Fig. 3 be the utility model proposes a kind of mechanics apparatus for demonstrating partial structural diagram.
Specific embodiment
As shown in Figures 1 to 3, Fig. 1 be the utility model proposes a kind of mechanics apparatus for demonstrating structural schematic diagram, Fig. 2 is
The utility model proposes a kind of mechanics apparatus for demonstrating side structure schematic view, Fig. 3 be the utility model proposes a kind of power
Learn the partial structural diagram of apparatus for demonstrating.
Referring to figs. 1 to 3, the utility model proposes a kind of mechanics apparatus for demonstrating, comprising: installation wall 1, at least one drills
Show unit;
Demonstration unit is located at the side of installation wall 1, and demonstration unit includes driving motor, support rod 3, at least one is O-shaped
Circle 4, support rod 3 is horizontally set on driving motor and one end and is fixedly connected with the drive shaft of driving motor, and O-ring 4 is set in
Outside support rod 3, driving motor drives support rod 3 to rotate by drive shaft.
In a specific embodiment, each demonstration unit includes multiple O-rings 4, and multiple O-rings are sequentially sleeved at support rod
It is external.
In the specific work process of the mechanics apparatus for demonstrating of the present embodiment, driving motor drives support rod rotation, in gravity
Under the action of frictional force, O-ring is around driving support rod rotation;Since there are error, O-ring and branch for O-ring itself
The original state of strut is not absolute upright state, thus spectators are able to observe that O-ring under frictional force and the resultant force of gravity
Moving along support rod occurs, so that spectators are able to observe that the effect between O-ring and support rod and adjacent O-ring
Power and reaction force reach science popularization purpose, improve science popularization effect.
In the present embodiment, the mechanics apparatus for demonstrating proposed, demonstration unit are located at the side of installation wall, demonstration unit
Including driving motor, support rod, multiple O-rings, support rod is horizontally set on the drive of on driving motor and one end and driving motor

Reasonable in design by the mechanics apparatus for demonstrating of above-mentioned optimization design, multiple O-rings are set in outside flexible pipe, with soft
The rotation of property pipe, under the influence of frictional force, inertia and gravity, due to O-ring weight and original state tilt angle not
Together, so that spectators observe that O-ring is axially moveable on flexible pipe, to be visually observed that active force and reaction force etc.
Newton's law improves science popularization effect.
In a specific embodiment, demonstration unit includes the first driving motor 21 and the second driving motor 22, the first driving
Motor 21 and the second driving motor 22 are oppositely arranged and the two drive shaft is located on same level straight line, 3 both ends of support rod difference
It is fixed in the drive shaft of the first driving motor 21 and the second driving motor 22, by the way that driving electricity is respectively set at support rod both ends
