Abstract
The utility model discloses a double-swing-door seal strip for a rail transit vehicle in the field of rail transit. The double-swing-door seal strip comprises a sealing body 1 and a sealing body 2, wherein a bump and a groove which are mutually matched are arranged on opposite sides of the sealing body 1 and the sealing body 2 respectively; the bump is arranged on the sealing body 1; the groove is formed in the sealing body 2; symmetrically stretching sealing edges are arranged on the two sides of the groove respectively; the middle parts on the sides, opposite to the matched sides, of the sealing body 1 and the sealing body 2 are provided with plug parts respectively; the bump is in transition connection with two side faces on the sealing body 1 through wedged surfaces; when a door is closed, the sealing edges are closely attached to the two wedged surfaces; meanwhile, the bump is inserted into the groove to be attached to the inner side of the groove. The double swing door seal strip has the advantages of simple structure, convenience in manufacturing, and dust prevention, water proofing, wind resistance and sound insulation effects, and can be applied to the double swing door of the rail vehicle.
Description
Technical field
The utility model relates to a kind of track traffic vehicle door sealing device, and particularly a kind of door weather strip, belong to field of track traffic.
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 traffic vehicles clamshell doors sealing band, makes the rail vehicle door favorable sealing property, can resist blast air to impact, and has good sound insulation, dustproof and cushioning effect.
The purpose of this utility model is achieved in that a kind of rail traffic vehicles clamshell doors sealing band, comprise sealing member one and sealing member two, described sealing member one and sealing member two side in opposite directions is respectively equipped with projection and the groove cooperatively interacted, described projection is arranged on sealing member one, described groove is arranged on sealing member two, the both sides of described groove are respectively equipped with the sealing lip of symmetrical abduction, the opposing middle side part of described sealing member one sealing member two is provided with Plug Division separately, on described projection and sealing member one, two sides excessively are connected through lozenges, during closing of the door, described sealing lip abuts on two lozenges, simultaneously, described projection is inserted in groove and is fit together with the groove inboard.
The car door of guideway vehicle is for to open the door to parallel-moving type, sealing member one of the present utility model and sealing member two are arranged on clamshell doors a side in opposite directions, sealing member one and sealing member two are made by elastomeric material, it has softness, waterproof, the resistant to corrosion characteristics, sealing member one and sealing member two can be protected the passenger when car door opening, avoiding the car door of hard damages, when closing of the door, sealing lip abuts on lozenges, form the two seals line, simultaneously, projection is inserted in groove, projection contacts with the groove inboard, the sealing of formation face, described sealing has good wind resistance, waterproof effect, potted line can further strengthen its sealing effectiveness, guaranteed on the whole the dustproof of car door, waterproof, wind resistance and soundproof effect.Compared with prior art, the beneficial effects of the utility model are: this apparatus structure is simple, easily manufactured, and it is applied on the opposite opened car door of guideway vehicle, has dustproof, waterproof, wind resistance and soundproof effect.
During for further assurance closing of the door, can form good sealing between sealing member one and sealing member two, in described sealing member one, be provided with along its length deformation and adapt to hole one, in described sealing member two, be provided with along its length deformation and adapt to hole two.When being subjected to the external force extruding, deformation adapts to hole, and deformation can occur, and makes sealing member one and sealing member two-phase contact part potential energy fit together better, is easy to realize sealing; Deformation adapts to arranging of hole and has reduced material usage, is a kind of comparatively economic way.
For fear of sealing member one and sealing member two, be offset when the crush seal mutually, described deformation adapts to the interior close protruding bilateral symmetry in hole one and is provided with concave surface one; Described deformation adapts to two middle side parts in hole two and is arranged with concave surface two.Concave surface one and concave surface two are area of stress concentration, thereby at described two concave surface places, bend while making sealing member one and sealing member extruding, thereby avoid being offset, and affect its sealing property.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model fundamental diagram.
Wherein, 1 sealing member one, 101 Plug Division, 102 projections, 103a, 103b lozenges, 104 deformation adapt to hole one, 105a, 105b concave surface one, 2 sealing member two, 201 Plug Divisions, 202 grooves, 203a, 203b sealing lip, 204 deformation adapt to hole two, 205a, 205b concave surface two, 3a, 3b clamshell doors.
