Interior rotation, performance is exactly that power transmission shaft 1 rotates clockwise in figure 4, and the first ratchet 4-1 is at the work of torsion spring
With lower to first ratchet 3-1 deflection, under the effect of the first ratchet 4-1 and the first ratchet 3-1, first from
Driving wheel 2-1 also rotates clockwise, and at this moment, performance is exactly that power transmission shaft 1 rotates counterclockwise in figure 5,
Second ratchet 4-2 is to the second ratchet 3-2 deflection under the effect of torsion spring, and the second ratchet 4-2 slips over the second spine
Hook tooth on wheel 3-2, the second driven pulley 2-2 does not rotates.When power transmission shaft 1 rotates to another direction,
Based on same principle, the second driven pulley 2-2 rotates with power transmission shaft 1, and the first driven pulley 2-1 does not rotates.
Thus realize the purpose of symmetrical single-direction transmission.
Seeing accompanying drawing 1, one end of rope 10 is wrapped on the first driven pulley 2-1 clockwise, the other end
After first, second and third angle pulley 9-1,9-2,9-3, wrapped anti-clockwise is at the second driven pulley 2-2
On, the rope between second and third angle pulley 9-2,9-3 is provided with the collar 14, connecting rod 12 is arranged
In the collar 14 and the collar 14 can slide on connecting rod 12.
Seeing accompanying drawing 6,7, the two ends of plastic sheeting 13 free end that leaks informaton are connected with connecting rod 12, and leak informaton plastics
The mid portion of thin film 13 free end is not connected with connecting rod 12 to reserve the space that the collar 14 slides.
When unlatching is leaked informaton mouthful, motor rotation, the second driven pulley 2-2 is wound around rope, the first driven pulley 2-1
Along with rotation, the collar on rope 10 pulls connecting rod to move to first and second angle pulley 9-1,9-2 direction,
The mouth that leaks informaton is opened.When closing is leaked informaton mouthful, motor rotates backward, and the first driven pulley 2-1 is wound around rope, the
Two driven pulley 2-2 are along with rotation, and the collar on rope 10 pulls connecting rod to away from first and second angle pulley
The direction of 9-1,9-2 is moved, and the mouth that leaks informaton is closed.In this process, the collar 14 slides along connecting rod 12.
In order to prevent the collar 14 due to the effect of eccentric force during pulling connecting rod 12, the plastics that leak informaton are thin
Film 13 deflects distortion, and the control device that leaks informaton is additionally provided with guiding mechanism, and described guiding mechanism includes guiding
Slide block 16 and guide post 15, guide runner 16 is arranged on the two ends of connecting rod 12, and guide runner 16 is arranged
