Abstract
The utility model relates to a kind of glue head dropper, comprise Capsule and glass dropper, described Capsule is arranged on the upper end of glass dropper, the junction of described Capsule and glass dropper is provided with thread bush, the lower end inner wall of described thread bush is screwed together by screw thread and glass dropper, and the upper end inwall of thread bush is close on the outer surface of Capsule, and the inwall of thread bush offers groove, be provided with sealing ring in described groove, the body of described glass dropper is provided with graduation mark from top to bottom.The utility model structure is simple, reasonable in design, by being provided with thread bush in the junction of Capsule and glass dropper, and being provided with sealing ring, improving its sealing effectiveness, prevents the junction of Capsule and glass dropper from leaking gas.
Description
Technical field
The utility model relates to chemical apparatuses apparatus field, particularly relates to a kind of glue head dropper.
Background technology
Glue head dropper is also known as Capsule dropper, and it is a kind of instrument for drawing or drip a small amount of liquid reagent, and glue head dropper is made up of Capsule and glass dropper, has straight shape, directly shape to have buffering ball and bending to have several forms such as buffering ball.
Current glue head dropper in use, usually because Capsule and glass drop pipe junction are not tight, easily causes gas leakage, change in time.This just causes the increase of use cost, and What is more can because the poorly sealed close inefficacy causing liquid reagent of Capsule.
Utility model content
The utility model, in order to overcome deficiency of the prior art, provides a kind of glue head dropper, improves its sealing property.
The utility model is achieved through the following technical solutions:
A kind of glue head dropper, comprise Capsule and glass dropper, described Capsule is arranged on the upper end of glass dropper, the junction of described Capsule and glass dropper is provided with thread bush, the lower end inner wall of described thread bush is screwed together by screw thread and glass dropper, the upper end inwall of thread bush is close on the outer surface of Capsule, and the inwall of thread bush offers groove, is provided with sealing ring in described groove.
As optimal technical scheme of the present utility model, described sealing ring is " O " RunddichtringO.
As optimal technical scheme of the present utility model, the body of described glass dropper is provided with graduation mark from top to bottom, can draw or drip the amount of required reagent more accurately, brings larger guarantee to the accuracy of experiment.
As optimal technical scheme of the present utility model, the lower end of described glass dropper is provided with label.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, by being provided with thread bush in the junction of Capsule and glass dropper, and are provided with sealing ring, improve its sealing effectiveness, prevent the junction of Capsule and glass dropper from leaking gas.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-Capsule; 2-glass dropper; 3-thread bush; 4-groove; 5-sealing ring; 6-graduation mark; 8-label.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of glue head dropper, comprise Capsule 1 and glass dropper 2, described Capsule 1 is arranged on the upper end of glass dropper 2, the junction of described Capsule 1 and glass dropper 2 is provided with thread bush 3, the lower end inner wall of described thread bush 3 is screwed together by screw thread and glass dropper 2, the upper end inwall of thread bush 3 is close on the outer surface of Capsule 1, and the inwall of thread bush 3 offers groove 4, is provided with sealing ring 5 in described groove 4.By being provided with thread bush 3 in the junction of Capsule 1 and glass dropper 2, and being provided with sealing ring, improving its sealing effectiveness, prevent the junction of Capsule 1 and glass dropper 2 from leaking gas.
Described sealing ring 5 is " O " RunddichtringO, adopts elastomeric material to make; The body of described glass dropper 2 is provided with graduation mark 6 from top to bottom, can draw or drip the amount of required reagent more accurately, brings larger guarantee to the accuracy of experiment.
The lower end of described glass dropper 2 is provided with label 8, and label 8, in ellipticity, because each glue head dropper has different labels, can not be obscured during use.In addition, because glue head dropper often will be rinsed, by the soda acid in laboratory or other chemicals attack, be rubbed by desktop, label, if write up, easily comes off or is erased, and label is in elliptoid in this programme, label can be avoided to come off or erased.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
