Description
Technical Field
The utility model relates to an electric fan adjustment mechanism that shakes head.
Background
Electric fans used in daily life are generally provided with an oscillating device so as to enlarge the blowing area of the electric fan. At present, the oscillating device of a common table type electric fan is composed of a gear speed reducing mechanism and a corresponding control mechanism of a crank rocker mechanism, and a crank of the crank rocker mechanism converts rotary motion transmitted from the gear speed reducing mechanism into reciprocating swing of a rocker so as to realize oscillating motion of the fan. However, because the length of the crank is fixed and the swing angle of the rocker is determined by the specific structural size of the crank mechanism, the general electric fan can only supply air in a reciprocating manner within a fixed angle range, the swing angle cannot be adjusted, and a lot of inconvenience exists in daily life use.
Chinese patent ZL 201821590193.0 discloses an oscillating adjusting mechanism for electric fan, but in the rotating process of the adjusting wheel, because the exposed end of the spring of the fastening screw ii supports against the steel ball, the steel ball and the spring may rotate with the adjusting wheel to block the adjusting wheel, so that the adjusting wheel cannot rotate and is ineffective. And the screw on the regulating wheel is screwed by hands, and can be loosened during reverse regulation.
Disclosure of Invention
The utility model aims at providing an electric fan adjustment mechanism that shakes head to the defect that exists among the prior art, but a simple structure, convenient to use angle of adjustment size.
The utility model adopts the technical proposal that: an electric fan oscillating adjusting mechanism comprises a shaft sleeve and an adjusting wheel; the top of the shaft sleeve is provided with a connecting sleeve connected with the output shaft of the motor, and the connecting sleeve is arranged close to the edge of the top surface of the shaft sleeve; a set screw is arranged on the side wall of the connecting sleeve; the adjusting wheel is arranged in the shaft sleeve, a set screw II is arranged on the side wall of the shaft sleeve, and a glass bead screw is adopted as the set screw II; an annular groove is formed in the side wall of the adjusting wheel, a plurality of hemispherical grooves are formed in the bottom of the annular groove, and steel balls at the front end of the glass ball screw can be embedded into the hemispherical grooves; the edge of the bottom of the adjusting wheel is provided with a threaded hole, a screw is arranged in the threaded hole, and the screw is used for being hinged with the end part of a connecting rod on the electric fan frame.
In the oscillating adjusting mechanism of the electric fan, the bottom of the adjusting wheel is also provided with an inner hexagonal hole.
In the oscillating adjusting mechanism of the electric fan, the set screw II is provided with the locknut.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model has simple and compact structure and low cost; the bottom of the utility model is provided with the hexagon socket hole which is used for matching with the hexagon wrench, and the adjusting wheel is prevented from rotating when the screw is tightened, so that the adjusting wheel and the screw are reliably connected; the utility model discloses a holding screw II adopts the glass bead screw, in the ability positioning adjustment wheel, the emergence of the dead regulating wheel trouble of steel ball and spring catch when can prevent the regulating wheel rotation.
Drawings
Fig. 1 is a front view of the present invention.
Fig. 2 is a plan view of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 and 2, the utility model comprises a shaft sleeve 1 and an adjusting wheel 2; the top of the shaft sleeve 1 is provided with a connecting sleeve 11 connected with the output shaft of the motor, and the edge of the connecting sleeve 11 close to the top surface of the shaft sleeve 1 is arranged. The side wall of the connecting sleeve 11 is provided with a set screw 12 for fixedly connecting with an output shaft of the motor. Adjusting wheel 2 arrange in axle sleeve 1, be equipped with holding screw II on the 1 lateral wall of axle sleeve, holding screw II can be fixed adjusting wheel 2. The edge of the bottom of the adjusting wheel 2 is provided with a threaded hole, a screw 21 is arranged in the threaded hole, and the screw 21 is used for being hinged with the end part of a connecting rod on the electric fan frame. In order to ensure that the adjusting wheel 2 is reliably connected with the screw 21, the bottom of the adjusting wheel 2 is also provided with a hexagon socket 24, and the fixing (non-rotation) of the adjusting wheel 2 is realized when the screw 21 is installed by the aid of a hexagon wrench.
The side wall of the adjusting wheel 2 is provided with an annular groove 23, and the bottom of the annular groove 23 is provided with a plurality of hemispherical grooves 22. The set screw II 13 is a glass bead screw, and a steel ball at the front end of the glass bead screw can be embedded into the hemispherical groove 22. The set screw II 13 can realize that the regulating wheel 2 is fixed, and due to the deformability of the glass bead screw, the regulating wheel 2 can be allowed to rotate to realize the regulation of the swing amplitude of the electric fan. The set screw II 13 is provided with the locknut 14, so that the set screw II 13 can be prevented from loosening, the adjusting wheel 2 can freely rotate, and the accurate oscillating amplitude of the electric fan can be obtained.
The utility model discloses during the use, only need rotate regulating wheel 2, adjust the positional relation of screw hole and connecting sleeve 11, can adjust the electric fan and shake the head swept angle size, easy operation has realized adjusting the electric fan moreover and has shaken the head swept angle size.
