However, this testing device only has one support platform for placing the instrument during use, and it cannot classify and zon the testing of different parts of the instrument, which requires improvement. Summary of the Invention

[0003] To address the aforementioned shortcomings of existing technologies, this utility model provides a convenient, dual-layer detection structure for a metrology instrument calibration workbench that facilitates the classification and testing of different components during instrument testing.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A calibration workbench for measuring instruments includes a main testing platform, support legs, a U-shaped fixing plate, telescopic rods, side fixing plates, a universal joint, a rectangular secondary testing platform, a telescopic outer sleeve, a rotating gear plate, a circular testing plate, and an L-shaped mounting plate. The main testing platform is connected to the lower part of the support legs, with four support legs distributed at the four corners of the bottom of the main testing platform. The outer side of the main testing platform has an outer rectangular baffle, and the inner side of the main testing platform has an inner rectangular baffle. The main testing platform has an inner rectangular hole, and the rectangular secondary testing platform is adapted to the inner rectangular hole, inserted into the inner rectangular hole, and sliding within the inner rectangular hole. The lower part of the rectangular secondary testing platform is connected to the telescopic outer sleeve, and a set of telescopic outer sleeves are distributed at the bottom of the rectangular secondary testing platform. The upper part of the U-shaped fixing plate is connected to the main testing platform, and the lower part of the telescopic rods is connected to the U-shaped fixing plate. A set of telescopic rods are distributed on the U-shaped fixing plate.

The upper part of the universal tube is connected to the detection light.

[0007] The lower surface of the circular detection disk is in contact with the rectangular sub-detection platform. The upper rod of the rotating gear disk passes through the rectangular sub-detection platform and connects to the circular detection disk. The upper rod of the rotating gear disk rotates inside the rectangular sub-detection platform. The upper surface of the rotating gear disk is in contact with the lower surface of the rectangular sub-detection platform, and the rotating gear disk is located at the center of the rectangular sub-detection platform. Beneficial effects

[0008] 1. This utility model has four support legs installed below the main testing platform, forming a table body. Workers can sit and test the instrument. The instrument is placed on the main testing platform for testing. The outer rectangular baffle prevents instrument parts from falling off the outside of the main testing platform during metrological instrument verification, while the inner rectangular baffle prevents instrument parts from falling off through the inner rectangular hole. The testing lamp is installed and fixed to the side fixing plate through a universal tube. The universal tube allows the position and direction of the testing lamp to be changed by pulling it, allowing for testing of any part of the instrument. The rectangular secondary testing platform is placed at the inner rectangular hole. The rectangular secondary testing platform is designed to be movable, allowing specific parts to be placed on it for testing. The vertical movement of the rectangular secondary testing platform allows for close observation of the details of the tested parts. A U-shaped fixing plate is installed and fixed below the main testing platform. The telescopic plug and telescopic sleeve form a telescopic rod. This telescopic rod controls the vertical movement of the rectangular secondary testing platform, ensuring alignment between the inner rectangular hole and the rectangular secondary testing platform, and preventing misalignment during metrological instrument verification.

[0009] 2. In this utility model, the cylinder is mounted and fixed on a U-shaped fixing plate. When the cylinder works, it drives the rectangular secondary detection platform to move up and down. The upper rod of the rotating gear plate passes through the rectangular secondary detection platform and connects to the circular detection disk. While the rotating gear plate positions the center of the circular detection disk, it allows the circular detection disk to rotate on the rectangular secondary detection platform with the circular detection disk as its center. The component to be inspected is placed on the rectangular secondary detection platform. An L-shaped mounting plate is installed below the rectangular secondary detection platform, and the motor is mounted on the L-shaped mounting plate. The motor shaft is connected to the active gear plate, and the active gear plate meshes with the rotating gear plate. When the motor works, it drives the active gear plate to rotate, which in turn drives the rotating gear plate to rotate, thereby causing the circular detection disk to rotate above the rectangular secondary detection platform. This allows the component on the plate to be inspected 360 degrees. It is convenient to use. This double-layer detection structure makes it easier to classify and inspect different parts when testing the instrument. Attached Figure Description

