Abstract
The utility model discloses a motor and a center shaft fixing mechanism of a column type electric fan, comprising a motor, a center shaft, a front shell and a motor bracket. The motor bracket is fixed on the front shell; the location-limited plate of a wabbler mechanism is arranged on the motor bracket; the center shaft is fixed on the motor bracket. The utility model has the advantages of simple structure, material saving, simple assembly technique and high production efficiency.
Description
Technical field
The utility model relates to the motor of upright post type electric fan and the fixed mechanism of axis.
Background technique
The motor of existing upright post type electric fan and axis fixed mechanism normally have dividing plate in the fore shell bottom, and motor is fixed on the fore shell dividing plate by electric machine support with to the middle axillare that swinging mechaism plays position-limiting action, during axis is fixed on the axillare.As shown in Figure 1: motor 1 is fixed on the electric machine support 4 by screw 3, and screw 14 is fixed on electric machine support 4 and middle axillare 6 on the dividing plate 12 of fore shell 8 bottoms, and axis 7 is fixed on the middle axillare 6 by nut 5.The shortcoming of this motor and axis fixed mechanism is: structure is complicated, and consumable material is more.The fore shell bottom has dividing plate, from the pressure injection angle, and the slide block of loosing core under the fore shell mould need increase, structure relative complex.Part needs to add pattern draft in manufacture process, then the angle that just exists trace to tilt between the relative housing of fore shell dividing plate has enough intensity for guaranteeing dividing plate, will have enough stiffening ribs to connect dividing plate, needs the more material of consumption, and cost also can be higher.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of motor and axis fixed mechanism of upright post type electric fan of simple in structure, material-saving is provided.
The utility model is to adopt following technological scheme to realize: the motor of this upright post type electric fan and axis fixed mechanism comprise motor, axis, fore shell, electric machine support, electric machine support is fixed on the fore shell, electric machine support is provided with the limiting board of swinging mechaism, and axis is fixed on the electric machine support.Like this, motor of the present utility model and axis fixed mechanism have been cancelled original fore shell dividing plate and middle axillare, and axis is fixed on the electric machine support, and electric machine support directly is fixed on the fore shell, and have both the limit function of swinging mechaism.
In a kind of preferred scheme, the bottom of described fore shell is provided with the double-screw bolt with the described electric machine support that fixes.Described electric machine support is by three " U " shape supports that constitute.The bottom surface of described electric machine support is as the limiting board of swinging mechaism.Described axis is fixed on the bottom surface of described electric machine support, and described axis is a hollow shaft, has on described electric machine support bottom surface and the corresponding power line cable-through hole of central axis hole.
The utility model compared with prior art has following advantage:
1. motor and axis fixed mechanism have been cancelled original fore shell dividing plate and middle axillare, and simple in structure, feed consumption reduces relatively, and guarantee the vertical concentricity of motor and apical axis better.The slide block of loosing core under the fore shell mould can be cancelled, mould structure is simplified, and can reduce cost by a relatively large margin.Simplified assembly technology, manufacturing efficiency obviously improves.
2. power line can be crossed line from the power line cable-through hole on central axis hole and the electric machine support, not only shortened the complete machine power line, and when fan waved, power line was only done to move in a small amount in central axis hole, can avoid producing the friction of power line and fore shell dividing plate and impaired potential safety hazard.
