Drawing tape with suction cup

Abstract

The invention discloses a drawing tape with a suction cup. The tape comprises a shell, a ruler strip and a roller, wherein the suction cup is arranged on the shell, the ruler strip is arranged in theshell, a rotating shaft is arranged at the tail end of the shell, and a layer of fluorescent powder and a protective film are arranged on the ruler strip; a through hole is formed in the ruler strip,and a plug rod matched with the through hole is arranged on the roller; the shell is further provided with a protection pad. The tape has the advantages that the tape has basic functions and can alsobe used for drawing circles with different diameters; the roller ensures that the required circles are stably drawn; the suction cup is arranged on the shell of the tape so that the tape can be absorbed and fixed to an objected through the suction cup in use, and the problem that it is inconvenient for a single person to use a tape is solved; besides, the fluorescent layer is arranged on the surface of the ruler strip so that the tape can be used in the environment with poor light; scales on the tape can be read conveniently, whether the tape is attached to a measured object or not can be accurately judged, and measurement results can be guaranteed.

Description

Technical field [0001] The invention relates to the field of electric tools, in particular to a drawing tape measure with a suction cup. Background technique [0002] As early as the Ming Dynasty, my country’s famous mathematician, abacus, and inventor Cheng Dawei invented the world’s first tape measure "measuring walker". With the development of technology, tape measures have become smaller and smaller and more convenient. Carry and use. [0003] Tape measures often need to be used together with other tools. Currently, tape measures with a single function on the market often cannot meet the increasing demands of consumers. [0004] The tape measure is very convenient to carry and use. Many people use the tape measure when measuring the length of the object. However, because the tape measure can be wound, the tape measure must be used by a person to pull the ruler body. It is difficult for a single person to fix it. The tape measure is used normally. [0005] It is difficult to read ...

AI Technical Summary

Problems solved by technology

[0003] Tape measures often need to be used together with other tools. Currently, tape measures with a single function on the market often cannot meet the increasing needs of consumers.

[0004] The tape measure is very convenient to carry and use. Many people will use the tape measure when measuring the length of the object. However, the tape measure can be wound up, so that the ruler body must be pulled by one person during use, and it is difficult for a single person to fix it. tape measure in normal use

[0005] When used in an environment with poor lighting, the scale on the tape measure is difficult to read, and it is impossible to accurately judge whether the tape measure fits the object under test, which directly affects the measurement result
