[0002] The full name of the anti-theft door is "anti-theft safety door". It has both anti-theft and safety performance. It can resist abnormal opening under certain conditions for a certain period of time and has certain safety protection performance. The flat-open fence anti-theft door is an anti-theft door used by ordinary middle-class family users according to the lighting requirements. It is not only simple and beautiful, with good lighting effect, but also allows direct observation from inside the door to the outside.

[0003] In the prior art, the patent document with the announcement number CN112647787B discloses a magnetic heat-insulating fire-proof anti-theft door, which includes a door body and a door frame, wherein the door body is movably mounted on the door frame through a hinge, and an anti-theft mechanism is arranged at the bottom of the door body and the inner wall at the bottom of the door frame. The middle-house anti-theft door with a lighting function is provided with an anti-theft mechanism. When a person is alone at home, the permanent magnet B is placed in the clamping groove cavity. When the door body and the door frame are closed, the plug block presses down the linkage plate and is clamped in the clamping groove under the magnetic attraction of the permanent magnet A and the permanent magnet B. The door body cannot be opened from the outside, thereby achieving a complete anti-theft effect and enhancing the safety factor of the anti-theft door. By providing a fixing rod and a limiting plate, the person at home can press the linkage plate on the inner side of the door frame with his foot, and the plug block is lifted from the clamping groove cavity through the limiting plate, thereby achieving automatic separation of the anti-theft mechanism. The structure is simple, which is convenient for a person alone at home to use and provides better safety protection.

[0004] During use, it was found that the above device could not circulate air indoors and outdoors, and its use had certain limitations. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a magnetic heat-insulating, fire-proof and anti-theft door.

[0006] A magnetic heat-insulating, fire-proof and anti-theft door of the present invention comprises a door body, a door frame, an electromagnetic lock, a sensor, a No. 1 lock hole and a No. 2 lock hole.

The mechanical lock component is installed inside the door body, and the ventilation component is arranged on the door body. When in use, the sensor is electrically connected to the electromagnetic lock and the mechanical lock component. When the door body seals the door frame, the sensor is blocked by the door frame, the electromagnetic lock is extended and inserted into the No. 1 lock hole, and then the mechanical lock component is plugged into the No. 2 lock hole to achieve double locking, improve security and anti-theft performance, and when it is necessary to interact outdoor and indoor air, open the ventilation component to allow indoor and outdoor air to interact, thereby improving flexibility and safety.

[0007] Preferably, the mechanical lock assembly includes a servo electric cylinder, a smooth rod, a moving seat, and a mechanical lock tongue. A cavity is provided inside the door body. Two smooth rods are provided in the cavity. A servo electric cylinder is installed in the cavity. A moving seat is installed at the telescopic end of the servo electric cylinder.

In the normal state, the first ventilation door seals the first ventilation opening in cooperation with the first shaft pin. At the same time, the straight clamping plate is inside the L-shaped clamping plate. Rotate the first bolt so that the first bolt inserts into the inner side of the round hole. When it is necessary to interact the indoor and outdoor air, rotate the first bolt to make the first bolt away from the round hole, and then make the straight clamping plate away from the L-shaped clamping plate, so that the first ventilation door releases the seal of the first ventilation opening, and then the indoor and outdoor air can be interacted.

[0009] Preferably, the sealing assembly includes a second ventilation opening, a second ventilation door, a locking bolt, a positioning frame, a strip-shaped opening, and a locking assembly.

Each group of locking bolts are respectively threadedly connected to the first ventilation door. A locking assembly is provided between the first ventilation door and the second ventilation door. When the first ventilation door is completely opened, external personnel can see the interior through the first ventilation opening, the first ventilation opening, and the anti-theft net, and the privacy is poor. It is possible to continue to keep the first ventilation opening sealed, and then make the second ventilation door open at a certain angle in cooperation with the second shaft pin. Then the locking bolt makes an adaptive position adjustment in the strip-shaped opening of the positioning frame, and at the same time the positioning frame makes an adaptive angle adjustment in cooperation with the locking bolt. After the adjustment is completed, rotate the locking bolt, and the locking bolt presses against the positioning frame to complete the fixation, realizing the interaction of indoor and outdoor air while improving the privacy.

One end of the plug board away from the spring is provided with a plug board, and the plug board is slidably connected to the square frame. When the second ventilation door needs to seal the second ventilation opening, the moving plate is moved downward, so that the plug board moves downward. After the second ventilation door seals the second ventilation opening, the moving plate is released, so that the moving plate drives the plug board to insert into the positioning groove under the action of the spring force, thus completing the locking of the second ventilation door.

[0011] Preferably, a chamfered portion is provided on the plug board; the plug board is quickly inserted into the positioning groove with the cooperation of the chamfered portion, improving the quick locking.
