Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with drawings and Examples pair
The rotatable folding structure of the present invention is further elaborated.It should be appreciated that specific embodiment described herein is only used
To explain the present invention, it is not intended to limit the present invention.
As shown in Fig. 1,2,3,4,5, a kind of rotatable folding structure, including support tube 1, support 2, rotating disk 4 and base 9；
Support tube 1 is detachably connected with support 2, and can mutually be folded with support 2；
Support 2 is fixedly mounted on rotating disk 4；
Rotating disk 4 is detachably connected with base 9, and can be rotated relative to base 9.
When support tube 1 is opened relative to support 2, support tube 1 can be made at this moment to make this structure place perpendicular to base 9
In more stable state.Support 2 is fixedly mounted on rotating disk 4, when rotating disk 4 rotates relative to base 9, can drive support 2
And support tube 1 rotates, so as to realize spinfunction, when rotating disk 4 is relative to 9 reciprocating rotary of base, support 2 and support tube 1 exist
Reciprocating rotary is done under the drive of rotating disk 4, so as to realize the oscillating function of support tube 1.
More preferably, a kind of embodiment as the present invention, the link position of support 2 and rotating disk 4 deviate in rotating disk 4
The heart.
So when rotating disk 4 rotates relative to base 9, when support tube 1 turns to the center away from base 9 in link position
During position, support tube 1 is mutually folded relative to the direction of the center of base 9 with support 2, the effective length at this moment folded
It is most long.Therefore the effective length of folding is added.
More preferably, another embodiment as the present invention, support 2 are bolted on rotating disk 4.
Specific mounting means makes some internal thread holes for the position installed on rotating disk 4 with support 2, while in support 2
Above match somebody with somebody holes drilled through, brill mentioned here of matching somebody with somebody is to pass through leading on support 2 with screw with boring with some internal thread holes on rotating disk 4
Hole is tightened onto in the internal thread hole on rotating disk 4, so as to which support 2 is securely fixed on rotating disk 4, if desired by rotating disk
4 take apart with support 2, need to only unload screw down.Therefore it is easily installed and dismantles.
More preferably, another embodiment as the present invention, the link position of rotating disk 4 and base 9 deviate base 9
Center.
It so can more effectively increase the effective length of folding.
More preferably, another embodiment as the present invention, in addition to twisted axis 3；
Support tube 1 is hinged on support 2 by twisted axis 3.
Support tube 1 can be rotated with twisted axis 3 for rotary shaft, completed support tube 1 relative to the folding of support 2 or beaten
Open, and support tube 1 can be rotated with twisted axis 3 for rotary shaft, and rotatable angular range is big, can fully meet to open
When support tube 1 relative to the vertical of base.
More preferably, another embodiment as the present invention, twisted axis 3 is bolt axle；
When support tube 1 is opened to the position of needs, screwed by nut with bolt axle support tube 1 and support 2 is close
Fixed, at this moment support tube 1 can not be done as rotating shaft using bolt axle and be rotated, and stability is guaranteed.When needing to fold, by nut pine
Open, at this moment support tube 1 can be done as rotating shaft using bolt axle and rotated again.
This mode, which connects, ensure that stability, and operate very easy.
More preferably, another embodiment as the present invention, in addition to bearing 6；
Rotary shaft is set on rotating disk 4（It is not shown）；
Bearing body 11 is set on base 9；
Rotary shaft is arranged in bearing body 11 by bearing 6, so that rotating disk 4 is rotated by bearing 6 relative to base 9.
So rotary shaft contact be bearing 6 inner sleeve, what bearing body 11 contacted is the overcoat of bearing 6, the cooperation at two
It is interference fits, therefore is not in phase between the inner sleeve and bearing body 11 and the overcoat of bearing 6 of rotary shaft and bearing 6
To motion, frictional force caused by rotation is only present in bearing 6 itself between rotary shaft and bearing body 11.
This mode can make rotating disk 4 more flexibly light relative to the rotation of base 9, while decrease friction and produce
Accessory loss, extend service life.
More preferably, another embodiment as the present invention, in addition to the drive division 8 of motor 7 and first；
Electric machine support 10 is set on base 9；
Motor 7 is arranged on electric machine support 10；
Second drive division 5 is set on rotating disk；
Motor and the drive connection of the first drive division；
First drive division 8 is connected with the second drive division 5, for rotating motor driving rotating disk 4.
This mode drives using motor 7 to be rotated, and be instead of handmade rotary, has been saved manpower, passed through simultaneously
The rotating operation of motor 7 realizes rotating disk 4 relative to the reciprocating rotary of base 9, so as to realize the oscillating function of support tube 1.
More preferably, another embodiment as the present invention, the first drive division 8 and the second drive division 5 are gear.
It is a kind of typical mechanical drive mode using gear drive, space can be saved, reduces noise.
More preferably, another embodiment as the present invention, in addition to bottom plate 12；
Bottom plate 12 is fixedly connected with base 9, for covering base 9.
The parts such as motor 7, bearing 6 and gear can be so protected, avoid the entrance of dust, extension uses the longevity
Life.
A kind of electric fan, include the rotatable folding structure of any of the above embodiment.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more specific and detailed, but simultaneously
Therefore the limitation to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
