Description

Technical Field

[0001] This invention relates to the field of measuring tools, specifically to a sports stadium grid frame correction and testing device. Background Technology

[0002] Stadiums are venues for sports activities, and they are divided into open-air stadiums and indoor stadiums. In open-air stadiums, the field is divided by a grid structure to prevent interference between different sports. However, the grid structure may tilt over time, and if it is not corrected, there is a risk of it collapsing. Therefore, staff need to regularly check the tilt of the grid structure using a calibration and testing device.

[0003] Patent document CN219810447U discloses a level, including a level body and an adjustable level seat. A bubble level is installed on the adjustable level seat. The adjustable level seat can rotate relative to the level body. The rotation of the adjustable level seat can drive the bubble level to rotate and adjust. It is a level with a simple structure that can rotate and adjust the level seat, allowing workers to accurately refer to the slope.

[0004] The spirit level in the aforementioned patent document is easy to use by rotating and adjusting, but there is still room for improvement in reducing usage costs. If the spirit level falls and causes inaccurate use, the entire spirit level needs to be replaced, which does not reduce usage costs.

[0005] In view of this, it is necessary to develop a sports stadium grid structure correction and testing device, which can reduce the horizontal operating cost by replacing the bubble column separately. Summary of the Invention

[0006] The purpose of this invention is to provide a sports stadium grid frame correction and testing device to solve the technical problem mentioned in the background art, which is that the existing level ruler falls off, causing the bubble level to be inaccurate, requiring the replacement of the entire level ruler, and thus failing to reduce the cost of use.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a stadium grid frame correction and testing device, comprising: a correction and testing ruler, wherein a detachable component is installed on the top side of the correction and testing ruler, the detachable component comprising a mounting groove, a first locking groove, a first magnetic ring and a vertical testing component, the mounting groove being opened on the top side of the correction and testing ruler, the first locking groove being symmetrically opened on the inner walls of both sides of the mounting groove, the first magnetic ring being fixedly embedded in the bottom inner wall of the mounting groove, and the vertical testing component being installed inside the mounting groove.

[0008] Preferably, the vertical detection component includes a mounting shell, a first limiting block, a second magnetic ring, a vertical bubble column, and a transparent circular plate. The first limiting block is symmetrically installed on both sides of the mounting shell and is slidably connected to a first locking groove. The second magnetic ring is fixedly embedded in the bottom of the mounting shell, the vertical bubble column is fixed inside the mounting shell, and the transparent circular plate is installed on the top of the mounting shell.

[0009] Preferably, the second magnetic ring corresponds to the first magnetic ring and they are magnetically attracted to each other.

[0010] Preferably, a rectangular groove is provided at the center of one side of the calibration detection ruler, and second locking grooves are symmetrically provided on the inner walls of both sides of the rectangular groove. A first magnetic column is fixedly embedded on the bottom inner wall of the rectangular groove.

[0011] Preferably, an installation frame is installed inside the rectangular groove, and second limiting blocks that are slidably connected to the second card slot are symmetrically installed on both sides of the installation frame. A horizontal bubble column is installed on the inner side of the installation frame, and a second magnetic column corresponding to the first magnetic column is installed at the bottom of the installation frame.

[0012] Preferably, the bottom of the calibration measuring ruler is equipped with a side magnetic plate, a measuring line is provided on one side edge of the top of the calibration measuring ruler, and a back magnetic plate is installed at the bottom of the calibration measuring ruler.

[0013] Preferably, the back of the calibration measuring ruler has a through hole that penetrates the center of the mounting groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] In this invention, the vertical detection component on the calibration measuring ruler is installed and used through a detachable component. If the vertical bubble column in the vertical detection component is damaged or becomes inaccurate and cannot be calibrated, the vertical detection component can be disassembled and replaced through the detachable component, without scrapping the entire calibration measuring ruler, thus reducing usage costs. The mounting shell in the vertical detection component is installed from the top of the mounting groove, and the first limiting block slides into the interior of the first locking groove from the top. After installation, the top of the transparent circular plate is flush with the top of the mounting groove without protrusion. The magnetic attraction between the first and second magnetic rings fixes the mounting shell inside for use. If disassembly is required, the operator can use a cylindrical rod or other tools that can be inserted through the through hole to push it out from the bottom of the mounting shell.

[0024] Example 1: Please refer to Figure 1 , Figure 3 and Figure 4 A device for correcting and testing the structure of a sports stadium's grid frame;

[0025] The system includes: a calibration measuring ruler 1, with a detachable assembly mounted on the top side of the calibration measuring ruler 1. The detachable assembly includes a mounting groove 5, a first locking groove 6, a first magnetic ring 7, and a vertical detection assembly. The mounting groove 5 is located on the top side of the calibration measuring ruler 1. The first locking groove 6 is symmetrically located on the inner walls of both sides of the mounting groove 5. The first magnetic ring 7 is fixedly embedded in the bottom inner wall of the mounting groove 5. The vertical detection assembly is installed inside the mounting groove 5 and includes a mounting shell 8, a first limiting block 9, a second magnetic ring 10, a vertical bubble column 11, and a transparent circular plate 12. The first limiting block 9 is symmetrically installed on both sides of the mounting shell 8 and is slidably connected to the first locking groove 6. The second magnetic ring 10 is fixedly embedded in the bottom of the mounting shell 8. The vertical bubble column 11 is fixed inside the mounting shell 8. The transparent circular plate 12 is installed on the top of the mounting shell 8. The second magnetic ring 10 corresponds to the first magnetic ring 7 and they are magnetically attracted to each other.

