Background technology
The blade of large scale industry ceiling fan is generally wider, longer, gets into smooth root of blade for a long time namely blade is matched somebody with somebody with petiole
Close position to be easier to be acted on and be deformed, crack conditions by centrifugal force, so the comprehensive strength problem of root of blade seems special
It is important.With the development of large scale industry ceiling fan technology, each producer is also higher and higher to the attention rate of this problem, occurs on the market
Various fixed way blades, but the generations of the still unavoidable crack conditions of the blade of many producers.Through undue
Analysis, this phenomenon is more than caused by blade insufficient strength itself, even more since the combination of blade and petiole is improper
Caused by.
Utility model content
It is easier to be acted on by centrifugal force with petiole matching part for the blade of above-mentioned existing large scale industry ceiling fan and produces
The problems such as deformation, crack conditions, the utility model provide a kind of large scale industry ceiling fan plug-in type petiole.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of large scale industry ceiling fan plug-in type petiole, the petiole are processed and formed at one time or directly using high-strength material
Using forging molding of forging, which is cylindrical insertion end, and the other end is flat straight coupling, cylindrical insertion end
Annular protrusion is equipped between flat straight coupling, the thickness of the flat straight coupling is not less than the section half of cylindrical insertion end
Footpath, the width of flat straight coupling are more than the diameter of section of cylindrical insertion end, distinguish in cylindrical insertion end and flat straight coupling
Equipped with least two through holes.
It is consistent that arc gusset internal diameter is reserved in outside diameter and the matched somebody with somebody blade inner cavity of the cylinder insertion end, and blade and cylinder
The top and bottom of shape insertion end contact portion offer long slot bore and are used for fixing petiole and blade plug welding.
The annular protrusion be used for position petiole insertion blade depth, after blade angle is set, annular protrusion up and down with
Blade tip contact portion is fixed using welding manner.
The cross-sectional outer diameter of the annular protrusion and the equivalent width of flat bar straight coupling.
The beneficial effects of the utility model：
Large scale industry ceiling fan plug-in type petiole provided by the utility model, petiole one end are cylindrical insertion end, are used for
It is inserted into blade interior to fix with through the arched ribs of whole blade coordinating, can so ensures petiole and contact surface at blade cooperation
Product；Petiole other end thickness is not less than the flat bar straight coupling of the section radius of cylindrical insertion end, in the plane coordinated with wheel hub
Equipped with through hole at two, fixed for coordinating with the location hole on wheel hub；Annular protrusion for ring section section, the section of annular protrusion
The equivalent width of outside diameter and flat bar straight coupling, the insertion depth positioning of petiole when coordinating available for petiole blade.In addition, should
The fit system of petiole and blade further includes and strip hole is provided with the blade top and bottom of two parts crossover sites, and by leaf
The cylindrical surface of handle is exposed, most at last two parts respectively at the fluting of blade top and bottom and petiole and blade butt junction location disk
Place is fixed together using welding manner, and through hole at two is additionally provided with the cylinder coordinated with flabellum, for above and below flabellum two
Hole on face（The both ends of spreading bar are snapped in the pore size distribution in flabellum, are not intersected cooperation with weld seam and are fixed, further strengthen two
The cooperation intensity of parts；The utility model overall quality is light, and intensity is high, simple in structure, big with flabellum coordinate contact surfac product, outside
Portion's welding manner strengthens its overall construction intensity again.

Embodiment
The utility model is further elaborated with reference to embodiment.
As shown in the figure：A kind of large scale industry ceiling fan plug-in type petiole, the petiole using high-strength material time processing into
Type directly uses forging molding of forging, which is cylindrical insertion end 1, and the other end is flat straight coupling 3,
Annular protrusion 2 is equipped between cylindrical insertion end 1 and flat straight coupling 3, the thickness of the flat straight coupling 3 is not less than cylinder
The section radius of insertion end 1, the width of flat straight coupling 3 are more than the diameter of section of cylindrical insertion end 1.
In Fig. 1, petiole is processed and formed at one time through CNC numerically controlled lathes using high-strength aluminum alloy bar or using forging one
Secondary forging molding.
In Fig. 2 as it can be seen that petiole one end has the cylinder of certain length, for being inserted into blade interior and running through whole leaf
The arched ribs of piece, which coordinate, to be fixed, and can so ensure petiole and contact area at blade cooperation.Petiole center section is annular protrusion,
