Description

Technical Field

[0001] This utility model relates to a measuring tape, specifically a measuring tape with a cleaning function. Background Technology

[0002] A measuring tape is a common distance measuring tool. When the working environment contains mud, sand, sawdust, iron filings, or other materials, these materials can stick to the tape. When the tape retracts automatically, it also retracts these materials into the tape case, which can lead to the following problems:

[0003] 1. When the ruler tape gets stuck to something and is being rolled up, the diameter of the ruler tape will increase as it is coiled on the ruler core. This causes the ruler tape to coil out of the ruler core and interfere with the ruler box, preventing the ruler tape from being completely rolled back into the ruler box.

[0004] Second, when the ruler tape gets stuck to something and is rolled up, it will bring these things into the ruler shell and fall into the ruler spring through the center hole of the ruler core, causing the snap ring to prevent the ruler tape from being completely retracted.

[0005] 3. When the measuring tape gets stuck to something and is wound up, there will be a coiling process when the measuring tape is wound up, which will scratch the display information on the surface of the measuring tape. After that, the display information on the surface will not be visible.

[0006] When you find mud, sand, wood chips, iron filings, or other debris stuck to the measuring tape during or after use, you need to find a suitable tool to clean it. If you don't clean it in time, it will soil your clothes if you carry it with you, or it will soil the storage box if you put it in. Summary of the Invention
