Embodiment
In order to make object of the present invention, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, rotatable folding structure of the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Fig. 1,2,3,4,5, a kind of rotatable folding structure, comprises support tube 1, support 2, rotating disk 4 and base 9;
Support tube 1 and support 2 removably connect, and mutually can fold with support 2;
Support 2 is fixedly mounted on rotating disk 4;
Rotating disk 4 and base 9 removably connect, and can rotate relative to base 9.
When support tube 1 is opened relative to support 2, support tube 1 can be made perpendicular to base 9, this structure at this moment can be made to be in more stable state.Support 2 is fixedly mounted on rotating disk 4, when rotating disk 4 rotates relative to base 9, support 2 and support tube 1 can be driven to rotate, thus realize spinfunction, when rotating disk 4 is relative to base 9 reciprocating rotary, support 2 and support tube 1 do reciprocating rotary under the drive of rotating disk 4, thus realize the oscillating function of support tube 1.
More preferably, as a kind of embodiment of the present invention, support 2 departs from the center of rotating disk 4 with the link position of rotating disk 4.
Like this when rotating disk 4 rotates relative to base 9, when support tube 1 turns to the central position away from base 9 at link position, mutually folded by support tube 1 relative to the direction of the central position of base 9 and support 2, at this moment folding effective length is the longest.Because this increasing folding effective length.
More preferably, as another kind of embodiment of the present invention, support 2 is bolted on rotating disk 4.
Concrete mounting type is that the position of installing with support 2 on rotating disk 4 makes some interior threaded holes, on support 2, join holes drilled through simultaneously, mentioned here join bore be join brill with the some interior threaded holes on rotating disk 4, be tightened onto with the screw through hole passed on support 2 in the interior threaded hole on rotating disk 4 and go, thus support 2 is securely fixed on rotating disk 4, if need rotating disk 4 and support 2 to take apart, only screw need be unloaded down.Therefore installation and removal are convenient to.
More preferably, as another kind of embodiment of the present invention, rotating disk 4 departs from the center of base 9 with the link position of base 9.
The effective length that the more effective increase of such energy is folding.
More preferably, as another kind of embodiment of the present invention, twisted axis 3 is also comprised;
Support tube 1 is hinged on support 2 by twisted axis 3.
Support tube 1 can with twisted axis 3 for running shaft rotates, complete support tube 1 folding or opening relative to support 2, and support tube 1 can with twisted axis 3 for running shaft rotates, rotatable angular range is large, fully can meet vertical relative to base of support tube 1 when opening.
More preferably, as another kind of embodiment of the present invention, twisted axis 3 is bolt axis;
When support tube 1 is opened to the position of needs, is screwed support tube 1 and support 2 are closely fixed by nut and bolt axis, at this moment support tube 1 can not be that rotating shaft is done and rotated with bolt axis, and stability is guaranteed.When needing folding, unclamped by nut, at this moment support tube 1 can be again that rotating shaft is done and rotated with bolt axis.
This mode connects and ensure that stability, and operation is very easy.
More preferably, as another kind of embodiment of the present invention, bearing 6 is also comprised;
Rotating disk 4 is arranged running shaft (not shown);
Base 9 is arranged bearing support 11;
Running shaft is arranged in bearing support 11 by bearing 6, thus rotating disk 4 is rotated relative to base 9 by bearing 6.
The contact of such running shaft be the inner sleeve of bearing 6, what bearing support 11 contacted is the overcoat of bearing 6, the cooperation at two places is transition fit, therefore all there will not be relative movement between the inner sleeve of running shaft and bearing 6 and the overcoat of bearing support 11 and bearing 6, the frictional force rotating generation between running shaft and bearing support 11 only appears at bearing 6 itself.
This mode can make rotating disk 4 light more flexibly relative to the rotation of base 9, decreases fricative accessory loss simultaneously, extends working life.
More preferably, as another kind of embodiment of the present invention, also comprise drive motor 7 and the first drive portion 8;
Base 9 is arranged electric machine support 10;
Drive motor 7 is arranged on electric machine support 10;
Rotating disk is arranged the second drive portion 5;
Drive motor and the first drive portion are in transmission connection;
First drive portion 8 and the second drive portion 5 are in transmission connection, and drive rotating disk 4 to rotate for making drive motor.
What this mode adopted is that drive motor 7 drives rotation, instead of handmade rotary, has saved manpower, is run simultaneously and realizes rotating disk 4 relative to base 9 reciprocating rotary, thus realize the oscillating function of support tube 1 by the clockwise and anticlockwise of drive motor 7.
More preferably, as another kind of embodiment of the present invention, the first drive portion 8 and the second drive portion 5 are gear.
Adopt gear transmission to be a kind of typical mechanical drive mode, can space be saved, reduce noise.
More preferably, as another kind of embodiment of the present invention, base plate 12 is also comprised;
Base plate 12 is fixedly connected with base 9, for covering base 9.
The parts such as drive motor 7, bearing 6 and gear can be protected like this, avoid entering of dust, increase the service life.
A kind of electric fan, comprises the rotatable folding structure of above any embodiment.
The above embodiment only have expressed several mode of execution of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
