It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may be present. As used herein, "vertical," "horizontal," "left," "right," and similar expressions are for purposes of illustration only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Fig. 1 to 4 show a high-speed railway safety door anti-dislocation pedal structure according to a preferred embodiment of the utility model, which comprises a frame assembly 1 and a pedal assembly 2. The frame assembly 1 is located right below the pedal assembly 2 to support the frame assembly 1. The frame assembly 1 comprises a plurality of mutually independent segment frames 11 which are connected end to end, so that the frame assembly 1 is in a long strip structure. The pedal assembly 2 includes a plurality of independent and end-to-end sections of pedals 21, so that the pedal assembly 2 has a long structure. The connecting gap between two adjacent segment frames 11 is a first gap 12, the gap between two adjacent segment pedals 21 is a second gap 22, and the first gap 12 and the second gap 22 are distributed along the extending direction of the frame assembly 1 in a staggered manner, so that the segment pedals 21 are supported by at least two segment frames 11. The arrangement is such that the first slit 12 and the second slit 22 do not overlap, thereby preventing the mounting accuracy of the adjacent-segment step plate 21 from being affected by the dimensional error or mounting error of the adjacent-segment frame 11; moreover, since the segment step 21 is supported by at least two segment frames 11, the degree of influence of the first slits 12 on the mounting stability of the segment step 21 can be reduced, that is, each segment step 21 is not or less influenced by the first slits 12 during mounting and use, so as to prevent the segment step 21 from warping. And, utilize first gap 12 and second gap 22 along the extending direction dislocation distribution of frame assembly 1 for fasten with crisscross fixed form between frame assembly 1 and the footboard assembly 2, make whole high-speed railway emergency exit dislocation prevention footboard structure link into a more firm whole. Obviously, the high-speed railway emergency exit dislocation prevention footboard structure at this moment can be used for not only being the threshold of emergency exit, but also can be used for being whole waiting platform.

Preferably, each segment of the tread plate 21 is carried by two segment frames 11. This arrangement not only strengthens the connection strength between the adjacent segment frames 11 by one segment step 21, but also reduces the degree of influence of the segment step 21 by the first slit 12 as much as possible. Moreover, this is also for more firmly mounting the segment step 21 on the segment frame 11.

Preferably, the segment pedal 21 is fixedly connected with the segment frame 11 by means of screws 3. Obviously, the segment pedal 21 and the segment frame 11 may be fixed by welding.

The segment frame 11 is provided with a guide rail 4, and the avoidance groove 213 is used for allowing a mechanism above the segment pedal 21 to downwards pass through the avoidance groove 213 to be movably matched with the guide rail 4. It is apparent that the high-speed rail safety door dislocation prevention step structure in this case is mainly used as a support rail of the movable safety door, and the avoidance groove 213 is an indispensable important feature for preventing passengers from getting caught on the vehicle and hiding the guide rail 4. Moreover, on the premise of avoiding the groove 213, the upper end surface of the pedal assembly 2 can be relatively flat, and it is more important to prevent the step-up phenomenon of the segmental pedal 21. More preferably, more steady when being used for the high-speed railway emergency exit in order to make high-speed railway emergency exit dislocation prevention footboard structure, curb plate 212 is equipped with two at least, and the relative both sides of main part board 211 are located respectively to two blocks of curb plates 212. It is understood that two evacuation grooves 213 are provided in this case.

Preferably, the frame assembly 1 is provided with a rack assembly 5, and the extending direction of the rack assembly 5 is consistent with the extending direction of the frame assembly 1. With this arrangement, it is possible to allow the mechanism engaged with the guide rail 4 to be accurately moved by the rack assembly 5 by receiving force and transmitting force by the rack assembly 5. Preferably, the rack assembly 5 includes a plurality of segment racks 51 which are independent from each other and connected end to end, a connection gap between two adjacent segment racks 51 is a third gap, and the first gap 12, the second gap 22 and the third gap are distributed along the extending direction of the frame assembly 1 in a staggered manner, so that the segment racks 51 are supported by at least two segment frames 11.
