The invention discloses a connected rail-holding lock. A radius-height difference is measured by utilizing a proportion of wheels, diameter of a rail surface circumcircle and diameter of a leaning side R, and accordingly the connected track-holding lock is designed. According to theory-based speculation, no matter which reason leads to derail and turnover, one wheel must surpass the upside of the rail, and the heading direction is changed after deviation to cause derail and turnover. When a vehicle climbs up the rail surface from the leaning side R, conditions for enabling the wheels and the vehicle body to rise must exist. Three different values in the width direction from the cross section of the rail, and the middle part is narrowest. Therefore, the part above the offline of the narrow surface of the rail cross section as a rail-holding lock inner hole profile. The upper end of the lock body is fixed on a vehicle body, a vehicle beam and a wheel axle based on the vehicle shape to keep the lock to be vertical to the center of the rail; gaps of the locking hole are matched to control the height of the wheels, the vehicle body and the rail. If the vehicle body, the wheels and the vehicle beam rise accidentally, the top lines of the two sides of the locking hole clamp the lower shoulder of the upper end of the rail to control the height of the vehicle beam and the rail as well as enable the leaning side R to be not able climb up the rail surface, so that derail and turnover is prevented. The connected rail-holding lock is simple to produce, convenient to maintain, durable in use and low in manufacturing cost.
