Standby middle radiating and cooling makes electronic component normal table work, and fan is employed for the every aspect of people's life.But it is general
Fan volume it is larger, the steering of rotation is smaller, inconvenient to carry, can heat dissipation region it is smaller, therefore often result in the tired of people
It disturbs.
Application No. is the patents of CN201020145448.X to disclose a kind of Portable fan, including fan head, pedestal, with
And the bracket for being set on the base fan head, the bracket are folding rack comprising first support, second support, third
One end of bracket, first support is fixedly connected with pedestal, and the other end is flexibly connected with one end of second support, second support it is another
One end is flexibly connected with one end of third bracket, and fan head is arranged on third bracket.The utility model, which has, to occupy little space,
Advantage easy to carry, easy to use.
Although the utility model patent occupied space is smaller, easy to carry, wherein it is set as between fan and pedestal
Folding rack is difficult to be totally turned between second support and third bracket, and third bracket is being opened to certain journey clockwise
After degree, the edge for being limited by second support hinders, and causes folding rack rotation insufficient, so that electric fan is difficult to carry out large area
Heat dissipation region needed for covering.In addition, the patent for a long time turn folding between bracket after-poppet occur loosen be easy to cause bracket
It is difficult to support fan, so that it can not carry out the adjustment of height and wind direction.
Utility model content
The purpose of this utility model is that: it solves to fold electric fan in the prior art and is difficult to large area and freely adjusts wind direction
Problem provides a kind of electric fan that can freely adjust wind direction that can cover more large area region.
The technical solution adopted in the utility model is as follows:
A kind of electric fan that can freely adjust wind direction, including mounting rack and the fan body being arranged in mounting rack, institute
Stating mounting rack includes the footstock being successively hingedly arranged, first support, second support and pedestal, and the fan body is mounted on top
On seat.
Wherein, the junction of first support and second support is additionally provided with the articulated joints of control rotation, described hinged
Connector includes the fluted disc in the upper chamber of first support and being fixedly connected in the epicoele chamber interior walls of first support, is located at
The bottom chamber of second support is simultaneously hinged on left anti-bull stick and right anti-bull stick on the lower chambers inner wall of second support in the first from left right side,
Fluted disc include coaxial arrangement large fluted disc, small tooth plate, large fluted disc, small tooth plate outer rim be respectively provided with teeth, the cavity of resorption of second support
It is provided with a vertical bar between two groups of anti-bull sticks in chamber interior walls, one end of vertical bar is hinged with left connecting rod and right connecting rod, left
The other end of connecting rod is articulated in the middle part of left anti-bull stick, and the other end of right connecting rod is articulated in the middle part of right anti-bull stick, the end of left anti-bull stick
Portion, right anti-bull stick end be the bending section that can be caught in adjacent two tooth on same fluted disc.
Wherein, left connecting rod, right connecting rod are articulated in the same point of vertical bar.
Wherein, articulated connection is again provided between the footstock and first support and between second support and pedestal
Part.
Wherein, spring clip is provided on pedestal.
Wherein, protective shell is additionally provided on footstock.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
