Description
1, technical field:
The utility model relates to the fan blade device that a kind of electric fan is used, and belongs to the renovation technique of the used fan blade device of electric fan.
2, background technique:
The existing used fan blade device of electric fan is the structure that adopts fan blade and stipule to rivet together, or adopts the structure of fan blade and the disposable injection molded of stipule.For example China Patent No. is that the fan blade described in 03274201 " fan blade that a kind of electric fan is used " is exactly to adopt the structure that is connected by the riveted joint mode with stipule, the Placement of this kind fan blade and stipule is under the few situation of blade quantity, as 3 fan blades, can realize being connected of fan blade and stipule.But at the multi-disc fan blade, as 5 fan blades when above, because the spacing of stipule is uncontrollable, stamping process is difficult to realize, so can't realize being connected of fan blade and stipule.And the blade structure of injection molded only is applicable to plastic blade.
3, summary of the invention:
The purpose of this utility model is to overcome above-mentioned shortcoming and provides a kind of dynamic balancing stable, the fan blade device that the electric fan that suitable varying number blade is used in combination is used.
Structural representation of the present utility model as shown in Figure 1, comprise blade (1) and stipule, wherein stipule includes stipule (2) and reaches stipule (3) down, the connecting end of blade (1) places between stipule (2) and the following stipule (3), and makes it to be solidly installed by the link (4) that passes down stipule (3), blade (1), last stipule (2).
Above-mentioned link (4) is a screw, or is rivet, or is pin.
The above-mentioned stipule (2) of going up is provided with the screw post (2A) of making screw, the connecting end of blade (1) is provided with connecting through hole (1A), following stipule (3) is provided with attachment post hole (3A), link (4) is a screw, link (4) passes down attachment post hole (3A) on the stipule (3) and the connecting through hole (1A) on the blade (1) successively, and twists solid in the screw of the set screw post of last stipule (2) (2A).
The utility model reaches stipule down because employing includes stipule, the connecting end of blade places between stipule and the following stipule, and by passing down stipule, blade, going up the structure that the link of stipule makes it to be solidly installed, therefore, not only dynamic balancing is stable for it, and the blade of suitable varying number is used in combination.The utility model is simple in structure, and assembling is the fan blade device that a kind of convenient and practical electric fan is used easily.
4, description of drawings:
Fig. 1 is STRUCTURE DECOMPOSITION figure of the present utility model.
5, embodiment:
Embodiment:
Structural representation of the present utility model as shown in Figure 1, comprise blade 1 and stipule, wherein stipule includes stipule 2 and following stipule 3, and the connecting end of blade 1 places between stipule 2 and the following stipule 3, and makes it to be solidly installed by the link 4 that passes down stipule 3, blade 1, last stipule 2.
Above-mentioned link 4 is a screw, or is rivet, or is pin.In the present embodiment, be convenient mounting or dismounting, link 4 is a screw, the above-mentioned stipule 2 of going up is provided with the screw post 2A that makes screw, the connecting end of blade 1 is provided with connecting through hole 1A, following stipule 3 is provided with attachment post hole 3A, and link 4 passes down attachment post hole 3A on the stipule 3 and the connecting through hole 1A on the blade 1 successively, and twists solid in the screw of last stipule 2 set screw post 2A.
