The utility model comprises a rocking disk and a connecting rod, wherein, the rocking disk is arranged on a central shaft, one end of the connecting rod is connected with an eccentric shaft on the rocking disk, and the other end is connected with an eccentric shaft of a fan. The utility model is characterized in that an eccentric position of the rocking disk is provided with an eccentric wheel which can rotate around an axial lead; one end of the connecting rod is connected with the eccentric wheel on an eccentric axial lead, and the other end of the connecting rod is connected with the eccentric shaft of the fan; the eccentric distance from the eccentric axial lead to the central shaft can be varied following the rotation of the eccentric wheel around the axial lead. The utility model has simple structure, can conveniently adjust the rocking angle of the electric fan and improves the use performance of the electric fan.
Description
The utility model relates to a kind of electric fan oscillating mechanism, the specifically a kind of mechanism of panning angle from 0 ° to 180 ° of any stepless adjustment that can make electric fan.
Along with the continuous development of industrial technology and improving constantly of living standards of the people, the Consumer all has higher requirement in function, performance, style, technology and aspect such as simplify the operation to electric fan.Most connecting rod, the eccentric wheel structures of adopting of existing common electrical fan, by the angle of waving of length of connecting rod and cooperating of throw of eccentric regulating fan head, so after electric fan dispatched from the factory, the angle of waving of fan head was a fixed value.In actual use, wish that sometimes fan head waves in different angles, to obtain best effect, the efficient that performance is maximum.
The purpose of this utility model provide a kind of simple in structure, easy to operate, safe and reliable, panning angle that can make fan head from 0 ° to 180 ° degree make the oscillating mechanism of any stepless adjustment.
The utility model is to realize its goal of the invention by the following technical solutions, a kind of stepless adjustment electric fan oscillating mechanism, comprise the dish of shaking the head, connecting rod, the dish of shaking the head is installed on the central shaft, connecting rod one end is connected with the eccentric shaft of shaking the head on coiling, the other end is connected with the fan eccentric shaft, on the eccentric position of dish of shaking the head, be provided with eccentric wheel, eccentric wheel can rotate around shaft axis, one end of connecting rod is connected with eccentric wheel at eccentric shaft axis place, the other end is connected with the fan eccentric shaft, and the eccentric shaft axis on the eccentric wheel can change with the rotation of eccentric wheel around shaft axis to the throw of eccentric of central shaft.
To the eccentric wheel location influence, on the dish of shaking the head, be provided with positioning device when normally shaking the head for overcoming fan.
As further improvement of the utility model, the eccentric wheel outer gearing has resistance wheel, and head-shaking motor is provided with clutch.
As another kind of improvement the of the present utility model, be engaged with resistance wheel in the eccentric wheel, the fan gearbox is provided with clutch.
Because adopt above technological scheme, the utility model has more ideally been realized goal of the invention, the user according to actual needs, adopt manually or shake the scope of shaking the head that the mode of control is transferred the pad electric fan arbitrarily, make the usability of electric fan more perfect, and have characteristics such as simple in structure, operation facility.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is another mode of execution structural representation of the present utility model;
Fig. 3 is another mode of execution structural representation of the present utility model.
Embodiment 1:
Fig. 1 is the structural representation of the stepless adjustment oscillating mechanism of manual mode of execution, and the utility model comprises shake the head dish 2, connecting rod 3, and the dish 2 of shaking the head is installed in central shaft O
1On, the eccentric shaft O on connecting rod 3 one ends and the dish 2 of shaking the head
2Connect the other end and fan eccentric shaft O
4Connect, it is characterized in that on the eccentric position of dish 2 of shaking the head, being provided with eccentric wheel 1, eccentric wheel 1 can around
Shaft axis O
2Rotate, an end of connecting rod 3 is at eccentric shaft axis O
3The position be connected the other end and fan eccentric shaft O with eccentric wheel 1
4Connect the eccentric shaft axis O on the eccentric wheel 1
3To central shaft O
1Throw of eccentric can be with eccentric wheel 1 around shaft axis O
2Rotation change; When normally shaking the head for overcoming fan to the eccentric wheel location influence, on the dish 2 of shaking the head, be provided with positioning device 5, the locating piece of positioning device 5 adopts wearing piece, also can select to adopt snap lock pearl, positioning reed etc. by the profile characteristics of eccentric wheel 1, make eccentric wheel 1 can be under certain moment of face effect the holding position constant.
During the oscillating mechanism proper functioning, the resisting moment of 5 pairs of eccentric wheels 1 of positioning device imposes on the moment of eccentric wheel 1 greater than the fan resistance of normally shaking the head through connecting rod 3, and the fixed-site of eccentric wheel 1 is constant, and fan is by the angle swinging of setting up.
When adopting manual adjustment to wave angle, only need stir the fan head safety enclosure by adjusting the angle requirement, the moment that imposes on eccentric wheel 1 through connecting rod 3 when the power of stirring is during greater than the resisting moment of 5 pairs of eccentric wheels 1 of positioning device, and eccentric wheel 1 applies direction around O by the power of stirring
2Rotate, throw of eccentric is directly adjusted on request, after stopping to stir, eccentric wheel 1 rests on the new position of adjusting, and fan is by new adjustment angle swinging.
Embodiment 2:
Fig. 2 is the structural representation of the stepless adjustment oscillating mechanism of remote control mode, and it is that eccentric wheel 1 outer gearing has resistance wheel 4 with manual difference of the stepless adjustment oscillating mechanism of mode of execution, resistance wheel 4 with eccentric wheel 1 around O
1Axle rotates, and head-shaking motor 6 is provided with clutch 7.When adopting remote control mode to adjust panning angle, only need control to be fixed on the power on/off state of the control unit of the clutch 7 on the head-shaking motor 6, clutch 7 actions are got final product.During clutch 7 work, resistance wheel 4 is around O
1Rotation is limited by clutch 7, and eccentric wheel 1 is coiling 2 around O with shaking the head
1The power effect is changeed in the resistance that is subjected to resistance wheel 4 during rotation, and the moment that this resistance commentaries on classics power produces eccentric wheel 1 is during greater than the resistance torque of 5 pairs of eccentric wheels 1 of positioning device, and eccentric wheel 1 changes force direction around O by resistance
2Rotate, throw of eccentric is changed, the fan head swinging angle obtains adjusting.When panning angle reaches required value, clutch 7 is quit work, allow resistance wheel 4 lose the restriction of clutch 7 and eccentric wheel 1 not produced and hinder commentaries on classics power, eccentric wheel 1 rests on the position of new adjustment, and fan is by the new angle swinging of adjusting.
