[0033] The two ends of the positioning frame 27 are plugged into the side of the connecting block 14 through the plug-in slot 24, and the automatic door panel 29 is rotatably connected to the second limit shaft hole 25 through the third rotating shaft 34, so that the automatic door panel 29 can be rotated and adjusted at the side end of the connecting plate 26. One side end surface of the connecting plate 26 is symmetrically provided with a positioning socket. The two ends of the plug-in frame 32 are aligned with the side end surface of the connecting plate 26 through the positioning socket, so that the connecting device 21 and the auxiliary door frame 22 can maintain the same horizontal plane and form an integral connection. The connecting plate 26 is fixedly connected to the driver 10 through the clamping block 28 at the top, so that when the transmission belt inside the driver 10 rotates, the connecting device 21 can be driven to slide synchronously inside the limiting slide 9. The clean room automatic door frame 2 is slidably connected to the side end of the fixed frame 3 through the limiting slide 9, so that the clean room automatic door frame 2 can slide back and forth inside the side of the fixed frame 3. The side of the positioning frame 27 is evenly fixed with a second return spring, which can provide power for the reset of the positioning frame 27.

[0034] Working principle: When the automatic door is in use, the driver 10 is powered on, so that the driver 10 runs and drives the connecting device 21 to slide synchronously inside the limiting slide 9 through the clamping block 28, thereby realizing automatic control of the sliding of the clean room automatic door frame 2, wherein when the clean room automatic door frame 2 slides and expands on the limiting slide 9, the connecting plate 26 inside the clean room automatic door frame 2 will drive one end of the warning poster 13 to slide synchronously, and when the warning poster 13 slides and expands, it will drive the first rotating shaft 11 to rotate synchronously inside the side end of the fixed frame 3, and when the first rotating shaft 11 rotates, it will drive the first return spring 12 on the outer surface of both ends to deform, and when the warning poster 13 is expanded at the side center of the fixed frame 3, it will The warning information and publicity information on the surface of the warning poster 13 are exposed to the outside, thereby playing a warning and publicity role for pedestrians, and the publicity resources of the automatic door can be utilized. In the event of an emergency, emergency evacuation is required. At the same time, when the driver 10 cannot be started, the clean room automatic door frame 2 needs to be manually adjusted. First, pull the adjustment handle 31 to slide horizontally. At the same time, the adjustment handle 31 will drive the plug-in frame 32 to slide synchronously until one end of the plug-in frame 32 is separated from the positioning socket on the side end face of the connecting plate 26. At the same time, the plug-in frame 32 will squeeze the second tensioning spring 33 to shrink, and then pull the automatic door panel 29 to deflect 90 degrees with the third rotating shaft 34 as the axis, so as to avoid blocking the emergency evacuation of personnel. When the flow of people is large, it is necessary Directly push the fixed frame 3 to rotate 90 degrees, so that the main clean room door frame 1 as a whole drives the clean room automatic door frame 2 to deflect, thereby expanding the scope of emergency evacuation and avoiding collision and injury to personnel during evacuation. When replacing the warning poster 13 inside the fixed frame 3, first control the driver 10 to drive the clean room automatic door frame 2 to retract inside the limiting slide 9, so that the warning poster 13 is caused to rotate the first rotating shaft 11 to rewind the warning poster 13 under the elastic force of the first return spring 12, and then rotate the adjusting block 16 to rewind the connecting rope 17 on the outer surface. At the same time, the connecting rope 17 will drive the two sets of positioning plug plates 15 to slide close to each other, and the positioning plug plates 15 will squeeze the first tensioning member at one end when sliding. The spring 20 contracts until one end of the positioning plug plate 15 is separated from the limiting plug hole 8, and then the blocking device 5 is pulled to rotate inside the first limiting shaft hole 7 through the second rotating shaft 18, so that the warning poster 13 is exposed to the outside, and the positioning frames 27 at both ends slide inside the limiting card slot 23 until the two ends of the positioning frames 27 are separated from the side surfaces of the connecting block 14, and then the warning poster 13 is pulled to drive the connecting block 14 to separate from the inside of the plug slot 24. After the blocking device 5 is opened, it will be convenient for the staff to disassemble and replace the warning poster 13, thereby ensuring timely updating of the warning poster 13. When the warning poster 13 is replaced, the blocking device 5 is pulled to flip 90 degrees for reset, so that the blocking device 5 is engaged with the card slot 6.The force on the outer surface of the adjusting block 16 is then released, and one end of the positioning plate 15 will slide back under the elastic force of the first tensioning spring 20, so that one end of the positioning plate 15 is plugged into the limiting socket 8, thereby positioning the blocking device 5 after reset and sealing the card slot 6. By assembling and connecting the connecting device 21 and the connecting device 21, the clean room automatic door frame 2 can be flipped and adjusted, and the expansion range of the automatic door can be adapted and opened according to emergency situations. In addition, the warning and publicity device 4 is installed inside the fixed frame 3, which can facilitate the warning and publicity function inside the automatic door, thereby avoiding the waste of publicity resources for the automatic door.

[0035] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
