Detailed Description
In order to make the technical field personnel understand the utility model discloses the scheme, will combine the drawing in the embodiment of the utility model below, to the technical scheme in the embodiment of the utility model carries out clear, complete description.
As shown in fig. 1-4, in order to achieve the above purpose, the present invention adopts the following technical solutions: a portable face iris recognition device which is not easy to break comprises a portable iris recognition machine 1 and an anti-falling part arranged on the portable iris recognition machine 1; the anti-falling component comprises a balancing weight 2 fixedly arranged at the back of the portable iris recognition machine 1, a fixed block 3 fixedly arranged at the bottom of the portable iris recognition machine 1 and a sliding block 4 arranged on the end face of the fixed block 3 in a reciprocating manner.
The anti-falling component further comprises two trapezoidal blocks arranged on the fixed block 3, two trapezoidal grooves arranged on the end face, close to the portable iris recognition machine 1, of the sliding block 4, a rectangular block 50 fixedly arranged on the side face of the fixed block 3, a rectangular groove arranged on the side face of the rectangular block 50, a sliding block 51 arranged in the rectangular groove in a reciprocating manner, a supporting plate 52 fixedly arranged on the sliding block 51, an expansion spring 53 fixedly arranged at the bottom of the sliding block 51 and the rectangular groove, and two arc-shaped blocks 59 fixedly arranged on the side faces of the rectangular block 50, wherein the two trapezoidal blocks are positioned in the two trapezoidal grooves, and the two arc-shaped blocks 59 are respectively and symmetrically and fixedly arranged on the front side and the rear side of the side face of the rectangular block 50; when the device falls downwards, the head (namely one end for mounting the balancing weight 2) of the device is enabled to be downwards (namely towards the ground) under the action of the balancing weight 2, and the sliding block 4 slides downwards on the portable iris recognition machine 1 to cover the mirror surface by means of the matching of the two trapezoidal grooves and the two trapezoidal blocks, so that the damage of a convex block or other sharp objects on the ground to the mirror surface of a product can be avoided; when the device is contacted with the ground, the impact force is transmitted to the telescopic spring 53, the telescopic spring 53 is impacted to drive the sliding block 51 to be separated from the two arc-shaped blocks 59 (because the telescopic spring 53 is not provided with left, right, upper and lower limit positions, the sliding block 51 is easy to shake up and down under the impact effect, the telescopic spring 53 drives the sliding block 51 to shake down and then separate from the arc-shaped blocks 59), the separated sliding block 51 can push the abutting plate 52 to move to the lower part of the sliding block 4 to support the sliding block 4 (the sliding block 4 is kept in a state after sliding, so that the sliding block 4 is prevented from moving relative to the portable iris recognition machine 1 and the fixed block 3), the sliding block 4 is kept in a state of always covering the mirror surface, the device can be prevented from separating from the mirror surface under the vibration effect when colliding with the ground and exposing the mirror surface to the outside, and the mirror surface can be always protected in the falling process, the mirror surface of the product is prevented from being damaged.
The distance between each side surface of the slide block 51 and the side wall of the rectangular groove is 1 cm; therefore, the sliding block 51 can be separated from the two arc-shaped blocks 59, and the sliding block 4 can be supported by the supporting plate 52 to be incapable of being separated from the mirror surface when being reset by the impact of the ground, and only the mirror surface can be covered all the time, so that the safety and stability of the equipment are higher.
A first rubber shell is sleeved on the portable iris recognition machine, one end face and four side faces of the sliding block 4 are wrapped by a second rubber shell 999, and the balancing weight is located in the rubber shell; thereby avoiding other parts of the device from being smashed by the larger impact of the ground.
The portable iris recognition machine is in the prior art and is a schematic structure diagram, so the structure is not repeated.
