Supporting structure of draft gears and rail vehicle

The invention discloses a supporting structure and a rail vehicle. The supporting structure comprises a coupler middle-front supporting structure body and a coupler tail frame middle supporting structure body, wherein the coupler middle-front supporting structure body is fixed on a vehicle body and used for supporting a coupler, the coupler tail frame middle supporting structure body is fixed on acoupler box fixing part and used for supporting the middle of a coupler tail frame, after an anchoring force connecting piece is snapped, a coupler tail pin supporting bolt mounting seat on the coupler tail frame can abut against the coupler tail frame middle supporting structure body, and a supporting seat of the coupler tail frame middle supporting structure body is cut off. According to the supporting structure, due to the fact that the distance between the rear end of the coupler tail pin supporting bolt mounting seat on the coupler tail frame and the front end of the coupler tail frame middle supporting structur
