The specific embodiment

For above-mentioned purpose, the feature and advantage that make the utility model can be more obviously understandable, hereinafter is special to be lifted preferred embodiment and cooperates appended graphic elaborating.

Now cooperate the preferred embodiment of graphic explanation the utility model.

See also 2 figure, the locomotive master foot rest mechanism 100 of present embodiment is applicable among the locomotive M.

See also 3A figure and 3B figure, locomotive master foot rest mechanism 100 mainly includes the main foot rest of a vehicle frame 110, one 120, a spring retaining element 130 and a spring 140.

Main foot rest 120 is to be connected in vehicle frame 110 with rotating manner, and main foot rest 120 has one first connecting part 121.

Spring retaining element 130 has a locking section 131 and one second connecting part 132.Locking section 131 is to be attached to vehicle frame 110 with rotating manner.Second connecting part 132 is with respect to locking section 131, and second connecting part 132 has a long open-work 132a, a location flange 132b and a circle open-work 132c.At this, locating flange 132b is between long open-work 132a and circle open-work 132c.In addition, specifically, the distance between first connecting part 121 of long open-work 132a and main foot rest 120 is less than the distance between first connecting part 121 of circle open-work 132c and main foot rest 120.

Spring 140 has one first connecting end 141 and one second connecting end 142.First connecting end 141 is with respect to second connecting end 142, and first connecting end 141 is linked to first connecting part 121 of main foot rest 120.Among present embodiment, second connecting end 142 of spring 140 is that the long open-work 132a via second connecting part 132 of spring retaining element 130 is linked to round open-work 132c, and second connecting end 142 is the flange location that 132b keeps out that are positioned.More detailed, shown in Fig. 4 A, second connecting end 142 of spring 140 can be sheathed on earlier among the long open-work 132a of second connecting part 132 of spring retaining element 130.Then, shown in Fig. 4 B, first connecting end 141 of spring 140 is linked to first connecting part 121 of main foot rest 120.At this; Because the distance between first connecting part 121 of long open-work 132a and main foot rest 120 is less than the distance between first connecting part 121 of circle open-work 132c and main foot rest 120; So the assembling of spring 140 links meeting more or less freely (that is spring 140 is held the required application of force by stay bolt can be less).Then, among second connecting end 142 of spring 140 can progressively slide into round open-work 132c along long open-work 132a, thereby reach the purpose that is linked to round open-work 132c, shown in Fig. 3 A.At this moment, second connecting end 142 of the spring 140 flange location that 132b keeps out that can be positioned.More specifically, no matter how start of main foot rest 120, shown in Fig. 3 A and Fig. 3 B, second connecting end 142 of spring 140 all can be because of the keeping out the location and keep being linked to round open-work 132c of locating flange 132b, and can not slide among the long open-work 132a again.

As stated; Assembling process compared to the spring 40 of the locomotive master foot rest mechanism 1 of convention; The assembling process of the spring 140 of the locomotive master foot rest mechanism 100 of the utility model can seem less difficult relatively painstaking (having under the situation of identical elasticity modulus) at spring 40 and spring 140, and then can reduce the injured chance of assembler.
