Technical Field

[0001] This utility model relates to the field of temperature and humidity meter technology, and in particular to a high-precision temperature and humidity measurement and verification device. Background Technology

[0002] A thermometer and hygrometer are used to measure the temperature and humidity of an environment to determine the environmental conditions for product production or storage. They are also used in people's daily lives. To ensure the accuracy of thermometers and hygrometers, a portion of samples is usually randomly selected for testing.

[0003] A search revealed that patent CN218297211U discloses a high-precision digital display thermometer and hygrometer calibration device. This device can use a camera to photograph data from multiple thermometers and hygrometers and upload it to a computer for processing. However, this device has the following shortcomings in use:

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example 1: Refer to Figures 1-4 A high-precision temperature and humidity measurement and verification device, comprising:

[0030] The structure and principle of the test box 1 are the same as those of the patent with publication number CN218297211U, so the structure and principle will not be described in detail. A door 2 is hinged to one side of the test box 1, and an observation window 3 is provided on one side of the door 2 to facilitate observation of the inside of the test box 1. A connecting plate 4 is fixed to one side of the door 2, and a camera 5 is fixed to the inner wall of one side of the connecting plate 4 to record image information during the test process.

[0031] Two guide plates 6 are fixedly installed on the bottom inner wall of the calibration box 1. A bracket 7 is slidably connected between the two guide plates 6. Two vertical rods 8 are fixedly installed on the bottom inner wall of the bracket 7. At least one movable plate 9 is slidably connected between the two vertical rods 8. A placement groove 10 is opened on one side of the movable plate 9. Multiple clamping plates 11 are slidably connected to the outer wall of the movable plate 9. A set screw 12 is threaded through one side of the clamping plate 11. One end of the set screw 12 abuts against the inner wall of one side of the placement groove 10. The position of the clamping plate 11 can be adjusted by rotating the set screw 12, thereby clamping and fixing the temperature and humidity measuring instrument.

[0032] Two adjustment mechanisms are respectively located on both sides of the support 7 to adjust the height of the movable plate 9. Each adjustment mechanism includes a threaded groove 17 and a strip groove 19. The threaded groove 17 is located on one side of the movable plate 9, and an adjusting bolt 18 is threaded into it. The strip groove 19 is located on the outer wall of one side of the support 7, and the adjusting bolt 18 passes through the strip groove 19 and abuts against the support 7. Multiple arc-shaped grooves 20 are provided on both sides of the strip groove 19, and the adjusting bolt 18 is located within these grooves. By rotating the adjusting bolt 18, the movable plate 9 can slide up and down on the vertical rod 8, thereby adjusting its height. When the adjusting bolt 18 is tightened, its head will be locked within the groove 20 to prevent loosening.

[0033] A limiting mechanism is installed on one side of the bracket 7 to limit its movement. The limiting mechanism includes an L-shaped fixing plate 14 and a limiting groove 16. The fixing plate 14 is fixed to the bottom inner wall of the calibration box 1, and the limiting groove 16 is formed in the bottom inner wall of the bracket 7. A limiting bolt 15 is threaded through the surface of the fixing plate 14, and the bottom end of the limiting bolt 15 is located within the limiting groove 16. By rotating the limiting bolt 15, its bottom end can be engaged into the limiting groove 16, thereby limiting the movement of the bracket 7.

[0034] Example 2: An improved high-precision temperature and humidity measurement and verification device based on Example 1;

[0035] In another aspect of this embodiment, a U-shaped connecting groove 22 is provided at the top of the bracket 7, and a connecting rod 21 is integrally formed at the top of the vertical rod 8. A connecting block 23 is sleeved between the connecting rod 21 and the connecting groove 22. The connecting block 23 can connect the vertical rod 8 and the bracket 7 more stably, increase the stability of the entire device, and also make it easier for people to remove and add or remove the moving plate 9.

[0036] In another aspect of this embodiment, two supplementary lights 24 are fixedly installed on the inner wall of one side of the connecting plate 4, and the two supplementary lights 24 are located on the upper and lower sides of the camera 5, respectively. The supplementary lights 24 can provide additional light sources, enabling the camera 5 to capture clearer images.

[0037] In another aspect of this embodiment, rubber pads 13 are adhered to both inner walls of the placement slot 10 and both sides of the clamping plate 11. The rubber pads 13 can increase the friction with the thermometer and hygrometer, preventing them from sliding or shaking during the calibration process.

[0038] However, as is well known to those skilled in the art, the working principle and wiring method of camera 5 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
