Description
Technical field：
The utility model is related to a kind of physics inertia experimental demonstration device.
Background technology：
In Physics Course teaching, inertia phenomena is the key content of Physics Course, teacher usually need by instrument come
Its physical phenomenon is demonstrated, student is not readily understood to its physical principle, student is difficult to be better understood from principle therein, therefore teacher
In explanation, it is impossible to allow student preferably to observe and understand, cause teaching efficiency to get half the result with twice the effort.
The content of the invention：
The purpose of this utility model is to provide a kind of physics inertia experimental demonstration device.
Above-mentioned purpose is realized by following technical scheme：
A kind of physics inertia experimental demonstration device, its composition includes：Base, catapult-launching gear and supporting plate, described base
Top both sides are respectively arranged with pole and ejection fixed mount, and described ejection fixed mount is connected with described catapult-launching gear, described
Catapult-launching gear there is upper shell and lower house, described upper shell and described lower house is connected through a screw thread, and described is upper
Through hole one is offered at housing and described lower house home position, the cylindricality that is internally provided with of described upper shell pushes away cylinder, institute
The cylindricality stated is pushed away and through hole two is provided with cylinder home position, and pull bar is inserted between described through hole one and described through hole two,
Described pull bar is connected with fastener, and described fastener is connected with push rod.
Described physics inertia experimental demonstration device, described pole upper end tiling has described supporting plate, described
The middle position of supporting plate be provided with path groove, be placed with experiment ball in described path groove.
Described physics inertia experimental demonstration device, described cylindricality pushed away and set at cylinder and described lower house inner side end
There is spring.
Described physics inertia experimental demonstration device, in described fastener is machined with for hollow cylindrical structure and inner side cambered surface
Helicitic texture, described push rod and described pull bar one end is provided with external screw thread.
The beneficial effects of the utility model：
Supporting plate is placed on the upper end of pole in experiment for the utility model, places experiment ball after supporting plate stabilization
In the path groove of supporting plate, prevent experiment ball from rolling, then pull pull bar, it is flat to pull bar direction that pull bar band moving column type pushes away cylinder
Move, push away cylinder and drive spring-compressed, when compressing to a certain extent, hand is left from pull bar, under the elastic force effect of spring, column type
Push rod is translated to push rod direction, the contacts side surfaces of push rod and supporting plate, and supporting plate is released rapidly from the upper end of pole, makes support
Experiment ball on plate is dropped into the groove on pole top, completes inertia experiment.
Brief description of the drawings：
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is the structural representation that cylindricality pushes away cylinder.
