Abstract
The utility model relates to a chemistry experiment drainage tube belongs to chemistry teaching articles for use technical field. Including being equipped with the outer tube of scale, the outer tube is equipped with the opening for hollow structure and both ends, and the outer tube interpolation is equipped with the inner tube, and the both ends of inner tube all are located the outer tube outside, and the one end of inner tube is installed the liquid medicine and is held nanotube, and it is mutually perpendicular with the inner tube that the liquid medicine holds nanotube, and cross section that the liquid medicine holds nanotube is squarely and length direction one end is equipped with the opening, and diagonal bracing plate is installed to the length direction other end that the liquid medicine holds nanotube, and the liquid medicine holds on nanotube's the lower surface even having laid and is semicircular and rolls protruding, it is flat -plate -shaped that diagonal bracing plate is the rectangle, is the contained angle that diagonal bracing plate and liquid medicine hold between the nanotube 100 120 the head tube wall mounting of outer tube has the piece of controlling that is the L type. The utility model has the advantages of reasonable design, convenient to use, the drainage is effectual, has the liquid medicine interpolation, accelerates the liquid medicine to mix, roll the experiment medicine and measure the liquid level effect.
Description
Technical field
This utility model relates to a kind of chemical experiment drainage tube, belongs to chemistry teaching articles for use technical field of structures.
Background technology
At present, Chemistry Courses often to carry out some chemical experiments, in order to student grasps content further, drainage tube is experimental provision conventional during chemical experiment, and the design of existing drainage tube structure is single, uses and there is inconvenience.
Summary of the invention
The purpose of this utility model is to solve the weak point that prior art exists, a kind of reasonable in design is provided, easy to use, drainage effect is good, has medicinal liquid and adds, accelerates medicinal liquid mixing, roll experimental drug and measure the chemical experiment drainage tube of liquid level effect.
This utility model is achieved through the following technical solutions:
A kind of chemical experiment drainage tube, it is characterized in that and includes setting graduated trocar sheath 1, trocar sheath 1 is provided with opening for hollow structure and two ends, inner tube 2 it is inserted with in trocar sheath 1, it is outside that the two ends of inner tube 2 are respectively positioned on trocar sheath 1, one end of inner tube 2 is provided with medicinal liquid and accommodates pipe 3, it is perpendicular with inner tube 2 that medicinal liquid accommodates pipe 3, the cross section of medicinal liquid receiving pipe 3 is square and length direction one end is provided with opening 4, medicinal liquid accommodates the length direction other end of pipe 3 and is provided with bearing diagonal plate 5, and what the lower surface of medicinal liquid receiving pipe 3 was laid with semicircular in shape uniformly rolls convex grain 7；
The angle that the described rectangular tabular of bearing diagonal plate 5, bearing diagonal plate 5 and medicinal liquid accommodate between pipe 3 is 100 °-120 °；
L-shaped grips 6 is installed on the top tube wall of described trocar sheath 1.
A kind of chemical experiment drainage tube of the present utility model, smart structural design, during use, inner tube is inserted in trocar sheath, then accommodate in pipe by needing the medicinal liquid added to drop to medicinal liquid, medicinal liquid is accommodated pipe as in beaker, stir while making medicinal liquid accommodate the medicinal liquid in pipe and separating out, and medicinal liquid receiving pipe is T-shaped with inner tube, medicinal liquid mixing can be accelerated, the medicinal liquid height in beaker can be measured by the scale on trocar sheath outer wall, additionally, when using as drainage tube, bearing diagonal plate can be resisted against on the inwall of beaker, the steadiness of drain can be improved.In sum, this utility model reasonable in design, easy to use, in chemistry teaching field, there is good application prospect.
Accompanying drawing explanation
The structural representation of Fig. 1: this utility model a kind of chemical experiment drainage tube;
Fig. 2: this utility model medicinal liquid accommodates the structural representation of the lower surface of pipe.
Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
A kind of chemical experiment drainage tube of the present embodiment, including setting graduated trocar sheath 1, trocar sheath 1 is provided with opening for hollow structure and two ends, inner tube 2 it is inserted with in trocar sheath 1, it is outside that the two ends of inner tube 2 are respectively positioned on trocar sheath 1, one end of inner tube 2 is provided with medicinal liquid and accommodates pipe 3, it is perpendicular with inner tube 2 that medicinal liquid accommodates pipe 3, the cross section of medicinal liquid receiving pipe 3 is square and length direction one end is provided with opening 4, medicinal liquid accommodates the length direction other end of pipe 3 and is provided with bearing diagonal plate 5, and what the lower surface of medicinal liquid receiving pipe 3 was laid with semicircular in shape uniformly rolls convex grain 7；The angle that the rectangular tabular of bearing diagonal plate 5, bearing diagonal plate 5 and medicinal liquid accommodate between pipe 3 is 100 °-120 °；L-shaped grips 6 is installed on the top tube wall of trocar sheath 1.
During use, inner tube 2 is inserted in trocar sheath 1, then accommodate needing the medicinal liquid added to drop to medicinal liquid in pipe 3, medicinal liquid is accommodated pipe 3 as in beaker, stir while making medicinal liquid accommodate the medicinal liquid in pipe 3 and separating out, and medicinal liquid receiving pipe 3 is T-shaped with inner tube 2, medicinal liquid mixing can be accelerated, the medicinal liquid height in beaker can be measured by the scale on trocar sheath 1 outer wall, additionally, when using as drainage tube, bearing diagonal plate 5 can be resisted against on the inwall of beaker, the steadiness of drain can be improved.
Upper described only preferred embodiment of the present utility model, not in order to limit this utility model, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
