Abstract
The utility model discloses a door seal strip of a rail transit train in the field of rail transit. The door seal strip comprises a mounting part, a fixing part and a sealing part, wherein the mounting part is a T-shaped bump; the mounting part is arranged on the left side face of the fixing part; the sealing part consists of a cambered strip and a convex strip; the middle part of the cambered strip is fixedly arranged on the top of the fixing part; one side of the cambered strip is provided with a lapping edge, and the other side of the cambered strip is provided with a sealing edge; the convex strip is fixedly arranged on the right side face of the fixing part. The door seal strip has the advantages of simple structure, convenience in manufacturing and better sound insulation, dust prevention and damping effects, and can be used for doors of the rail transit trains.
Description
Technical field
The utility model relates to a kind of rail vehicle door seal device, particularly the sealing band used of rail vehicle door.
Background technology
A kind of sealing band be arranged on arrangements for automotive doors is arranged in prior art, its patent No. is: 201220311885.3, the applying date: 2012.06.30, the sealing bar comprises the connecting portion of the closely knit glue system of EPDM on the doorframe that is adapted to be mounted within automobile, this connecting portion has the mounting groove be connected with the installation edge of doorframe, on connecting portion, have be suitable for the laminating of the door leaf of automobile, with the sealing of the EPDM gelatin sponge system of connecting portion one extrusion molding.Its weak point is, for motions at a high speed such as guideway vehicles, and the vehicle with larger air-flow noise, simple sealing is inadequate, it not only needs to have air-tightness, can tolerate the impact of airflow, need that simultaneously sound insulation is arranged, the effect of dustproof, damping, the above-mentioned effect of automobile sealing strip out of reach of the prior art.
The utility model content
The purpose of this utility model is to provide a kind of rail transit train door weather strip, makes the rail vehicle door leak tightness good, and has stronger anti-blast air impact property, simultaneously, has good sound insulation, dustproof and cushioning effect.
The purpose of this utility model is achieved in that a kind of rail transit train door weather strip, comprise installation portion, fixed part and sealing, described installation portion is T shape projection, and installation portion is arranged on the fixed part left surface, described sealing is comprised of arc strip and raised line, and described arc strip middle part is fixedly installed on the fixed part top, and described arc strip one side is landing edge, opposite side is sealing lip, and described raised line is fixedly installed on the fixed part right flank.
The utility model is arranged on the single opened car door, the installation that is complementary of groove on its installation portion and car door, be connected together mutually, and the landing edge on arc strip is overlapped on doorframe, play the effect of sealing, at closing time, the sealing lip on arc strip is overlapped on car body, plays the effect of first sealing, raised line is also conflicted on car body, play the effect of second sealing, its sealing property is better, and the arc strip structure has anti-blast air impact property preferably.Compared with prior art, the beneficial effects of the utility model are, the utility model is simple in structure, easily manufactured, have sound insulation preferably, dustproof and cushioning effect.The utility model can be used in the rail transit train car door.
In order to strengthen the fixing reliability of car door and the utility model, the end face of described installation portion is provided with arc groove.Arc convex on this arc groove and car door cooperatively interacts, and strengthens the friction force between car door and the utility model, thereby strengthens fixing each other reliability.
In order further to strengthen sound insulation, the dust-proof effect between the utility model and car door, the bottom of described fixed part is provided with the arc fin.This fin and car door fit together, and strengthen its sound insulation, dust-proof effect.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model working state figure.
Wherein, 1 fixed part, 101 fins, 2 installation portions, 201 arc grooves, 3 sealings, 301 arc strips, 301a landing edge, 301b sealing lip, 302 raised lines, 4 car doors, 5 doorframes.
The specific embodiment
A kind of rail transit train door weather strip as shown in Figure 1-2, comprise installation portion 2, fixed part 1 and sealing 3, installation portion 2 is T shape projection, and installation portion 2 is arranged on fixed part 1 left surface, sealing 3 is comprised of arc strip 301 and raised line 302, arc strip 301 middle parts are fixedly installed on fixed part 1 top, arc strip 301 1 sides are landing edge 301a, opposite side is sealing lip 301b, raised line 302 is fixedly installed on fixed part 1 right flank, the end face of installation portion 2 is provided with arc groove 201, and the bottom of fixed part 1 is provided with arc fin 101.
The utility model is made by elastomeric material, has certain elasticity, therefore when car door 4 is closed, certain deformation can occur in the sealing 3 in the utility model, deformation part is being pressed under elastomeric effect on doorframe 5, the contact form between sealing 3 and doorframe 5 by line to face, thereby complete sealing, and, by the sealing of twice face, strengthen its sealing property.
The utility model is not limited to above-described embodiment; on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in protection domain of the present utility model.
