Abstract
The utility model provides a guide rod mechanism demonstration teaching aid which comprises a first assembled rod, a second assembled rod, a third assembled rod and a sliding block, wherein one end of the first assembled rod is hinged with one end of the second assembled rod, the other end of the first assembled rod is hinged with one end of the third assembled rod, the other end of the third assembled rod is inserted in an inner hole of the sliding block to form a sliding pair, the side end of the sliding block is hinged with one end of the second assembled rod, and the first assembled rod, the second assembled rod and the third assembled rod are assembled by inserting adjusting rods 1 into adjusting rods 2. When the guide rod mechanism demonstration teaching aid is adopted, demonstrations on four guide rod mechanism teaching aids and one crank sliding block mechanism teaching aid can be completed on only one teaching aid; and the guide rod mechanism demonstration teaching aid has a simple structure and is convenient in disassembly and carrying.
Description
Technical field
The utility model relates to a kind of teaching aid, particularly a kind of mechanical teaching aid.
Background technology
In teaching process, for four kinds of guide-bar mechanisms---oscillating guidebar mechanism, whitworth mechanism, the fixedly demonstration of slide block mechanism, crank rocker mechanism and a kind of slider-crank mechanism, need use five different teaching aids.The teacher need go to class with the teaching aid of good several guide-bar mechanisms at school the time, because teaching aid is many, and can not dismantle again, brings very big inconvenience to teaching.
The utility model content
The technical problems to be solved in the utility model is to overcome existing defective, and a kind of guide-bar mechanism demonstration teaching aid is provided, and can demonstrate five kinds of different mechanism's forms by enough cover teaching aids, is convenient to teaching.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of guide-bar mechanism demonstration teaching aid comprises first compound rod, second compound rod, the 3rd compound rod and slide block; Described first compound rod, one end and second compound rod, one end are hinged, and the first compound rod other end and the 3rd compound rod one end are hinged, and the 3rd compound rod other end inserts the slide block endoporus and forms moving sets, and an end of the slider side end and second compound rod is hinged; The axial cavity that described first compound rod, second compound rod and the 3rd compound rod are No. two adjuster bars of an adjuster bar insertion combines.
Further, a described adjuster bar and No. two adjuster bars are fastenedly connected by screw.
Further, jug below the described slide block.
Further, the described slide block and second compound rod are hinged by screw axis; There is screw thread the upper end of described screw axis, forms with slide block to be threaded, and the lower end of screw axis is an optical axis, forms hinged with second compound rod.
A kind of guide-bar mechanism demonstration teaching aid of the utility model can be need four kinds of guide-bar mechanism teaching aids in the past by changing rod member length, and the demonstration that a kind of slider-crank mechanism teaching aid carries out is finished demonstration on a teaching aid.This teaching aid is simple in structure, can dismantle easily, is easy to carry.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, and constitutes the part of instructions, is used from explanation the utility model with embodiment one of the present utility model, does not constitute restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of guide-bar mechanism demonstration teaching aid of the utility model;
Fig. 2 is the schematic top plan view of a kind of guide-bar mechanism demonstration teaching aid of the utility model;
Fig. 3 is the local enlarged diagram of a kind of guide-bar mechanism demonstration teaching aid of the utility model.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.
As shown in Figure 1 and Figure 2, first compound rod 9, second compound rod 10, the 3rd compound rod 11 combine by an adjuster bar 1 and No. two adjuster bars 3.
An adjuster bar 1 is inserted in the axial cavity of No. two adjuster bars 3, and fastening through lock-screw 2, promptly constitute compound rod.An adjuster bar 1 of regulating the respective combination bar inserts the length in the adjuster bar 3, the i.e. length of this compound rod of scalable No. two.
One, the demonstration of oscillating guidebar mechanism: regulate the length of second compound rod 10, make the length of the length of second compound rod 10 greater than first compound rod 9.Fix first compound rod 9 with a hand, the another hand rotates second compound rod 10, makes second compound rod 10 around No. two axle 4 rotations, and the 3rd compound rod 11 is just done slip in the endoporus of slide block 6, slide block 6 is done the swing of certain angle, forms the demonstration of oscillating guidebar mechanism.
Two, the demonstration of whitworth mechanism: regulate the length of second compound rod 10, make the length of the length of second compound rod 10 less than first compound rod 9.Fix first compound rod 9 with a hand, the another hand rotates second compound rod 10, makes second compound rod 10 around No. two axle 4 rotations, and the 3rd compound rod 11 is just done slip in the endoporus of slide block 6, and complete cycle rotatablely moves the demonstration of formation whitworth mechanism.
Three, fixedly slide block mechanism demonstration: catch slide handle 8 with a hand, slide block 6 is maintained static, and an other hand is swung second compound rod 10, makes second compound rod 10 around screw axis 7 swings, the 3rd compound rod 11 is just done slip in the endoporus of slide block 6, form the fixedly demonstration of slide block mechanism.
Four, crank rocker mechanism demonstration: regulate the length of first compound rod 9, make the length of the length of first compound rod 9 less than second compound rod 10.Fix second compound rod 10 with a hand, the another hand rotates first compound rod 9, and first compound rod 9 is rotated around No. two axles 4, and the 3rd compound rod 11 is just done slip in the endoporus of slide block 6, slide block 6 is also done the swing of certain angle, forms the demonstration of crank rocker mechanism.
Five, slider-crank mechanism demonstration: regulate the length of first compound rod 9, make the length of the length of first compound rod 9 less than the 3rd compound rod 11.Fix the 3rd compound rod 11 with a hand, rotate first compound rod 9 with the another hand, first compound rod 9 is rotated around an axle 5, slide block 6 just slides on the 3rd compound rod 11, forms the demonstration of slider-crank mechanism.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
