Description

Foldable right-angle measuring scale

Technical Field

The utility model relates to a measuring tool technical field, the more specifically collapsible rectangular dipperstick that says so.

Background

In life, people often need to measure the length of some objects or structures, and a plurality of measuring tools are needed. Traditional dipperstick divides many categories, but the function is all comparatively single, most all have rectilinear measurement's function, and what use in the in-service use most often is the right angle measurement, the length of two perpendicular lines of simultaneous measurement, including house engineering survey, water and electricity construction and furniture wooden work etc., need multiple measurement to cooperate jointly just can accomplish at ordinary times, current dipperstick can not satisfy daily user demand, and probably influence the measuring accuracy degree, and, because traditional ruler length is limited, it is too long to lead to the unable condition on the earth of measuring to appear the measuring distance very often, therefore, need design a degree of accuracy height and can solve this problem by long distance measuring's right angle dipperstick.

In order to measure the distance of a certain point in a right-angle range conveniently, the Chinese patent (No. CN 209181789U) discloses a portable measuring ruler for surveying and mapping of constructional engineering, wherein a T-shaped convex block is installed on one side of a first measuring ruler and a second measuring ruler, a sliding block is arranged on the T-shaped convex block, a guide groove is formed in one side of the sliding block, a lifting rope is installed in the guide groove, a lead weight is installed at the other end of the lifting rope, a level gauge is arranged inside the second measuring ruler, a pattern groove is formed in the second measuring ruler, ruler scale marks are arranged on the first measuring ruler and the second measuring ruler, circular sleeves are arranged at one ends of the first measuring ruler and the second measuring ruler, the first measuring ruler and the second measuring ruler are connected through a rotating installation mechanism, and the rotating installation mechanism is composed of a rotating installation column and a rotating installation cover. The utility model discloses a lead to carrying inconvenient problem because of needing multiple measuring tool when having solved the building engineering measurement, have the benefit that the practicality is strong.

The scheme still has some shortcomings in application, and the problem that the conventional scales with longer measuring distance cannot be measured often exists in the measuring process, wherein the conventional scales comprise the length and the height, and meanwhile, the two measuring scales can fall off by adopting the conventional threaded connection. Therefore, there is a need for improvements and additions to the structure and function of measuring straightedges that enable measuring longer distances and that are more portable.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a collapsible rectangular dipperstick, its main aim at overcomes the above-mentioned not enough and shortcoming that prior art exists.

The utility model adopts the technical scheme as follows:

the utility model provides a collapsible rectangular dipperstick, includes that first measurement ruler, second measure ruler, infrared distance meter and standing groove, the left end inboard of first measurement ruler is equipped with circular recess, and this circular recess is built-in to have an internal thread, the second is measured the ruler and is corresponded the lower extreme outside and be equipped with circular joint, and this circular joint lateral surface is equipped with the external screw thread, first measurement ruler with the second is measured the ruler and is passed through the internal thread with the external screw thread closes perpendicularly articulated soon, first measurement ruler with all be provided with ruler scale mark on the ruler is measured to the second, the standing groove rigid coupling in first measurement ruler right side is terminal, infrared distance meter adaptation inlays to be located the standing groove.

Furthermore, an expansion spring is arranged on one inward side of the inner side of the placing groove, a clamping block is arranged at the tail end of the expansion spring, and the clamping block is matched and clamped with the infrared range finder.

Furthermore, a first opening and a second opening are respectively arranged on one outward side of the placing groove, and the first opening and the second opening respectively correspond to a display screen and a control switch of the infrared distance measuring instrument.

Furthermore, a circle internal thread is arranged at the bottom of the inner side of the circular groove, a circle external thread is correspondingly arranged at the tail end of the circular joint, and the circle external thread is correspondingly clamped with the circle internal thread.

Furthermore, a level gauge is arranged on the outer side surface of the circular groove.

Furthermore, the second measuring ruler can be folded along the first measuring ruler through screwing of the external thread and the internal thread.

Through the above-mentioned right the utility model discloses a description compares with prior art, the advantage of the utility model lies in:

the utility model discloses at first measure ruler and second through setting up perpendicular articulated first measurement ruler, and the lateral surface all is equipped with the ruler scale mark, be convenient for measure the distance to the point of ruler scale mark within range, circular recess lateral surface is provided with the spirit level simultaneously, can improve measuring precision, then, first measurement ruler right side end is equipped with the standing groove, the clamp is equipped with the outer distancer of red line in the standing groove, can measure the distance to the point far away, also can overturn and measure the distance to higher point, further improve ranging rod's multifunctionality, and finally, collapsible and first measurement ruler coincidence when the second measurement ruler is idle, do not account for space and portable, the utility model discloses simple structure and novelty is applicable to some house engineering and measures, construction and furniture woodwork etc..
