Abstract

本实用新型涉及一种变径量筒，包括底座和筒体，其特征在于：所述筒体由相互导通的上筒体和下筒体构成，所述上筒体的内径大于下筒体内径，且在上、下筒体外壁设有与筒体对应的容积刻度。本实用新型的优点在于：下筒体内径较小，在量取小量液体时，精确度较高；而在量取大量液体时，采用大内径上筒体和小内径下筒体的组合既保证了容积的同时，又避免完全采用小内径筒体造成的量筒过高问题，使用方便。

Description

一种变径量筒
技术领域
本实用新型涉及一种量筒，特别涉及一种变径量筒。
背景技术
量筒是用来量取液体体积的一种玻璃仪器，传统的量筒的筒体上下直径一致，量筒的容积越大，管径越粗，其精确度越小。在实验时，需要根据所取溶液的体积更换相应容量的量筒，很不方便。
实用新型内容
本实用新型要解决的技术问题是提供一种同时使用大、小容量液体的变径量筒，既可量取大容量的液体，又可在量取小容量液体的同时保证精确度。
为解决上述技术问题，本实用新型的技术方案为：一种变径量筒，包括底座和筒体，其特征在于：所述筒体由相互导通的上筒体和下筒体构成，所述上筒体的内径大于下筒体内径，且在上、下筒体外壁设有与筒体对应的容积刻度。
本实用新型的优点在于：下筒体内径较小，在量取小量液体时，精确度较高；而在量取大量液体时，采用大内径上筒体和小内径下筒体的组合即保证了容积的同时，又避免完全采用小内径筒体造成的量筒过高问题，使用方便。
附图说明
附图为本实用新型实施例变径量筒结构示意图。
具体实施方式
如附图所示，包括底座1、上筒体2a、下筒体2b。
上述底座1上设有筒体2，该筒体2由相互导通的上筒体2a和下筒体2b构成，上筒体2a的内径大于下筒体2b的内径，在上、下筒体2a、2b的外壁设有与筒体对应的容积刻度。
进行小容量液体量取时，由下筒体2b进行量取，精确度高，而量取大容量液体时，由下筒体2b和上筒体2a组合进行量取，使用方便。
