Abstract
The utility model discloses a device for connecting vanes and an impeller system of a large ceiling fan. The device is mainly provided with connecting measures such as a locking nut for locking the impeller and a transmission coupler, an impeller security sheet, a vane security sheet and the like. The connecting device adopts multiple safe self-locking devices and can effectively avoid the safety risk due to running of the large ceiling fan.
Description
(1) technical field
The utility model relates to the connection set of a kind of large-scale energy-saving Blade for ceiling fan system, is specifically related to the structure and the behavior characteristics of this kind device.
(2) background technique
Current ceiling fan product fan blade is directly fixed blade and impeller with bolt with all employings that is connected generally of impeller, and household type ceiling fan and industrial ceiling fan all adopt this kind Placement.When the Blade for ceiling fan radius is within 2 meters, adopt the common Placement of this kind that certain safety guarantee coefficient still can be arranged, but when if the length of fan blade and weight increase, adopt the connection of this kind common mode not satisfy the safety requirement of fan, very easily cause the accident that causes leaf abscission or fracture inadequately because of join strength.
(3) summary of the invention
The utility model mainly provides a kind of connection set of the fan blade that uses for large-scale ceiling fan.
The safe self-locking system of the owned multiple structure of connection set of large-scale Blade for ceiling fan of the present utility model, form by parts such as flabellum, flabellum safety plate, impeller safety plate, impeller, support, motor, speed changers, electric fan is fixed on the impeller with a kind of flabellum safety plate that is designed to crooked shape, and an end of flabellum safety plate bending can be fixed with the high strength screw with another sheet flabellum, impeller.After impeller and speed changer hitch bar chassis adopted locking nut fixing, it was fixing to adopt 6 impeller safety plates to strengthen again.Fan electromotor and speed changer all are fixed on the support.Adopt the fan of this kind connection set to guarantee the safety of large-scale ceiling fan when operation, effectively avoided the generation of the direct personal injury accident that general fan brought.Also because of its ingenious design in self-locking system, more make this kind ceiling fan impeller system in the problem that lowers the fan work noise, bring into play important function simultaneously.
The connection set contrast of the utility model and common Blade for ceiling fan, its beneficial effect is embodied in:
1, this connection set is applicable to that the blade of large-scale ceiling fan connects, and its blade maximum working radius can reach about 3.5 meters.
2, this device has the vanes fixed system of multiple structure, has improved large-scale ceiling fan Safety performance in the course of the work greatly.
3,, thereby make this kind ceiling fan impeller system when work, can effectively lower the noise that the blast fan system brings because of this kind connection set all adopts ingenious design in each self-locking system
(4) description of drawings
Fig. 1 is the utility model structural drawing
(5) embodiment
What the utility model mainly solved is the connection set of a kind of large-scale Blade for ceiling fan and impeller system.As shown in the figure, 5. fan electromotor reaches speed changer and 6. all is fixed on an integral support and 4. goes up, and the support upper end is hinged together with the lifting fixing device of blower fan, and lower end and speed changer bottom is 6. fixed.
2. the impeller safety plate is to be fixed on the impeller by nut, and the locking nut that is connected with the speed changer hitch bar when impeller is because of reason such as aging, when not having carrying and lock ability, the easy landing of impeller, personal security is very easily threatened, and at this moment, 2. the impeller safety plate just bears the two-stage safety effect.7. the bottom of each impeller safety plate and impeller are fixed with 2 high strength screws, and the upper end fastens the chassis of speed changer hitch bar, bear the two-stage safety system jointly by 6 safety plates.
Flabellum safety plate among the figure 3., its straight end totally two fixed hole positions adopt 2 high strength screws fix flabellum 1. with impeller 7..The forniciform particular design of flabellum safety plate can make an end of flabellum safety plate bending fix with the high strength screw with another sheet flabellum, impeller again, has more guaranteed its Security.
By the connection of above multiple mode, guaranteed the Security of flabellum and impeller.
Claims (4)
1. the connection set of a large-scale Blade for ceiling fan, comprise flabellum, flabellum safety plate, impeller safety plate, impeller, support, motor, speed changer, it is characterized in that: described flabellum is fixed on the impeller with the flabellum safety plate, described impeller and speed changer hitch bar chassis are strengthened fixing with the impeller safety plate, described motor and speed changer all are fixed on the support.
2. the connection set of large-scale Blade for ceiling fan according to claim 1 is characterized in that impeller is connected with the speed changer hitch bar also to adopt locking nut to fix.
3. the connection set of large-scale Blade for ceiling fan according to claim 1 is characterized in that 6 impeller safety plates are adopted on the chassis of impeller and speed changer hitch bar.
4. the connection set of large-scale Blade for ceiling fan according to claim 1, it is characterized in that adopting flabellum and being connected of impeller a kind of flabellum safety plate of bending to connect, an end of flabellum safety plate bending can be fixed with the high strength screw with another sheet flabellum, impeller.
