Abstract

A blade for an industrial ceiling fan is characterized in that the cross section of the blade is crescent-shaped, wherein an inner chamber is arranged in the hollow blade body; a guide groove extending out of the wall of the inner chamber is formed on the wall of the inner chamber; and a plurality of reinforced ribs further extend out of the chamber wall on two sides of the guide groove. The blade, with a simple structure, has the advantages that the guide groove formed on the wall of the inner chamber can be directly and conveniently inserted into a fixing plate in a manner corresponding to a guide rail on the fixing plate; in addition, the reinforced ribs are further arranged on the wall of the inner chamber, so that the strength of the blade body can be enhanced and the service life is prolonged when the blade is in use.

Description

The industry ceiling fan blade

Technical field

The utility model relates to a kind of ceiling fan blade, particularly a kind of industrial ceiling fan blade.

Background technique

Ceiling fan is used in existing large scale industry, and its blade has tens meters not wait to tens meters, the running of motor rotating band moving vane propeller cavitation, the angled cutting air movement of doing of blade and horizontal plane, thereby generation wind-force.But longer because of blade, in rotary course, centrifugal force is bigger; The requirement of strength of blade lamellar body is just higher, and existing ceiling fan blade adopts the grafting form mostly, above the fixed tray that the blade of hollow is plugged into rotor links to each other; Fix with screw, and the cavity of blade hollow is greater than the section area of the joint of fixed tray and blade, whole blade will be when inserting could be fixed with screw laterally or vertically having aimed at screw for this reason again; Trouble is installed; Used of a specified duration and also can be shifted, very inconvenience, and also dangerous.

Summary of the invention

The purpose of the utility model is exactly that a kind of ceiling fan blade is provided for the deficiency that addresses the above problem.

The utility model the technological scheme that will deal with problems following:

Said industrial ceiling fan blade; It is characterized in that: said ceiling fan blade is crescent shape in its cross section lamellar body bending; Said blade lamellar body hollow is provided with inner chamber, and wall is provided with the guide groove that wall extends out from the chamber in blade inner chamber chamber, on the chamber wall of blade guide groove both sides, also extends the plurality of strengthening ribs bar.

Described reinforced rib is two.

The beneficial effect of the utility model is following:

The utility model is simple in structure, and wall is established guide groove in blade inner chamber chamber, when inserting fixed tray; Guide rail on the corresponding fixed tray directly just can insert, and is very convenient, and blade inner chamber chamber wall is also established reinforced rib; Make blade in use, can strongthening plate intensity, increase working life.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the schematic cross-section of the utility model;

Fig. 3 is the user mode reference drawing of the utility model.

Among the figure: 1, lamellar body; 2, inner chamber;

3, guide groove; 4, reinforced rib.

Embodiment

The utility model is done the elaboration of further detail below in conjunction with accompanying drawing;

Consult Fig. 1, Fig. 2; Said ceiling fan blade is crescent shape in its cross section lamellar body 1 bending; Said blade lamellar body 1 hollow is provided with inner chamber 2, is provided with the guide groove 3 that wall extends out from the chamber at blade inner chamber 2 chamber walls, on the chamber wall of blade 1 guide groove 3 both sides, also extends plurality of strengthening ribs bar 4; Described reinforced rib 4 is two.

When used, the guide slot 3 on the guide plate from the fixed plug, and then fixed with screws, as a strengthening Zhu strips 4, increasing the strength of the blade body 1, to increase the service life of the blade.

Claims (2)

1. industrial ceiling fan blade; It is characterized in that: said ceiling fan blade is crescent shape in its cross section lamellar body bending; Said blade lamellar body hollow is provided with inner chamber, and wall is provided with the guide groove that wall extends out from the chamber in blade inner chamber chamber, on the chamber wall of blade guide groove both sides, also extends the plurality of strengthening ribs bar.

2. industrial ceiling fan blade according to claim 1 is characterized in that: described reinforced rib is two.
