[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0030] It should be noted that, in the description of the present invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] Figure 1-Figure 2 The utility model provides a subway power supply device that is easy to maintain, including a power supply box 1, one side of which is open and has a cabinet door 2 hingedly connected, and the power supply box 1 is provided with:

[0032] Limiting mechanism;

[0033] An illumination lamp 3, which is connected to the limiting mechanism via a gooseneck tube 4, wherein the gooseneck tube 4 can slide up and down relative to the limiting mechanism and be connected and fixed to the limiting mechanism at any position of its sliding track;

[0034] A contact switch 5, wherein the cabinet door 2 contacts the contact switch 5 when the cabinet door 2 is closed, and does not contact the contact switch 5 when the cabinet door 2 is opened;

[0035] Light sensor;

[0036] A controller is electrically connected to the lighting lamp 3, the contact switch 5 and the light sensor respectively.

[0037] In this embodiment, the light intensity in the power supply box 1 after the cabinet door 2 is opened is obtained by the light sensor, and the light intensity threshold is set in the controller in advance. When the light intensity in the power supply box 1 is greater than the light intensity threshold, the lighting conditions in the subway can meet the maintenance needs, and the lighting lamp 3 does not need to work. When the light intensity in the power supply box 1 is less than the light intensity threshold, the lighting conditions in the subway cannot meet the maintenance needs. At this time, the controller controls the lighting lamp 3 to start working. When the staff does not detect, after the cabinet door 2 is closed, there is no light source in the power supply box 1. At this time, the light intensity in the power supply box 1 is definitely less than the light intensity threshold. In order to avoid the lighting lamp 3 being always in the working state after the cabinet door 2 is closed, the contact switch 5 is connected to the power supply circuit of the lighting lamp 3. When the cabinet door 2 is closed, it conflicts with the contact of the contact switch 5. At this time, the power supply circuit of the lighting lamp 3 is disconnected, and the lighting lamp 3 does not work. When the cabinet door 2 is opened, the contact with the contact switch 5 is released, and the power supply circuit of the lighting lamp 3 is closed, and the lighting lamp 3 works. In this embodiment, the gooseneck tube 4 is slid up and down to adjust its height to the desired position, and then the gooseneck tube 4 is connected and fixed to the limiting mechanism, and then the horizontal position of the lighting lamp 3 and its lighting direction are adjusted. At the same time, the height of the lighting lamp 3 can also be fine-tuned through the gooseneck tube 4, so that the lighting lamp 3 can meet the needs of the staff.

[0038] Preferably, as another embodiment of the present utility model, the limiting mechanism includes:

[0039] A first slide rail 6, which is vertically arranged on the inner wall of the power supply box 1;

[0040] A first sliding block 7 is provided with a first sliding groove corresponding to the first sliding rail 6, and is slidably arranged on the first sliding rail 6 through the first sliding groove, and a plurality of first threaded through holes are provided on the inner wall of the first sliding groove, and first positioning bolts 8 are installed in the inner threads of the threaded through holes, and the first sliding block 7 can be connected and fixed to the first sliding rail 6 by tightening the first positioning bolts 8;

[0041] The positioning block 9 is connected to the gooseneck tube 4. The first sliding block 7 is provided with a first positioning groove matching the positioning block 9. The first sliding block 7 is detachably embedded in the first positioning groove.

[0042] In this embodiment, the positioning block 9 is inserted into the first positioning groove. The positioning block 9 is embedded in the first positioning groove and connected and fixed with the first slider 7. The connection between the gooseneck tube 4 and the first slider 7 can be achieved. Then the first positioning bolt 8 is loosened, and the first slider 7 is slid up and down on the first slide rail 6 to adjust its position. Finally, the first positioning bolt 8 is tightened to connect and fix the first slider 7 to the first slide rail 6.

[0043] Preferably, as another embodiment of the present utility model, Figure 3 As shown, the limiting mechanism also includes:

[0044] A second slide rail 10, which is vertically arranged on the inner wall of the power supply box 1 and is arranged opposite to the first slide rail 6;

[0045] A second slider 11 is provided with a second slide groove corresponding to the second slide rail 10, and is slidably arranged on the second slide rail 10 through the second slide groove, and a plurality of second threaded through holes are provided on the inner wall of the second slide groove, and second positioning bolts 12 are installed in the inner threads of the threaded through holes, and the second slider 11 can be connected and fixed to the second slide rail 10 by tightening the second positioning bolts 12;

[0046] The second sliding block 11 is provided with a second positioning groove matched with the positioning block 9 , and the second sliding block 11 is detachably embedded in the second positioning groove.

[0047] In this embodiment, if the width of the power supply box 1 is large, the length of the gooseneck tube 4 needs to be extended accordingly. Then, under the gravity of the illuminating lamp 3, the gooseneck tube 4 is easily bent, resulting in poor stability and failure to provide a good and stable positioning for the illuminating lamp 3. Therefore, in this embodiment, a second slide rail 10 is provided opposite to the first slide rail 6, and the positioning block 9 on the gooseneck tube 4 is selectively embedded in the first positioning groove or the second positioning groove, so that the length of the gooseneck tube 4 can be shortened while meeting the need to adjust the position of the illuminating lamp 3.

[0048] Preferably, as another embodiment of the present invention, both upper and lower ends of the first slide rail 6 and the second slide rail 10 are provided with limit blocks 13 .

[0049] In this embodiment, the sliding trajectories of the first slide block 7 and the second slide block 11 are limited by the limit blocks 13 at the upper and lower ends of the first slide rail 6 and the second slide rail 10 to prevent them from falling off from both ends of the first slide rail 6 and the second slide rail 10.

[0050] Preferably, as another embodiment of the present utility model, a slot 14 for fixing the gooseneck 4 is provided on the cabinet door 2 .

[0051] In this embodiment, after maintenance, the height of the gooseneck tube 4 is adjusted first, and then the gooseneck tube 4 is rotated until it is stuck in the slot 14, so that the gooseneck tube 4 can be fixed on the cabinet door 2, and the gooseneck tube 4 and the lighting lamp 3 can be fixed when not under maintenance.

[0052] Preferably, as another embodiment of the present invention, a resisting member 15 corresponding to the contact point of the contact switch 5 is provided on the cabinet door 2 .

[0053] In this embodiment, after the cabinet door 2 is closed, the resisting member 15 contacts the contact point of the contact switch 5 , and the resisting member 15 can be made of elastic material.
