Abstract
The invention provides a leakage-proof rotor block, which comprises a base, a shelving platform and a sealing fixed device, wherein a fixed device is arranged in the center of the base, and the base is connected with a rotating shaft through the fixed device; the shelving platform is arranged on the base; and the sealing fixed device is arranged at the outer side of the upper part of the shelving platform, and a sealing ring is arranged in the sealing fixed device. The cross section of the sealing fixed device is an irregular polygon, and an opening is formed at one side of the sealing fixed device close to the fixed device; and a baffle plate is arranged at the opening, and the shape of the area encircled by the baffle plate and the sealing fixed device is matched with the sealing ring. According to the leakage-proof rotor block, the sealing fixed device is arranged on the base, the sealing ring is put into the sealing fixed device, and the original mode of arranging the sealing ring on a rotor cover is changed, so that continuous drop is not produced due to repeated opening of the rotary cover in use; and a protrusion arranged in an inner ring can play a good role in buffering and sealing.
Description
Technical field
The present invention relates to a kind of rotor, particularly a kind of leakproof rotor block that is used for centrifuge.
Background technology
No matter medical treatment, pharmacy relevant industries are non-sterile environment of requirement or gnotobasis with centrifuge; In its use very high requirement has been proposed environment requirement; Under high-grade environmental requirement; Such as in sterile workshop, workshops such as ten thousand grades, 100,000 grades are just arranged, good airtight performance can make outside isolation of remaining valid with machine intimate.Solid, liquid, gas in the centrifuge rotor must not produce cross pollution with operating personnel, external environment condition mutually.
And more common at present sealed fixing device is to cover at centrifuge rotor the RUBBER O RunddichtringO is housed, because sealing ring is mounted on the rotor cover, is to install downwards, is easy to cause coming off of sealing ring.
Summary of the invention
The object of the present invention is to provide a kind of with sealed fixing device place on the rotor block, sealing ring is easy for installation and can prolong the sealing ring leakproof rotor block in service life.
Leakproof rotor block of the present invention comprises: base, be provided with fixture at the center of said base, and said base is connected with rotating shaft through said fixture; Articles holding table is arranged on the said base; Sealed fixing device is arranged on the upper outer of said articles holding table, is provided with sealing ring in the said sealed fixing device.
The cross section of said sealed fixing device is irregular polygon, is provided with opening at said sealed fixing device near a side of said fixture; Be provided with baffle plate at said opening part, the shape and the said sealing ring in the zone that itself and said sealed fixing device surround agree with.
Leakproof rotor block of the present invention is provided with sealed fixing device on base; Sealing ring is put in its inside again; Changed original shape sealing ring has been arranged on the mode on the rotor cover; Make the position of the sealing ring relative fixed that just becomes, can be owing to rotor cover opening repeatedly in use do not caused the phenomenon that constantly comes off, and also the projection that is arranged on inner ring can open the effect of good buffering and sealing.

The specific embodiment
Below in conjunction with accompanying drawing leakproof rotor block of the present invention is done further explain.
The cross section of sealed fixing device 4 is irregular polygon, is provided with opening at sealed fixing device 4 near a side of fixture 2;
Be provided with baffle plate 6 at opening part, baffle plate 6 is flexible connection with articles holding table 3, adopts the mode of hinge 7 to fix, and baffle plate 6 can let sealing ring install or remove from sealed fixing device 4 freely towards the center upset of leakproof rotor block like this.The inboard of baffle plate 6 is designed to agree with sealing ring projection 9 profiles, and shape and the sealing ring 5 in the zone that surrounds of baffle plate 6 and sealed fixing device 4 agree with, and so just can carry out well fixing to sealing ring 5.
The cross section of sealed fixing device 4 is irregular polygon, is provided with opening at sealed fixing device 4 near a side of fixture 2;
Be provided with baffle plate 6 at opening part, baffle plate 6 is flexible connection with articles holding table 3, adopts the mode of slide rail 8 to fix, and baffle plate 6 can move in certain amplitude along slide rail, can let sealing ring install or remove from sealed fixing device 4 freely like this.The inboard of baffle plate 6 is designed to agree with sealing ring projection 9 profiles, and shape and the sealing ring 5 in the zone that surrounds of baffle plate 6 and sealed fixing device 4 agree with, and so just can carry out well fixing to sealing ring 5.
During use, earlier sealing ring 5 is encased in sealed fixing device 4, sealing ring 4 is fixed; Then rotor cover 11 is pressed into, sealing ring projection 10 is omited upper bottom surface high and baffle plate 6, like this when rotor cover 11 lids are gone into rotor block; Rotor cover 11 can touch sealing ring projection 10 earlier; Because sealing ring projection 10 is the elastomeric materials that adopt, when O-ring seals 9 did not also touch articles holding table 3, sealing ring projection 10 can play the effect of buffering; Also touch articles holding table 3 until O-ring seals 9, accomplish the work of sealing.
Leakproof rotor block of the present invention is provided with sealed fixing device on base; Sealing ring is put in its inside again; Changed original shape sealing ring has been arranged on the mode on the rotor cover; Make the position of the sealing ring relative fixed that just becomes, can be owing to rotor cover opening repeatedly in use do not caused the phenomenon that constantly comes off, and also the projection that is arranged on inner ring can open the effect of good buffering and sealing.
Below the preferred embodiment of the invention is specified; But the invention is not limited to said embodiment; Those of ordinary skill in the art also can make all modification that is equal to or replacement under the prerequisite of the invention spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
