Abstract
The utility model relates to a teaching instrument, in particular to a compressed air fire catcher used for the compressed air ignition experiment and provided with the function of adding the gun cotton. The compressed air fire catcher is provided with a base, a transparent cylinder is arranged on the base, and a piston with a piston rod is arranged in the cylinder. The compressed air fire catcher is characterized in that a conical through hole is arranged at the upper end of the transparent cylinder, so that when the students do experiments, the teacher has no need to screw down the end cover on the fire catcher to add the gun cotton any longer, only pulls the piston rod to the top position by hands, and adds an amount of gun cotton lump through the conical through hole for adding the gun cotton, and then the students can begin to do experiments conveniently, so that the experimental phenomena is not influenced, meanwhile the return resistance of the piston rod can be reduced to speed up the piston rod to return. The compressed air fire catcher has the advantages that the structure is simple, and the fire catcher is not easy to damage and is convenient and flexible to use.
Description
Technical field
The utility model relates to instruments used for education, is that a kind of utilization instrument of igniting is made air compression air compression that having of experiment add the guncotton function instrument of igniting of igniting specifically.
Background technology
We know, the Physical Education Teacher utilizes the instrument of igniting to do the air compression and ignites when testing, the existing instrument of igniting does not add guncotton function or structure at present, when the teacher does air compression and ignites experiment with the instrument of igniting, whenever doing once experiment all needs to screw off the instrument upper end cover of igniting and adds guncotton, very inconvenient and waste time and energy.
Summary of the invention
The utility model proposes a kind of simple in structure, easy to operate air and compresses the instrument of igniting at the deficiencies in the prior art.
A kind of air compression instrument of igniting is provided with base, base is provided with transparent cylinder body, is provided with the piston of band piston rod in the cylinder body, it is characterized in that the upper end of transparent cylinder body is provided with a conical through-hole.
The utility model is when student experimenting, the teacher no longer needs to screw off the instrument upper end cover of igniting and adds guncotton, only move to and push up the position, after an amount of guncotton group of conical through-hole interpolation guncotton circular hole interpolation, can begin easily to do to compress to ignite and test with the handgrip piston rod, so do not influence experimental phenomena, the time can also reduce the resistance of piston rod return, accelerate the piston rod return, have simple in structure, not fragile, advantage such as flexible and convenient to use.
Description of drawings.
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment.
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of air compresses the instrument of igniting, be provided with base 1, base 1 is provided with transparent cylinder body 2, be provided with the piston 4 of band piston rod 3 in the cylinder body 2, the upper end that it is characterized in that transparent cylinder body 2 is provided with a conical through-hole 5, during student experimenting, the teacher no longer needs to screw off the instrument upper end cover of igniting and adds guncotton, only moves the position, top to the handgrip piston rod, after an amount of guncotton group of conical through-hole interpolation guncotton circular hole interpolation, can begin to do compression easily and ignite and tested, thus do not influence experimental phenomena, the time can also reduce the resistance of piston rod return, accelerate the piston rod return, have advantages such as simple in structure, not fragile, flexible and convenient to use.
