Abstract
The utility model discloses a novel long-stem funnel for a chemical teaching experiment. The novel long-stem funnel comprises a funnel, a tube body, a ferrule, an insertion tube, a fixing plate and a right-angled guide pipe. The novel long-stem funnel is characterized in that the funnel is fixedly connected with the tube body, the ferrule is arranged below the funnel, fixed on the tube body and connected with the insertion tube; the fixing plate is connected onto the insertion tube; the right-angled guide pipe is connected with the interior of the insertion tube. The novel long-stem funnel is reasonable in design, simple in structure and convenient to use, can effectively decreases the possibility of a gas block-up phenomenon under a certain situation, enables diluted hydrochloric acid to flow into a conical flask smoothly so as to avoid the damage to the long-stem funnel, and guarantees the smooth accomplishment of the experiment.
Description
Technical field
The utility model relates to chemistry teaching technique with the apparatus field, is specifically related to a kind of new chemical education experiment long neck funnel.
Background technology
In the generating means of product in laboratory carbon dioxide, when watery hydrochloric acid being tended to cause when long neck funnel is poured conical flask into gas stifled, cause watery hydrochloric acid not flow into smoothly in conical flask, watery hydrochloric acid is deposited in body, can not discharge by actv., be easy to like this cause certain damage to long neck funnel, to experiment, bring certain puzzlement, cause experiment not complete smoothly.
Utility model content
The purpose of this utility model is to provide a kind of new chemical education experiment long neck funnel, effectively alleviates the generation of the stifled phenomenon of gas under a stable condition, and watery hydrochloric acid is flowed in conical flask smoothly, avoids causing damage to long neck funnel, guarantees that experiment completes smoothly.
To achieve these goals, the technical solution of employing is the utility model:
A kind of new chemical education experiment long neck funnel, comprise: funnel 1, body 2, lasso 3, intubate 4, adapter plate 5, right angle conduit 6, it is characterized in that: funnel 1 is fixedly connected with body 2, funnel 1 has lasso 3, and lasso 3 is fixed on body 2, and lasso 3 is connected with intubate 4, in intubate 4, be connected with adapter plate 5, in intubate 4, be connected with right angle conduit 6, adapter plate 5 can be movable downwards by the movable axis being connected with intubate 4, and the length of right angle conduit 6 is a little more than funnel 1 highest point.
The beneficial effect that the utility model can produce: reasonable in design, simple in structure, easy to use, under a stable condition, effectively alleviate the generation of the stifled phenomenon of gas, watery hydrochloric acid is flowed in conical flask smoothly, avoid causing damage to long neck funnel, guarantee that experiment completes smoothly.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment
In conjunction with Fig. 1, present embodiment is described, a kind of new chemical education experiment long neck funnel, comprise funnel 1, body 2, lasso 3, intubate 4, adapter plate 5, right angle conduit 6, funnel 1 is fixedly connected with body 2, funnel 1 has lasso 3, and lasso 3 is fixed on body 2, and lasso 3 is connected with intubate 4, in intubate 4, be connected with adapter plate 5, in intubate 4, be connected with right angle conduit 6.
In the utility model, adapter plate 5 can be movable downwards by the movable axis being connected with intubate 4, and the length of right angle conduit 6 is a little more than funnel 1 highest point.
During use, first body 2 is put in conical flask, right angle conduit 6 is inserted in intubate 4, by adapter plate 5, held, when testing, watery hydrochloric acid flows in body 2 by funnel 1, while there is the stifled phenomenon of gas, can it slowly be discharged by right angle conduit 6, can under a stable condition, alleviate the generation of the stifled phenomenon of gas, guarantee that experiment completes smoothly.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
