Compared with prior art, the advantage of the utility model embodiment is: while using this projectile motion test instrument to do level throw motion, signal projector accelerates to slide into the end of slideway from the initiating terminal of slideway, from slideway, dishes out and does projectile motion.Owing to being arranged on signal receiver on column, signal projector in doing the process of projectile motion constantly to signal receiver transmitted signal, signal receiver is according to the movement position of this signal tracer signal transmitter, because this signal projector is only subject to the impact of weight in doing the process of projectile motion, there is no the impact of paper tape friction force, this projectile motion test instrument precision is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the projectile motion test instrument of the utility model embodiment.
Embodiment
Below by specific embodiment, also by reference to the accompanying drawings the utility model is described in further detail.
Be illustrated in figure 1 a kind of projectile motion test instrument that the present embodiment provides, comprise column 102, slideway 106, signal projector 107 and signal receiver 105; Slideway 106 is fixedly installed on column 102 and signal projector 107 coordinates with slideway 106; Be signal projector 107 does projectile motion from the initiating terminal of slideway 106 accelerates to slide into the end of slideway 106; Signal receiver 105 is arranged on the top of column 102 for receiving the signal of signal projector 107 transmittings.
While using this projectile motion test instrument to do level throw motion, signal projector 107 accelerates to slide into the end of slideway 106 from the initiating terminal of slideway 106, from slideway 106, dishes out and does projectile motion.Owing to being provided with signal receiver 105 on column 102, signal projector 107 in doing the process of projectile motion constantly to signal receiver 105 transmitted signals, signal receiver 105 is according to the movement position of this signal tracer signal transmitter 107, because this signal projector 107 is only subject to the impact of weight in doing the process of projectile motion, there is no the impact of paper tape friction force, this projectile motion test instrument precision is high.
Wherein, signal projector 107 comprises the roller ball of round pie; In slideway 106, be provided with chute; Roller ball and chute are slidably matched.By the coordinating of roller ball and chute, signal projector 107 accelerates to slide into the end of slideway 106 from the initiating terminal of slideway 106, thereby avoids signal projector 107 from the interior disengaging of slideway 106, reduces the mortality of this projectile motion test instrument.Preferably, the width of chute is greater than the thickness of roller ball, and roller ball is embedded in chute, guarantees that roller ball can not depart from slideway when down sliding.
In addition, signal projector 107 also comprises the transmitting terminal 108 of a side that is arranged on roller ball; Transmitting terminal 108 is annular.Due to signal projector 107 in doing the process of projectile motion all the time in rotation status, the signal sending for the signal projector 107 making in rotation status cannot be received by signal receiver 105, this signal projector 107 also comprises annular transmitting terminal 108, be that signal projector 107 is in the process of rotation, the transmitting terminal 108 of annular transmits to 360 ° of directions all the time, and the signal sending while avoiding transmitting terminal 108 divergence signal receiver 105 cannot be received by signal receiver 105.
Further, because signal projector 107 can move certain displacement at vertical direction and horizontal direction in the process of projectile motion, in order to ensure signal receiver 105, receive the signal that signal projector 107 sends, signal receiver 105 is fan-shaped; Signal receiver 105 comprises the receiving end 112 that is arranged on a fan-shaped right-angle side; Receiving end 112 is done the direction of projectile motion towards signal projector 107.The receiving end 112 that is signal receiver 105 is positioned at a fan-shaped right-angle side, and this receiving end 112 is done the direction of projectile motion towards signal projector 107.Preferably, the angle of inclination of this receiving end 112 is 45 °, can also be 50 ° or other angle arbitrarily certainly.Before this signal receiver 105 is fastening with column 102, can regulates its position on column 102, thereby regulate the height of this signal receiver 105, the angle of inclination of receiving end 112 also can regulate arbitrarily certainly.
Further, this projectile motion test instrument also comprises zeroing baffle plate 104; Zeroing baffle plate 104 is arranged on the end of slideway 106.When doing projectile motion, need position when accurately this signal projector 107 is dished out from slideway 106, by this zeroing baffle plate 104, can determine position when this signal projector 107 is dished out from slideway 106, thereby make projectile motion test more accurate.
Because this signal projector 107 starts to accelerate to slide from the initiating terminal of slideway 106, this projectile motion test instrument also comprises stationary installation 109; Stationary installation 109 is arranged on the initiating terminal of slideway 106, for signal projector 107 is fixed on to slideway 106.This signal projector 107, before down sliding, is fixed on this signal projector 107 on slideway 106 by this stationary installation 109.While starting to test, stationary installation 109 and signal projector 107 are departed from, signal projector 107 can accelerate downwards to slide along slideway 106.
For fear of this signal projector 107, in sliding process, can cause rocking of slideway 106, in order to make slideway 106 firm, this projectile motion test instrument also comprises support bar 111; One end of support bar 111 is fixedly connected with column 102, and the other end is fixedly connected with slideway 106.Wherein, one end of this support bar 111 is fastened on column 102 after can sliding into certain position on column 102; and the other end of this support bar 111 also can slide and fastening on slideway 106, regulate the position of this support bar 111, thereby guarantee to slide firm.
Further, the middle part of support bar 111 is provided with for regulating the set screw 110 of the length of support bar.By this set screw 110, can regulate the length of support bar 111.Particularly, this support bar 111 is comprised of two poles, and wherein one end of a pole and slideway 106 are fixing, and the other end is provided with waist-shaped hole, and one end of another pole and column are fixed, and the other end is provided with through hole.This set screw 110 is passed after this through hole and waist-shaped hole, and set screw 110 can be slided and be fastening in waist-shaped hole, and then regulates the length of support bar 111.
Use this projectile motion test instrument when testing, can carry out level throw motion test, can carry out oblique upper paraboloiding movement test, certainly can also carry out the tiltedly lower exercise test of throwing, the angle of impelling while doing different parabolic experiment in order to show, this projectile motion test instrument also comprises index dial 103; Index dial 103 is fixedly installed on the end of slideway 106.Be the angular adjustment of slideway 106, this index dial 103 is also along with rotation, and on column 102, is provided with indicateing arm, thereby reads the scale on the index dial 103 of this indicateing arm indication.
Further, this projectile motion test instrument also comprises base 101; Column 102 is vertically fixed on base 101.These base 101 columns 102 play support, firm effect, avoid column 102 when carrying out projectile motion test to rock.
