Description

Technical Field

[0001] The utility model belongs to the technical field of turnstiles, and particularly relates to an adjustable face recognition turnstile. Background Art

[0002] A face recognition turnstile consists of two parts: a face recognition turnstile head and a turnstile. The difference between a face recognition turnstile and a separately used turnstile is that in addition to swiping cards and two-dimensional codes to open the gate, it can also perform face recognition (face swiping) to open the gate, which not only improves the entry and exit experience but also enhances the security level.

[0003] However, the existing intelligent face recognition turnstiles do not have an adjustment function. Since everyone has a different height, when recognizing people who are too tall or too short, the face recognition may not be comprehensive, resulting in the electric gate being unable to open. Especially for children or people in wheelchairs, due to the excessive height of the turnstile platform, they usually need to use the manual passage, and the efficiency of passing through the turnstile is slow and troublesome.

[0004] Therefore, it is necessary to provide a new adjustable face recognition turnstile to solve the above technical problems. Content of the Utility Model

[0013] Compared with the related art, the adjustable face recognition gate provided by the utility model has the following beneficial effects:

[0014] The utility model provides an adjustable face recognition gate:

[0015] 1. By introducing a lifting motor and a screw structure, the facial recognition device can be adjusted up and down according to the height of different groups of people, thereby achieving comprehensive facial recognition of people of different heights, effectively solving the problem of incomplete recognition caused by the fixed height of traditional gates. It not only supports conventional card swiping and QR code gate opening methods, but also adds a facial recognition function, making entry and exit more convenient and efficient. The adjustable design allows all groups to use it comfortably, especially for children, people in wheelchairs and other groups with short stature or physical disabilities, greatly improving their travel experience;

[0016] 2. By adding the face recognition function, the security of the gate is further improved, so that only certified personnel can pass through, effectively preventing illegal intrusion. The setting of the middle section recognition mechanism, through the cooperation of the movable rod and the drive mechanism, realizes the flexible adjustment of the recognition camera at different heights and angles, so that it is suitable for more complex usage scenarios. At the same time, the combination of the fixed gear and the rotating motor allows the angle of the recognition camera to be fine-tuned, further expanding the scanning and recognition range;

[0017] 3. The design of the installation cavity makes reasonable use of the internal space of the gate body, which not only ensures the installation and operation of the equipment, but also reduces the occupation of the external space. Through reasonable layout and compact design, the overall structure is more compact and beautiful. By adding structures such as the bottom plate and guide rods, the stability of the identification device is enhanced to prevent angle deviation or shaking during the lifting process. At the same time, the use of high-quality materials and processes makes the entire equipment more durable and reliable. BRIEF DESCRIPTION OF THE DRAWINGS
