[0025] The technical solution of the utility model is described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figures 1 to 5 As shown, the iris collection auxiliary support structure of a portable biometric collection device described in the utility model includes a base 11, a support rod 12, a movable part 13 and a mounting plate 14; the base 11 is fixedly connected to the first end of the support rod 12, the movable part 13 is installed at the second end of the support rod 12 with an adjustable height position, and a locking component 1 is provided between the movable part 13 and the support rod 12; the mounting plate 14 is installed at one side of the movable part 13 with an adjustable angle position, and a locking component 2 is provided between the mounting plate 14 and the movable part 13; a back plate 41 is fixed to the first side of the mounting plate 14, and a positioning groove 42 for positioning the collection device is provided on the back plate 41, and a binocular contour part 21 is fixed to the second side of the mounting plate 14 through a distance control rod assembly. With this arrangement, the bracket structure is mainly used in conjunction with a portable biometric acquisition device with a flat structure. When in use, the acquisition device is positioned on the positioning groove 42 on the back plate 41. The user fits the binocular contour piece 21 and stares at the iris window lens of the acquisition device with eyes wide open. There is no need to hold the acquisition device, thereby ensuring the stability of the acquired image and enabling the acquisition of high-quality images.

[0027] It should be noted that the angular position of the mounting plate 14 relative to the movable part 13 can be adjusted according to actual needs, thereby adjusting the angular position of the collection device. At the same time, the height position of the movable part 13 relative to the support rod 12 can be adjusted according to actual needs, thereby adjusting the height position of the collection device, which is more convenient to use.

[0028] In actual application, the base 11 is vertically fixedly connected to the first end of the support rod 12 .

[0029] In this embodiment, the movable member 13 is a sleeve, and the locking component 1 is a clamp 61 or a bolt. The clamp 61 or the bolt locks the movable member 13 on the support rod 12. When adjusting the height position of the movable member 13, the clamp 61 or the bolt is loosened, and the movable member 13 is slid up and down along the support rod 12. After adjusting the height position of the movable member 13, the clamp or the bolt is locked; more specifically, when the locking component 1 is the clamp 61, as Figure 4 As shown, two clamps 61 are located at the upper and lower ends of the movable part 13, and the movable part 13 is positioned by locking the support rod 12; when the locking component is a bolt, the bolt passes through the movable part 13 (the movable part 13 is provided with a screw hole that matches the bolt) and then abuts against the support rod 12 and is locked, thereby positioning the movable part 13.

[0030] It should be noted that, compared with the height adjustment structure of the prior art, the structure of the utility model is simpler, the cost is lower, and the adjustment is more convenient.

The two rotating members 71 are correspondingly hinged, and the two rotating members 71 are locked by the bolts. When the angle position of the mounting plate 14 is adjusted, the bolts are unscrewed, and the two rotating members 71 are hinged by a rotating shaft, such as Figure 4 As shown, the mounting plate 14 can rotate up and down relative to the movable member 13. After adjusting the angle of the mounting plate 14, the bolts are screwed on to lock the two rotating members 71. The structure is simple, the cost is low, and the adjustment is convenient.

[0032] In this embodiment, the first end of the distance control rod assembly is fixed to the mounting plate 14 by a fastening screw 51, and a limit platform 43 corresponding to the distance control rod assembly is provided on the mounting plate 14, and the second end of the distance control rod assembly is fixed to the binocular contour member 21 by a fastening screw 51. In this way, the fixing method of the fastening screw 51 makes it easy to load and unload.

[0033] It should be noted that a limiting platform 43 is provided on the mounting plate 14, and the limiting platform 43 can be used for guiding when the distance control rod assembly is installed, and the distance control rod assembly is limited in a horizontal position after being fixed.

[0034] In this embodiment, the first end and the second end of the distance control rod assembly are both provided with waist-shaped holes 33 corresponding to the fastening screws 51, and the binocular contour member 21 and the mounting plate 14 are both provided with adjustment slots 22 corresponding to the fastening screws 51. In this way, the fastening screws 51 have a larger assembly space, and the fastening position of the fastening screws 51 can be finely adjusted.

[0035] In this embodiment, the distance control rod assembly includes a distance control rod 1 31 and a distance control rod 2 32. This arrangement makes the fixing between the binocular contour member 21 and the mounting plate 14 better, thereby ensuring the stability and reliability between the binocular contour member 21 and the mounting plate 14.

[0036] In this embodiment, the acquisition device is detachably mounted in the positioning groove 42, and a soft rubber pad 44 corresponding to the acquisition device is provided in the positioning groove 42; and a soft rubber pad 44 corresponding to the acquisition device is provided on the back plate 41. This arrangement makes it more convenient to use, and the soft rubber pad 44 can prevent the acquisition device from being damaged.

[0037] In this embodiment, the base 11 is a tempered glass base; the support rod 12 is a stainless steel support rod; the binocular contour part 21 is a plastic contour part; the fastening screw 51 is a metal hand-tightening fastening screw; the mounting plate 14 is a metal VESA standard hole back plate; the back plate 41 is an aluminum alloy back plate; the distance control rod is an aluminum alloy distance control rod; and the soft rubber pad 44 is a TPU soft rubber pad.
