[0043] The sensing part 6 is arranged on the rotating part 3 and rotates synchronously with the rotating part 3. When the rotating end 22 is driven to rotate by the rotating part 3, the sensing part 6 can detect the locking position and the unlocking position of the locking part 2 in real time through the first sensing part 611 and the second sensing part 612, so as to monitor the locking state and the unlocking state of the USB interface in real time.

[0047] In this way, the structural space of the rotating piece 3 is reasonably utilized, the space is saved, the compactness between structures is improved, and the volume of the USB interface locking structure is reduced. Under the action of the mounting sleeve 62, the inductor 61 can be stably mounted on the rotating piece 3, so that the inductor 61 is stably driven to rotate when the rotating piece 3 rotates, the inductor 61 and the inductive module are stably magnetically inductive, the locking position and the unlocking position of the locking piece 2 are accurately detected, the monitoring of the USB interface locking or unlocking state is improved, and the management and monitoring of the management personnel are facilitated.

[0048] Referring to Figures 1 to 6 , the locking piece 2 is arranged in a bent structure, the shell 1 is provided with a through hole 13 for the locking piece 2 to pass through, and the locking piece 2 is provided with a convex shaft 26 on both sides, and the convex shaft 26 is rotationally connected with the hole wall of the through hole 13.

[0049] In this way, under the premise that the locking piece 2 can normally lock or unlock the USB interface, the locking piece 2 is arranged in a bent structure, the occupied space of the locking piece 2 is reduced, the space is saved, the bent design is more convenient for the rotation of the locking piece 2, the design is reasonable, and the volume of the USB interface locking structure is reduced.

[0051] By abutting the boss 221 against the abutting top 311, the rotating end 22 does not need to be in contact with the rotating member 3, in which case, the volume of the rotating end 22 of the locking member 2 can be reasonably designed or reduced to reduce the space occupied by the locking member 2 inside the shell 1. At the same time, the abutting boss 221 also facilitates abutting against the abutting top 311, so that the abutting top can stably drive the rotating end 22 of the locking member 2 to rotate to drive the locking portion 21 to extend out of or retract from the avoiding hole 123.

[0052] The USB interface locking structure further comprises a resilient member 7, one end of the resilient member 7 abutting against the shell 1, and the other end abutting against the rotating end 22, the resilient member 7 being used to provide a restoring force for resetting the locking member 2.

When the rotating member 3 rotates to the release position, the unlocking release slot 312 is used to release the rotation limitation of the rotating end 22.

[0059] After the plug 122 is inserted into the USB interface, the control board 5 receives the locking instruction sent by the external terminal device. The control board 5 controls the motor 4 to start working. The motor 4 drives the rotating member 3 to rotate. The rotating member 3 drives the locking abutting portion 311 to rotate, so that the locking abutting portion 311 gradually pushes against the abutting boss 221 to drive the rotating end 22 to rotate. The rotating end 22 compresses the elastic member 7 and drives the locking portion 21 to extend out of the avoiding hole 123. The locking portion 21 locks the USB interface to complete the locking of the USB interface.

[0060] When it is needed to unlock the USB interface, the control board 5 receives the unlocking instruction sent by the external terminal device. The control board 5 controls the motor 4 to start working. The motor 4 drives the rotating member 3 to rotate. The rotating member 3 drives the locking abutting portion 311 to gradually separate from the abutting boss 221. When the unlocking release slot 312 rotates to be aligned with the abutting boss 221, the unlocking release slot 312 can provide a space for the rotating end 22 to move, so as to release the limiting of the locking member 2. The rotating end 22 moves towards the rotating member 3 under the action of the elastic member 7, so that the locking member 2 can be reset, that is, the locking portion 21 separates from the USB interface and retracts into the avoiding hole 123 to release the locking of the USB interface, thereby completing the unlocking of the USB interface.

[0067] The shell 1 is provided with an annular avoiding groove 112 arranged around the electrical interface 111. The annular avoiding groove 112 is used for adapting to the shape of the computer key interface, so that the interface shape of more external terminal devices can be adapted, and the applicability of the USB interface locking structure is improved.
