DETAILED DESCRIPTION

[0036] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0037] like Figure 1-Figure 7 As shown:

[0038] A thermometer and hygrometer calibration device provided in an embodiment of the present application includes a calibration box 1, wherein a rotatable mounting frame 7 is installed inside the calibration box 1, and a plurality of vertical rods 8 in an annular shape and distributed vertically are fixed on the mounting frame 7.

[0039] A plurality of mounting seats 14 distributed up and down and used for mounting a plurality of thermometers and hygrometers are mounted on each vertical rod 8 , and the mounting seats 14 are perpendicular to the vertical rod 8 .

[0040] The mounting seat 14 is connected to the vertical rod 8 by rotation and up and down sliding, so that the mounting seat 14 can rotate on the vertical rod 8 or move along the height direction of the vertical rod 8, and the mounting seat 14 can be locked after rotation or sliding.

[0041] In this embodiment, the calibration box 1 includes an equipment warehouse 2 and a calibration warehouse 3. The calibration warehouse 3 is installed above the equipment warehouse 2. A temperature and humidity control system for controlling the temperature and humidity in the calibration warehouse 3 is installed inside the equipment warehouse 2 (the temperature and humidity control system is a prior art and will not be described in detail), and the temperature and humidity control system is connected to the calibration warehouse 3 to provide hot air of different temperatures and humid air of different temperatures to the calibration warehouse 3. A standard thermometer and hygrometer is provided inside the calibration warehouse 3. A control panel 4 for receiving detection signals from the standard thermometer and hygrometer and displaying the temperature and humidity in the calibration warehouse 3 is installed on the outer wall of the equipment warehouse 2, and the control panel 4 can complete the operation and control of the temperature and humidity control system to adjust the temperature and humidity in the calibration warehouse 3. A sealed door 5 is installed at the front end of the calibration warehouse 3, and a glass observation window 6 is provided on the sealed door 5 and the calibration warehouse 3.

[0042] Furthermore, the mounting bracket 7 can be rotatably mounted inside the calibration chamber 3 .

[0043] When in use, first open the sealing door 5, rotate one of the vertical rods 8 to the front end of the calibration chamber 3, move the mounting seat 14 at the bottom of the vertical rod 8 to a suitable position at the bottom, and then install a thermometer and hygrometer of the same or similar size on the mounting seat 14, then move the mounting seat 14 above the mounting seat 14 to a suitable height position, so that the gap between the mounting seat 14 located above and the thermometer and hygrometer below it is as small as possible, and then install a thermometer and hygrometer of the same or similar size on the mounting seat 14 located above, so as to install the thermometer and hygrometer on each mounting seat 14 on the vertical rod 8 from bottom to top. At the same time, the number of mounting seats 14 for installing the thermometer and hygrometer on each vertical rod 8 can be selected according to the size of the thermometer and hygrometer, so that the number of mounting seats 14 can be selected as much as possible in the limited space of the calibration chamber 3 according to the size of the thermometer and hygrometer, so as to increase the number of thermometers and hygrometers to be installed. Specifically, it is only necessary to rotate and move the mounting seats 14 that are not needed to the side of other mounting seats 14.

[0044] After all the mounting seats 14 on each vertical rod 8 are installed with thermometers and hygrometers, rotate the mounting frame 7, rotate the next vertical rod 8 to the front end of the calibration chamber 3, and then install the thermometer and hygrometer according to the above installation method, thereby completing the installation of all thermometers and hygrometers in a single batch.

[0045] The thermometer and hygrometer calibration device provided in this embodiment is equipped with a rotatable mounting frame 7 inside the calibration box 1, and a plurality of vertical rods 8 in a ring shape and vertically distributed are fixed on the mounting frame 7, and a plurality of mounting seats 14 distributed up and down and used for mounting a plurality of thermometers and hygrometers are installed on each vertical rod 8, and the mounting seats 14 are perpendicular to the vertical rods 8, and the mounting seats 14 are connected to the vertical rods 8 by rotation and up and down sliding, and the mounting seats 14 can be locked after rotation or sliding, so that when in use, the height position of the mounting seat 14 can be flexibly adjusted according to the size of the thermometer and hygrometer to reduce the gap between the upper and lower adjacent thermometers and hygrometers, thereby improving the space utilization rate of the calibration box 1, and according to the size of the thermometer and hygrometer, as many mounting seats 14 as possible can be selected in the limited space of the calibration box 1 to increase the number of thermometers installed, thereby increasing the number of thermometers calibrated at a single time in a limited space, thereby improving the calibration efficiency of the thermometer and hygrometer.

[0046] In some embodiments of the present application, the mounting base 14 includes a bottom plate 15 , and a first vertical plate 16 and a second vertical plate 17 which are perpendicular to and parallel to each other are welded and fixed to the upper end of the bottom plate 15 .

[0047] A plurality of clamping members 18 are mounted on the first vertical plate 16 and are movable along the length direction thereof.

[0048] The thermometer and hygrometer can be clamped between the clamping member 18 and the second vertical plate 17 .

