In this embodiment, one side fixed mounting of door frame 1 has guide lamp 7, and guide lamp 7 is located on door frame 1 and is close to top one side, and one side fixed mounting of door frame 1 has button 21, and button 21 passes through pencil 22 and electromagnet 17 looks electric connection, and the sustainable scintillation's of guide lamp 7 green light is convenient for people to discover and guide the exit, can terminate electromagnet 17's electric connection through button 21, makes set bar 20 and electromagnet 17 phase separation and break away from second door plant 3 and insert door frame 1 simultaneously.

In this embodiment, the peephole has been seted up on the second door plant 3, and the downthehole fixed mounting of peep has transparent peep board 5, and one side fixed mounting of first door plant 2 has sealing strip 6, and sealing strip 6 and one side looks adaptation of door frame 1 can direct observation indoor conditions be convenient for analyze and judge through peeping board 5, and sealing strip 6 can be sealed first door plant 2 and door frame 1's clearance, prevents that smog from diffusing to outdoors.

In this embodiment, the top side of the latch bolt 20 is provided with a locking rod 19, the locking rod 19 is rotatably installed on the inner side wall of the first door panel 2 through the second rotating shaft 14, one end of the locking rod 19 is matched with the side wall of the flange 15, and when the electromagnet 17 is powered off and then powered on again, one end of the locking rod 19 abuts against the flange 15, so that the latch bolt 20 cannot be automatically reset, and accidents caused by misoperation are prevented.

In this embodiment, one side fixed mounting of locking lever 19 has release link 13, and one side of first door plant 2 corresponds has seted up and has dodged the hole, and the one end of release link 13 runs through dodge the hole and extend to the lateral wall position department of first door plant 2, through pulling release link 13, makes the one end of locking lever 19 and flange 15 phase separation, and set bar 20 inserts second door plant 3 under the magnetic force effect of electro-magnet 17.

This practical theory of operation: the first door panel 2 is rotatably installed in the door frame 1, the first door panel 2 can be opened in a unidirectional rotation mode through the first hinge device 11 for daily use, the second door panel 3 embedded in the first door panel 2 can be opened in a bidirectional rotation mode through the second hinge device 10 for emergency passing, the length of the lock bolt 20 is the width between the second door panel 3 and the door frame 1, the lock bolt 20 can be inserted into one of the second door panel 3 or the first door panel 2, but can not be inserted into the second door panel 3 or the first door panel 2 at the same time, the electromagnet 17 generates magnetism and adsorbs the iron block 16 under the power-on state, the lock bolt 20 is taken out of the door frame 1 and inserted into the second door panel 3 at the same time, the second door panel 3 is locked while the first door panel 2 keeps the openable state, when the power is cut off, the first spring 18 allows the latch 20 to be withdrawn from the second door panel 3 while being inserted into the door frame 1, allowing the second door panel 3 to be opened while maintaining the first door panel 2 in the closed state.

The second door panel 3 rotates around the first door panel 2 through the first rotating shaft 103, the first rotating shaft 103 is located at the position of the symmetric center of the second door panel 3, the second door panel 3 can rotate towards two sides, the second springs 104 located at two sides of the fixing block 102 are symmetrically arranged along the first rotating shaft 103, the second door panel 3 automatically resets after the two second springs 104 reach balance under the action of elastic force after rotating for a certain angle, the decorative board 4 is arranged to cover avoiding spaces at two sides of the second door panel 3, the first connecting rod 101 and the second connecting rods 106 at two sides form a connecting rod mechanism after rotating for a certain angle, the second connecting rod 106 at one side close to the rotating direction is close to one end of the first connecting rod 101, and meanwhile, one end connected with the inner side wall of the decorative board 4 is contacted with the inner side wall of the decorative board 4 and the decorative board 4 is overturned for a certain angle, so that the second door panel 3 can smoothly rotate.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
