[0027] Under the push of the first spring 44, the sliding top plate 42 can be pressed against the fixed plug plate 43, and the fixed plug plate 43 is inserted into the fixed groove, so that the LED sign 3 can be fixed. After that, by squeezing the sliding pressure plate 46, the sliding top plate 42 can be pushed to slide by the push rod 45, so that the fixed plug plate 43 is separated from the inside of the fixed groove, which makes it convenient to release the fixation of the LED sign 3, making it more convenient to disassemble and assemble the LED sign 3, and facilitating the maintenance and replacement of the subway train safety escape sign.
[0028] like Figure 4As shown, the present invention provides a subway train safety escape sign, the fixed plug plate 43 includes a sliding plug plate 431, the sliding plug plate 431 is fixedly connected to the side of the sliding top plate 42 away from the first spring 44, the sliding plug plate 431 is provided with a sliding groove 2, the sliding groove 2 is slidably connected to a T-shaped push plate 433, the T-shaped push plate 433 is fixedly connected to the side of the sliding top plate 42 close to the second spring 432, the end of the T-shaped push plate 433 away from the sliding top plate 42 passes through the outer surface of the sliding plug plate 431 and is fixedly connected to the extrusion plate 434, the front and rear sides of the T-shaped push plate 433 are movably connected to a connecting rod 435, the end of the connecting rod 435 away from the T-shaped push plate 433 is movably connected to a fixed pressure plate 436, and the two fixed pressure plates 436 are slidably inserted into the front and rear sides of the sliding plug plate 431 respectively;
[0029] When the LED sign 3 is fixed by the fixed plug plate 43, as the sliding top plate 42 pushes the sliding plug plate 431 into the interior of the fixed groove, the extrusion plate 434 can be squeezed and the T-shaped push plate 433 can be pressed to slide, thereby squeezing the second spring 432, and the fixed pressure plate 436 can be pushed by the connecting rod 435 to press the inner wall of the fixed groove, so that the fixing effect is better.
