Abstract

The invention discloses physics teaching buoyancy testing equipment which comprises a heavy article, a spring-loaded thrust meter, a container as well as a lifting device, wherein the container is used for containing a liquid; the lifting device comprises a base, a mounting rod, a support rack, a first driving component and a mounting tank; the bottom end of the support rack is connected with the base; two ends of the mounting rod are respectively and detachably connected with the support rack; a pulley is arranged on the mounting rod; the mounting tank is arranged on the base; the first driving component is arranged on the mounting tank; the first driving component comprises a first rotating shaft, a wire coil and a first rocker handle; the wire coil is fixed on the first rotating shaft; the first rotating shaft is rotationally arranged in the mounting tank; one end of the first rotating shaft penetrates through the mounting tank shell wall and is detachably connected with the first rocker handle; a connecting rope is connected with the top of the spring-loaded thrust meter; the other end of the connecting rope bypasses the pulley and is connected with the wire coil. In the testing process, the spring-loaded thrust meter does not shake horizontally, so that data can be displayed relatively stably, testing results can be relatively accurate, and relatively good testing data repeatability is achieved.

Description

technical field

[0001] The present invention relates to a kind of buoyancy experiment equipment, more specifically relates to a kind of buoyancy experiment equipment for physics teaching. Background technique

[0002] The buoyancy experiment is a basic experiment that middle school students should understand and master. The law of buoyancy of objects, also known as Archimedes’ law, according to Archimedes’ principle, objects immersed in liquid are subject to upward buoyancy, and the magnitude of buoyancy is equal to the displacement of objects The gravity of liquid is a very important law in physics. In teaching, this law is relatively abstract and difficult to understand. In order to deepen understanding, teachers often make various teaching aids to calculate the liquid discharged by objects. The teaching aids used generally include heavy objects, beakers, water receiving containers, and spring dynamometers. In the actual operation process, due to the unprofessional tools u...
