CN2800032Y - Pipe and line connecting structure of air conditioner heating system for passenger car - Google Patents

Abstract

The utility model discloses a pipe line connecting structure of an air conditioner heating system for passenger cars. A rigid connecting lining core is separately sheathed on a joint point between two pipe lines which are butted with each other. Because the rigid connecting lining core is sheathed on the joint point between two pipe lines which are butted with each other and can consolidate the rigidity of the pipe line on the junction of the pipe lines, the pipe lines can not deform under the action of external force, such as a clamping hoop and the sealability of the junction of the pipe lines are better ensured. Thereby, the connection of pipe lines in air conditioner heating systems for passenger cars can adopt pipe lines with poor rigidity, lower price and lighter material, reducing the cost of pipe lines and the weight of the air conditioner heating system for the whole passenger car.

Description

The passenger vehicle pipeline linkage structure of warming by air conditioner system

Technical field

The utility model relates to a kind of pipeline linkage structure that two pipelines are linked together, and particularly relates to the pipeline linkage structure of a kind of passenger vehicle with the warming by air conditioner system.

Background technique

With in the warming by air conditioner system, need seal butt joint (as shown in Figure 1) at passenger vehicle between each pipeline, the sealing between when guaranteeing each pipeline 1 connection, the pipeline of commonly using all adopts aluminium or copper material.Pipeline cost height, weight that this aluminium or copper material are made are heavier.For this reason, people have selected the lighter aluminium-plastic composite pipe of material for use, but this aluminium-plastic composite pipe is in installation process, and when cutting off pipeline, incision position forms irregular present situation easily, the airtight quality when being difficult to guarantee to install.

The model utility content

The purpose of this utility model is to provide the pipeline linkage structure of a kind of with low cost, passenger vehicle that weight is lighter with the warming by air conditioner system.

For achieving the above object, technical solution of the present utility model is:

The utility model is the pipeline linkage structure of a kind of passenger vehicle with the warming by air conditioner system, is nested with a connection lining core with rigidity respectively at two pipe joint places of butt joint mutually.

One end of described connection lining core has the bulge loop that a circle extends radially outward.

Be provided with a circle around complete all flanges on the outer wall of described pipeline, this flange is near a connecting end of pipeline.

After adopting such scheme, because the utility model is nested with a connection lining core with rigidity respectively at the pipeline place of butt joint mutually, this connection lining core can be strengthened the pipeline rigidity of pipeline joint greatly, pipeline can be out of shape under the effect that is subjected to external force such as clip, guaranteed the sealing of pipeline joint preferably, thereby, in passenger vehicle connects with the pipeline of warming by air conditioner system, can adopt relatively poor but price is lower, material the is lighter pipeline (as: aluminium-plastic composite pipe) of rigidity, greatly reduce the cost of pipeline and whole passenger vehicle weight with the warming by air conditioner system.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Description of drawings

Fig. 1 is the pipeline connection diagram of passenger vehicle with the warming by air conditioner system;

Fig. 2 is the pipeline connection diagram of Fig. 1 at the A place;

Fig. 3 is the pipeline connection diagram of Fig. 1 at the B place.

Embodiment

As shown in Figure 2, the utility model is the pipeline linkage structure of a kind of passenger vehicle with the warming by air conditioner system, and this structure is the connection (Fig. 1 A place) that is used between the linear pipeline.This structure is to be nested with a connection lining core 2 with rigidity respectively in two pipeline 1 joints of butt joint mutually.One end of described connection lining core 2 has the bulge loop 21 that a circle extends radially outward, and when connecting lining core 2 insertion pipelines 1, this bulge loop 21 can limit and connect the degree of depth that lining core 2 inserts pipeline 1.

During installation, be equipped with the pipeline 1 insertion tube pipeline connector 3 in opposite directions that connects lining core 2, screw tight collar nut 31, extruding is installed in O-ring seal 4 and the snap ring 32 in the pipe joint 3, O-ring seal 4 and snap ring 32 stress deformations radially inwardly apply a clamping force, and two pipelines 1 are tightly connected.

Fig. 3 is pipeline the linkage structure (in Fig. 1 B place) linear pipeline and crooked pipeline between of passenger vehicle with the warming by air conditioner system.This structure is to be nested with a connection lining core 2A with rigidity respectively in two pipeline 1 joints of butt joint mutually.For preventing that pipeline 1 from coming off vertically, on the outer wall of described pipeline 1, be provided with a circle around complete all flanges 11, this flange 11 is arranged on the connecting end 12 near pipeline 1.

During installation, the pipeline 1 that is equipped with connection lining core 2A inserts in opposite directions and connects sebific duct 3A, and cover front band 4A screws clip 4A, and clip 4A inwardly pushes and connects sebific duct 3A, and connection sebific duct 3A is fitted tightly on pipeline 1, and two pipelines 1 are tightly connected.

Pipeline of the present utility model can be selected light, the easy bending of material for use, be difficult for aging pipeline, as: aluminium-plastic composite pipe etc.

Claims (3)

1, a kind of passenger vehicle is characterized in that: be nested with a connection lining core with rigidity respectively at two pipe joint places of butt joint mutually with the pipeline linkage structure of warming by air conditioner system.

2, the passenger vehicle according to claim 1 pipeline linkage structure of warming by air conditioner system is characterized in that: an end of described connection lining core has the bulge loop that a circle extends radially outward.

3, passenger vehicle according to claim 1 is characterized in that: be provided with a circle around complete all flanges on the outer wall of described pipeline, a connecting end of the close pipeline of this flange with the pipeline linkage structure of warming by air conditioner system.
