In this way, it can be ensured that the door of the electrical control cabinet of the train will not be opened automatically when the train runs on uneven roadbed tracks and in harsh windy and sandy environment, the space in the cabinet has relative airtightness, the local wind and sand and the acid, alkali and salt mist contained in the air are prevented from eroding, and the filter cartridge container 61 arranged in the cabinet is particularly damped and clamped to ensure the safe and effective use of the filter cartridge container 61.

[0030] The anti-vibration snap fastener 2 comprises a fixed plate one 21, a fixed plate two 22 and an intermediate lap plate 23. One end of the fixed plate one 21 is fixed on the normally closed large door 11 by welding, and one end of the fixed plate two 22 is fixed on the cabinet body of the electrical control cabinet by welding to avoid loosening under strong vibration. One end of the intermediate lap plate 23 is lap-connected with the fixed plate one 21, and the other end is detachably connected with the fixed plate two 22. The intermediate lap plate 23 can be deformed and designed according to needs to adjust the setting distance between the fixed plate one 21 and the fixed plate two 22.

Anti-loosening spring washers 26 are arranged between the screw shank of the bolt 24 and the fixed plate one 21 and between the nut 25 and the fixed plate two 22.

[0032] The intermediate overlapping plate 23 is Z-shaped and is composed of an overlapping panel 231, a transition panel 232, and a connecting panel 233. The bolt holes on the intermediate overlapping plate 23 are located on the connecting panel 233. The connecting panel 233 of the intermediate overlapping plate 23 has a directional tube 27 on the side facing the second fixed plate 22. The bolt holes on the connecting panel 233 are connected to the tube holes of the directional tube 27. The bolts 24 are located in the tube holes of the directional tube 27, thereby ensuring that the axis of the bolts 24 is perpendicular to the connecting panel 233, so that the overlapping panel 231 can normally apply constraint pressure to the first fixed plate 21.

[0033] A shock-absorbing washer 28 is provided between the connecting panel 233 on the outer periphery of the directional tube 27 and the second fixing plate 22, which is compressed by the connecting panel 233 and the second fixing plate 22; the overlapping panel 231 of the intermediate overlapping plate 23 has a vibration-damping rubber layer 7 bonded by vulcanization on the side facing the first fixing plate 21, and the overlapping panel 231 of the intermediate overlapping plate 23 is pressed on the first fixing plate 21 through the vibration-damping rubber layer 7, thereby suppressing and attenuating the vibration of the intermediate overlapping plate 23 and the first fixing plate 21.

[0034] The triangular spindle lock 3 includes a triangular spindle 31, a bolt 32, and a limiting groove 33. The triangular spindle 31 is mounted on the normally open small door 12 and can rotate.
