[0022] The anti-theft mechanism includes a mounting groove 4, a cargo opening 5, a horizontal baffle 6, a vertical baffle 7, a mounting cavity 8 and a transmission structure. The front end of the cargo picking cavity 3 is provided with a mounting groove 4, and the vertical baffle 7 is installed inside the mounting groove 4. The cargo opening 5 is provided at the bottom of the vending machine body 1, and the horizontal baffle 6 is installed inside the cargo opening 5. The mounting cavity 8 is installed inside the vending machine body 1. The transmission structure includes a servo motor 9, a first bevel gear 10, a second bevel gear 11, a first threaded rod 12, a first threaded sleeve 13, a second threaded rod 14, and a second threaded sleeve 15. The servo motor 9 is installed at the bottom end of the installation cavity 8, and a first bevel gear 10 is installed at the bottom end of the installation cavity 8. The output end of the servo motor 9 is connected to one end of the first bevel gear 10, and a second bevel gear 11 is meshed above the first bevel gear 10. A first threaded rod 12 is installed at one end of the second bevel gear 11, and a first threaded sleeve 13 is provided on the outer side wall of the first threaded rod 12. One end of the first threaded sleeve 13 is connected to one end of the transverse baffle 6, and a second threaded rod 14 is installed at the top of the first bevel gear 10. The outer wall of the second threaded rod 14 is provided with a second threaded sleeve 15, one end of which is connected to one end of the vertical baffle 7. When in use, when a customer buys something, the item falls from the unloading port 5 into the interior of the picking cavity 3, and the servo motor 9 is started to drive the first bevel gear 10 to rotate. Since the first bevel gear 10 and the second bevel gear 11 are meshed with each other, the first bevel gear 10 is used to drive the second threaded rod 14 to rotate, and the second bevel gear 11 is used to drive the first threaded rod 12 to rotate, thereby driving the second threaded sleeve 15 and the first threaded sleeve 13 to rotate respectively. Therefore, under the limitation of the first limiting rod 16, the first limiting sleeve 17, the second limiting rod 18 and the second limiting sleeve 19, the second threaded sleeve 15 is used to drive the vertical baffle 7 to move upward to open the picking cavity 3, and the first threaded sleeve 13 is used to drive the horizontal baffle 6 to move forward to close the loading port 5. At this time, the customer can take the goods out from the inside of the picking cavity 3, and cannot put his hand into the inside of the vending machine body 1 through the loading port 5, so that the vending machine body 1 is anti-theft treated, so that the anti-theft effect of the vending machine body 1 when in use is better, thereby greatly improving the practicability of the device when in use.
[0023] The limiting structure includes a first limiting rod 16, a first limiting sleeve 17, a second limiting rod 18 and a second limiting sleeve 19. The first limiting rod 16 is installed at the bottom end of the installation cavity 8, and the outer wall of the first limiting rod 16 is provided with a first limiting sleeve 17. One end of the first limiting sleeve 17 is connected to one end of the horizontal baffle 6. The second limiting rod 18 is installed at the top of the installation cavity 8. The outer wall of the second limiting rod 18 is provided with a second limiting sleeve 19. One end of the second limiting sleeve 19 is connected to one end of the vertical baffle 7. The two ends are connected, the cross-section of the first limiting rod 16 is smaller than the cross-section of the first limiting sleeve 17, and a sliding structure is formed between the first limiting rod 16 and the first limiting sleeve 17. When in use, the first limiting rod 16 and the first limiting sleeve 17 cooperate with each other to limit the transverse baffle 6 when it moves, so that the transverse baffle 6 is more stable when it moves. The second limiting rod 18 and the second limiting sleeve 19 cooperate with each other to limit the vertical baffle 7 when it moves, so that the vertical baffle 7 is more stable when it moves.
[0024] The installation cavity 8 is designed to be L-shaped, and the installation cavity 8 is symmetrically distributed inside the vending machine body 1 .
[0025] The alarm mechanism includes an alarm chamber 20, a vibration sensor 21 and an alarm 22. The alarm chamber 20 is opened inside the vending machine body 1. The vibration sensor 21 is installed at the bottom of the alarm chamber 20, and the alarm 22 is installed at the top of the alarm chamber 20. The front end of the alarm chamber 20 is provided with a cover plate. When in use, the vibration sensor 21 is adjusted to an appropriate value. When a thief violently damages the vending machine body 1, the vending machine body 1 is vibrated, and then the vibration sensor 21 is vibrated, and the signal is transmitted to the controller 2. At this time, the controller 2 controls the alarm 22 to alarm, warn the thief and remind the merchant, so that the anti-theft effect of the vending machine is better.
[0026] Working principle: in the initial state, the vertical baffle 7 is at the bottom, at this time, the vertical baffle 7 closes the vertical outlet of the vending machine, and the horizontal baffle 6 is at the far left, which opens the space above the vending machine and the pickup cavity 3. When a customer buys something, the item falls from the cargo port 5 to the inside of the pickup cavity 3. At this time, the servo motor 9 is started to drive the first bevel gear 10 to rotate. Since the first bevel gear 10 and the second bevel gear 11 are meshed with each other, the first bevel gear 10 is used to drive the second threaded rod 14 to rotate, and the second bevel gear 11 is used to drive the first threaded rod 12 to rotate, thereby driving the second threaded sleeve 15 and the first threaded sleeve 13 to move respectively. Therefore, under the limitation of the first limiting rod 16, the first limiting sleeve 17, the second limiting rod 18 and the second limiting sleeve 19, the second threaded sleeve 15 is used to drive the vertical baffle 7 to move upward to open the pickup cavity 3, and the first threaded sleeve 13 is used to drive the horizontal baffle 6 to move to the right to close the cargo port 5. The movement mode of this process is Figure 4 Towards Figure 3 The vending machine body 1 is protected from theft by adjusting the vibration sensor 21 to an appropriate value. When a thief violently damages the vending machine body 1, the vending machine body 1 is vibrated, which in turn causes the vibration sensor 21 to vibrate and transmit a signal to the controller 2. At this time, the controller 2 controls the alarm 22 to sound an alarm, alerting the thief and reminding the merchant, thereby improving the anti-theft effect of the vending machine.
