Description
Technical field
It the utility model is related to instruments used for education manufacturing technology field, especially a kind of toggle teaching religion used
Learn demonstration 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 externally exports, to drive vapour
Car vehicle wheel rotation.When teacher explains the transmission principle of toggle using figure to student, student is difficult to imagine that crank connects
The design feature and purposes of linkage, the explanation of teacher can allow student to feel uninteresting, it is difficult to evoke learning interest.
Utility model content
Problem to be solved in the utility model is to provide a kind of demonstration teaching aid, allows student to get information about crank company
The design feature and operation principle of linkage, motivate students' interest in learning.
To solve the above-mentioned problems, the technical solution adopted in the utility model is：This demonstration teaching aid, includes logical
Bent axle of two bearing blocks on demonstration board is crossed, connecting rod, the connecting rod are movably installed with the rod journal of the bent axle
It is hinged with the piston in cylinder sleeve by axis pin, push-pull rod is housed on the piston, the cylinder sleeve is fixed by the bracket in institute
State on demonstration board, flywheel is housed in one end of the bent axle, the outer end of the flywheel is equipped with handle close to edge.
In above-mentioned demonstration teaching aid technical solution, more specifically technical solution can also be：In the side wall of the cylinder sleeve
It is equipped 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 utility model has the advantages that compared with prior art：
1st, the utility model can exert a force piston by push-pull rod, and piston drives crank rotation by connecting rod, so that
Flywheel rotates, and is changed into flywheel rotary motion by the linear motion of piston；Also rotatable handles, make flywheel drive crank rotation,
Piston up-down is driven by connecting rod, is changed into the linear motion of piston by flywheel rotary motion.Make student straight by demonstration
The design feature and operation principle of the understanding toggle of sight, motivate students' interest in learning.
2nd, observation panel is equipped with the side wall of cylinder sleeve, 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 mitigate the weight of the demonstration teaching aid, easy to carry.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model embodiment.
Fig. 2 is the left view of Fig. 1.
Embodiment
With reference to specific embodiment, the utility model is described in further detail：
A kind of demonstration teaching aid as shown in Figure 1 and Figure 2, includes and is installed on by two bearing blocks 1 on demonstration board 7
Bent axle 2, connecting rod 3 is movably installed with the rod journal of bent axle 2, connecting rod 3 is cut with scissors with the piston 5 in cylinder sleeve 4 by axis pin 6
Connect, 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, is connected on piston 5 by screw thread
Tipping has push-pull rod 9, and cylinder sleeve 4 is fixed on demonstration board 7 by stent 8, and observation panel is offered on the side wall of cylinder sleeve 4.In song
One end of axis 2 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
5th, cylinder sleeve 4 and flywheel 11 are made of plastics.
The utility model can exert a force piston 5 by push-pull rod 9, and piston 5 is rotated by connecting rod 3 with dynamic crankshaft 2, so that
Flywheel 11 is rotated, 11 rotary motion of flywheel is changed into by the linear motion of piston 5；Also rotatable handles 10, make 11 band of flywheel
Dynamic crankshaft 2 rotates, and is moved up and down by connecting rod 3 with piston 5, is changed into the linear motion of piston 5 by 11 rotary motion of flywheel.
Allow student to get information about the design feature and operation principle of toggle by demonstration, motivate students' interest in learning.
