A lock core 12 is arranged on the side surface inside the slot 8, and the lock core 12 is connected with the slot 8 through 2 mechanical springs 11 in a welding mode. The pressure sensor 5 and the identification device 6 are mounted at the bottom of the lock cylinder 12. The side surface of the lock core 12 is in threaded connection with the pull rod 10 through a threaded hole, when the pull rod 10 is pulled outwards, the mechanical spring 11 contracts, and the bolt 14 starts to move upwards. Two ends of the 2 torsion springs 13 are respectively connected with the baffle 17 and the slot 8 through welding, when the bolt 14 moves to the top of the slot, the baffle 17 is extruded, the torsion springs 13 are bent at the moment, the baffle 17 is pushed open, and the bolt 14 can be taken out.
A through hole 16 is formed outside the slot 8, and data lines led out from the pressure sensor 5 and the recognition device 6 can be connected with the sub-controllers through the through hole 16.
When the bolt 14 is inserted into the slot 8, the partition plate 9 is pushed to compress downwards, and the upper part of the bolt 14 is tightly attached to the bottom of the lock cylinder 12 due to the action of the elastic force of the compression spring 7.
When the pressure sensor 5 at the bottom of the lock cylinder 12 senses a pressure change signal, the signal is input to a sub controller, the sub controller receives information of the pressure sensor 5 on each seat, generates an instruction to output the received information to the voice prompt device 2 and the indicator lamp 3, the indicator lamp is turned on, and related information is transmitted to the controller 1 and the terminal display 4. The controller 1 is installed in a crew duty room and controls the respective sub-controllers. A threshold value is preset on the pressure sensor 5, the pressure value is lower than the threshold value, the voice prompt device prompts that the safety belt is unlocked, and the indicator light displays red light; the pressure value is higher than the threshold value, the voice prompt device prompts that the safety belt is locked, and the indicator light displays green light.
After the information of the miniature two-dimensional code at the upper part of the bolt 14 is scanned by the recognition device 6, the information is input into the sub-controller through a data line, then the information is transmitted to the controller 1 for processing and then output to the terminal display 4, and the terminal display 4 displays the position of the safety belt. The terminal display 4 is installed in the attendant's duty room.
If no passenger is on the seat or the plane is in a flat flight state and the passenger does not fasten the safety belt, the power supply of the controller is cut off by the staff, and the controller stops working. At the moment, no matter whether the safety belt is fastened or not, the voice prompt device, the indicator lamp and the terminal display do not work and do not play a role in reminding.

2. When the bolt 13 is inserted into the slot 8, the lock core 12 is ejected, the partition plate 9 is pushed to compress the compression spring 7, and the compression spring 7 generates elasticity due to compression, so that the upper part of the bolt 14 is attached to the bottom of the lock core 12.
3. The pressure sensor 5 at the bottom of the lock cylinder 12 senses the pressure change and transmits a pressure change signal to the sub-controller.
4. When the contact between the lock tongue 14 and the lock cylinder 12 is good, the pressure value exceeds the threshold value, the sub-controller receives the signal and processes the signal and outputs the signal to the voice prompt device 2 and the indicator lamp 3, the voice prompt device 2 prompts that the safety belt is locked, and the indicator lamp 3 lights green light.
5. When the bolt 14 is in poor contact with the lock cylinder 12 or is not in contact with the lock cylinder, the pressure value is lower than the threshold value, the sub-controller receives the signal and processes the signal and outputs the signal to the voice prompt device 2 and the indicator lamp 3, the voice prompt device 2 prompts that the safety belt is not locked, and the indicator lamp 3 lights red light.
6. When the upper part of the bolt 14 is jointed with the bottom of the lock cylinder 12, the identification device 6 at the bottom of the lock cylinder 12 can immediately read the information of the miniature two-dimensional code positioned at the upper part of the bolt 14. The recognition means 6 inputs information into the partial controllers, which output the information via output ports to the controller 1 and the terminal display 4. The terminal display 4 displays the seat number where the seat belt is located. The crew can now quickly know which passenger is not buckled.
7. The pull rod 10 is pulled out, the mechanical spring 11 is compressed and the lock cylinder 12 gives the bolt an upward movement position. When the bolt 14 moves to the top of the slot 8, the baffle 17 is pressed, the torsion spring 13 bends, the baffle 17 is lifted upwards, and the bolt 14 is taken out.
When no passenger is on the seat, the power supply of the controller 1 is cut off, the controller 1 stops working, and the voice prompt device 2 and the indicator lamp 3 do not play a role in reminding. The terminal display 4 also stops operating.
Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that variations, modifications, substitutions and alterations can be made in the above embodiments by those of ordinary skill in the art without departing from the principle and spirit of the present invention.
