As shown in fig. 2, the present embodiment provides an interlocking double door, which comprises two closing doors and two control boxes 1, wherein the two closing doors are respectively disposed at two sides of an isolation buffer room, one closing door is communicated with the isolation buffer room and a ward, and the other closing door is communicated with the isolation buffer room and a medical office. The other closing door corresponding to any closing door is a pair door; the two closed doors are a main door and a pair door respectively, wherein any one closed door is the main door, and the other closed door is the pair door.
Two control boxes 1 correspondingly control a closed door, and every control box 1 controls a closed door, and two control boxes 1 are connected with each other. Preferably, each control box 1 is mounted on a bulkhead adjacent to the closing door.
When one of the closed doors is opened, the control box 1 corresponding to the closed door sends an opening signal to the control box 1 of the opposite door, and the opposite door control box 1 controls the opposite door to be locked and cannot be opened; when one of the closed doors is closed, the control box 1 corresponding to the closed door sends a closing signal to the control box 1 of the opposite door, the opposite door is unlocked from the control box 1 of the opposite door, and the opposite door can be opened. Specifically, when the local door is opened, the local door sends an opening signal to the control box 1 of the local door, and the control box 1 of the local door continues to send the opening signal to the control box 1 of the opposite door.
Further, in one embodiment, as shown in fig. 4 and 5, the closing door is provided with a rotating handle 36 for opening or closing the closing door, and the interlocking double doors include locking devices 5 for restricting the rotation of the rotating handle 36, each locking device 5 being matched with one closing door; the two control boxes 1 are respectively connected with two locking devices 5.
When the control box 1 receives a door opening signal, the locking device 5 for controlling the door locks the rotating handle 36 of the door, so that the rotating handle 36 cannot rotate. When the control box 1 receives a closing signal of the door, the locking device 5 controlling the door releases the restriction of the rotation handle 36 of the door, so that the rotation handle 36 can rotate to open the door.
Further, as shown in fig. 3, on the basis of the first embodiment, the control box 1 includes a door-to-door state display device 14 and a local door opening button 15, and when the control box 1 receives an opening signal or a closing signal for the door, the door-to-door state display device 14 displays to visually see whether the door is in an opened state or a closed state.
When the door state display device 14 displays that the door is closed, the door opening button 15 is activated, and the locking device 5 is controlled to release the restriction of the rotation knob 36 by pressing the door opening button 15.
When the door state display device 14 displays that the door is opened, the door opening button 15 is disabled, the door opening button 15 is not pressed to be disabled, and the locking device 5 cannot be controlled to release the limitation on the rotating handle 36 through the door opening button 15.
