Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments; all other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the first embodiment, as shown in fig. 1 to 4, the utility model includes an automatic opening and closing subway shield door, which includes a right fixed door 1, a right movable door 4 is slidably connected inside the right fixed door 1, a left movable door 2 is disposed on the left side of the right movable door 4, a left fixed door 3 is slidably connected on the left side of the left movable door 2, the right movable door 4 includes a door body 43, an elastic frame 42 is fixed on the left end of the door body 43, a positioning plate 45 is fixed inside the door body 43, a spring 44 and an expansion link 46 are fixed on the surface of the positioning plate 45, the expansion link 46 surrounds the surface of the spring 44, an extension plate 41 is fixed on the left end of the spring 44, the left movable door 2 includes a door panel 21, an elastic strip 22 is fixed on the right end of the door panel 21, and a pressing plate 23 is slidably connected on the right ends of the door panel 21 and the elastic strip 22.

When a vehicle arrives at a station, the driving device inside the left fixed door 3 and the right fixed door 1 drives the left movable door 2 and the right movable door 4 to move, then the left movable door 2 and the right movable door 4 move oppositely, the extrusion plate 23 on the surface of the left movable door 2 and the right movable door 4 is not extruded with the extrusion plate 41, the spring 44 returns to deform and ejects the extrusion plate 41 out, the telescopic rod 46 slides in the opening on the surface of the extrusion plate 41, when the left movable door 2 and the right movable door 4 are opened to a half, the extrusion plate 41 and the extrusion plate 23 are not extruded any more, after the opening and closing of the left movable door 2 and the right movable door 4 are completed, the extrusion plate 41 and the extrusion plate 23 occupy a certain space for getting off, when the left movable door 2 and the right movable door 4 are closed, the extrusion plate 41 and the extrusion plate 23 are extruded with each other, but the pressure is small, so as to remind passengers to stop getting on the vehicle, thereby ensuring the safety of the passengers.
