Abstract
The utility model embodiment disclose it is a kind of flat throw recorder, including magnetic drawing, the flat throwing guide rail, the air level being arranged at the top of the magnetic drawing and the first magnetic ball for flat parabolic experimental with terminal horizontal outlet that are arranged on the magnetic drawing one on corner.Using the utility model, the equipment based on magnetic drawing and magnetic ball, directly the track of level throw motion is recorded, it is more convenient efficiently to have studied level throw motion, it can be widely used in study education, demonstration, and student experimenting.
Description
Technical field
It the utility model is related to a kind of teaching experiment utensil, more particularly to a kind of flat throwing recorder.
Background technology
Object is dished out in the horizontal direction with certain initial velocity, if object is only called by Action of Gravity Field, such motion
Level throw motion.Level throw motion can regard the conjunction fortune of the movement of falling object of the linear uniform motion and vertical direction of horizontal direction as
It is dynamic.The object of level throw motion, because suffered bonding force is constant force, so level throw motion is uniformly changed velocity motion, flat parabolic
The movement locus of body is a parabola.
Commonly used main two methods, it is stroboscopic method and and trace-point method respectively during flat parabolic experimental.But this two
There is also drawback for kind method.Stroboscopic method is first to allow object to do level throw motion and recorded with high speed camera, then passes through electricity
Brain parses level throw motion, but this method is complicated, and use cost is high；Trace-point method is to allow object to do multiple initial velocity phase
With level throw motion, object is determined in information such as positions sometime, to study the track of flat throwing and rule, but using multiple
Experiment, the discontinuous of experiment is caused, if being connected to obtain the bad result that can increase error, experiment can be influenceed, it is impossible to reach expected
Effect.Existing experimental apparatus can not parse level throw motion more vividly, increase teaching difficulty.
The content of the invention
The utility model embodiment technical problem to be solved is, there is provided one kind is flat to throw recorder.It can be formed directly in
Level throw motion track record, be easy to flat throw teaching.
In order to solve the above-mentioned technical problem, the utility model embodiment provides a kind of flat throwing recorder, including magnetic drawing
Plate, there is the flat throwing guide rail of terminal horizontal outlet, be arranged at the magnetic drawing on corner is arranged on the magnetic drawing one
Air level at the top of plate and the first magnetic ball for flat parabolic experimental.
Further, the magnetic drawing is in the flat photocell eye thrown guide rail lower section and be provided with perpendicular separation.
Further, the magnetic drawing surface has grid square.
Further, tongue tube, another corner of magnetic drawing are provided with the flat Horizontal Exit for throwing guide rail
On be vertically installed with electrical solenoid, be used to place the second magnetic ball, the electrical solenoid lower port and the level in electrical solenoid
Outlet is in same horizontal line.
Further, the magnetic drawing top is additionally provided with time counting display screen.
Further, the magnetic drawing bottom is provided with the receiver for accepting the first, second magnetic ball.
Further, the magnetic drawing is vertically fixedly installed on substrate, and the substrate is provided with Level tune spiral shell
Nail.
Implement the utility model embodiment, have the advantages that：The utility model using magnetic drawing and magnetic ball as
Basic equipment, directly the track of level throw motion is recorded, it is more convenient efficiently to have studied level throw motion, it can be widely used in
Study education, demonstration, and student experimenting.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Type is described in further detail.
Structural representation shown in reference picture 1.
One kind of the utility model embodiment is flat to throw recorder, including magnetic drawing 1, sets on magnetic drawing 1 one on corner
The air level 3 that there is the flat throwing guide rail 2 of terminal horizontal outlet, be arranged at the top of magnetic drawing 1 and for flat parabolic experimental
First magnetic ball 4.
Magnetic drawing 1 is passed through in the flat photocell eye 5 thrown guide rail lower section and be provided with perpendicular separation for detection magnetic ball
Signal.
The surface of magnetic drawing 1 has grid square, the track that magnetic ball is formed is easy to measuring coordinate.
Tongue tube 6 is provided with the flat Horizontal Exit for throwing guide rail 2, magnetic drawing is vertically installed with electric spiral shell on 1 another corner
Spool 7, electrical solenoid 7 is interior to be used to place the second magnetic ball 8, and electrical solenoid lower port is in same horizontal line with the Horizontal Exit
On.
When the first magnetic ball 4 is dished out from flat throwing guide rail 2, tongue tube 6 is triggered, the dead electricity of electrical solenoid 7 is made by reverser, made
8 synchronous freely falling body of the second magnetic ball in electrical solenoid 7.
The top of magnetic drawing 1 is additionally provided with time counting display screen 9, the time triggered for showing photocell eye 5.
The bottom of magnetic drawing 1 is provided with the receiver 10 for accepting first, second magnetic ball.
Magnetic drawing 1 is vertically fixedly installed on substrate 11, and substrate is provided with horizontal adjustment screw 12, makes magnetic drawing 1
Adjust in the posture needed for experiment.
The utility model is tested by following steps：
1) preparation before testing：
1st, flat throwing guide rail is fixed on demonstration board upper left side with Universal clamp.
2nd, flat throwing guide rail is checked, it is desirable to which guide rail latter end horizontal component is vertical with weight line.
3rd, by the adjustment of four leveling bolts of bottom plate, make air level placed in the middle, both flat board and horizontal plane.
2）Experimentation
1st, magnetic ball is put into by the flat conduit mouth for throwing guide rail, bead is slided along conduit, and fortune work(track, note are drawn in plate face
Record data.
2nd, bead starting point, test of many times, record data are changed.
3rd, whole and data, analysis is calculated.
More optimizedly, by the second magnetic ball of synchronous electrical solenoid 7, the second magnetic ball and the first magnetic ball are made in level throw motion
Do the movement of falling object simultaneously.
For certain above-described embodiment only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with this
The people of technology can understand content of the present utility model and implement according to this, and protection model of the present utility model can not be limited with this
Enclose.The modification that all Spirit Essences according to the utility model main technical schemes are done, it should all cover in guarantor of the present utility model
Within the scope of shield.
