DETAILED DESCRIPTION

[0016] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0017] See also Figure 1-Figure 3A face recognition access control machine includes a base 1; slide bars 2 are slidably arranged on both sides of the base 1, and a support base 3 is fixedly connected to the top of the slide bar 2. Side plates 4 are installed on both sides of the support base 3, and a rotating shaft 5 is rotatably arranged between the two side plates 4. An identification panel 6 is installed on the rotating shaft 5 for identifying a user, and an inner cavity 14 is opened in one of the side plates 4, and a rotating drum 7 is installed at one end of the rotating shaft 5 that penetrates the inner cavity 14. The outer wall of the rotating drum 7 is installed with equally spaced and annularly distributed latch teeth 8, and a limiting component is arranged in the inner cavity 14 for limiting the latch teeth 8. Under the action of the limiting component, the latch teeth 8 will be moved. The limit is set, at this time the shaft 5 cannot rotate, and the limiting component can limit the latch tooth 8 on one side, so that the shaft 5 can only rotate in one direction, thereby realizing one-way rotation. A lifting component connected to the support seat 3 is provided in the base 1, which is used to adjust the height of the support seat 3. The recognition height of the identification panel 6 can be adjusted by the provided lifting component, thereby satisfying users of different heights, thereby improving the practicality of the utility model, and when it is necessary to adjust the angle of the identification panel 6, the limiting component can be used to release the limiting of the latch tooth 8. At this time, the identification panel 6 can be rotated, and then the latch tooth 8 can be limited by the limiting component.

[0018] In one case of this embodiment, the limiting component includes two symmetrically distributed movable shafts 9 rotatably arranged in an inner cavity 14, a clamping rod 10 is installed on the movable shaft 9, two springs 11 respectively connected to the clamping rods 10 are arranged in the inner cavity 14, a transmission shaft 12 is rotatably arranged between the two clamping rods 10 in the inner cavity 14, a cam 13 fitted with the clamping rod 10 is installed on the transmission shaft 12, and in the initial state, the raised end of the cam 13 faces the rotating drum 7. The end of the transmission shaft 12 passing through the side plate 4 is installed with a rotating block 19. At this time, under the action of the spring 11, the two clamping rods 10 will be attached to the two sides of the cam 13. At this time, the two clamping rods 10 will be stuck in the clamping teeth 8 of the outer wall of the rotating drum 7. At this time, the rotating drum 7 cannot rotate, that is, the rotating shaft 5 cannot rotate, and then the angle of the identification panel 6 is limited. When it is necessary to rotate the rotating shaft 5, the rotating block 19 can be rotated, and the rotating block 19 will drive the transmission shaft 12 to rotate. When the transmission shaft 12 drives the cam 13 to rotate upward, the cam 13 will push the upper clamping rod 10, so that the clamping rod 10 moves out of the clamping teeth 8 of the rotating drum 7. At this time, Rotate the identification panel 6 to make the rotating shaft 5 rotate toward the side limited by the clamping rod 10. At this time, the rotating shaft 5 can only rotate in one direction. When it needs to rotate in the opposite direction, rotate the rotating block 19, and the rotating block 19 will drive the transmission shaft 12 to rotate. When the transmission shaft 12 drives the cam 13 to rotate downward, the cam 13 will push the clamping rod 10 below, so that the clamping rod 10 moves out of the clamping tooth 8 of the rotating drum 7. At this time, the identification panel 6 can be rotated toward the opposite line of defense, so that the rotating shaft 5 rotates toward the side limited by the clamping rod 10. At this time, the rotating shaft 5 can only rotate in one direction, and then the angle of face recognition can be adjusted according to the recognition requirements.

[0019] In one case of the present embodiment, the lifting component includes a sliding cavity 15 opened in the base 1, and the sliding cavity 15 is slidably connected to a sliding cylinder 16, and the top of the sliding cylinder 16 is connected to the support seat 3. A screw rod 18 is rotatably arranged in the sliding cavity 15, and the screw rod 18 is threadedly connected to the sliding cylinder 16. A motor 17 connected to the screw rod is installed in the base 1. When it is necessary to adjust the recognition height of the identification panel 6, the motor 17 is started, and the motor 17 drives the screw rod 18 to rotate, driving the sliding cylinder 16 to lift and lower, so that the support seat 3 is lifted and lowered, that is, driving the identification panel 6 to lift and lower. The lifting component can adjust the recognition height of the identification panel 6, thereby satisfying users of different heights and improving the practicality of the utility model.

[0020] The working principle of the utility model is as follows: when the rotating shaft 5 needs to be rotated during use, the rotating block 19 can be rotated, and the rotating block 19 will drive the transmission shaft 12 to rotate. When the transmission shaft 12 drives the cam 13 to rotate upward, the cam 13 will push the upper clamping rod 10, so that the clamping rod 10 moves out of the clamping tooth 8 of the rotating drum 7. At this time, the identification panel 6 can be rotated to make the rotating shaft 5 rotate toward the side limited by the clamping rod 10. At this time, the rotating shaft 5 can only rotate in one direction. When it is necessary to rotate in the opposite direction, the rotating block 19 is rotated, and the rotating block 19 will drive the transmission shaft 12 to rotate. When the transmission shaft 12 drives the cam 13 to rotate downward, the cam 13 will push the lower The card rod 10 makes the card rod 10 move out of the card tooth 8 of the rotating drum 7. At this time, the identification panel 6 can be rotated toward the opposite defense line, so that the rotating shaft 5 rotates toward the side limited by the card rod 10. At this time, the rotating shaft 5 can only rotate in one direction, and then the face recognition angle can be adjusted according to the recognition requirements; when the recognition height of the recognition panel 6 needs to be adjusted, the motor 17 is started, and the motor 17 drives the screw rod 18 to rotate, driving the sliding cylinder 16 to rise and fall, so that the support seat 3 is lifted and lowered, that is, driving the recognition panel 6 to rise and fall. The set lifting component can adjust the recognition height of the recognition panel 6, thereby satisfying users of different heights, thereby improving the practicality of the utility model.

[0021] The utility model can adjust the recognition height of the recognition panel 6 by setting a lifting component, thereby satisfying the needs of users of different heights, thereby improving the practicality of the utility model, and when it is necessary to adjust the angle of the recognition panel 6, the limit component can be used to release the limit on the latch tooth 8. At this time, the recognition panel 6 can be rotated, and then the latch tooth 8 can be limited by the limiting component.
