Type does not influence to demould.Floor replaces collocation mode while strengthening the structural strength of pipe fitting root with groove, reduces material
Needed for material, overall weight is reduced, while the finite thickness of single floor, reduce the shrinkage cavity defect in manufacturing process can
Can, promote product quality.
As a further improvement of the present invention, the quantity of floor is odd number.
Beneficial effect by adopting the above technical scheme is: floor is odd number, compared to the floor of even number, structure in all directions
Intensity is relatively uniform, is less prone to the phenomenon of periodic structural strength unevenness.
As a further improvement of the present invention, the junction radical length of floor and diskware is less than the company of floor and pipe fitting
Connect the axial length at place.
Beneficial effect by adopting the above technical scheme is: guaranteeing that the axial length of floor is relatively long, to same axial long
It spends longer pipe fitting and plays the role of good structural strengthening.
As further improvement of the invention, floor is connected by inclined-plane with pipe fitting in one end away from diskware, inclined-plane
It is gradually short along the direction away from pipe fitting own axes with the axial length of pipe fitting own axes angle at an acute angle, floor.
Beneficial effect by adopting the above technical scheme is: inclined-plane make floor top and root gradually transition, using compared with
Few material increases the structural strength of floor, more preferable to the support effect of pipe fitting.
As further improvement of the invention, floor is circumferential surface, the week of several floors in one end away from pipe fitting
The same space periphery is coincided with to face.
Beneficial effect by adopting the above technical scheme is: circumferential surface moulding is by the cylindrical shape of one convenient for floor, groove
Thick wall processing, simple process.
As further improvement of the invention, the inner corner trim junction of floor and pipe fitting, diskware is provided with filleted corner, floor
Itself external corner side has bull nose.
Beneficial effect by adopting the above technical scheme is: filleted corner avoids stress raiser, prevents air conditioning for automobiles from compressing
Machine front cover is broken in use.Bull nose makes floor be not easy to collide with and generate gap.
As further improvement of the invention, the intersection of pipe fitting and diskware has annular groove, the recess side of annular groove
To parallel with the own axes direction of pipe fitting, floor is contacted with annular groove, floor along pipe fitting radially be shorter in length than annular groove
Along the length radially of pipe fitting.
