[0023] The present invention will now be further described with reference to the accompanying drawings.

[0024] Please see Figures 1-7 An anti-theft warehouse metal door includes a metal door body 1 and a door frame 2. The metal door body 1 and the door frame 2 are hinged together. The lock on the outside of the metal door body 1 is used for normal daily use and also serves as a handle. A slide rail 3 is provided inside the metal door body 1. A push plate 4 is slidably connected to the inner wall of the slide rail 3. The slide rail 3 is used for moving the push plate 4 and connecting plate 8. A toothed plate 5 is connected to one side of the push plate 4. A support shaft 6 is rotatably connected to the inner wall of the metal door body 1. A gear 7 is connected to one end of the support shaft 6 inside the slide rail 3. The gear 7 meshes with the toothed plate 5. The gear 7 drives the toothed plate 5 to move. When the toothed plate 5 moves, it drives the push plate 4 to move at the same time. The push plate 4 pushes the connecting plate 8 to move the insert plate 9.

[0025] One end of the push plate 4 is connected to the connecting plate 8, and one side of the connecting plate 8 is connected to the insert plate 9. The end of the insert plate 9 away from the connecting plate 8 has an inclined angle. The inclined angle of the insert plate 9 facilitates the movement of the locking block 12. The outer surface of the insert plate 9 is slidably connected to the stop block 10, and the outer surface of the stop block 10 is slidably connected to the inner wall of the slide 3.

[0026] A first spring 11 is provided on the outside of the stop block 10. The first spring 11 is sleeved on the outside of the first guide rod 19. One end of the first spring 11 is connected to one side of the stop block 10, and the other end of the first spring 11 is connected to the inner wall of the connecting plate 8. The first spring 11 provides power for the stop block 10 to disengage from the connecting plate 8. The elastic support of the first spring 11 creates a gap between the stop block 10 and the connecting plate 8. At the same time as the gap is created between the connecting plate 8 and the stop block 10, the insert plate 9 is disengaged from contacting the locking block 12.

[0027] A locking block 12 is slidably connected to the inner wall of the stop block 10. A second spring 13 is provided inside the stop block 10. The second spring 13 is sleeved on the outside of the second guide rod 22. One end of the second spring 13 is connected to the inner wall of the stop block 10, and the other end of the second spring 13 is connected to the outer surface of the slide plate 21. The second spring 13 provides power for the locking block 12 to reset. After the locking block 12 is pushed out of the stop block 10 by the insert plate 9, it simultaneously drives the slide plate 21 to move. While the slide plate 21 moves, it compresses the second spring 13. The compressed second spring 13 provides power for the locking block 12 to reset.

[0028] The inner side of the locking block 12 is provided with a sliding groove 14. The inner wall of the sliding groove 14 is slidably connected to one end of the insert plate 9 at an inclined angle. The inner side of the door frame 2 is provided with a stop groove 15. The inner wall of the stop groove 15 is in contact with the outer surface of the stop block 10. The inner side of the door frame 2 is also provided with a locking groove 16. The inner wall of the locking groove 16 is in contact with the outer surface of the locking block 12. After the insert plate 9 contacts the sliding groove 14, it pushes the stop block 10 to move from the inside of the stop block 10 to the outside. After the position is moved, the stop block 10 contacts the stop groove 15.

[0029] A motor 17 is installed on one side of the metal door body 1. The output shaft of the motor 17 is connected to the end of the support shaft 6 away from the gear 7. The motor 17 provides power to the support shaft 6 to rotate. The rotation of the support shaft 6 drives the gear 7 to rotate at the same time. The motor 17 is started by internal control. The controller controls the forward and reverse rotation of the motor 17 by receiving remote control signals.

[0030] A protective cover 18 is also connected to one side of the metal door body 1, and the protective cover 18 is located outside the motor 17. The protective cover 18 activates the protection function outside the motor 17 to prevent the goods from touching the motor 17 during transfer, thereby improving the safety of the motor 17.

[0031] The stop block 10 is located on one side of the connecting plate 8 and is connected to the first guide rod 19. The outer surface of the first guide rod 19 is slidably connected to the inner wall of the connecting plate 8. The end of the first guide rod 19 away from the stop block 10 is connected to the limit block 20. The first guide rod 19 provides support for the stop block 10 and maintains the stability of the stop block 10. The limit block 20 limits the distance that the stop block 10 can move and prevents the stop block 10 from driving the first guide rod 19 out of contact with the connecting plate 8 under the push of the first spring 11.

[0032] The outer surface of the locking block 12 is connected to a sliding plate 21, and the outer surface of the sliding plate 21 is slidably connected to the inner wall of the stop block 10. The inner wall of the stop block 10 is connected to a second guide rod 22, and the outer surface of the second guide rod 22 is slidably connected to the inner wall of the sliding plate 21. When the locking block 12 moves to reset inside the stop block 10, one side of the locking block 12 has an inclined angle. After moving inside the stop block 10, it loses support and is supported inside the sliding plate 21 by the second guide rod 22. The sliding plate 21 provides support for the locking block 12 and maintains the stability of the locking block 12 when it moves.

[0033] In use, the following steps are taken: First, close the metal door body 1. Then, start the motor 17. After the motor 17 rotates, it drives the gear 7 to rotate through the support shaft 6. At the same time, the gear 7 rotates and drives the toothed plate 5 to move. Simultaneously, the toothed plate 5 pushes the push plate 4 to move, and the push plate 4 pushes the connecting plate 8 to move. As the connecting plate 8 moves, it drives the insert plate 9 to move. With the support of the first spring 11 on the stop block 10, the stop block 10 is pushed to move. After the stop block 10 contacts the stop groove 15, it stops moving. At the same time, the connecting plate 8 pushes the insert plate 9 to continue moving. The first spring 11 is compressed between the connecting plate 8 and the stop block 10. After the insert plate 9 continues to move, it contacts the sliding groove 14 inside the locking block 12. The insert plate 9 pushes the locking block 12 to move to the outside of the stop block 10. Then, the locking block 12 contacts the locking groove 16. At the same time, the sliding plate 21 moves and the sliding plate 21 compresses the second spring 13. When it is necessary to release the contact between the locking block 12 and the locking groove 16, the operation is reversed.
