Utility model content
The utility model is for the defect of prior art, and be intended to propose a kind of structure simple, demonstration is convenient, can improve the teaching aid that student understands mechanics principle.
The utility model solves the problems of the technologies described above by the following technical solutions: a kind of mechanical teaching aid, comprises support, two fixed pulleys, light rope, the first bucket, the second bucket and suspender.Described support comprises base, supports scale bar and fixing scale bar, described support scale bar is vertically fixed on base, one end of described fixing scale bar is fixedly connected with support scale bar, and the other end of described fixing scale bar is free end, and on described fixing scale bar, cover has two activity box.Described two fixed pulleys are arranged on the side of described two activity box respectively.Described light rope strides across two fixed pulleys, and one end of described light rope connects described first bucket, and the other end of described light rope connects described second bucket.Described suspender comprises the light rope of hook, the 3rd bucket and hook, and described hook one end of gently restricting connects described 3rd bucket, and described hook is gently restricted other end coupling hook, and described hook is suspended on described light rope.
Preferably: the surface of described two fixed pulleys is provided with lubricating layer.
Preferably: described fixing scale bar is vertical with described support scale bar.
Preferably: described first bucket, the second bucket and the 3rd bucket certainly focus in 100g.
Preferably: the upper limit of the charging capacity of described first bucket, the second bucket and the 3rd bucket is 500g.
Preferably: described in hook into the distance of two fixed pulleys equal.
Preferably: the quality of described hook is not more than 10g.
Preferably: the quality of described light rope is not more than 10g.
Preferably: the quality that described hook is gently restricted is not more than 10g.
The utility model is by changing the displacement of the weight of the first bucket or the second bucket, the first bucket or the time of the second bucket vertical movement and the vertical movement of the first bucket or the second bucket respectively, demonstration displacement, acceleration and time relation each other; By being suspended on the light rope between two fixed pulleys by the 3rd bucket, demonstrate the relation between the size of component and component angle by changing gently rope and the angle hung between light rope.
The utility model has the advantage of: structure is simple, demonstration is convenient, improves student to the understanding of mechanics principle, mainly applies to the application of mechanical teaching aid.
Accompanying drawing explanation
Fig. 1 is the structural drawing of a kind of mechanical teaching aid of the utility model.
Fig. 2 is the local structural graph fixing scale bar in Fig. 1 in mechanical teaching aid.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1-2, the utility model embodiment provides a kind of mechanical teaching aid, comprises support 1, two fixed pulleys 2, gently to restrict the 3, first bucket 4, second bucket 5 and suspender 6.The deadweight of described light rope 3 is preferably 5g, and the deadweight of the first bucket and the second bucket is preferably 50g.Described support comprises base 11, supports scale bar 12 and fixing scale bar 13, described support scale bar 12 to be vertically fixed on base 11, one end of described fixing scale bar 13 is fixedly connected with support scale bar 12, and the other end of described fixing scale bar 13 is free end.Described fixing scale bar 13 is provided with two activity box 131, and described two activity box 131 are all enclosed within fixing scale bar 13.Described two fixed pulleys 2 are arranged on the side of two activity box 131 respectively.Described light rope 3 strides across two fixed pulleys 2, and one end of light rope 3 connects described first bucket 4, and the other end connects the second bucket 5.Described suspender 6 comprises the light rope 63 of hook 61, the 3rd bucket 62 and hook, and the deadweight of described hook 61 is preferably 5g, and the deadweight of the 3rd bucket 62 is preferably 50g, and the deadweight of the light rope of hook is preferably 5g.Described hook 63 one end of gently restricting connect the 3rd buckets 62, described hook gently restrict 63 other end coupling hook 61, described hook 61 is suspended on light rope 63.
The utility model embodiment is by supporting top and the terminal of marker motion on scale bar 12, change the weight of the first bucket 4 or the second bucket 5, observe the first bucket 4 or the second bucket 5 and move to the marked terminal time used from the top of mark, displacement one timing is worked as in demonstration, the relation of acceleration and time; By supporting the top of marker motion on scale bar 12 and determining the weight of the first bucket 4 and the second bucket 5, change the terminal of motion, observe the first bucket 4 or the second bucket 5 moves to the different terminals desired time, demonstration when acceleration one timing, the relation of displacement and time; By determining the top of run duration and marker motion, change the weight of the first bucket 4 or the second bucket 5, observe the displacement that the first bucket 4 or the second bucket 5 move within the identical time from the top of mark, demonstration when the time is certain, the relation of acceleration and displacement; By adding a certain amount of water respectively in the first bucket 4, second bucket 5 and the 3rd bucket 62, ensure that the weight of the first bucket 4, second bucket 5 and the 3rd bucket 62 is identical, then the 3rd bucket 62 is suspended on light rope 3 by hook 61, and make the distance of the 3rd bucket 62 to two fixed pulleys 2 equal, mobile two fixed pulleys 2 change light rope 3 and hang the angle of gently restricting between 63 again, demonstration makes a concerted effort one regularly, the size of component and the relation of component angle.
