Description
Technical field
The present invention relates to a kind of pipettor in biology and medical treatment test, inspection apparatus field, more particularly to a kind of liquid relief
Device is interrupted.
Background technology
Microwell plate, including the form such as single hole, 8 holes, 96 holes and 384 holes, be in bioengineering and medical test commonly use it is anti-
Answer container.There are many apertures above by it, many test samples can be loaded and reacted under the same conditions, therefore in life
It is used widely in the research and application of thing and medical science.
The various reactions of biology all be unable to do without various solution.It is unusual base that various reaction solutions are added into these apertures
Plinth and important work.All the time, it is various molten to microwell plate progress to depend on piston type charger by biomedical worker
The addition of liquid.
The piston cylinder lower end of pipettor, which is provided with, interrupts, and this is interrupted coordinates with suction nozzle, and original solution is inhaled in original solution box
Take up.In the prior art, interrupt often adds two bulge loops to position and seal or using cylindrical using cylindrical
A rigid bulge loop and a sealing ring is added to position and seal.Two kinds of effects are all bad, if adding two using cylinder type
Bulge loop, it is a round wires that bulge loop engages with suction nozzle, is all rough on all objects surface microscopic, so causing sealing to imitate
Fruit is bad, easily causes leakage；If adding a rigid bulge loop and a sealing ring using cylinder type, repeatedly it is seated and takes off suction
After head, ring wear is even broken and dropped, and influences the interrupt durability and stability of sealing.
The content of the invention
The defects of it is an object of the invention to overcome prior art, there is provided one kind be easy to sealing, it is durable and processing again it is simple
Interrupt.
To achieve the above object, the present invention provides a kind of pipettor and interrupted, including body of interrupting, and is set on the body of interrupting
It is equipped with sealing cone.
The sealing cone taper is consistent with liquid-transfering sucker inwall taper.
The length of the sealing cone lower part is 0.2mm~0.3mm.
The length that the sealing cone upper part contacts with suction nozzle is 0.3mm~0.5mm.
The concave surface that sealing cone is separated into two top and the bottom is provided with the body of interrupting.
The concave surface and body height of interrupting are more than 0.02mm.
Body of being interrupted described in institute is made of rigid material.
Body of interrupting, sealing cone and the concave surface, which are formed in one, to be made.
Beneficial effects of the present invention：Pipettor of the present invention is interrupted, and is made of rigid material, is respectively arranged with sealing thereon
The conical surface and concave surface, are easily installed suction nozzle；The scheme of two convex ring for sealing is relatively provided with, of the invention interrupting is engaged more with suction nozzle contact surface
It is good, that is, better tightness；It is more economical durable compared with the scheme of a rigid bulge loop and labour sealing ring, of the invention interrupting；
Because the sealing cone taper of interrupting of the present invention is consistent with liquid-transfering sucker inwall taper, interrupts and engaged with suction nozzle contact surface more preferably,
Natural guidance quality is also more preferable, is ensured well so being seated rear suction nozzle direction.
Brief description of the drawings
Fig. 1 is the dimensional structure diagram that pipettor of the present invention is interrupted；
Fig. 2 is the partial sectional view that pipettor of the present invention is interrupted.
Embodiment
The mechanism and operation principle that the invention will now be described in detail with reference to the accompanying drawings.In order to more preferably illustrate the present embodiment, accompanying drawing
Some parts have omission, zoomed in or out, and do not represent the size of actual product；To those skilled in the art, it is attached
Some known features and its explanation may be omitted and will be understood by figure.Same or analogous label corresponds to same or analogous
Part.
Referring to shown in Fig. 1-2, the present invention provides a kind of pipettor and interrupted, including body 1 of interrupting, described to interrupt on body 1
It is provided with sealing cone 3.The body 1 of interrupting is made of rigid material, is had rigidity, is reached durable effect.The sealing
The taper of the conical surface 3 is consistent with liquid-transfering sucker inwall taper, and it is smaller with the contact area of suction nozzle but very close, is easy to deep insertion and inhales
In head, sealing effectiveness is preferable.To sealing large effect, concave surface 2 should be ensured that sealing cone 3 for the position of concave surface 2 and length
The length of lower part is 0.2mm~0.3mm, and the length that the upper part of sealing cone 3 contacts with suction nozzle is 0.3mm~0.5mm；If
The length that the upper and lower part of sealing cone 3 contacts with suction nozzle is excessive, and it is not big enough to act on the unit pressure of suction nozzle inwall, suction nozzle modeling
Property deflection is inadequate, and sealing effectiveness is with regard to bad；If the length that the upper and lower part of sealing cone 3 contacts with suction nozzle is too small, sealing surface
Product is not big enough, and sealing effectiveness is also bad.Preferably, the length of the lower part of sealing cone 3 is 0.2mm~0.3mm, described close
The length that the envelope upper part of the conical surface 3 contacts with suction nozzle is 0.3mm~0.5mm, so can guarantee that good sealing effectiveness.
Further, sealing cone 3 is additionally provided with the body 1 of interrupting, the sealing cone 3 is divided to be upper by concave surface 2
Lower two parts.The taper of sealing cone 3 is consistent with liquid-transfering sucker inwall taper, the conical surface of sealing cone 3 well with suction
Head inwall fitting, is restricted the angle that suction nozzle is swung, so as to be oriented to suction nozzle to ensure suction nozzle straight down, and it is described close
The envelope conical surface 3 has the splendid sealing effectiveness engaged with suction nozzle inwall.The length of the lower part of sealing cone 3 be 0.2mm~
0.3mm, the length that the upper part of sealing cone 3 contacts with suction nozzle are 0.3mm~0.5mm.
Body 1 of interrupting, the concave surface 2 and the sealing cone 3 are formed in one and are made, easy to process, ensure processing essence
Density.
Pipettor of the present invention is interrupted, and is made of rigid material, is respectively arranged with concave surface and sealing cone thereon, is easy to pacify
Fill suction nozzle, and suction nozzle and sealing is good between interrupting after installing, will not leakage, and direction is guaranteed.
Obviously, the above embodiment of the present invention is only intended to clearly illustrate example of the present invention, and is not pair
The restriction of embodiments of the present invention.For those of ordinary skill in the field, may be used also on the basis of the above description
To make other changes in different forms.There is no necessity and possibility to exhaust all the enbodiments.It is all this
All any modification, equivalent and improvement made within the spirit and principle of invention etc., should be included in the claims in the present invention
Protection domain within.
