Description
Technical field
The utility model belongs to education or demonstration equipment field, is specifically related to a kind of physical teaching aid.
Background technology
In physics, a lot of physical equation is dry as dust, and is not easy to memory, and student gets up to lose interest in especially in study.Teaching aid is as a kind of model, and a kind of instrument, can well adjust the interest of Students ' Learning physical knowledge.In physics, the object be positioned on slope is subject to self gravitation and the inclined-plane support normal power to physics and the effect of friction force, and object is static or do accelerated motion under the effect of these three power.
Utility model content
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, the utility model provides that a kind of structure is simple, easy to carry, tilt adjustable be mainly used in explanation object at the combined type physical teaching aid of inclined-plane stressing conditions, improve quality of instruction.
Basis is practical to be newly achieved through the following technical solutions:
Physical teaching aid, comprises base and angel measuring instrument, and angel measuring instrument is arranged on one end of base; Be provided with groove below base, be provided with roller devices in groove, roller devices is fixed on the one end in groove by rotating shaft; Mobile jib is provided with above base, mobile jib is connected to the initial point place of angel measuring instrument by rotating shaft, slot is provided with above mobile jib, vertical and the mobile jib in the direction of slot, below mobile jib, slot correspondence position is provided with peg, physical teaching aid also comprises auxiliary bar-I, auxiliary bar-II and connection cord, auxiliary bar-I one end is inserted in slot, auxiliary bar-II one end is provided with hook-II, size and the peg of hook-II match, connection cord one end is provided with hook-I, and size and the peg of hook-I match, and the other end of connection cord is provided with medicine ball.
Mobile jib, auxiliary bar-I and auxiliary bar-II is provided with scale, the stressing conditions of convenient explanation object on dip plane.
The quantity being arranged on slot and peg on mobile jib is 2 ~ 20, so just can explain the stressing conditions that object is in mobile jib diverse location place.
When the utility model uses, rotate mobile jib and rest on predetermined angle place by it, test articles is placed on the slot side of mobile jib, then suitable auxiliary bar-I and auxiliary bar-II is selected, auxiliary bar-I is inserted in slot, auxiliary bar-I is perpendicular to mobile jib, auxiliary bar-II is hung on the peg below the slot of auxiliary bar-I place by hook-II, now auxiliary bar-II naturally droops due to Action of Gravity Field, mobile jib, auxiliary bar-I and auxiliary bar-II are provided with scale mark, so can the stressing conditions of object analysis on dip plane intuitively.If directly rotate mobile jib to rest on predetermined angle place by it, the roller devices be hidden in base groove is taken out, connection cord is hung by hook-I at peg place, then with hand, medicine ball is loosed one's grip after roller devices rotating direction shifts certain altitude onto, medicine ball is vacillated now to the left, now to the right under gravity and inertia effect, will drive base side-to-side movement; When medicine ball is static, base gets back to original position, can explain law of conservation of energy.
Compared with prior art, the utility model has following beneficial effect:
The utility model structure is simple, easy to carry, mobile jib tilt adjustable, can be used for explanation object inclined-plane stressing conditions and law of conservation of energy, is convenient to observation of students and teacher's explanation, improves quality of instruction.
Accompanying drawing explanation
Mark in the content expressed each width accompanying drawing of the utility model instructions below and figure is briefly described:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model junction structural representation.
In figure: 1, base, 2, angel measuring instrument, 3, roller devices, 4, groove, 5, auxiliary bar-I, 6, auxiliary bar-II, 7, mobile jib, 8, medicine ball, 9, connection cord, 10, hook-I, 11, hook-II, 12, peg, 13, slot.
Embodiment
Contrast accompanying drawing below, by the description to optimum embodiment, embodiment of the present utility model is described in further detail.
Physical teaching aid as shown in Figure 1 and Figure 2, comprise base 1 and angel measuring instrument 2, angel measuring instrument 2 is arranged on one end of base 1, be provided with groove 4 below base 1, be provided with roller devices 3 in groove 4, roller devices 3 is fixed on the one end in groove 4 by rotating shaft, mobile jib 7 is provided with above base 1, mobile jib 7 is connected to the initial point place of angel measuring instrument 2 by rotating shaft, mobile jib 7 is provided with slot 13 above, slot 13 direction is perpendicular to mobile jib 7, below mobile jib 7, slot 13 correspondence position is provided with peg 12, physical teaching aid also comprises auxiliary bar-I5, auxiliary bar-II6 and connection cord 9, auxiliary bar-I5 one end is inserted in slot 13, auxiliary bar-II6 one end is provided with hook-II 11, size and the peg 12 of hook-II 11 match, connection cord 9 one end is provided with hook-I 10, size and the peg 12 of hook-I 10 match, connection cord 9 other end is provided with medicine ball 8.
