Compared with the prior art, the damping denoising device of the domestic oxygenator, which is disclosed by the utility model, reduces the vibration of the compressor and the noise, and meanwhile is beneficial to radiating.
Description
Technical field
The utility model relates to the oxygenerator field of medical instruments field, relates in particular to a kind of Domestic oxygen erator shock-absorbing denoising device.
Background technique
A vitals of Domestic oxygen erator is Miniature oil-free air compressor, and oxygenerator produces aerodynamic noise, mechanical vibration noise and the formation of motor rotational noise that the main cause of noise is compressor, therefore, to Domestic oxygen erator noise reduction, be importance to the damping noise reduction of compressor.
In prior art, between general shock-proof spring and compressor leg, be screwed, the other end and the chassis base of spring are screwed, by this spring structure, compressor is fixed on chassis base, both ends of the spring means of fixation causes compressor in use because center and the chassis base fixed hole center of compressor seat leg are difficult to accomplish there is no deviation, centre deviation tends to cause compressor sideshake, thereby has reduced noise reduction, and noise reduction is undesirable.
Model utility content
The utility model has overcome the deficiencies in the prior art, and a kind of Domestic oxygen erator damped noise reduction device that is conducive to compressor center balance is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of Domestic oxygen erator damped noise reduction device, between compressor in oxygenerator and chassis base, be provided with damping spring, the bottom surface of compressor is provided with the first rubber pad, the upper surface of chassis base is provided with the second rubber pad, the central position of described the first rubber pad is provided with cylindrical cavity, described cylindrical cavity top closure, the central position of described the second rubber pad is provided with through hole, and the two ends of described damping spring are embedded into respectively in described cylindrical cavity and through hole.
Chassis base is provided with tapped hole, in described tapped hole, be provided with the caging bolt adapting with described tapped hole, the screw rod of described caging bolt is through described through hole and damping spring, the top of described screw rod extend in the cylindrical cavity of described the first rubber 4, and and the chamber wall of cylindrical cavity between leave gap.
The middle part of chassis base is fixedly installed horizontal anchor ear and longitudinal anchor ear by screw, and compressor is arranged on described horizontal anchor ear and longitudinally in anchor ear, and and described horizontal anchor ear and longitudinally all leave gap between anchor ear.
Laterally the internal surface of anchor ear and longitudinal anchor ear is provided with rubber layer, and compressor is subjected to displacement, and touches horizontal anchor ear and longitudinal anchor ear, and rubber layer can effectively be protected compressor collsion damage.
The quantity of the first rubber pad is 4, and described the first rubber pad is symmetricly set on the bottom surface of compressor.
Compared with prior art, the beneficial effects of the utility model have:
First, the utility model compressor and damping spring end points are unfixing, and compressor can hang and be sitting on damping spring, reduce the in use center of compressor seat leg and the deviation of the fixing damping spring place-centric of chassis base of compressor, reduce the vibration of compressor, reduce noise.
Further, the horizontal anchor ear of the utility model and longitudinally anchor ear setting, prevent that oxygenerator is in transportation process, and the displacement of compressor is excessive, in using process, and protection compressor, meanwhile, compressor and laterally anchor ear and the longitudinally gap between anchor ear, be conducive to heat radiation.
