Abstract
The utility model relates to a kind of rail traffic soft air ducts, including air duct tarpaulin and two mounting flanges for being fixed on air duct tarpaulin both ends, air duct tarpaulin includes the tarpaulin end plate of tarpaulin cylinder and tarpaulin cylinder both ends, the both ends of air duct tarpaulin are adhesively fixed by tarpaulin end plate with mounting flange after the inner hole of mounting flange, the back side of tarpaulin end plate and the front of mounting flange bond, and have the beading for sealing in the front of tarpaulin end plate.The utility model has the beneficial effects that：The problems such as structure is simple, light weight, can not only preferably solve air-tightness, waterproofness, high temperature resistant and anti-HV ray.Vehicle is not only dismantled in maintenance, is assembled fast, but also is more convenient for cleaning.
Description
Technical field
The utility model relates to a kind of rail traffic soft air ducts.
Background technique
Rail traffic is mainly used for the connection of car body and air-conditioning with soft air duct, can preferably compensate car body and air-conditioning unit
Error.Due to the particularity of soft air duct present position, it is therefore desirable to higher water proof type, anti-HV ray, air-tightness and resistance to
The performances such as high temperature.
Existing soft air duct primary structure is flange, silica gel tarpaulin, rivet, clip, sealing joint strip and sealant.Silica gel
After tarpaulin sews, tarpaulin, flange and clip are riveted together by rivet, silica gel tarpaulin is in flange and clip
Between, by surrounding gluing after the completion of staking.In order to guarantee air-tightness that soft air duct is connect with other component, splicing tape gum on flange
Foam, used foam be open type structure.
The shortcomings that existing soft air duct includes：1. existing structure is complicated and uses open type foam, cannot preferably expire
Sufficient air-tightness and waterproofness.2. sealant is externally exposed for a long time, easy degumming, cracking.3. there is no chamfering on flange, it has not been convenient to
Grafting is carried out with car body and air-conditioning.4. silica gel tarpaulin is harder, ductility is poor, cannot preferably compensate between car body and air-conditioning
Error.
Utility model content
Technical problem to be solved in the utility model is：A kind of rail traffic soft air duct is provided, product quality is improved.
Technical solution adopted by the utility model to solve its technical problems is：A kind of rail traffic soft air duct, including
Air duct tarpaulin and two mounting flanges for being fixed on air duct tarpaulin both ends, air duct tarpaulin includes tarpaulin cylinder and tarpaulin cylinder both ends
Tarpaulin end plate, the both ends of air duct tarpaulin are adhesively fixed by tarpaulin end plate with mounting flange after passing through the inner hole of mounting flange,
The back side of tarpaulin end plate and the front of mounting flange bond, and have the beading for sealing in the front of tarpaulin end plate.
To improve anti-HV ray and high temperature resistance, further limit, tarpaulin cylinder is aramid fibre cloth, paulin
Cloth end plate is aromatic polyamide resin, and tarpaulin end plate and tarpaulin cylinder are complex as a whole.
It for the intensity for increasing flange, further limits, the inner hole surrounding at the back side of mounting flange has flange.
To carry out grafting convenient for flange and car body and air-conditioning, further limit, the lower edge tool at the back side of mounting flange
There is the chamfering for being convenient for grafting installation.
The utility model has the beneficial effects that：Structure is simple, light weight, can not only preferably solve air-tightness, waterproofness,
The problems such as high temperature resistant and anti-HV ray.Vehicle is not only dismantled in maintenance, is assembled fast, but also is more convenient for cleaning.

Fig. 2 is the structural schematic diagram of the air duct tarpaulin of the utility model.
Fig. 3 is the stereoscopic-state figure at the back side of the mounting flange of the utility model.
Fig. 4 is the positive stereoscopic-state figure of the mounting flange of the utility model.
In figure, 1. air duct tarpaulins, 1-1. tarpaulin end plate, 2. mounting flanges, 3. beadings, 4. flange, 5. chamferings.
Specific embodiment
As shown in Fig. 1,2,3 and 4, a kind of rail traffic soft air duct, including air duct tarpaulin 1 and it is fixed on air duct tarpaulin 1
Two mounting flanges 2 at both ends, air duct tarpaulin 1 include the tarpaulin end plate 1-1 of tarpaulin cylinder and tarpaulin cylinder both ends, air duct tarpaulin
1 both ends are adhesively fixed by tarpaulin end plate 1-1 with mounting flange 2 after the inner hole of mounting flange 2, tarpaulin end plate 1-1's
The back side and the front of mounting flange 2 are bonded by 3M double faced adhesive tape, and the design of tarpaulin end plate realizes cancellation tarpaulin and flange turns over
The effect for needing staking to connect between side.In order to guarantee the air-tightness after connection and drenching with rain property, in the positive mask of tarpaulin end plate 1-1
There is the beading 3 for sealing.
In order to realize anti-HV ray and high temperature resistance, tarpaulin cylinder is aramid fibre cloth, tarpaulin end plate 1-1
For aromatic polyamide resin, tarpaulin end plate 1-1 and tarpaulin cylinder are complex as a whole.
The inner hole surrounding at the back side of mounting flange 2 has flange 4.
The lower edge at the back side of mounting flange 2 has to carry out the chamfering 5 of grafting installation with car body and air-conditioning.
Hole in figure on mounting flange 2 and tarpaulin end plate 1-1 is bolt hole, for inserting in mounting flange and car body and air-conditioning
Bolt is carried out after connecing to fix.
