Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building engineering technology, and specifically relates to a verticality detection device for building engineering. Background Technology
[0002] Construction engineering refers to the engineering entity formed through the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Buildings refer to structures with roofs, beams, columns, walls, foundations, and internal spaces that meet people's needs for production, residence, study, and public activities. Verticality testing is a crucial step in ensuring the stability and construction quality of building structures. Verticality testing involves measuring the vertical direction of a building or structure to verify whether it maintains a correct 90° angle. The purpose of testing is to ensure that the building structure remains upright in the vertical direction, avoiding excessive verticality deviations that could affect the stability and safety of the structure. Currently, verticality testing uses a measuring ruler, which is opened to 90 degrees and placed against the building wall for measurement. However, due to the lack of limiting mechanisms after opening, both hands are needed to maintain the ruler's vertical position. This is inconvenient when performing batch verticality measurements. Therefore, the inventor proposes a verticality testing device for construction engineering. Utility Model Content
[0003] (1) Technical problems to be solved
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a verticality detection device for building engineering, which aims to solve the problem that the existing technology lacks a limit after opening, requires the assistance of both hands to keep the detection ruler in a vertical state, and is not convenient to operate when batch verticality measurement is required.
[0005] (2) Technical solution
[0006] To address the aforementioned technical problems, this utility model provides a verticality testing device for building engineering, comprising a fixed ruler, a movable ruler, and a limiting block. The fixed ruler has a recessed receiving groove at its upper surface, into which the movable ruler is embedded and rotatably connected. The movable ruler has a magnetic strip on its rotating surface facing the receiving groove, and the receiving groove contains a metal sheet adapted to the magnetic strip. A handle is installed on the outer wall of the fixed ruler, and a protrusion is provided on the side wall of the fixed ruler near the connecting end of the movable ruler, with a limiting block installed on the protrusion. A limiting insertion hole is formed on the side wall of the movable ruler, and the limiting block movably adapts to the limiting insertion hole. Thanks to the embedded design of the movable and fixed rulers, the device saves space when folded and is easy to carry. When the movable ruler is unfolded, it is held in place by the limiting block, allowing the fixed ruler to be lifted using the handle for easy operation. During batch verticality testing, there is no need to hold both the fixed and movable rulers with both hands, effectively improving measurement convenience.
[0007] Preferably, the protrusion has a mounting hole, the limiting block is adapted to the mounting hole for installation, and the inner wall of the mounting hole has a sliding groove.
[0008] Preferably, a slider is provided protruding on the outer wall of the limiting block, the slider is adapted to the slide groove, a spring is installed in the slide groove, and the slider is adapted to the spring.
[0009] Preferably, a rotating shaft protrudes from the outer wall of the movable ruler, the rotating shaft being rotatably connected to the fixed ruler, and the rotating shaft passing through the fixed ruler.
[0010] Preferably, a convex shaft is fixed at the end of the rotating shaft away from the movable ruler, the convex shaft and the rotating shaft are co-centered, and a pointer is fixed on the outer wall of the convex shaft.
[0011] Preferably, an outer cover plate is fixedly installed on the outer wall of the fixed ruler. The outer cover plate has a hollow structure and covers the outside of the convex shaft. The convex shaft and the outer cover plate are co-centered.
[0012] Preferably, the surface of the outer cover has scale lines distributed around it.
[0013] (3) Beneficial effects
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] This utility model benefits from the embedded design of the movable and fixed rulers, saving more space when folded and making it easier to carry. When the movable ruler is unfolded, it can be fixed to the fixed ruler by the setting of the limiting block. At this time, the fixed ruler can be lifted by the handle, which is convenient for operation. When performing batch perpendicularity tests, there is no need to hold the fixed ruler and the movable ruler with both hands, which effectively improves the convenience of measurement and operation. After the test is completed, the limiting block can be pulled, and the end of the limiting block will leave the limiting hole, and the movable ruler can be released from the limit. Then, the movable ruler can be flipped inward toward the fixed ruler to complete the storage. It is highly practical and can be widely promoted. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] This specific embodiment is a verticality detection device for building engineering, and its structural schematic diagram is shown below. Figure 1 , Figure 2As shown, it includes a fixed ruler 1, a movable ruler 7, and a limiting block 6. The fixed ruler 1 has a recessed receiving groove 3 on its upper part, and the movable ruler 7 is embedded in the receiving groove 3. The movable ruler 7 is rotatably connected to the fixed ruler 1. The surface of the movable ruler 7 that flips towards the receiving groove 3 has a magnetic strip, and the inside of the receiving groove 3 has a metal sheet that is adapted to the magnetic strip. A handle 2 is installed on the outer wall of the fixed ruler 1, and a protrusion 8 is provided on the side wall of the fixed ruler 1 near the connecting end of the movable ruler 7. The limiting block 6 is installed on the protrusion 8.
[0024] Reference Figure 3 , Figure 4 The movable ruler 7 has a limiting hole 17 on its side wall, and the limiting block 6 is movably adapted to the limiting hole 17. The protrusion 8 has a mounting hole 13, and the limiting block 6 is adapted to the mounting hole 13. The inner wall of the mounting hole 13 has a sliding groove 12. A slider 10 protrudes from the outer wall of the limiting block 6, and the slider 10 is adapted to the sliding groove 12. A spring 11 is installed in the sliding groove 12, and the slider 10 is adapted to the spring 11. A rotating shaft 14 protrudes from the outer wall of the movable ruler 7, and the rotating shaft 14 is rotatably connected to the fixed ruler 1, and the rotating shaft 14 passes through the fixed ruler 1. A convex shaft 15 is fixed at the end of the rotating shaft 14 away from the movable ruler 7. The convex shaft 15 and the rotating shaft 14 are concentrically distributed, and a pointer 16 is fixed on the outer wall of the convex shaft 15. An outer cover plate 5 is fixedly installed on the outer wall of the fixed ruler 1. The outer cover plate 5 is a hollow structure and covers the outside of the convex shaft 15. The convex shaft 15 and the outer cover plate 5 are distributed concentrically. The surface of the outer cover plate 5 has scale lines 4 distributed around it.
[0025] Working principle: In use, first rotate the movable ruler 7 out from the inside of the fixed ruler 1. The fixed ruler 1 and the movable ruler 7 are magnetically fixed. After the movable ruler 7 is unfolded, the pointer 16 can be observed. The pointer 16 rotates synchronously with the fixed ruler 1. By observing the rotation angle of the pointer 16 on the scale line 4, the unfolded value of the movable ruler 7 can be obtained. When the movable ruler 7 is unfolded to 90 degrees, the limiting block 6 can be inserted into the limiting insertion hole 17. At this time, the movable ruler 7 and the fixed ruler 1 are fixed. The fixed ruler 1 can be lifted by the handle 2 for easy operation.
