DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3 The face image recognition identity authentication device includes a base 1, the top surface of the base 1 is slidably connected to an assembly seat 8 through a lifting mechanism, the lifting mechanism includes a telescopic seat 7, and the telescopic seat 7 is fixedly installed on the top surface of the base 1, a telescopic rod 6 is slidably connected in the telescopic seat 7, and the other end of the telescopic rod 6 is fixedly connected to a rotating plate 10, a worm 17 is rotatably connected in the telescopic seat 7, and the worm 17 extends to the inside of the telescopic rod 6, and the worm 17 is threadedly connected to the telescopic rod 6, and the worm 17 is driven to rotate by a driving mechanism, the driving mechanism includes the telescopic rod 6, and a turning handle 5 is rotatably connected to the side of the telescopic seat 7, and one end of the turning handle 5 A worm wheel 18 is installed, and the worm wheel 18 is meshed with the worm 17. The other end of the turning handle 5 is sleeved with an anti-slip sleeve. The telescopic rod 6 is square in shape. It should be noted that the worm wheel 18 is driven by the turning handle 5 to drive the worm 17 to rotate. Then, the telescopic rod 6 is square, and the side wall of the telescopic seat 7 limits the worm 17 so that it cannot rotate, so that it slides up or down, so that the height of the assembly seat 8 can be adjusted to accommodate people of different heights. It is worth noting that the worm wheel 18 and the worm 17 are self-locking, and when the turning handle 5 stops, the height is also fixed;

[0022] The outer side of the assembly seat 8 is rotatably connected with a rotating plate 10 through a damping rotating shaft 16, and then the rotating plate 10 can be fixed at the angle after being rotated. Multiple display screens 9 and detection heads 11 are respectively installed on the side of the rotating plate 10. A fill light 12 is installed on the outer side of the detection head 11, and the fill light 12 is annular. The side of the rotating plate 10 is rotatably connected with a matte plate 15, which is adjusted to the direction of the sun or light source through the matte plate 15, so that the light source becomes soft and uniform through the matte plate 15, reducing the adverse effects of direct strong light or backlight on the detection head 11, thereby providing a more suitable lighting environment for face recognition, improving the accuracy and stability of recognition, and allowing the entire recognition process to proceed more smoothly;

[0023] The rotating plate 10 adjusts the rotation angle of the matte plate 15 through an adjustment structure. The adjustment mechanism includes a driven gear 13, and the driven gear 13 is rotatably connected in the rotating plate 10, and the matte plate 15 is fixedly installed on the outer side of the driven gear 13. The driven gear 13 and the inner wall of the rotating plate 10 are jointly installed with a spring gasket. The rotating plate 10 is rotatably connected with a driving gear 14, and the driving gear 14 is meshed with the driven gear 13. The pitch circle diameter length of the driving gear 14 is smaller than the pitch circle diameter of the driven gear 13. It should be noted that when the driving gear 14 rotates one circle, the driven gear 13 rotates one-sixth of a circle, thereby accurately adjusting the rotation angle of the matte plate 15. And through the setting of the spring gasket, the driven gear 13 can be fixed at the angle after being rotated to a certain angle;

[0024] A plurality of universal wheels 3 are symmetrically installed on the bottom surface of the base 1, and a plurality of fixing mechanisms are installed on the outer side of the base 1. The fixing mechanism includes a fixing seat 4, and the fixing seat 4 is fixedly installed on the outer side of the base 1. A threaded pin 2 is connected to the inner thread of the fixing seat 4, and a support pad is installed at the bottom end of the threaded pin 2. The universal wheels 3 are used to facilitate the movement of the device, and the support pad increases the contact area between the device and the ground, making its fixation more stable.

[0025] When the utility model is used, the device can first be moved to a designated position by the universal wheel 3, and then the threaded pin 2 can be lowered by rotating different fixing seats 4 to fix the device, and then the turning handle 5 can be rotated to drive the telescopic rod 6 to slide up or down through the setting of the worm 17 and the worm wheel 18, and then the height of the assembly seat 8 can be adjusted to accommodate people of different heights;

[0026] When the light is dim, the fill light 12 can be started to fill in the light for the detection head 11 to avoid blurring of the portrait captured by dim light. When strong light appears, the driving gear 14 can be rubbed to adjust the rotation angle of the driven gear 13, driving the matte plate 15 to rotate to the direction of the strong light, thereby making the light source soft and uniform, reducing the adverse effects of direct strong light or backlight on the detection head 11.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
