The power line unwinding and winding mechanism of electric fan
Technical field
The utility model relates to electric fan, particularly a kind of power line unwinding and winding mechanism of electric fan.
Background technique
The power line unwinding and winding mechanism of the electric fan of Chu Xianing just uses on cylindrical fan to some extent in the market, concrete structure is that power line is wrapped in the effect of playing folding and unfolding in the base, though power line can folding and unfolding in base, just can wind the line and unwrapping wire but will pick up electric fan during operation, very inconvenient.Particularly pedestal fan normally hangs over power line or be wrapped on the head, and is very dangerous and not attractive in appearance.
The model utility content
The purpose of this utility model is to provide a kind of power line unwinding and winding mechanism of simple in structure, easy to use, electric fan that fabricating cost is low, safe and attractive in appearance.
The technological scheme that realizes the utility model purpose is: the utility model comprises fan body, upper and lower part at fan body is provided with the hanging wire button respectively, the hanging wire button opening on top upwards, Open Side Down for the hanging wire button of bottom, it is characterized in that described hanging wire is smashed has at least one can locate with being connected to of fan body and to be rotationally connected to change its opening direction.
In the technique scheme, be positioned at being connected to locate and being rotationally connected of the hanging wire button on fan body top and fan body.
Located for the rotation connection structure of above-mentioned hanging wire button and fan body is that circular groove is set on fan body, be provided with the central screw post in the circular groove, the upper and lower side of central screw post is respectively equipped with hemisphere engagement recess, be provided with cylindrical bore in the hanging wire button, be placed with the spring and the steel ball that are used for rotation positioning in the endoporus successively, the hanging wire button is installed in the circular groove on the fan body by screw, and steel ball places engagement in the hemisphere engagement recess in the groove.
In order not influence the controlling with attractive in appearance of electric fan, described hanging wire button is arranged on the back side of fan body.
The beneficial effects of the utility model are, owing to be provided with the opposing hanging wire button of opening respectively in the upper and lower part of fan body, and hanging wire smashs and have at least one can locate with being connected to of fan body and to be rotationally connected, to change its opening direction.Therefore, power line can be buckled to realize taking in of power line around upper and lower hanging wire easily; When need decontroling power line, only need hanging wire button with top rotate to that Open Side Down, can easily power line be buckled relieving from hanging wire.Compare with original power line hanging wire structure have simple in structure, rotate reliable, fabricating cost is low, safety coefficient is high, both artistic and practical, behaviour does easy characteristics.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
As Fig. 1, Fig. 2, shown in Figure 3, the utility model the utility model comprises fan body 1, upper and lower part at fan body 1 back side is provided with hanging wire button 4 respectively, hanging wire button 4 openings on top upwards, Open Side Down and fixing for the hanging wire button 4 of bottom, and being connected to locate of the hanging wire button 4 on described top and fan body 1 is rotationally connected to change its opening direction.
The hanging wire button 4 on top with located for the rotation connection structure of fan body 1 is: circular groove 11 is set on fan body 1, be provided with central screw post 13 in the circular groove 11, the upper and lower side of central screw post 13 is respectively equipped with hemisphere engagement recess 12, be provided with cylindrical bore in the hanging wire button 4 on top, be placed with the spring 3 and the steel ball 2 that are used for rotation positioning in the endoporus successively, hanging wire button 4 is installed in the circular groove 11 on the fan body 1 by screw 5, and steel ball 2 places engagement in the hemispheres engagement recess 12 in the groove 11.
During the utility model work, the spring 3 that is contained in hanging wire button 4 inside presses steel ball 2 does the engagement location with hemisphere mesh groove 12, and the while can be pulled hanging wire button 4 and be done 180 degree rotations to the left or to the right, and hanging wire button 4 opening directions upwards and are downwards being changed.
In addition, the hanging wire button 4 of fan body 1 bottom is enclosed within on the fixing column 14 by the cylindrical bore in it, and opening direction is fixed down and by screw 5, can not rotate.
During the utility model uses, when needs are taken in power line, the hanging wire button 4 on top is rotated to the location positioning that opening makes progress, then power line is got final product on upper and lower hanging wire button 4; When needs are decontroled power line, only need the hanging wire button 4 on top is rotated to the location positioning that Open Side Down, power line can be decontroled easily.It is very convenient to operate.
