Abstract
The invention discloses an anti-bursting test tube, which comprises a test tube body, wherein the test tube body comprises an inner tube and an outer tube; the inner tube is connected into the outer tube in a sleeving manner; the inner tube and the outer tube are cylindrical straight tubes; the top end of the inner tube is provided with an opening sealing plug; the bottom of the inner tube is provided with an inner bottom end; the bottom of the outer tube is provided with an outer bottom end; the inner bottom end and the outer bottom end are both curved; the radians of the inner bottom end and the outer bottom end are both 2.46; the diameter of the outer end surface of the inner tube is 1/1.3 of the diameter of the inner end surface of the outer tube. The anti-bursting test tube has the advantages that disadvantages in the prior art can be overcome by the anti-bursting test tube, and the structural design is reasonable and novel.
Description
Technical field
The present invention relates to a kind of anti-cracking test tube, belong to teaching equipment field.
Background technology
Test tube, the instrument that chemical laboratory is conventional, serve as the reaction vessel of a small amount of reagent, when room temperature or heating, (should preheat before heating, not so test tube easily bursts) uses.Test tube divides common test tube, tool test tube, centrifuge tube etc. multiple.In teaching demonstration is tested, a lot of experiments need to heat, and in heating process, if preheating deficiency, cause test tube to burst sometimes, and when test tube bursts, examination liquid in pipe bursts out and demonstration teacher can be made to scald.
Summary of the invention
The deficiency existed for prior art, the technical problem to be solved is to provide a kind of anti-cracking test tube, easy to use, prevents test tube from bursting, uses safety.
For solving above-mentioned technical problem, the present invention adopts the technical scheme that, a kind of anti-cracking test tube, including test tube body, test tube body includes inner and outer tubes, inner tube is socketed in outer tube, and inner and outer tubes are cylindrical straight tube, and inner tube top is provided with sealing plug, the bottom of inner tube is provided with interior bottom, the bottom of outer tube is provided with outer bottom, interior bottom and outer bottom and is arc, and the radian of interior bottom and outer bottom is 2.46；The 1/1.3 of the inner face diameter of a diameter of outer tube in outer face of said inner tube；Between said inner tube and outer tube, this only has some equally distributed tracheas, and trachea is perpendicular to inner tube outer surface and arranges；Described trachea is cylindrical tube, the internal cavities UNICOM internal tube space of trachea, and the end of trachea passes outer tube wall；2 times of the thickness that thickness is inner pipe wall of described interior bottom, the thickness of outer bottom is 2.3 times of the thickness of outer tube wall.
Optimizing, above-mentioned anti-cracking test tube, the outside of described outer bottom is provided with metal wrap sheet.
It is an advantage of the current invention that it can overcome the drawback of prior art, reasonable in design is novel.The technical scheme of the application uses the mode of inner and outer tubes two-layer body socket to connect, no matter when heating, which layer body bursts, and internal liquid can be kept to burst out, and mode user is injured.Being disposed to of trachea prevents when heating, occurs owing to intraductal atmospheric pressure strengthens the situation making inner tube burst.The thickness of interior bottom and outer bottom is the uniformity in order to increase heating more than pipe thickness, prevents from bursting.Metal wrap sheet utilizes the heat transmitting of metal so that heating process is more uniform, prevents from bursting.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
In figure: 1 be inner tube, 2 be outer tube, 3 be sealing plug, 4 be interior bottom, 5 be outer bottom, 6 be trachea, 7 for metal wrap sheet.
Detailed description of the invention
The technical characterstic of the present invention is expanded on further below in conjunction with the accompanying drawings with specific embodiment.
The present invention is a kind of anti-cracking test tube, including test tube body, test tube body includes inner and outer tubes, inner tube is socketed in outer tube, and inner and outer tubes are cylindrical straight tube, and inner tube top is provided with sealing plug, the bottom of inner tube is provided with interior bottom, the bottom of outer tube is provided with outer bottom, interior bottom and outer bottom and is arc, and the radian of interior bottom and outer bottom is 2.46；The 1/1.3 of the inner face diameter of a diameter of outer tube in outer face of said inner tube；Between said inner tube and outer tube, this only has some equally distributed tracheas, and trachea is perpendicular to inner tube outer surface and arranges；Described trachea is cylindrical tube, the internal cavities UNICOM internal tube space of trachea, and the end of trachea passes outer tube wall；2 times of the thickness that thickness is inner pipe wall of described interior bottom, the thickness of outer bottom is 2.3 times of the thickness of outer tube wall.The outside of described outer bottom is provided with metal wrap sheet.
It is an advantage of the current invention that it can overcome the drawback of prior art, reasonable in design is novel.The technical scheme of the application uses the mode of inner and outer tubes two-layer body socket to connect, no matter when heating, which layer body bursts, and internal liquid can be kept to burst out, and mode user is injured.Being disposed to of trachea prevents when heating, occurs owing to intraductal atmospheric pressure strengthens the situation making inner tube burst.The thickness of interior bottom and outer bottom is the uniformity in order to increase heating more than pipe thickness, prevents from bursting.Metal wrap sheet utilizes the heat transmitting of metal so that heating process is more uniform, prevents from bursting.
Certainly, described above is not limitation of the present invention, and the present invention is also not limited to the example above, those skilled in the art, in the essential scope of the present invention, the change made, retrofits, adds or replaces, all should belong to protection scope of the present invention.
