Abstract
The invention relates to a rail vehicle floor pressing strip, which is a strip profile. The pressing strip comprises a pressing strip main body, wherein the cross section of the pressing strip main body is formed by connecting a transverse strip and an inclined strip through an arc transition part, the transverse strip is fixedly connected with an outer underframe through a fastener, a support leg extends from one side, away from the transverse strip, of the transition part and is in contact with the outer underframe, the top surface of the transverse strip is provided with one group of spaced grooves, the bottom of the transverse strip is provided with a depression, the tail end, away from the inclined strip, of the transverse strip is provided with an overlapping joint which is in contact with the outer underframe, an elbow head extends from the tail end, away from the transverse strip, of the inclined strip and is in contact with an outer side wall plate, and the side surface, near the outer side wall plate, of the inclined strip is fixedly connected with an elastic strip which is abutted against the outer side wall plate. The pressing strip has the advantages that the modularizing degree is high, and the single detachment is realized on the basis of meeting the requirement of the floor pressing strip.
Description
Technical field
The present invention relates to a kind of floor of railway vehicle press strip, be particularly useful for railcar.
Background technology
According to the knowledge of the applicant, Layering of floors in in-built for guideway vehicle, requirement can realize the transition between in-built underframe and framed side wallboard, play beauty function, simultaneously can make up the vacancy between underframe and framed side wallboard, prevent that the water in guest room from entering underframe and framed side wallboard inside, want in addition wear-resisting anti-delineation.
Although existing Layering of floors can meet the demands on structure function, modular design is thorough not, and the later stage is easy care not.If, while need changing chassis component such as floor cloth, aluminium cellular components, not only will remove Layering of floors, also to remove the even side wall module parts such as seat of the framed side wallboard that is connected with it, increased production and maintenance intervals and the maintenance cost of product.
Through retrieval, find special Layering of floors patent for guideway vehicle, Patents for other fields such as household, automobiles is only arranged, the disclosed a kind of Layering of floors with soft limit of application number 201120328508.6 Chinese utility model patent for example, and that these patents can't be applicable to guideway vehicle is in-built, be difficult to use for reference.
Summary of the invention
Technical matters to be solved by this invention is: overcome the problem that prior art exists, a kind of floor of railway vehicle press strip is provided, the degree of modularity is high, can on the basis that meets the Layering of floors requirement, realize dismounting separately.
The technical scheme that the present invention solves its technical matters is as follows:
The floor of railway vehicle press strip, be rectangular section bar, comprises the press strip main body, it is characterized in that, described press strip main body section is formed by connecting through the arc-shaped transition parts by Cross slat and oblique, and described Cross slat is connected through fastener and outside underframe; Described transition member is towards away from a side of Cross slat, extending and the contacted supporting leg of outside underframe; The end face of described Cross slat has one group of groove spaced apart, and the bottom surface of described Cross slat has depression, and described Cross slat has and the contacted lap joint of outside underframe away from the end of oblique; Described oblique the end away from Cross slat is towards away from the Cross slat direction, extending and the contacted elbow of outer side wallboard; Described oblique the side near the outer side wallboard is fixed with the elastic strip offseted with the outer side wallboard.
In this structure, supporting leg can play reinforcement and position-limiting action, avoids when mounted oblique because excessively bending and break; Cross slat end face groove and bottom surface depression can fully discharge the stress that in installation process, Cross slat produces, and avoid Cross slat to break; Cross slat lap joint and oblique elbow can with outside underframe or framed side wallboard is seamless join, and play sealing function; Elastic strip can further guarantee the sealing of whole press strip and framed side wallboard, and can meet press strip and install by self deformation the time to the demand of controllability.After adopting this structure, whole press strip is a module, and itself and framed side wallboard are closely offseted and be fixed on underframe, namely with appearance attractive in appearance, realizes the transition between underframe and framed side wallboard, and making up the vacancy between underframe and framed side wallboard, anti-sealing enters underframe and framed side wallboard inside in guest room.Simultaneously, press strip be can dismantle separately when needed, framed side wallboard and side wall module parts can not brought disaster to.
The present invention further perfect technical scheme is as follows:
Preferably, the cross section of described elastic strip comprises and oblique the vertical edges be connected towards the side of framed side wallboard, and described vertical edges is connected towards the side of framed side wallboard and the two ends of semicircular ring, and the described semicircular ring outside is arranged with upper and lower buffering muscle.Elastic strip is played a role better.
Preferably, described oblique has the radian that bends towards framed side wallboard.
Preferably, the depression of described Cross slat bottom surface zone of living in covers the some grooves of end face zone of living in.
Preferably, described Cross slat, oblique, transition member are one-body molded.
The degree of modularity of the present invention is high, can on the basis that meets the Layering of floors requirement, realize dismounting separately.
