Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0040] Such as Figure 1-10 As shown, a digital multifunctional ruler includes a housing 1 and a ruler wheel 2. The ruler wheel 2 is arranged inside the housing 1 and rotates on a central axis 11. A tape measure is also arranged on the ruler wheel 2. 21 and ruler spring 22; the displacement sensor counts the rotation of the ruler wheel 2; presses the ruler lock 3, and utilizes the elastic force of the elastic member to lock or unlock the telescopic position of the tape measure 21; power interface 401, display screen 402 and the PCB board 403 , the PCB board 403 is electrically connected with the display screen 402 , the displacement sensor and the power interface 401 .

[0041] Specifically, the above-mentioned displacement sensor adopts a Hall magnetic angle sensing chip 91, which converts the measurement data into the number of rotations, and corresponding...

Abstract

The invention discloses a digital multifunctional ruler which comprises a housing; a ruler wheel arranged in the housing, rotating about a central axis and provided with a flexible ruler and a ruler spring; a displacement sensor counting the rotation of the ruler wheel; a pressing ruler lock for locking or unlocking the stretching position of the flexible ruler in virtue of the elastic force of anelastic piece; and a display screen and a PCB which are electrically connected with the displacement sensor. The digital multifunctional ruler has the advantages of simple structure and reliable andstable structure, displays data on the display screen, and has digital functions of calculating and switching units.

Description

technical field [0001] The invention relates to the technical field of measuring tapes, in particular to a digital multifunctional ruler. Background technique [0002] At present, there are many kinds of laser digital rulers, but the laser digital ruler cannot measure the appearance data, and it does not have a calculation function. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a digital multifunctional ruler for the deficiencies of the above-mentioned prior art. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a digital multifunctional ruler, which includes a housing and a ruler wheel. A tape measure and a ruler spring are also arranged on the wheel; a displacement sensor counts the stretching length of the tape measure; press the ruler lock, and use the elastic force of the elastic member to lock or unlock the telescopic position o...
