Abstract
The utility model provides a force assembly and disassembly demonstrating instrument, which belongs to a steady and precise demonstrating instrument. The demonstrating instrument conducts an experiment by two circular chutes and a pulley thereon. The demonstrating instrument is connected with a weight and a dynamometer to view the degrees in the dial to conduct the force assembly and disassembly demonstrating experiment.
Description
Technical field
The utility model is about a kind of teaching aid, refers to the synthetic of a kind of power especially and decomposes demonstrator.
Background technology
In physics teaching, when talking about the synthetic of mechanics and decomposing, in order to allow the student deepen intuitivism apprehension, often adopt the method for demonstration, its demenstration method normally earlier marks force vector, and then the synthetic decomposition of this power is drawn on chart board with illustrated mode on chart board, this method, obviously directly perceived inadequately.For demonstrator more intuitively, at present usually usefulness have two kinds, a kind of is said experiment instrument on the textbook, it is 90 situations when spending that this experiment instrument can only be demonstrated two component, function singleness; Another kind of experiment instrument need be pulled out earlier and be made a concerted effort, go out arrow along this direction of making a concerted effort with stroke then and represent its direction, again with representing its direction with pen along the direction of two component arrow that draws after two power actings in conjunction, this experiment instrument, can not demonstrate the dynamic change relation of power, steadiness and degree of accuracy are relatively poor during use.
Summary of the invention
Fundamental purpose of the present utility model provides the synthetic of a kind of power and decomposes demonstrator.
For reaching above-mentioned purpose, the utility model provides the synthetic of a kind of power and decomposes demonstrator, it is characterized in that comprising:
One panel which is provided with a circular scale, and two arc chutes concentric with described circular scale are set, and described chute surrounds whole index dial.
Further improvement of the utility model is: be provided with pulley in the described arc chute.
Further improvement of the utility model is: but described panel below is provided with the base for supporting of height up and down.
Further improvement of the utility model is: described arc chute is symmetry mutually.
Further improvement of the utility model is: described circular scale has 360 evenly divideds.
Further improvement of the utility model is: described circular scale circular arc is divided into four arcs by level and vertical diameter, and the scale of horizontal diameter and circular arc intersection point is 90 degree, and vertically diameter and circular arc intersection point are 0 to spend.
Further improvement of the utility model is: the described circular scale center of circle overlaps with the arc chute center of circle.
By above technical scheme, synthetic and the decomposition demonstrator of the firm and accurate power that the utility model provides, it provides higher steadiness, adopt the index dial of multi-angle to improve degree of accuracy simultaneously, make original experiment instrument use the relatively poor problem of steadiness and degree of accuracy and obtained good solution.Of the present utility model acting as tested image and accurate more synthesizing and decomposing of can exerting all one's strength, and has higher steadiness, thereby avoids problems of the prior art.

Embodiment
See also shown in Figure 1ly, be the synthetic of the utility model power and decompose the floor map of a preferred embodiment of demonstrator, wherein as can be seen the utility model power synthetic and decompose demonstrator mainly include following each partly:
One panel 1 which is provided with a circular scale 11, and this index dial 11 is positioned at the center of panel 1, and is divided into 360 down scales, centre point 111; Article two, arc chute 12 and 13 with described circular scale 11 concentric settings, described arc chute is greater than semicircle and symmetry up and down, arc chute 12 and 13 opening direction are opposite; Be provided with pulley 121 and pulley 122 in the arc chute 12; Be provided with pulley 131 in the arc chute 13;
One supports underframe 2, is positioned at panel 1 below.
Fig. 2 is the synthetic of the utility model power and decomposes experiment one synoptic diagram of a preferred embodiment of demonstrator, as shown in the figure: be enclosed within on the pulley 121 with bungee 31 1 ends, one end is by fine rule 32,33 link to each other with dynamometer 41 and 42, make the other end of bungee 31 place centre point 111 places, position by observing reading on the dynamometer and the pairing scale of fine rule can deterministic force angle and size, carry out the synthetic of power and decompose lecture experiment.
Fig. 3 is the synthetic of the utility model power and decomposes experiment two synoptic diagram of a preferred embodiment of demonstrator, as shown in the figure: connect counterweight 61 with fine rule 51 1 ends, the other end links to each other with 53 with fine rule 52, fine rule 52 and 53 is walked around pulley 131 respectively and is linked to each other with 63 with counterweight 62 with 122, and the intersection point of three fine rules is overlapped with centre point 111, by the number of observation counterweight 61,62 and 63 and the position of fine rule 52 and 53, carry out the synthetic of power and decompose lecture experiment.
Fig. 4 is the synthetic of the utility model power and decomposes experiment three synoptic diagram of a preferred embodiment of demonstrator that as shown in the figure: a fine rule 71 1 ends link to each other with dynamometer 43, the other end and fine rule 72, an end of 73 links to each other, the other end of fine rule 72,73 and dynamometer 41,42 link to each other, and the intersection point of 3 lines is overlapped with centre point 111, by observing the reading and the fine rule 72 of dynamometer 43,44,45,73 position is carried out the synthetic of power and is decomposed lecture experiment.
Said apparatus by pulley 121,122 and 131 with being connected of dynamometer or counterweight, can be arbitrarily made with the experimental demonstration that different device carries out, the simple use, and demonstration that can the image effect that go out to test.
