Description

Technical Field

[0001] The utility model relates to a verticality measuring device. Background Art

[0002] In construction, accurate measurement of verticality is a crucial step in ensuring the stability and safety of building structures. Especially during the construction of walls, formwork, and exterior walls, verticality measurement is often used to determine whether building components are perpendicular to the ground or other reference surfaces, which is directly related to the quality of the project. Traditional verticality measurement methods typically rely on the use of plumb bobs and wire ropes, requiring construction workers to climb to heights or use constructed formwork supports to perform measurements. This method is not only cumbersome and time-consuming, but also poses significant safety risks, as construction workers need to work at height and remain in dangerous positions for extended periods. Furthermore, the measurement accuracy of traditional methods is limited by the experience and operational stability of construction workers, and the operation process often requires the cooperation of multiple people, resulting in high labor costs for measurement.

[0003] Currently, traditional measurement methods rely on manually fixed plumb lines or wire ropes, and verticality is determined by measuring the distance between the plumb line and the wall or formwork. However, plumb line methods are significantly affected by climatic conditions, especially in strong winds, where the wire rope can easily deflect, resulting in inaccurate measurement results. Furthermore, the physical contact caused by plumb line methods with the wall or formwork surface can easily cause surface damage, increasing subsequent repair and maintenance costs. Utility Model Content

[0004] The purpose of the utility model is to provide a verticality measuring instrument to solve the problems of traditional verticality measurement such as potential safety hazards in high-altitude operations, significant interference from environmental factors and low efficiency.

[0005] The utility model is implemented as follows: a verticality measuring instrument, whose structure includes a horizontal rod, a connecting piece connected to one end of the horizontal rod, a first connecting rod connected to the other end of the horizontal rod, a second connecting rod hinged at the lower end of the first connecting rod, a laser emitter connected to the lower end of the second connecting rod, and a spirit level arranged on the side wall of the laser emitter; the horizontal rod is perpendicular to the first connecting rod; the first connecting rod and the second connecting rod are connected by a damping ball joint shaft.

[0006] Furthermore, a ratchet is used as a connecting device between the horizontal rod and the first connecting rod.

[0007] Furthermore, an adjustable stop hinge is used as a connecting device between the horizontal rod and the first connecting rod.

[0008] Furthermore, the laser emitter is threadedly connected to the second connecting rod.

[0009] Furthermore, an internally threaded tube is provided at the upper end of the laser emitter, and an externally threaded section cooperating therewith is provided at the lower portion of the second connecting rod.

[0010] Furthermore, the horizontal rod is a telescopic rod.

[0011] Furthermore, the connecting piece is a suction cup.

[0012] Furthermore, the connecting member is a strong magnetic block.

[0013] The laser emitter of the utility model is rotatable to emit laser vertically upward, avoiding the need for construction workers to climb up and down the formwork support to fix the plumb line, thereby significantly reducing the hidden danger of falling from height and ensuring the safety of construction workers.

[0014] The utility model is easy to operate and only requires one person to operate without the need for cooperating personnel, thus saving manpower and improving work efficiency.

[0015] The utility model utilizes the infinite extension characteristic of the laser line and only requires one person to operate without the need for cooperating personnel, thus greatly saving human resources and improving work efficiency.

[0016] The utility model has strong stability, and the damping ball hinge shaft provides a good damping effect, so that the laser emitter can remain stable during the angle adjustment process and will not shift its position due to slight external force or vibration, thereby improving the stability and reliability of the equipment.

[0017] The utility model is adsorbed on the wall or the template by a strong magnetic block or a suction cup, which will not cause damage to the surface to be measured, avoids the waste of manpower and material resources for later repair, improves efficiency and reduces costs.

[0018] This new model has strong adaptability and can be used not only in sunny weather but also in inclement weather conditions, ensuring all-weather measurement capabilities. At the same time, the measuring instrument can not only measure the verticality of templates, but also the verticality of exterior walls and plastered surfaces, achieving multi-purpose functions and a wide range of applications.

[0019] The horizontal rod of the utility model adopts a telescopic design, and the length can be adjusted as needed, so that the laser ray emitted by the laser emitter can pass through obstacles and illuminate the point to be measured on the surface to be measured, thereby enhancing the flexibility of measurement.

[0025] like Figures 1-4 As shown, the upper portion of the present invention comprises a horizontal rod 1, with a connector provided at one end of the horizontal rod 1 and a first connecting rod 2 connected to the other end of the horizontal rod. The first connecting rod 2 is perpendicular to the horizontal rod 1. A second connecting rod 3 is hingedly connected to the lower end of the connecting rod 2, and a laser emitter 4 is connected to the lower end of the second connecting rod 3. A level 5 is provided on the side wall of the laser emitter 4. During use, the present invention is fixed to a surface to be measured 8 of a wall or template via the connector. After adjusting the angle of the laser emitter 4 to make it vertical, the distance between the laser light emitted by the laser emitter 4 and the surface to be measured 8 is measured with a ruler. The verticality of the surface to be measured 8 is calculated based on the distances at different positions.

