[0030] The buffering seat 31 will slide up and down in the sliding groove 36 on the L-shaped fixing seat 33 in cooperation with the sliding block 37, so as to limit the buffering seat 31 and prevent it from sliding left and right. During the sliding process, the damper 34 at the bottom of the buffering seat 31 will be compressed, so that the received shaking can be released through the compression of the damper 34, thereby ensuring the stability of the suspended ceiling structure layer.

[0031] The outer wall of each of the two dampers 34 is wound with a spring 35, one end of each of the two springs 35 is fixedly connected with the buffering seat 31, and the other end of each of the two springs 35 is fixedly connected with the L-shaped fixing seat 33.

[0032] The spring 35 on the outer wall of the damper 34 can reset it so that it can repeatedly buffer.

[0034] The buffering seat 31 will slide up and down in the sliding groove 36 on the L-shaped fixing seat 33 in cooperation with the sliding block 37, so as to limit the buffering seat 31 and prevent it from sliding left and right.

[0035] The right side of the L-shaped fixing seat 33 is provided with two circular grooves 38, the inner part of each of the two circular grooves 38 is in sliding connection with a threaded rod 39, and the right end of each of the two threaded rods 39 is provided with a mounting groove two 391.

Through this setting, when the position of the circular groove on the inner wall of the train is slightly deviated, this flexible fixing mode can also ensure the smooth installation of the L-shaped fixing seat, and increase the fault tolerance and convenience of installation.

[0040] The threaded rods 39 can be tightened by the nuts 394 on the outer walls of the threaded rods 39 matched with the two rotating connecting rods 392, so that the L-shaped fixing seat 33 can be fixed.

[0041] One specific application of the embodiment is: when multiple structure layers need to be replaced, the handle 291 is pulled outward, which drives the limiting rod 27 outward, and during the outward movement of the limiting rod 27, the limiting rod 27 will compress the spring I 29 on the outer wall of the limiting block 28 and the bar-shaped rod 26. Through this operation, the limiting of multiple structure layers can be released, thereby providing convenience for replacing the structure layer individually. The advantage of this design is that it greatly reduces the cumbersome disassembly process, saves time and labor cost, and effectively improves work efficiency; when the ceiling needs to be fixed, the circular groove 38 on the L-shaped fixing seat 33 is matched with the circular groove on the inner wall of the train, then the threaded rod 39 is inserted into the two circular grooves, and during the insertion process, the two connecting rods 392 rotatably connected on the threaded rod 39 will compress the spring II 393 thereon and simultaneously retract into the mounting groove II 391 on the threaded rod 39, so that the threaded rod 39 can pass through the two circular grooves without obstruction. When it is penetrated, the two connecting rods 392 will be unfolded under the pushing of the spring II 393 thereon, and then the nut 394 on the outer wall of the threaded rod 39 is rotated and matched with the two rotating connecting rods 392 to tighten the threaded rod 39, so that the L-shaped fixing seat 33 can be fixed. Through this setting, when the position of the circular groove on the inner wall of the train is slightly deviated during installation, this flexible adjustment fixing method can also ensure the smooth installation of the L-shaped fixing seat, increasing the fault tolerance and convenience of installation; after the L-shaped fixing seat 33 is fixed, the T-shaped sliding seat 1 of the ceiling structure layer is matched with the buffer seat 31 on the L-shaped fixing seat 33. When the ceiling structure layer is shaken during train operation, the ceiling structure layer will transmit the shaking to the buffer seat 31, and the buffer seat 31 will slide up and down in the sliding groove 36 on the L-shaped fixing seat 33, thereby limiting it, preventing it from sliding left and right, and the damper 34 on the bottom of the buffer seat 31 will be compressed during the sliding process. The shaking can be released by the compression of the damper 34, which can ensure the stability of the ceiling structure layer. At the same time, the spring 35 on the outer wall of the damper 34 can reset it so that it can repeat the buffering action. Through this setting, when encountering a curve or a bumpy section, this buffering structure can effectively absorb and resolve the impact force received by the ceiling structure layer, ensuring that the ceiling structure layer will not be damaged or loosened due to violent shaking, and providing a safe and stable riding environment for passengers.
