Abstract
Description
Technical Field
[0001] This utility model relates to the field of verticality calibration technology, and specifically to a wall verticality calibration device. Background Technology
[0002] Wall verticality calibration is a key step in ensuring the safety of building structures, guaranteeing the quality of decoration, and improving the usability of space. As the core load-bearing or enclosure component of a building, if the verticality deviation of the wall is too large, it will easily lead to uneven stress. Long-term use may cause problems such as wall cracking and tilting, and in severe cases, it may even affect the overall stability of the building. Calibration can avoid such safety hazards from the source. The existing wall verticality calibration device does not have a self-balancing function. It needs to be manually adjusted to keep it level during use. Otherwise, the device will tilt due to uneven ground, which will affect the accuracy of verticality calibration. Therefore, it needs to be improved. Therefore, it is necessary to invent a wall verticality calibration device. Utility Model Content
[0003] Therefore, this utility model provides a wall verticality calibration device to solve the problems in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a wall verticality calibration device, comprising a frame, a base plate on the top of the frame, a base block fixedly connected to the top of the base plate, and a rotating shaft fixedly embedded on the base block, and two calibration components arranged in a centrally symmetrical manner on the base plate. A sphere is movably embedded in the top of the frame. A connecting block is fixedly connected between the sphere and the base plate. A vertical rod is fixedly connected to the bottom of the sphere. A plumb bob is fixedly connected to the bottom end of the vertical rod. A limiting component is provided on the rear side of the sphere.
[0005] Preferably, the limiting component is a fastening bolt, which is embedded in the top of the frame and located on the rear side of the ball, and the fastening bolt is threadedly connected to the frame.
[0006] Preferably, one end of the fastening bolt is configured as an arc shape and fits tightly against the surface of the sphere.
[0007] Preferably, the calibration component includes a rotating block, a sleeve, a moving rod, a calibration rod, and two triangular blocks.
[0008] Preferably, the rotating block is sleeved outside the rotating shaft and connected to it through a damping bearing, the sleeve is fixedly connected to one side of the rotating block, the moving rod is slidably disposed in the sleeve, and the calibration rod is fixedly connected to one side of the moving rod, and the two triangular blocks are respectively fixedly connected to the top and bottom sides of the calibration rod.
[0009] Preferably, a protrusion is fixedly embedded at the top of the sleeve, and a second fastening bolt is embedded on the protrusion. The second fastening bolt is connected to the protrusion by a thread, and the bottom end of the second fastening bolt is in contact with the top of the moving rod.
[0010] Preferably, a pointer is fixedly connected to the other side of the rotating block, and an angle ruler is fixedly connected to the front side of the base block.
[0011] Preferably, the frame is fixedly connected to four support legs at the bottom corners.
[0012] The beneficial effects of this utility model are: The device is equipped with components such as a ball, a vertical rod, and a plumb bob on a frame. Its automatic leveling principle is based on gravity. When the device is placed on an uneven surface, the plumb bob remains vertically downward due to gravity, causing the vertical rod to shift. The shift of the vertical rod causes the ball to roll on the top of the frame. The rolling of the ball causes the connecting block, base plate, base block, rotating shaft, and two calibration components to move and reach a horizontal state. In this way, the device has a self-balancing function. When using it, you only need to place the device on the ground to achieve a horizontal state, without the need for manual adjustment, which can reduce the labor intensity of manual labor.

