[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figure 1-7 A train driver's cab ceiling light includes a light box 1 and a light strip 2 arranged inside the light box 1. The inner wall of the light box 1 is fixedly connected to a connecting tube 3, and the bottom of the connecting tube 3 is fixedly connected to a translucent lampshade 4. The light box 1 is stepped.

[0028] It is understandable that, by providing the connecting tube 3 , the fixing component 5 can be shielded to prevent light from shining on the fixing component 5 and generating lighting shadows.

[0029] Specifically, a plurality of fixing components 5 for fixing the light box 1 are distributed in an array in the interlayer formed by the light box 1 and the connecting tube 3. The fixing component 5 includes a fixing part 502 and a guide rod 501 for sliding the fixing part 502 up and down. The fixing part 502 is L-shaped and is an arc-shaped for easy storage in the interlayer. The fixing component 5 also includes a spring 503 for resetting the fixing part 502 and a top block 504 for pressing the fixing part 502 downward. The top block 504 is L-shaped, and the lower surface of the top block 504 is a downward inclined surface. The lower end of the guide rod 501 is rotatably connected to a mounting plate, and the mounting plate is fixed to the surface of the connecting tube 3. The upper end of the guide rod 501 is rotatably connected to the top of the inner wall of the light box 1. The spring 503 is sleeved on the surface of the guide rod 501, and the top block 504 is fixedly connected to the inner wall of the light box 1. A plurality of entrances and exits 6 for the fixing part 502 to enter and exit the light box 1 are provided on the surface of the light box 1.

[0030] It can be understood that, by rotating the guide rod 501, the fixing part 502 is driven to rotate outward from the light box 1. With the cooperation of the top block 504, the fixing part 502 is pressed downward. With the cooperation of the stepped shape of the light box 1, it is convenient to clamp the lighting lamp on the train ceiling, which is convenient for installation and achieves the purpose of firm fixation. By rotating the guide rod 501, the fixing part 502 is driven to rotate inward from the light box 1. The spring 503 is used to slide the fixing part 502 upward, so that the fixing part 502 is separated from the train ceiling, which is convenient for quickly removing the light box 1.

[0031] Specifically, a bottom ring 7 is rotatably provided on the inner wall of the connecting tube 3, and a transmission structure 8 is fixedly connected to the inner wall of the bottom ring 7 for driving the guide rod 501 to rotate. A connecting ring 9 is fixedly connected to the inner wall of the light box 1, and a connecting groove 10 is provided on the surface of the bottom ring 7 to cooperate with the connecting ring 9. The bottom ring 7 is rotatably connected to the surface of the connecting ring 9 through the connecting groove 10. The transmission structure 8 includes a gear 801 fixed to the lower end of the guide rod 501 and a gear ring 802 fixed to the inner wall of the bottom ring 7, and the gear 801 and the gear ring 802 are meshed with each other.

[0032] It is understandable that by rotating the bottom ring 7, the gear ring 802 is driven to rotate, and under the meshing relationship between the gear 801 and the gear ring 802, the guide rod 501 is driven to rotate, so that the fixing member 502 can enter and exit the box.

[0033] Specifically, a limiting groove 11 is formed on the surface of the guide rod 501 to prevent the fixing member 502 from rotating.

[0034] It is understandable that, by providing the limiting groove 11 , the fixing member 502 is prevented from rotating on the surface of the guide rod 501 , thereby limiting the fixing member 502 .

[0035] Specifically, a plurality of anti-slip protrusions 12 are provided on the lower surface of the bottom ring 7 .

[0036] It can be understood that the provision of the anti-slip protrusions 12 facilitates the rotation of the bottom ring 7 , and at the same time, the aesthetics of the lighting lamp can be improved by changing the shape of the anti-slip protrusions 12 .

[0037] In the present invention, the light box 1 is placed into a hole pre-opened on the train ceiling, the bottom ring 7 is rotated through the anti-slip protrusion 12, and the bottom of the light box 1 is pressed to prevent the light box 1 from rotating. The gear ring 802 is driven to rotate by the bottom ring 7, and under the meshing relationship between the gear 801 and the gear ring 802, the guide rod 501 and the fixing part 502 are driven to rotate out of the light box 1. At the same time, the fixing part 502 is pressed downward by the top block 504, so that the multiple fixing parts 502 are tightly pressed against the surface of the train ceiling, completing the fixed installation of the lighting lamp. When disassembly and maintenance are required, the bottom ring 7 is rotated in the opposite direction, so that the guide rod 501 drives the fixing part 502 to rotate into the light box 1. At the same time, under the action of the spring 503, the fixing part 502 slides upward on the surface of the guide rod 501, so that the light box 1 can be quickly removed.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
