Fan with anti-falling structure

Abstract

A fan with an anti-falling structure, including a mounting portion configured to be fixed to a wall, a fixed shaft connected to the mounting portion, a drive motor rotatably connected to the fixed shaft, and a plurality of fan blades fixed to the drive motor. An anti-falling rope is connected to an upper end or a lower end of the fixed shaft, and a connection structure is provided between a lower end of the anti-falling rope and the fixed shaft to fixedly connect them. An upper end of the anti-falling rope is fixed to the mounting portion or the wall. In this way, the anti-falling rope may restrain the drive motor when the connection structure between the mounting portion and the fixed shaft fails, preventing the drive motor and components connected thereto from falling, thereby avoiding injury to personnel below or damage to furniture.

What is claimed is: 
     
         1 . A fan with an anti-falling structure, comprising a mounting portion configured to be fixed to a wall, a fixed shaft connected to the mounting portion, a drive motor rotatably connected to the fixed shaft, and a plurality of fan blades fixed to the drive motor, wherein an anti-falling rope is connected to an upper end or a lower end of the fixed shaft, and a connection structure is provided between a lower end of the anti-falling rope and the fixed shaft to fixedly connect the lower end of the anti-falling rope and the fixed shaft, wherein an upper end of the anti-falling rope is fixed to the mounting portion or the wall. 
     
     
         2 . The fan with an anti-falling structure according to  claim 1 , wherein the fixed shaft is internally hollow to form a first through hole, and the fixed shaft comprises a first end portion provided at an upper end of the fixed shaft and extending above the drive motor or a second end portion provided at a lower end of the fixed shaft and extending below the drive motor, wherein the lower end of the anti-falling rope passes through the first through hole and is connected to the first end portion or the second end portion. 
     
     
         3 . The fan with an anti-falling structure according to  claim 2 , wherein the connection structure comprises a wire threading hole provided on the first end portion or the second end portion for the anti-falling rope to pass through, a wire sleeve provided on an exterior of the fixed shaft for the anti-falling rope to pass through, and a locking screw provided on the wire sleeve to lock the anti-falling rope inside the wire sleeve. 
     
     
         4 . The fan with an anti-falling structure according to  claim 3 , wherein the wire threading hole comprises a first wire threading hole provided on a side of the fixed shaft and a second wire threading hole provided on the fixed shaft opposite to the first wire threading hole. 
     
     
         5 . The fan with an anti-falling structure according to  claim 1 , wherein a connecting member is provided at the upper end of the anti-falling rope, and the connecting member comprises a connecting plate configured to be fixed to the mounting portion or the wall, wherein a fixing hole is provided on the connecting plate. 
     
     
         6 . The fan with an anti-falling structure according to  claim 2 , wherein a connection seat is provided between the fixed shaft and the mounting portion to connect the fixed shaft and the mounting portion, and a second through hole communicating with the first through hole is provided on the connection seat. 
     
     
         7 . The fan with an anti-falling structure according to  claim 6 , wherein the mounting portion comprises a ceiling base connected to the connection seat and fixed to the wall, and an interior of the ceiling base communicates with the second through hole. 
     
     
         8 . The fan with an anti-falling structure according to  claim 6 , wherein the mounting portion comprises a hanging rod connected to the connection seat and a ceiling suspension base fixed to the wall at an upper end of the hanging rod, wherein a third through hole is provided inside the hanging rod to communicate an interior of the ceiling suspension base with the second through hole. 
     
     
         9 . The fan with an anti-falling structure according to  claim 2 , wherein a light-emitting portion is connected to the second end portion, the light-emitting portion comprising a fixing plate arranged on the second end portion, a lampshade arranged on the fixing plate, and a lamp core arranged inside the lampshade, wherein the first through hole communicates with an interior of the lampshade. 
     
     
         10 . The fan with an anti-falling structure according to  claim 1 , wherein the anti-falling rope is a steel wire rope.
