Description
Technical field
The present invention relates to instruments used for education manufacturing technology field, especially a kind of toggle teaching teaching used is drilled
Display teaching aid.
Background technology
Toggle is the main movement mechanism in machine driving, applied in engine by the reciprocating motion of piston
It is changed into the rotary motion of bent axle, while the power that will act on piston is changed into the torque that bent axle is externally exported, to drive vapour
Car vehicle wheel rotation.When teacher explains the transmission principle of toggle using figure to student, student is difficult to imagination crank and connected
The design feature and purposes of linkage, the explanation of teacher can allow student to feel uninteresting, it is difficult to evoke learning interest.
The content of the invention
Problem to be solved by this invention is to provide a kind of demonstration teaching aid, allows student to get information about crank connecting link machine
The design feature and operation principle of structure, motivate students' interest in learning.
In order to solve the above problems, the technical solution adopted by the present invention is：This demonstration teaching aid, includes by two
Individual bearing block, which is arranged on the bent axle on demonstration board, the rod journal of the bent axle, is movably installed with connecting rod, the connecting rod and dress
Piston in cylinder sleeve is equipped with pull bar by hinge on the piston, the cylinder sleeve is fixed on described drill by support
Show on plate, flywheel is housed in one end of the bent axle, and the outer end of the flywheel is equipped with handle close to edge.
In above-mentioned demonstration teaching aid technical scheme, more specifically technical scheme can also be：In the side wall of the cylinder sleeve
It is provided with observation panel.
Further, the bearing block, the bent axle, the connecting rod, the piston, the cylinder sleeve and the flywheel by
Plastics are made.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
1st, the present invention can be exerted a force by pull bar to piston, and piston drives crank rotation by connecting rod, so that flywheel rotates,
Flywheel rotary motion is changed into by the linear motion of piston；Also rotatable handles, make flywheel drive crank rotation, pass through connecting rod band
Piston moves up and down, and is changed into the linear motion of piston by flywheel rotary motion.Student is allowed to get information about song by demonstration
The design feature and operation principle of handle linkage, motivate students' interest in learning.
2nd, observation panel is provided with the side wall of cylinder sleeve, is easy to observe the motion conditions of piston；Bearing block, bent axle, connecting rod, work
Plug, cylinder sleeve and flywheel are made of plastics, and are mitigated the weight of the demonstration teaching aid, are easy to carry.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is Fig. 1 left view.
Embodiment
With reference to specific embodiment, the invention will be further described：
A kind of demonstration teaching aid as shown in Figure 1 and Figure 2, includes the song being arranged on by two bearing blocks 1 on demonstration board 7
Connecting rod 3 is movably installed with axle 2, the rod journal of bent axle 2, connecting rod 3 is hinged with the piston 5 in cylinder sleeve 4 by bearing pin 6,
The major part of connecting rod 3 is connected with the rod journal of bent axle 2, and the microcephaly of connecting rod 3 is connected with piston 5, and dress is connected through a screw thread on piston 5
There is pull bar 9, cylinder sleeve 4 is fixed on demonstration board 7 by support 8, observation panel is offered on the side wall of cylinder sleeve 4.In bent axle 2
One end is equipped with flywheel 11, and the outer end of flywheel 11 is equipped with handle 10 close to edge.Bearing block 1, bent axle 2, connecting rod 3, piston 5, cylinder
Set 4 and flywheel 11 are made of plastics.
The present invention can be exerted a force by pull bar 9 to piston 5, and piston 5 is rotated by connecting rod 3 with dynamic crankshaft 2, so that flying
Wheel 11 is rotated, and the rotary motion of flywheel 11 is changed into by the linear motion of piston 5；Also rotatable handles 10, make flywheel 11 drive song
Axle 2 is rotated, and is moved up and down by connecting rod 3 with piston 5, is changed into the linear motion of piston 5 by the rotary motion of flywheel 11.Pass through
Demonstration allows student to get information about the design feature and operation principle of toggle, motivates students' interest in learning.
