When the elevator door is opened and closed, the elevator floor door switch is driven, and the floor door body 3 slides along the support frame 1 and the guide slide groove 11. During the opening process of the elevator floor door, the gas spring 21 is compressed and contracted and rotates around the rotating shaft 2, which can reduce the shaking of the floor door body 3 when opening the floor door. When the floor door body 3 is opened, the telescopic motor 12 pushes the baffle 13 to extend to block the gap between the floor door body 3 and the elevator door, reducing the risk of children's feet being stuck in the gap when entering or leaving the elevator. When the floor door body 3 is closed, the telescopic motor 12 drives the baffle 13 to retract into the interior of the support frame 1 to avoid friction between the baffle 13 and the elevator door. The floor door body 3 and the support frame 1 are formed by the guide slide groove 11. The engaging sliding installation structure can guide and limit the floor door body 3 through the guide slide groove 11, so that the opening and closing of the floor door body 3 are more reliable and stable. The gas springs 21 are symmetrically arranged about the center line of the support frame 1. The four gas springs 21 are distributed on both sides of the support frame 1 in pairs. When the floor door body 3 is opened and closed, the gas springs 21 are extended and rotated with the movement of the floor door body 3, thereby making the opening and closing of the floor door body 3 more stable. The baffle 13 and the support frame 1 form a sliding installation structure through the telescopic motor 12. When the floor door body 3 is opened, the telescopic motor 12 pushes the baffle 13 to extend to block the gap between the floor door body 3 and the elevator door. When the floor door body 3 is closed, the telescopic motor 12 drives the baffle 13 to retract into the support frame 1 The interior of the baffle 13 is prevented from friction with the elevator door. The baffle 13 and the support frame 1 are arranged in parallel with each other. The parallel arrangement can make the baffle 13 move smoothly and reliably under the push of the telescopic motor 12. The telescopic motors 12 are evenly spaced on one side of the baffle 13. The evenly spaced telescopic motors 12 can push the baffle 13 to slide smoothly and quickly. The floor door body 3 and the support frame 1 are arranged in parallel with each other. The parallel arrangement can make the floor door body 3 more reliable and stable when opening and closing. The stainless steel skin 31 and the skeleton 32 are connected by rivets. The rivet connection can make the connection between the stainless steel skin 31 and the skeleton 32 more reliable and firm, thereby ensuring the structural strength of the floor door body 3.
[0036] The working principle of the utility model is as follows: when the device is used, the elevator door switch drives the elevator floor door switch, and the floor door body 3 slides along the support frame 1 and the guide slide groove 11. In the process of opening the elevator floor door, the gas spring 21 is compressed and shrinks and rotates around the rotating shaft 2, which can reduce the shaking of the floor door body 3 when opening the floor door. When closing the floor door body 3, the gas spring 21 is driven by the floor door body 3 to turn over and extend, so that the opening of the floor door body 3 is more stable, and when the two floor door bodies 3 are in contact, the buffer pad 4 can reduce the collision strength of the floor door body 3 when contacting, thereby increasing the floor door body The service life of the body 3 of the floor door is extended. When the floor door body 3 is opened, the telescopic motor 12 pushes the baffle 13 to extend to cover the gap between the floor door body 3 and the elevator door, reducing the risk of children's feet being stuck in the gap when entering or leaving the elevator. When the floor door body 3 is closed, the telescopic motor 12 drives the baffle 13 to retract into the interior of the support frame 1 to avoid friction between the baffle 13 and the elevator door. The floor door body 3 is composed of a stainless steel skin 31 and a frame 32 in combination with a foam plastic filling 33. The structural strength of the floor door body 3 can be increased by the frame 32 and the foam plastic filling 33.
