The existing fan is not provided with a silencing and damping mechanism, and only needs to be adjusted according to the size of wind power, so that the defects that: violent vibrations can cause wearing and tearing to fan itself, reduces the life of fan, increases the manufacturing cost of enterprise, and the antidetonation effect is not good, and the problem of noise is not solved moreover.
SUMMERY OF THE UTILITY MODEL
The utility model aims at: the utility model provides a shock attenuation amortization mechanism of fan effectively improves antidetonation effect, and the noise abatement reduces vibrations and to the wearing and tearing that the fan produced, increases the life of fan, improvement manufacturing cost.
In order to achieve the above object, the present invention provides the following technical solutions:
the utility model provides an amortization damper of fan, includes fixed disk, connecting axle, rotary disk, motor, fixed disk and connecting axle one end threaded connection, be equipped with the rectification blade on the fixed disk, be equipped with the shock attenuation strip of pasting on the rectification blade, rotary disk and connecting axle swing joint, be equipped with guide vane on the rotary disk, the last amortization paster that is equipped with of guide vane, motor and fixed disk fixed connection, the pivot of motor runs through the fixed disk and with connecting axle fixed connection.
Preferably, the number of shock attenuation welt is a plurality of, specifically is the rectangle, and the shock attenuation welt is evenly arranged on the rectification blade, the shock attenuation welt is made for butyl rubber material.
Preferably, the number of the noise reduction patches is a plurality of, specifically block-shaped, and the noise reduction patches are arrayed on the guide vane, and the noise reduction patches are made of a foam noise reduction material.
Preferably, the fixed disc is the same as the rotating disc in size, and the shape and size of the rectifying blades are consistent with those of the guide vanes.
Preferably, the two ends of the fixed disc connected with the connecting shaft are both provided with positioning blocks.
The utility model has the advantages that: the utility model provides a shock attenuation amortization mechanism of fan, can effectively improve antidetonation effect, the noise reduction reduces vibrations and to the wearing and tearing that the fan produced, increases the life of fan, improvement manufacturing cost.

Fig. 1 is the utility model relates to a amortization damper's of fan overall structure sketch map.
In the figure: 1. fixing the disc; 10. a rectifying blade; 100. damping adhesive strips; 2. a connecting shaft; 3. rotating the disc; 30. a guide vane; 300. a noise reduction patch; 4. a motor; 5. and (5) positioning the blocks.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Referring to fig. 1, a amortization damper of fan, including fixed disk 1, connecting axle 2, rotary disk 3, motor 4, fixed disk 1 and 2 one end threaded connection of connecting axle, be equipped with rectification blade 10 on the fixed disk 1, be equipped with the shock attenuation on the rectification blade 10 and paste strip 100, rotary disk 3 and 2 swing joint of connecting axle, be equipped with guide vane 30 on the rotary disk 3, be equipped with amortization paster 300 on the guide vane 30, motor 4 and 1 fixed connection of fixed disk, the pivot of motor 4 runs through fixed disk 1 and with 2 fixed connection of connecting axle.
The number of the shock absorption strips 100 is a plurality of, specifically rectangular, and the shock absorption strips 100 are evenly arranged on the rectifying blades 10, the shock absorption strips 100 are made of butyl rubber materials, and the shock absorption strips 100 are used for shock absorption.
The number of amortization paster 300 is a plurality of, specifically is cubic, and array in guide vane 30 is last, amortization paster 300 is foam noise reduction material, thereby amortization paster 300 is used for inhaling the sound and reaches noise cancelling effect.
The size of the fixed disc 1 is the same as that of the rotating disc 3, the size of the rectifying blades 10 is consistent with that of the guide vanes 30, the rotating disc 3 is used for dynamic noise reduction, the noise reduction effect can be greatly enhanced, the rectifying blades 10 can rectify wind entering the air inlet chamber, the guide vanes 30 can achieve the guiding effect, and the wind in the fan can be maximally utilized due to the arrangement.
