When in the locked state, the fixed frame 51 is rotated to one side of the spring telescopic plate 41, and the extended end of the spring telescopic plate 41 is clamped in the slot 55 of the fixed frame 51. Because the fixed frame 51 cannot move up and down, the position of the horizontal plate 42 remains unchanged. At this time, the microphone end 57 and the front end plate are both in a locked state. In this state, the equipment can be prevented from being maliciously damaged by humans. When it needs to be opened, the fixed frame 51 is rotated to the other side, and the slot 55 of the sound shielding cover 52 is clamped with the spring telescopic plate 41. The sound shielding cover 52 is manually pulled downward, and the horizontal plate 42 moves downward synchronously. The tooth plate 44 engages with the second gear 47 to drive the fourth bevel gear 46 to engage with the third bevel gear 45, and then synchronously drives the front baffle 21 to open, and the microphone end 57 is pulled out and the identification screen 22 is exposed synchronously, which is more convenient to use.

[0034] In this embodiment, the cleaning component 3 also includes a gear ring 31, the gear ring 31 is fixed to the outer side of the top shaft ring of the fixed frame 51, and the bottom of the access control body 2 is located on one side of the gear ring 31 and is rotatably installed with a first gear 32, the first gear 32 is meshed and connected with the gear ring 31, and a first bevel gear 33 is fixed to the bottom of the first gear 32, a fixing plate 35 is fixed to the side of the access control body 2, and the bottom of the fixing plate 35 is rotatably installed with a second bevel gear 34 through a bearing toward the first bevel gear 33, the first bevel gear 33 is meshed and connected with the second bevel gear 34, a socket 310 is fixed to the top of the fixing plate 35, and the outer surface of the fixing plate 35 A transmission belt 36 is installed at the position corresponding to the socket 310 and the second bevel gear 34, and the two pulleys of the transmission belt 36 are fixedly connected to the socket 310 and the second bevel gear 34. A movable groove 37 is provided on the inner surface of the front baffle 21, and a cleaning strip 38 slides inside the movable groove 37. A screw 39 is rotatably installed at the bottom of the movable groove 37 through a bearing, and the cleaning strip 38 is threadedly sleeved on the surface of the screw 39. An arc plate 312 is fixed to one end of the screw 39 that passes through the front baffle 21. A transverse arc groove 311 is provided inside the socket 310, and the arc groove 311 has the same rotation path as the front baffle 21. The arc plate 312 is slidably plugged in Inside the arc groove 311, due to the inclination angle of the fixing plate 35, the screw 39 and the second bevel gear 34 can be transmitted through the inclined transmission belt 36. When the front baffle 21 covers the surface of the identification screen 22, the arc plate 312 of the screw 39 is just inserted into the arc groove 311 of the socket 310. At this time, when the fixing frame 51 is manually rotated, the cleaning cotton 56 on the inside of the fixing frame 51 rotates and wipes around the microphone end 57, and the gear ring 31 is meshed with the first gear 32 for transmission, so that the first bevel gear 33 is meshed with the second bevel gear 34, and then the socket 310 is rotated through the transmission of the transmission belt 36. Because the arc plate 312 and the arc groove 311 are When the screw 39 is engaged, it will also rotate synchronously. At this time, the cleaning strip 38 moves along the movable groove 37 as the screw 39 rotates to wipe the identification screen 22. This process can be performed when the fixed frame 51 is rotated and locked with the spring telescopic plate 41, or when the fixed frame 51 and the spring telescopic plate 41 are unlocked, that is, before or after using the access control body 2, the microphone end 57 and the identification screen 22 need to be wiped and cleaned to maintain the identification clarity. Because the arc groove 311 has the same rotation path as the front baffle 21, when the front baffle 21 is flipped open with the switch assembly 4, the arc plate 312 can slide out from the inside of the arc groove 311 without movement interference.

[0035] When using the device, pull the microphone end 57 downward, the electric reel 24 unwinds the connecting wire, the identification screen 22 opens synchronously, recognizes the face and voice of the person, and realizes the opening of the door. After use, wipe and clean the identification screen 22 and the microphone end 57 through the cleaning component 3 to prevent dust accumulation from affecting the clarity of recognition. In the locked state, rotate the fixed frame 51 to one side of the spring telescopic plate 41, and the extended end of the spring telescopic plate 41 is clamped in the slot 55 of the fixed frame 51. Because the fixed frame 51 cannot move up and down, the position of the horizontal plate 42 remains unchanged. At this time, the microphone end 57 and the front end plate are both in a locked state. In this state, it can prevent the device from being maliciously damaged by humans. When it needs to be opened, rotate the fixed frame 51 to the other side, and the slot 55 of the sound shielding cover 52 is clamped with the spring telescopic plate 41. Pull the sound shielding cover 52 downward manually. , the horizontal plate 42 moves downward synchronously, the tooth plate 44 meshes with the second gear 47 to drive the fourth bevel gear 46 to mesh with the third bevel gear 45, and then synchronously drives the front baffle 21 to open, pull out the microphone end 57 and expose the identification screen 22 synchronously, which is more convenient to use. Because of the inclination angle of the fixing plate 35, the screw rod 39 and the second bevel gear 34 can be transmitted through the inclined transmission belt 36. When the front baffle 21 covers the surface of the identification screen 22, the arc plate 312 of the screw rod 39 is just Plug into the arc groove 311 of the socket 310. When the fixed frame 51 is manually rotated, the cleaning cotton 56 inside the fixed frame 51 rotates and wipes around the microphone end 57, and the gear ring 31 is meshed with the first gear 32 to make the first bevel gear 33 mesh with the second bevel gear 34. Then, through the transmission of the transmission belt 36, the socket 310 rotates. Because the arc plate 312 is connected with the arc groove 311, the screw 39 also rotates synchronously. At this time, the cleaning strip 38 moves along the inside of the movable groove 37 as the screw 39 rotates, and the identification screen is cleaned. 22 is wiped, and the process can be carried out when the fixed frame 51 is rotated and locked with the spring telescopic plate 41, or when the fixed frame 51 is unlocked from the spring telescopic plate 41, that is, before or after using the access control body 2, the microphone end 57 and the identification screen 22 are wiped and cleaned to maintain the recognition clarity, because the arc groove 311 has the same rotation path as the front baffle 21, so when the front baffle 21 is flipped open with the switch assembly 4, the arc plate 312 can slide out from the inside of the arc groove 311 without movement interference.
