Abstract
The utility model provides a kind of pipettor to interrupt, and comprises body of interrupting, and this body of interrupting is provided with the mounting groove of an indent, is provided with a sealing ring in this mounting groove, the outer surface of body of interrupting described in sealing circle protrudes from.The utility model pipettor is interrupted, and it is respectively arranged with sealing ring and position limiting convex ring, and sealing ring adopts elastomeric material to make, and only needs to adopt less power to install suction nozzle, and suction nozzle and form good sealing effectiveness between interrupting after installing, can not leakage.
Description
Technical field
The utility model relates to a kind of pipettor in medical testing equipment field, particularly relates to a kind of pipettor and interrupts.
Background technology
Biological various reaction all be unable to do without various solution.In these apertures, add various reaction solution is very basic and important work.All the time, biomedical worker relies on piston type charger to carry out the interpolation of various solution to microwell plate.
The piston/cylinder lower end of pipettor is provided with interrupts, and this is interrupted and to coordinate with suction nozzle, is drawn by reagent.In prior art, interrupt and often adopt hard material to make, and be generally column type, and suction nozzle adopts soft material to make, certain pressure is needed to get into the inwall of the suction nozzle conical surface by interrupting, allowing interrupts contacts and extrudes inner wall deformation, becomes and wrap fitting tightly in suction nozzle after distortion, forms sealing ring.But some suction nozzle materials are harder, or run into the very low suction nozzle of temperature hardening time, inserting power required in suction nozzle by interrupting will be very large, and, the place of interrupting with contact internal walls must be complete smooth circular arc, if because the burr that produces of processing problems, or the not high surface that causes of level of processing is smooth not, then easily cause and seal unsuccessfully, or increase the power required for sealing.
Utility model content
The purpose of this utility model is the defect overcoming prior art, provides a kind of pipettor being easy to seal to interrupt, only needs less power this can be interrupted and insert in suction nozzle.
For achieving the above object, the utility model provides a kind of pipettor to interrupt, and comprises body of interrupting, and this body of interrupting is provided with the mounting groove of an indent, is provided with a sealing ring in this mounting groove, the outer surface of body of interrupting described in sealing circle protrudes from.
Further, this mounting groove is annular recess.
Further, described sealing ring is made up of elastomeric material.
Further, described sealing ring is made up of rubber.
Further, described sealing ring is O type circle.
Further, described sealing ring protrudes from the height of the part of body of interrupting is 1/5th of its wire diameter.
Further, described in interrupt on body and be also provided with position limiting convex ring, this position limiting convex ring is positioned at the side of described mounting groove away from mouth of interrupting.
Further, described position limiting convex ring is arc bulge loop, is formed by described body of interrupting is outwardly.
The beneficial effects of the utility model: the utility model pipettor is interrupted, be respectively arranged with sealing ring and position limiting convex ring, sealing ring adopts elastomeric material to make, and only needs to adopt less power to install suction nozzle, and suction nozzle and form good sealing effectiveness between interrupting after installing, can not leakage.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model pipettor is interrupted.
Detailed description of the invention
Mechanism of the present utility model and operation principle is described in detail below in conjunction with accompanying drawing.In order to better the present embodiment is described, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; To those skilled in the art, in accompanying drawing, some known features and explanation thereof may be omitted is understandable.The corresponding same or analogous parts of same or analogous label.
Shown in Figure 1, the utility model provides a kind of pipettor to interrupt, comprise body 10 of interrupting, this body 10 of interrupting is provided with the mounting groove 11 of an indent, this mounting groove 11 is annular recess, be provided with a sealing ring 12 in this mounting groove 11, the outer surface of body 10 of interrupting described in sealing circle 12 protrudes from, this mounting groove 11 is near mouth 14 position of interrupting.When suction nozzle is installed, only needs to apply less power and can interrupt and insert in suction nozzle, and sealing ring 12 and suction nozzle are formed and seal.Described sealing ring 12 is made up of elastomeric material, further, is made up of rubber, has good elasticity, thus forms good sealing effectiveness with suction nozzle after extrusion.Described sealing ring 12 is O type circle, its height protruding from the part of body 10 of interrupting is 1/5th of its wire diameter, can guarantee that sealing ring 12 by too large pressure and can not involve power, when unloading suction nozzle, sealing circle 12 is not easily driven by suction nozzle and comes off from mounting groove 11.
Further, described in interrupt on body 10 and be also provided with position limiting convex ring 13, this position limiting convex ring 13 is positioned at the side of described mounting groove 11 away from mouth 14 of interrupting.Described position limiting convex ring 13 is arc bulge loop, interrupts that body 10 is outwardly to be formed by described.This position limiting convex ring 13 limits the degree of depth inserting suction nozzle of interrupting, and prevents sealing ring 12 by excessive compression.During the outer diameter contact suction nozzle inwall of position limiting convex ring 13; described sealing ring 12 has obtained fully compression and has formed good sealing effectiveness; the contact surface of this position limiting convex ring 13 and suction nozzle increases suction nozzle and kinetic friction force between interrupting; cause interrupt to suction cephalomotor static, and then protection sealing ring 12 be further compressed.
The utility model pipettor is interrupted, and it is respectively arranged with sealing ring and position limiting convex ring, and sealing ring adopts elastomeric material to make, and only needs to adopt less power to install suction nozzle, and suction nozzle and form good sealing effectiveness between interrupting after installing, can not leakage.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in the utility model claim.
