[0011] In a further embodiment, the locking mechanism is designed as a slotted structure whose open end is directed downwards, so that the wheel chock is not detached from the rail.
[0012] In a further embodiment, the operating device comprises an actuating handle which is connected to one end of a second connecting element, wherein the second connecting element is rotatably connected to a third connecting bolt and the second connecting bolt, wherein the second connecting bolt is inserted successively through the first pin hole of the base plate and the second pin hole of the connecting plate into the mounting bore of the rail.
[0013] In a further embodiment, the rail is provided with several mounting holes, which serve to install a connecting bolt of the support element and a pin shaft on the base plate of the stop.
[0014] In a further embodiment, it is provided that the first connecting piece is equipped with a cylindrical through-hole and a conical through-hole.
[0015] The present disclosure relates to a second problem, namely to provide a wheel chock used in a vehicle for rail transport.
