Physical equation can be in the hope of theoretical level distance that demonstration bead is cast;Basilisk is finally operated again carries out flat throw, tiltedly
Demonstration is thrown, the real standard distance that obtained demonstration bead is cast is compared with theoretical level distance, that is, can verify that flat
It throws, tiltedly throw theory.
It further, further include rotary indicator 6 and dial 7 corresponding with rotary indicator 6, rotation in above-described embodiment
Pointer 6 is connect with bar 1 is thrown, and the corresponding corner for throwing bar 1 of the corner of rotary indicator 6 can easily be read from dial 7 in this way
Verify data is avoided being carried out cumbersome measurement using measuring tool, improves the efficiency of verifying.
Further, the hole for installing gag lever post is provided in above-described embodiment in support side plate 3, in this way limit bar
5 can be inserted into corresponding mounting hole in support side plate 3, easily limit bar 5 to be installed in support side plate, to realize
To the position-limiting action for throwing bar 1.
Further, in above-described embodiment installation limit bar 5 hole have it is multiple, each hole independently from throw bar 1 it is different
Rotation angle it is corresponding, limit bar 5 can neatly be installed in this way according to verifying angle difference, to realize flat throw or difference
The demonstration and verification that angle is tiltedly thrown.
Further, for install the corresponding throwing bar 1 in the hole with respect to the horizontal plane inverse time for limiting bar 5 in above-described embodiment
The rotation angle in needle direction is 30 °, 45 °, 60 °, 75 ° and 90 °, because it is teaching that 30 °, 45 °, 60 °, 75 ° and 90 ° corresponding
In common numerical value, therefore can be convenient teacher student and carry out calculating verifying.
Further, support side plate 3 is equipped at least one and corresponds to the use for throwing bar initial angle in above-described embodiment
In the hole for installing the limit bar 5, limit bar 5 is inserted into above-mentioned hole, then throw bar 1 rise throw initial angle will be by
The limit bar 5 being inserted into above-mentioned hole is fixed, therefore when repeating to test, and can be unified initial rise and be thrown position, avoid because
Initial rise of positioning throws angle difference and generates different test datas.
Further, the hole of installation limit bar 5 is one of round, rectangle or triangle in above-described embodiment.
Fig. 2 gives the flat basilisk teaching aid thrown and tiltedly thrown of another verifying, further includes ranging bucket 8, on ranging bucket
It is provided with ranging scaled flexible ruler 9;When flat throwing, tiltedly throwing demonstration and verification, calculating can be first passed through it can be concluded that demonstration bead
Estimated position distance, then ranging bucket 8 will be placed in corresponding demonstration with small according to the estimated position distance of demonstration bead
Then ball estimated position position operates basilisk and carries out flat throwing, tiltedly throws demonstration, if demonstration accurately falls in ranging bucket with bead
It is interior, so that it may intuitively to obtain the conclusion being proved to be successful.Scaled flexible ruler 9 can be also set on ranging bucket 8, utilize scaled flexible ruler 9
Ranging bucket 8 can easily be measured and arrive the distance of basilisk, so need not additionally prepare distance measurement tools again, so as to
More easily carry out the above-mentioned flat operation thrown, tiltedly throw demonstration and verification.
Further, it in above-mentioned all embodiments, throws bar shaft 2 and is removably disposed in support side plate 3, throwing bar 1 can
It is releasably connected to and throws in bar shaft 2, support side plate 3 is removably disposed on support baseboard 4, and rotary indicator 6 is removably
It is connect with bar 1 is thrown, ranging bucket 8 is removably spliced to form mutually by plate part, and scaled flexible ruler 9 is removably arranged described
On ranging bucket 8.By be by design of major parts it is dismountable, to realize the flattening of product packaging, such product is large quantities of
When amount storage transport, the space of storage transport can be saved;Teaching aid is to can be assembled, removably simultaneously, moreover it is possible to which exercise student ' is moved
Hand ability.
