Abstract
The utility model discloses a vehicle air conditioner system pipeline bell and plain end joint head belongs to automobile air -conditioning part technical field. Current bell and plain end joint head need be connected with the tubular metal resonator through the welding, and is hard when using the installation fee. The utility model relates to a connecting plate is equipped with many the axial notchs that circumference was evenly arranged on the pore wall of the circular through -hole of connecting plate, during the use, the tubular metal resonator adopts the internal expanding chuck to carry out the tensioning in inserting the circular through -hole of connecting plate, and the tubular metal resonator is under the effect of tensile force for the deformation is outwards expanded to the outer wall of tubular metal resonator, the outer wall of the tubular metal resonator after the deformation closely paste lean on in the pore wall of the circular through -hole of connecting plate, wherein, the outer wall of partial tubular metal resonator warp the back embedding in the axial notch of connecting plate, increase the friction surface between tubular metal resonator and the connecting plate, make the tubular metal resonator firmly in the connecting plate. The utility model discloses an in the axial notch of the tubular metal resonator outer wall embedding connecting plate after the internal expanding chuck will warp, avoided welding the trouble of bringing, and used simple to operate, reduced manufacturing cost.
Description
Technical field
The utility model belongs to car air conditioner component technology field, especially relevant with a kind of automotive air conditioning system pipeline plain adapter.
Background technique
In automotive air-conditioning system, to be interfixed support and connection by plain adapter between metal tube and metal tube, as shown in Figure 1, existing plain adapter comprises the connecting plate 5 and connecting head 4 that are connected as a single entity, one end of connecting plate 5 is provided with manhole 3, the other end is provided with U-shaped open recess 1, connecting head 4 is fixed on connecting plate 5 by manhole 3, the two ends of connecting head 4 are by being welded to connect metal tube, the U-shaped open recess 1 of connecting plate 5 is installed with metal tube, plain adapter is fixed by the mounting hole 2 that connecting plate 4 is offered, this integrated type plain adapter compares consumptive material, and need between connecting head with metal tube to be connected by welding manner, weld and comparatively bother, using to install comparatively wastes time and energy, the corresponding cost of production adding automotive air-conditioning system.
Model utility content
The purpose of this utility model is intended to overcome existing plain adapter and need be connected with metal tube by welding, uses the defect of installing and wasting time and energy, provides a kind of automotive air conditioning system pipeline plain adapter of exempting to weld.
For this reason, the utility model is by the following technical solutions: automotive air conditioning system pipeline plain adapter, it is characterized in that, described plain adapter is a plate, the hole wall of the manhole of connecting plate is provided with many axial notches of the even arrangement of circumference, during use, metal tube inserts in the manhole of connecting plate, internal expanding chuck is adopted to carry out tensioning, metal tube is under the effect of tension force, the outer wall of metal tube is made to expand outwardly distortion, the outer wall of the metal tube after distortion is closely posted by the hole wall of described connecting plate manhole, wherein, embed in the axial notch of described connecting plate after the outer wall distortion of part metals pipe, increase the rubbing surface between metal tube and connecting plate, metal tube is made to be secured in connecting plate.
The utility model can reach following beneficial effect: arrange axial notch by the manhole hole wall at connecting plate, by internal expanding chuck, the metal tube be plugged in manhole is carried out tensioning, make metal tube deformable filler in the axial notch of connecting plate, increase the rubbing surface between metal tube and connecting plate, metal tube is made to stablize the connecting plate be secured in as plain adapter, easy to install and use, avoid the trouble of welding and bringing simultaneously, save material, cost of production is reduced, thus reduces the cost of production of whole automotive air-conditioning system.
