Abstract
The utility model provides a middle segment piece of a cross flow wind wheel. The cross flow wind wheel is formed by connecting a plurality of middle segment pieces, wherein each middle segment piece comprises a ring-shaped middle plate and a plurality of blades; the blades comprise fixed ends and free ends; the fixed ends of the blades are connected with the top surface of the middle plate; the free ends of the blades are welded with the bottom surface of another middle segment piece through ultrasonic waves; open slots are formed at the free ends of the blades of the middle segment piece; a plurality of blade slots are formed on the bottom surface of the middle plate correspondingly to the free ends of the blades; convex aggregate is arranged in the blade slots correspondingly to the open slots; the open slots are V-shaped, U-shaped or saw-tooth-shaped; and the convex aggregate is V-shaped, U-shaped or saw-tooth-shaped in a manner of being matched with the open slots. The open slots are formed at the end parts of the blades of the middle segment pieces of the cross flow wind wheel and the convex aggregate is arranged in the blade slots, so that even if a product is deformed to a certain degree, the blades and the blade slots of the product can be matched accurately through the guiding function of the convex aggregate. The middle segment piece has a simple and reasonable structure and is connected firmly and accurately.
Description
Technical field
The utility model relates to the middle joint spare of a kind of tubular wine wheel, particularly a kind of tubular wine wheel.
Background technique
Our company discloses the middle joint of the axial-flow fan of plate in a kind of improve at Chinese patent literature CN201354759 and on December 2nd, 2009, the middle joint of this structure the phenomenon that blade tip is out of shape occurs after depositing a period of time easily, cause blade tip be difficult to insert in the leaf groove of plate, it installs difficulty, haves much room for improvement.
The model utility content
The purpose of this utility model aims to provide a kind of simple and reasonable, not yielding or amount of deformation is less, play the effect of guiding, the middle joint spare of tubular wine wheel accurately that is connected firmly when cooperating between the joint part in two, to overcome deficiency of the prior art.
Press the middle joint spare of a kind of tubular wine wheel of this purpose design, described tubular wine wheel is connected and composed by joint parts in a plurality of, and middle joint spare comprises plate and some blades in the annular; Blade comprises fixed end and free end, and its fixed end is connected with middle plate top surface, free end and in another the joint part the underrun ultrasonic welding; Its structure characteristic is that the free end of blade is provided with opening slot, and the free end of the corresponding blade in middle plate bottom surface is provided with several leaf grooves, and corresponding described opening slot is provided with protruding aggregate in the leaf groove.
Described opening slot is V-shaped, U-shaped or zigzag fashion; The projection aggregate is V-arrangement, U-shaped or the zigzag fashion of mating with opening slot.
The top of described protruding aggregate extend out to outside the leaf groove, and each protruding aggregate connects into a ring-type from beginning to end.
Described leaf grooved ring shape is distributed on middle plate bottom surface, the leaf groove and with this in the blade of plate top surface stagger.
Described leaf slot cross-section is trapezoidal, and its bottom surface is narrow, and opening is wide, can make things convenient for the free end of blade to insert in the leaf groove, and when blade and middle plate during by ultrasonic welding, melten gel can be filled up gap between leaf groove and the blade automatically, makes both connections more firm.
Curved or the lineal shape in the cross section of described blade.
The blade tip of joint part is provided with in opening slot and the leaf groove and is provided with protruding aggregate in the tubular wine wheel of the present utility model, even if product has certain deformation, can the product blade be cooperated accurately with the leaf groove by the leading role of this protruding aggregate.It is simple and reasonable, be connected firmly accurately.
