Abstract
The invention discloses an automobile air-conditioner pipeline joint flange connecting structure, which comprises a pipeline (1) and a flange (2), wherein the pipeline (1) and a connecting head are integrally formed, and the pipeline (1) passes through a circular hole (3) in the flange (2); the inner surface of the circular hole (3) is a toothed wall (4) provided with a plurality of protrusions, the pipeline (1) is riveted together with the toothed wall (4), the inner surface of the circular hole (3) is step-shaped, the toothed wall (4) is an inner surface with small diameter, and the protrusions on the toothed wall (4) are uniformly distributed on the inner surface; and an end forming rib (5) is arranged on the pipeline (1), and the end forming rib (5) is mutually matched with the inner surface with large diameter on the circular hole (3). The pipeline and the flange of the automobile air-conditioner pipeline joint flange connecting structure of the special structure are integrally formed and riveted on the inner side of the circular hole of the flange after being directly formed, and the inside surface of the circular hole of the flange is toothed and riveted with the pipeline to form gapless joint, so that the sealing property of the structure is increased.
Description
Technical field
The present invention relates to a kind of linkage structure, especially relate to a kind of car air conditioner pipe joint flanged connecting structure.
Background technique
Existing air-conditioning duct joint flange linkage structure be with pipeline directly and flange weld together, structure shown in Figure of description 1, the end of pipeline is welded on an end of flange, yet always there are phenomenons such as rosin joint or welding overdo in the weld of this kind Placement, have a strong impact on the sealability of air-conditioning duct, simultaneously, in the process of installing and fixing, because the defective that welding exists also influences the constant intensity of flange, and welding cost is higher, is unfavorable for the demand of actual use.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of car air conditioner pipe joint flanged connecting structure at problems of the prior art, its objective is to guarantee being connected firmly of linkage structure, good seal performance, good reliability.
Technological scheme of the present invention is that this kind car air conditioner pipe joint flanged connecting structure comprises pipeline and flange, described pipeline and connecting head are formed in one, described pipeline runs through the circular hole on the flange, the internal surface of described circular hole is the dentation wall that is provided with a plurality of projectioies, and pipeline and dentation wall are riveted together.
The internal surface of described circular hole is a stepped shaft, and the dentation wall is the less internal surface of its diameter, and the projection on the dentation wall is evenly distributed on the internal surface.
Described pipeline is provided with end moulding muscle, and the internal surface that diameter is bigger on end moulding muscle and the circular hole cooperatively interacts.
Described flange is provided with the mounting hole that is used for fixing.
A kind of car air conditioner pipe joint flanged connecting structure with above-mentioned special construction has the following advantages:
1. the pipeline and the connecting head of this kind car air conditioner pipe joint flanged connecting structure are one-body molded, are riveted on the inboard of flange circular hole behind the straight forming, and the surface of flange circular hole inboard is that the no gap of dentation and pipeline riveted joint back is adjacent to, and increases its sealing.
2. this kind car air conditioner pipe joint flanged connecting structure has increased the intensity that pipeline is connected with pressing plate, and the firm reliability of reinforced pipe terminal portion has good practicability.
3. this kind car air conditioner pipe joint flanged connecting structure adopts riveted way to replace existing welding manner, has reduced the pollution of environment, has improved operator's working environment, and simultaneously, processing cost also reduces significantly.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of existing Placement.
Fig. 2 is a linkage structure schematic representation of the present invention.
Fig. 3 is the structural representation of flange among the present invention.
In Fig. 1-3,1: pipeline; 2: flange; 3: circular hole; 4: the dentation wall; 5: end moulding muscle; 6: mounting hole.
Embodiment
By structure shown in Figure 1 as can be known, existing air-conditioning duct joint flange linkage structure be with pipeline directly and flange weld together, the end of pipeline is welded on an end of flange, yet always there are phenomenons such as rosin joint or welding overdo in the weld of this kind Placement, have a strong impact on the sealability of air-conditioning duct, simultaneously, in the process of installing and fixing, because the defective that welding exists also influences the constant intensity of flange, and welding cost is higher, is unfavorable for the demand of actual use.
By the combination of structure shown in Fig. 2-3 as can be known, this kind car air conditioner pipe joint flanged connecting structure comprises pipeline 1 and flange 2, pipeline 1 is one-body molded with connecting head, and pipeline 1 runs through the circular hole 3 on the flange 2, the internal surface of circular hole 3 is the dentation walls 4 that are provided with a plurality of projectioies, pipeline 1 is riveted together with dentation wall 4, the internal surface of circular hole 3 is a stepped shaft, dentation wall 4 is the less internal surface of its diameter, and the projection on the dentation wall 4 is evenly distributed on the internal surface, pipeline 1 is provided with end moulding muscle 5, and the internal surface that diameter is bigger on end moulding muscle 5 and the circular hole 3 cooperatively interacts, and flange 2 is provided with the mounting hole 6 that is used for fixing.Be riveted on the inboard of flange circular hole 3 behind pipeline 1 and the connecting head straight forming, the surface of flange circular hole 3 inboards is that the no gap of dentation and pipeline riveted joint back is adjacent to, increase its sealing, increased the intensity that pipeline is connected with pressing plate simultaneously, the firm reliability of reinforced pipe terminal portion has good practicability.
This kind car air conditioner pipe joint flanged connecting structure adopts riveted way to replace existing welding manner, has reduced the pollution of environment, has improved operator's working environment, and simultaneously, processing cost also reduces significantly.
