Disclosure of Invention
The utility model aims at the above-mentioned problem that prior art exists, provide a fan damping mechanism that compact structure stability is strong.
The purpose of the utility model can be realized by the following technical proposal:
the utility model provides a damping mechanism of fan, the fan includes cylindric casing, its characterized in that, this damping mechanism includes shock attenuation post, support and base, the base be the rectangle and set up in the casing lower part, the support be rectangular form and transversely set up on base upper portion, the shock attenuation post connect between support and base, the shock attenuation post includes sleeve, loop bar, damping spring and supporting spring, above-mentioned sleeve upper end links firmly with the support, above-mentioned loop bar lower extreme links firmly with the base, above-mentioned loop bar upper end inlays in the sleeve and loop bar upper portion is equipped with damping spring, above-mentioned damping spring fixes inside the sleeve, above-mentioned supporting spring is fixed to be set up in the loop bar lower part.
In the fan vibration damping mechanism, threaded holes are further formed in two ends of the side portion of the base, and bolts are connected in the threaded holes in a threaded mode.
Can be fixed in subaerial with the base steady through screw hole and the bolt on the base, easy dismounting, simple structure uses extensively.
The upper end of the loop bar is embedded in the sleeve, and the loop bar and the sleeve are movably connected. That is, the sleeve can move up and down relative to the stem.
In the initial state, the support can move upwards under the action of the damping spring and the supporting spring, and the spring is always in a stressed state.
The vibration of the fan generated in the running process is absorbed by the damping spring and the supporting spring, so that the vibration can be properly absorbed, and the rigid contact between the fan and the base is avoided. The stability of the product is effectively improved.
In the above fan damping mechanism, the damping columns are four groups and are arranged at the corners of the base.
The setting of many balancing columns can further reinforcing base and the support between be connected stability.
In the above-mentioned fan damping mechanism, the housing is fixedly connected with the bracket.
Simple structure, reliable positioning and can bear larger axial force.
In the fan vibration reduction mechanism, the number of the two supports is two, and the two supports are fixedly connected through the connecting rod.
The setting of connecting rod can effectual support and fixed bolster to make the support can not take place the distortion when bearing pressure, simple structure, connection rigidity is big, and the atress is even.
Compared with the prior art, this fan damping mechanism, the wholeness is good, and inside this damping mechanism was fixed in to the fan is firm, and bearing capacity is strong, effectively improves its damping effect through the shock attenuation post of equipartition, can bear great load, and sleeve and loop bar have very high precision, long service life.
Moreover, the shock absorption column has a large load range, is strong in adaptability to the working environment, is not easy to age, prolongs the shock absorption service life, can meet the existing working condition, and is good in shock absorption effect and convenient to install.
