The power supply is electrically connected to the controller, and the controller is electrically connected to the angular displacement sensor 13 , the display screen 311 , the micro camera 12 and the receiver.

There are two situations when the logistics safety box is in use: First, when the staff presses the fingerprint on the fingerprint lock 11 and opens the box cover 20, the receiver will receive the wireless transmitter in the fingerprint lock 11. The unlock signal indicates that the safety box is normally unlocked. In this case, when the staff opens the box cover 20, although the ratchet wheel 31 will rotate, the display screen 311 will not work, and no value will appear on the display screen 311. Second, when an outsider forcibly destroys the fingerprint lock 11 and opens the box cover 20, the controller will not receive the unlock signal sent by the wireless transmitter in the fingerprint lock 11. The lower ratchet wheel 31 will rotate, so the receiver will separately receive the signal sent by the wireless angular displacement sensor 13 on the ratchet wheel 31 without receiving the unlock signal sent by the wireless transmitter in the fingerprint lock 11, indicating that the safety box is abnormally unlocked . At this time, the controller controls the micro-camera 12 to work together with the plurality of display screens 311 , and the micro-camera 12 captures the image data within this period of time. When the fingerprint lock 11 is destroyed, some subsequent passers-by may also open the box cover 20 for theft, so the wireless angular displacement sensor 13 will work many times. The number of times that 13 works is equal to the number of times that outsiders open the box cover 20 . Therefore, after abnormal unlocking, according to the working times of the wireless angular displacement sensor 13 , the controller will control the display screen 311 to work so that all the numbers displayed on the display screen 311 are equal to the working times of the wireless angular displacement sensor 13 . Each time the box cover 20 is opened, the ratchet wheel 31 will rotate by a certain angle under the action of the first pawl 36 and the second pawl 37 , so that one of the display screens 311 is just facing the display slot 15 .

After the staff comes back, by observing whether the fingerprint lock 11 is damaged, it can be determined whether the box has been opened by outsiders; by observing the numbers on the display screen 311 through the display slot 15, it can be determined that the box has been opened several times; The content of the information, you can watch the appearance of the outsider who opened the box, and then it is convenient for the police to obtain their identity information and hold them accountable.

In one embodiment, a cavity is formed inside the ratchet wheel 31, and the power source, the controller and the receiver are all fixedly arranged in the cavity. Since the display screen 311 is installed on the ratchet wheel 31 , the power supply, the controller and the receiver are all arranged in the cavity of the ratchet wheel 31 and rotate together with the ratchet wheel 31 , which can avoid the controller and the display screen 311 caused by the rotation of the ratchet wheel 31 . There are problems such as entanglement and knotting of the connecting wires between them. However, both the fingerprint lock 11 and the wireless angular displacement sensor 13 are wirelessly connected to the controller, so the above problems will not occur.

In one embodiment, a guide wheel 40 installed in the accommodating groove 14 is also included. The guide wheel 40 plays a guiding role for the rope body 35. After the rope body 35 bypasses the guide wheel 40, the above-mentioned one end thereof becomes a vertical state. This facilitates the longitudinal pulling of the guide rod 33 by the rope body 35 , so that the guide rod 33 will not be subjected to a lateral force, thereby making it move up and down in the guide hole 321 more smoothly. At the same time, the guide wheel 40 can also reduce the friction between the rope body 35 and the box body 10 .

In one embodiment, a telescopic rod disposed in the tension spring 38 is also included. Two ends of the telescopic rod are respectively fixedly connected with the first pawl 36 and the second pawl 37 . The telescopic rod is arranged in the tension spring 38 , which restricts the position of the tension spring 38 , which makes the extension and contraction of the tension spring 38 more stable, so that the first pawl 36 and the second pawl 37 have better cooperation during operation.

In one embodiment, a stopper 50 disposed in the display slot 15 is further included, and the stopper 50 is clamped with the slot wall of the display slot 15 . On the one hand, the design of the stopper 50 can hide the display slot 15, reduce the probability of outsiders finding the counting mechanism 30, and make them relax their guard; 14 cleaning.
