The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0019] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] Reference Figures 1 to 4This application provides a portable refractometer for aircraft de-icing and anti-icing fluid, including a carrying case 1. The carrying case 1 houses the main body 7 of the refractometer and its components, providing a carrier for installation and protection of the entire device. A side plate 6 is hinged to the right side of the carrying case 1. The side plate 6 can rotate around the hinge, thereby opening and closing the carrying case 1. When the side plate 6 is closed, it can protect the main body 7 of the refractometer inside. A buckle 5 is provided between the carrying case 1 and the side plate 6, which is used to fix the side plate 6 to the carrying case 1 to prevent the side plate 6 from accidentally opening during movement.

[0021] The front of the portable case 1 is equipped with a movable component 2, which facilitates the movement of the entire device by the operator. The movable component 2 includes a movable cylinder 21, which provides guidance and support for the movement of the first screw 25. A crossbar 22 is fixedly installed at the bottom of the movable cylinder 21, and the crossbar 22 is hinged to the front of the portable case 1, allowing the movable cylinder 21 to rotate around the hinge point between the crossbar 22 and the portable case 1, making it easy to fold up when not in use. Universal wheels 27 are fixedly installed at each of the four corners of the bottom of the portable case 1, facilitating flexible movement of the device and easily changing its direction of movement.

[0022] The portable case 1 houses a refractometer body 7, which measures the refractive index of aircraft de-icing and anti-icing fluid. It can be removed from the portable case 1 for convenient handheld use or placement for measurement. A nut 24 is fixedly mounted on the top of the moving cylinder 21, engaging with a first screw 25 to allow for vertical movement. The first screw 25 is screwed into the nut 24, with its lower portion inserted into the moving cylinder 21. An adjusting rod 23 is fixedly mounted on the top of the first screw 25, and a handle 26 is fixedly mounted on the top of the adjusting rod 23. Rotating the handle 26 rotates the adjusting rod 23 and the first screw 25. Because the first screw 25 is screwed into the nut 24, and the moving cylinder 21 guides the first screw 25, it can move vertically within the moving cylinder 21, thus adjusting the height of the handle 26 for easy gripping and movement of the equipment. The lead angle of the first screw 25 is smaller than the equivalent friction angle, giving it a self-locking function that can fix the handle 26 at the required height, preventing it from descending on its own during movement. The outer side of the first screw 25 is coated with a strong-adhesion, anti-leakage, wear-resistant, and anti-contamination grease. This grease reduces friction between the first screw 25 and the nut 24, improving service life, and preventing impurities from entering the thread clearance and affecting normal use.

[0023] The portable case 1 contains an installation component 3. This component temporarily secures the refractometer body 7 inside the case during transport, preventing damage from movement. The refractometer body 7 can be removed by loosening the installation component 3. The installation component 3 includes a positioning groove 31 and side blocks 32. Both the positioning groove 31 and the side blocks 32 are fixedly installed on the inner bottom of the portable case 1. The rear bottom of the refractometer body 7 is inserted into the positioning groove 31, which positions the rear end of the refractometer body 7. The two side blocks 32 are respectively attached to the left and right sides of the bottom of the refractometer body 7, limiting its movement from the left and right sides.

[0024] A second screw 33 is threaded through the front inner wall of the portable case 1. A first knob 35 is fixedly installed on the front of the second screw 33. Rotating the first knob 35 can drive the second screw 33 to rotate. A clamping plate 34 is rotatably connected to the back of the second screw 33. The clamping plate 34 is slidably connected to the inner bottom of the portable case 1. When the second screw 33 rotates, because the second screw 33 is threaded to the front inner wall of the portable case 1, the second screw 33 will drive the clamping plate 34 to slide back and forth in the inner bottom of the portable case 1. The clamping plate 34 is attached to the front of the refractometer body 7. By adjusting the position of the clamping plate 34, the front of the refractometer body 7 can be clamped, further enhancing the stability of the refractometer body 7 in the portable case 1. When removing the refractometer body 7, simply rotate the first knob 35 in the opposite direction to disengage the clamping plate 34 from its front. The second screw 33 has a thread lead angle smaller than the equivalent friction angle, providing self-locking performance. This allows it to fix the clamping plate 34 in the desired position, ensuring stable clamping of the refractometer body 7 during transportation. The outer side of the second screw 33 is coated with the same grease as the first screw 25 to reduce friction and prevent contamination.

