Utility model content
The purpose of the utility model is to provide the small small machine fixed structures of a kind of vibration, noise.
The above-mentioned technical purpose of the utility model has the technical scheme that a kind of small machine fixed knot
Structure, including motor and back box, the motor are arranged in the back box, and the back box upper cover is equipped with cover board, go back in the back box
More connection bolts are equipped with, the connection bolt passes through the cover board and is threaded with fixture nut, the connection bolt
On be also socketed with damping cushion, and the motor is connected between each connection bolt and is connected on the damping cushion.
By using above scheme, motor is fixed by connecting bolt, connection bolt block the periphery of motor with
It is fixed, then damping cushion is set on connection bolt, avoid motor and connection bolt from directly contacting, avoid motor and connection
Bolt direct collision and issue huge noise, by the elastic reaction of damping cushion, so that motor is transmitted to connection when working
Vibration on bolt is reduced, to play the effect for reducing vibration, reducing noise.
The utility model is further arranged to: shock absorption strip, the two sides up and down of the shock absorption strip are also wound on the motor
It is pushed against respectively in the back box and the cover board.
By using above scheme, due to connecting the limit of bolt so that the surrounding of motor not with the surrounding side wall of back box
Contact, then shock absorption strip is wound in motor, avoid motor from directly contacting at work with the bottom surface of cover board or back box, thus further
Play the effect of damping noise reduction.
The utility model is further arranged to: after the shock absorption strip is wrapped on the motor, the shock absorption strip is connected to
The two sides of the back box and the cover board are plane.
By using above scheme, shock absorption strip is wrapped in the top and bottom on motor and is set as plane, is subtracted to increase
The contact area for shaking item and cover board, back box, to further increase damping noise reduction effect.
The utility model is further arranged to: filling block is additionally provided in the back box, the filling block is connected to described
Back box, the damping cushion and the shock absorption strip.
By using above scheme, filling block is set in back box, first is to absorb barrier noise, when reducing motor work
The noise being pierced by, second is the blank filled in back box, so that the part in back box is not easy at random, while enhancing back box side wall
Support strength.
The utility model is further arranged to: multiple through-holes are also distributed on the back box side wall.
By using above scheme, made a sound in the space that one seals, sound wave roundtrip will lead to noise
Increase, so through-hole is arranged on back box side wall, first is the cooling for facilitating air circulation in favor of motor, and second is reduction sound
Wave reflection is to reduce noise.
The utility model is further arranged to: one layer of silencing cotton is further fixed on the inner wall of the back box and the cover board.
By using above scheme, one layer of silencing cotton is set on the inner wall of back box and cover board, silencing cotton, which has to absorb, makes an uproar
The effect of sound, to further decrease noise when motor work.
In conclusion the utility model has the following beneficial effects: having reduces the vibration spread out of when motor work and makes an uproar
The effect of sound.
