Technical field：
The utility model is related to teaching aid technical field, and in particular to a kind of physics teaching apparatus for demonstrating.
Background technology：
, it is necessary to use many theorems, axiom etc. in physics teaching, simple explanation is very uninteresting, is unfavorable for student's
Learning and memory, and much formula is easily obscured, and makes the learning interest of student not high, have impact on the progress of teaching.
In order to make teaching more obvious and lively, multiple experiments are provided with physics teaching, it is necessary to use different realities
Apparatus is tested, laboratory apparatus is excessive, cause simply just to coordinate experiment to be imparted knowledge to students when teaching this theorem in teaching, when multiple fixed
Ought to the used time, be stiff explanation when causing explanation, it is impossible to coordinate experiment to be imparted knowledge to students, reduce because laboratory apparatus is excessive
The efficiency of teaching.
Utility model content：
Technical problem to be solved in the utility model is to overcome existing technological deficiency to use there is provided a kind of physics teaching
Apparatus for demonstrating.

Inclined accelerator card, accelerator card lower end connection expansion bracket.
One end away from slide plate in road is accelerated to be provided with acceleration spring on the accelerator card.
Described acceleration spring one end is fixedly connected with accelerator card, the acceleration road that acceleration spring free end is put on accelerator card
It is interior, pull bar is provided with acceleration spring, pull bar is fixedly connected with acceleration spring free end.When accelerator card is laid flat, it can pull
Acceleration spring accelerates to the bead of experiment, to obtain faster speed to the bead of experiment.
The back end of tie rod is connected with handle.
The support is arranged in the stopper slot on pedestal.Frame bottom connects cast iron seat, and cast iron seat keeps the steady of support
It is qualitative, and be arranged in stopper slot can further held stationary for cast iron seat.
The expansion bracket includes hollow pipe and the support bar injected in hollow pipe, support bar and accelerator card hinge connection, branch
Strut is fixed with hollow pipe by the bolt passed from side wall of hollow pipe.
The beneficial effects of the utility model are：Accelerator card and slide plate can be tilted, bead is placed on accelerator card and added
Skidded off after speed from the slide plate other end with demonstrating level throw motion, and accelerator card inclination different height can make bead acquisition different
Speed, and two slide plates can be ejected into the bullet block on long slab to both sides pulling, coarse slideway of the bead on bullet block is slided
It is dynamic to be tested with demonstration friction.
