Increase KF flanges, clip and seal assembly on the basis of existing air-conditioning duct, realize the quick connection between two air-conditioning ducts.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of train air conditioner refrigerating pipeline
Quick Connect Kit, for connecting two air-conditioning ducts, it is characterised in that：It is connected including two with the end of the air-conditioning duct
KF flanges, the clip for connecting two KF flanges and the seal assembly between two KF flanged ends faces.
Further, the seal assembly includes positioning sleeve and is arranged in the locating slot inwall boss of positioning sleeve to position
O-ring seals in groove.
Further, holding set is coaxially arranged with the positioning sleeve, the O-ring seals are located at locating slot and holding
Between set.
Further, the air-conditioning duct is connected by copper reducer pipe with KF flanges.
Further, the clip is chain clasp, and the structure of clip includes multiple chain links, the two neighboring chain link of connection
Connecting plate, screw rod and fastening handle, one end of the screw rod is hinged on the end of clip, the other end through being fixed on clip
The limited block of head end be connected with fastening handle.
Further, the stopper slot for accommodating KF flanged ends and seal assembly is provided with the chain link.
Advantageous effects of the present utility model are：Mechanical structure and seal member package assembly in the present apparatus is simple,
It is easy to use, the connection of refrigeration pipe is efficiently completed, the operation and maintenance of air-conditioning refrigeration system has been effectively ensured.
The utility model is described in detail below in conjunction with the accompanying drawings.

Embodiment
Referring to accompanying drawing 1, the utility model provides a kind of train air conditioner refrigerating Quick connector for pipeline, for connecting
Two air-conditioning ducts 3, including two KF flanges 1 connected with the end of above-mentioned air-conditioning duct 3, for being connected two KF flanges
1 clip and the seal assembly between two connecting end surfaces of KF flanges 1.
Referring to accompanying drawing 1 and 3, above-mentioned seal assembly includes positioning sleeve 2 and is arranged in the inwall boss of positioning sleeve 2 to position
O-ring seals 11 in groove 2-1.Holding set 10 is coaxially arranged with positioning sleeve 2 not prevent O-ring seals 11 excessively or not
Rational deformation, O-ring seals 11 are located at locating slot 2-1 and keep covering between 10.The width of set 10 is kept to be less than or equal to be formed
The width of locating slot 2-1 boss.Locating slot 2-1 is located at the middle part of the inwall of positioning sleeve 2, is located at locating slot 2-1 two in positioning sleeve 2
The inwall of side is used for the clamp connection end for positioning KF flanges 1.
Referring to accompanying drawing 1, the structure of KF flanges 1 includes pipeline connection end and clamp connection end.Above-mentioned air-conditioning duct 3 is borrowed
Copper reducer pipe 9 is helped to be connected with the pipeline connection end of KF flanges 1.The outer surface of wherein clamp connection end side is tapered or circular arc
Shape, when clip gradually compresses, the clamp connection end distance of two flanges reduces, and coordinates compression sealing ring to realize with boss close
Envelope.
Referring to attached Fig. 1 and 2, above-mentioned clip is chain clasp, and it is adjacent that the structure of clip includes multiple chain links 4, connection
Connecting plate 5, screw rod 6 and the fastening handle 7 of two chain links 4, one end of above-mentioned screw rod 6 are hinged on the end of clip, another
The limited block 8 through the head end for being fixed on clip is held to be connected with fastening handle 7.
The stopper slot 4-1 for accommodating two clamp connection ends of KF flanges 1 and seal assembly is equipped with each chain link 4, it is more
The annular space that individual stopper slot 4-1 is cooperatively formed forms the compression space to two clamp connection ends of KF flanges 1.
Attachment means of the present utility model are as follows using process：
Fastening handle 7 is unclamped first, and the space for forming multiple chain links 4 is put into clamp connection end and the sealing of flange
Component.Now start to tighten fastening handle 7 so that the space behavior that the clamp connection end of two flanges is formed between two carrier bars
