[0027] Please refer to Figure 3, there are two sets of limiting rings 45 symmetrically arranged on the outer side of the support rotating shaft 43. The installation flap 47 is arranged between the two sets of limiting rings 45. The bottom of the inner cavity of the base 1 is fixedly connected with a support seat 14 for the two support rotating shafts 43 to be rotatably connected. A through hole 15 for the two support rotating shafts 43 to be rotatably connected is opened on the upper surface of the base 1. The two support rotating shafts 43 can be individually angle - flipped through the two electric push rods 42, so as to facilitate the one - way passage of pedestrians.

The adhered side of the reflective warning strip 54 is in the reverse direction to warn pedestrians to avoid going against the traffic flow.

[0033] Please refer to Figure 1 , a face recognition device 3 is installed on the upper surface of the positioning frame 2, and a controller 13 electrically connected to the face recognition device 3 is arranged at the bottom of the inner cavity of the base 1. The controller 13 is respectively electrically connected to two groups of electric push rods 42. The controller 13 receives the signal of the face recognition device 3, so as to control the corresponding electric push rod 42 to start, so as to open and close the access guardrail 5 and improve the passing efficiency of pedestrians.

[0034] Please refer to Figures 1 to 2 , a plurality of groups of heat dissipation holes 9 are formed in the upper ends of both sides of the base 1, and dust-proof nets 12 covering the heat dissipation holes 9 are arranged on the opposite sides of the inner cavity of the base 1. The heat generated by the controller 13 and the electric push rod 42 can be dissipated through the heat dissipation holes 9, improving the heat dissipation effect, and the dust-proof net 12 can prevent dust from entering and avoid the influence of dust on the operation of the electric push rod 42.

[0035] Please refer to Figures 1 to 2 , side plates 10 are fixedly connected to the lower ends of the other two sides of the base 1. Ground plug bolts 11 are inserted into the upper surfaces of the two groups of side plates 10. The upper surface of the base 1 is rotatably connected with a maintenance cover 6. A convex plate 7 is fixedly connected to one side of the maintenance cover 6. A fixing bolt 8 bolted to the base 1 is inserted into one side of the convex plate 7. The convex plate 7 can be fixed by the fixing bolt 8, so as to facilitate the opening and closing of the maintenance cover 6, facilitate the maintenance of the opening and closing mechanism 4 and the controller 13, and improve the maintenance efficiency.

[0036] During use, pedestrians are identified by the face recognition device 3, and then the signal is transmitted to the controller 13 after recognition. After the controller 13 recognizes, it controls the telescopic end of the corresponding electric push rod 42 to extend, so that the support rotating shaft 43 rotates by 90°, and then drives the installation flap 47 to rotate by 90°. While the installation flap 47 rotates, it drives the corresponding access guardrail 5 to rotate, so as to open the access guardrail 5 and facilitate pedestrians to pass. And when pedestrians walk towards each other, the two groups of electric push rods 42 synchronously drive the connecting rod 46 to rotate around the support rotating shaft 43, so that the two groups of access guardrails 5 rotate in the same direction, so as to facilitate pedestrians to enter and exit, improve the entry and exit efficiency, and the rotation direction of the access guardrail 5 is consistent with the walking direction during entry and exit, avoiding pinching pedestrians when the access is opened and closed, improving the practicability, and a reflective warning strip 54 is arranged on the access guardrail 5. One side of the reflective warning strip 54 on the access guardrail 5 is the side where passage is prohibited, avoiding pedestrians passing in the reverse direction.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
