[0023] 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.
[0024] Reference Figure 1-5 A train passenger compartment lighting lamp that is easy to maintain includes a light box 1 and a light strip 2 arranged inside the light box 1. A first clamp 3 is fixedly connected to the lower surface of the light box 1, and a second clamp 4 is slidably connected to the side of the first clamp 3. The first clamp 3 and the second clamp 4 are both U-shaped. Two insertion rods 7 are fixedly connected to the side of the first clamp 3 near the second clamp 4. The second clamp 4 has two slots 8 that cooperate with the insertion rods 7 on the side near the first clamp 3.
[0025] It can be understood that by setting the first clamp 3 and the second clamp 4, the second clamp 4 slides on the surface of the insertion rod 7 through the slot 8, thereby separating the first clamp 3 from the second clamp 4, making it convenient to quickly take out the light cover 6 and facilitate the maintenance of the lighting lamp.
[0026] Specifically, the second clamping member 4 is clamped to the surface of the first clamping member 3 through a symmetrically arranged limit assembly 5. The limit assembly 5 includes a limit member 502 and two limit holes 503. The two limit holes 503 are respectively opened on the upper surface of the insertion rod 7 and the upper surface of the second clamping member 4. A connecting rod 501 is fixedly connected to the surface of the limit member 502. The end of the connecting rod 501 away from the limit member 502 is rotatably connected to the inside of the insertion rod 7 through a rotating shaft. A spring 504 is provided on the lower surface of the connecting rod 501 for inserting the limit member 502 into the limit hole 503. The upper end of the limit member 502 is conical.
[0027] It can be understood that by setting the limit member 502, the spring 504 drives the limit member 502 and the connecting rod 501 to rotate through the rotating shaft, so that the limit member 502 is inserted into the limit hole 503, thereby limiting the position of the second clamping member 4, and fixing the light cover 6 to prevent the light cover 6 from loosening or even falling due to the vibration generated by the train running.
[0028] Specifically, the surfaces of the first clamping member 3 and the second clamping member 4 are detachably connected to the light-transmitting cover 6, and the inner sides of the first clamping member 3 and the second clamping member 4 are respectively provided with a slot 11 for clamping the light-transmitting cover 6. The inner walls of the two slots 11 are provided with rubber pads, and the edges of the light-transmitting cover 6 are all provided with inclined surfaces. Two baffles 13 are symmetrically fixed on the inner side of the second clamping member 4.
[0029] It is understandable that by providing two slots 11 , the two sides of the light-transmitting plate are clamped on the inner walls of the two slots 11 , thereby quickly clamping and fixing the light-transmitting cover 6 , and under the action of the two baffles 13 , the middle part of the light-transmitting cover 6 is prevented from bending downward.
[0030] Specifically, a magnetic block 9 is fixedly connected to the lower surface of the limiting member 502 , and two positioning rings 10 corresponding to the positions of the limiting holes 503 are provided on the lower surface of the second clamping member 4 .
[0031] It can be understood that by setting up the magnetic block 9, it is convenient to use a magnet to attract the magnetic block 9 and the limiting member 502, so that the limiting member 502 is separated from the limiting hole 503, and the limitation on the second clamping member 4 is released. By setting up the positioning ring 10, it is convenient to prompt the positioning of the placement of the magnet.
[0032] Specifically, the light strip 2 is detachably mounted on the inner wall of the light box 1 via a plurality of mounting rods 12 . The plurality of mounting rods 12 are all L-shaped, and their openings face the same direction. Rubber pads are disposed on the inner sides of the plurality of mounting rods 12 .
[0033] It is understandable that by providing a plurality of mounting rods 12 , the light strip 2 can be quickly mounted and fixed. Under the action of the rubber pad, the light strip 2 is protected and the fixing effect is improved.
[0034] In the present invention, the lighting is embedded in the train passenger compartment for lighting. When maintenance is required, two magnets are placed at the positions of the two positioning rings 10 respectively. Under the attraction of the magnets and the magnetic block 9, the limiting member 502 is driven to rotate downward through the connecting rod 501 and disengage from the limiting hole 503, thereby releasing the limit on the second clamping member 4. Then, the second clamping member 4 is pulled to slide on the surface of the insertion rod 7, so that the card slot 11 and the baffle 13 are disengaged from the light-transmitting cover 6. Then, the light-transmitting cover 6 is pulled toward the direction of the second clamping member 4 to remove the light-transmitting cover 6. During maintenance work, when the light strip 2 needs to be replaced, the light strip 2 is moved toward the opening direction of the mounting rod 12, out of the fixed range of the mounting rod 12, and the light strip 2 is replaced. Then, the light cover 6 is inserted into the slot 11 of the first clamp 3 again, and the second clamp 4 is slid and clamped to the two ends of the light-transmitting plate through the slot 11, so that the spring 504 pushes the limiting member 502 to be inserted into the limiting hole 503, and the second clamp 4 is limited and fixed. At the same time, the lower surface of the light cover 6 is lifted by the baffle 13 to prevent the light cover 6 from bending downward.

Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
