Technical Field

[0001] The utility model relates to the technical field of electric-controlled protective closed doors, in particular to an opening and closing device for electric-controlled protective closed doors. Background Art

[0002] Protective sealed doors are mainly used to prevent the leakage of harmful substances such as hazardous substances and toxic gases. They have the function of blocking shock waves and isolating toxic agents. The design and installation of such doors need to consider multiple factors, including door type, size, material, installation location, etc.

[0003] Announcement No. CN214463556U discloses an opening and closing device for an electrically controlled protective closed door. The servo motor drives the two active gears on the rotating rod to rotate and drive the two positioning plug-in tooth plates to move to the left, thereby driving the positioning plug-in tooth plates to move to the left and plug them into the rectangular limit tube of the door frame; when there is a power outage or the servo motor fails, the fixing bolts on the clamping plate are removed from the closed door, and then the clamping plate is opened to lift the positioning seat. At this time, when the driving gear is separated from the positioning plug-in tooth plate, the positioning plug-in tooth plate is reset under the action of the tension spring, thereby being pulled out of the rectangular limit tube of the door frame. The entire structure is simple and easy to operate.

[0004] The opening and closing device of the electrically controlled protective sealed door has a simple structure and is easy to operate. The fixing bolts on the clamping plate are removed.
