Description

Technical Field

[0001] This utility model relates to the field of engineering measurement technology, and specifically refers to an integrated measuring ruler for indoor three-dimensional space measurement. Background Technology

[0002] In scenarios such as house inspection, interior design, and furniture placement, accurately measuring the width, depth, and height of a room is an essential step; currently, measuring tapes or laser rangefinders are commonly used for this purpose.

[0003] However, both measuring tapes and laser rangefinders suffer from low efficiency in obtaining data in three dimensions when measuring the width, depth, and height of a room. Specifically, they require multiple alignments and measurements in three directions, which undoubtedly consumes a lot of time. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an integrated measuring ruler for indoor three-dimensional space measurement, which solves the problem of low efficiency in multi-dimensional room measurement by conventional measuring devices in the prior art.

[0005] To achieve the above objectives, this utility model provides an integrated measuring ruler for indoor three-dimensional space measurement, used for simultaneous measurement of indoor bay width, depth, and net height; the measuring ruler includes three parallel main ruler rods, each of which is a telescopic structure and is provided with length graduations;

[0006] One end of each of the two main ruler rods is rotatably connected to each other via a first revolute joint;

[0007] The third main ruler rod at the same end is rotatably connected to either of the aforementioned two main ruler rods via a second revolute joint.

[0008] The axis of the first revolute joint is perpendicular to the axis of the second revolute joint.

[0009] When the measuring ruler is in the unfolded state, the three main ruler rods are perpendicular to each other in pairs.

[0010] By adopting this technical solution, three extendable main measuring rods are connected to form the measuring ruler. When unfolded, it corresponds one-to-one with the width, depth, and height of a room, allowing for simultaneous and continuous measurement of these three dimensions. This solves the problem of low measurement efficiency caused by the need for multiple positioning steps when using traditional measuring devices for multi-dimensional room measurements. The three main measuring rods form a stable spatial structure, enabling the entire measurement work to be completed without human assistance, thus reducing manpower requirements. Since the reference of the three main measuring rods originates from the same spatial coordinate system, the consistency of the starting point for the three dimensions of measurement is ensured, avoiding reference errors caused by multiple device movements. The rigid main measuring rod structure also overcomes the measurement error problem caused by the easy bending of measuring tapes. The measuring ruler can be quickly folded up after use, significantly reducing its size and making it easy to carry and store.

[0011] Furthermore, the measuring ruler also includes a locking knob, which is located on the main ruler rod and is used to lock the length of the main ruler rod after it has been extended or retracted.

[0012] By adopting this technical solution, firstly, the locking knob ensures the stability of the main scale rod length during the reading process, preventing unintended shrinkage or extension, thereby guaranteeing the accuracy and reliability of the measuring structure; secondly, it allows the measuring scale to adapt to rooms of different sizes, expanding its application range.

[0013] Furthermore, the measuring ruler also includes anti-slip contacts, which are respectively connected to both ends of the main ruler rod, and the surface of the side not connected to the main ruler rod is a serrated surface.

[0014] By adopting this technical solution, the anti-slip contact helps to accurately press the end of the main scale rod against the measuring surface, reducing measurement errors caused by slippage and improving operational stability and measurement accuracy.

[0015] Furthermore, both the first and second revolute joints include a rotating rod and a rotating sleeve that are rotatably connected to each other;

[0016] The rotating rod and rotating sleeve are respectively fixed on the two main ruler rods, and the two main ruler rods are rotated to each other through the mutual rotational connection of the rotating rod and rotating sleeve.

[0017] By adopting this technical solution, the rotating rod and the rotating rod form a simple, robust, durable and low-cost rotating connection, which is convenient for production and assembly.

[0018] Furthermore, the first and second rotary joints also include locking bolts;

[0019] The locking bolt is installed on the rotating sleeve and is used to lock the rotating sleeve and the rotating rod together when the two main ruler rods are adjusted to be vertical.

[0020] By adopting this technical solution, the locking bolts can lock the relative positions of the rotating rod and the rotating sleeve after the measuring scale is unfolded, thereby firmly locking the vertical relationship of the three main scale rods and forming a rigid measuring frame. This avoids errors caused by angle changes during operation and further ensures the stability of the three-dimensional spatial coordinate system during the measurement process, which is a key guarantee for achieving high-precision measurement.

[0021] Furthermore, the main measuring rod is equipped with an electronic reading display unit, which includes a microprocessor and a display screen, and is capable of automatically reading and displaying the length of the main measuring rod.

[0022] By adopting this technical solution, on the one hand, readings become more intuitive and convenient, avoiding parallax and misreading that may occur when reading scales with the naked eye, making it especially suitable for environments with poor lighting; on the other hand, it improves reading speed and accuracy, realizes the digitization and intelligence of measurement, and enhances user experience and measurement efficiency.

[0023] Furthermore, a level bubble level is installed on the main ruler rod.

[0024] By adopting this technical solution, the level bubble meter helps users ensure that the measuring ruler is placed horizontally. It is an important auxiliary measure to ensure that the height measurement is absolutely vertical and accurate, and improves the overall measurement accuracy and reliability from another dimension.

[0025] Compared with the prior art, this utility model has the following advantages:

[0026] 1. The measuring ruler is formed by three retractable main ruler rods connected to each other. When unfolded, it can correspond one-to-one with the room's width, depth, and height. This means that the room's width, depth, and height can be measured continuously and simultaneously, solving the problem of low measurement efficiency caused by the need for multiple positioning when performing multi-dimensional room measurements.

[0027] 2. Once the three main measuring rods are unfolded, they form a stable spatial structure, allowing all measurement work to be completed without the assistance of others, thus reducing the need for manpower.

[0028] 3. Since the reference of the three main measuring rods originates from the same spatial coordinate system, the uniformity of the measurement starting point in the three dimensions is ensured, avoiding the reference error caused by multiple movement of the device. The rigid main measuring rod structure also overcomes the measurement error problem caused by the easy bending of the measuring tape.

[0029] 4. The measuring ruler can be quickly folded up after use, greatly reducing its size and making it easy to carry and store. Attached Figure Description
