And, pillar 2 uprightly to be installed on the pedestal 1, pillar base portion 5 need be inserted in the mounting hole 6, install the nut of the fixedly usefulness of expressing the figure at outstanding pillar base portion 5 from the below of bottom part 110, thus, pillar base portion 5 can be fixed on the bottom part 110, thereby pillar 2 relative pedestals 1 are uprightly installed.
Like this, the structure of the pedestal 1 of example 1 was so in the past, and user mode can be seen from the sectional drawing of Figure 14: bottom part 110 be hidden in upper component 100 below, only contact with 1 component in the upper component 100.
Therefore, this with precedent 1 in, in order to improve the market competitiveness of electric fan, even attempt to expand to the multi-colour direction, also can only adopt the color of the color that makes pillar 2 and pedestal 1 to become with a kind of color or make pillar 2 become green pedestal 1 becomes light green-these 2 kinds of schemes.And, when using these 2 kinds of colors, as if making pillar 2 become green, making pedestal 1 become red diverse like this color, such problem that is false in the design just appears.
Then, other example such as Figure 15 and shown in Figure 16.Figure 15 is another overall appearance figure of example in the past of electric fan, and Figure 16 is the exploded perspective view of electric fan pedestal circumference shown in Figure 15.On these figure and the example in the past 1 put down in writing of aforementioned Figure 12～Figure 14 have the same or corresponding prosign that used in the localities.And, should example in this narration call as example 2 in the past.
Electric fan of the electric fan of example 2 and aforementioned example in the past 1 was same in the past for this, was made up of pedestal 1, pillar 2, sliding tube (not expression among the figure), neck (not expression among the figure) and institute of electric fan portion (not expression among the figure).Different with the electric fan of aforementioned example in the past 1 is, is the formation of the pillar base portion of the formation of pedestal 1 and pillar 2.And, the 70th, this is the footing of a pillar portion of example 2 in the past.
Footing of a pillar portion 70 is the inverted simplification ship type shapes that will open below.And on this open underneath face, base floor 71 fixes helical rotation.Among Figure 16,73 are arranged on the tapped hole of the screw fixed of many places, and the 74th, the fixing screw that rotates usefulness.And, below base floor 71 on, formed the fixedly large diameter ring-type of usefulness of pillar, and formed screw section 72 outside for the fixedly usefulness of thread groove.
When the installation of pillar 2, in the open underneath portion fit on base floor 71 of pillar base portion 70, the pillar base portion 70 with pillar 2 under this state is embedded into depressed part 83.Thus, fixedly the screw section 72 of usefulness just by through hole 85 give prominence to below.Then, the nut 87 of fixing usefulness is screwed on the screw section 72 of fixing usefulness.Like this, pillar 2 just has been fixed on the pedestal 1.
, therefore the same as the example in the past 2 of this structure with aforementioned example in the past 1 because pedestal 1 also is integrated, in the time of consider color for the competitive ability that improves electric fan market aspect, also can only adopt these two types in the color of the color of pillar 2 and pedestal 1.
As routine in the past structure explanation finding about above representative, on electric fan in the past, because it is one in appearance that pedestal 1 looks, or be exactly in fact integrated molding, that just can not increase the variation of color, therefore, it is difficult trying hard to make electric fan to expand to the colorize direction.
