Description

Technical Field

[0001] This utility model relates to the field of measurement technology for building construction, and specifically to a measurement device for building construction. Background Technology

[0002] During the construction process, it is necessary to measure and calculate the construction site. By further analyzing the measurement data, it is easier for construction personnel to formulate an accurate construction plan. In the process of formulating the plan, tools are needed to measure the angle of the walls.

[0003] For example, the publication (announcement) number CN213208838U discloses a measuring instrument for building construction, including a cylindrical rod, a telescopic rod movably connected inside the cylindrical rod, a measuring plate hinged to the top of the telescopic rod via a shaft, a sliding opening on one side of the measuring plate, a vernier plate on one side of the measuring plate, a connecting block welded to the outer wall of one side of the vernier plate, a connecting plate welded to the outer wall of one side of the vernier plate, a positioning cylinder welded to the outer wall of the connecting plate near the measuring plate, a groove on the outer wall of the measuring plate near the connecting plate, the positioning cylinder located inside the groove, a positioning spring installed inside the positioning cylinder, a guide post installed at one end of the positioning spring, and the guide post slidably connected inside the positioning cylinder.

[0004] In existing technologies, the rotation angle of the measuring ruler is limited to 90 degrees, which restricts the scope of application for construction surveying and is not conducive to multi-purpose use on construction sites. For example, when measuring the inclination dimensions of a beam with an inclination angle of less than 90 degrees, the existing measuring ruler cannot perform convenient measurements.

[0005] Therefore, a measuring device for building construction is needed. Utility Model Content

[0006] In view of the problems existing in the prior art, the present invention provides a measuring device for building construction, which aims to solve the aforementioned technical problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A measuring device for building construction includes a telescopic rod, a measuring ruler, a pull rod, and a rotating base. The top side of the telescopic rod is configured as the rotating base, and the measuring ruler is rotatably mounted on the rotating base so that the measuring ruler can be rotatably mounted on both sides of the telescopic rod. The back side of the measuring ruler away from the rotating base is configured as a rotating shaft one, and the side closer to the rotating base is configured as a rotating shaft two. The pull rod is rotatably mounted on the rotating shaft one. The back side of the telescopic rod is configured as a rotating shaft three, and a spring rod one is mounted on the rotating shaft three. A spring rod two is sleeved inside the spring rod one. The top of the spring rod two protrudes from the spring rod one and is rotatably mounted with the rotating shaft two. The overlapping part of the spring rod one and the spring rod two is sleeved and abuts against the spring one.

[0008] Preferably, the telescopic rod includes a fixed rod one and a fixed rod two. The top of the fixed rod one is set as a rotating base. The fixed rod two is slidably installed inside the fixed rod one. One side of the fixed rod one is set as a through hole. The side of the fixed rod two near the through hole is opened as a threaded hole one. A nut limiting component is installed in the threaded hole one. The nut limiting component abuts against the through hole.

[0009] Preferably, the measuring ruler has a groove in the middle, and a scale pointer is slidably installed inside the groove.

[0010] Preferably, the spring is in a compressed state and is positioned between the fixed rod 1 and the fixed rod 2.

[0011] In summary, this utility model provides a measuring device for building construction. This utility model patent uses a rotating base to rotatably mount the measuring ruler, allowing for a wide range of rotational settings beyond a 90-degree adjustment. It is suitable for measuring various tilt settings on crossbeams. It enables measurement under two opposing force conditions. During measurement: the tilt angle of the measuring ruler is adjusted by a pull rod, and the measuring ruler adheres to the bottom of the crossbeam. A spring provides a vertical force to the measuring ruler, ensuring it adheres to the bottom of the crossbeam. This achieves accurate measurement and convenient reading. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figures 1 to 3 As shown:

