All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] As Figures 1 to 6 shown, this embodiment provides an anti-shake face recognition device, which includes a base 1. A lifting structure 2 is provided on the top of the base 1. The lifting structure 2 includes a column 21 fixedly connected to the middle of the top of the base 1. Rectangular sliding grooves 22 are opened on both sides of the inner wall of the column 21.

A threaded groove is opened at the bottom of the lifting column 24, and the screw 26 is threadedly connected to the threaded groove. By starting the motor 25 to drive the screw 26 to rotate, the screw 26 drives the lifting column 24 to move up and down. At this time, the slider 23 slides in the rectangular sliding groove 22 to limit the lifting plate, facilitating the adjustment of the height of the face recognition device.

[0042] Above the lifting structure 2 is a turntable 3. A rotating structure 4 is provided between the lifting structure 2 and the turntable 3. The rotating structure 4 includes a support plate 41 fixedly connected to the top of the lifting column 24. A motor 42 is fixedly installed in the middle of the top of the support plate 41.

It has a good buffering effect and can effectively buffer and eliminate the force generated by the jitter.

[0044] An installation structure 7 is arranged inside the buffer structure 5. The installation structure 7 includes a fixing plate 71 fixedly connected to the top of the installation plate 57. A groove 72 is opened on the front side of the fixing plate 71. Card slots 73 are opened on both sides of the inner wall of the groove 72. Clamping blocks 74 are arranged on both sides of the face recognition device body 6. The clamping blocks 74 are used in cooperation with the card slots 73, so that the contour of the fixing plate 71 and the face recognition device body 6 match each other, which is convenient for the quick disassembly and assembly of the face recognition device body 6. A limiting groove 75 is opened on the top of the installation plate 57. A rectangular ring 76 is arranged outside the fixing plate 71. Sliders 77 are arranged on both sides of the rectangular ring 76. The sliders 77 are slidably connected in the rectangular sliding grooves 56. A limiting block 78 is arranged at the bottom of the rectangular ring 76. The limiting block 78 is used in cooperation with the limiting groove 75. Among them, magnetic sheets that are magnetically connected to each other are arranged at the bottom of the limiting block 78 and the bottom of the inner wall of the limiting groove 75. And a handle is arranged on the front side of the rectangular ring 76. The clamping blocks 74 are used in cooperation with the card slots 73 to limit and fix the upper and lower sides of the face recognition device body 6. The limiting block 78 is used in cooperation with the limiting groove 75 to limit and fix the front and rear sides of the face recognition device body 6, so that the face recognition device body 6 can be firmly fixed after installation.

[0045] On the front and back sides and the middle parts of the left and right sides of the top of the base 1, cylinders 8 are fixedly installed. The bottom of the cylinder 8 penetrates through the base 1. The output end of the cylinder 8 is fixedly connected with a support block 81. Anti-slip patterns 82 are provided at the bottom of the support block 81. Universal wheels 9 are provided at the four corners of the bottom of the base 1. By extending the cylinder 8, the support block 81 at its bottom contacts the ground, causing the universal wheels 9 to be separated from the ground and the base 1 to contact the ground, facilitating the suspension of the universal wheels 9 when the face recognition device body 6 is working. By using the anti-slip patterns 82 at the bottom of the support block 81, the contact friction between the support block 81 and the ground can be increased, thereby avoiding the displacement of the device during face recognition and improving the stability of the device.

[0046] In the specific implementation of the present utility model, during use, first, the staff pushes the device to the designated position, and then starts the cylinder 8 to drive the support block 81 to contact the ground, causing the universal wheels 9 to be separated from the ground and the base 1 to contact the ground, avoiding the displacement of the device during face recognition. Then, start the first motor 25 to drive the screw 26 to rotate, and the screw 26 drives the lifting column 24 to move up and down to adjust the height of the face recognition device. After that, the second motor 42 can be started to drive the turntable 3 and the connecting rod 44 to rotate on the annular groove 43, thereby driving the face recognition device body 6 to rotate, facilitating the adjustment of the face recognition angle. When the face recognition device shakes due to external environmental interference during operation, the shake generated by the face recognition device body 6 is transmitted to the mounting plate 57 through the fixing plate 71. At this time, through the combined use of the damping shock-absorbing rod two 59 and the spring two 510, the shake generated on the upper and lower sides of the face recognition device body 6 is buffered. At the same time, the mounting plate 57 can transmit the generated shake to the housing 53 and the T-shaped slider 52, and through the combined use of the damping shock-absorbing rod one 54 and the spring one 55, the shake generated on the left and right sides of the face recognition device body 6 is buffered, having a good buffering effect, effectively buffering and eliminating the force generated by the shake, and avoiding the phenomenon of image blurring caused by the shake of the face recognition device body 6. When it is necessary to remove the face recognition device body 6 for maintenance, slide the rectangular ring 76 upward in the rectangular chute two 56 through the handle, so that the limit block 78 is separated from the limit groove 75, then remove the rectangular ring 76, and then take out the face recognition device body 6 from the groove 72. After that, re-embed and install the maintained face recognition device body 6 into the groove 72 and reset the rectangular ring 76 to complete the installation, facilitating the quick disassembly and assembly of the face recognition device body 6, improving the stability of the device during operation, solving the trouble of the staff, meeting the needs of the staff, and improving the practicability of the device.
