Description

Technical Field

[0001] This utility model relates to the field of calibration brackets, and more particularly to a calibration bracket for measuring instruments. Background Technology

[0002] An existing patent (publication number: CN212567469U) proposes a calibration support for metrological verification, including a base, a storage unit, two clamping units, and two support columns. The two support columns are symmetrically arranged on the base. The storage unit includes a crossbeam, several collars, and several hooks. The clamping unit includes a clamping block, a connecting plate, a screw, and a pressure plate. The clamping block is slidably mounted on the support columns. However, in this device, "the measuring tools commonly used in metrological verification experiments are all strung with ropes and hung on the hooks; those that are inconvenient to strung with ropes are tied with ropes and hung on the hooks." The measuring tools are suspended at the crossbeam, occupying a large space and making it inconvenient for metrological verification experiments, thus presenting drawbacks. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a calibration bracket for measuring instruments that facilitates quick access to and inspection of metrological verification tools, saves verification experiment time, improves verification efficiency, and keeps the verification area clean.

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

[0005] A calibration support for a measuring instrument includes a calibration table, a support plate, a positioning rod, a tool disk, a drive rod, a base, and a transmission sleeve. The upper part of the calibration table is connected to the support plate, and a rubber pad is connected to the inner side of the support plate. The lower part of the support plate has a slider, and the calibration table has a slide rail. The slider is adapted to the slide rail and slides within the slide rail. The lower part of the calibration table has a fixed column, which is connected to the inside of a bearing. A turntable is connected to the outside of the bearing. The turntable has a tool disk with multiple partitions. The tool disk fits against the calibration table. The middle part of the calibration table has an upper placement groove, which is adapted to the driven sleeve and connected to the driven sleeve. The driven sleeve has a driven gear on its outside and a positioning rod connected to the inside of the driven sleeve by screws. The positioning rod passes through the calibration table, the slider, and the driven sleeve in sequence, and is connected to the slider by threads.

[0006] The transmission sleeve of this utility model is adapted to the upper placement groove and is connected to the upper placement groove. The transmission sleeve has a transmission gear on its outside, which meshes with the driven gear and is connected to the driven gear. The shaft passes through the fixed column and the transmission sleeve in sequence, and the transmission sleeve rotates on the shaft. The lower part of the fixed column is connected to the base, and the upper side of the base is attached to the tool disk. The middle part of the base has a lower placement groove, which is adapted to the drive sleeve and is connected to the drive sleeve. The drive sleeve has a drive gear on its outside, which meshes with the transmission gear and is connected to the transmission gear.

[0007] The base of this utility model has a fastening sleeve on the outside, the fastening sleeve fits into a knob, the knob has a drive rod, the drive rod is connected in sequence to the fastening sleeve, the base, and the drive sleeve, the drive sleeve has multiple drive protrusions, the drive rod has multiple drive grooves, the drive protrusions are adapted to the drive grooves, and the drive protrusions are connected to the drive grooves. Beneficial effects

[0008] This utility model's calibration stand uses two side support plates to quickly fix and support the measuring instruments and equipment to be calibrated, ensuring their stability during the calibration process, preventing movement, and guaranteeing measurement accuracy. By adding rubber pads to the inside of the support plates, the coefficient of friction is increased, enhancing the fixation effect on the measuring instruments and equipment. The rubber pads also absorb external vibrations or operational impacts, reducing the risk of direct collision between the instrument and the support plates and minimizing measurement deviations caused by vibration. Furthermore, the rubber pads act as a soft isolation layer, preventing scratches or deformation on the contact surfaces between the support plates and the instruments / equipment due to rigid friction, thus increasing the protection of the measuring instruments and equipment.

[0009] The drive rod, drive sleeve, transmission sleeve, driven sleeve, positioning rod, and slider of this utility model are linked together, so that by rotating the knob, the two side support plates can be driven to move synchronously inward or outward in a linear direction. This can meet the fixing requirements of measuring instruments and tools of different sizes, with high adaptability and quick and convenient control and adjustment operation, which can reduce the time for changing fixtures and improve the efficiency of measuring instrument calibration.

[0010] This utility model's calibration bench features an external tool tray. The tool tray, with its built-in partitions, categorizes and separates the metrological calibration tools, making the required tools readily visible, easy to access, and convenient for checking for missing tools. This saves calibration time and improves efficiency. Furthermore, by centrally storing tools outside the calibration bench, it prevents tools from scattering and occupying operating space, keeping the calibration area tidy and reducing the risk of instrument displacement due to tool collisions. The tool tray can also be rotated to quickly change the tool's position, further enhancing the convenience of calibration operations.

[0011] This utility model has high adaptability and convenient control and adjustment operation. It can meet the support and fixation requirements of measuring instruments and tools of different sizes, ensuring their stability during the verification process and guaranteeing measurement accuracy. At the same time, it facilitates quick access to and missing checks of measuring verification tools, saves verification experiment time, improves verification efficiency, keeps the verification area clean, reduces the risk of instrument displacement due to tool collisions, and has a reasonable structure.
