[0023] In the present application, the control unit can be the host server of the device or an independent processing unit of the device. By connecting the first sensor 7, the second sensor 10, and the servo motor 1, the control of the first sensor 7, the second sensor 10, and the servo motor 1 is realized. Specifically, the first sensor 7, the second sensor 10, and the servo motor 1 can be connected to the control unit in a wireless manner. In addition, the first sensor 7, the second sensor 10, and the servo motor 1 can also be connected to the control unit in a wired manner.

[0024] The servo motor 1 is a driving device. By controlling the rotation of the output shaft of the servo motor 1, the gear 13 can be driven to rotate.

The induction piece 8 is used to sense the distance between it and the first sensor 7, so as to determine whether the bolt 4 is successfully inserted into the third guiding hole on the second docking plate 15.

[0026] In this application, when the warehouse door is not allowed to be opened, for example, when the equipment is working, the second sensor 10 fixed on the first docking plate 11 detects whether the male catch 15 and the female catch 9 are completely closed to determine whether the warehouse door is closed in place; after receiving the signal that the warehouse door is closed in place sent by the second sensor 10, the control unit sends a locking signal to the steering gear 1; after receiving the locking signal, the output shaft of the steering gear 1 starts to rotate, the output shaft of the steering gear 1 drives the gear 13 to rotate, the gear 13 drives the rack 12 to move, the rack mounting seat 6 drives the bolt 4 to move, and the bolt 4 passes through the second guiding hole and is inserted into the third guiding hole; the first sensor 7 and the induction piece 8 detect whether the bolt 4 is inserted into the third guiding hole. When the bolt 4 is inserted into the third guiding hole, the bolt 4 has a binding effect on the second docking plate 14, and the male catch 15 and the female catch 9 cannot be decoupled, so the warehouse door cannot be opened.

[0027] When the warehouse door is allowed to be opened, the control unit sends an unlocking signal to the steering gear 1; after receiving the unlocking signal, the output shaft of the steering gear 1 drives the gear 13 to rotate, the gear 13 drives the rack 12 to move, the rack mounting seat 6 drives the bolt 4 to move, and the bolt 4 slowly disengages from the third guiding hole until the bolt 4 returns to its original position. When the bolt 4 has no binding effect on the second docking plate 14, the warehouse door can be opened by decoupling the male catch 15 and the female catch 9.

[0028] In addition, the bolt 4 in this application is fixed on the rack mounting seat 6 and moves along with the movement of the rack mounting seat 6. There are many ways to fix the bolt 4. Specifically, the bolt 4 can be fixed on the rack mounting seat 6 with screws. As one of the preferred embodiments, a fourth guiding hole can be provided on the rack mounting seat 6, and the bolt 4 is fixedly installed on the rack mounting seat 6 by passing through the fourth guiding hole on the rack mounting seat 6. Further, a fifth guiding hole corresponding to the position of the fourth guiding hole can also be provided on the support seat 3 of this application, and the bolt 4 passes through the fifth guiding hole and is supported on the support seat 3.