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0018] See attached document Figure 1 -Appendix Figure 6 The present invention provides a wall verticality calibration device, including a frame 1, a base plate 2 on the top of the frame 1, a base block 3 fixedly connected to the top of the base plate 2, and a rotating shaft 4 fixedly embedded on the base block 3. The base plate 2 is provided with two calibration components that are centrally symmetrical. A sphere 5 is movably embedded in the top of the frame 1. A connecting block 6 is fixedly connected between the sphere 5 and the base plate 2. A vertical rod 7 is fixedly connected to the bottom of the sphere 5. A plumb bob 8 is fixedly connected to the bottom end of the vertical rod 7. A limiting component is provided on the rear side of the sphere 5. Support legs 19 are fixedly connected to the four corners of the bottom of the frame 1. When calibrating the verticality of a wall, simply place this device on the ground next to the wall. This will bring one of the calibration components close to the wall. Since the frame 1 is equipped with components such as a ball 5, a vertical rod 7, and a plumb bob 8, it can automatically achieve horizontal adjustment. The principle of horizontal adjustment is based on gravity. When the device is placed on an uneven ground, the plumb bob 8 will always remain vertical and downward under the action of gravity, causing the vertical rod 7 to shift. The shift of the vertical rod 7 will cause the ball 5 to roll on the top of the frame 1. The rolling of the ball 5 will drive the connecting block 6, the base plate 2, the base block 3, the rotating shaft 4, and the two calibration components to move and achieve a horizontal state. In this way, the device has a self-balancing function. When using it, you only need to place the device on the ground to achieve horizontality without manual adjustment, which can reduce the labor intensity of manual labor. The base plate 2 is square, the base block 3 is located at the top center of the base plate 2, the pivot 4 is embedded in the base block 3 and extends outwards at the same length, and the two calibration components are symmetrical. This ensures that the center of gravity of the connecting block 6, base plate 2, base block 3, pivot 4 and the two calibration components are coaxial with the center of gravity of the connecting block 6, sphere 5, vertical rod 7 and plumb bob 8, thus ensuring the accuracy of the self-balancing result. When the connecting block 6, base plate 2, base block 3, rotating shaft 4 and two calibration components are in a horizontal state, the position of the ball 5 can be restricted by the limiting components, thereby preventing the above components from shaking when the device is touched manually. Specifically, the limiting component is fastening bolt 9, which is embedded in the top of the frame 1 and located on the rear side of the ball 5. Fastening bolt 9 is connected to the frame 1 by threads, and the front end of fastening bolt 9 is set in an arc shape and fits tightly against the surface of the ball 5. When in use, tighten the fastening bolt 9 so that the front end of the fastening bolt 9 fits tightly against the rear side of the ball 5. This will compress the ball 5 and prevent it from moving randomly. This will allow the connecting block 6, base plate 2, base block 3, rotating shaft 4 and two calibration components to wobble when level. Subsequently, the verticality of the wall can be calibrated manually using the calibration components; Specifically, the calibration components include a rotating block 10, a sleeve 11, a moving rod 12, a calibration rod 13, and two triangular blocks 14. The rotating block 10 is sleeved on the outside of the rotating shaft 4 and connected to it through a damping bearing. The sleeve 11 is fixedly connected to one side of the rotating block 10. The moving rod 12 is slidably disposed in the sleeve 11, and the calibration rod 13 is fixedly connected to one side of the moving rod 12. The two triangular blocks 14 are respectively fixedly connected to the top and bottom sides of the calibration rod 13. A protrusion 15 is fixedly embedded in the top of the sleeve 11, and a fastening bolt 16 is embedded in the protrusion 15. The fastening bolt 16 is connected to the protrusion 15 by a thread. The bottom end of the fastening bolt 16 contacts the top of the moving rod 12. A pointer 17 is fixedly connected to the other side of the rotating block 10, and an angle ruler 18 is fixedly connected to the front side of the base block 3. During calibration, the second fastening bolt 16 is manually tightened until its bottom end is no longer in contact with the moving rod 12. Then, the calibration rod 13 and the moving rod 12 are pulled towards the wall until the two triangular blocks 14 on the calibration rod 13 contact the wall. Once the lower triangular block 14 contacts the wall first, the calibration rod 13, the moving rod 12, the sleeve 11, and the rotating block 10 can be rotated around the first rotating shaft 4, causing the calibration rod 13 to tilt. Then, the upper triangular block 14 will contact the wall. The rotation of the rotating block 10 can also drive the pointer 17 to rotate. After both triangular blocks 14 are in contact with the wall, observe which degree the pointer 17 points to on the angle ruler 18 to determine if the verticality is qualified. In addition, the distance between the two triangular blocks 14 and the moving rod 12 is the same, so that the moving rod 12 does not rotate eccentrically when it rotates around the first rotating shaft 4. The calibration steps for the upper triangular block 14 to first contact the wall are the same as those described above, so they will not be elaborated on here. After the device is used, the parts in the calibration components will be returned to their original positions to facilitate the self-balancing work before the next verticality calibration. The parts in the other two calibration components are made of lightweight materials, such as aluminum, to avoid the device from being top-heavy. The above are merely preferred embodiments of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model shall fall within the scope of protection claimed by this utility model.
