Abstract
The invention relates to a gear protection mechanism for office facilities. The gear protection mechanism comprises a motor, a photographic fixing first-stage gear, a photographic fixing second-stage internal gear, and a photographic fixing second-stage external gear, and is characterized by also comprising a photographic fixing safety pin, a ratchet wheel, and a photographic fixing safety spring. The ratchet wheel is fixed in the center of the photographic fixing second-stage external gear. The photographic fixing safety pin and the photographic fixing safety spring are coaxially installed on a side wall of the photographic fixing second-stage internal gear and through the photographic fixing safety spring the photographic fixing safety pin is pressed on the ratchet wheel, the single transmission movement is realized, and the photographic fixing second-stage external gear is meshed with the photographic fixing first-stage gear. The gear protection mechanism for the office facilities has the advantages of being simple in structure, convenient to install and capable of well protecting a gear transmission system and being widely applied to printers, duplicators and fax machines.
Description
Technical field
The present invention relates to a kind of office equipment accessory, particularly a kind of office equipment gear protection mechanism.
Background technology
Printer all can run into the phenomenon of paperboard in the normal process of printing, most cases paper all can be stuck in fixation unit, now wanting to recover normal printing must take out the paper being blocked, and for the user of printer, taking out is exactly directly paper to be released by the direct method of paperboard, but, on current printer, want directly from fixation unit, paper released and be not easy, because drive motor is directly passed to fixation unit by power by gear train, motor stall when photographic fixing paperboard, now want paper to release, drive the rotation of whole power train with regard to meaning by the strength of paper extraction, comprising motor, this is to be difficult to realize, can only be machine apart, warm-up mill in fixation unit and photographic fixing rubber roll are separated, could will be taken out by paperboard, if machine apart is not directly carried out to paper extraction, very likely damage the gear of power train, cause printer to damage.
Summary of the invention
In view of the problem of above existence, a kind of office equipment gear protection mechanism is provided, carry out paper extraction after fixation unit paperboard time, can be drawn out of smoothly by paperboard and not damage Transmission gears, thus the troublesome operation that can avoid taking apart machine.Concrete technical scheme is; a kind of office equipment gear protection mechanism; comprise motor, photographic fixing one-level gear, secondary annular wheel, photographic fixing secondary outer rotor; it is characterized in that: also comprise photographic fixing safety pin, ratchet, photographic fixing safety spring; ratchet state fixes on photographic fixing secondary outer rotor center; photographic fixing safety pin and photographic fixing safety spring are coaxially arranged on photographic fixing secondary annular wheel sidewall and by photographic fixing safety spring photographic fixing safety pin are pressed on hook tooth; realize individual event and transmit motion, photographic fixing secondary outer rotor engages with photographic fixing one-level gear.
Technique effect of the present invention is simple in structure, easy for installation, has protected well pinion unit, can be widely used in printer, duplicating machine and facsimile recorder.

Embodiment
As Fig. 1, 2, 3, 4, 5, shown in 6, ratchet 4 states fix on photographic fixing secondary outer rotor 3 centers, photographic fixing safety pin 1 and photographic fixing safety spring (9) are coaxially arranged on photographic fixing secondary annular wheel 2 sidewalls and by photographic fixing safety spring 9 photographic fixing safety pin 1 are pressed on ratchet (4) tooth, form a kind of special ratchet device, wherein photographic fixing safety pin 1 can be regarded ratchet as, thereby can realize individual event and transmit motion, be that photographic fixing secondary outer rotor 3 is rotated counterclockwise, the hook tooth 4 at its center drives photographic fixing secondary annular wheel 2 to be rotated counterclockwise by photographic fixing safety pin 1, conversely, in the time that photographic fixing secondary annular wheel 2 is rotated counterclockwise, due to the anti-phase not location of photographic fixing safety pin 1, photographic fixing safety pin 1 will be thrown off with hook tooth 4, photographic fixing secondary annular wheel 2 can not drive hook tooth 4 to be rotated counterclockwise by photographic fixing safety pin 1, photographic fixing secondary outer rotor 3 also just can not be rotated counterclockwise, thereby can not carry-over moment, wherein the effect of photographic fixing safety spring 9 is to make photographic fixing safety pin 1 energy return at once after disengagement.
When principle of work is normal operating conditions, motor 6 passes to photographic fixing secondary outer rotor 3 by photographic fixing one-level gear 7 power, the ratchet device that photographic fixing secondary outer rotor 3 consists of hook tooth 4 and the photographic fixing safety pin 1 at its center passes to photographic fixing secondary annular wheel 2 power, photographic fixing secondary annular wheel 2 passes to fixing heating roller 10 by fixing heating roller gear 5 power again, in the time of fixation unit paperboard, the unexpected stall of motor, paper 8 is stuck between fixing heating roller 10 and photographic fixing rubber roll, now, all there is very large moment in whole power train, when paper 8 is outwards extracted out, pass to 2 one applied moments of photographic fixing secondary annular wheel by fixing heating roller 10 and fixing heating roller gear 5, due to the existence of this special ratchet device, photographic fixing safety pin 1 will be thrown off with hook tooth 4, moment can not be continued to pass to photographic fixing secondary outer rotor 3 again, other parts of power train just can not hinder by paperboard 8 and release from fixation unit, thereby protect whole pinion unit.
