Detailed implementation manners

[0033] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described in some examples can also be combined in other examples.

[0034] In at least one embodiment of the present invention, a protection device for the door gap of an elevator car is disclosed. As Figures 1 - 15 shown, it includes a van - type main body 100. An open end 1500 of the van - type main body 100 is provided with a first box door 200. A first placement groove 300 is formed on the first box door 200. The first placement groove 300 is provided with an anti - pinch main board 400. A first buffer part for buffering the anti - pinch main board 400 is arranged in the first placement groove 300. The first buffer part includes a guiding part fixedly connected to the side of the anti - pinch main board 400. The guiding part is used to guide the moving direction of the anti - pinch main board 400. The anti - pinch main board 400 is connected to the first placement groove 300 through a first spring 500 for providing elastic force.

[0035] On the side of the anti-pinch main board 400, symmetrically arranged first clamping protrusions 600 are provided. The anti-pinch main board 400 is clamped in the first placement groove 300 through the first clamping protrusions 600, and a buffer rubber layer 700 is arranged in the first placement groove 300.

[0036] The upper end of the first box door 200 is connected to the van body 100 through an upper guide rail 800, and the lower end of the first box door 200 is connected to the van body 100 through a lower guide rail 900. A second box door 1000 is correspondingly arranged for the first box door 200. The second box door 1000 is connected to an external wall 1100. The upper end of the second box door 1000 is connected to the external wall 1100 through an upper guide rail 800, and the lower end of the second box door 1000 is connected to the external wall 1100 through a lower guide rail 900. A passage opening 1200 for passengers to pass through is opened on the external wall 1100. A first opening plate 1300 is arranged on the first box door 200, and a second opening plate 1400 is arranged on the second box door 1000.

[0037] When the above device is actually used, the first box door 200 drives the second box door 1000 to open through the first opening plate 1300. During the opening process of the first box door 200, if a finger is accidentally caught between the first box door 200 and the van body 100 and clamped, under the action of the first buffer part, there is a cooperation of a first spring 500 and a guiding part between the anti-pinch main board 400 and the first box door 200. The distance between the anti-pinch main board 400 and the first box door 200 becomes larger and buffers, and at this time, the clamped finger can be taken out.

[0038] Please refer to Figure 12 In an embodiment, the guiding part includes two symmetrically arranged first clamping grooves 501 opened in the first placement groove 300. First guiding rods 502 are fixedly connected in both of the two first clamping grooves 501. Two symmetrically arranged first guiding blocks 503 are fixedly connected to the side of the anti-pinch main board 400. The two first guiding blocks 503 are respectively sleeved on the outer sides of the first guiding rods 502. The first guiding blocks 503 are connected to the side wall of the first clamping groove 501 through a first spring 500 for providing elastic force. A connecting box body 505 is fixedly connected to the first box door 200, and a second buffer part for reducing buffering is arranged in the connecting box body 505.

[0039] The second buffer portion includes a second clamping groove 601 formed in the first placement groove 300. A first connection block 602 is clamped in the second clamping groove 601. The first connection block 602 is fixedly connected to the buffer rubber layer 700. A spacing adjustment portion for adjusting the spacing between the anti-pinch main board 400 and the first box door 200 is provided in the connection box body 505.

[0040] When the above-mentioned guiding portion is actually used, when the anti-pinch main board 400 moves, the first guiding block 503 moves along the direction of the first guiding 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 a stable connection state between the anti-pinch main board 400 and the first box door 200; after the anti-pinch main board 400 moves under the impact force of being pinched by a finger and moves to the buffer rubber layer 700, the impact force is buffered under the action of the buffer rubber layer 700 to avoid more serious injury to the pinched finger.

