Description

Ceiling fan

The utility model is about a kind of ceiling fan.

Because modern's standard of living day by day improves, decorate in the family and the also general acceptance of ceiling fan of heat radiation instrument for can be used as, and the radiating effect of a ceiling fan index attaching great importance to of Consumer especially.At present general being seen ceiling fan is very diversified, still, ceiling fan whether have better heat radiating effect, whether can the person of being used needs change two characteristics greatly that wind-force blows to becomes just that the Consumer payes attention to the most; Therefore, how to develop a kind of ceiling fan that can change wind direction arbitrarily, have better heat radiation function, become developer and MANUFACTURER already and want most several problems of solving.

Traditional ceiling fan sees also shown in Figure 1ly, and it is to be combined by fixing main shaft 10, a motor 11, a rotating disk 12 and some blades 13, and utilizes this motor 11 to drive rotating disks 12, and makes group be located at blade 13 rotations on this rotating disk 12; The ceiling fan that this kind commonly used is being sold on the market, is being used for a long time, but this kind design still has deficiency on practicability, makes its effect unclear, and tracing it to its cause is:

One, each sheet blade 13 fixed-site because of traditional ceiling fan, and each blade 13 is concentric rotations, so the wind-force that traditional ceiling fan can produce blows to can't conversion, and can only be, so plant traditional ceiling fan and demand that can't the person of being used or cooperate the variation of the interior space to reach best effect to canyon;

They are two years old, because of each blade 13 of traditional ceiling fan is concentric rotations,, and can only continue blowing with certain wind-force so the wind-force of traditional ceiling fan can't conversion, and blowing the discomfort that will cause human body down for a long time, reaching best effect so plant the demand that traditional ceiling fan really can't the person of being used.

The purpose of this utility model is to provide a kind of ceiling fan that can change wind direction arbitrarily, have better heat radiation function.

In order to achieve the above object, the purpose of this utility model is to provide a kind of ceiling fan, it is characterized in that: include:

One central shaft is to hang the body of rod that is located at the roof;

One rotating disc comprises a pivot dish and a pivot seat, and this pivot dish is hubbed on this central shaft tail end by activity, and the pivot dish locks mutually with the pivot seat, and is provided with a plurality of positioning elements in this pivot seat;

One support body comprises many swing arms and the locking ring that is positioned at the swing arm end, and adjusts the angular positioning element of swing arm and locking ring relative angle; This swing arm is to be installed on the positioning element of this pivot seat,

A plurality of ceiling fans are to be locked in the locking ring of this support body end.Utilizing the rotation generation active force of some ceiling fans and causing rotating disc is that axle revolves round the sun with the central shaft.

Described ceiling fan is characterized in that: the positioning element of this rotating disc can be the locating slot of a plurality of depressions, and the swing arm of this support body is fixedly arranged in the locating slot.

Described ceiling fan, it is characterized in that: the angular positioning element of this support body can be that swing arm two ends at this support body are provided with corresponding fixed base, this fixed base offers positioning hole relatively and laterally wears the locking screw of positioning hole, these locking ring two sides then are provided with in the positioning hole of fixed base that two protruding positioning poles just embed this swing arm, on this protruding positioning pole, be equipped with a plurality of blockings and fall into the hole, and lock in this locking screw with locking member, the blocking that utilizes locking member to embed this protruding positioning pole falls into the hole, makes locking ring be fixed on predetermined angle.

The angle that the angular positioning element of this support body is adjusted just can make ceiling fan the normal turn of flabellum and not with other element collisions.

Described ceiling fan is characterized in that: this locking member can be a screw rod.

The utility model utilizes two groups of above ceiling fans to be hubbed on the outer end of a support body, and a central affixed rotating disc of this support body, this rotating disc then is set on the central shaft, and rotating disc this central shaft rotation relatively, use the rotation of two groups of above ceiling fans and be the revolution at center constantly with the central shaft, the utility model can utilize the angular transformation that is pivoted of ceiling fan to change wind direction, and the revolution of respectively organizing ceiling fan can make the wind-force of all directions constantly change; So the utility model is a kind of coaxial rotation ceiling fan that can change wind direction arbitrarily, have better heat radiation function really.

In sum, ceiling fan of the present utility model is the outer end that the ceiling fan more than two groups is hubbed on a support body, and a central affixed rotating disc of this support body, this rotating disc then is set on the central shaft, and rotating disc this central shaft rotation start relatively; Utilization said structure, the utility model can utilize two groups of above ceiling fans to change wind direction from line translation, and this rotating disc can use the reaction force of respectively organizing ceiling fan to produce rotation function, improve heat radiation function more.

Relevant the utility model is to reach technological means and the effect thereof that above-mentioned purpose adopts, now enumerate a preferable possible embodiments and cooperate graphic detailed description as after, believe the purpose of this utility model, feature and advantage thereof, concrete understanding when obtaining thus deeply.
