[0033] 1. Electric closing:
[0034] When the door is in the open state, the cylinder 4 takes in air, and the cylinder push rod 401 pushes the lock 5 to rotate, thereby pushing the motor gear 2 to the sector gear 1 to mesh the two gears. By adjusting the adjusting screw 402 on the cylinder push rod 401, the gear meshing gap can be adjusted so that the gears can mesh well;
[0035] The driving motor 3 rotates forward, driving the motor gear 2 to drive the sector gear 1 to rotate;
[0036] The sector gear 1 drives the door shaft 11 connected with the spline shaft 10 to rotate to realize electric door closing;
[0037] The stop pin 101 on the sector gear 1 pushes the trigger plate 7 to trigger the switch assembly, the switch assembly outputs a signal to the door controller, and the door controller completes the door closing action.
[0038] 2. Electric door opening:
[0039] When the door is in the closed state, the cylinder 4 takes in air, and the cylinder push rod 401 pushes the lock gear 5 to rotate, thereby pushing the motor gear 2 to the sector gear 1 to mesh the two gears. By adjusting the adjusting screw 402 on the cylinder push rod 401, the gear meshing gap can be adjusted so that the gears can mesh well;
[0040] The drive motor 3 is reversed to drive the motor gear 2 to drive the sector gear 1 to rotate;
[0041] The sector gear 1 drives the door shaft 11 connected to it through the spline shaft 10 to rotate to realize electric door opening.
[0042] 3. Manual closing:
[0043] When the door is in the open state, the cylinder 4 is exhausted, the lock 5 is reset under the action of the lock 5 reset torsion spring 701 and the cylinder push rod 401 is retracted, and the motor gear 2 is separated from the sector gear 1;
[0044] Manually close the door in place;
[0045] The cylinder 4 takes in air, so that the motor gear 2 meshes with the sector gear 1 to achieve locking.
[0046] 4. Emergency unlock to open the door manually:
[0047] When the door is closed, operate the emergency unlocking device to exhaust the cylinder 4, and the lock 5 is reset under the action of the lock 5 reset torsion spring 701 and the cylinder push rod 401 is retracted, so that the motor gear 2 and the sector gear 1 are separated ;
[0048] Complete the door opening manually.
[0049] 5. Full locking: at any position, cylinder 4 air intake, motor gear 2 meshes with sector gear 1, through the self-locking function of worm gear motor 3, it can be locked at any position.
[0050] In addition, such as Image 6 Shown are the left and right finger guard strips of the present invention.
