Abstract
The invention discloses a shock-absorption and noise-reduction device of a domestic oxygenerator. Shock absorption springs (3) are arranged between a compressor (1) in the oxygenerator and a machine case base (2), first rubber mats (4) are arranged on the bottom surface of the compressor (1), second rubber mats (5) are arranged on the upper surface of the machine case base (2), the two ends of the shock absorption springs (3) are embedded into cylindrical cavities (401) of the first rubber mats (4) and through holes of the second rubber mats (5) respectively, threaded rods (601) of limiting bolts (6) penetrate through the through holes and the shock absorption springs (3), the top ends of the threaded rods (601) are inserted into the cylindrical cavities (401) of the first rubber mats (4), and gaps are reserved between the threaded rods (601) and the cavity walls of the cylindrical cavities (401). Compared with the prior art, the shock-absorption and noise-reduction device has the advantages that shock of the compressor is reduced, noise is lowered, and meanwhile radiating is facilitated.
Description
Technical field
The present invention relates to the oxygenerator field of medical instruments field, relate in particular to a kind of Domestic oxygen erator damped noise reduction 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, to the damping noise reduction of compressor, be importance.
In prior art, between general damping 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.
Summary of the invention
The present invention 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 used in the present invention 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, beneficial effect of the present invention has:
First, compressor of the present invention and damping spring end face are fixing, and compressor can be suspended on damping spring completely, reduce the in use fixing deviation of damping spring place-centric of the center of compressor seat leg and chassis base of compressor, reduce the vibration of compressor, reduce noise.
Further, the horizontal anchor ear of the present invention 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.
