[0021] The upper end of the first door 200 is connected to the box-type body 100 through an upper guide rail 800, and the lower end of the first door 200 is connected to the box-type body 100 through a lower guide rail 900. A second door 1000 is provided corresponding to the first door 200, and the second door 1000 is connected to an external wall 1100. The upper end of the second door 1000 is connected to the external wall 1100 through an upper guide rail 800, and the lower end of the second door 1000 is connected to the external wall 1100 through a lower guide rail 900.

[0022] When the above-mentioned device is actually used, the first door 200 drives the second door 1000 to open through the first door opening plate 1300. During the opening of the first door 200, if a finger is accidentally brought into the space between the first door 200 and the box body 100 and is clamped, under the action of the first buffer part, the first spring 500 and the guide part cooperate between the anti-pinch main board 400 and the first door 200, and the distance between the anti-pinch main board 400 and the first door 200 becomes larger and buffered, so that the clamped finger can be taken out.

[0023] See also Fig.12 In one embodiment, the guide portion includes two first clamping grooves 501 symmetrically arranged in the first placement groove 300, and the two first clamping grooves 501 are fixedly connected with a first guide rod 502.

[0025] When the above-mentioned guide part is actually used, when the anti-pinch main board 400 moves, the first guide block 503 moves along the direction of the first guide rod 502, so that the first spring 500 is compressed. It should be noted that the elastic force of the first spring 500 is relatively large, which can ensure that the anti-pinch main board 400 and the first box door 200 are in a stable connection state; after the anti-pinch main board 400 moves due to the impact force of being pinched by the fingers, after moving to the buffer rubber layer 700, the impact force is buffered under the action of the buffer rubber layer 700 to avoid more serious injuries to the pinched fingers.

[0026] See also Figure 8 , Fig.11 , Fig.13 , Fig.14 and Fig.15In one embodiment, if the finger is still clamped under the setting of the first buffer portion, it is necessary to further expand the distance between the anti-pinch main board 400 and the box-type main body 100. Therefore, in one embodiment, the distance adjustment portion includes a second placement groove 701 opened in the first placement groove 300, and the side of the second placement groove 701 is provided with a third clamping groove 702 connected to the second clamping groove 601, and a first adjustment plate 703 is arranged in the third clamping groove 702. The first connecting block 602 and the first adjustment plate 703 are connected through a connecting portion, and a second guide block 704 is fixedly connected to the lower end of the first adjustment plate 703. A second guide rod 705 is fixedly connected in the second placement groove 701, and the second guide block 704 is sleeved on the outside of the second guide rod 705. The second guide block 704 is connected to the side wall of the second placement groove 701 through a second spring 706 for providing elastic force, and a limiting portion for limiting is arranged in the second placement groove 701.

[0028] The limiting part includes a limiting main board 901, a push plate 902 is fixedly connected to the side of the limiting main board 901, a through groove 903 cooperating with the push plate 902 is opened on the first box door 200, a pulling part 904 is arranged on the push plate 902, a third guide rod 905 passing through the limiting main board 901 is fixedly connected in the second placement groove 701, symmetrically arranged limiting blocks 906 are fixedly connected on both sides of the limiting main board 901, a first curved surface 907 is arranged on the limiting blocks 906, two symmetrically arranged limiting rods 908 are fixedly connected to the first adjustment plate 703, a second curved surface 909 cooperating with the first curved surface 907 is arranged on the limiting rod 908, and a magnetic block 910 magnetically connected to the limiting main board 901 is fixedly connected in the second placement groove 701.

[0029] When the above-mentioned spacing adjustment part is actually used, when there is no need to adjust the spacing between the anti-pinch main board 400 and the box-type main body 100, under the action of the first curved surface 907 and the second curved surface 909, the limit rod 908 and the limit block 906 ensure that the first adjustment plate 703 and the first connecting block 602 are in a balanced state. At this time, the first connecting block 602 cannot move, and only the position of the anti-pinch main board 400 is limited. If a finger is pinched and the spacing between the anti-pinch main board 400 and the box-type main body 100 needs to be adjusted, the push plate 902 is pressed down to drive the limit main board 901 to move in the direction of the third guide rod 905 and magnetically connect with the magnetic block 910, so that the first curved surface 907 Disengage from the second curved surface 909. At this time, under the elastic force of the second spring 706, the second guide block 704 moves in the direction of the second guide rod 705, driving the first adjustment plate 703 to move. The first adjustment plate 703 moves in cooperation with the second clamping protrusion 804 and the fourth clamping groove 803, driving the first connecting block 602 to move toward the first box door 200 under the action of the first inclined surface 801 and the second inclined surface 802, so that the distance between the first connecting block 602 and the anti-pinch main board 400 becomes larger. At this time, there is enough space to take out the pinched fingers without having to perform dismantling operations on the elevator. It is only necessary to restore the limit rod 908 and the limit block 906 to their original positions and pull the pulling part 904.
