Document Type and Number:
WIPO Patent Application WO/2018/228403
Kind Code:
A1
Abstract:
A device for measuring the remaining amount of a target material, comprising: a main body, which is provided with a plurality of measuring tracks that are arranged along a first direction, wherein each measuring track extends along a second direction, the second direction being perpendicular to the first direction; a plurality of ejector pins, which correspond one-to-one to the plurality of measuring tracks, each ejector pin extending along the second direction, and a first end of each ejector pin being limited within the measuring track corresponding thereto, wherein each ejector pin may move freely along the measuring track and may partly extend out from the measuring track; a plurality of sliding blocks, which correspond one-to-one to the plurality of measuring tracks, wherein each sliding block may be disposed within a measuring track so as to slide along the measuring track corresponding thereto, and each sliding block is limited to a side of a first end of an ejector pin, the static friction between each sliding block and measuring track being greater than the gravity thereof; and a main ruler, which is disposed on the main body and which is provided with scale lines that are arranged along the second direction. The measurement steps for the foregoing device for measuring the remaining amount of a target material are simple, and measurement results are accurate.
