[0024] The surface of the housing 1 is fixedly provided with a limit block 12 on one side of the mounting block 6. The limit block and the outer surface of the rotating block 7 are both provided with through holes 13. Figure 4 In the state shown, the through hole 13 on the surface of the rotating block 7 will be aligned with the through hole 13 on the surface of the limit block. At this time, a lock (a common padlock in the prior art) can be inserted into the through hole 13, and then the rotating block 7 and the limit block 12 are locked together by the lock. At this time, as long as the rotating block 7 cannot rotate, it will not contact the lock of the box door 3; thereby preventing someone from opening the shell to modify the internal circuit of the shell, or modifying the internal program;
[0025] The surface of the door 3 is fixedly provided with a visual glass layer 14 outside the display screen 5, and the visual glass layer 14 can protect the display screen 5, and the display screen 5 of the device can display the user's usage information and cost situation, which is convenient for the user to query and manage;
[0026] The squeezing switch 10 is electrically connected to the alarm 11. When the squeezing switch 10 of the device is squeezed by the box door 3, the alarm 11 will not receive an electrical signal. When the squeezing switch 10 loses the squeezing of the box door 3, the alarm 11 receives an electrical signal. In this way, the alarm 11 can remotely transmit an alarm message to the control terminal.

[0027] An air flow channel 15 is fixedly provided on the surface of the housing 1, and an air outlet 16 is provided on the outer surface of the lower end of the air flow channel 15. The air of the device is deflected through the air flow channel 15 and then discharged from the air outlet 16. This ensures basic heat dissipation and ventilation, while ensuring that the air outlet 16 and the housing 1 are not directly connected, but have a bending angle, so as to prevent someone from inserting tools through the air outlet 16 to operate the components inside the housing 1;
[0028] A fan 17 is fixedly arranged on one side of the shell 1, and the fan 17 can accelerate the blowing of air to facilitate the discharge of hot air from the cavity flow channel and the air outlet 16, and then the outside air can be replenished into the shell 1 through the gap between the door 3 and the shell 1; this can play a role in cooling the components inside the shell 1.
[0029] Working principle: When using this device, the door 3 can be fixed by hooking the lock buckle 8 on the lock ear 9. Figure 5 As shown, in this state, it is only necessary to move the rotating block 7 so that the rotating block 7 rotates in a clockwise direction, so that the lock buckle 8 can hook the lock ear 9, so that the box door 3 can be fixed, and then the through hole 13 on the surface of the rotating block 7 will be aligned with the through hole 13 on the surface of the limit block 12. At this time, a lock (an ordinary padlock in the prior art will do) can be inserted into the through hole 13, and then the rotating block 7 and the limit block 12 are locked together by the lock. At this time, as long as the rotating block 7 cannot rotate, it will not contact the lock of the box door 3; thereby, it can prevent someone from opening the shell 1 to modify the internal circuit of the shell 1 or modify the internal program;
[0030] When the door 3 is closed, the squeeze switch 10 is squeezed. When someone pries the lock to open the door 3, the squeeze switch 10 loses the squeeze of the door 3. At this time, the alarm 11 can receive an electrical signal, so that the alarm 11 can remotely transmit an alarm message to the control terminal. At this time, the control terminal checks and if it is determined that no staff has gone to repair the device, it can be said that someone has maliciously opened the device, and the staff needs to inspect and check it in time to avoid unnecessary economic losses.
[0031] When the device is in use, the air outlet of the device is deflected through the air flow channel 15 and then discharged from the air outlet 16. This can ensure basic heat dissipation and ventilation while ensuring that the air outlet 16 and the shell 1 are not directly connected, but have a bending angle, which can prevent someone from inserting tools through the air outlet 16 to operate the components inside the shell 1.
