[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. When the door is at the open position A, point A gives a horizontal door opening and closing signal to the controller during operation, the left electromagnetic coil starts, and the fork is pushed toward the DC drive motor, pushing the power gear to engage with the driven gear, and the driven gear drives the horizontal opening walking wheel to close the door and move to point B. The left electromagnetic coil stops, and the fork is centered under the action of the balance spring. At the same time, point C gives a closing signal to the controller, the right electromagnetic coil starts, and the fork is pushed toward the sprocket, the cross clutch is engaged, and the sprocket rotates. The sprocket drives the chain placed on the front door piece to run to the horizontal closing position D. When the door is closed, the front door piece and the rear door piece are in an overlapping state before running. Point A gives a signal to the controller, and the horizontal opening runs to point B. Then point C gives a signal to the controller, and the front door piece moves horizontally to the closing position at point D. Then comes the door opening operation. Point D gives a signal to the controller, and the front door piece moves horizontally to the door closing position at point C. Point B gives a signal to the controller, and the rear door piece overlaps with the front door piece, and the door moves horizontally to the door opening position at point A. During manual operation, the lever in the head assembly is centered by the balance springs at both ends. When the left and right electromagnetic coils are not started, even if the DC drive motor always outputs power, it will not be transmitted to the horizontal opening running wheel or the translation sprocket. Therefore, when the power is off, the door is automatically in the clutch state. Two manual inching switches for the running stroke are set on the head assembly. In the non-automatic mode, the door can be manually controlled to open horizontally or move horizontally to the required position. When the power is off, because the left and right coils stop working, the shift fork is in the middle due to the balance spring. At this time, the door is not affected by the self-locking force of the motor, and the door can be automatically clutched when the power is off;

[0028] 2. Two sets of stabilizing pulleys are fixed at both ends of one side of the front door sheet through brackets, and two sets of slide rails are laid at both ends of the surface of the rear door sheet. The stabilizing pulleys are inserted into the inside of the slide rails. When the front door sheet and the rear door sheet are overlapped, the front door sheet slides on the slide rails using the stabilizing pulleys, thereby improving the stability of the overlap between the front door sheet and the rear door sheet;

[0029] 3. A limit design is set through a preset plate on one side of the bottom of the rear door piece. When the front door piece and the rear door piece are overlapped, a limit block and a limit spring are set under the rear door piece to prevent the front door piece from moving excessively. When the front door piece moves to a certain position, it contacts the limit block and is restricted by the limit spring and can no longer continue to move backward, so it is limited. The limit block is designed to be detachable for easy replacement. First, the preset plate on one side of the limit block is inserted into the preset positioning groove of the rear door piece, and the positioning block on the preset plate is inserted into the positioning groove, and the card slot on the positioning block is engaged with the buckle in the positioning groove to achieve installation. When disassembling, you only need to pull it out with force to improve portability. BRIEF DESCRIPTION OF THE DRAWINGS
