Practical gravity detection device based on physics laboratory

Abstract

The invention relates to the technical field of a physics laboratory device and particularly relates to a practical gravity detection device based on a physics laboratory. The gravity detection devicecomprises a base plate, wherein a support pillar is fixedly connected with one side of the top of the base plate; a support rod is inserted into the top of the support pillar; a support plate is fixedly connected with the top of the support rod; a first hook is fixedly connected with the bottom of the support plate at the side away from the support rod; a dynamometer is in lap joint with the bottom of the first hook; a force measurement rod is movably connected with the dynamometer; a threaded sleeve is in threaded connection with the bottom of the force measurement rod; a second connection plate is fixedly connected with the bottom of the threaded sleeve; a second hook is fixedly connected with one side of the bottom of the second connection plate; a third connection plate is fixedly connected with the bottom of the second connection plate at the side away from the second hook; and a clamp is fixedly connected with the front face of the third connection plate. According to the gravity detection device, conventional measurement weights can be measured conveniently through utilization of the second hook; the gravity measurement can be carried out on clampable objects through utilization of the clamp; and diversity of gravity experiment measurement objects is increased.

Description

technical field [0001] The invention relates to the technical field of physics laboratory devices, in particular to a practical gravity detection device based on a physics laboratory. Background technique [0002] A physics laboratory is a place for physical science activities and inquiries. It can be divided into two types: demonstration laboratory and group laboratory. Group laboratories should be allocated according to grades. According to teaching needs and school conditions, the above two types of laboratories can be set up or combined. [0003] Gravity detection is a relatively basic experiment in junior high school physics experiments. Generally, the dynamometer is placed on the shelf, and weights of different weights are placed at the bottom of the dynamometer to measure gravity. However, the existing physical gravity detection The device can detect few items, and most of them can only detect weights with hanging rings fixed on the top, and the weights are generall...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a practical gravity detection device based on a physical laboratory, which solves the problem that the existing physical gravity detection device can detect fewer items, and most of them can only detect weights with hanging rings fixed on the top. Weights, and the weights are generally marked with weight marks, which reduces the fun of gravity testing and is not conducive to increasing students' interest in learning physics
