Problems solved by technology

Existing measuring instruments are cumbersome and time-consuming to carry. Some hand-held rangefinders need to be accurately aimed at the target, but it is difficult to find a target that can reflect accurately in the wild
However, human visual inspection often has too much error

Embodiment Construction

[0024] The present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention.

[0025] Such as Figure 1-5 The portable multifunctional measuring instrument shown includes a first sight tube 1, a second sight tube 2 and an arc angle ruler 4,

[0026] One end of the first sight tube 1 is movably connected to one end of the second sight tube 2,

[0027] One end of the arc-shaped angle ruler 4 is hinged to the middle of the second sight tube 2 through the connecting button 203, and the concave side of the arc-shaped angle ruler 4 faces the movable connection point of the first sight tube 1 and the second sight tube 2.

[0028] The arc-shaped angle ruler 4 is provided with an arc-shaped sliding bar mouth 402 extending along the length of the arc-shaped angle ruler 4, and a sliding control knob 102 is provide...

Abstract

The invention discloses a portable multifunctional measuring apparatus which comprises a first visual tube (1), a visual tube (2) and an arc-shaped angle ruler (4). One end of the first visual tube (1) is movably connected with one end of the visual tube (2), one end of the arc-shaped angle ruler (4) is hinged to the middle of the visual tube (2), the concave side face of the arc-shaped angle ruler (4) faces the movably connecting position of the visual tube (1) and the visual tube (2), an arc-shaped sliding strip opening (402) extending in the length direction of the arc-shaped angle ruler (4) is formed in the arc-shaped angle ruler (4), and a sliding control rotary knob 102 is arranged in the middle of the visual tube (1) and is in sliding fit with the arc-shaped sliding strip opening (402). The portable multifunctional measuring apparatus can roughly measure the height of a target object (contour line), a distance from the apparatus to the target object, the distances from a surface slope to two target objects and the like and is light, simple and direct.

Description

Technical field [0001] The invention relates to the technical field of field observation instrument manufacturing, in particular to a portable multifunctional measuring instrument. Background technique [0002] Field scientific observation often needs to determine the general height and distance of the target, such as the height of the sand dune, the distance to the target, and the distance between two sand dunes. Existing measuring instruments are relatively cumbersome and time-consuming to carry. Some handheld rangefinders need to be accurately aligned with the target, but it is difficult to find a target that can accurately reflect in the field. The manual visual inspection often has too large errors. Summary of the invention [0003] In view of the shortcomings of the prior art, the present invention proposes a portable multifunctional measuring instrument, which can roughly measure the height of the target (contour line), the distance to the target, the slope of the ground a...