[0018] This utility model is a measuring device for building construction, including a telescopic rod 1, a measuring ruler 2, a pull rod 3, and a rotating base 4. The top side of the telescopic rod 1 is set as the rotating base 4, and the measuring ruler 2 is rotatably mounted on the rotating base 4 so that the measuring ruler 2 can be rotatably mounted on both sides of the telescopic rod 1. The side of the back of the measuring ruler 2 away from the rotating base 4 is set as a rotating shaft 5, and the side closer to the rotating base 4 is set as a rotating shaft 6. The pull rod 3 is rotatably mounted on the rotating shaft 5. The back side of the telescopic rod 1 is set as a rotating shaft 3 7, and a spring rod 11 is mounted on the rotating shaft 3 7. A spring rod 2 12 is sleeved inside the spring rod 11. The top of the spring rod 2 12 extends out of the spring rod 11 and is rotatably mounted with the rotating shaft 2 6. The overlapping part of the spring rod 11 and the spring rod 2 12 is sleeved and abutted by a spring 13.

[0019] To address the technical problem of existing measuring rulers being limited to a 90-degree rotation angle adjustment, causing inconvenience, this patent adopts a method with a wide range of angle adjustment, not limited to 90 degrees, enabling multi-purpose measurement. The specific structure is as follows: an adjustable-height telescopic rod 1 is used, with a rotating base 4 at its top. The rotating base 4 is located on one side of the back of the telescopic rod 1. The measuring ruler 2 is mounted by rotating the rotating base 4, allowing for a wide range of rotational settings, not limited to 90-degree adjustment, suitable for various inclined settings on crossbeams for measurement.

[0020] The measurement method is as follows: Pull the lever 3 manually to tilt the measuring ruler 2 so that it is in contact with the predicted surface of the crossbeam. A spring rod 11 and a spring rod 12 are installed on the side of the measuring ruler 2 closest to the rotating base 4. The spring rod 11 is internally fitted with the spring rod 12, and the spring rods 11 and 12 are elastically connected by a spring 13. This ensures that the spring rod 11 always pulls the measuring ruler 2 downwards, forcing it to return to its vertical position. Due to the pulling action of the lever 3, the measuring ruler 2 is measured under two opposite force conditions. During measurement: the lever 3 adjusts the tilt angle of the measuring ruler 2, causing it to fit against the bottom of the crossbeam. The spring 13 provides a vertical force to the measuring ruler 2, keeping it in contact with the bottom of the crossbeam. This achieves accurate measurement and convenient reading.

[0021] In at least one embodiment, in order to achieve height adjustment of the telescopic rod 1, the telescopic rod 1 includes a first fixed rod 14 and a second fixed rod 15. The top of the first fixed rod 14 is configured as a rotating base 4, and the second fixed rod 15 is slidably installed inside the first fixed rod 14. One side of the first fixed rod 14 is configured as a through hole 21, and the side of the second fixed rod 15 near the through hole 21 is provided with a threaded hole 16. A nut limiting member 17 is installed in the threaded hole 16, and the nut limiting member 17 is abutted against the through hole 21.

[0022] Specifically, the second fixing rod 15 is slidably installed inside the first fixing rod 14. One side of the first fixing rod 14 is provided with a through hole 21. The through hole 21 is a slotted through hole. The threaded hole 16 on the surface of the first fixing rod 14 is threadedly installed with the nut limiting part 17 to fix the first fixing rod 14 and the second fixing rod 15, thereby fixing the height of the telescopic rod 1 and measuring the crossbeams at different heights.

[0023] In at least one embodiment, in order to facilitate counting and reading of the measuring ruler 2, a groove 22 is provided in the middle of the measuring ruler 2, and a scale pointer 23 is slidably installed inside the groove 22.

[0024] In at least one embodiment, in order to ensure that the measuring ruler 2 is always rotated in the vertical direction, a spring 13 is placed in a compressed state between spring rod 11 and spring rod 12. Specifically, the spring rod 12 is always subjected to the elastic tension of spring 13, and the spring rod 12 is installed with the rotating measuring ruler 2 through the rotating shaft 6, so that the measuring ruler 2 is always rotated in the vertical direction, so that the measuring ruler 2 can be abutted against and attached to the bottom surface of the crossbeam, which can facilitate accurate reading and counting.

[0025] The embodiments described in this utility model are for illustrative purposes only and do not constitute a limitation on the scope of the claims. Other substantially equivalent substitutions that can be conceived by those skilled in the art are all within the protection scope of this utility model.
