When the invention is used, a pedestrian passes through the door frame 1 and inevitably passes through the pedal 13, when the pedestrian steps on the top side of the pedal 13, the pedal 13 moves downwards, the second spring rod 14 is compressed to the shortest, the pedal 13 drives the fixed rod of the first spring rod 11 to rapidly descend, the first spring rod 11 is stretched and forms large elastic potential energy, the upper end of the first spring rod 11 forms downward pulling force on the bar-shaped teeth 10, the bar-shaped teeth 10 move downwards, the bar-shaped teeth 10 drive the third gear 7 to rotate, the third gear 7 drives the second bevel gear 9 to rotate through the first gear 8, the second bevel gear 9 drives the first gear 5 to rotate through the connecting rod, the first gear 5 drives the vertical shaft 2 to rotate through the second gear 6, the vertical shaft 2 drives the door body 3 to rotate, the door body 3 is rapidly opened, the door body 3 drives the fourth gear 20 to rotate along the axis of the vertical shaft 2 through the rotating shaft 19, the fourth gear 20 rolls along the right side tooth of the special-shaped gear 16 to rotate, the safety belt of the safety belt retractor 21 wound on the upper end of the periphery of the rotating shaft 9 is continuously torn down, until the fourth gear 20 is separated from the right side tooth of the special-shaped gear 16 and is opened along with the continuation of the door body 3, the fourth gear 20 is positioned between the right side tooth and the front side tooth of the special-shaped gear 16, the fourth gear 20 is separated from the special-shaped gear 16, the safety belt of the safety belt retractor 21 is completely torn down from the periphery of the rotating shaft 19 under the action of the pulling force of the safety belt retractor 21 on the safety belt, until the fourth gear 20 is meshed with the front side tooth of the special-shaped gear 16 to be matched with the rotation of the rotating shaft 19, the pulling-out end of the safety belt retractor 21 is continuously wound on the periphery of the rotating shaft 19, because the rotating speed of the door body 3 is too fast, the rotation speed of the rotating, the safety belt retractor 21 causes the safety belt to be blocked, the safety belt cannot be continuously pulled out from the safety belt retractor 21, so that the rotating shaft 19 cannot continuously rotate, the fourth gear 20 is blocked with the front side teeth of the special-shaped gear 16, the door body 3 cannot be continuously opened, the door body 3 is in a half-open state and moves downwards along with the bar-shaped teeth 10, the door body 3 is quickly opened to the half-open state, the elastic potential energy generated by the first spring rod 11 is released, the elastic potential energy of the first spring rod 11 is small at the moment, a pedestrian applies small acting force to the door body 3 to reversely rotate the door body 3 in the closing direction, the fourth gear 20 reversely rotates along the front side teeth of the special-shaped gear 16, the pulling end of the safety belt retractor 21 is separated from the periphery of the rotating shaft 19, the pulling force of the rotating shaft 19 and the pulling end of the safety belt retractor 21 is withdrawn, and the self-locking of the, then the door body 3 is loosened, the first spring rod 11 continues to release elastic potential energy, the bar-shaped teeth 10 are pulled downwards, at the moment, because the elastic potential energy of the first spring rod 11 is small, the door body 3 slowly rotates to be opened, the four gears 20 are meshed and matched with the front side teeth of the special-shaped gear 16, the rotating shaft 19 continues to rotate, the pulling-out end of the safety belt retractor 21 is continuously wound on the periphery of the rotating shaft 19, the door body 3 is slowly opened to a completely opened state, so that severe collision between the right front side edge of the door body 3 and a wall body is avoided, meanwhile, hands of a pedestrian are prevented from being pinched, when the door body 3 is completely opened and semi-opened, the pedestrian is kept to pass through the pedal 13 uninterruptedly, at least one pedestrian on the pedal 13 is prevented from ascending and resetting, the door body 3 can be kept in a completely opened and semi-; after the pedestrian passes through door frame 1 and gets off from step 13, step 13 resets under the elastic thrust effect of second spring beam 14, step 13 drives the dead lever rebound of first spring beam 11, the upper end of first spring beam 11 drives bar tooth 10 rebound, the above-mentioned process is backward gone on, door body 3 can resume half closed state fast, avoid door body 3 and door frame 1 violent striking to produce abnormal sound, destroy, avoid pressing from both sides wounded pedestrian's hand, stimulate door body 3 forward again, make door body 3 open the angle increase, to removing the locking of safety belt retractor 21 to the safety belt, door body 3 resumes to the complete closure state under the elastic potential energy effect of first spring beam 11.
Specifically, as shown in the figure, the lower side of the front side of the door frame 1 according to the present embodiment is provided with a plurality of strip-shaped through grooves 22, the strip-shaped through grooves 22 are respectively provided with a connecting rod 23, and the pedal 13 on the front side and the pedal 13 on the rear side are fixedly connected through the connecting rod 23. When the pedal 13 on one side is stepped on, the pedal 13 on the other side is driven by the connecting rod 23 to move downwards, and the connecting rod 23 moves downwards along the corresponding strip-shaped through groove 22.
Specifically, as shown in the drawing, the distance between the front and rear width of the pedal 13 at the front side of the present embodiment is twice the distance between the left and right width of the door body 3, and when a person stands at the front end of the top side of the pedal 13 at the front side, the door body 3 is rotated to open and not contact with the person. The door body 3 is prevented from being opened to contact with a human body when a pedestrian passes through the front end of the top side of the pedal 13 at the front side of the station, and the pedestrian is prevented from being hit by the door body 3.
Further, as shown in the figure, a stopper 24 is fixedly installed at the upper right corner of the inner side of the door frame 1, and the front side of the stopper 24 is in contact fit with the rear side of the door body 3. The front side of the stopper 24 contacts and cooperates with the rear side of the door body 3, and the door body 3 is in a closed state while preventing the door from being opened backward.
Further, as shown in the drawings, a door handle 25 is fixedly mounted on the right side of the front side of the door body 3 according to the embodiment. The door body 3 is pulled forwards through the pulling of the door handle 25, so that the hands are prevented from being placed on the edge of the door body 3, and the probability that the hands are squeezed is reduced.
Further, as shown in the figure, the up-down displacement of the pedal 13 according to the present embodiment is 5 mm when being depressed. The up-down displacement of the pedal 13 is small, and the influence on the walking of the pedestrian is negligible.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