[0049] In this embodiment, by clamping the thermohygrometer between the clamping member 18 and the second vertical plate 17, the thermohygrometer can be installed vertically in the calibration chamber 3, thereby reducing the error of the value read by the staff when calibrating the pointer-type thermohygrometer, and the thermohygrometer can be fixed between the first vertical plate 16 and the second vertical plate 17 by clamping, thereby preventing the thermohygrometer from rolling or shaking after installation, so that the mounting seat 14 can stably install thermohygrometers of different shapes, and the clamping method can enable the mounting seat 14 to install thermohygrometers with relatively or similar sizes but different thicknesses. By providing a movable clamping member 18, the mounting seat 14 can install thermohygrometers of different sizes for different calibration batches.

[0050] In some embodiments of the present application, the clamping member 18 includes a movable member 19 and a movable rod 22. The movable rod 22 passes through the movable member 19 and is slidably connected to the movable member 19. One end of the movable rod 22 is connected to the movable member 19 through a spring 24, and the spring 24 is sleeved on the movable rod 22 to reduce occupied space.

[0051] The first vertical plate 16 is provided with sliding grooves 25 distributed along the length direction thereof, the moving member 19 is slidably connected to the sliding grooves 25 , and one end of the movable rod 22 extends between the first vertical plate 16 and the second vertical plate 17 .

[0052] When in use, the staff can manually push the movable member 19 to complete the movement of the clamping member 18. When installing the thermometer and hygrometer, it is only necessary to pull the movable rod 22, at which time the spring 24 is compressed, and the distance between the movable rod 22 and the second vertical plate 17 is greater than the thickness of the thermometer and hygrometer, and then the thermometer and hygrometer are placed between the two, and then the movable rod 22 is released, and at this time the thermometer and hygrometer are tightly pressed between the movable rod 22 and the second vertical plate 17.

[0053] In some embodiments of the present application, the moving member 19 includes a rectangular block 20 , on which two symmetrically distributed rubber plates 21 are fixed.

[0054] The movable rod 22 penetrates the rectangular block 20 and is slidably connected to the rectangular block 20. Specifically,

[0055] The rectangular block 20 is provided with a through hole 23 , and the movable rod 22 passes through the through hole 23 and contacts with the hole wall of the through hole 23 .

[0056] The rectangular block 20 passes through the slide groove 25 and contacts the slide groove 25. The first vertical plate 16 is located between the two rubber plates 21, and the two rubber plates 21 press the first vertical plate 16 at the same time. After the rubber plates 21 press the first vertical plate 16, it can prevent the rectangular block 20 from moving at will without external force, that is, prevent the clamping member 18 from moving at will.

[0057] When in use, the rectangular block 20 only needs to be pushed, and the rectangular block 20 can move along the slide groove 25 .

[0058] In order to improve the stability of clamping the thermometer and hygrometer between the movable rod 22 and the second vertical plate 17. In some embodiments of the present application, a first anti-skid rubber pad 26 for pressing the thermometer and hygrometer is fixed to one end of the movable rod 22.

[0059] In order to further improve the stability of clamping the thermometer and hygrometer between the movable rod 22 and the second vertical plate 17. In some embodiments of the present application, a second anti-skid rubber pad 27 adapted to the end of the second vertical plate 17 in contact with the thermometer and hygrometer is fixed.

[0060] In some embodiments of the present application, a mounting block 9 is fixed in the middle position of the second vertical plate 17, and a circular hole 10 is formed in the mounting block 9, and a threaded hole 11 is formed on the mounting block 9 and is connected to and perpendicular to the circular hole 10, and a bolt 12 is connected to the threaded hole 11 and meshes with it.

[0061] The vertical rod 8 is a cylindrical structure, and the vertical rod 8 passes through the circular hole 10 and contacts the circular hole 10 .

[0062] When in use, it is only necessary to rotate the bolt 12 until the bolt 12 is no longer in contact with the vertical rod 8, and then the second vertical plate 17 can be rotated or moved on the vertical rod 8, that is, the mounting seat 14 can be moved. After the mounting seat 14 is rotated or moved, the bolt 12 is rotated again so that the bolt 12 is pressed tightly against the vertical rod 8 to achieve the locking work of the mounting seat 14, thereby having the effect of convenient operation.

[0063] In some embodiments of the present application, the mounting frame 7 is located at the inner upper part of the verification box 1, and the upper end of the mounting frame 7 is rotatably connected to a reduction motor 13 that can drive it to rotate, and the reduction motor 13 is fixed at the inner upper end of the verification box 1;

[0064] The upper end of the vertical rod 8 is fixedly connected to the mounting frame 7 .

[0065] Furthermore, the reduction motor 13 is connected to the control panel 4 , and the control panel 4 is used to control the opening and closing of the reduction motor 13 .

[0066] When in use, the reduction motor 13 drives the mounting frame 7 to rotate, and the mounting frame 7 drives the vertical rod 8 to rotate, so that the thermometer and hygrometer installed on each vertical rod 8 can be rotated to the position of the glass observation window 6, so that the staff can read the value of the thermometer and hygrometer.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
