[0023] like Figures 1 to 5As shown, the utility model is a door control device, comprising: a door control body 101, a display 102, a protective cover 103, a mounting block 104, a keypad 105, a controller 106, a support frame 107, a fixing seat 108, an identification hole 109, an opening and closing component 200 and an identification component 300. The display 102 is fixedly installed on the right side of the door control body 101, and the mounting block 104 is symmetrically fixedly installed on the side of the door control body 101 away from the closing component 200. The support frame 107 is fixedly installed inside the door control body 101. A controller 106 is fixedly mounted on the frame 107, a fixing seat 108 is fixedly mounted on the top of the controller 106, a keypad 105 is evenly fixedly mounted on the lower end of the outer wall surface of the access control body 101 close to the opening and closing component 200, and a protective cover 103 is installed on the top hinge of the keypad 105; the opening and closing component 200 includes a fixing frame 202, the fixing frame 202 is fixedly mounted on the side of the access control body 101 close to the keypad 105, the limit rod 205 is fixedly mounted in the fixing frame 202, and the moving block 203 is slidably arranged on the fixing frame 202. On the limit rod 205, a pressing piece 206 is fixedly installed on the side of the moving block 203 away from the door control body 101, a shielding piece 201 is fixedly installed on the top of the moving block 203, and a spring 204 is fixedly installed between the bottom of the inner wall of the fixed frame 202 and the moving block 203; the identification component 300 includes a T-block 302 and a moving frame 304, the T-block 302 is fixedly connected to the moving block 203, the T-block 302 is slidably set in the T-slot 301, and the T-slot 301 is set on the inner wall of the door control body 101 near the moving block On the side of 203, the T-block 302 and the movable frame 304 are fixedly installed with aligned movable seats 305 at both ends, and a rotating rod 306 is rotatably set on the movable seat 305. The movable frame 304 is slidably set on the outer wall of the fixed seat 108, and the inner end of the bottom of the movable frame 304 passes through the limiting groove 307 to be fixedly connected to the side wall of the pupil camera 303. An identification hole 109 aligned with the pupil camera 303 is set on the outer wall of the access control body 101, and the controller 106 is electrically connected to the pupil camera 303 and the keyboard 105.

[0024] In actual use, the user presses the pressing piece 206, and the pressing piece 206 drives the moving block 203, and the moving block 203 drives the blocking piece 201 to no longer block the identification hole 109. The moving block 203 moves and compresses the spring 204. The moving block 203 drives the T-block 302 to slide in the T-slot 301, and the T-block 302 drives the rotating rod 306 to rotate through the moving seat 305. The moving frame 304 slides in the limit groove 307 under the tension, and the moving frame 304 drives the pupil camera 303 to move, so that the pupil camera 303 moves to the identification hole 109 on the access control body 101, and the user's eyes are aligned with the identification hole 109. The pupil camera 303 shoots and identifies the user's pupil. After releasing the pressing piece 206, the spring 204 pushes the moving block 203, and the blocking piece 201 blocks the pupil camera 303.

[0025] Furthermore, the shielding sheet 201 is slidably set in the groove 207, and the groove 207 is set on the side of the access control body 101 to align with the fixed frame 202. The thickness of the shielding sheet 201 is the same as the depth of the groove 207. The groove 207 prevents the shielding sheet 201 from injuring the user's eyes when it accidentally bounces back. The limit rod 205 is vertically fixed in the fixed frame 202, so that the moving block 203 slides up and down along the limit rod 205.

[0026] Furthermore, limiting grooves 307 are symmetrically arranged on both sides of the outer wall of the fixing seat 108 , and the length of the limiting grooves 307 is smaller than the distance between the pupil camera 303 and the shielding sheet 201 , so as to prevent the pupil camera 303 from extending out of the identification hole 109 .

[0027] Working principle: the user presses the pressing piece 206, the pressing piece 206 presses down the moving block 203, the moving block 203 drives the shielding piece 201 to no longer block the identification hole 109, the moving block 203 moves down and compresses the spring 204, the moving block 203 drives the T-block 302 to slide down in the T-slot 301, the T-block 302 drives the rotating rod 306 to rotate through the moving seat 305, the moving frame 304 slides in the limit slot 307 under the tension, the moving frame 304 drives the pupil camera 303 to move, so that the pupil camera 303 moves to the identification hole 109 on the access control body 101. In the identification hole 109, the user's eyes are aligned with the identification hole 109, and the pupil camera 303 photographs and identifies the user's pupil. After releasing the pressing piece 206, the spring 204 pushes the moving block 203, and the shielding piece 201 shields the pupil camera 303 to prevent the surface of the pupil camera 303 from being in contact with the outside air for a long time, resulting in a decrease in clarity. In the event of eye discomfort, the user can use the password to unlock the fingerprint. The unlocking status can be intuitively understood through the display 102, which solves the problem of a large number of staff and unclear fingerprints, and is simple to operate and highly secure.
