Test device for bearing pressure of egg shell structure

Abstract

The invention provides a general technology teaching test device for bearing pressure of an egg shell structure. According to the device, a pressure rod is arranged by utilizing a level principle, and a moveable egg pressing groove and a special hook weight which are matched are utilized, so that qualitative experimental study can be carried out on the bearing pressure of the egg shell structure conveniently, the test operation is simple and precise, and test consumable items are less.

Description

Technical field [0001] The invention relates to a shell structure bearing pressure test device, in particular to a general technical teaching test device capable of qualitatively studying the egg shell structure bearing pressure. Background technique [0002] At present, in general high school general technical compulsory 2 "Understanding Structure" and "Inquiry Structure" teaching, there are only "small tests" of "egg bearing pressure test", and there is generally a lack of qualitative shell structure bearing pressure test research devices and demonstration test instruments . Summary of the invention [0003] The invention provides a pressure test device for egg shell structure, which uses the principle of lever to set a pressure rod, uses a movable egg pressing groove and a special hook code to facilitate qualitative testing of the egg shell structure under pressure Research, test operation is simple and accurate, and test consumables are few. [0004] The technical solution ado...
