Abstract
The utility model discloses a connecting structure of a metro vehicle air duct, belonging to the technical field of an air-conditioning and ventilation system of the metro vehicles. The connecting structure comprises a pair of flanges which are respectively mounted on a first air shaft and a second air shaft, wherein the flange on the first air shaft is mounted at the outer side of the head face of the first air shaft, and the flange on the second air shaft is mounted at the inner side of the head face of the second air shaft. The connecting structure of the metro vehicle air duct is simple in structure, convenient in installation and operation, and high in working efficiency; the vehicle is conveniently and rapidly detached when being maintained; moreover, problems of poor sealing and inconvenient installation of an aluminous alloy air duct in connection are solved.
Description
Technical field
The utility model relates to the connection structure in a kind of railcar air channel, belongs to air conditioner of subway vehicle ventilation system technical field.
Background technology
At present the mode that adopts flange to connect together every section air channel is mostly installed in the aluminum alloy air channel of railcar, but that its shortcoming is a packaging efficiency is low, be inconvenient to dismantle, and also poorly sealed, cause the waste of energy.
The utility model content
The utility model technical matters to be solved is, overcomes the shortcoming of prior art, proposes the connection structure in a kind of railcar air channel, and not only packaging efficiency is high, and favorable sealing property, and is easy for installation.
In order to solve above technical matters, the utility model provides the connection structure in railcar air channel, comprises a pair of flange that is installed in respectively on first air channel and second air channel, and wherein the flange on first air channel is installed in the end face outside, said first air channel; Flange on second air channel is installed in the inboard of the said second air channel end face.
The technical scheme that the utility model further limits is: the connection structure in aforesaid railcar air channel, end face of flange on said second air channel and the said second air channel end face distance are less than or equal to end face of flange and the said first air channel end face distance on said first air channel.
Further, the connection structure in aforesaid railcar air channel also is provided with sealing band on the said first air channel end face.
The beneficial effect of the utility model is: the utility model is simple in structure, and fitting operation is simple and easy, has improved work efficiency; Vehicle maintenance when maintenance dismounting is quick and convenient, has solved to connect poorly sealed in the aluminum alloy air channel and an inconvenient difficult problem is installed.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Embodiment 1
The connection structure in a kind of railcar air channel that present embodiment provides; As shown in Figure 1; Comprise a pair of first flange 4, second flange 3 that is installed in respectively on first air channel 2 and second air channel 1, wherein first flange 4 on first air channel 2 is installed in the end face outside, said first air channel; Second flange 3 on second air channel 1 is installed in the inboard of the said second air channel end face; Second flange, 3 end faces on second air channel 1 and the said second air channel end face distance are less than or equal to first flange, 4 end faces and the said first air channel end face distance on said first air channel 2, on the first air channel end face, also are provided with sealing band 5.
The air channel of present embodiment is before connecting, and on the main body of air channel, sealing band 5 is attached to earlier on first air channel 2 simultaneously with rivet for first flange 4 and second flange, 3 difference elder generations; When mounted, second air channel 1 is plugged into 2 places, first air channel, establishes ethylene propylene diene rubber foaming sealing band 5 plays sealing and regulates in the centre effect therebetween; After pegging graft well; Each flange place get final product with fastener 6 is fixing, and wherein having only three faces for the rectangular aluminium alloy air channel is flanges, air channel top owing at the roof face; Do not add bolted so do not manage orchid, easy for installation like this.Operation order is opposite with assembling during dismounting.
Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (3)
1. the connection structure in railcar air channel comprises a pair of flange that is installed in respectively on first air channel and second air channel, it is characterized in that: wherein the flange on first air channel is installed in the end face outside, said first air channel; Flange on second air channel is installed in the inboard of the said second air channel end face.
2. the connection structure in railcar according to claim 1 air channel is characterized in that: end face of flange on said second air channel and the said second air channel end face distance are less than or equal to end face of flange and the said first air channel end face distance on said first air channel.
