Chain weight movement for full-automatic cochain, need the periodically actuating mechanism of auomatic fixing chain of an energy, the mechanism of giving the correct time of mechanism and getting ready only needs a shared actuating mechanism regularly when walking generally speaking, mechanism is inconsistent with the position of the required cochain of weight of getting the mechanism of giving the correct time ready when considering away, can respectively be provided with regularly actuating mechanism so get give the correct time mechanism and chain reversing device ready, regularly actuating mechanism is fixed on the rear plate back side, regularly actuating mechanism has a pair of gear pair 61,62, gear 61 is fixed on the axle head of great wheel axle, on the axle of gear 62, fix a cam 63, gear 62 tops are provided with and the hinged swing span 64 of rear plate, has deep-slotted chip breaker 68 on the rear plate, guide finger 69 is set on the swing span relevant position, guide finger moves in deep-slotted chip breaker, to guarantee the swing span smooth rotation, on swing span, be provided with impact bar 70, impact bar is placed in the impact bar support 72 that is fixed on the swing span, impact bar can move forward and backward in its support, be fixed on stage clip 66 and the thrust spring 67 that contacts with impact bar on the rear plate being provided with above the swing span, on impact bar, be provided with contact with cam 63 prominent sharp 71, the impact bar front end is provided with contact block 65 in limited time, and its front upper place is provided with microswitch K.

Sketch principle of work of the present invention, mechanism's cochain is an example when walking.

A pair of gear pair 61 in the timing actuating mechanism, the 62nd, the gear of control cycle, gear 62 drives cam 63 and rotates, turn to certain position, on cam 63 and the impact bar 70 prominent sharp 71 thrown off, under the effect of thrust spring 67, impact bar moves forward, the 65 contact microswitch K of contact block in limited time on the impact bar, microswitch K does the short unlatching of rising, relay work start-up time, power connection, machine operation drives series of gears and rotates, and in these electromagnet 23 adhesives simultaneously, ambulatory splint 16 is to lower swing in the drive, and make down ambulatory splint 18 to lower swing by web joint 14, gear 13 and last sprocket gear 35 engagements, sprocket gear is done the rotation opposite with walking the great wheel sense of rotation in the drive, walks great wheel because ratchet 32, the effect of ratchet 33, stop operating, the whole cochain time is the time in several seconds only.In this process, the connecting rod 19 of the compensation mechanism that is connected with last ambulatory splint is subjected to the effect of ambulatory splint and spring 21, slowly move downward, compensating lever 24 is slightly upwards lifted, 26 contacts of active ratchet are walked two and are taken turns, and take turns and apply acting force walking two, keep walking two to take turns and be rotated further, whole last chain process, walking two amplitudes of taking turns the needs rotation is about 1/6 tooth.Last sprocket gear 35 is rotated by chain 29 and is driven the weight lifting up to the push rod 56 that touches control enclosure 55, and continue to promote push rod and rise, when the S1 contact block on the push rod touches microswitch K1, motor stops operating, this moment is because the machinery inertial effect, weight promotes push rod to be continued to rise, and contact block S2 touches microswitch K2, cuts off micro electromagnetic and inhales ferroelectric source, because the engagement force between gear is very big, by the pulling force of spring 12, this breaks away from gear can't to make gear 13 and last sprocket gear 35, when the contact block S1 on the push rod touches microswitch K3, motor reverses immediately, engagement force between gear reduces to zero, and under spring 12 effects, gear 13 breaks away from last sprocket gear 35, electrical inversion time only 2～3 seconds, the time relay is cut off the electricity supply, and the whole chain process of going up finishes, and returns to normal.

Regularly actuating mechanism is after finishing impacting start, microswitch K is in closed condition, as the cochain cycle be six days, after then treating 108 hours, touch prominent sharp 71 on the impact bar before cam 63 is heavy, promote impact bar and reset, the swing span swing, guarantee that impact bar contact block in limited time of impact bar when resetting can not contact microswitch K, prevent the actuating mechanism misoperation, stage clip 66 helps swing span to reset.

The present invention can both be provided with regularly starter gear, hand was set by microswitch K again; Direct hand also can only be set becomes the chain weight movement of semi-automatic cochain by microswitch K.

The invention solves chain weight clock auomatic fixing chain problem, and when not influencing, complete machine structure is reliable, and is not fragile in last chain process, uses special formula just.
