Embodiment Construction

[0020] Such as Figure 1-3 As shown, the present invention provides a technical solution: a simulation device for physical elasticity teaching in junior high schools, including a vertical board 1, the bottom of the vertical board 1 is fixedly connected with a horizontal bottom board 2, and the left and right sides of the vertical board 1 are fixedly connected with side panels. Both sides of the front of the plate 3 and the vertical plate 1 are provided with vertical areas 4, and the tops of the two vertical areas 4 are fixedly connected with rectangular clamp rings 5 ​​by bolts, and the inner walls of the two rectangular clamp rings 5 ​​are bonded with clamp airbags 6. The two clamp airbags 6 are bonded with a friction plate 7 on the side away from the rectangular clamp ring 5. The cross-sectional shape of the rectangular clamp ring 5 is rectangular, and the shape of the clamp airbag 6 is similar to that of the inner wall of the rectangular clamp ring 5. , the clamp airbag 6 i...

Abstract

The invention relates to the technical field of teaching equipment, and discloses a simulation device for elasticity teaching in junior middle school physics. The device includes a vertical plate, thebottom of the upright plate is fixedly connected with a transverse bottom plate, the left and right sides of the vertical plate are fixedly connected with side plates, Both sides of the front face ofthe vertical plate are provided with vertical areas, the top of the two vertical areas are fixedly connected with rectangular fixture rings by bolts, the inner side walls of the two rectangular fixture rings are bonded with fixture air bags, the two fixture air bags are bonded with friction plates on the side far away from the rectangular fixture rings, and the air guide ports of the two fixtureair bags are fixedly connected with air ducts. The simulation device for elasticity teaching in junior middle school physics, thus can be aimed at different length of spring dynamometer connection force measurement, so that teachers or students can test different spring dynamometer for the same tension at the same time, to obtain different spring coefficient of spring dynamometer, reduce the errorof the result.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a simulation equipment for teaching physical elasticity in junior high schools. Background technique [0002] In junior high school physics teaching, in the chapter about the spring dynamometer, teachers generally use the spring dynamometer to pull the weight to weigh the weight, so that students can more easily accept the relevant teaching, but this teaching method is relatively simple , Different spring dynamometers pull and measure the weight of the same weight, and may get different tension values, with a large tension error. However, in junior high school physical elasticity teaching, there are few tests for different spring dynamometers. The teaching equipment can obtain the spring coefficient of spring in the spring dynamometer, so a simulation equipment for junior high school physics teaching is needed to test the tension of different spring dynamometers to obt...