[0041] Please refer to Figure 8 、 Figure 11 、 Figure 13 、 Figure 14 and Figure 15 In an embodiment, if the finger is still pinched under the setting of the first buffer portion, at this time, it is necessary to further expand the spacing between the anti-pinch main board 400 and the van body 100. Therefore, in an embodiment, the spacing adjustment portion includes a second placement groove 701 formed in the first placement groove 300. A third clamping groove 702 communicating with the second clamping groove 601 is formed in the side surface of the second placement groove 701. A first adjustment plate 703 is provided in the third clamping groove 702. The first connection block 602 and the first adjustment plate 703 are connected through a connection portion. A second guiding block 704 is fixedly connected to the lower end of the first adjustment plate 703. A second guiding rod 705 is fixedly connected in the second placement groove 701. The second guiding block 704 is sleeved outside the second guiding rod 705. The second guiding block 704 is connected to the side wall of the second placement groove 701 through a second spring 706 for providing elastic force. A limiting portion for limiting is provided in the second placement groove 701.

[0042] The connection portion includes a first inclined surface 801 provided on the side surface of the first connection block 602. A second inclined surface 802 cooperating with the first inclined surface 801 is provided on the first adjustment plate 703. A fourth clamping groove 803 is provided on the first inclined surface 801. A second clamping protrusion 804 cooperating with the fourth clamping groove 803 is fixedly connected to the second inclined surface 802. Two anti-detachment protrusions 805 are symmetrically provided and fixedly connected to the side surface of the first connection block 602.

[0043] The limiting part includes a limiting main board 901. A pushing board 902 is fixedly connected to the side surface of the limiting main board 901. A through groove 903 cooperating with the pushing board 902 is formed on the first box door 200. A pulling part 904 is arranged on the pushing board 902. A third guiding 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 to both sides of the limiting main board 901. A first curved surface 907 is arranged on the limiting block 906. Two symmetrically arranged limiting rods 908 are fixedly connected to the first adjusting plate 703. A second curved surface 909 cooperating with the first curved surface 907 is arranged on the limiting rod 908. A magnetic block 910 magnetically connected to the limiting main board 901 is fixedly connected in the second placement groove 701.

[0044] When the above-mentioned spacing adjusting part is actually used and there is no need to adjust the spacing between the anti-pinch main board 400 and the van body 100, under the action of the first curved surface 907 and the second curved surface 909, the limiting rod 908 and the limiting block 906 ensure that the first adjusting 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 it is necessary to adjust the spacing between the anti-pinch main board 400 and the van body 100, press the pushing board 902 to drive the limiting main board 901 to move in the direction of the third guiding rod 905 and magnetically connect with the magnetic block 910, so that the first curved surface 907 is separated from the second curved surface 909. At this time, under the elastic force of the second spring 706, the second guiding block 704 moves in the direction of the second guiding rod 705, driving the first adjusting plate 703 to move. The movement of the first adjusting plate 703, under the cooperation of the second clamping protrusion 804 and the fourth clamping groove 803, drives the first connecting block 602 to move towards the first box door 200 under the action of the first inclined surface 801 and the second inclined surface 802, so that the spacing 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 finger without having to perform a demolition operation on the elevator. To restore the limiting rod 908 and the limiting block 906 to their original positions, just pull the pulling part 904.

[0045] Please refer to Figure 6 , a anti-falling part for preventing falling is arranged on the lower guide rail 900 connected to the second box door 1000.

[0046] The anti-falling part includes a plurality of first connecting rods 1001 fixedly connected to the lower guide rail 900 and distributed in an array. The ends of the plurality of first connecting rods 1001 are all rotatably connected to a brush 1003 through a first rotating shaft 1002.

[0047] The anti-falling part can prevent items from falling through the gap between the opening of the first box door 200 and the second box door 1000, and can scrape the first box door 200 in cooperation with the first rotating shaft 1002 and the brush 1003 to scrape off dust.

[0048] The embodiments of the present invention have been described above, but the embodiments are not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative rather than restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make more equivalent embodiments in various forms, all of which fall within the protection scope of this embodiment.
