DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] Please refer to Figures 1 to 6, the present utility model provides a technical solution: an access control and security device, including a base 1, two main units 7 are fixed on the base 1, a partition 2 is installed between the two main units 7, a limit and buffer structure is installed on the partition 2, a baffle 6 is rotatably fitted in the main unit 7, the baffle 6 corresponds to the limit and buffer structure, a pressing plate 10 and a limit block 11 are installed on the base 1, the limit block 11 corresponds to the pressing plate 10, the limit block 11 corresponds to the baffle 6, a U-shaped groove 12 is opened in the base 1, and the U-shaped groove 12 corresponds to the pressing plate 10 and the limit block 11.
[0024] In this embodiment, a rotating shaft 8 is rotatably fitted in the main unit 7, the rotating shaft 8 is fixedly connected to the baffle 6, the limit and buffer structure includes a limit plate 3, the limit plate 3 is fixedly connected to the partition 2, a buffer plate 4 is elastically connected to one side of the limit plate 3 close to the baffle 6, and a plurality of first springs 5 are fixed between the buffer plate 4 and the limit plate 3.
[0025] Specifically, when the baffle 6 is closed, the baffle 6 rotates until the baffle 6 contacts the buffer plate 4, and then the baffle 6 can be limited.
[0026] When the baffle 6 is impacted by a reverse force, the baffle 6 presses the buffer plate 4, causing the first spring 5 to be compressed, thereby buffering the baffle 6 and preventing the rotating shaft 8 from bending due to the pressure on the baffle 6.
[0027] A groove 15 is opened in the base 1, the groove 15 is communicated with the U-shaped groove 12, the groove 15 corresponds to the pressing plate 10, a pressing block 16 is fixed to the lower side of the pressing plate 10, the pressing block 16 corresponds to the U-shaped groove 12, the pressing block 16 and the limit block 11 are respectively located at both ends of the U-shaped groove 12, a second spring 13 is fixed between the pressing block 16 and the limit block 11 and the groove wall of the U-shaped groove 12, a first electrode plate 14 is fixed on the baffle 6, a second electrode plate is fixed on the limit block 11, the first electrode plate 14 corresponds to the second electrode plate, and a camera 9 is fixed on the main unit 7.
[0028] Specifically, when a pedestrian passes through the access control, the baffle 6 is in an open state. At this time, the pedestrian stands on the pressing plate 10, the pressing plate 10 presses down the pressing block 16, causing the second spring 13 below the pressing block 16 to be squeezed. The pressing block 16 pushes up the limit block 11 through air pressure, causing the limit block 11 to rise to one side of the baffle 6. At this time, the first electrode plate 14 contacts the second electrode plate, and then the baffle 6 can be physically limited by the limit block 11. The first electrode plate 14 and the second electrode plate can also be connected to a motor and an alarm. When the first electrode plate 14 contacts the second electrode plate, the motor is controlled to turn off. When the contact time between the first electrode plate 14 and the second electrode plate is too long, the alarm is controlled to give an alarm, which can better protect the pedestrian and prevent the pedestrian from occupying the walking passage for a long time.
[0029] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment contains only an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
