Abstract
The utility model relates to an oscillating electric fan with stepless positioning, the utility model has the main point that the utility model is provided with a stepless positioning control device which is composed of a connecting rod, a V-shaped spring, a pulling rope, an indicator, a worm wheel, a worm, etc. The opening angle of the V-shaped spring is controlled through the pulling rope, and the purpose of the stepless positioning control of the oscillation opening angle of the electric fan is achieved. The utility model has the advantages of convenient operation and use.
Description
The utility model relates to the control mechanism of shaking the head of electric fan, belongs to the electric fan technical field.
Existing electric fan oscillating open angle be 0 ° or 90 ° back and forth, the control mechanism of shaking the head is gone up rotation on rotation bolt, connecting rod and the bearing that is provided with by rotating eccentricity wheel, rotating eccentricity wheel and is tied to connect and constitute.Stopping, changeing by the switch control eccentric.Control by connecting rod when eccentric wheel rotates, limit electric fan and in the scope at 90 ° of angles, back and forth wave.During the eccentric wheel stall, electric fan stops to shake the head facing to the fixed-direction blowing.In daily life, often need to adjust the size of electric fan oscillating open angle, when for example fewer in number, need to adjust the open angle of electric fan oscillating a little bit smaller, number is many and when disperseing, then need to adjust the open angle of shaking the head more greatly, but existing electric fan can not satisfy actual demand.
The purpose of this utility model is the stepless location that will provide the control of a kind of step-less adjustment the to shake the head open angle electric fan of shaking the head.
The purpose of this utility model is to realize by the improvement to existing electric fan, the stepless location electric fan of shaking the head comprises motor, fan blade, eccentric wheel, rotatingshaft, bearing, switch box, chassis, it is characterized in that electric fan is provided with the stepless positioning controlling device that is made of linkage mechanism and mechanism of twisting rope, linkage mechanism is arranged between the rotation bolt on the eccentric wheel and on the bearing, and mechanism of twisting rope is arranged in the switch box.Said linkage mechanism is by comprising that three straight connecting rods, ∧ font connecting rod and V-shaped spring connect and compose, and ∧ font connecting rod top is provided with the axis hole that is connected with the motor lower portion bearing pin.Mechanism of twisting rope is by comprising that worm gear, worm screw, indicator and stay cord form, and an end of stay cord is connected on the worm gear, and the other end of stay cord is connected on the connecting rod that V-shaped spring is set in the linkage mechanism.For ease of operation, at the worm screw end knob is set, knob is installed on the panel of switch box.Turning knob by the worm drive worm gear, drives stay cord, and the angle of control setting V-shaped spring connecting rod reaches the size of stepless positioning control electric fan oscillating open angle.
The utility model compactness rational in infrastructure is manufactured easily, and cost is low, and is easy for operation, can be according to Consumer's needs, and stepless positioning control electric fan oscillating open angle satisfies the needs in the real life, and good popularization and application prospect is arranged.
Accompanying drawing 1 is a structural representation of the present utility model, and 1 motor, 2 fan blades, 3 eccentric wheels, 4 rotate bolt, 5 bearings, 6 rotatingshafts, 7 switch boxes, 8 chassis, 9 linkage mechanisms, 10 mechanism of twisting rope, 11 knobs among the figure.
Accompanying drawing 2 is the structural representation of stepless location control mechanism of the present utility model, and 3 eccentric wheels, 4 rotate bolt, 11 knobs, 12,13,14 straight connecting rods, 15 ∧ font connecting rods, 16 V-shaped springs, 17 axis holes, 18 stay cords, 19 indicators, 20 worm gears, 21 worm screws among the figure.
Narrate embodiment of the present utility model below in conjunction with accompanying drawing.
Three straight connecting rods, ∧ font connecting rod and V-shaped spring connect and compose linkage mechanism.Be hinged between connecting rod and the connecting rod, axis hole is established on ∧ font connecting rod top, and V-shaped spring is arranged on the side lever and a straight connecting rod of ∧ font connecting rod.Worm gear, worm screw, indicator and stay cord constitute mechanism of twisting rope, and an end of stay cord is connected on the worm gear, and the other end of stay cord is connected on the connecting rod that V-shaped spring is set in the linkage mechanism.The two ends of linkage mechanism be arranged on the eccentric wheel and bearing on two rotate on the bolts, the axis hole on ∧ font connecting rod top is set on the bearing pin that motor lower portion is provided with.Mechanism of twisting rope is arranged in the switch box.The end of worm screw is provided with knob, and knob places on the switch box panel.
