Problem.
For reaching above-mentioned purpose, on the one hand, this utility model by the following technical solutions:
A kind of toggle with balanced structure, including crank and connecting rod, also includes balance element, described crank
Part-structure is blocked by described balance element in described crank along the circumferential direction motor process all the time；
Along the axis direction of described crank, described balance element distance synchronous motor preset width, to limit described crank edge
Axis direction moves.
Further, described balance element structure in the form of a ring, the part-structure of described crank is by the inward flange of described balance element
Block；
One end that described crank is connected with described connecting rod is circumferentially rotated in the internal ring of described balance element.
Further, one end that described crank is connected with described connecting rod has and is connected post；
Described crank is fixed together with described connecting rod by connecting post.
Further, the part-structure of described crank is that the bottom of described connection post is the most outward extending convex
Platform；
The shape of described boss is suitable with the shape of the inward flange of described balance element.
Further, described balance element is co-axially mounted with described crank.
Further, between end face and the described connecting rod of described balance element, there is gap.
Preferably, the mode that described balance element is threaded connection is fixed on the housing of described synchronous motor.
For reaching above-mentioned purpose, on the other hand, this utility model is by the following technical solutions:
Fan, including synchronous motor and fan head, also includes the crank connecting link machine as above with balanced structure
Structure；
One end of the connecting rod of described toggle is fixing with the crank of described toggle to be connected, described connecting rod
The other end be connected with described fan head.
The beneficial effects of the utility model are: be provided with balance element in this utility model, and balance element can be at the axle of crank
Limit the movement of crank on line direction, owing to being fastenedly connected between connecting rod and crank, therefore can be prevented effectively from crank and occur axially
The problem of play, reduces the friction brought because of axial float, it is to avoid noise occur because of life-time service.
Further, since be provided with, crank is carried out spacing balance element, therefore, reduce the dimensional tolerance to parts and want
Ask, thus reduce further manufacturing cost, also add the service life of parts simultaneously.
Accompanying drawing explanation
Fig. 1 is the toggle overall structure signal with balanced structure that this utility model embodiment one proposes
Figure.
In figure:
1, crank；2, connecting rod；3, balance element；4, synchronous motor housing.
Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
The utility model proposes a kind of toggle with balanced structure and there is this toggle
Fan.By arranging balance element, crank is carried out in the axial direction thereof spacing, thus it is long-term to solve prior art wind fan
Use the problem that noise easily occurs.
Embodiment one
As it is shown in figure 1, a kind of toggle with balanced structure, including crank 1, connecting rod 2 and balance element 3, institute
The part-structure stating crank 1 is blocked by described balance element 3, all the time at crank 1 in described crank 1 along the circumferential direction motor process
Axis direction on, described balance element 3 distance synchronous motor preset width, move in the axial direction limiting described crank 1.Should
Preset width is unsuitable excessive or too small, keep moderate, can either realize the restriction of position to crank 1, prevent crank 1 along it
Axis direction is moved, but can not be too small, to prevent from interfering between the two in crank 1 motor process.
As further embodiment, the part-structure of described crank 1 be the bottom of described connection post along the circumferential direction
Outward extending boss, the shape of described boss is suitable with the shape of the inward flange of described balance element 3.Described crank 1 and institute
State one end that connecting rod 2 is connected and there is connection post；Described crank 1 is fixed together with described connecting rod 2 by connecting post.
Described balance element 3 structure in the form of a ring, the part-structure of described crank 1 is blocked by the inward flange of described balance element 3, institute
State one end that crank 1 is connected with described connecting rod 2 circumferentially rotated in the internal ring of described balance element 3.The i.e. company of crank 1
Connect in the internal ring that post is positioned at balance element 3, in crank 1 rotation process, connect post and rotate along internal ring, but do not occur with internal ring
Interfere.
Carrying out in installation process to balance element 3, described balance element 3 is co-axially mounted with described crank 1, and described balance element
