Description

Technical Field

[0001] The utility model relates to the technical field of subway equipment, in particular to a subway safety door pedal. Background Art

[0002] In order to ensure the safe running of subway cars, there is a gap between the subway track and the platform. This gap is the gap between the platform and the safety door after the subway arrives at the station. Due to the existence of the gap, passengers need to cross the gap when getting on and off the subway, which is not safe enough. By installing a safety door pedal to connect the platform and the safety door pedal, passengers can step on the pedal when getting on and off the subway, reducing the incidence of safety accidents;

[0003] In this regard, the Chinese utility model patent with authorization announcement number CN206644805U discloses a subway safety door pedal structure, including: a door machine, a door panel, a pedal and an actuating mechanism, the actuating mechanism includes a connecting rod, an articulated seat and a rack-and-pinion mechanism, the connecting rod is divided into a first connecting rod and a second connecting rod, the first connecting rod and the second connecting rod are parallel to each other, the articulated seat includes a first articulated seat and a second articulated seat, the first articulated seat is fixedly mounted on the platform floor, the first articulated seat is fixed to the bottom of the pedal, the rack-and-pinion machine includes a gear rotatably mounted on one group of the first articulated seats and a rack fixedly mounted on the bottom of the door panel and meshing with the gear, the first connecting rod and the gear are welded and fixed at the center of the circle. The utility model provides a pedal, and the opening and closing of the pedal is controlled by the cooperation of the connecting rod mechanism and the rack-and-pinion mechanism, which can prevent passengers from stepping on empty space and losing items when getting on and off the train;

[0004] Existing safety door pedals are often provided with anti-slip grooves for safety. However, after being stepped on for a long time, the anti-slip grooves are easily worn out, and the safety is reduced. The safety door pedal needs to be replaced as a whole, which increases the cost. In addition, the safety door pedal lacks shock absorption function. After the pedal body is stepped on, the impact force acts directly on the safety door, increasing the probability of deformation of the safety door. For this reason, we propose a subway safety door pedal to solve the above problems. Utility Model Content
