Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0018] like Figures 1-5As shown, this utility model employs an island-head device with a safety warning function, comprising a chassis 1, an identifier mounted on the chassis 1, and a portable hard drive 2 disposed inside the chassis 1 and electrically connected to the identifier via a communication interface. The portable hard drive 2 is equipped with a U-shaped handle 9 for easy pulling, allowing operators to easily retrieve and place the hard drive. A mounting base 3 is fixed to the portable hard drive 2, and a base 4 is fixed to the side of the chassis 1 near the mounting base 3. The mounting base 3 and the base 4 are detachably connected via a rotary disassembly assembly. After opening the rotary disassembly assembly, the portable hard drive 2 can be removed, and after installing the portable hard drive 2, the rotary disassembly assembly can be closed to maintain a secure connection between the portable hard drive 2 and the chassis 1. The rotary disassembly assembly includes a rotary lock 5 rotatably connected to the mounting base 3 via a rotating shaft 52 and a locking groove 7 embedded inside the base 4. The rotary lock 5 includes a handle 51 and a locking block 6 disposed on the outer circumference of the rotating shaft 52, and the handle 51 and the locking block 6 are vertically distributed. When the rotary disassembly assembly is opened, the handle 51, the rotating shaft 52 and the locking block 6 rotate synchronously. A locking position 71 is provided in the middle of the arc-shaped surface inside the locking groove 7. The shape of the locking position 71 is adapted to the end of the locking block 6 away from the rotating shaft 52. The locking position 71 and the locking block 6 are magnetically locked by a fixed magnet. The fixed magnet includes a first magnet 72 and a second magnet 73 of equal size and both arc-shaped cylindrical bodies. The first magnet 72 is installed at the end of the locking block 6 away from the rotating shaft 52, and the second magnet 73 is installed on the locking position 71. The first magnet 72 and the second magnet 73 have opposite magnetic properties. Damping cups 8 are provided inside the locking groove 7 and on both sides of the second magnet 73. The damping cups 8 and the second magnet 73 on both sides are arranged in the direction of rotation of the first magnet 72. The damping cups 8 are hollow inside and undergo elastic deformation when compressed to achieve buffering and limiting, so as to further position the first magnet 72. The front of the chassis 1 has a display unit and a warning unit located below the display unit. The two work together to realize the functions of information display and safety warning. The display unit includes a camera 10 fixed to the top of the chassis 1 and an information display screen 11 below the camera 10. The camera 10 can collect images of the surrounding environment in real time, while the information display screen 11 is used to display key information such as the device's operating status and recognition results. The warning unit consists of a speaker 12 located below the information display screen 11, a warning screen 13 at the lower end of the speaker 12, and reflective strips 14 arranged in sections along the outer perimeter of the chassis 1. When the camera 10 detects an abnormal situation, the speaker 12 emits a voice warning, the warning screen 13 strengthens the reminder by flashing lights, and the reflective strips 14 can improve the visibility of the device by reflecting light in low-light environments, thus ensuring the safety of the device during use in all aspects. In addition, a maintenance door 15 is provided on the back of the chassis 1 for regular maintenance of the components inside the chassis 1.

[0019] Workflow: The portable hard drive 2 is initially locked to the chassis 1. At this time, the first magnet 72 on the locking block 6 and the second magnet 73 on the locking position 71 attract each other due to their opposite poles. The damping cup 8 is compressed and provides friction to further prevent the locking block 6 from moving. When it is necessary to remove the portable hard drive 2, hold the handle 51 and rotate it counterclockwise. As the rotation angle increases, the damping cup 8 above the second magnet 73 returns to its original shape and no longer generates resistance. The first magnet 72 and the second magnet 73 gradually separate. When the locking block 6 is completely disengaged from the locking position 71, the damping cup 8 below the second magnet 73 returns to its original shape. Under the action of gravity, the handle 51 rotates 90 degrees counterclockwise and then comes to a stop naturally. At this time, the locking block 6 is completely disengaged from the locking groove 7, and the portable hard drive 2 is unlocked from the chassis 1. The portable hard drive 2 can be removed through the U-shaped handle 9, and data reading or maintenance operations can be completed through the mobile device. After the operation is completed, insert the portable hard drive 2 into the chassis 1, then hold the handle 51 and rotate it 90 degrees clockwise. The locking block 6 rotates synchronously with the rotating shaft 52 and slides back into the locking position 71 of the locking groove 7. The first magnet 72 and the second magnet 73 gradually attract each other. The damping cup 8 is squeezed and deformed by the locking block 6, generating radial pressure to firmly fix the locking block 6. The rotary lock 5 returns to the initial locked state, and the portable hard drive 2 is fixedly connected to the chassis 1 without loosening or shaking.

No improvements have been made to their circuit connection structure and principle. Therefore, their circuit connection structure and principle will not be described in detail here.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
