Embodiment 1
[0025] according to figure 1 , 2 , 3, 4, 5, 6, 7, and 8, the present embodiment provides a shielded electric fan-shaped door, including a door frame 1 and a door body 2, and the door frame 1 and the door body 2 are all treated with closed galvanizing, which improves The surface metal strength and continuous conductive state, the right side of the door body 2 is hingedly installed on the door frame 1, the left side of the door body 2 is connected to the rotating shaft 3, and the two ends of the rotating shaft 3 extend to the outside of the door body 2 and are respectively connected to the outer The handle 4 and the inner handle 5 are provided with a spur gear 6 on the side of the rotating shaft 3 near the outer handle 4, the right side of the spur gear 6 is engaged with the first spur rack 8 driven by the electric cylinder 7, and the left side of the spur gear 6 is engaged with a The second straight rack 9, the upper and lower ends of the second straight rack 9 are fixed with ...
Embodiment 2
[0034] according to Figure 9 As shown, a shielded electric fan-shaped door also includes a distribution box 41. The power distribution box 41 is used for the overall power supply of the shielded electric fan-shaped door. The two sides of the top of the distribution box 41 are respectively provided with a current input interface and a current output interface. On the electric box 41, a box door is hingedly installed, and the distribution box 41 is connected to 220V alternating current through the current input interface, and the alternating current of 220V is converted into the direct current output value of 24V or 12V to shield the electric sector door.
[0035] When in use, first the 220V alternating current enters the distribution box 41 through two direct current power supplies, and two direct currents of 24V and 12V come out, and then enter the motor control module 30 from the trunking 39 to the drag chain 40, and then from the motor control module 30 The signal line is c...
