Abstract

The invention relates to a built-in closed sliding door for a railway vehicle, which comprises a door leaf, a lower guide rail, an outer baffle and an inner baffle, wherein the door leaf is arranged between the outer baffle and the inner baffle, and the lower part of the door leaf is inserted into a guide groove formed in the lower guide rail. The built-in closed sliding door further comprises an upper sealing rubber strip, a lower sealing rubber strip and a rear sealing rubber strip which are arranged at the upper part, the lower part and one side, close to the inside of the vehicle, of the door leaf respectively, wherein two sealing lip edges are arranged on the rear sealing rubber strip; and the upper sealing rubber strip, the lower sealing rubber strip and the rear sealing rubber strip are integrally clamped with the door leaf. The sliding door further comprises an upper guide rail for guiding the motion of the door leaf, and a vertically downward motion stroke is set in a position, where the door leaf is closed, of the guide rail. Compared with the prior art, the integral air tightness of the vehicle after the door leaf is closed is guaranteed; and the upper guide rail is arranged, so that poor opening and closing of the door leaf caused by the lap joint between the rubber strips and the vehicle body during normal operation of the door leaf is avoided.

Description

The built-in airtight door that moves of used for rail vehicle
Technical field
The present invention relates to a kind of rail vehicle door, specifically, is the airtight door that moves of a kind of built-in track.
Background technology
Built-in move is used in the rail vehicle as a kind of door that moves commonly used widely, it is arranged on door leaf in the car body, structure is simpler, the switch door is reliable, maintenance cost is also lower, but owing to have the slit between door leaf and the car body, and traditional move the adhesive tape that door only is provided for sealing on the contacted side of door leaf, after door leaf cuts out, its sealing effectiveness and soundproof effect are all very poor, and the door that has in the prior art installs hairbrush additional on door leaf, and it seals door leaf to a certain extent, but its effect still is not fine, and the passenger still can hear bigger noise in vehicle.
Summary of the invention
Goal of the invention: the built-in airtight door that moves that the object of the present invention is to provide a kind of good airproof performance.
Technical scheme: the present invention is realized by following technological means:
The airtight door that moves of the built-in formula of a kind of used for rail vehicle, comprise door leaf, lower guideway, car body, described car body comprises outer baffle and Internal baffle, door leaf is divided into left-hand door fan and right door leaf, door leaf is arranged between outer baffle and the Internal baffle, and insert in the gathering sill that is provided with on the lower guideway bottom of door leaf, also comprises sealing joint strip, lower seal adhesive tape and back sealing joint strip, and last sealing joint strip, lower seal adhesive tape and back sealing joint strip are separately positioned on a side of top, bottom and the close car body inside of door leaf.
The protuberance of enhanced leaktightness effect is set at the downside of lower seal adhesive tape.
On the sealing joint strip of described back two sealing lip limits are set, close when putting in place when door, two sealing lip limits compress external seal baffle plate and interior sealing plate respectively.
Last sealing joint strip, lower seal adhesive tape and back sealing joint strip and door leaf clamping are integral.
Also comprise the upper rail of guiding door leaf motion, described upper rail is arranged on the external seal baffle plate, and guide rail is provided with direction movement travel straight down on the fastening position of door leaf.
Beneficial effect: the present invention compared with prior art, it is by all being provided with airtight adhesive tape around door leaf, guarantee the vehicle overall tightness after door leaf cuts out, and be provided with a cover and have the guide rail of stroke straight down, stopped door leaf normal in service because overlap joint causes the not smooth situation of door leaf switch to take place between adhesive tape and the car body.

The specific embodiment
Below in conjunction with Figure of description the present invention is described in further detail:
As shown in Figure 1, the present invention relates to the built-in airtight door that moves of a kind of rail vehicle, comprise carrying guide driver 1, carrying dolly 2, left-hand door fan 3, right door leaf 4 reach guiding device 5 down, wherein carry dolly 2 and link to each other in carrying guide driver 1, left-hand door fan 3, right door leaf 4 connect the door-plate suspension bracket of corresponding carrying dolly bottom respectively, under insert the door leaf bottom in the gathering sill of guiding device 5.
Fig. 2 comprises screw mandrel 1.1, upper rail 1.2, stabilizer guide rail 1.3, transmission nut 1.4, transmission fork 2.1 for the structure of carrying guide driver, and carrying guide driver 1 connects screw mandrel 1.1, and transmission nut 1.4 is socketed on the screw mandrel,
Transmission fork 2.1 links to each other with transmission nut 1.4, thereby drives 2 motions of carrying dolly, and among the present invention, upper rail 1.2 is provided with a movement travel straight down on the position of closing the door, and like this, closes when door leaf and can add a sedimentation pressing action when putting in place.
Fig. 3 is the structure of following guiding device, comprise outer threshold 5.1, interior threshold 5.2, middle guide groove 5.3, draw runner 5.4 is provided with door leaf lower gear 4.1 in the bottom of door leaf, in the slideway that is provided with on the guide groove 5.3 in the middle of door leaf lower gear 4.1 is inserted in, gear installs in respect of draw-gear before the close door leaf of door leaf lower gear 4.1, can draw draw runner 5.4 and slide in slideway in the process of switch door.When being the door open mode, draw runner 5.4 is drawn to the zone of passing through of guide groove, covers the twice chute on the guide groove, plays the accessible function of passing through.
In the lower gear 4.1 of door leaf, be installed with lower seal adhesive tape 4.2, when door leaf is opened, in the middle of sealing joint strip 4.2 is suspended in the upside of guide groove 5.3 and with its maintenance space; When door leaf cuts out, door leaf moves downward under the effect of upper rail 1.2, the upper surface of guide groove 5.3 in the middle of lower seal adhesive tape 4.2 is pressed on downwards with door leaf, play the effect that compresses sealing, among the present invention, the bottom of described lower seal adhesive tape 4.2 also is provided with two protuberances, when lower seal adhesive tape 4.2 compresses centre guide groove 5.3, protuberance is held middle guide groove 5.3 tightly, makes sealing effectiveness better.
