Abstract
The utility model provides a seismic recorder teaching aid, which is characterized in that: the seismic recorder teaching aid comprises a bracket; the bracket has two parallel beams with one in upper and one in lower and also a pillar connecting the two beams; the beams over the bracket suspends with a spring which has a record pen at end; the record pen is fixed on the pillar with another end; the beam below the bracket is installed with a winding drum record paper which is connected with an electric drive circuit; the record pen is contacted with the record paper. The utility model has the advantages of the simple structure and convenient utilization, which can visually explain the moving situation both in vertical and horizontal caused by earthquake, so as to reach the purpose of teaching through lively activities.
Description
Technical field
The utility model relates to a kind of teaching aid, particularly a kind of seismograph teaching aid.
Background technology
Earthquake is because the collision between the plate of the earth causes.When earthquake takes place, the ground that can take place laterally, motion longitudinally, and produce great sound wave, the result of damaging property.But, when giving these contents of student explain, lack visual in image teaching aid at present.
The utility model content
The purpose of this utility model is for a kind of seismograph teaching aid is provided.
A kind of seismograph teaching aid is characterized in that, comprises a support, and described support has two parallel beams up and down, and connects the column of two crossbeams; The crossbeam of the top of described support is hung with a spring, and the end of described spring has a recording pointer, and the other end of described recording pointer is fixed on the described column; One reel recording chart is installed on the crossbeam of described below, and described reel recording chart is connected with power driving circuit; And described recording pointer contacts with described recording chart is vertical.
The advantage of seismograph teaching aid of the present utility model is, and is simple in structure, easy to use, when explanation of seismic takes place visually, and the situation of vertical, the horizontal motion on the ground that causes, thus reach the purpose of teaching through lively activities.
Description of drawings
Fig. 1 is the synoptic diagram of seismograph teaching aid of the present utility model.
Embodiment
For the utility model is further described, illustrated below in conjunction with specific embodiment.
As shown in Figure 1, a kind of seismograph teaching aid 1 comprises a support, and described support has two parallel beams 2 and 3 up and down, and connects the column 4 of two crossbeams; The crossbeam 2 of the top of described support is hung with a spring 5, and the end of described spring 5 has a recording pointer 6, and the other end of described recording pointer 6 is fixed on the described column 4; One reel recording chart 7 is installed on the crossbeam 3 of described below, and described reel recording chart 7 is connected with power driving circuit; And described recording pointer 6 and described recording chart 7 vertical contacts.
Seismograph teaching aid 1 of the present utility model can be placed on the ground of subway process, in the time of the train process, open the power switch of reel recording chart 7, then spring 5 is owing to be subjected to the vibrations on ground, drive moving up and down of recording pointer 6 in succession, just on recording chart 7, made mark.Can calculate the shock conditions on ground according to the wave amplitude up and down of mark.
Certainly,, do not spend performing creative labour, on the basis of the foregoing description, can do multiple variation, can realize the purpose of this utility model equally for one of ordinary skill in the art.But above-mentioned various variations obviously should be at the protection domain of claim of the present utility model.
