Abstract
The utility model discloses a simple stepless modulation wobbling angle machinery with auto-clutch function suitable for the electric fan and instrument characterized in that a middle regulating device is designed and hinged with the middle portion of a rocking rod to enable the wobbling angle of a wobbling angle mechanism, a connecting rod and a common eccentric wheel crank can be continuously adjusted with stepless in running and auto-clutch function. The utility model has the characteristics of simple structure, high reliability, simplicity, economical performance, etc.
Description
A kind of simple type automatic clutch stepless is regulated pivot angle mechanism.
The utility model is relevant with machinery, is suitable for doing the pivot angle device of electric fan and instrument.
Usually the pivot angle of electric fan is changeless, and the pivot angle of senior electric fan is made into stepping to be regulated.As everyone knows, the changeless electric fan of pivot angle is very not convenient in the use.And the senior electric fan of the adjustable pivot angle of stepping is because of complex structure, and cost is higher and limited self a large amount of productions.
One of the purpose of this utility model is that the stepping that will solve senior electric fan is regulated pivot angle assembling device complex structure, and cost is higher, is not suitable for mass-produced problem, and further purpose is to provide a kind of simple type automatic clutch stepless to regulate pivot angle mechanism.
Regulate pivot angle mechanism by simple type automatic clutch stepless described in the utility model, generally form, it is characterized in that having the suitably intermediate regulations device of design of a warp by base, eccentric wheel crank, fork, connecting rod, control handle, control backguy and intermediate regulations device.This device is contained in the middle part of fork with hinge pin screw hinge.A hinge dress eccentric wheel crank of fork, the other end hinge is contained on the base; By a connecting rod, the rotation of eccentric wheel crank is become the swing of intermediate regulations device.The method of control intermediate regulations device amplitude of oscillation size has various ways, and suitable to select a kind of method wherein for use be the size of the may command intermediate regulations device amplitude of oscillation; By one with base and the hinged connecting rod of intermediate regulations device.The swing of intermediate regulations device has become the swing of fork, and correspondingly, the size of swinging angle of swinging rod also becomes adjustable.
Because feature of the present utility model place is as long as select the method (only having provided so a kind of method in the drawings and Examples of this specification) of suitable control intermediate regulations device amplitude of oscillation size.Just can make the described pivot angle mechanism continuous stepless ground that can be in operation regulate pivot angle, simple in structure, reliable and advantage such as automatic clutch function arranged.
Description of drawings and embodiment:
Fig. 1 is that the said simple type automatic clutch stepless of the utility model is regulated the plan view of pivot angle mechanism.Because control handle (20) is standardized, so adopt the simple technique of painting.The mounting point of control handle is decided according to the actual requirements in addition.At this is on the position of just drawing for the ease of expression in the drawings.In Fig. 1, write the method label of Arabic numerals in the circle of employing garden, become bracket for ease of " typewriting " Jiang Yuanquan in this manual.
In the present embodiment, form by swing chute (14) slide bar (9), Returnning spring (7) and support (6) by intermediate regulations device described in the utility model.Chute (14) is contained in the middle part of fork (13) by countersunk head hinge pin screw (1) hinge; Cable wire in the control backguy (16) passes support (6) and Returnning spring (7) inserts in the aperture of slide bar (9) one ends.And housing screw (8) compresses it.Hinged from appropriate location with a hinge (2) and connecting rod (5) apart from this end distance.The other end of connecting rod (5) is hinged with hinge (3) and connecting rod (4) with the other end of the hinged slide bar of base (19) (9) with hinge (17).And it is the other end and the eccentric wheel crank (10) of connecting rod (4) is hinged with a hinge (12); With (four) screws (15) support (6) is contained in together with slide bar (9) that swing chute (14) is gone up, support (6) is fixed, slide bar (9) is deep in the groove of its both sides because of screw (15), so can only slide along chute.One of fork (13) is hinged with hinge (18) and base (19), and the other end is hinged with hinge (11) and eccentric wheel crank (10).Control handle (20) is fixed on the base (19), during use, if control handle is allocated to the maximum pendulum angle position, the cable wire pulling slide bar (9) in the control backguy (16) make hinge (3) move to the minimum place of countersunk head hinge pin screw (1) distance (this distance should greater than the effective radius of crank) because interlock.Hinge (2) move to countersunk head hinge pin screw (1) apart from biggest place, simultaneously Returnning spring (7) is compressed.The rotation of eccentric wheel crank (10) by connecting rod (4), become slide bar (9) and the swing chute, the swing of (being described intermediate regulations device).This moment amplitude of oscillation maximum; Because the effect of connecting rod (5) makes fork (13) produce the swing of amplitude peak.If control handle (20) is dialled from the maximum pendulum angle position to a certain position less than zero-bit.Returnning spring (7) promotes slide bar (9), makes hinge (2) shift near countersunk head hinge pin screw (1).Because interlock, hinge (3) increases with the distance of countersunk head hinge pin screw, and clearly, this moment, the pivot angle of described intermediate regulations device diminished.Correspondingly the pivot angle of fork (13) also diminishes, and carries out but be in operation with it is equally clear above-mentioned adjustment process continuous stepless.If control handle (20) is pushed zero-bit.Returnning spring passes slide bar (9) to dead in line place that makes the axis and the countersunk head hinge pin screw (1) of hinge (2) just, because interlock, hinge (3) move to countersunk head hinge pin screw (1) apart from biggest place, this moment described intermediate regulations device pivot angle minimum but because the axis of hinge (2) and the dead in line of countersunk head hinge pin screw (1).Fork (13) is not swung, and it is worthy of note, pivot angle described in the utility model mechanism can be when continuous stepless ground be regulated to the scope of certain appointment from zero, from motionless to moving, in other words from to closing; Driven to motionless, in other words from be incorporated into from, all only just when regulating pivot angle big or small, automatically finish.Clearly, this automatic clutch function is the another inherent characteristic of pivot angle described in the utility model mechanism.
Simple type automatic clutch stepless described in the utility model is regulated the pivot angle mechanism that requirement that pivot angle mechanism is very suitable for doing electric fan and instrument can be regulated continuously, as long as with the base in the accompanying drawing (19) fork (13), eccentric wheel crank (10) control handle (20) is done suitable variation and can be used.
