Abstract
The utility model provides a butt joint structure for automobile air-conditioning pipelines. The butt joint structure comprises a flared end, an insertion end and a clamp spring, a joint end is radially flared to form the flared end, and the flared end is inserted into the insertion end. The inner diameter of the flared end is larger than the outer diameter of the insertion end. An annular clamp spring groove and three sealing rings are arranged on the outer surface of the insertion end. The clamp spring is a U-shaped clamp spring, the flared end is provided with four insertion holes for inserting the U-shaped clamp spring, and an opening of the clamp spring is inserted into the flared end and clamped on the clamp spring groove. Three limit projections are arranged on the outside of each side of the opening. The butt joint structure is firmly mounted and positioned and simply operated, and production cost is greatly reduced. Butt joint can be facilitated even if the space around the pipelines is small, and the pipelines can be reliably sealed.
Description
Technical field
The utility model belongs to car air conditioner field, relates to pipelines of automobile air conditioner, particularly a kind of docking structure for pipelines of automobile air conditioner.
Background technique
Society, people raise day by day to the attention degree of environmental protection, require to reduce product cost and manufacturing efficiency simultaneously.In automotive field field of air conditioning, the evaluation of pipe interface, leakage in air-conditioning system is also seemed to particularly important.In prior art, relate to pipeline joint and interface leakage in automotive air-conditioning system, pipeline joint generally all adopts screw thread docking.Screw thread docking mode causes jointing screw thread processing aspect too complicated, and installation also bothers time-consuming, is also subject to spatial constraints.Sometimes pipeline space is around too little, and during docking, fastened tools just cannot be used, and the sealing effect of docking is very poor.
Model utility content
The utility model provides a kind of docking structure for pipelines of automobile air conditioner, object be make air-conditioning duct docking structure not only simply but also reliable.
To achieve these goals, the technological scheme that the utility model is taked is:
The described docking structure for pipelines of automobile air conditioner, comprise that jump ring, pipe interface end radially extend out the flared end of formation, insert the insertion end of described flared end, the outer surface of described insertion end is provided with annular jump-ring slot, described jump ring inserts described flared end and is stuck in described jump-ring slot, is also provided with sealing configuration on described docking structure.
Described jump ring is U-shaped jump ring, and described flared end is provided with the jack for the open part insertion of described jump ring.
The outside of described open part is provided with spacing preiection.
Described sealing configuration is the seal ring that is located at the outer surface of described insertion end.
Adopt technique scheme, have the advantages such as the firm position of installation, simple to operate and cost of production reduce greatly.Even if pipeline space is around less, also can dock easily pipeline, and guarantee that sealing is reliable.

Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail, to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present utility model, technological scheme.
The utility model provides a kind of docking structure for pipelines of automobile air conditioner, comprises that interface end radially extends out insertion end 3 and the jump ring 1 of the flared end 2 of formation, insertion flared end 2.The internal diameter of flared end 2 is greater than the external diameter of insertion end 3.Insertion end 3 is provided with annular jump-ring slot 4 and three seals circle 5 at outer surface.Jump ring 1 is U-shaped jump ring, and flared end 2 is provided with four jacks 6 for the open part insertion of jump ring 1, and jump ring 1 inserts flared end 2 and is stuck in jump-ring slot 4.The open part of jump ring 1 is stuck on described jump-ring slot 4, in the outside of open part, is provided with spacing preiection 7, Yi Bian three.
During docking, insertion end 3 is inserted to flared end 2 and hold out against, jack 6 is alignd with jump-ring slot 4.Jump ring 1 is inserted through jack 6, and insertion portion is stuck in and on jump-ring slot 4, plays axial restraint effect.7 of the spacing preiections in insertion portion outside can prevent that jump ring 1 from deviating from.Three seals circle 5 can prevent that pipeline from leaking at joint, good sealing effect.
By reference to the accompanying drawings the utility model has been carried out to exemplary description above; obviously the concrete realization of the utility model is not subject to the restrictions described above; as long as the various improvement that adopted method design of the present utility model and technological scheme to carry out; or directly apply to other occasions without improvement, all in protection domain of the present utility model.
