[0033] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0034] Please see Figures 1-7This utility model provides a building access control terminal, including an access control device 001, a limiting device 002, and a limiting device 303. The access control body 100 is supported and limited by the limiting block 200 and the limiting block 300. The support block 120 is fixedly installed on the rod of the rotating rod 340. When the hand grips the ball 510 to pull the pull rod 500, it drives the transmission component 400 to rotate. The transmission component 400 drives the worm gear 341 to rotate, thereby causing the access control body 100 to change angle. The upper end of the access control body 100 tilts downward, which facilitates the camera 110 to capture and recognize the face of the patient in the wheelchair.

[0035] The access control device 001 includes an access control body 100. A camera 110 is installed at the front end of the access control body 100 for facial recognition. Support blocks 120 are fixedly installed at the lower rear end of the access control body 100 to support the access control body 100 in conjunction with a rotating rod 340. A limiting hole 121 is formed in the middle of the support block 120, and the support block 120 is fixedly fitted onto the left and right ends of the rotating rod 340, so that when the rotating rod 340 rotates, it synchronously drives the access control body 100 to change angle. A mounting block 130 is fixedly installed at the upper rear end of the access control body 100, and a magnetic block a131 is fixedly installed inside the mounting block 130. Magnetic blocks a131 and b241 attract each other, making the access control body 100 more stable when reset.

[0036] A limiting device 002 is installed above the rear end of the access control device 001 to limit its movement. The limiting device 002 includes a limiting block 200, with an expansion tube 210 installed at the rear end of each limiting block 200. The expansion tube 210 is fixedly installed inside the wall. A bolt 220 is installed in the middle of the expansion tube 210, and a nut 230 is fitted in the middle of the bolt 220 to control the expansion tube 210 in fixing the limiting block 200. The nut 230 is positioned at the limit... Inside the limiting block 200, a washer 211 is fitted in the middle of the bolt 220. When installing the limiting block 200, a cavity is first opened in the wall, and then the expansion tube 210 is installed in the cavity. A cavity is opened at the rear end of the limiting block 200 for the bolt 220 to pass through, so that the limiting block 200 can be close to the wall. The front end of the bolt 220 is inside the limiting block 200. Then, a washer 211 is fitted in front of the bolt 220, and the limiting block 200 is fixed to the wall by the nut 230.

[0037] Mounting block 240 is fixedly installed in the middle of limiting block 1 200, and magnetic block b241 for attracting magnetic block a131 is fixedly installed inside mounting block 240. When the access control body 100 is parallel to the wall, magnetic block b241 and magnetic block a131 attract each other to stabilize the access control body 100.

[0038] The lower rear end of the access control device 001 is equipped with a limit device 2003, which is used to cooperate with the limit device 002 to support and limit the limit device 2003. The limiting device 2003 includes a limiting block 200. Each limiting block 200 has an expansion tube 210 installed at its rear end. A bolt 220 is installed in the middle of each expansion tube 210. A nut 230 is fitted onto the middle of each bolt 220 to control the expansion tube 210 in fixing the limiting block 200. The nut 230 is located inside the limiting block 200. When installing the limiting block 200, a cavity is first opened in the wall, and then the expansion tube 210 is installed in the cavity. A cavity is opened at the rear end of the limiting block 200 for the bolt 220 to pass through, allowing the limiting block 200 to be close to the wall. The front end of the bolt 220 is inside the limiting block 200. A washer 211 is fitted onto the front end of the bolt 220, and then the limiting block 200 is fixed to the wall using the nut 230.

[0039] The middle of the second limiting block 300 is hinged with a rotating rod 340 for supporting the access control body 100. A worm gear 341 is fixedly installed in the middle of the rotating rod 340. The lower end of the second limiting block 300 is provided with a limiting groove 350 to facilitate the rotation of the support block 120. This makes it less likely that the support block 120 will hit the lower end of the second limiting block 300 when it rotates downwards, as the rotating rod 340 drives the support block 120 to rotate.

[0040] A transmission assembly 400 is hinged to the middle of the limiting block 300 to control the angle change of the access control body 100 in conjunction with the worm gear 341. The transmission assembly 400 includes a rotating rod 410. A helical tooth 411 for controlling the rotation of the worm gear 341 is fixedly installed on the outer wall of the rotating rod 410. An inner cavity 412 for the extension and retraction of the pull rod 500 is opened inside the rotating rod 410. A limiting hole 413 is opened at the lower end of the groove of the inner cavity 412. A helical groove 414 is opened on the upper inner wall of the inner cavity 412. A return spring 420 for controlling the return of the pull rod 500 is installed at the lower end of the inner cavity 412. When the slider 520 moves downward, it drives the slider 521 to slide in the groove of the helical groove 414, so that the rotating rod 410 moves forward synchronously. The rotating rod 411 drives the spiral gear 411 to rotate, which in turn drives the worm gear 341 to rotate, which in turn drives the rotating rod 340 to rotate. This causes the rotating rod 340 to drive the support block 120 to rotate, and the mounting block 130 to move away from the mounting block 240, causing the access control body 100 to change angle, which facilitates the camera 110 to perform facial recognition on the patient. When the patient does not pull the pull rod 500, the reset spring 420 pushes the slider 520, causing the slider 520 to move from the lower end of the inner cavity 412 to the upper end of the inner cavity 412, which in turn drives the rotating rod 410 to rotate in the opposite direction, causing the spiral gear 411 to drive the worm gear 341 to rotate in the opposite direction, which in turn drives the rotating rod 340 to drive the access control body 100 to reset.

[0041] A pull rod 500 for controlling the rotation of the transmission assembly 400 is installed in the middle of the transmission assembly 400. A grip ball 510 for pulling the pull rod 500 is installed at the lower end of the pull rod 500. When a patient in a wheelchair needs to perform facial recognition, they can pull the pull rod 500 by gripping the grip ball 510. A slider 520 for sliding up and down in the cavity 412 is fixedly installed at the upper end of the pull rod 500. A slider 521 for cooperating with the spiral groove 414 to control the rotation of the rotating rod 410 is fixedly installed on the outer wall of the slider 520. A limiting block 530 for limiting the pull rod 500 in cooperation with the limiting block 300 is fixedly installed at the upper end of the pull rod 500. A groove is opened at the lower end of the limiting block 300 for limiting the limiting block 530, so that when the patient pulls the pull rod 500 downward by gripping the grip ball 510... Limiting block 3 530 is limited by the lower end cavity of limiting block 2 300, so that the pulling rod 500 can only move up and down and cannot rotate. The pulling rod 500 drives the slider 1 520 to move downward and squeeze the reset spring 420. At the same time, it drives 421 to slide in the cavity of the spiral groove 414, which drives the rotating rod 2 410 to rotate, so that the spiral tooth 411 drives the worm gear 341 to rotate. The rotating rod 1 340, together with the support block 120, controls the door access body 100 to change its angle, so that the camera 110 can perform facial recognition on patients in wheelchairs.
