For realizing the object of the invention, the technical scheme of employing is: a kind of crank apparatus for demonstrating for imparting knowledge to students, and it is characterized in that, comprise model support, described model support is provided with fixed bearing block; Described fixed bearing block is hinged with crank, and one end of crank is connected with propulsion system, and the other end is hinged with connecting rod, and rod hinge connection has rocking bar; The hinged place of described connecting rod and rocking bar is provided with locking device, and the end of rocking bar is hinged with plain bearing housing; Described plain bearing housing is slidably arranged on model support and the bottom of plain bearing housing is provided with scroll wheel, is provided with fastener between plain bearing housing and model support.
Further, described locking device comprises the rotating shaft be positioned on connecting rod, rotating shaft and rocking bar hinged, rotating shaft has been threaded clamp nut.
Further, described fastener comprises the slide bar be positioned on plain bearing housing, and described model support is provided with the chute matched with slide bar.
Further, described slide bar has been threaded twisting handle.
Further, described propulsion system comprise the driving wheel be positioned on crank, and driving wheel is connected with motor.
Further, between described driving wheel and motor be belt connection for transmission.
Tool of the present invention is adopted to have the following advantages:,
1, crank rocker and slider-crank mechanism are incorporated into above a demonstrating model by the application, the function conversion of demonstrating model can be carried out by shirtsleeve operation, achieve the Multifunctional demonstration of demonstrating model, add the practical efficiency of model, the teaching demonstration of convenient teacher, is conducive to the learning interest improving classmate.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of crank apparatus for demonstrating for imparting knowledge to students provided by the invention;
Fig. 2 is the A direction view of a kind of crank apparatus for demonstrating for imparting knowledge to students provided by the invention.
Embodiment
Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.
Fig. 1 and Fig. 2 illustrates a kind of structural representation of the crank apparatus for demonstrating for imparting knowledge to students, and it is characterized in that, comprises model support 1, and described model support 1 is provided with fixed bearing block 3; Described fixed bearing block 3 is hinged with crank 4, and one end of crank 4 is connected with propulsion system, and propulsion system can drive crank 4 to rotate on fixed bearing block 3, and the other end is hinged with connecting rod 5, and connecting rod 5 is hinged with rocking bar 8; Described connecting rod 5 is provided with locking device with the hinged place of rocking bar 8, and the end of rocking bar 8 is hinged with plain bearing housing 10; Described plain bearing housing 10 is slidably arranged on model support 1 and the bottom of plain bearing housing 10 is provided with scroll wheel 12, is provided with fastener between plain bearing housing 10 and model support 1.
Locking device comprises the rotating shaft 7 be positioned on connecting rod 5, and rotating shaft 7 is hinged with rocking bar 8, and rotating shaft 7 has been threaded clamp nut 6, when clamp nut 6 is by when locking between connecting rod 5 and rocking bar 8, forms a connecting link; When clamp nut 6 is in relaxed state, can relatively rotate between connecting rod 5 and rocking bar 8.
Fastener comprises the slide bar 14 be positioned on plain bearing housing 10, and described model support 1 is provided with the chute 11 matched with slide bar 14, when the situation drop shot 14 that fastener is loosening slides in chute 11, serves as slide block; When fastener is when locking, plain bearing housing 10 is fixed on above model support 1, serves as fixing bearing seat.
Slide bar 14 has been threaded twisting handle 9, and twisting handle 9 matches with the screw thread above slide bar 14, and the rotation of twisting handle 9 can fastening plain bearing housing 10.
