Abstract
The utility model relates to an appearance is demonstrated to elasticity for physical teaching, including barrel, rubber band, connecting rod, disc, tray, weight ball, its characterized in that: at the fixed rubber band that is provided with in the opening part both ends of barrel, be provided with the gasket of cuboid at the intermediate position of rubber band, be provided with the iron ball in the gasket the inside, being provided with the cuboid through -hole of erectting on the lateral wall of barrel, being provided with the connecting rod of cuboid in through -hole the inside, be provided with the recess A of cuboid at the lower extreme of connecting rod, recess A sets up the both sides at the through -hole lower extreme, be provided with the disc in the one end of connecting rod, be provided with the tray of square at the other end of connecting rod, intermediate position at the tray is provided with circular shape recess B, has placed the weight ball inside recess B. The beneficial effects of the utility model are that: according to the tensile size of rubber band, accurate calculation elasticity size and the relation that the throwing object distance leaves can quantify the operation, more can deepen understanding and the teaching effects of student to physics classroom teaching.
Description
Technical field
The utility model relates to a kind of physics teaching teaching aid, is specifically related to a kind of elasticity demonstration instrument for physics teaching.
Background technology
In prior art, when physics teaching, the elastic force of spring and the relation demonstration of distortion also do not have display instrument directly perceived, and teacher is abstract explanation, and student accepts difficulty, and teaching efficiency is poor.
Utility model content
The purpose of this utility model be more abstract for the demonstration of existing elasticity demonstration instrument for physics teaching, can not the deficiency such as quantization operation, provide a kind of can specifically demonstrate elastic force, can the elasticity demonstration instrument for physics teaching of quantization operation.
The purpose of this utility model is realized by following technological means: a kind of elasticity demonstration instrument for physics teaching, include cylindrical shell, bungee, connecting link, disk, pallet, counterweight ball, it is characterized in that: described cylindrical shell is a kind of right cylinder, there is a circular open in the upper end of cylindrical shell, be fixedly installed bungee at the opening part two ends of cylindrical shell; Described bungee is a kind of rectangular parallelepiped, and the two ends of bungee are separately fixed at the opening part two ends of cylindrical shell, be provided with the pad of rectangular parallelepiped, inside pad, be provided with iron ball in the centre position of bungee; The sidewall of cylindrical shell is provided with the rectangular parallelepiped through hole of setting, is provided with the connecting link of rectangular parallelepiped inside through hole, be provided with the groove A of rectangular parallelepiped in the lower end of connecting link, groove A is arranged on the both sides of through hole lower end; One end of connecting link is provided with disk, and disk is also arranged on the inner side of cylindrical shell; The pallet of square is provided with at the other end of connecting link; Described pallet is the square that a kind of rigid plastic makes, and is provided with circular groove B, is placed with counterweight ball inside groove B in the centre position of pallet.
The beneficial effects of the utility model are: this elasticity demonstration instrument for physics teaching is placed on the lower end of pad by iron ball, then utilize hand that bungee is up pulled, move certain height to, then let go, iron ball can beat the upper end at disk, disk moves down, at this moment the counterweight club up impelling inside groove B is placed on, according to the size of bungee pulling force, the relation of accurate calculating elastic force and parabolic distance, can quantization operation, more can deepen student to the understanding of Physics Classroom Teaching and teaching efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
