A lock plate 7 and an electromagnetic plate 8 are arranged on the inner surface of one side of the door frame 1. The electromagnetic plate 8 can magnetically fix the movable door body 3 when in use. The lock plate 7 can be inserted into the lock head 18 through the lock groove 9 when in use, and then the drive motor 11 can drive the drive wheel 12, so that the drive wheel 12 drives the driven wheel 13 to rotate through the transmission belt 14, and indirectly drives the driven wheel 13 to rotate the lock plate 7, so that the lock groove 9 and the lock head 18 can be misaligned to achieve the effect of locking and preventing slipping. When the drive motor 11 fails, the emergency door can be opened. The cover plate 6 can adjust the position of the reset lock disk 7 conveniently by manually rotating the driving wheel 12, so as to facilitate the disengagement of the lock head 18.

The lock disk 7 is located on both sides of the electromagnetic plate 8, and a lock groove 9 is arranged in the middle of the lock disk 7. An electric translation mechanism 10 and a driving motor 11 are arranged in the middle of the door frame 1. The electric translation mechanism 10 is located above the driving motor 11. The outer surface of one end of the driving motor 11 is detachably connected to the driving wheel 12, and the outer surface of one end of the lock disk 7 is fixedly connected to the driven wheel 13, and a transmission belt 14 is arranged between the driving wheel 12 and the driven wheel 13.

[0020] The utility model provides a heavy-duty radiation-proof door, in which a lock disk 7 is arranged which can be inserted into a lock head 18 through a lock slot 9 when in use, and then a drive motor 11 can drive a drive wheel 12, so that the drive wheel 12 drives a driven wheel 13 to rotate through a transmission belt 14, and indirectly drives the lock disk 7 to rotate by the driven wheel 13, so that the lock slot 9 and the lock head 18 can be misaligned to achieve a locking and anti-detachment effect. For example, when a failure of the drive motor 11 occurs, the emergency cover 6 can be opened, and the position of the lock disk 7 can be conveniently adjusted and reset by manually rotating the drive wheel 12, so that the lock head 18 can be disengaged.

[0022] In another embodiment provided by the utility model, a first built-in groove 15 and a second built-in groove 16 are provided in the middle of the movable door body 3, the first built-in groove 15 is located on one side of the second built-in groove 16, an electric push rod 17 is detachably connected to the inner surface of one end of the first built-in groove 15, a lock head 18 is detachably connected to the outer surface of one end of the electric push rod 17, a main retraction tube 19 is detachably connected to the inner surface of one end of the second built-in groove 16, and the electric push rod 17 can retract the lock head 18 when in use to facilitate the docking of the lock head 18 with the lock groove 9.

[0023] In another embodiment provided by the utility model, the middle part of the main shrinking cylinder 19 is movably connected to the auxiliary shrinking cylinder 20, the middle part of the auxiliary shrinking cylinder 20 is movably connected to the shrinking rod 21, the outer surface of one end of the shrinking rod 21 is fixedly connected to the fixing plate 22, the outer surface of one end of the auxiliary shrinking cylinder 20 is fixedly connected to the first baffle 23, the outer surface of the other end of the shrinking rod 21 is fixedly connected to the second baffle 24, a first limit spring 25 is arranged between the first baffle 23 and the main shrinking cylinder 19, and a second baffle 24 is arranged between the second baffle 24 and the auxiliary shrinking cylinder 20. There is a second limit spring 26, and the retracting rod 21 can be fixedly connected to the door frame 1 through the fixing plate 22. When the movable door body 3 is closed, the retracting rod 21 compresses the second limit spring 26 through the second baffle 24, and then the auxiliary retracting cylinder 20 compresses the first limit spring 25 through the first baffle 23. When the movable door body 3 is powered off, the first limit spring 25 and the second limit spring 26 rebound and reset, which can form a rear pulling force on the movable door body 3, making it easier to open the movable door body 3 and saving effort.

[0024] In an embodiment provided by the utility model, the number of lock disks 7 is two groups, the lock disks 7 and the lock slots 9 are an integrally formed structure, the driving wheel 12 is movably connected to the driven wheel 13 through a transmission belt 14, and the lock disks 7 mainly play a locking effect when in use.

[0026] It should be noted that the utility model is a heavy-duty radiation-proof door. When in use, the movable door body 3 is connected to the electric translation mechanism 10. Under the drive of the electric translation mechanism 10, the movable door body 3 can be translated. When the movable door body 3 needs to be closed, the electric push rod 17 can lead out the lock head 18, and then the movable door body 3 moves to make the lock head 18 docked in the lock groove 9. When the lock head 18 is inserted into the lock groove 9, the drive motor 11 is started. The drive motor 11 can drive the drive wheel 12, so that the drive wheel 12 drives the driven wheel 13 to rotate through the transmission belt 14, and indirectly drives the driven wheel 13 to rotate the lock disk 7, so that the lock groove 9 and the lock head 18 can be misaligned to achieve the effect of locking and preventing slipping. At this time, the side of the movable door body 3 is attached to the door frame 1, and the electromagnetic plate 8 electromagnetically absorbs the movable door body 3, which can achieve the effect of double locking of the movable door body 3. When the drive motor 11 fails, it can be opened. The emergency cover 6 can adjust the position of the reset lock disk 7 conveniently by manually rotating the drive wheel 12, so that the lock head 18 can be disengaged. It is safer when in use. In the case of power failure, the emergency cover 6 can be opened and the movable door body 3 can be opened by manually rotating the drive wheel 12, and the electromagnetic plate 8 loses its magnetic force and loses its magnetic property to the movable door body 3. At this time, the movable door body 3 can be pushed to open by the handle 5, and the retraction rod 21 can be fixedly connected to the door frame 1 through the fixing plate 22. When the movable door body 3 is closed, the retraction rod 21 compresses the second limit spring 26 through the second baffle 24, and then the auxiliary retraction cylinder 20 compresses the first limit spring 25 through the first baffle 23. When the movable door body 3 is in a power failure, the first limit spring 25 and the second limit spring 26 rebound and reset, which can form a rear pulling force on the movable door body 3, so that the movable door body 3 can be opened, which is more labor-saving and more practical.
