When base and dryer are connected, still with the beaded finish is connected, so, when dryer itself obtains reinforceing, the dryer also obtains reinforceing with being connected of base, and the beaded finish has constituted the reinforced structure of fan with the cooperation of dryer, base. The motor and the fan blade are arranged in the strengthening structure, and the complete fan is formed.
The reinforced structure can improve the compressive strength of the fan and the stability of the fan structure.

Detailed Description
With reference to fig. 1 and 2, the fan reinforcing structure includes a wind barrel 10 and a base 20, a reinforcing ring 30 is installed on the inner side wall of the wind barrel, the reinforcing ring is installed on the wind barrel through a threaded connector 41, and the threaded connector penetrates through the wind barrel and is connected with the base.
The reinforcing ring 30 is tightly supported in the air duct 10 to reinforce the compression strength of the air duct. The base 20 is connected with the reinforcing ring 30 and the air duct 10 by the threaded connector 41, that is, the reinforcing ring, the air duct and the base are connected by the threaded connector 41.
The reinforcing ring 30 is provided with a notch 31, two ends of the notch are respectively provided with a connecting part 33, the two connecting parts are connected through a connecting part, and the connecting part can enable the two connecting parts to be far away; the reinforcing ring 30 is provided with two first connecting hole sites 32 located at both sides of the opening, the air duct 10 is provided with two second connecting hole sites 11 corresponding to the two first connecting hole sites one by one, and the base 20 is provided with two third connecting hole sites 21 corresponding to the two first connecting hole sites one by one.
The structural design of the reinforcement ring 30 is specifically described herein. The gap 31 allows the diameter of the reinforcement ring 30 to be increased or decreased. When the wind barrel is installed, an operator presses the reinforcing ring towards the circle center direction of the reinforcing ring to reduce the diameter of the reinforcing ring, and then the reinforcing ring is placed into the wind barrel 10. A first connection hole site 32 is aligned with a second connection hole site 11 and a third connection hole site 21, and a threaded connector 41 is threaded through the first connection hole site and the second connection hole site to be screwed with the third connection hole site. At this time, since the fitting of the reinforcing ring 30 and the air duct 10 is relatively loose, the other first connection hole site 32 is not aligned with the other second connection hole site 11 and the other third connection hole site 21. For this purpose, the operator moves the connecting elements to move the two connecting portions 33 away from each other, and the reinforcement ring 30 is expanded and tightened in the air duct 10, while the further first connecting hole site is aligned with the further second connecting hole site and the further third connecting hole site. And the operator penetrates another threaded connecting piece through the other first connecting hole position and the other second connecting hole position to be in threaded connection with the other third connecting hole position. Therefore, when the reinforcing ring 30 reinforces the air duct 10, the stability of the reinforcing ring is improved, and then the reinforcing ring is connected with the base 20, so that the stability of the connection relationship between the base and the air duct is enhanced.
Alternatively, the connecting element is a screw 34, which is essentially a threaded connection that is screwed onto one of the two connecting parts 33 and pressed against the other. And (4) screwing the jackscrew by using a screwdriver, and opening the two connecting parts by using the jackscrew.
The outer diameter of the reinforcing ring 30 is equal to or greater than the inner diameter of the air duct 10. The outer diameter of the reinforcement ring, in particular if there is no gap 31, is a circular ring, the outer diameter of which is the outer diameter of said reinforcement ring. The reinforcement ring with the notch 31 has a size that is variable, so that the periphery or the inner ring of the reinforcement ring is not a standard circle when the size of the notch changes. The outer diameter of the reinforcing ring 30 is equal to the inner diameter of the air duct 10, the outer side wall of the reinforcing ring can be in close contact with the inner side wall of the cylindrical air duct comprehensively, the strength of the air duct is improved comprehensively, the notch 31 is located below the two first connecting hole positions 32, and the strength soft rib of the air duct at the notch 31 is filled by the base 20. The external diameter of beaded finish 30 is greater than the internal diameter of dryer 10, and under the effect of jackscrew 34, the beaded finish props tightly on the dryer inside wall, and later, continues to twist the jackscrew, and the beaded finish can take place elastic deformation, and after two threaded connection 41 all installed in place, the elastic deformation of beaded finish was kept, and elastic deformation's effort acts on the dryer inside wall, and this is favorable to preventing the deformation that dryer 10 probably produced in the use.
The number of the reinforcing rings 30 is at least two, and all the reinforcing rings are distributed along the axial direction of the air duct 10. For example, the number of the reinforcing rings is two, and the reinforcing rings are distributed at the front and rear ends of the air duct 10.
The reinforcing ring 30 of the present invention belongs to an external part of a fan, which does not damage the original structure of the fan, and only holes are punched at the corresponding positions of the air duct 10 and the base 20, namely the second connecting hole 11 and the third connecting hole 21, wherein the third connecting hole is a threaded hole. However, the overall structure of the fan becomes stable, and the deformation resistance of the air duct is enhanced.
The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description herein, since various changes and modifications can be made in the details of the embodiment and the application range according to the spirit of the present invention.