[0026] One end of the horizontal rod 1 is fixedly connected to the connecting piece. The horizontal rod 1 is a telescopic rod. By adjusting the length of the telescopic rod, the distance between the laser emitter 4 and the surface to be measured 8 can be adjusted. When there are obstacles between the point to be measured and the laser emitter, measuring tools with fixed lengths are often difficult to perform. The utility model adjusts the length of the horizontal rod 1 so that the laser rays emitted by the laser emitter 4 can pass through these obstacles and illuminate the point to be measured on the surface to be measured 8.

[0027] The connecting member is a strong magnet (not shown) or a suction cup 7. The strong magnet can be attached to the wall by adhering to the rebar within, or directly to the formwork. The suction cup 7 is pressed to displace air from the inside, creating a negative pressure between the suction cup 7 and the side surface 8 of the belt, forcing the suction cup 7 to fit tightly against the surface to be measured 8, ensuring a secure connection between the horizontal rod 1. The suction cup 7 is suitable for various smooth wall surfaces, such as tiled walls.

[0028] A ratchet 6 is used as a connecting device between the horizontal rod 1 and the first connecting rod 2. Both the horizontal rod 1 and the first connecting rod 2 are fixedly connected to the ratchet 6. The ratchet 6 enables the first connecting rod 2 to rotate 360 ​​degrees vertically around the horizontal rod 1. By adjusting the rocker 61 on the ratchet 6, the first connecting rod 2 can be restricted from rotating downward, thereby adjusting the angle of the laser emitter 4.

[0029] An adjustable stop hinge may also be used as a connection device (not shown) between the horizontal rod 1 and the first connecting rod 2 . The adjustable stop hinge allows the user to adjust the angle and position of the laser emitter 4 according to actual needs.

[0030] The first connecting rod 2 and the second connecting rod 3 are connected by a damping ball joint shaft 9. The damping structure of the damping ball joint shaft 9 is generally composed of a damping material or a damping device. The damping material can be rubber, silicone, oil, etc., which generates a damping force through its viscosity or fluidity. The damping device can be a mechanical structure such as a spring, gasket, or friction plate, which achieves a damping effect through mechanical friction or elastic deformation. The damping structure provides resistance during the rotation of the ball joint, making the rotation process smoother and slower, and can also maintain the position of the components after the rotation stops. The good damping effect ensures that the components remain in the specified position after the rotation stops, and will not shift position due to slight external forces or vibrations, thereby improving the stability and reliability of the device. The damping ball joint shaft 9 can adjust the laser emitter 4 to a vertical position, and its damping ensures that it remains parallel to the surface to be measured 8. During the rotation of the laser emitter 4 by the ratchet 6 or the adjustable stop hinge, the laser emitter 4 remains parallel to the surface to be measured 8.

[0031] like Figure 2 As shown, the laser emitter 4 is threadedly connected to the second connecting rod 3. An internally threaded tube 41 is provided at the upper end of the laser emitter 4, and an externally threaded section 31 is provided at the lower portion of the second connecting rod 3 to mate with it. This threaded connection is not only secure and reliable, but also facilitates disassembly and reassembly, greatly facilitating equipment maintenance and upgrades. There are two laser emitters 4, one as a backup. When one laser emitter 4 runs out of power, it is replaced with the backup. This seamless replacement process not only improves work efficiency but also ensures the smooth completion of tasks without being affected by power issues.

[0032] The level 5 is a bubble level with a scale. The level 5 is connected to the laser emitter 4 at a right angle. By adjusting the damping ball hinge shaft 9, the bubble of the bubble level is located in the center. At this time, the laser emitter 4 is in a vertical state, parallel to the surface to be measured 8, and the laser emitted by the laser emitter 4 extends downward.

[0033] When using the present invention, the laser emitter 4 is first mounted on the lower end of the second connecting rod 3. Next, the present invention is fixed to the surface to be measured 8 by adsorption via a connector. The position of the damping ball hinge shaft 9 is then adjusted until the bubble of the level 5 on the laser emitter 4 is centered. At this point, the laser emitter 4 is in a vertical position. At least two points are selected on the laser path projected by the laser emitter 4, and the distances from these points to the surface to be measured are measured using a ruler. The verticality of the wall or template is then calculated. The tilt angle of the laser emitter 4 is adjusted using a ratchet 6 or an adjustable stop hinge to detect the verticality or horizontality of the surface to be measured 8 in all directions.
