摘要： The invention relates to a device for locking the end positions of movable switch parts and, in particular, the movable point (1) of a frog, in which two relatively axially displaceable parts are capable of being displaced into a position coupled with each other in a positive manner in at least one direction of movement, wherein the relatively displaceable parts are comprised of a tube (5) and a rod (6) guided within the tube (5) and are at least partially arranged in a stationary outer tube (4), whereby locking members (8) cooperate with the relatively axially displaceable parts (5, 6) as well as the outer tube (4) and are capable of being displaced in the radial direction into a locking position in a recess or inner annular groove (15, 16) of the outer tube (4). Said device is designed such that the outer tube (4) is comprised of two tube parts (17, 18) capable of being axially displaced within each other, and that each tube part carries at least one recess or inner annular groove (15, 16).

摘要： PROBLEM TO BE SOLVED: To improve both weight saving and durability of a switch for dissolving any problem on transportation business and also providing its durability for a long period use. SOLUTION: An action rod 3 is connected to tongue rails 2a, 2b and also this action rod is moved by means of an action cylinder 4. Thus constituted action rod 3 is provided with lock piece holding parts 5a, 5b and also a lock piece 7 is hooked on these lock piece holding parts so as to maintain the switching state of the tongue rails. Meanwhile, in order to release the lock pieces from the lock piece holding parts, a chain lock main cylinder MC is actuated so as to allow the lock pieces to retreat from the moving locus of the lock piece holding parts.
