DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figures 1 to 3The utility model provides a technical solution: a traffic anti-stepping telescopic device, including a platform 1, a support frame 2 is installed on one side of the platform 1, and a first bracket 3 and a second bracket 12 are respectively arranged on the corresponding two sides of the support frame 2, a pedal body 4 is rotatably connected between the first bracket 3 and the second bracket 12, and an electric telescopic rod 5 is rotatably connected to the bottom of the first bracket 3 and the second bracket 12 on one side of the support frame 2, and the output end of the electric telescopic rod 5 is rotatably connected to a threaded column 6, and the threaded column 6 is threadedly connected to the bottom of the pedal body 4. The threaded column 6 is rotatably connected to the output end of the electric telescopic rod 5, so that the electric telescopic rod 5 can push the pedal body 4 to rotate when it is running, and extend from one side of the platform 1. When the pedal body 4 is turned over to be flush with the platform 1, there is still a small gap between the pedal body 4 and the tram, which is beneficial to increase the safety of the device. The pedal body 4 includes a support plate 41 and a bottom plate 42. Two first springs 43 are fixedly connected between the support plate 41 and the bottom plate 42. A damper 44 is installed between the support plate 41 and the bottom plate 42 and on one side of the two first springs 43. In cooperation with the first spring 43, the support plate 41 can be subjected to shock absorption and buffering of the pedal pressure, which is beneficial to increase the service life of the pedal body 4. A threaded hole 45 cooperating with the threaded column 6 is provided inside the bottom plate 42, so that the tram can be easily stepped on. The movable telescopic rod 5 can be removed from the pedal body 4 through the threaded column 6. A flashlight 7 is installed on the outer wall of the support frame 2 and on one side of the second bracket 12. An emergency circuit is used to remind and illuminate the gap between the tram and the platform 1 when a power outage occurs to avoid accidents. The hidden structure will not hinder the movement of pedestrians and luggage. A rotating shaft 9 is installed on both sides corresponding to the baffle 8. A slide groove 10 is provided inside the support frame 2. A slider 11 is slidably connected inside the slide groove 10. The slider 11 is fixedly connected to the second bracket 12. A second spring 13 is installed inside the slide groove 10. The second spring 13 is fixedly connected to the slider 11. The second bracket 12 and the first bracket 3 are both provided with a The slot 14 in which the rotating shaft 9 is plugged is connected to the second bracket 12 and the slider 11, so that the second bracket 12 can be pulled away from the first bracket 3, so that the rotating shaft 9 on both sides of the pedal body 4 can be disengaged from the slot 14 in the first bracket 3 and the second bracket 12, and the pedal body 4 can be disassembled. It can also be reset under the action of the second spring 13, and the baffle 8 can be quickly plugged in to facilitate the installation of the pedal body 4. Baffles 8 are installed on both sides corresponding to the top of the pedal body 4, which is beneficial to prevent objects dropped on the pedal from rolling into the gap between the tram and the platform 1. An anti-slip pad 15 is installed on the top of the pedal body 4 to increase friction with the sole, further preventing pedestrians from slipping.

[0022] In summary, the traffic anti-stepping telescopic device, when in use, the support frame 2 and the pedal body 4 are installed at the parking point on one side of the platform 1. When the tram arrives at the station, the electric telescopic rod 5 runs, and by extending, it pushes the pedal body 4 to rotate so that it is flush with the platform 1, filling the gap between the tram and the platform 1. At this time, pedestrians can step over the pedal body 4 and walk out of the tram. When the tram is running, the electric telescopic rod 5 drives the pedal body 4 to reset. When a power outage occurs, the flashing light 7 on one side of the support frame 2 automatically runs to warn and illuminate the space in front of the platform 1. Since the support frame 2 uses the first bracket 3 and the second bracket 12 on both sides to The plate body 4 is clamped. When the pedal body 4 needs to be replaced, the second bracket 12 is connected to the slider 11 in the support frame 2. Under the action of the second spring 13 on one side of the slider 11, the second bracket 12 can be directly slid to increase the distance between it and the first bracket 3, so that the slots 14 on one side of the first bracket 3 and the second bracket 12 leave the rotating shafts 9 on both sides of the pedal body 4. After the pedal body 4 is separated from the first bracket 3 and the second bracket 12, the threaded column 6 at the output end of the electric telescopic rod 5 is rotated to disengage it from the bottom of the pedal body 4, and the pedal body 4 can be removed. Similarly, when installing, the reverse operation can be performed.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
