Abstract
The utility model discloses a blade structure of an axial flow fan. The connecting mode that compression is carried out through two Haff wheel hubs is mostly adopted by installation of blades of existing small and medium-sized axial flow fans, and the defects that time is wasted in the process of manufacturing and cost is high exist. According to the technical scheme, the blade structure of the axial flow fan is characterized in that a blade handle is a bolt, the bolt is embedded into a blade body when aluminum alloy low-pressure casting of the blade body is carried out, the head portion of the bolt is embedded into the blade body, and the tail portion of a threaded rod of the bolt is arranged on the outer side of the inner end of the blade body. The blade structure of the axial flow fan has the advantages of being simple in processing technology, convenient to install, low in cost and the like.
Description
Technical field
The utility model relates to the ventilator vitals, specifically a kind of axial-flow fan blade structure.
Background technique
Now, for the middle-size and small-size axial-flow fan blade of general ventilation system, because type is little, the centrifugal force less that self produces, only have several thousand newton usually, and other extraneous load is also little., while there is production costs in the Placement that the installation of current middle-size and small-size axial-flow fan blade mostly adopts two Hough wheel hubs to compress and the high defect of cost.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the in-problem defect of above-mentioned prior art, and a kind of simple in structure, low cost of manufacture, axial-flow fan blade structure easy to maintenance are provided.
For this reason, the utility model adopts following technological scheme: a kind of axial-flow fan blade structure, comprise blade and petiole, it is characterized in that, described petiole is embedded in the bolt on blade while being a blade employing aluminum alloy low-pressure casting, the head of described bolt is embedded in blade, and the screw rod tail of bolt is placed in the outside of blade the inner.
Further, the screw rod tail of described bolt is fixed on one by nut and hangs tight on the sidewall of formula wheel hub.
The utlity model has following beneficial effect: processing technology is simple, easy for installation, low cost of manufacture.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is stereogram of the present utility model.
Fig. 3-4 are arranged on the structural representation on the axial-flow blower wheel hub for the utility model.
Embodiment
Below in conjunction with specification drawings and specific embodiments, the utility model is described in further detail.
Axial-flow fan blade as shown in the figure, described blade is aluminum alloy low-pressure casting, it is comprised of blade 1 and petiole 2 two-part.Blade, when low-pressure die casting, is mounted to the hex head bolt of preprepared standard type Full Thread FT in die casting mould, and after moulding, hexagon bolt head is wrapped up by the aluminum casting profile material fully.During installation, regulate blade angle, the screw rod tail of its bolt is fixed on and hangs tight on formula wheel hub 4 by nut 3.Being arranged on the number of blade hung tight on formula wheel hub 4 is 4～10.
Claims (2)
1. an axial-flow fan blade structure, comprise blade (1) and petiole (2), it is characterized in that, described petiole (2) is embedded in the bolt on blade while being a blade employing aluminum alloy low-pressure casting, the head of described bolt is embedded in blade, and the screw rod tail of bolt is placed in the outside of blade the inner.
