Abstract
The utility model relates to a leaf blade installing structure for a novel axial flow blower. Both a blade handle and a positioning groove are designed to be conical, the upper part of the blade handle is small, the lower part of the blade handle is large, the outer part of the positioning groove is small, and the inner part of the positioning groove is large; when in installation, the blade handle is arranged in the positioning groove, and upper and lower wheel hubs are screwed up and fixed by bolts after the angle of a leaf blade is well adjusted. By adopting the above structure, the installing and fastening area is increased, the firmness of an impeller is enhanced, the processing technique is simple, the installation is simple as well as convenient, the service life is long, the angleof the impeller can be adjusted at any time according to needs, and the using is convenient. The leaf blade installing structure has the characteristics of simple structure, convenient assembling as well as disassembling, firm installation, low cost, long service life and the like.
Description
Technical field
The utility model relates to a kind of blade installation structure of ventilation equipment, especially a kind of novel axial-flow fan blade mounting structure.
Background technique
The impeller blade mounting structure kind of axial-flow blower is a lot, from rivet arrangement, welded structure to integral die-cast structure etc., the blade installation structure technology of axial-flow blower has been improved much at present, its blade installation efficient also improves greatly, kind is also more and more, there are the shortcoming that the blade installation location is inaccurate and fan performance can not be regulated in existing blade rivet structure and blade welded structure, and a kind of specification can not realize utilizing the problem that angle is regulated the size of fan delivery and blast of adjusting.
Summary of the invention
The blade installation structure that is used for axial-flow blower that the purpose of this utility model is a kind of simple in structure, accurate positioning of design, the manufacturing maintenance cost is low.The technical solution of the utility model is so to realize:
Novel axial-flow fan blade mounting structure comprises the petiole (2) of blade (1) and below thereof, is located at the some locating slots (4) on the wheel hub (3), and described petiole (2) is up-small and down-big taper shape, locating slot (4) be outer little in big taper shape.
The impeller installing of the utility model design all is designed to taper shape with petiole (2) and locating slot (4), petiole (2) is up-small and down-big taper shape, locating slot (4) is outer little interior big taper shape, during installation petiole (2) is placed in the locating slot (4), after adjusting the angle of blade (1), will go up lower hub (3) again and tighten fixing with bolt.This structure makes installs fastening area and increases, and has strengthened the impeller fastness, and processing technology is simple, simple installation, and long service life, and can adjust the angle of impeller at any time as required, easy to use.The utlity model has simple in structure, easy accessibility, characteristics such as installation is fastening, cost is low, long service life.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model blade and petiole;
Accompanying drawing 2 is structural representations of the utility model wheel hub.
Embodiment
Below in conjunction with accompanying drawing,, the technical solution of the utility model is described in further detail by embodiment.
Embodiment: with reference to the accompanying drawings 1, accompanying drawing 2, novel axial-flow fan blade mounting structure comprises the petiole (2) of blade (1) and below thereof, is located at the some locating slots (4) on the wheel hub (3), described petiole (2) is up-small and down-big taper shape, and locating slot (4) is outer little interior big taper shape.
During installation, earlier conical petiole (2) is placed in the conical locating slot (4) during installation, adjust the angle of each blade (1) then after, will go up lower hub (3) again and tighten fixing with bolt.
Claims (1)
1, novel axial-flow fan blade mounting structure, the petiole (2) that comprises blade (1) and below thereof, be located at the some locating slots (4) on the wheel hub (3), it is characterized in that described petiole (2) is up-small and down-big taper shape, locating slot (4) is outer little interior big taper shape.
