[0002] Face recognition is a biometric technology that identifies people based on their facial features. It uses a camera or a camera to collect images or video streams containing faces, and automatically detects and tracks faces in the images, and then performs a series of related technologies on the detected faces. It is also commonly called portrait recognition or facial recognition. Through small computer calculation and conversion, a 3D mathematical model of the face is established. The photo data recorded in the chip is compared with the photo taken by the camera at the border inspection office through a computer to confirm whether they are the same person. In the specific use of the existing temporary access control face recognition device, when the device is folded or unfolded, the user needs to open the support plates one by one. The steps are cumbersome and reduce the folding and unfolding efficiency of the recognition device. In order to solve the above problems, we propose a face recognition device for access control.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-7 As shown, a face recognition device for access control includes a base 1, the upper end of the base 1 is slidably connected to a sleeve 2, the lower end of the sleeve 2 is fixedly connected to a gravity block 3, four groups of power rods 5 are arranged on the outer side of the gravity block 3, the other ends of the four groups of power rods 5 are slidably connected to bottom legs 6, the inner side of the sleeve 2 is slidably connected to a column 9, the lower end of the column 9 is fixedly connected to the base 1, the upper end of the column 9 is fixedly connected to a connecting piece 10, and the upper end of the connecting piece 10 is fixedly connected to a face recognition screen 11.

[0022] In this embodiment, one side of the power rod 5 is rotatably connected to a rotating kit 7, the other side of the rotating kit 7 is fixedly connected to the gravity block 3, the other side of the power rod 5 is fixedly connected to a sliding rod 51, an installation groove 61 is provided on the outer side of the bottom leg 6, a sliding groove 52 is provided on the inner side of the installation groove 61, and the sliding rod 51 is adapted to the sliding groove 52.

[0023] Specifically, the gravity block 3 drives the power rod 5 to slide, which can conveniently drive the slide rod 51 to slide in the slide groove 52.

[0024] In this embodiment, the outer side of the power rod 5 is slidably connected with a ring 43, the upper end of the ring 43 is fixedly connected with a connecting block 42, the outer side of the connecting block 42 is fixedly connected with a first rotating shaft 41, the outer side of the first rotating shaft 41 is rotatably connected with a pull rod 4, and the upper end of the pull rod 4 is fixedly connected to the base 1.

[0025] Specifically, by rotating the connecting collar 43 at the lower end of the pull rod 4 , the power rod 5 can be easily slid inside the collar 43 .

[0026] In this embodiment, the upper end of the bottom leg 6 is fixedly connected to a second rotating shaft 62 , the outer side of the second rotating shaft 62 is rotatably connected to a connecting plate 63 , and one side of the connecting plate 63 is fixedly connected to the base 1 .

[0027] Specifically, the cooperation between the second rotating shaft 62 and the connecting plate 63 can facilitate the opening or contraction of the bottom leg 6 .

[0028] In this embodiment, a limiting hole 21 is provided on the outer side of the sleeve 2 , and a handle 22 is fixedly connected to the outer side of the sleeve 2 .

[0029] Specifically, by pulling the handle 22 , the sleeve 2 can be conveniently pulled.

[0030] In this embodiment, two groups of limit grooves 8 are opened on the outer side of the column 9, and the inner sides of the two groups of limit grooves 8 are fixedly connected with springs 81, and the other side of the spring 81 is fixedly connected with a sliding block 82, and the other side of the sliding block 82 is fixedly connected with a limit rod 83, and the limit rod 83 is adapted to the limit hole 21.

[0032] It should be noted that the utility model is a face recognition device for access control. The user first carries the device to the workplace, and then holds the column 9 with his hand, at which time he presses the limit rod 83. The force on the limit rod 83 will drive the sliding block 82 to squeeze the spring 81 and move inward, thereby releasing the limit hole 21 from limiting the limit rod 83. At this time, the gravity block 3 will drive the sleeve 2 to move downward under the action of gravity. The downward movement of the gravity block 3 will drive the power rod 5 to move downward. At this time, the power rod 5 will slide on the inside of the collar 43. Because the collar 43 and the pull rod 4 are rotatably connected, the collar 43 will be driven to rotate, and the power rod 5 will be rotatably connected to the rotating kit 7. , the power rod 5 will drive the sliding rod 51 to slide inside the sliding groove 52. At this time, the bottom leg 6 can be conveniently opened through the cooperation of the second rotating shaft 62 and the connecting plate 63. When the bottom leg 6 is opened, the limiting hole 21 provided on the outside of the sleeve 2 also moves to the position of the limiting rod 83 below. The limiting hole 21 is limited by the limiting rod 83, and then the sleeve 2 is locked. At this time, the column 9 is loosened, and the equipment can be fixed standing at the workplace. When the use of the device is over, pressing the limiting rod 83 can release the limit on the sleeve 2. At this time, pulling the handle 22 upwards can retract the bottom leg 6, which is convenient for carrying the device.
