Abstract

The invention discloses a tape measure, which includes: a casing, a reel, and a tape; the tape measure also includes: a laser distance measuring device, which can measure the target distance by emitting a detection beam parallel to the first direction; the laser distance measuring device includes: a laser source, Generating laser beams; optical circuit components, at least enabling the laser beams generated by the laser source to be used as the detection beam of the laser distance measuring device; photoelectric conversion elements, capable of converting optical signals into electrical signals; power supply, contained in the housing, at least powering the laser source; The optical path assembly at least further includes: a turning optical element, which can at least turn the reflected light parallel to the first direction formed by the detection beam reflected by the object to a direction parallel to the second direction; the turning optical element is located between the laser source and the photoelectric conversion element between. The tape measure of the present invention is equipped with a laser distance measuring device, has a reasonable size and can measure a relatively distant 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...
