Abstract
The utility model discloses a double -deck horn mouth air conditioner connecting pipe, including joint, connecting pipe, fastening nut, connecting pipe and joint set gradually in fastening nut, and the connecting pipe that is located fastening nut is provided with outwards convex tubaeform outer edge, fastening nut with connect be provided with respectively with tubaeform outer inclined plane along the laminating, it is tubaeform outer along including outside convex flaring portion, tubaeform outer is connected and to the turn -ups portion of enstrophe book with flaring portion along still including, turn -ups portion and flaring portion are hugged closely. The utility model has the advantages that: wireless connection is good, can not take place to leak.
Description
Technical field
The utility model relates to a kind of joint, and more particularly, it relates to a kind of double-deck horn mouth air conditioner connecting pipe.
Background technique
Double-deck horn mouth air conditioner connecting pipe can realize the quick connection of air-conditioning duct, easy to use, fast, laborsaving, the double-deck horn mouth air conditioner connecting pipe of existing one on market, comprise copper sleeve, connecting tube, copper nut, described connecting tube inserts in copper nut, and the connecting tube being arranged in copper nut is provided with outwardly tubaeform outer, during use, tubaeform outer extrudes and is close to by copper sleeve and copper nut, complete the connection of pipeline, but after Long-Time Service, perfect plasticity distortion in tubaeform outer after the long-term pressurized in tubaeform outer, the vibrations of air conditioner, horn mouth local is made to have loosening, make copper sleeve and connecting tube, micro-gap is produced between copper nut, easy leakage, have a strong impact on the normal use of air-conditioning duct.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of good connecting effect, and the double-deck horn mouth air conditioner connecting pipe leaked not easily occurs.
For achieving the above object, the utility model provides following technological scheme: a kind of double-deck horn mouth air conditioner connecting pipe, comprise joint, connecting tube, tightening nut, described connecting tube and joint are successively set in tightening nut, the connecting tube being positioned at tightening nut is provided with outwardly tubaeform outer, described tightening nut and joint are respectively arranged with the inclined-plane of fitting with tubaeform outer, described tubaeform outer comprises outwardly expansion mouth, described tubaeform outer also comprises and being connected and the turn-up portion of fold inward with expansion mouth, described turn-up portion and expansion mouth are close to.
Preferably, described turn-up portion length is less than expansion mouth length.
Preferably, described expansion mouth is consistent with turn-up portion angle of inclination.
Preferably, described expansion mouth and turn-up portion are wholely set.
By adopting technique scheme, expansion mouth and turn-up portion are arranged in flaring outer, flaring outer is made to have larger deformability, when double-deck horn mouth air conditioner connecting pipe uses, connecting tube is inserted in tightening nut, and then joint is screwed in tightening nut, tubaeform outer is extruded by joint and tightening nut be respectively close to, make tubaeform outer that deformation occur, gap between joint and tightening nut is full of completely, prevent from joint from producing to leak, when there is micro-displacement generation by gap between joint and copper nut, because tubaeform outer has stronger deformation power, the gap produced directly is filled, prevent from joint from producing to leak.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the explosive view of the utility model embodiment;
Fig. 2 is the sectional view of the utility model embodiment.
Reference character: 1, joint, 2, connecting tube, 3, tightening nut, 4, tubaeform outer, 5, turn-up portion.
Embodiment
With reference to accompanying drawing, the utility model embodiment is described further.
As shown in Figure 1, a kind of double-deck horn mouth air conditioner connecting pipe 2, comprise joint 1, connecting tube 2, tightening nut 3, described connecting tube 2 is successively set in tightening nut 3 with joint 1, the connecting tube 2 being positioned at tightening nut 3 is provided with outwardly tubaeform outer 4, described tightening nut 3 and joint 1 are respectively arranged with the inclined-plane of fitting with tubaeform outer 4, described tubaeform outer 4 comprises outwardly expansion mouth, described tubaeform outer 4 also comprises and being connected and the turn-up portion 5 of fold inward with expansion mouth, described turn-up portion 5 is close to expansion mouth, flaring outer is arranged to expansion mouth and turn-up portion 5, flaring outer is made to have larger deformability, when double-deck horn mouth air conditioner connecting pipe 2 uses, connecting tube 2 is inserted in tightening nut 3, and then joint 1 is screwed in tightening nut 3, tubaeform outer 4 is extruded by joint 1 and tightening nut 3 be respectively close to, make tubaeform outer 4 that deformation occur, gap between joint 1 and tightening nut 3 is full of completely, prevent from joint from producing to leak, micro-displacement is there is when producing gap between joint 1 and copper nut, because tubaeform outer 4 has stronger deformation power, the gap produced directly is filled, prevent from joint from producing to leak.
Described turn-up portion 5 length is less than expansion mouth length, prevents from making connecting tube 2 less at the bore at this place when turn-up portion 5 is longer, is unfavorable for the cooling of air-conditioning.
Described expansion mouth is consistent with turn-up portion 5 angle of inclination, and it is large that tilt angle unanimously makes the two be extruded rear reaction force, and the gap of joint is extruded is full of completely, avoids leakage.
Described expansion mouth and turn-up portion 5 are wholely set, and are wholely set easily manufactured, can be integrally manufactured, just need not can use, save cost of production through welding.
Arc surface can be arranged in the joint of expansion mouth and turn-up portion 5, and during installation, arc surface can avoid operator to be scratched.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
