Abstract
The utility model provides a seismograph for teaching. A seismograph which is invented in ancient time can not do action until the earthquake happens. The utility model comprises a seismograph and eight openmouthed toads, wherein the seismograph and the eight openmouthed toads are positioned on a bottom board which is in a downwards convex shape. When the utility model is used, the measuring state of the seismograph in earthquake can be simulated at any moment. When the utility model is used for teaching demonstration, the understanding degree of the seismograph by students can be enhanced.
Description
The utility model relates to a kind of teaching shows and drills apparatus.
Seismograph is that Chinese Han is towards scientist Zhang Heng, in 132 years Christian eras inventions, it comprises the main body of a bulging teacup with cover of outer image, body surfaces is cast with eight dragons, Long Zui is movable, every dragon all contains a ball in the mouth, and all post and eight roads are installed in the main body, and all post is a upper coarse and lower fine rod, play the effect of shake pendulum, eight roads are located at all around the post on eight directions, and link to each other with mechanical driving device, and other has eight frogs of opening one's mouth.Seismograph is positioned on the ground, and tap is aimed at east, south, west, north, the southeast, northeast, southwest, eight directions in northwest, and eight frogs of opening one's mouth squat down on the ground facing to Long Zui.During teaching, can only explain, can not simulate when earthquake takes place the measurement live telecast of seismograph according to picture.
The purpose of this utility model is to provide a kind of Seismograph for teaching that can demonstrate the course of action of seismograph, to improve the understanding effect to seismograph.
The purpose of this utility model is achieved in that it comprises seismograph and eight frogs of opening one's mouth, and seismograph and eight frogs of opening one's mouth all place on the base plate, and base plate is convex down.
Advantage of the present utility model is: seismograph and eight frogs of opening one's mouth are positioned on the protruding down base plate, as long as on a direction of base plate, give a shaking force, all posts of seismograph will be toppled over to stressed direction, drive the mechanical driving device of this direction, the Long Zui that drives this direction opens, and the ball in this dragon mouth will fall into the corresponding frog mouth of opening one's mouth.Measurement effect when earthquake takes place in simulation.Demonstrate with device of the present utility model in the teaching, can deepen the understanding of student to seismograph, device of the present utility model not only can be as a kind of desirable teaching demonstration apparatus, also be a kind of artwork ornaments of fineness, help developing ethnic cultures, strengthen national confidence, excite teen-age patriotic enthusiasm.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the upward view of Fig. 1.
For example the utility model is done more detailed description below in conjunction with accompanying drawing:
In conjunction with Fig. 1, seismograph is by main body 8, and loam cake 3 places all posts 1, eight roads 2, mechanical driving device 7 in the main body, is positioned at eight dragons 4 of body surfaces, places the ball 6 in the imperial mouth to form.Seismograph places the middle part of base plate 9, eight open one's mouth frog 10 respectively with eight imperial corresponding placing on the base plate, base plate is down convex.Effect when in order to simulate earthquake taking place can be placed again more stablely, and the following convex that base plate is can be is inverted eight mill dell shapes.
It can be to fixedly connected that seismograph and eight open one's mouth between frog and the base plate.Thisly fixedly connectedly relatively be fit to small-sized instrument or as artwork ornaments.
It also can be to flexibly connect that seismograph and eight open one's mouth between frog and the base plate, so that whole packing, transport and deposit.In movable connection structure, can have seismograph and eight frog location and installation grooves of opening one's mouth on the base plate, so that make that assembling is more convenient, accurate.
All post can be a kind of eight stupefied posts, the corresponding mechanical driving device of each face of eight stupefied posts.This all posts can be so that move accurate.
