Abstract
The utility model discloses a fan blade anti-falling structure for a ceiling fan, which comprises a fan blade mounting seat, a fan blade handle, fan blades, a connecting piece and an elastic ring, wherein the fan blades are mounted and fixed on the fan blade mounting seat through the fan blade handle; the upper side of each leaf handle is fixedly provided with a connecting piece, and the connecting pieces are connected together through an elastic ring. As an improvement, the connecting piece is a P-shaped metal piece. The elastic ring is of a circular structure and sequentially penetrates through the ring body of the head of each connecting piece. Compared with the prior art, the method has the advantages that: according to the utility model, the P-shaped connecting pieces are fixed on each blade handle, the elastic rings are used for connecting the connecting pieces together to form flexible connection, and when the blade handles are broken, the connecting pieces and the elastic rings are matched to effectively prevent the fan blades from being thrown out and falling.
Description
Technical Field
The utility model relates to the technical field of ceiling fans, in particular to a fan blade anti-falling structure for a ceiling fan.
Background
The large industrial/commercial ceiling fan is a large-size ventilation device, the diameter of the fan is varied from 2 meters to 8 meters, the maximum length of a single fan blade can reach 4 meters due to the large diameter of the fan, and strong thrust is generated to air in the running process of the fan, so that a wind field is formed. The action can generate strong reaction force to the fan blades, the blades can swing up and down, and at the moment, the blades, the blade handles and the chassis are connected to form a lever effect, so that the stability of the blade materials and the safety of the structure are greatly threatened. Along with the increase of the running time, the generation of metal fatigue easily causes the fan blade to swing up and down and vibrate to be aggravated when the fan blade runs at high speed, thereby causing the fan blade or the blade handle to break and fall, and often causing serious safety accidents.
At present, all connect with I style of calligraphy iron sheet between the flabellum of current commercial ceiling fan and the petiole, 5-6 iron sheet front and back ends are respectively perforated and are fixed in proper order on the petiole bolt, in case take place the petiole fracture, the instantaneous great downward pulling force of flabellum can make the rigid iron sheet perk to produce transverse shearing force to the bolt and prizing the bolt and break, lead to the iron sheet inefficacy, the flabellum drops.
Disclosure of Invention
The utility model aims to solve the technical problems and solve the technical difficulties, and provides a fan blade anti-falling structure for a ceiling fan, which can more effectively place the fan blade to fall after being broken.
In order to solve the technical problems, the technical scheme provided by the utility model is as follows:
the fan blade anti-falling structure for the ceiling fan comprises a fan blade mounting seat, a fan blade handle, fan blades, a connecting piece and an elastic ring, wherein the fan blades are fixedly arranged on the fan blade mounting seat through the fan blade handle;
the upper side of each leaf handle is fixedly provided with a connecting piece, and the connecting pieces are connected together through an elastic ring.
As an improvement, the connecting piece is a P-shaped metal piece. The elastic ring is of a circular structure and sequentially penetrates through the ring body of the head of each connecting piece.
Compared with the prior art, the utility model has the advantages that: according to the utility model, the P-shaped connecting pieces are fixed on each blade handle, the elastic rings are used for connecting the connecting pieces together to form flexible connection, and when the blade handles are broken, the connecting pieces and the elastic rings are matched to effectively prevent the fan blades from being thrown out and falling.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
As shown in the figure: 1. a fan blade mounting seat; 2. a petiole; 3. a fan blade; 4. a connecting piece; 5. an elastic ring; 6. and (5) a bolt.
Detailed Description
In the description of the present utility model, it should be understood that the terms "center," "lateral," "upper," "lower," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the utility model and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the utility model. Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present utility model, unless otherwise indicated, the meaning of "a plurality" is two or more. In addition, the term "include" and any variations thereof are intended to cover a non-exclusive inclusion.
The present utility model will be described in further detail with reference to the accompanying drawings.
The utility model provides a flabellum anti falling structure for ceiling fan, includes flabellum mount pad 1, petiole 2 and flabellum 3, flabellum 3 passes through petiole 2 installation and fixes on flabellum mount pad 1, above be the prior art structure that is well known to the person skilled in the art.
The fan blade anti-falling structure for the ceiling fan further comprises a connecting piece 4 and an elastic ring 5;
specifically, the connecting piece 4 is a P-shaped metal piece, and the body part is fixed on the upper side of the blade stem 2 through a pair of bolts 6; the elastic ring 5 is of a steel wire circle structure, and the elastic ring 5 sequentially penetrates through the ring bodies of the heads of the connecting pieces 4;
the working principle of the embodiment is as follows: the elastic ring 5 and each connecting piece 4 form movable connection, once the phenomenon of breakage of the blade handle 2 occurs, the connecting pieces 4 on the blade handle 2 can be matched with the elastic ring 5 to prevent the fan blade 3 from being thrown out, and as the connecting pieces 4 and the elastic ring 5 are flexibly movably connected, the elasticity of the elastic ring 5 can effectively buffer the tensile force, and the prying action on the elastic ring 5 caused by the instant large downward pulling force of the fan blade 3 can be eliminated, so that the fan blade is safer.
The utility model and its embodiments have been described above with no limitation, and the actual construction is not limited to the embodiments of the utility model as shown in the drawings. In summary, if one of ordinary skill in the art is informed by this disclosure, a structural manner and an embodiment similar to the technical solution should not be creatively devised without departing from the gist of the present utility model.
