For overcoming the deficiencies in the prior art, the technical problems to be solved in the utility model is: the angle demodulator that a kind of simple in structure, multistage angle adjustment of may command is provided.
The technical solution of the utility model is: a kind of controllable multi-level angle demodulator, the swing that the realization of employing eccentric adjustment piece drivening rod mechanism is shaken the head.It is provided with regulating block, connecting rod and waves piece.The two ends of connecting rod respectively with wave piece, regulating block is hinged, the other end that waves piece is connected with swing axis, the swing axis center is relatively-stationary.Regulating block changes the center once departing from the position that is hinged certain distance with connecting rod, and this gyration center is connected with the synchronous motor axle.Described regulating block profile has and at least one projection or recessed breach, and remaining part is the center circular arc consistent with gyration center; In the regulating block periphery adjustable lever cover contact is with it arranged.Because regulating block gyration center and swing axis center are relatively-stationary, like this, regulating block, connecting rod and wave piece and formed a linkage mechanism, when the adjustable lever cover contacts the circular arc position of regulating block periphery, regulating block can rotate under the drive of synchronous motor, drivening rod, connecting rod promote to wave piece and rotate, and drive the swing axis swing again.When the different circular arc of multistage radius difference or girth is set on the regulating block, just can realize that multistage angle waves angle adjustment control.This swing axis can be the swing axis of electric fan oscillating or the swing axis of other equipment that use this device.
Aforesaid adjustable lever cover comprises position-limited lever, spring, position limit socket, soft conductor rope and adjusting knob, position limit socket is fixed on the supporter, and position-limited lever is fixed on the position limit socket, position-limited lever and position limit socket Spielpassung, spring housing is on position-limited lever, and the two ends of spring contact with position-limited lever, position limit socket respectively; Position-limited lever one end contacts with the regulating block periphery, and the other end connects soft conductor rope; The soft conductor rope the other end is connected with adjusting knob.The elastic force of spring can guarantee that the position-limited lever of adjustable lever cover contacts regulating block constantly.Supporter can be special connecting plate or shell, the supporting base that uses this model utility device.
Aforesaid regulating block has the orthodrome of at least one section wide-angle long radius and the little circular arc of one section small angle minor radius, is the projection or the recessed breach of transition between orthodrome and little circular arc, and protruding or recessed breach is two crossing oblique lines or camber line; Every section little circular arc also is positioned at recessed gap portions, and both sides are projection.
In one embodiment, described regulating block has the orthodrome of one section wide-angle long radius and the little circular arc of one section small angle minor radius, and 2 projectioies are respectively arranged between orthodrome and roundlet arc two edge transitions, forms a recessed breach between 2 projectioies.
Effect intentionally of the present utility model is: adopt linkage mechanism control angle adjustment, simple in structure, cost is low, good reliability.By being set, multi-section circular arc breach or projection realized multistage angle adjustment control on regulating block.
