Abstract
The utility model discloses a kind of potted component of centrifugal machine door cover, including the Ji Quan provided with bayonet socket, the sealing ring that is located on Ji Quan, the sealing ring include the circle body provided with hollow molded cavity, are located at the annular lip of circle body upper surface.The utility model is when the door closure of centrifuge is closed, lip is collectively forming the air current sealed of centrifugal chamber under the compressing of door closure with door closure, because lip can be bent therefore smaller to the reaction force of door closure, door closure pressure need not it is very big in the case of, achieve that the effective sealing of centrifugal chamber, and the stress of door closure lock is also smaller, door closure is easily closed and opened.When centrifuge works, as centrifugation cavity pressure increases, lip can be propped up therewith, and the bigger lip of air pressure is bonded closer with door closure, and sealing effectiveness is better, and the pressure of centrifugal chamber is reduced after centrifugation terminates, and sealing effectiveness is not directly affected by door closure pressure.
Description
Technical field
The utility model belongs to laboratory centrifuge, and in particular to a kind of potted component of centrifugal machine door cover.
Background technology
Centrifuge is that rotation produces powerful centrifugal force at a high speed using rotary head, carrys out the sinking speed of particle in accelerating liquid,
The instrument that the material of different sedimentation coefficients and buoyant density in sample is separated.It is widely used in life science, medical science, change
The fields such as, environmental protection.
The sealing structure of centrifuge is one of key components of centrifuge, centrifuge in normal centrifugal work due to
Rotor high speed rotation can produce powerful centrifugal force so that larger gas pressure is formed in centrifugal chamber, due to tradition from
Scheming is that door closure is directly born against above centrifugal chamber, and potted component is hollow semi-circular shape, to realize and centrifugal chamber is fully sealed
Door closure crush seal circle must be leaned on to complete the sealing of centrifugal chamber, its pressure to sealing ring have to be larger than centrifugal chamber when door closure is closed
Interior air pressure can be only achieved the purpose to centrifugal chamber sealing, and it is due to reaction of the door closure by sealing ring to bring the problem of new therewith
Power is easily deformed greatly very much, while the stress of door closure lock is also just very big, and causes door closure to close and open difficulty, so that operation makes
With very inconvenient.In addition, when centrifugation cavity pressure exceedes its seal pressure, it may appear that leak out and fly along with liquid or reagent
Spill centrifugal chamber.Due to centrifuge be apply medical treatment and laboratory environment, its centrifuge object may Carried bacteria, virus or its
Its harmful substance.When these harmful substances are sputtered centrifugal chamber, it is possible to centrifuge operations personnel or experimenter
Health damages.
Utility model content
The purpose of this utility model is to provide a kind of potted component of the centrifugal machine door cover of good sealing effect.
Realize that the technical scheme that the utility model purpose uses is as follows：
The potted component of centrifugal machine door cover provided by the utility model, including the Ji Quan provided with bayonet socket, be located on Ji Quan
Sealing ring, the sealing ring include the circle body provided with hollow molded cavity, are located at the annular lip of circle body upper surface.
The Ji Quan uses a kind of material, and the sealing ring is using another material softer than the base loop material.
The lip slopes inwardly.
The lip is two layers.
The Ji Quan is provided with outer bayonet and inner bayonet or provided with inner bayonet, and Ji Quan bottom is provided with back-up ring, described interior
Bayonet socket is located at the outside of back-up ring.
The beneficial effects of the utility model
1st, the utility model is fixed on the centrifugal chamber edge of opening of centrifuge by the bayonet socket on Ji Quan, the door of centrifuge
When lid is closed, lip is collectively forming the air current sealed of centrifugal chamber under the compressing of door closure with door closure, because lip can bend event
It is smaller to the reaction force of door closure, door closure pressure need not it is very big in the case of, so that it may realize the effective sealing of centrifugal chamber,
And the stress of door closure lock is also smaller, door closure is easily closed and opened.
2nd, when centrifuge works, as centrifugation cavity pressure increases, lip can be propped up therewith, the bigger lip of air pressure and door closure
It is bonded closer, sealing effectiveness is better, and the pressure of centrifugal chamber reduces after centrifugation terminates, and sealing effectiveness is not by door closure pressure
Directly affect.
3rd, can effectively prevent from leaking out going out centrifugal chamber with substance splash such as liquid or reagents, avoiding may be to centrifuge operations
Personnel or experimenter damage, and play more effective safety protection function.
The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings.

Embodiment
Embodiment 1
See Fig. 1, centrifuge includes door closure 1, potted component 2, casing cover plate 3, centrifugation frame 4, protective case 5, centrifugal chamber 6,
Rotor 7, bottom sealing ring 8 and motor 9；The potted component 2 of centrifugal machine door cover provided by the utility model, as shown in figure 3,
Including base circle 202 and the sealing ring 201 being located above base circle 202, the sealing ring 201 includes the circle provided with hollow molded cavity 2014
Body 2013, it is located at two layers of lip of lip 2012 and outer lip 2011 in the intilted annular in the upper surface of circle body 2013；The base
Circle 202 is provided with outer bayonet 2021 and inner bayonet 2022, and the bottom of base circle 202 is provided with back-up ring 2023, and inner bayonet 2022 is located at gear
