[0026] Embodiment

[0027] Please refer to Figures 1-4, An access control device based on the Internet of Things, including a bottom plate 1. Two vertical plates 2 are symmetrically and fixedly installed at the top end of the bottom plate 1. The top ends of the two vertical plates 2 are fixedly connected by a top plate 3. A rotating shaft 4 is rotatably installed between the bottom plate 1 and the top plate 3. A plurality of rotating plates 5 are symmetrically and fixedly installed on the outer side wall of the rotating shaft 4. A guard plate 6 is fixedly installed on the outer side wall of each rotating plate 5. A limiting mechanism is arranged at the bottom end of the top plate 3; The limiting mechanism includes a connecting plate 7. The connecting plate 7 is fixedly installed at the bottom end of the top plate 3. The bottom end of the connecting plate 7 is fixedly installed with an inclined plate 9 through a spring 8. The inclined plate 9 is attached to the top area of the outer side wall of the rotating plate 5. A cylinder 10 is fixedly installed at the bottom end of the top plate 3. The output end of the cylinder 10 is attached to the outer side wall of the rotating plate 5; A telescopic column 12 is fixedly installed at the bottom end of the connecting plate 7. A fixed column 13 is slidably installed at the bottom end of the telescopic column 12. The bottom end of the fixed column 13 is fixedly connected to the top end of the inclined plate 9. The telescopic column 12 and the fixed column 13 are both located inside the spring 8. Through the sliding operation of the telescopic column 12 and the fixed column 13, the spring 8 performing telescopic operation is limited. A protective cover 15 is fixedly installed at the top end of the top plate 3 through a plurality of support columns 14. Through the installation of the support columns 14 and the protective cover 15, the device is protected.

[0028] Please refer to Figures 1-4 , An access control card reader 11 is fixedly installed on the outer side wall of one of the vertical plates 2. The access control card reader 11 is signal-connected to the cylinder 10. For this access control device based on the Internet of Things, the access control card reader 11 transmits signals to the cylinder 10. The bottom end of the cylinder 10 outputs power, so that the output end of the cylinder 10 is separated from the rotating plate 5. While rotating the rotating plate 5, the rotating shaft 4 is synchronously driven to rotate. While the rotating plate 5 rotates, the inclined surface of the inclined plate 9 is attached to the outer side wall of the rotating plate 5. Then, through the expansion and contraction of the spring 8, the inclined plate 9 is synchronously driven to slide with one of the rotating plates 5. By contacting pedestrians with two adjacent rotating plates 5, after the device is opened, only one pedestrian can pass by, preventing subsequent people from following the pedestrians who have already entered the device, improving the safety of the device and its practicality.

[0029] Please refer to Figure 4 , It should also be noted that a handle 16 is fixedly installed on the outer side wall of each rotating plate 5. By installing the handle 16, it is convenient for the user to rotate the rotating plate 5.

[0030] Please refer to Figure 1 , A sunshade 17 is fixedly installed at the top end of the access control card reader 11. By installing the sunshade 17, it is convenient to protect the access control card reader 11.

[0031] Please refer to Figure 3, a plurality of through holes 18 are formed in each rotating plate 5. By forming the through holes 18, it is convenient to perform weight reduction operations on the rotating plate 5 and convenient for users to rotate the rotating plate 5.

[0032] In summary, when the access control device based on the Internet of Things is in use, the access control card is brought into contact with the access control card swiping plate 11. The access control card swiping plate 11 transmits signals to the air cylinder 10. Power is output from the bottom end of the air cylinder 10, so that the output end of the air cylinder 10 is separated from one of the rotating plates 5. After a pedestrian passes through the two rotating shafts 4, the pedestrian rotates around the rotating shaft 4 under the limitation of the guard plate 6, so that the pedestrian passes through the device. While the rotating plate 5 rotates, the inclined surface of the inclined plate 9 is attached to the outer side wall of the rotating plate 5, so that the inclined plate 9 slides on the outer side wall of the rotating plate 5. While the inclined plate 9 moves, the spring 8 is compressed synchronously. When the flat surface of the inclined plate 9 contacts the outer side wall of the other rotating plate 5, after the pedestrian passes through the device, the rotating plate 5 can be limited.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
