Description

Carbon powder box reset gear

Technical Field

The utility model relates to a cartridge field especially relates to a cartridge gear that resets.

Background

Most toner cartridges in the market are provided with a zero clearing reset counting gear, and after the toner cartridges are firstly loaded into a printer, the gear can rotate to touch a counter part of the printer to complete zero clearing counting, and then the toner cartridges are stopped at a specific position and do not rotate any more. After the test is completed and the user is added and divided again, the powder box must be disassembled in the production factory, and the gear is manually installed or rotated to the initial position, otherwise, the printer cannot detect the carbon powder box and cannot continue working. Among the prior art, the cartridge that has reset function often need carry out the institutional transformation on box body end cover or box body itself, no matter add the plectrum, depression bar or prismatic and so on structure, all need carry out the design of drawing the mould again to the cartridge, greatly increased the processing cost and the use cost of product, and after long-time the use, above-mentioned structure leads to spacingly because of reasons such as wearing and tearing, the precision that resets descends, influence life, need change just can keep the effect that resets to whole cartridge, the use cost of product has further been improved.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome prior art not enough, provide a simple structure, convenient change to effectively improve product life and reduce use cost's a cartridge reset gear.

The utility model adopts the technical proposal that: the utility model discloses a gear body, respectively set up in gear body upper surface and lower surface and with coaxial traveller and the connecting hole of gear body be provided with no tooth section breach on the gear body, be provided with the cambered surface that resets in the no tooth section breach, the cambered surface that resets is from up encircleing down gear body axle center design the traveller top still is provided with rather than sliding fit's key that pushes down, push down be provided with on the key with the position with the guide post of cambered surface looks adaptation that resets, push down the key with still be provided with the spring between the gear body upper surface.

Preferably, the bottom of the press key is provided with a sleeve in sliding fit with the sliding column, the spring is arranged in the sleeve, the top of the spring abuts against the bottom of the press key, and the bottom of the spring abuts against the top of the sliding column.

Preferably, a sector shifting piece for triggering a printer sensor is further arranged at the bottom of the gear body.

Preferably, the bottom of the guide post is designed to be an arc surface, and the arc surface is matched with the reset arc surface.

Preferably, a clamping strip matched with the printer end cover is further arranged on the outer side wall of the press key.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model realizes the rotary reset of the gear body through the matching between the guide post and the reset cambered surface, and achieves the aim of zero clearing of the printer counting; after the toner cartridge is taken out of the printer by an operator, the pressing key is pressed downwards, the guide post slides from the reset arc surface in the pressing process and drives the gear body to rotate, the whole reset process is completed by the gear, and the whole reset process is not matched with the toner cartridge body or the toner cartridge end cover, so that the structure of the toner cartridge is not required to be modified, and the processing difficulty and the production cost of the toner cartridge are effectively reduced; meanwhile, the guide post is connected with the reset arc surface through the arc surface, so that the contact precision is not reduced due to the fact that abrasion is not easy to occur after the guide post is used for a long time, and the service life of a product is guaranteed; the utility model discloses in the middle of concentrating on gear itself with the reset function, receive to damage at the gear and lead to the not good back of reset function, only need change alone the gear can, further reduced use cost. Therefore, the utility model discloses simple structure, convenient change to effectively improve product life and reduce use cost.

Detailed Description

As shown in fig. 1 and 2, the utility model discloses a gear body 1, set up respectively in 1 upper surface of gear body and lower surface and with 1 coaxial traveller 2 and the connecting hole of gear body be provided with toothless section breach 3 on the gear body 1, be provided with the cambered surface 4 that resets in the toothless section breach 3, the cambered surface 4 that resets is followed up encircleing from the design of 1 axle center of gear body 2 top of traveller still is provided with rather than sliding fit's push down key 5, be provided with on the push down key 5 with the position with the guide post 6 of 4 looks adaptations of cambered surface that resets, push down key 5 with still be provided with spring 7 between 1 upper surface of gear body. The utility model discloses it is different with the mode that utilizes count gear and cartridge end cover structure to mutually support among the prior art, utilizes press down key 5 and push down the in-process, drive guide post 6 down move and slide on the cambered surface 4 that resets, thereby make gear body 1 is toward turning round and is moved to the zero clearing reset position in, realizes the effect that resets, later press down key 5 and resume initial position under spring 7's the effect. Through the utility model discloses, the producer need not to add the structure that special help count gear resets on cartridge or toner cartridge end cover, greatly reduced the production finished product of producer, use simultaneously for a long time lead to the product wearing and tearing back, only need alone to reset the gear change can, need not to change whole cartridge, reduced the use cost of product. The reset arc surface 4 is designed around the axis of the gear body 1 and is integrally injection-molded with the gear body 1.

In this embodiment, the bottom of the push-down key 5 is provided with a sleeve 8 in sliding fit with the slide column 2, the spring 7 is arranged in the sleeve 8, the top of the spring abuts against the bottom of the push-down key 5, the bottom of the spring abuts against the top of the slide column 2, and the spring 7 enables the push-down key 5 to smoothly return to the initial position. Gear body 1 bottom still is provided with fan-shaped plectrum 9 that is used for triggering printer sensor, works as guide post 6 moves down and from top to bottom is in when sliding on the cambered surface 4 that resets, gear body 1 rotates to the position that resets, fan-shaped plectrum 9 triggers printer sensor, accomplishes the count zero clearing. The guide post 6 bottom is the cambered surface design, this cambered surface with 4 looks adaptations of cambered surface that reset through the contact between two cambered surfaces, compare in the contact between traditional edges and corners structure, more can avoid damaging, effectively prolongs the life of product. Still be provided with on the 5 lateral walls of push down key with printer end cover matched with screens strip 10, screens strip 10 is used for push down key 5's location avoids push down key 5 because of spring 7's resilience effort fly out cartridge.

Finally, it should be emphasized that the above-described embodiments are merely preferred examples of the present invention, and are not intended to limit the invention, as those skilled in the art will appreciate that various changes and modifications may be made, and any and all modifications, equivalents, and improvements made, while remaining within the spirit and principles of the present invention, are intended to be included within the scope of the present invention.
