Wear-resistant electric tape with suction cup

Abstract

The invention discloses a wear-resistant electric tape with a suction cup. The electric tape comprises a casing body, a tape bar, a tape bar disk and a direct current motor. The suction cup is arranged on the casing body. A control switch is arranged on the upper end of the casing body. The tape strip disk is arranged in the casing body. A power supply battery is arranged in the casing body. The tape bar is wound on the tape bar disk. A protective film is arranged on the tape bar. An output shaft is arranged on the direct current motor. A cylindrical gear is arranged at the end part of the output shaft. A transmission gear which is integrated with the tape bar disk is arranged at the central part of one side of the tape bar disk. The cylindrical gear at the end part of the output shaft ofthe direct current motor is meshed with the transmission gear. According to the invention, the electric tape has the advantages of simple structure, convenient manufacture, low manufacture cost, spacesaving and long service life; expansion and contraction of the tape bar can be conveniently controlled by the control switch, which is convenient for use; the protective film is arranged on the tapebar; the wear resistance of the tape bar is improved; the suction cup is arranged on the casing body of the tape; in use, the tape is fixedly adsorbed on an object for use through the suction cup; andthe problem that the tape is inconvenient for a single person to use in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to a wear-resistant electric tape measure with a suction cup. Background technique [0002] The measuring tape is a commonly used measuring tool in daily life. What we often see is the steel tape. It is commonly used in the construction and decoration industry, and it is also one of the necessary tools for families. The tape measure can be rolled up because there is a spring inside the tape measure. When pulling out to measure the length, it actually lengthens the length of the ruler and the spring. Once the measurement is completed, the spring inside the tape will automatically shrink, and the ruler will be under the action of the spring force. It also shrinks, so the measuring tape rolls up. Existing ordinary tape measures usually require two hands to operate, one hand holds the housing, the other hand pulls out the tape, and after use, the tape is rolled up under the retu...

AI Technical Summary

Problems solved by technology

Existing ordinary tape measures usually require two hands to operate, one hand holds the housing, the other hand pulls out the tape, and after use, the tape is rolled up under the return action of the spring. The operation of this tape measure It is inconvenient to operate with both hands. When measuring a long object, the hand cannot control the head of the ruler because it is beyond the reach of the hand. If there is a slight carelessness, the ruler will automatically wind up, which affects the Measurement process
