[0022] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0023] Example 1

[0024] Reference Figure 1-5 As shown, a visual data acquisition device for a door access control system includes a mounting base 1 and a facial recognition device 2. The facial recognition device 2 is arranged at one end of the mounting base 1. An opening 7 is provided at the middle position of the inner surface of the mounting base 1. The upper and lower ends of the inner cavity of the opening 7 are rotatably connected with rotating shafts 9 that are symmetrically distributed. The outer circumference of the rotating shaft 9 is fixedly sleeved with a first gear 10. The outer parts of the two first gears 10 are meshed with a toothed belt 4. One side of one of the rotating shafts 9 passes through the mounting base 1 and extends out of the mounting base 1. The surface of the rotating shaft 9 extending out of the outer part of the mounting base 1 is fixedly sleeved with a first handle 12. The rear end of the facial recognition device 2 is provided with a U-shaped support frame 6. The upper and lower ends of the support frame 6 are fitted with a resistance plate 11. The resistance plate 11 One end is fixed to the outer surface of the toothed belt 4, and the limit rod 3 is fixed at the positions on the surface of the mounting seat 1 on both sides of the facial recognizer 2. The outer peripheral surface of the limit rod 3 is slidingly sleeved with a sliding sleeve 5, and the side of the sliding sleeve 5 close to each other is fixed to the surface of the support frame 6. Since the sliding sleeve 5 can slide along the outer peripheral surface of the limit rod 3 at the adjacent position, it can limit the movement trajectory of the limit rod 3. By rotating the first set handle 12 to rotate one of the first gears 10, the first gear 10 can drive the two contact plates 11 to move in the vertical direction, so that it can contact the support frame 6 to drive the facial recognizer 2 to move in the vertical direction, so that the height position of the facial recognizer 2 can be adjusted so that the device is suitable for users of different heights.

[0025] Please refer to Figure 2 , Figure 4 and Figure 5 As shown, both sides of the inner surface of the support frame 6 are rotatably connected with symmetrically distributed rotating shafts 13, and the sides of the rotating shafts 13 close to each other are fixed to the surfaces on both sides of the facial recognition device 2, and one side of one of the rotating shafts 13 passes through the support frame 6 and the sliding sleeve 5 in sequence and extends to a position on one side of one of the sliding sleeves 5. Through the connection relationship of the rotating shafts 13, the facial recognition device 2 can move along the vertical direction with the support frame 6, and the angle when it is connected to the support frame 6 can be adjusted.

[0026] Example 2

[0027] Further in the embodiments, please refer to Figure 4 and Figure 5As shown, two mounting blocks 14 are fixed on the surface of the top of one of the sliding sleeves 5, and a threaded rod 15 is rotatably connected at the middle position of the two mounting blocks 14. One end of the threaded rod 15 passes through one of the mounting blocks 14 and extends to the position of one end of the mounting block 14. A second sleeve handle 17 is fixedly sleeved at the position of the threaded rod 15 at one end of the mounting block 14. A threaded sleeve 16 arranged in an L shape is threadedly connected to the outer circumference of the threaded rod 15. The surface of one side of the threaded sleeve 16 is fixed to the surface of the rack 18. A limiting shaft 8 is inserted through the surface of the threaded sleeve 16 at the bottom position of the threaded rod 15. The surfaces at both ends of the limiting shaft 8 are fixed to the surfaces of the mounting blocks 14 at adjacent positions. The threaded rod 15 can be rotated by rotating the second sleeve handle 17. Since the threaded sleeve 16 is subject to the resistance and limiting effect of the limiting shaft 8 on it, the threaded sleeve 16 can only move in the horizontal direction. When the threaded rod 15 rotates, the threaded sleeve 16 can move in the horizontal direction under the cooperation between the internal thread structure of its inner wall and the external thread structure of the outer circumference of the threaded rod 15.

[0028] Please refer to Figure 4 and Figure 5 As shown, the rotating shaft 13 extends to the outer peripheral fixed sleeve at one side of the sliding sleeve 5 and is provided with a second gear 19, and a rack 18 is meshed on the top of the second gear 19. When the threaded sleeve 16 moves in the horizontal direction, it can drive the rack 18 to move in the horizontal direction, and under the meshing action between the rack 18 and the second gear 19, the rotating shaft 13 is rotated to adjust the angle when the facial recognizer 2 is connected to the sliding sleeve 5, so as to adjust the range of facial data collected by the facial recognizer 2.

[0029] Working principle: In actual use, when the user needs to adjust the height of the facial recognition device 2 to accommodate users of different heights, the first handle 12 is rotated to allow the rotating shaft 9 to rotate, so that one of the first gears 10 can rotate, so that the toothed belt 4 can move under the meshing action between the first gear 10 and the toothed belt 4, and the other rotating shaft 9 can rotate under the meshing action between the toothed belt 4 and the other first gear 10, so that the other rotating shaft 9 and the first gear 10 can support the toothed belt 4 so that the rotating shaft 9 can move more smoothly, so that the two contact plates 11 can move in the vertical direction, so that under the interference action between the two contact plates 11 and the support frame 6 and the connection action between the support frame 6 and the facial recognition device 2, the facial recognition device 2 is subjected to a vertical force, and due to the sliding sleeve 5 It can only slide along the outer circumference of the limit rod 3, so that the facial recognizer 2 can move in the vertical direction, thereby adjusting the height position of the facial recognizer 2. When it is necessary to adjust the angle at which the facial recognizer 2 is connected to the support frame 6, the threaded rod 15 can be rotated by rotating the second sleeve handle 17. Since the threaded sleeve 16 is limited by the resistance of the limit shaft 8, the threaded sleeve 16 can only move in the horizontal direction. When the threaded rod 15 rotates, the threaded sleeve 16 can move in the horizontal direction under the cooperation between the internal thread structure of its inner wall and the external thread structure of the outer circumference of the threaded rod 15 to drive the rack 18 to move in the horizontal direction, and under the meshing action between the rack 18 and the second gear 19, the rotating shaft 13 is rotated to adjust the angle at which the facial recognizer 2 is connected to the sliding sleeve 5, thereby adjusting the range of facial data collected by the facial recognizer 2.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