[0026] The calibration measuring ruler 1 is made of rectangular stainless steel, providing excellent drop and bending resistance to prevent damage from drops or pressure during use. The vertical detection component on the calibration measuring ruler 1 is installed and used via a detachable assembly. If the vertical bubble column 11 in the vertical detection component is damaged or becomes inaccurate and cannot be calibrated, the vertical detection component can be disassembled and replaced via the detachable assembly, eliminating the need to scrap the entire calibration measuring ruler 1 and reducing operating costs. The mounting shell 8 in the vertical detection component is made of stainless steel, with a circular hole on its inner wall that matches the vertical bubble column 11, allowing the vertical bubble column 11 to be confined inside the mounting shell 8. The vertical bubble column 11 is then fixed inside using adhesive. The first magnetic ring 7 and the second magnetic ring 1... 0 is a circular ring shape, which corresponds to the top and bottom after being installed, and the first limiting block 9 and the first locking groove 6 are fitted with a gap of 2mm. The transparent circular plate 12 is made of transparent plastic and is used to seal the top of the mounting shell 8 without affecting the staff's observation of the vertical bubble column 11. The mounting shell 8 is installed from the top of the mounting groove 5, and the first limiting block 9 slides into the interior of the first locking groove 6 from the top. After installation, the top of the transparent circular plate 12 is flush with the top of the mounting groove 5 without protrusion. The magnetic attraction between the first magnetic ring 7 and the second magnetic ring 10 fixes the mounting shell 8 inside for use. If disassembly is required, the staff can use a cylindrical rod or other tools that can be inserted through the through hole 13 to push it out from the bottom of the mounting shell 8.

[0027] Example 2: Please refer to Figure 1 and Figure 2 A device for correcting and testing the structure of a sports stadium's grid frame;

[0028] A rectangular groove 14 is provided at the center of one side of the calibration measuring ruler 1. Second locking grooves 16 are symmetrically provided on the inner walls of both sides of the rectangular groove 14. A first magnetic column 15 is fixedly embedded on the bottom inner wall of the rectangular groove 14. An installation frame 17 is installed inside the rectangular groove 14. Second limiting blocks 18 that are slidably connected to the second locking grooves 16 are symmetrically installed on both sides of the installation frame 17. A horizontal bubble column 19 is installed on the inner side of the installation frame 17. A second magnetic column 20 corresponding to the first magnetic column 15 is installed at the bottom of the installation frame 17.

[0029] The rectangular groove 14 and the mounting frame 17, the second locking groove 16 and the second limiting block 18 are fitted with a clearance. The clearance between them is 2mm during installation. The second limiting block 18 enters the interior of the second locking groove 16, thereby limiting the mounting frame 17 inside the rectangular groove 14. Then, the first magnetic post 15 and the second magnetic post 20 attract each other magnetically, limiting and fixing the mounting frame 17 inside the rectangular groove 14. The mounting frame 17 provides a position for the installation of the horizontal bubble column 19. When the horizontal bubble column 19 is inaccurate, the operator can remove and replace the horizontal bubble column 19 separately through the mounting frame 17.

[0030] Example 3: Please refer to Figure 1 and Figure 4 A device for correcting and testing the structure of a sports stadium's grid frame;

[0031] A side magnetic plate 2 is installed at the bottom of the calibration measuring ruler 1, a measuring line 3 is provided on one side edge of the top of the calibration measuring ruler 1, a back magnetic plate 4 is installed at the bottom of the calibration measuring ruler 1, and a through hole 13 is provided on the back of the calibration measuring ruler 1, and the through hole 13 passes through the center of the mounting groove 5.

[0032] The side magnetic plate 2 and the back magnetic plate 4 are fixedly embedded and are level with the surface of the calibration measuring ruler 1 without protrusion. This allows the calibration measuring ruler 1 to be used by adsorbing onto the grid frame without the need for the operator to hold it to maintain stability. The measuring line 3 is a scale line with a length of 40cm. The through hole 13 is a circular hole corresponding to the mounting groove 5, allowing the tool for disassembling and installing the circular shell 8 to be inserted and pushed out.

[0033] The working principle is as follows: First, when using the calibration and testing ruler 1, it is placed vertically and then horizontally on the sports stadium's net frame to check the levelness and verticality of the net frame. Workers can check whether the net frame is tilted by observing the horizontal bubble column 19 or the vertical bubble column 11. If the horizontal bubble column 19 or the vertical bubble column 11 is in the center position, it indicates that the frame is not tilted. If it is not in the center position, it indicates that it is tilted and needs to be corrected by workers. After correction, the test is carried out again to ensure that there is no tilt. At the same time, the horizontal bubble column 19 and the vertical bubble column 11 can be disassembled and replaced to avoid damage that would require the replacement of the entire calibration and testing ruler 1.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
