[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] As per the instruction manual Figure 1 , 2As shown in Figures 3, 4, and 5, the existing roller shutter door 1 is mainly locked by a floor lock 2 located in the middle of the bottom of the door curtain. However, with the development of intelligent technology, the floor lock 2 has gradually evolved into a multi-mode anti-theft lock that can be controlled by a key and remote electronic control. To prevent the floor lock 2 from being damaged, a hidden door lock reinforcement structure 3 is provided inside the guide rails on both sides of the roller shutter door 1. The door lock reinforcement structure 3 includes a housing 31, a card hook 32 located in the middle of the housing 31, an electric push rod 33 located at the hook face end of the card hook 32, and a tension spring 34 located on the hook face side of the card hook 32. The electric push rod 33 is a push rod without a self-locking structure to ensure that the card hook is locked. After the electric push rod 33 is de-energized, the single hook 32 will be pulled back to its original position by the tension spring 34. The top panel of the output shaft of the electric push rod 33 is a rectangular column, and the bottom side of the hook end of the card single hook 32 has push rod ear plates clamped on both sides of the rectangular column. The card single hook 32 is connected to the side wall of the housing 31 and the output shaft of the electric push rod 33 is connected to the hook end of the card single hook 32 by a pin structure. The push rod ear plates are located below the rotating pin column of the card single hook 32 to ensure the adjustment of the rotation angle of the card single hook 32. In order to limit the position of the card single hook 32 in the default state, the opening end of the housing 31 is provided with a limiting post 35 to limit the rotation angle of the hook end of the card single hook 32.

[0022] To facilitate the connection of the tension spring 34, the hook face of the card hook 32 is provided with ear plates 321 on the opposite side and the side wall of the housing 31, and the tension spring 34 is provided with hooks 341 passing through the holes of the ear plates 321 on both sides.

[0023] To facilitate manual opening of the door lock reinforcement structure 3 during power failure, synchronous slide bars 4 are provided on both sides of the output shaft of the electric push rod 33, passing through the side wall of the housing 31. An L-shaped groove 41 is provided inside the side wall of the housing 31 to restrict the sliding direction of the synchronous slide bars 4. A right-angle bolt 42 passing through the synchronous slide bar 4 is provided inside the L-shaped groove 41. The synchronous slide bar 4 is connected to both sides of the push rod lug of the output shaft of the electric push rod 33 via bolts, and the electric push rod 33 is connected to the bottom surface of the housing 31 via bolts. To facilitate the rotation of the right-angle bolt 42, a threaded post is provided at the flat end of the right-angle bolt 42, and a nut is fitted above the threaded post. To ensure the stability of the vertical end position of the right-angle bolt 42, the right-angle bolt 42 is positioned close to the bottom end of the L-shaped groove 41. To prevent the right-angle bolt 42 from falling into the housing 31 when its vertical end is engaged in the L-shaped groove 41, the vertical groove of the L-shaped groove 41 is a non-through hole.

[0024] The roller shutter door 1 has slots on both sides that engage with the single hook 32. When the roller shutter door 1 falls, the side wall of the slot presses against the inclined surface of the single hook 32, causing the single hook 32 to rotate forward, just like the telescopic rod of a normal door lock. After locking, the single hook 32 automatically resets under the action of the tension spring 34. When manual or remote opening is required, simply pull the right-angle bolt 42 or activate the electric push rod 33 to move the electric push rod 33 and the right-angle bolt 42 backward. After the roller shutter door 1 is opened, the electric push rod 33 is de-energized, and the single hook 32 automatically resets under the action of the tension spring 34.

[0025] To ensure the concealment of the synchronous sliding strip 4, the bottom surface of the guide rails on both sides of the roller shutter door 1 is provided with door lock grooves corresponding to the L-shaped grooves 41, and the door lock grooves are concealed by a concealed door lock. In order to facilitate remote control, the electric push rod 33 can be opened synchronously. The electric push rod 33 is connected to the remote electric control system of the floor lock 2 through a wire.

[0026] In practical implementation, staff inside or outside the door can remotely and electrically open the floor lock 2 and door lock reinforcement structure 3 of the roller shutter door 1 using a fingerprint lock or iris scanning lock. In the event of a power outage, the floor lock 2 can be opened with a key, and then the hidden door lock in the door lock groove below the guide rail can be opened. After that, the right-angle bolt 42 can be pulled back and the vertical surface of the right-angle bolt 42 can be locked in the non-through hole of the L-shaped groove 41. Finally, the roller shutter door 1 can be opened manually. After opening the roller shutter door 1, remember to reset the right-angle bolt 42 and close the hidden door lock.
