Abstract

一种底部设有真空吸盘的试管，主要由试管本体和设在试管本体底部的真空吸盘构成，能被大气压力压在桌面上不易倾倒而破损。

Description

底部设有真空吸盘的试管
技术领域 本发明涉及教学仪器，特别是涉及一种底部设有真空吸盘的试管。
背景技术 目前使用的试管，重心高，底盘小，不小心触碰容易倾倒，造成损坏或事故。
发明内容 本发明就是要提供一种底部设有真空吸盘的试管，它能在使用时靠底部的吸盘吸附在光滑的桌面上，不易因倾倒而造成损坏或事故。
本发明解决上述问题的技术方案如下：设计一种底部设有真空吸盘的试管，包括设有真空吸盘的底部和试管本体，其特征在于：试管本体的底部设有真空吸盘。
本发明的有益效果是：本发明通过实施以上技术方案，使得试管在使用过程中，通过真空吸盘对光滑桌面的吸附，增大了试管和光滑桌面之间的作用力，使试管不易倾倒造成损坏或事故。
附图说明
如图是本发明底部设有真空吸盘的试管的正视示意图。
由图中可看出，这种底部设有真空吸盘的试管，包括：真空吸盘1、试管本体2。
具体实施方式 使用中，手握试管本体2往下压，把设在底部的真空吸盘1压到光滑桌面上，真空吸盘1内的空气被排出，大气压力就会把真空吸盘1压在桌面上，从而使整个试管被固定在桌面上，不易被倾倒而破损。
