Detailed Description

The invention will be further described with reference to the accompanying drawings.

As shown in fig. 1-7, a fan for preventing blade breakage includes a fan main body 10 and a plurality of blades 20 fixed on the fan main body 10, wherein a reinforcing insert 30 fixedly connected to the blades 20 is inserted into the blades 20.

By inserting the reinforcing insert 30 into the fan blade 20 and fixedly connecting the two, when the fan blade is broken, the broken fan blade is connected together by the reinforcing insert 30, so that the broken fan blade is prevented from directly falling.

In this embodiment, one end of the reinforcing insert 30 extends into the fan main body 10 along with the fan blade 20, and the other end is located outside the connecting surface 60 between the fan blade 20 and the fan main body 10. Usually, the breaking point of the fan blade is located at the connecting surface of the fan blade and the fan body, so that one end of the reinforcing plug-in 30 and the fan blade are fixed to the fan body together, the other end of the reinforcing plug-in 30 and the fixing point of the fan blade are located outside the connecting surface, and once the fan blade is broken at the connecting surface 60, the fan blade can be effectively prevented from directly falling off as long as the reinforcing plug-in 30 is not broken.

Wherein, the end of the reinforcing insert 30 extending into the fan main body 10 is fixedly connected with the fan main body 10 and the fan blades 20 through at least one set of first connecting pieces 40; the other end of the reinforcing insert 30 is fixedly connected to the fan blades 20 by at least one set of second connectors 50. When the fan blade is broken at the connection surface, the reinforcing insert 30 and the fan blade 20 are fixed to the fan main body 10 by the first connection member 40, and the broken fan blade is still fixed to the reinforcing insert 30 by the second connection member 50 to prevent the fan blade from falling. In this embodiment, the first connecting member 40 and the second connecting member 50 are both bolt assemblies.

The reinforcing plug-in unit 30 is provided with at least one through hole along the length direction thereof, the through hole is internally and fixedly provided with the breakage-proof assembly 31, and once the reinforcing plug-in unit 30 is also broken along with the fan blade at the connecting surface, the broken fan blade can still be ensured not to directly fall off by the breakage-proof assembly 31. In this embodiment, two through holes are provided, and are respectively located at the left and right sides of the reinforcing insert 30.

In this embodiment, the anti-breaking assembly 31 is a bolt assembly, which includes a bolt and a nut, the bolt is inserted into and passes through one end of the through hole, and the nut is fixed at a position where the bolt passes through the through hole and is locked, so that the screw portion can be fixed in the through hole.

Still be provided with the signal board 32 in the flabellum 20, just the one end that the signal board 32 stretches out the flabellum is provided with signal switch trigger 33, be provided with in the fan main part 10 with signal switch 11 that signal switch trigger 33 position corresponds, with fan controlling means electrical connection. In this embodiment, the portion of the fan blade 20 located in the fan main body 10 is movably connected to one end of the signal plate 32, and the rest portion is fixedly connected to the other end of the signal plate 32. When the fan blades are broken, once the broken fan blades move, the signal plate 32 is driven to move together, the signal switch trigger 33 is separated from the signal switch 11, and therefore the fan is controlled to stop automatically, an alarm signal is sent out to prompt a user, and loss is avoided.

The fan blades 20, the reinforcing inserts 30 and the signal plate 32 are positioned in the inner part of the connecting surface and are connected to the fan main body 10 through at least one group of first connecting pieces 40; the first waist-shaped hole 34 is arranged on the signal plate 32 for the first connecting piece 40 to pass through; the fan blades 20, the reinforcing plug-in units 30 and the signal plate 32 are located at the parts outside the connecting surfaces and connected through at least one group of second connecting pieces 50, and the reinforcing plug-in units 30 are provided with second waist-shaped holes 35 for the second connecting pieces 50 to pass through.

When the fan blades are broken at the connecting surface 60, the second kidney-shaped hole 35 is arranged on the reinforcing insert 30 outside the connecting surface 60, and the common mounting round hole is arranged on the signal plate 32; the ordinary installation round hole that sets up on the enhancement plug-in components 30 in connecting the face 60, and what set up on the signal board corresponding to it is first waist type hole 34, therefore, the flabellum of fracture part can outwards move a certain distance relatively enhancement plug-in components 30 under the inertia effect, can drive signal board 32 synchronous motion thereupon simultaneously to signal switch trigger 33 that is the signal board 32 tip leaves signal switch 11, thereby triggers this signal switch.

In this embodiment, the bottom of the stiffener insert 30 is provided with a groove along its length in which the signal plate 32 is secured.

In summary, according to the fan for preventing the fan blade from being broken provided by the invention, the reinforcing plug-in is arranged in the fan blade, so that the broken fan blade cannot directly fall off even if the fan blade is broken, and the signal switch is triggered after the fan blade is broken, so that the fan can be controlled to automatically stop and send out an alarm signal to prompt a user, and loss is avoided.
