[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0032] As shown Figures 1 - 5 in the figure, a lighting component for a power distribution cabinet includes a cabinet body 1 with a cabinet door 2. The cabinet door 2 is hinged to the cabinet body 1. Inside the cabinet body 1, there is an installation rack for installing components. The installation rack is fixedly installed inside the cabinet body 1 by welding or bolts. Multiple through holes for component installation are formed on the installation rack. A lighting member is provided on the surface of the installation rack. It further includes:

[0033] A push switch 8 for controlling the on / off of the lighting member: The push switch 8 is fixedly installed on the side wall of the cabinet body 1 through a switch base 7. The push switch 8 is fixedly connected to the switch base 7 by bolts, and the switch base 7 is fixedly connected to the cabinet body 1 by bolts. An extrusion member matching the push switch 8 is provided on the inner side of the cabinet door 2. When the cabinet door 2 is closed, the extrusion member will extrude the push switch 8, causing the push switch 8 to close, that is, causing the lighting member to turn off, improving the portability during the use by the staff. Closing the door and turning off the light are synchronized, avoiding the situation that the staff forgets to turn off the light after closing the door and it is difficult to be discovered, resulting in waste of electric power resources. At the same time, after the door is opened, the lighting member will not automatically turn on. In the case of sufficient light, work can be carried out without turning on the lighting member. When it is necessary to turn on the light, manually press the push switch 8, further reflecting the power-saving function.

[0034] Furthermore, the lighting member includes a mounting plate 5 and a lamp holder 6 fixedly provided on the surface of the mounting plate 5. A lighting lamp 3 is installed on the lamp holder 6. The lighting lamp 3 is detachably connected to the lamp holder 6, facilitating the replacement of the lighting lamp 3. The side of the mounting plate 5 away from the lamp holder 6 is fixedly connected to the installation rack through a connecting block. The lamp holder 6 is electrically connected to the push switch 8 through a wire. The lamp holder 6 and the push switch 8 are connected to the circuit inside the power distribution cabinet. When the push switch 8 is turned on, the lighting lamp 3 lights up. During use, multiple groups of lighting lamps can be installed in series to improve the lighting brightness.

[0035] Furthermore, the pressing member includes a threaded rod 12 and a Z-shaped plate 4 fixedly arranged on the surface of the cabinet door 2. The Z-shaped plate 4 is fixedly connected to the inner side of the cabinet door 2 by screws. A strip-shaped groove 10 for the threaded rod 12 to pass through and be installed is formed on the surface of the Z-shaped plate 4. Two nuts 14 are threadedly connected to the outer surface of the threaded rod 12. By rotating the nuts 14, the threaded rod 12 is fixed on the Z-shaped plate 4. A gasket 15 is arranged between the two nuts 14 and the Z-shaped plate 4. By providing the gasket 15, the stability of the installation of the threaded rod 12 is ensured. One end of the threaded rod 12 is provided with a pressing portion for pressing the push switch 8. During use, since there may be deviations in the position during the manual installation of the push switch 8, that is, there may be deviations in the up and down height of the push switch 8, or the push switch 8 may be installed closer to or farther from the cabinet body 1 relative to the cabinet body 1. Therefore, the installation position of the pressing member needs to be adjusted so that when the cabinet door 2 is closed, the push switch 8 can be pressed to close it. The specific operation is that the staff first loosens the two nuts 14, adjusts the position of the pressing member relative to the Z-shaped plate (that is, horizontal and vertical movement adjustments can be made), and after the adjustment is completed, the nuts 14 are tightened.

[0036] Furthermore, the pressing portion includes a threaded connection ring 13 and a mounting block 11. The threaded connection ring 13 is sleeved and fixed at the end of the threaded rod 12. One end of the mounting block 11 is provided with a threaded connection hole that matches the threaded connection ring 13. The threaded connection ring 13 and the mounting block 11 can be disassembled, which is convenient for installing and replacing the components inside the mounting block 11. The other end of the mounting block 11 is movably penetrated by a sliding rod 17. One end of the sliding rod 17 penetrates into the threaded connection hole and is fixedly provided with a limit seat 16. The other end of the sliding rod 17 is fixedly provided with a rubber block 18. A spring 20 is arranged between the limit seat 16 and the end of the threaded rod 12. After the rubber block 18 contacts the push switch 8, it is pressed to close the push switch 8, and at the same time, the spring 20 can be compressed. Since there may be errors in the manual adjustment of the pressing member, excessive pressing is avoided to prevent damage to the push switch 8.

[0037] Furthermore, a retaining ring 23 for restricting the movement of the threaded connection ring 13 is fixedly arranged inside the threaded connection hole. The thread rotation direction of the threaded connection ring 13 is opposite to that of the threaded rod 12. The rubber block 18 is fixedly connected to the sliding rod 17 by a screw 19. The rubber block 18 is formed with a mounting hole for the screw 19 to be installed. Two guide rods 21 are symmetrically and fixedly arranged on one side of the limit seat 16. A guide hole 22 that matches the guide rods 21 is formed at the end of the threaded rod 12. Under the sliding fit of the guide hole 22 and the guide rods 21, the stability of the horizontal sliding of the sliding rod 17 is ensured, and the rotation of the sliding rod 17 is avoided.

[0038] Furthermore, a wire routing rack 9 that matches the wire is fixedly arranged on the surface of the mounting rack. The wires are neatly sorted and hidden in the wire routing rack 9, improving the aesthetics inside the cabinet body 1.