[0025] The bottom of the portable case 1 is equipped with a fixing component 4. The function of the fixing component 4 is to increase friction with the ground during transportation, ensuring the stability of the overall equipment and preventing the portable case 1 from shaking violently due to road bumps during transportation. The fixing component 4 includes a support plate 41, which contacts the ground to increase the contact area between the equipment and the ground and improve stability. A lifting plate 42 is fixedly installed on the left side of the support plate 41, and the lifting plate 42 is used to drive the support plate 41 to move up and down. A fixing plate 43 is fixedly installed on the left side of the portable case 1, and the fixing plate 43 provides mounting support for the third screw 44. The third screw 44 is screwed through the inside of the fixing plate 43. The bottom of the third screw 44 is rotatably connected to the top of the lifting plate 42. A second knob 45 is fixedly installed on the top of the third screw 44. Turning the second knob 45 can drive the third screw 44 to rotate. Since the third screw 44 is screwed to the fixing plate 43, the third screw 44 will drive the lifting plate 42 to move up and down, and thus drive the support plate 41 to move up and down. During transport, rotating the second knob 45 moves the support plate 41 downwards to make it in close contact with the ground, thereby enhancing the overall stability of the equipment. When the equipment needs to be moved, the support plate 41 is moved upwards to lift it off the ground, avoiding affecting the movement function of the casters 27. A limit rod 46 is fixedly installed on the top of the lifting plate 42. The limit rod 46 moves through the interior of the fixed plate 43 and guides and limits the movement of the lifting plate 42, preventing it from rotating during movement. The thread lead angle of the third screw 44 is less than the equivalent friction angle, enabling self-locking and fixing the support plate 41 at the required height. The outer side of the third screw 44 is also coated with the aforementioned grease to ensure its normal operation.

[0026] The working principle of this invention is as follows: When the instrument needs to be transported, the side panel 6 is opened via the buckle 5, and the main body 7 of the refractometer is placed inside the carrying case 1, so that the bottom rear end of the main body 7 is inserted into the positioning groove 31, and the left and right sides are in contact with the side blocks 32. Then, the first knob 35 is turned, driving the second screw 33 to rotate, causing the clamping plate 34 to move backward and fit against the front of the main body 7 of the refractometer, clamping and fixing it. The side panel 6 is closed and fixed with the buckle 5. Next, the second knob 45 is turned, driving the third screw 44 to rotate, causing the lifting plate 42 to move downward, thereby driving the support plate 41 to move downward until the support plate 41 is in close contact with the ground, ensuring the overall stability during transportation. Then, the handle 26 is turned to adjust the position of the first screw 25 in the moving cylinder 21, so that the handle 26 is at a suitable height. Holding the handle 26, the universal wheels 27 at the bottom of the carrying case 1 are used to push the equipment for transportation.

[0027] When you arrive at the location where you need to use the main body 7 of the refractometer, first turn the second knob 45 to retract the support plate 41, then open the side plate 6 through the buckle 5, turn the first knob 35 in the opposite direction to move the clamp 34 forward and away from the front of the main body 7 of the refractometer, and take the main body 7 of the refractometer out of the carrying case 1, and you can then measure the refractive index of the aircraft de-icing and anti-icing fluid.

[0028] After use, put the main body 7 of the refractometer back into the carrying case 1, fix it in place according to the above-mentioned pre-transportation fixing steps, close the side panel 6, and it can be transported or stored again.

[0029] Furthermore, all contents not described in detail in this specification are existing technologies known to those skilled in the art, and all electrical components mentioned in this document are powered by external power supply lines.
