Prior art, tower type fan steering structure comprises base, is connected to the coupling arrangement on base, and connection set comprises tower connection drum, and its underpart is provided with the long pin be connected with base; Top is provided with annular groove and straight line chute; Axial centre is provided with rotating shaft base; Top is provided with rotary flange, rotary flange connects with the tower drum that connects by running shaft, the position that rotary flange is positioned at annular groove is provided with motor, motor output shaft is provided with moving gear, moving gear and the fixed gear engagement be arranged in annular groove, fork is in the slideway that connects drum, by the driven by motor fork, rotate, promote the flange rotation and can realize cycle rotation, existing problems are: although can realize the big angle rotary scope, but complex structure, and fork one end liner-less, long-term use easily wearing and tearing is bad; Sliding ring and washer that tool is not wear-resisting, stable not during swing.
The model utility content
The technical problem that the utility model solves, for the above-mentioned defect of prior art, provides a kind of oscillating head mechanism, has simple in structure, practical, good stability, wear-resisting, long service life, characteristics that rotation angle is larger.
The utility model solves the technological scheme that its technical problem adopts: a kind of oscillating head mechanism comprises syncmotor, chassis, back cover, crank, swing arm, lining, sliding ring and washer.Syncmotor is fixed on above back cover, and crank and syncmotor are fixed together, swing arm connecting crank and lining, and lining is fixed on base plate, and sliding ring is placed in the groove on chassis, and washer is with together with back cover is screwed in; When syncmotor turns round, drive crank and do 360 degree swings, then act on swing arm, the drive back cover is made 81.5 degree tilt fixings and is swung back and forth, and realizes the purpose of yaw.
One groove is arranged on described chassis, described sliding ring is fixed in the groove on described chassis, and during the oscillating head mechanism yaw, between described back cover and described sliding ring, face contacts with face, described sliding ring has the effect of a support to described back cover, rocking of complete machine also had to a good booster action.
Described washer is the packing ring that adopts polyformaldehyde material to form, and on described chassis, arc track is arranged, and described washer moves back and forth along described track when yaw, and described washer is that large size contacts with described chassis, and during yaw, body comparison balance can not rocked.
Described swing arm one end by screwing, the mode connecting crank of buckle, the other end connecting bushing.
Described crank and syncmotor by screw screw, the mode of buckle is connected and fixes.
Implement oscillating head mechanism of the present utility model, there is following beneficial effect: be simple in structure, practical; Because fork one end has lining, anti-damage, the working life of prolongation oscillating head mechanism; Stable auxiliary owing to having wear-resisting sliding ring and washer to act on to swing, in the oscillating head mechanism working procedure, good stability.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is three-dimensional explosive view of the present utility model;
The crank that Fig. 2 is the utility model embodiment, swing arm and lining schematic diagram;
