Technical Field

[0001] The utility model relates to the technical field of brightness meters, in particular to a light source alignment device for calibrating an imaging brightness meter. Background Art

[0002] A luminance meter is a measuring instrument for measuring light and color, and is one of the commonly used instruments and equipment in every chemical analysis laboratory.

[0003] When using a brightness meter for detection, it is usually necessary to align the brightness meter and the light source in a horizontal position so as to calibrate the light source.

[0004] When the brightness meter is used for detection, a supporting device is usually required to support the brightness meter, and the brightness meter and the light source need to be aligned with each other. During the alignment process, the brightness meter needs to be fixed with a supporting device, and the light source is set directly opposite the brightness meter, and a distance space is set between the brightness meter and the light source. The accuracy of the brightness meter is judged by recording the value of the brightness meter and comparing it with the light source parameters. When the brightness meter is aligned with the light source support, the supporting position is very likely to shake after adjustment, so it is easy to cause data deviation when calibrating the light source, and it is very inconvenient to adjust the brightness meter in various directions. To this end, we provide a light source alignment device for imaging brightness meter calibration to solve the above problems. Utility Model Content

Therefore, the support stability of the brightness meter is more important. For this purpose, this embodiment provides a light source alignment device for calibrating an imaging brightness meter. The device can not only facilitate the support and placement of the brightness meter, but also facilitate the adjustment of the height, angle and stability of the brightness meter according to needs.

[0027] refer to Figure 1 and Figure 2 The setting of the multi-section electric push rod 201 can achieve multiple extensions and retractions, thereby driving the transmission plate 202 to rise and fall during the extension and retraction process, and the mounting block 203 can better enable the first slide 204, the second slide 205 and the third slide 206 to perform expansion and contraction movements, and the first slide 204, the second slide 205 and the third slide 206 can be extended and retracted, and a self-adjusting method is adopted to avoid sliding after expansion.

[0028] The lower end of each third slide cylinder 206 is fixedly connected to a connecting rod 3, and the lower end of the connecting rod 3 is fixedly connected to a sphere 4. By setting the connecting rod 3, it is easy to cooperate with the sphere 4, which can better facilitate the support and placement of the overall device, and can facilitate the mutual cooperation of subsequent components to improve the stability of placement.

[0029] The outer surface of each sphere 4 is clamped with a placement plate 5, and the bottom surface of the placement plate 5 is provided with anti-slip grooves. By providing the placement plate 5, it is convenient to unfold and place the entire device through the placement plate 5, and the placement plate 5 can greatly improve the stability of the entire device and increase the friction between the device and the ground.

[0030] The upper surface of the fixed disk 1 is rotatably connected to a placement rod 6, and an imaging luminance meter 7 is installed on the upper end of the placement rod 6. By setting the placement rod 6, the imaging luminance meter 7 can be better placed and can be easily rotated slowly at the fixed disk 1, so that the imaging luminance meter 7 can adjust the light sources at different positions.

[0031] The outer surface of the fixed disk 1 is fixedly connected to a connecting plate 9, and a liquid level detector 10 is installed on the upper surface of the connecting plate 9. By providing the connecting plate 9, the installation and replacement of the liquid level detector 10 can be better facilitated, and the liquid level detector 10 can be used to observe whether the entire device is in a horizontal position, thereby avoiding the tilt of the entire device affecting the detection and calibration of the light source.

By providing the L-shaped connecting plates 11, the threaded rods 12 can be more conveniently installed and disassembled, and the placement rods 6 can be clamped and fixed more conveniently through the threaded rods 12, thereby preventing the placement rods 6 from being offset after being rotated and adjusted to affect their use.

[0036] The ends of the two threaded rods 12 that are close to each other are fixedly connected with a clamping plate 13, and the ends of the two threaded rods 12 that are away from each other are fixedly connected with a rotating plate 14. By setting the clamping plate 13, the clamping and fixing effect of the placement rod 6 can be further improved, and by setting the rotating plate 14, the threaded rod 12 can be easily rotated, thereby improving the practicability of the device.

[0037] Working principle: When calibrating and testing the light source, first place the imaging luminance meter 7 on the placement rod 6, and then rotate the two rotating plates 14, the rotating plate 14 drives the threaded rod 12 to rotate at the L-shaped connecting plate 11, so that the L-shaped connecting plate 11 drives the clamping plate 13 to clamp and fix the imaging luminance meter 7, so as to facilitate the rapid installation and removal of the imaging luminance meter 7. After the installation is completed, the imaging luminance meter 7 needs to be adjusted in angle and height. At this time, the multi-section electric push rod 201 can be started, and the output shaft of the multi-section electric push rod 201 drives the transmission plate 208 to move through the transmission disk 202, so that the transmission plate 208 passes through the connecting ring 207. The second slide 205, the first slide 204 and the third slide 206 are pushed to expand, and the first slide 204, the second slide 205 and the third slide 206 can be limited and fixed, so as to support the whole device, and the height of the whole device can be adjusted by the first slide 204, the second slide 205 and the third slide 206.
