Abstract

The invention discloses a measuring tape which comprises a housing, a scroll and a blade. The measuring tape further comprises a laser ranging device, which can emit a detection light beam parallel to a first direction to measure a target distance; a laser source, generating a laser beam; a light path assembly, which at least can enabling the laser beam generated by the laser source to act as the detection light beam of the laser ranging device; a photoelectric conversion element, which can convert a light signal into an electric signal; and a power supply, accommodated in the housing to at least supply power for the laser source. The light path assembly further comprises a turning optical element, which at least can turn reflective light that is parallel to the first direction and formed after the detection light beam is reflected by an object to be along a direction parallel to a second direction. The turning optical element is located between the laser source and the photoelectric conversion element. The measuring tape is provided internally with the laser ranging device, is reasonable in size and can measuring a relatively far target distance.

Description

technical field [0001] The invention relates to a distance measuring device, and specifically designs a measuring tape with a laser distance measuring device. Background technique [0002] As an existing commonly used distance measuring device, the tape measure is limited by the external dimensions of the tape measure, and the length of the measuring tape inside it is limited, which is limited by the external dimensions, so it can only measure a limited distance. Difficulties encountered in some cases where the target distance needs to be measured. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a tape measure with reasonable size and capable of measuring the distance of a far target. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A tape measure comprising: [0006] shell; [0007] The scroll is housed in the...
