In the embodiment of the application, the door frame 10, the hinge mechanism 40, the door body 20, the door closer 30 and the power-off locking mechanism are arranged; the side edge of the door body 20 is rotatably connected with the door frame 10 through the hinge mechanism 40; the door closer 30 is arranged at the top of the door body 20 close to the side edge of the door frame 10, and the other end of the door closer 30 is installed on the door frame 10; the hinge mechanism 40 comprises a rotating shaft 41 fixedly connected with the door frame 10 and an outer ring 42 in rotating fit with the rotating shaft 41; the outer ring 42 is fixedly connected with the door body 20; the power-off locking mechanism comprises a sliding piece 54 arranged above the outer ring 42, a limiting ring 53 used for limiting the sliding of the sliding piece 54 in the vertical direction and an electromagnetic adsorption component used for releasing the sliding piece 54 when the power is off; a limiting hole 421 is arranged on the end surface of the outer ring 42; when the door body 20 is closed, the position of the limiting hole 421 corresponds to that of the sliding piece 54, the end part of the sliding piece 54 is in sliding fit in the limiting hole 421, so that the door body 20 is locked and cannot rotate after the anti-theft side hung door is closed, the anti-theft side hung door is prevented from being pushed by criminals, and the criminals can be caught conveniently by security personnel.

Next, a description will be further made of an antitheft side hung door in the present exemplary embodiment.

As an example, the power-off locking mechanism further includes a protection sleeve 55 fixed to the door frame 10; the electromagnetic adsorption component and the limiting ring 53 are both arranged inside the protective sleeve 55. Specifically, a containing cavity is arranged inside the protective sleeve 55; the electromagnetic adsorption component is fixed at the top of the accommodating cavity; the sliding part 54 is connected below the electromagnetic adsorption component in an adsorption manner; the limiting ring 53 is matched with the sliding part 54 in shape; one end of the limiting ring 53 is fixed at the top of the accommodating cavity through a connecting rod, and the other end of the limiting ring is sleeved outside the sliding part 54.

When the anti-theft side hung door is powered on, the sliding piece 54 is connected with the electromagnetic adsorption component in an adsorption manner; after the anti-theft side hung door is powered off, the sliding part 54 is separated from the electromagnetic adsorption component, and at this time, two conditions exist in the motion state of the sliding part 54, the first condition is as follows: if the sliding member 54 corresponds to the position of the position-limiting hole 421 (i.e., the sliding member 54 is located right above the position-limiting hole 421), the end of the sliding member 54 slides into the position-limiting hole 421, so as to lock the outer ring 42; the second case is: if the position of the sliding piece 54 does not correspond to the position of the limiting hole 421, the end of the sliding piece 54 slides to the surface of the outer ring 42 until the door body 20 is closed by pulling the door closer 30, the position of the sliding piece 54 corresponds to the position of the limiting hole 421, and the end of the sliding piece 54 slides to the inside of the limiting hole 421, so that the outer ring 42 is locked. It should be noted that, by providing the limiting ring 53, the sliding member 54 can be limited to move in the vertical direction, so as to avoid that when the outer ring 42 rotates, the surface of the outer ring 42 and the bottom of the sliding member 54 generate friction, thereby driving the sliding member 54 to rotate.

In this embodiment, the electromagnetic absorption assembly includes an electromagnet 51 fixed on the door frame 10 and a metal plate 52 fixedly connected with the sliding member 54; when the electromagnet 51 is electrified, the metal plate 52 is in adsorption connection with the electromagnet 51; when the electromagnet 51 is de-energized, the metal plate 52 is separated from the electromagnet 51, and the slider 54 vertically falls. The electromagnetic adsorption component can also comprise an electric push rod arranged at the top of the electromagnet 51; the electric push rod is used for driving the electromagnet 51 to move in the vertical direction, so that the sliding piece 54 is driven to move in the vertical direction. Specifically, when the end of the sliding member 54 is engaged with the limiting hole 421, the electric push rod drives the electromagnet 51 to move downward until the electromagnet 51 is connected to the metal plate 52 in an adsorbing manner, and then the electric push rod drives the electromagnet 51 to move upward until the sliding member 54 is separated from the limiting hole 421.

In this embodiment, the door frame 10 is further provided with a processor and a sound sensor 11; the processor is electrically connected with the electromagnet 51 and the sound sensor 11 respectively. Specifically, the processor may be a single chip microcomputer; the sound sensor 11 is configured to collect a sound signal and send the sound signal to the processor, and the processor is configured to receive the sound signal and identify whether an alarm signal exists in the sound signal (for example, a naive bayes model is used to perform feature identification on an audio frequency), and when the alarm signal exists, the processor is further configured to disconnect the electromagnet 51 from the power supply through a driver, so as to lock the outer ring 42. It should be noted that, in the present embodiment, the modules related to the circuit and the electronic component are all the prior art, and those skilled in the art can completely implement the present invention without needless to say.

In this embodiment, the door closer 30 is an electric door closer 30; the door closer 30 is electrically connected to the processor. Specifically, when the alarm signal exists, the processor is further configured to drive the door closer 30 to drive the door body 20 to close, so as to drive the limiting hole 421 to rotate to a position below the sliding part 54. It should be noted that, in the present embodiment, the modules related to the circuit and the electronic component are all the prior art, and those skilled in the art can completely implement the present invention without needless to say.

In this embodiment, the hinge mechanism 40 includes two or more hinge mechanisms; the power-off locking mechanism is arranged above each hinge mechanism 40; the rest parts except the door frame 10 are symmetrically provided with two parts. Specifically, the hinge mechanism 40 and the power-off locking mechanism on each side are provided with an upper group and a lower group.
