Shock-absorbing anti-collision mechanism

A shock absorption anti-collision mechanism relates to a shock-absorbing device used for an air door of coal pits. The shock absorption anti-collision mechanism aims to solve the problem that a tramcar knocks against the air door hard, and provides the shock absorption anti-collision mechanism which can effectively slow the wallop of the tramcar. The shock absorption anti-collision mechanism comprises a sliding angle iron 1, a connecting bar 2, a limiting rubber block 3, an offsetting spring 4, a fixed angle iron 5, a supporting plate 6, a pothook 7, a connecting pin 8 and a connecting pole spacing 9, wherein, the fixed angle iron 5 and the sliding angle iron 1 are fixed with the supporting plate 6 and the pothook 7, the connecting pin 8 is arranged between the supporting plate 6 and the fixed angle iron 5, the connecting pin 8 is fixed with the connecting bar 2, the fixed angle iron 5 is provided with the connecting pole spacing 9, the pothook 7 is provided with the offsetting spring 4, and the fixed angle i
