Description

Technical Field

[0001] The invention relates to the technical field of building measurement, in particular to a measuring instrument for building planning. Background Art

[0002] When doing home decoration and other work, it is usually necessary to plan and measure the interior architecture so that tiles or carpets can fit seamlessly. In buildings, walls inevitably have irregular edges, and it is difficult to use common measuring tools to accurately and quickly measure their angles and lengths, so that tiles and other building materials cannot fit perfectly with the wall corners when laid.

[0003] The patent with publication number "CN117288069A" discloses "an irregular wall angle measuring device, comprising a mounting seat, a plurality of measuring columns are slidably connected at equal intervals on the bottom of one side of the mounting seat, a connecting plate is fixedly connected to the bottom of the other side, a magnet column is fixedly connected to one end of the measuring column close to the connecting plate, a scanner is slidably connected to the top of the connecting plate away from the mounting seat, an iron sand tray for containing iron sand is arranged above the connecting plate, and a driving mechanism for driving the iron sand tray to move is arranged on the iron sand tray"; the end of the measuring column is pressed against the irregular wall corner for measurement, and the other end of the measuring column can make the iron sand form a corresponding track on the iron sand tray, and then the track is scanned by a scanner and imported into the computer, so that the shape of the irregular wall can be accurately and quickly copied and printed, and then tiles and other building materials can be cut according to the irregular shape of the track to achieve the effect of perfect fit with the wall corner.

[0004] Although the above technical solution can realize the measurement of irregular edges on the wall through several retractable measuring columns, there are still limitations in its use. First, after measuring the irregular edges through the measuring column, it is necessary to scan and copy the trajectory of the measuring column through a scanner, and then cut the tiles according to the printed trajectory, but it is not possible to quickly cut the tiles after measurement. The operation is cumbersome, the work continuity is poor, and it will lead to increased costs; in addition, although several measuring columns cooperate with each other to realize the measurement of irregular edges on the wall, the adjacent measuring columns cannot achieve a smooth transition, resulting in a jagged outline after measurement, causing the printed picture to be inaccurate, affecting the accuracy of tile cutting; in addition, it can only measure irregular edges through retractable measuring columns, and the function is relatively single. For this reason, we propose a measuring instrument for architectural planning to solve the above problems. Summary of the invention

[0042] As a further implementation scheme of the above invention: two groups of positioning mechanisms 5 are provided at one end of the mobile platform 1, and the positioning mechanism 5 includes a positioning screw 51 threadedly connected to the mobile platform 1 and a size indicating rod 52 movably connected to the mobile platform 1. Rotating the positioning screw 51 drives the size indicating rod 52 to move synchronously, and makes the end of the positioning screw 51 abut against the wall. The two groups of positioning mechanisms 5 cooperate with each other to assist in positioning the mobile platform 1, so that the curved edge measuring mechanism 3 is parallel to the wall as a whole, which is convenient for the sensor assembly 39 on the curved edge measuring plate 35 to detect the inclination of the wall.

The structure 3 is flipped around a group of guide rods 2, so that the curved edge measuring mechanism 3 is in a vertical state as a whole, and the curved edge measuring mechanism 3 is pushed to move, so that the curved edge measuring plate 35 is against the wall surface. A plurality of sensor components 39 are arranged on the curved edge measuring plate 35, and the push-pull force sensor 394 is against the wall surface and shrinks inwardly. The controller 8 receives the detection data of the plurality of sensor components 39.
