Abstract
The utility model provides a novel sucker with a seal line. The novel sucker comprises a sucker body, wherein the lower end of the sucker body is used for sucking liquid, the upper end of the sucker body is connected with a pipette, a reinforcing rib in vertical direction is arranged on the upper end of the outer surface of the sucker body, scale lines for measuring the volume of liquid in the sucker body are arranged on the lower end of the outer surface of the sucker body, and at least one seal line along with the circumference direction is arranged on the upper end of the inner surface of the sucker body. By virtue of the scheme, the seal line in the circumference direction is arranged on the upper end of the inner surface of the sucker body, so that when the tip of the pipette is matched with the sucker, the complete sealing effect can be achieved by virtue of the extrusion of the seal line; the sucker can be adaptive to different sizes of pipette tips, so that the falling phenomenon caused due to non-tight matching of the sucker and the pipette tip can be prevented, and the novel sucker is simple in structure and easy to manufacture.
Description
Technical field
The utility model relates to laboratory apparatus field, refers to especially a kind of suction nozzle of Novel belt potted line.
Background technology
At present, the suction pipette head that sell in market is mainly the tubular article of the hollow made with polythene material, and for being arranged on pipettor, the air pressure that relies on pipettor to produce sucks and discharge liquid.According to pipettor model, pipette liquid maximum volume at every turn, suction nozzle used varies in size, and common are 50000 microlitres, 1000 microlitres, 200 microlitres, several specifications such as 10 microlitres.But the inner chamber of existing its carrying liquid of suction nozzle directly contacts with pipettor, and the rifle area of bed tolerance of the pipettor of different brands is inconsistent, and rifle head has untight situation of cooperation while being connected with the suction nozzle of standard, thereby causes suction nozzle to come off, and causes the failure of an experiment.And the liquid in suction nozzle is easy to stick on pipettor in actual use, thereby change the new suction nozzle of suction nozzle after stain, cause the cross pollution of sampling next time.Particularly during pipettor horizontal, Liquid Residue refluxes, and more easily pollutes.
Therefore, how realizing a kind of suction nozzle of can good sealing effect and can coordinate with the pipettor gun head of different brands is technical problem urgently to be resolved hurrily in the industry.
Utility model content
The utility model proposes a kind of suction nozzle of Novel belt potted line, solved the problem that suction nozzle sealing effectiveness of the prior art is not good and cannot coordinate with the pipettor gun head of different brands.
The technical solution of the utility model is achieved in that
A kind of suction nozzle of Novel belt potted line, comprise: suction nozzle body, it is lower end that described suction nozzle body is used for one end of imbitition, one end that described suction nozzle body is used for connecting liquid-transfering gun is upper end, described this external surface of suction nozzle upper end is provided with the reinforcement of vertical direction, described this external surface of suction nozzle lower end is provided with for measuring the graduation mark of liquid volume in described suction nozzle body, and described suction nozzle body internal surface upper end is provided with at least one potted line along the circumferential direction.
Further, described potted line quantity is three, and the outside diameter circle of described potted line reduces from top to bottom successively.
Further, the shape of cross section of described potted line is circular, triangle or trapezoidal.
Further, described potted line is that elastomeric material is made.
Further, described reinforcement is at least 3 and distribute along described suction nozzle body axis Central Symmetry.
The beneficial effects of the utility model are: pass through such scheme, the potted line of circumferencial direction is set in suction nozzle body internal surface upper end, thereby make the rifle head of pipettor when coordinating with suction nozzle, because the extruding of potted line has reached hermetic effect, simultaneously can be suitable with the pipettor gun head of different size, thereby there will not be because suction nozzle coordinates obscission tight and that cause with pipettor gun head, and simple in structure, be easy to manufacture.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the planar structure schematic diagram of first embodiment of suction of a kind of Novel belt potted line of the utility model;
Fig. 2 is the sectional structure schematic diagram of the suction nozzle of Novel belt potted line shown in Fig. 1.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
An embodiment referring to the suction nozzle of a kind of Novel belt potted line of the utility model shown in Fig. 1 and Fig. 2, comprising: suction nozzle body, and it is lower end that described suction nozzle body is used for one end of imbitition, one end that described suction nozzle body is used for connecting liquid-transfering gun is upper end.Described this external surface of suction nozzle upper end is provided with the reinforcement 2 of vertical direction, and reinforcement 2 quantity are 6 and along the distribution that is centrosymmetric of described suction nozzle body axis.Reinforcement 2 makes suction nozzle body not be prone to stress deformation, has improved the intensity of suction nozzle body.Described this external surface of suction nozzle lower end is provided with for measuring the graduation mark 3 of liquid volume in described suction nozzle body.Described suction nozzle body internal surface upper end is provided with three potted lines 1 along the circumferential direction, and the outside diameter circle of described potted line 1 reduces from top to bottom successively.Preferably, the shape of cross section of described potted line 1 is circular, and simple in structure and easily manufacture, can be also triangle or trapezoidal, within such structural change still falls into protection domain of the present utility model.
Preferably, described potted line 1 is made for silica gel, and with the bonding connection of suction nozzle body.Silica gel has the advantages that to be difficult for burn into good airproof performance.Potted line 1 also can be directly and this body by integral forming of suction nozzle, thereby without independent manufacture, within such structural change still falls into protection domain of the present utility model.When pipettor gun head stretches into the inner chamber of suction nozzle body, pipettor gun head can come in contact, push with potted line 1, thereby utilize potted line 1 and the frictional force of rifle head to realize fixing, prevent that suction nozzle body from coming off from pipettor gun head, simultaneously can be suitable with the pipettor gun head of different size, without in addition suction nozzle body being changed, easy to use.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
