For realizing the utility model object, the technical scheme of employing is: a kind of crank apparatus for demonstrating for imparting knowledge to students, it is characterized in that, and comprise model support, described model support is provided with fixed bearing block; On described fixed bearing block, be hinged with crank, one end of crank is connected with power set, 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, between plain bearing housing and model support, is provided with fastener.
Further, described locking device comprises the rotating shaft being positioned on connecting rod, and rotating shaft and rocking bar are hinged, and clamp nut has been threaded in rotating shaft.
Further, described fastener comprises the slide bar being positioned on plain bearing housing, and described model support is provided with the chute matching with slide bar.
Further, the twisting handle that has been threaded on described slide bar.
Further, described power set comprise the driving wheel being positioned on crank, and driving wheel is connected with motor.
Further, between described driving wheel and motor, be belt connection for transmission.
Employing the utlity model has following advantage:
1, the application is incorporated into one above demonstrating model by crank rocker and slider-crank mechanism, can carry out by shirtsleeve operation the function conversion of demonstrating model, realize the Multifunctional demonstration of demonstrating model, increase the practical efficiency of model, convenient teacher's teaching demonstration, is conducive to improve classmate's learning interest.
Brief description of the drawings
Fig. 1 is a kind of structural representation for the crank apparatus for demonstrating of imparting knowledge to students that the utility model provides;
Fig. 2 is that a kind of A for the crank apparatus for demonstrating of imparting knowledge to students of providing of the utility model is to view.
Detailed description of the invention
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Fig. 1 and Fig. 2 have shown a kind of structural representation for the crank apparatus for demonstrating of imparting knowledge to students, and it is characterized in that, comprise model support 1, described model support 1 is provided with fixed bearing block 3; On described fixed bearing block 3, be hinged with crank 4, one end of crank 4 is connected with power set, and power set 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, between plain bearing housing 10 and model support 1, is provided with fastener.
Locking device comprises the rotating shaft 7 being positioned on connecting rod 5, and rotating shaft 7 is hinged with rocking bar 8, and the clamp nut 6 that has been threaded in rotating shaft 7, while locking, forms a connecting rod between clamp nut 6 is by connecting rod 5 and rocking bar 8; When clamp nut 6 is during in relaxed state, between connecting rod 5 and rocking bar 8, can relatively rotate.
Fastener comprises the slide bar 14 being positioned on plain bearing housing 10, and described model support 1 is provided with the chute 11 matching with slide bar 14, when fastener at loosening situation drop shot 14 in the interior slip of chute 11, serve as slide block; When fastener is in the situation that locking, plain bearing housing 10 is fixed on above model support 1, serves as fixing bearing block.
On slide bar 14, be threaded and twisted handle 9, twisting handle 9 matches with slide bar 14 screw thread above, and the rotation of twisting handle 9 can fastening plain bearing housing 10.
