Abstract
The application discloses seal installation interface in wind gap is sent back to to air conditioner for track traffic including the automobile body, set up in the air conditioning unit at automobile body top and set up in automobile body and air conditioning unit rubber seal between the two, is located air conditioning unit send the air conditioning unit bottom plate of wind gap below back to on be provided with the ring groove that a cross -section is the U type, be provided with in this ring groove that the round is sealed to be filled up, should the sealed lower surface that fills up with rubber seal's the sealed cooperation of upper surface elasticity. Ring groove have annular outer baffle and annular in the baffle, and the height that highly is greater than the sealed pad of packing in ring groove of outer baffle. After adopting above -mentioned structure, can solve because air conditioning unit bottom plate plane degree is relatively poor, easily produce the gap, have water and ooze the into interior technical problem of car from this, can guarantee whole the sealed reliable of wind gap of sending back to. In addition, can also block effectively that water to rubber seal's direct impact, reduces rubber seal's ages at a rate.
Description
Technical field
The application relates to the sealing mounting interface that a kind of air-conditioning sealing system of rail traffic vehicles, particularly a kind of rail transit used air-conditioner send air port back to.
Background technology
Install for convenience of air-conditioner set, railcar more and more adopts the air-conditioner set of return air under lower air-supply, and air-conditioner set sends the sealed interface structure at air port place back to, directly affects the waterproof seal of vehicle.Existing air-conditioner set adopts rubber seal directly to crimp, and realizes sealing by the elastic deformation of rubber seal.
After air-conditioner set is installed, bottom it and between roof, there is certain gap, and sending back to after air port is connected with roof opening bottom air-conditioner set requires to prevent from leaking out to leak.Existing vehicle installs rubber seal in roof opening surrounding draw-in groove, by the deadweight compresses seal of air-conditioner set, realizes this function.
Adopt rubber seal to be directly pressed in air-conditioner set upper type, because air-conditioner set base plate plane degree is poor, easily produce gap, there is water and infilter risk in car from this.On rainy day, rainwater can connect and impact seal ring and air-conditioner set interface, if there is gap at this place, has the risk of seepage.
Utility model content
The technical matters that the application will solve is for above-mentioned the deficiencies in the prior art, and the sealing mounting interface providing a kind of rail transit used air-conditioner to send air port back to, the sealing mounting interface that this rail transit used air-conditioner sends air port back to can solve because air-conditioner set base plate plane degree is poor, easy generation gap, there is water and infilter technical matters in car from this, can ensure that whole sealing of sending air port back to is reliable.In addition, effectively block water to the direct impact of rubber seal, the aging speed of rubber seal can also be reduced.
For solving the problems of the technologies described above, the technical scheme that the application adopts is:
A kind of rail transit used air-conditioner sends the sealing mounting interface in air port back to, comprise car body, be arranged at the air-conditioner set of car body top and be arranged at car body and air-conditioner set rubber seal between the two, the air-conditioner set base plate of sending back to below air port being positioned at described air-conditioner set is provided with the U-shaped annular recess in a cross section, be provided with a circle packing seal in this annular recess, the lower surface of sealing pad and the upper surface elastic seal of described rubber seal are fitted.
Described annular recess has the outer baffle of ring-type and the Internal baffle of ring-type, and the height of outer baffle is greater than the height of the packing seal be filled in annular recess.
The height of described Internal baffle is less than or equal to the height of the packing seal be filled in annular recess.
Described annular recess is welded on described air-conditioner set base plate.
Described car body top is provided with draw-in groove, and described rubber seal is arranged in this draw-in groove.
Described packing seal is bonded in described annular recess.
After the application adopts said structure, there is following beneficial effect:
1. the packing seal in above-mentioned annular recess coordinates with rubber seal elastic seal, avoid rubber seal directly to contact with air-conditioner set base plate, also namely avoid because air-conditioner set base plate plane degree is poor, easy generation gap, and the water caused infilters the technical matters in car, thus make whole sealing of sending air port back to reliable.
2. the height of above-mentioned outer baffle is greater than the height of the packing seal be filled in annular recess, therefore effectively block water to the direct impact of rubber seal, can reduce the aging speed of rubber seal.

Detailed description of the invention
Below in conjunction with accompanying drawing and concrete better embodiment, the application is described in further detail.
As shown in Figure 1, a kind of rail transit used air-conditioner sends the sealing mounting interface in air port back to, comprises air-conditioner set 1, annular recess 12, packing seal 15, rubber seal 2 and car body 3.
As depicted in figs. 1 and 2, it has air-conditioner set base plate 11 and sends air port 16 back to the structure of above-mentioned air-conditioner set 1.
The top of above-mentioned car body 3 is provided with draw-in groove, and rubber seal 2 is arranged in this draw-in groove.
In prior art, the upper surface of above-mentioned rubber seal 2 directly contacts with air-conditioner set base plate 11, when air-conditioner set base plate 11 not at ordinary times, will produce gap between rubber seal 2 and air-conditioner set base plate 11, water electrode easily enters in car body 3 from gap location seepage.
In the application, as shown in Figure 3, the air-conditioner set base plate 11 of sending back to below air port 16 of air-conditioner set 1 is provided with the U-shaped annular recess 12 in a cross section, and annular recess 12 is preferably welded on air-conditioner set base plate 11.
Be provided with a circle packing seal 15 in above-mentioned annular recess 12, packing seal 15 is preferably bonded in annular recess 12.
The lower surface of above-mentioned packing seal 15 coordinates with the upper surface elastic seal of rubber seal 2, thus avoid rubber seal 2 and directly contact with air-conditioner set base plate 11, also namely avoid because air-conditioner set base plate plane degree is poor, easy generation gap, and the water caused infilters the technical matters in car, thus make whole sealing of sending air port back to reliable.
Further, above-mentioned annular recess 12 has the outer baffle 13 of ring-type and the Internal baffle 14 of ring-type, and the height of outer baffle 13 is greater than the height of the packing seal 15 be filled in annular recess 12.
Further, the height of above-mentioned Internal baffle 14 is less than or equal to the height of the packing seal 15 be filled in annular recess 12.
The height of above-mentioned outer baffle 13 is greater than the height of the packing seal 15 be filled in annular recess 12, therefore can effectively block water to the direct impact of rubber seal 2, there is safeguard function, and the impact of ultraviolet on rubber seal 2 can be effectively reduced, reduce the aging speed of rubber seal 2.
More than describe the preferred implementation of the application in detail; but the application is not limited to the detail in above-mentioned embodiment, within the scope of the technical conceive of the application; can carry out multiple equivalents to the technical scheme of the application, these equivalents all belong to the protection domain of the application.
