Embodiment
As a kind of embodiment of the present utility model, as shown in Figure 1, 2, 3, a kind of water clock demonstration device, including by bottle
5th, lead to be provided between the water clock time set that dropper 6, air inlet pipe 61 are constituted, the bottle 5 and lead dropper 6, it is described to lead on dropper 6
It is provided with air inlet pipe 61, it is characterised in that：Also include support 1, the both sides of the centre of the support 1 are respectively arranged with installation rotation
The through hole (being not drawn into figure) of axle 2, the two ends of the rotary shaft 2 are passed through is provided with screw thread (in figure not on the part of the through hole
Draw), it is fixed on by nut 7 on support 1, the fixed plate 3 of fixed water clock time set, institute is installed in the rotary shaft 2
That states fixed plate 3 is provided at both ends with through hole 9, and the fixing band 4 passes through through hole 9 from the front of fixed plate 3 respectively, passes through plug 10
The back side of fixed plate 3 is fixed on, the water clock time set is fixed on the front of fixed plate 3 by fixing band 4.In support 1
Portion sets rotary shaft 2 to be used for mounting plate 3, sets through hole 9 to be used to install fixing band 4 respectively in the upper and lower ends of fixed plate 3,
By fixing band 4 through the through hole 9 in fixed plate 3, to prevent fixing band 4 from coming off, the portion at the back side of fixed plate 3 is passed through in fixing band 4
Plug 10 is plugged on point, water clock time set is fixed on the front of fixed plate 3 with fixing band 4.Plug is removed when testing
10, water clock time set is placed on to the front of fixed plate 3, then plug plug 10.When needing to repeat demonstration water clock experiment, only need
Unscrew the nut 7 of fixed rotary shaft 2, water clock time set can be just inverted, again nut 7 be tightened after inversion by rotation fixed plate 3.
So as to can be carried out the timing experiment of dripping continuously repeated.
In the present embodiment：The fixed plate 3 is plank, and the rotary shaft 2 is to be set in stainless steel, the rotary shaft 2
Screwed hole (being not drawn into figure) is equipped with, the rotary shaft 2 and fixed plate 3 are linked together by screw 21.Connected with screw 21
