Description

Technical Field

[0001] The utility model relates to a fan lamp, in particular to a motor fixing cover of the fan lamp. Background Art

[0002] With the development of the times, in order to cope with global warming, energy conservation and emission reduction have received more and more attention from people. This is reflected in the fact that people's energy-saving requirements for household appliances have become a trend in daily life. Under this energy-saving trend, air conditioners are gradually being replaced by flexible and energy-saving fans due to their high energy consumption. Fan lights have the dual functions of fans and lighting because they can increase the blowing range of the fan by shaking their heads. They are becoming more and more popular and are widely used in furniture life. However, the fan light structures currently used in the market are generally composed of a motor, a fan blade and a lamp. The motor also includes a synchronous motor and a shaking head component to realize the shaking head function. In actual application, in order to protect the motor components and strengthen the force stability of the motor, fan blades, and shaking head components, an additional protective cover or a lamp plate is required. When the fan motor shakes and rotates, the friction between the fan motor shaft and the protective cover or the lamp plate causes wear, which not only generates noise, but also causes swings due to instability when shaking the head. This not only affects the user experience, but also affects the durability of the product and shortens the service life of the product. Summary of the invention

[0003] The utility model aims to provide a motor fixing cover of a fan lamp with a more reasonable structure and more stable performance, so as to solve the problems raised in the above-mentioned background technology and make it more valuable for industrial use.

Bearing two is sleeved and fixed on the upper part of the motor shaft. A mounting hole is integrally formed just below the lamp ancient plate. The aperture size of the mounting hole is the same as the outer diameter size of bearing one and is tightly matched. The outer cylinder size of the annular cylindrical ball head is the same as the inner hole diameter of bearing one and is tightly matched. The annular cylindrical ball head is provided with an axial hole with an aperture size that is the same as the outer diameter size of the motor shaft at an angle of 12 to 30 arcs from the upper end face downward along the central axis of the cylinder. The annular cylindrical ball head is coaxially provided with an embedding groove with an aperture size that is the same as the outer diameter size of bearing two from the upper end face downward along the direction of the axial hole.

[0005] As a further measure, the axial hole penetrates from the upper end surface of the annular cylindrical ball head downward along the central axis of the cylinder at an arc angle.

[0006] As a further measure, a mounting hole protruding inwardly to form an annular stepped convex edge is integrally formed directly below the lamp base.

[0007] As a further measure, the annular cylindrical ball head is made of hard plastic material.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: during installation, the synchronous motor screws are fixed on the synchronous motor fixing plate, the upper end of the shaking head device is fixedly connected to the rotating part of the synchronous motor through the synchronous motor fixing plate, and the lower end of the shaking head device is fixedly connected to the fan motor, and then the bearing is embedded and fixed on the mounting hole of the lamp ancient plate, and the annular cylindrical ball head is embedded and fixed in the inner hole of the bearing.
