The basic principles defined in the following description can be used in other implementation schemes, variation schemes, improvement schemes, equivalent schemes, and other technical schemes that do not deviate from the spirit and scope of the present utility model.

[0028] Those skilled in the art should understand that in the disclosure of the present utility model, the terms "longitudinal", "transverse", "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or position based on the orientation or position relationship shown in the drawings. It is only for the convenience of describing the present utility model in a simplified way, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on the present utility model.

[0029] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of one element can be one, while in other embodiments, the number of this element can be multiple. The term "one" should not be construed as a limitation on the number.

[0030] Please refer to Figures 1 - 5, Elevator electrical maintenance port support assembly, including: maintenance door 1, on which a telescopic staircase 2 is provided. The telescopic staircase 2 is a prior art and its working principle will not be described in detail here; a telescopic handrail 3 is connected to the telescopic staircase 2. The telescopic handrail 3 includes multiple telescopic rods 31 and connecting plates 32 fixed on the telescopic rods 31. The lower end of the connecting plate 32 is connected to the telescopic staircase 2. When the telescopic staircase 2 is pulled open, the telescopic handrail 3 is pulled open, facilitating maintenance personnel to go up the stairs.

[0031] Placement boxes 4, which are on the same side of the maintenance door 1 as the telescopic staircase 2. There are two placement boxes 4, and the two placement boxes 4 are symmetric about the telescopic staircase 2. The two placement boxes 4 can hold more tools. A rotating rod 11 is connected to the lower end of the maintenance door 1, and the placement box 4 is rotatably connected to the rotating rod 11. A support plate 5 installed on the maintenance door 1 is provided on the lower side of the placement box 4. The support plate 5 supports the opened placement box 4, which is beneficial to increasing the load-bearing capacity and stability of the placement box 4. An elastic locking rod 6 is connected to the placement box 4. A locking block 12 is fixed on the maintenance door 1, and a locking groove 13 into which the locking rod 6 is inserted is provided on the locking block 12. The placement box 4 is fixed to the maintenance door 1 through the locking rod 6 and the locking groove 13 to prevent it from opening.

[0032] The placement box 4 includes a bottom plate 41 and multiple side plates 42. The multiple side plates 42 are connected end to end to form an opening. The bottom plate 41 and the multiple side plates 42 form a placement groove 43. The opening of the opened placement box 4 faces upward. The support plate 5 contacts the bottom plate 41 of the opened placement box 4. Tools can be placed conveniently through the placement groove 43, reducing the need to repeatedly go back and forth to get tools during the climbing process and also preventing the instability caused by carrying tools on the stairs, especially when carrying some large tools.

[0033] Elastic members 7 are connected to the outer side surface of the placement box 4. There are two elastic members 7 on the same side. The elastic member 7 includes a fixed rod 71, which is fixed to the placement box 4. A sliding rod 72 slides on the fixed rod 71. A spring 73 is sleeved on the sliding rod 72 and the fixed rod 71. The two ends of the spring 73 are respectively connected to the sliding rod 72 and the side plate 42. The locking rod 6 is fixed to the sliding rod 72. A handle 8 is connected between the two sliding rods 72. In the storage state, the handle 8 is arranged close to the lower side of the placement box 4. The handle 8 being located on the lower side facilitates rotating the placement box 4.

[0034] During use, after the retractable staircase 2 is unfolded, the retractable handrail 3 follows to unfold. Then, pull the handle 8, and the sliding rod 72 slides on the fixed rod 71, causing the locking rod 6 to leave the locking groove 13. At this time, the spring 73 is stretched. After the locking rod 6 leaves the locking groove 13, rotate the placement box 4 so that the bottom plate 41 contacts the support plate 5. When there are many tools, the placement boxes 4 on both sides are opened simultaneously. After placing the maintenance tools, it is convenient for the maintenance personnel to bring the maintenance tools into the maintenance opening. After the maintenance is completed, first place the tools on the placement box 4, and then come down through the retractable staircase 2. After removing the maintenance tools, rotate the placement box 4 upward through the handle 8, and then pull the handle 8 so that when the placement box 4 contacts the inspection door 1, the locking rod 6 corresponds to the locking groove 13. Release the handle 8 so that the locking rod 6 is inserted into the locking groove 13, thereby fixing the placement box 4.

[0035] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. The object of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and described in the embodiments. Without departing from the said principles, the embodiments of the present invention can have any deformation or modification.
