A tool integrated cabinet for rail transit vehicles includes a shell, a pullable support frame, a damping universal roller and a folding seat storage cabin. The support frame is linearly guided through the sliding cooperation of a T-shaped guide rail and a clamping block. The stability of the support frame in a vehicle vibration environment is improved by the antiskid rubber material and damping design of the roller. The inside of the support frame adopts a modular partition structure. A fire extinguisher is fixed through the placement grooves of first and second support plates. The bottom plate cooperates with a guide groove to realize the quick taking and placing of an escape ladder. A groove is internally provided with a slide rail type folding seat storage cabin. The folding seat storage cabin is linked with a storage guide plate through a handle passage to realize the vertical partition management of emergency equipment and auxiliary tools. In addition, the conical self-locking structure and spring elastic pre-tightening mechanism of the plug rod and plug plate can effectively prevent the accidental sliding of the support frame. The combination innovation of the T-shaped guide rail, damping roller and folding cabin integration significantly enhances the safety and convenience of rail transit emergency equipment management.
