Abstract
The utility model discloses an experimental flat parabolic motion hodoscope. A vertical plate is fixed at one side of a bracket; a ball receiver groove is fixed at the bottom of the bracket and is disposed at the front lower part of the vertical plate; an ejector cylinder is horizontally fixed at the upper end of the bracket; the front part of the ejector cylinder is transversely split to be semi-cylinders; sponge layers soaked with ink are laid on the inner walls of the semi-cylinders; a long rod is fixed on the rear end wall of the rear part of the ejector cylinder; a spring is hitched on the long rod and is buckled between a strike plate and the end wall; projecting plates are arranged at the top of the round strike plate and the top end and a forward strike block is arranged at the center of the round strike plate; long slots are respectively arranged at the corresponding places of the top wall and the bottom wall of the rear part of the ejector cylinder; the projecting plates on the strike plate stretch out from the long slots; and when the projecting blocks are located at the front ends of the long slots, the strike block is located at the rear of the front part of the ejector cylinder. The experimental flat parabolic motion hodoscope is simple, convenient and practical and is convenient to operate and precise and quick to draw the trace.
Description
Technical field
The utility model relates to a kind of experimental provision of describing flat paraboloid track.
Background technology
Student experimenting in the high school physics textbook " is studied the motion of flat paraboloid ", it is the position of determining the bead level throw motion with a hard paper that has an aperture, the experiment that the needs repetition is tens times just can obtain the several position of bead level throw motion process, just can depict the track of bead motion, therefore to spend long time, some student is difficult in and finishes laboratory report on the classroom, and the error of experiment is big.
Summary of the invention
For solving the problem of above existence, the utility model provides a kind of flat throwing trace experiment instrument, and its technical scheme of taking is:
This experiment instrument comprises support and is separately fixed at riser on the support, ball receiving groove and emission cylinder, riser is fixed on the centre position of support one side, ball receiving groove is fixed on the bottom of support and is positioned at the front lower place of riser, the notch direction that ball receiving groove is offered is parallel with the plate face direction of riser, the emission cylinder is horizontally fixed on the upper end of support and the top of close riser, the emission port of emission cylinder and the notch of ball receiving groove are positioned on the same vertical plane, and emission cylinder inner wall side tangent line and riser front side vertical plane are positioned on the same vertical plane, emission cylinder forward part lateral dissection is the semicircle cartridge type, lay the spongy layer that contains ink on the semicircle inwall of this part, be fixed with the stock that is positioned at its inside center position on the rear side end wall of emission cylinder rear section, be with spring on the stock, and stock passes the center that the circle that is located in the emission cylinder is hit plate, Spring Card is connected on hits between plate and the end wall, circle is hit the plate top and the top is provided with tab, its center is provided with the piece that hits forward, the elongated slot that the roof of emission cylinder rear section and diapire offer the position correspondence respectively, the tab that hits on the plate leans out from elongated slot, when projection is positioned at the front end of elongated slot, hit the rear portion that piece is positioned at emission cylinder forward part.
Flexible by spring makes and hits plate trace ball is launched away, stay parabolical vestige on the plate face of riser, so the utility model is simple and practical, and easy to operate, trace is accurately quick.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in the figure, riser 2 is fixed on the centre position in support 1 left side, and ball receiving groove 3 is fixed on the bottom of support and is positioned at the front lower place of riser 2, and the notch direction that ball receiving groove 3 is offered is parallel with the plate face direction of riser 2, and trace ball can be fallen in the ball receiving groove 3.Emission cylinder 4 is horizontally fixed on the upper end of support and the top of close riser 2, the emission port of emission cylinder 4 and the notch of ball receiving groove 3 are positioned on the same vertical plane, and emission cylinder 4 inwall side tangent lines and riser 2 front side vertical planes are positioned on the same vertical plane, make rolling on riser of trace ball.Emission cylinder 4 forward part lateral dissection are the semicircle cartridge type, lay the spongy layer 5 that contains ink on the semicircle inwall of this part, the lint ball that trace ball can blot for the surface, be fixed with the stock 6 that is positioned at its inside center position on the rear side end wall 10 of emission cylinder 4 rear sections, be with spring 7 on the stock 6, and stock 6 passes the center that the circle that is located in the emission cylinder 4 is hit plate 9, spring 7 is connected to hits between plate 9 and the end wall 10, circle is hit plate 9 tops and the top is provided with tab 11, its center be provided with forward hit piece 12, the elongated slot 8 that the roof of emission cylinder 4 rear sections and diapire offer the position correspondence respectively, the tab 11 that hits on the plate 9 leans out from elongated slot 8, when projection is positioned at the front end of elongated slot, hit the rear portion that piece 12 is positioned at emission cylinder 4 forward part.
When carrying out the trace experiment, at first on the front side board face of riser 2, fix a blank sheet of paper with drawing pin, then trace ball is placed on the rear end of emission cylinder 4 forward part, with pulling moving tab 11, it is moved backward along elongated slot 8, the ejection speed of the distance decision trace ball that moves, this moment, spring 7 was gradually reduced.After unclamping tab 11, the spring bullet is stretched, promotion is hit plate 9 and is advanced, hit plate 9 and halt when tab 11 moves to the front end of elongated slot, hit piece 12 and just impact trace ball this moment, makes it roll across spongy layer 5 backs and launch away in emission cylinder 4, and do level throw motion along blank sheet of paper, the inkblot that its movement locus stays on blank sheet of paper when rolling goes on record, and last trace ball drops in the ball receiving groove 3, just finishes the trace experiment of flat paraboloid this moment.
