape, is provided with spacing block set in the counting tooth bottom of cylindrical shape, and spacing block set one end is the initial positive stop end of counting tooth, and counting tooth is when reference position, and depression bar is pressed on the initial positive stop end of counting tooth and rotates backward to limit counting tooth circumference; The spacing block set other end stops positive stop end for counting tooth, count tooth rise from reference position turn to termination put time, depression bar stops positive stop end count tooth circumference and rotate forward along being pressed on counting tooth after described smooth section is slided limit; Spacing block set is also provided with middle transition section, and depression bar can slide through middle transition section from counting tooth spacing clearing end side and be transitioned into the initial positive stop end side of described counting tooth; Known from said structure, depression bar is pressed on the initial positive stop end of counting tooth and rotates backward to limit counting tooth circumference, count tooth rise from reference position turn to termination put time, depression bar stops positive stop end count tooth circumference and rotate forward along being pressed on counting tooth after smooth section is slided limit; But spacing block set is also provided with middle transition section, under external force, can it be made to continue to rotate forward initial position by hand rotation counting tooth, namely counting tooth of the present utility model can hand-reset, structure is simple, realize counting tooth just can being made to reset to initial position without the need to taking gear end cap apart, a kind of toner cartridge of laser printer facilitating powder box to add powder counts tooth mounting structure.
