Abstract
The utility model discloses a tube-plug integrated chemical test tube cap, comprising a whole composed of a cover body 1, an inserted tube 2, and a collateral tube 3. The inserted tube 2 whose center part is provided with the knee of the fold knob 4 is arranged on the top part of the cover body 1. The collateral tube 3 whose opening end is provided with a gum cap 5 is arranged at the bottom side of the top part of the cover body 1. The utility model has the advantages of convenient usage, timesaving and laborsaving operation, safe experiments, obvious effects in improving the teaching experiments, and widespread availability in demonstrators for chemical experiments.
Description
Technical field
The utility model relates to the composite set of a kind of test tube plug and intubate, and particularly a kind of pipe close integrated chemical cap test tube is applicable to chemical experiment teaching aid.
Background technology
In chemical experiment teaching, when doing derivation or importing gas experiment with test tube usually, need be at the single hole or the diplopore plug of test tube mouth mounting strap conduit, the shortcoming of the single hole of this carrying pipe or the configuration of diplopore plug is: need punching earlier on stopper, connect in the conduit one end insertion stopper with bending, have time-consuming, effort, cost is high and unsafe problem, in addition, finish for the test tube heating that fills solid medicine, when taking off test tube, often the aqueous reflux because of in vitro condensing causes that test tube bursts.
Summary of the invention
The purpose of this utility model is to provide a kind of and do derives or when importing gas experiment with test tube, test tube plug and conduit do not need configuration, simultaneously, when giving the test tube heating that fills solid medicine, can test tube be burst, integrate stopper and conduit and easily operation, pipe close integrated chemical cap test tube safe in utilization.
For reaching above purpose, the technical scheme that the utility model adopted is: this pipe close integrated chemical cap test tube, comprise that cover body, intubate, side branch constitute, cover body, intubate, side branch constitute an integral body, and intubate is located at the top of cover body, and side branch is located at the bottom side at the top of cover body, establish the crooked joint of fold at the intubate middle part, flexible one-tenth different angles, and scalable, establish Capsule at side branch mouth end.The utility model is also implemented by following measure: described intubate can be established the 1-2 root, wherein an intubate is stretched out from the top of cover body, the end of another root intubate in inserting cover body is provided with and inserts the connection-peg of invisible spectro adapter, when experiment, if multipath gas is arranged derives, intubate can be established two, and wherein one is stretched into the test tube bottom with taking over to be connected with connection-peg, so that the gas bottom the derivation test tube; Described cover body and intubate and side branch can be injected into an integral body with elastomeric material.When using the utility model; cover body is enclosed within on the test tube mouth; when test tube is heated; the gas that invisible spectro medicine decomposes goes out can directly be derived from intubate; invisible spectro condensate water; the Capsule of side branch can be pulled up, condensate water is flowed out, thereby the protection test tube can not burst because of aqueous reflux is arranged.
Advantage of the present utility model is: easy to use, time saving and energy saving, the experiment safety of operation, can improve the education experiment effect.
Description of drawings
Fig. 1 establishes the embodiment cross-sectional schematic of an intubate for the utility model.
Fig. 2 establishes the embodiment cross-sectional schematic of two intubate for the utility model.
The specific embodiment
Make the utility model with reference to accompanying drawing 1,2.This pipe close integrated chemical cap test tube, comprise that cover body 1, intubate 2, side branch 3 constitute, cover body 1, intubate 2, side branch 3 constitute an integral body, intubate 2 is located at the top of cover body 1, side branch 3 is located at the bottom side at cover body 1 top, establish the crooked joint 4 of fold at intubate 2 middle parts, establish Capsule 5 at 3 mouthfuls of ends of side branch.Described intubate 2 can be established the 1-2 root, and wherein an intubate 2 is stretched out from the top of cover body 1, and an end of another root intubate 2 ' in inserting cover body 1 is provided with and inserts the connection-peg 6 of invisible spectro adapter; Described cover body 1 and intubate 2,2 ' reach side branch 3 can be injected into an integral body with elastomeric material.
