Description

ceiling fan

【Technical field】

The utility model relates to a ceiling fan.

【Background technique】

We know that a ceiling fan is mainly composed of a motor and several blades. The motor includes a stator and a rotor. At this stage, each blade is connected to the rotor through a stamping part—the blade frame. When installing, the two ends of the blade frame are respectively Screws are used to fix the rotor and the root of the blade, which is not only cumbersome to install, but also has many procedures, resulting in high production costs; moreover, it is easy to cause the blade to swing when it rotates, making the ceiling fan not work smoothly, and it will produce a large vibration when rotating at high speed. noise.

【Content of utility model】

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a ceiling fan with reasonable structure, convenient installation, stable operation, low noise and beautiful appearance.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions:

A ceiling fan, comprising a motor and blades, wherein the blades are in the shape of a propeller, a connecting plate is arranged on the rotor of the motor, the root of the blade corresponds to the outline of the connecting plate, and a boss is arranged inside the root of the blade , a blade fixing structure is provided between the connecting plate and the boss.

In an improved solution to the above-mentioned ceiling fan, the shape of the connecting plate is circular; the blade root and the boss therein are matched with the circular connecting plate.

In the improved solution to the above-mentioned ceiling fan, there are two upper and lower connecting discs, and two upper and lower layers of bosses.

In an improvement to the ceiling fan above, the blade fixing structure includes at least two pairs of connecting columns and sockets, and screws tightened on the connecting columns, and the connecting columns and sockets are respectively arranged on the connecting plate and the on the boss.

In an improvement to the ceiling fan above, the blade fixing structure includes at least two pairs of connecting columns and sockets, and screws tightened on the connecting columns, and the connecting columns and sockets are respectively arranged on the boss and on the connection plate.

Compared with the prior art, the beneficial effect of the utility model is: when installing the blade, only need to put the root of the blade on the corresponding position of the connection plate, and then lock and fix it with the fixing structure. Its structure is more reasonable and the installation is convenient. It is very easy to disassemble and transport in daily life; in addition, since the blades are directly installed on the connecting plate of the rotor instead of through the blade frame, the possibility of shaking the blades can be reduced, so that the work of the ceiling fan is easier. Stable and low noise; at the same time, the blades are in the shape of a propeller, and the roots of all the blades basically cover the entire motor and the connection plate on it. The motor and the connection plate cannot be seen from the outside, which can make the shape of the ceiling fan Beautiful, three-dimensional streamlined, more natural and soft blowing effect.

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

【Description of drawings】

Fig. 2 is the bottom view of Fig. 1;

Fig. 3 is the three-dimensional view of the motor of the utility model embodiment;

Fig. 4 is the perspective view of the blade of the utility model embodiment;

Figure 5 is a schematic diagram of the assembly of the embodiment of the present invention (with a single blade).

【Detailed ways】

The utility model is a ceiling fan, as shown in Figures 1, 2, and 5, which includes a motor 1 and several blades 2, wherein the blades 2 are in the shape of a propeller, which can make the entire ceiling fan more beautiful in appearance and have a better blowing effect. Natural and soft; the rotor of the motor 1 is provided with a connection plate 3, and the root portion 21 of the blade 2 corresponds to the outline of the connection plate. Since the outline of the connection plate 3 is generally circular, the blade root 21 is arc-shaped at this time; A boss 22 is arranged inside the blade root 21 , and a blade fixing structure 4 is arranged between the connecting plate 3 and the boss 22 . The connection plate 3 is generally directly set on the motor rotor. When installing the blade, just put the blade root on the corresponding position of the connection plate, and then lock and fix it with the fixing structure 4. It can be seen that the utility model The structure is more reasonable, the installation is convenient, and it is very easy to disassemble and transport in daily life. In addition, since the blades are directly installed on the connecting plate of the rotor instead of through the blade frame, the possibility of shaking the blades can be reduced, so that the work of the ceiling fan is more stable and the noise is low; at the same time, all blades The root of the fan (here it is arc-shaped) basically covers the entire motor and the connection plate on it, and the motor and the connection plate cannot be seen from the outside, which can make the ceiling fan beautiful in appearance and strong in three-dimensional streamlines.

In this embodiment, as shown in FIG. 3 , the outline of the connection plate 3 is circular, and the root 21 of the blade 2 and the boss 22 inside it are arc-shaped (as shown in FIG. 4 ), that is, it is in line with the circular Connect the discs to match.

The blade fixing structure 4 can be of different structures. In this embodiment, it includes at least two pairs of connecting posts 41 and sockets 42, and screws 43 tightened on the connecting posts 41. Here, there are three pairs of connecting posts and sockets. , and the connecting post 41 and the socket 42 are respectively arranged on the connecting plate 3 and the boss 22. When installing, as shown in FIG. After the connecting column 41 is sleeved and pressed, then use the screw 43 to lock it. In this embodiment, the connecting plate 3 has two upper and lower ones, and the boss also has two upper and lower layers, which can make the installation of the blades more firm and safe, and the rotation is more stable. Usually, it is used between the lower connecting column and the socket. Screw tight. Certainly, the connection post 41 and the insertion hole 42 can also be arranged on the boss and the connection pad respectively in reverse.

Auxiliary devices such as lampshades 5 can also be set on the ceiling fan.
