Problems solved by technology

There are the following shortcomings in use: 1. It is inconvenient or even impossible to measure some flexible, curved or circumferential measured objects
2. The scale is polluted and cannot be used
3. It cannot be used in some special environments, such as when some parts of the measured object block the scale and cannot move the scale to read again, that is, blind spot measurement

Abstract

The invention relates to a multifunctional electronic tape, which comprises a shell, a wire-pulling distance measurement device, a liquid crystal display, a PCB and a battery, wherein the liquid crystal display is embedded in the shell, the PCB and the battery are fixed in the shell, the PCB is provided with a single-chip microcomputer, the wire-pulling distance measurement device comprises a wire pulling head, a wire and a wire winding device, the shell is further fixedly provided with two guide columns at the corners, one end of the wire is wound on the wire winding device, the other end of the wire sequentially bypasses the two guide columns and then penetrates out from one corner of the shell, the other end of the wire is fixed with the wire pulling head with a magnet, and the shell is further internally provided with an optical image sensor at the position between the two guide columns. According to the invention, multiple functions are integrated, the multifunctional electronic tape can be independently used, the measured length is displayed in the mode of a numerical value, the trouble of scale reading is saved, the measurement precision is higher than that of a traditional steel tape, he measurement error is less than 1mm, and intelligent tape data can be transmitted to a mobile phone in real time through an APP so as to be convenient for recording and consulting.

Description

technical field [0001] The invention belongs to the field of measuring tools, in particular to a multifunctional electronic tape measure. Background technique [0002] At present, the structure of the known tape measure is that a metal or non-metal tape with a scale is wound into a metal or non-metal box, and the length of the object to be measured is read by the scale on the tape. There are the following deficiencies in use: 1. It is inconvenient or even impossible to measure some flexible, curved or circular objects to be measured. 2. The scale is polluted and cannot be used. 3. It cannot be used in some special environments, such as when some parts of the measured object block the scale and cannot move the scale to read again, that is, blind spot measurement. In addition, in the published patents, the bulletin number is 2175408-unscaled super-constant steel tape measure; the bulletin number is 1181496-electric digital display tape measure and electric electronic counter...