The main testing platform 01 is connected to the support legs 02 at its lower part. The four support legs 02 are distributed at the four corners of the bottom of the main testing platform 01, forming a table body with the main testing platform 01. Workers can sit and perform testing on the instruments placed on the main testing platform 01. The main testing platform 01 has an outer rectangular baffle 03 on its outer side to prevent instrument parts from falling off during calibration. The main testing platform 01 also has an inner rectangular baffle 04 on its inner side to prevent the measuring instruments from falling off. To prevent instrument parts from falling out of the inner rectangular hole 05 during calibration, the main testing platform 01 has an inner rectangular hole 05, and the rectangular secondary testing platform 11 is adapted to the inner rectangular hole 05. The rectangular secondary testing platform 11 is inserted into the inner rectangular hole 05 and slides within the inner rectangular hole 05. The rectangular secondary testing platform 11 is positioned at the inner rectangular hole 05. The rectangular secondary testing platform 11 is designed as a movable structure, allowing specific parts to be placed on it for testing during use. The rectangular secondary testing platform 11 can be moved up and down to observe the details of the tested parts at close range. The lower part of the rectangular secondary testing platform 11 is connected to a telescopic sleeve 12, and a set of telescopic sleeves 12 are distributed at the bottom of the rectangular secondary testing platform 11. The upper part of the U-shaped fixing plate 06 is connected to the main testing platform 01, and the lower part of the telescopic insertion rod 07 is connected to the U-shaped fixing plate 06. A set of telescopic insertion rods 07 are distributed on the U-shaped fixing plate 06.

[0018] Example 2:

[0019] The lower part of the telescopic jacket 12 of this utility model is adapted to the telescopic insert rod 07. The lower part of the telescopic jacket 12 is inserted into the telescopic insert rod 07, and the telescopic jacket 12 slides inside the telescopic insert rod 07. The U-shaped fixing plate 06 is installed and fixed below the main testing table 01. The telescopic insert rod 07 and the telescopic jacket 12 form a telescopic rod. This telescopic rod controls the vertical movement of the rectangular secondary testing table 11 and limits its position to ensure the alignment of the inner rectangular hole 05 with the rectangular secondary testing table 11, preventing misalignment during the calibration of measuring instruments. The lower part of the rectangular secondary testing table 11 has a circular connecting block 13 and a cylinder 1. The lower part of the cylinder 18 is connected to the U-shaped fixing plate 06. The piston rod of the cylinder 18 is connected to the circular connecting block 13. The cylinder 18 is installed and fixed on the U-shaped fixing plate 06. When the cylinder 18 is working, it drives the rectangular secondary detection stage 11 to move up and down. The outer rectangular baffle 03 is connected to the side fixing plate 08. The lower part of the universal tube 09 is connected to the side fixing plate 08. The upper part of the universal tube 09 is connected to the detection lamp 10. The detection lamp 10 is installed and fixed on the side fixing plate 08 through the universal tube 09. The universal tube 09 makes it easy to change the position and direction of the detection lamp 10 as it is pulled, so that the instrument can be ignited and detected at any point.

[0020] Example 3:

[0021] The lower surface of the circular detection disk 16 of this invention is in contact with the rectangular secondary detection platform 11. The upper rod of the rotating gear disk 14 passes through the rectangular secondary detection platform 11 and connects to the circular detection disk 16. While the rotating gear disk 14 positions the center of the circular detection disk 16, it allows the circular detection disk 16 to rotate on the rectangular secondary detection platform 11 with the circular detection disk 16 as the center. The component to be inspected is placed on the rectangular secondary detection platform 11. The upper rod of the rotating gear disk 14 rotates inside the rectangular secondary detection platform 11. The upper surface of the rotating gear disk 14 is in contact with the lower surface of the rectangular secondary detection platform 11, and the rotating gear disk 14 is located at the center of the rectangular secondary detection platform 11.

The measuring instrument is placed on a circular detection plate 16. The L-shaped mounting plate 17 is installed below the rectangular secondary detection platform 11. The motor 19 is installed on the L-shaped mounting plate 17. The motor 19's rotating shaft is connected to the drive gear 20, which meshes with the rotating gear 14. When the motor 19 is working, it drives the drive gear 20 to rotate, which in turn drives the rotating gear 14 to rotate. This causes the circular detection plate 16 to rotate above the rectangular secondary detection platform 11, allowing the components on it to be further inspected from 360 degrees. This design is convenient to use.
