The outer side of 10 is fixed with a bayonet, which is used in conjunction with the claw 9. The inner bottom of the temperature box 6 is fixedly connected with a coil 11, the inside of the coil 11 is slidably connected with a cutting block 12, and the inner top of the detection chamber 2 is fixedly connected with an alarm. 13. The inside of the temperature box 6 is fixedly connected with an electromagnet 14, the inner wall of the temperature box 6 is slidably connected with a top block 15, and the bottom of the top block 15 is fixedly connected with a buffer spring, so that the top block 15 will not delay the movement of the clamping rod 8, only Only when the electromagnet 14 is energized can the movement of the clamping rod 8 be restricted. The inwall of the frame 1 is fixedly connected with a transmission wheel 16, which is connected in transmission with the driving wheel 10, and the inwall of the transmission wheel 16 is slidably connected with a sliding tooth 17. One side away from the crank wheel 18 is fixedly connected with a limit spring to prevent the crank wheel 18 from reversing. The inside of the drive wheel 16 is fixedly connected with a crank wheel 18, and the outside of the crank wheel 18 is fixedly connected with a driving lever, which is used in conjunction with the sliding tooth 17 to prevent The crank wheel 18 rotates, and the inside of the crank wheel 18 is provided with a fan-shaped chute, so that the rotation of the crank wheel 18 becomes the linear motion of the pulley 19. The inside of the crank wheel 18 is slidably connected with a pulley 19, and the top of the pulley 19 is movably connected with a slide bar 20 , the slide bar 20 is slidably connected to the inside of the swing bar 21, so that the swing bar 21 has a larger swing range, the inner wall of the frame 1 is movably connected with the swing bar 21, and the outer sides of the swing bar 21 and the slide bar 20 are fixedly connected with a retaining net, The net is anti-theft, and can prevent sundries. The outside of the drive wheel 16 is engaged with a ratchet 22. The inside of the ratchet 22 is fixedly connected with a reel 23. The outside of the reel 23 is fixedly connected with a retaining net. The ratchet 24 is fixedly connected with a thrust spring on the outside of the ratchet 24, so that the ratchet 22 can rotate relative to the reel 23 without causing the rewinding to block the net.
[0028] Working principle: when the equipment is stolen, the equipment is damaged, the vibrating plate 4 vibrates, the vibrating plate 4 vibrates to drive the lever 3 to swing, the lever 3 swings and rubs against the friction block 5, and the friction block 5 makes the internal temperature of the temperature box 6 rise, and the temperature The mercury inside the box 6 is heated and expands, and the mercury drives the clamping rod 8 away from the driving wheel 10, and the clamping rod 8 drives the claw 9 away from the driving wheel 10. At this time, the driving wheel 10 rotates, and the driving wheel 10 rotates to drive the magnetic block to rotate. When the magnetic block rotates to When approaching the cutting block 12, the cutting block 12 moves to cut the magnetic induction line, so that the coil 11 is energized, and the alarm 13 is alarmed when the coil 11 is energized. The block 15 limits the clamping rod 8, and the drive wheel 10 rotates to drive the transmission wheel 16 to rotate, and the transmission wheel 16 rotates to drive the sliding gear 17 to rotate, and the rotation of the sliding gear 17 drives the crank wheel 18 to rotate through the driving lever, and the crank wheel 18 rotates to drive the pulley 19 moves, the pulley 19 moves to drive the slide bar 20 to swing, the slide bar 20 swings to drive the swing bar 21 to swing, when the swing bar 21 swings to figure 1 The position shown stops swinging, and the swing bar 21 stretches the net, and the net further prevents theft. When the drive wheel 16 rotates, it drives the ratchet 22 to rotate, and the ratchet 22 rotates to drive the ratchet 24 to rotate. Rotate, the reel 23 rotates and unclamps the net, can not interfere with the swing of the fork 21, and now the driving lever drives the sliding tooth 17 to move to the inside of the transmission wheel 16, and the sliding tooth 17 makes the crank wheel 18 not follow the transmission wheel 16 to rotate, and Ensure that the crank wheel 18 will not rotate. When the equipment needs maintenance, the equipment will be powered off, the driving wheel 10 will stop rotating, the coil 11 will be powered off, the alarm 13 will stop alarming, and the clamping lever 8 will reset under the action of the tension spring 7. Drive the claw 9 to reset, at this time, toggle the transmission wheel 16 to reverse, the transmission wheel 16 drives the crank wheel 18 to reverse, the crank wheel 18 reverses to drive the pulley 19 to reset, the pulley 19 drives the pendulum 21 to reset, and the transmission wheel 16 drives the ratchet 22 is reversed, and the ratchet 22 drives the reel 23 to reverse, and the reel 23 collects the retaining net to prevent the retaining net from interfering with the operation of the equipment.
[0029]To sum up, the anti-theft alarm self-service vending machine based on the Internet of Things drives the lever 3 to vibrate through the vibration of the vibrating plate 4, and the friction between the lever 3 and the friction block 5 increases the temperature inside the temperature box 6, and the liquid inside the temperature box 6 pushes the lever 8 moves, the clamp rod 8 drives the claw 9 to move, the claw 9 makes the driving wheel 10 rotate, the driving wheel 10 rotates and drives the cutting block 12 to move through the magnetic block on the front, and the cutting block 12 cuts the magnetic field lines inside the coil 11 to generate electricity , and then through the cooperative use of the coil 11 and the alarm 13, the effect of automatically alarming according to the vibration is achieved. The anti-theft alarm self-service vending machine based on the Internet of Things drives the transmission wheel 16 to rotate through the rotation of the driving wheel 10, the transmission wheel 16 drives the sliding tooth 17 to rotate, the sliding tooth 17 drives the crank wheel 18 to rotate, the crank wheel 18 drives the pulley 19 to move, and the pulley 19 Drive the sliding bar 20 to swing, and then through the cooperation of the sliding bar 20 and the swinging bar 21, the effects of preventing sundries from entering the equipment and facilitating later maintenance are achieved, and the scope of application is wider.
