[0002] Food directly affects people's health and even life. Therefore, before food leaves the factory and enters the market, it needs to pass the experimental tests of relevant departments to ensure the safety of food when consumed. Food testing mainly detects whether the toxic and harmful substances in food exceed the relevant national or local enterprise standards to minimize food safety risks. The principle of infrared spectroscopy technology when applied to food testing is that the vibration or rotation frequency of a certain group in the molecules of food substances can be consistent with the frequency of infrared light, and its molecules can absorb the energy of infrared spectrum. The absorption of infrared light by molecules is recorded by instruments to obtain infrared spectrum. Through the changes in the image of infrared spectrum, the molecular structure of the test object can be determined to achieve the purpose of detecting food ingredients.

[0023] See also Figure 1-4 The utility model provides the following technical solutions: a near-infrared spectroscopy portable food detection device, comprising an infrared spectrometer detector body 1, a fixing frame 2 is fixedly connected to one side of the infrared spectrometer detector body 1, an optical fiber probe 3 is arranged on the fixing frame 2, a data line 6 is fixedly connected to the optical fiber probe 3, a chamber 7 is arranged at the bottom of the fixing frame 2, a rotating shaft 10 is rotatably connected inside the chamber 7, a positioning clamp is arranged on the rotating shaft 10, one end of the rotating shaft 10 passes through the fixing frame 2 and is fixedly connected to a turntable 12, a limiting component is fixedly connected to the fixing frame 2, an opening is arranged at one side of the chamber 7, a slot body 4 is arranged on the infrared spectrometer detector body 1, a liquid transmission module is arranged inside the slot body 4, a support plate 5 is fixedly connected to the fixing frame 2, a groove 20 is arranged at the top of the infrared spectrometer detector body 1, and a handle 21 is arranged inside the groove 20.

[0024] In a specific embodiment of the utility model, food liquid contained in a sample bottle is inserted into the liquid transmission module and detected by the liquid transmission module; when it is necessary to detect the sample contained in the container, the optical fiber probe 3 is used for detection; the cooperation between the groove 20 and the handle 21 makes the device more convenient to carry; when it is necessary to store the data cable 6, the plug of the data cable 6 is separated from the infrared spectrometer body 1, and then the end of the data cable 6 close to the plug is fixed on the positioning clamp through the opening, and then the turntable 12 is rotated, and the turntable 12 drives the rotating shaft 10 to rotate, so that the excess data cable 6 is wound around the outside of the rotating shaft 10, and then the turntable 12 is fixed by the limit assembly to prevent it from rotating, so that the storage of the data cable 6 can be completed, making the device more regular and improving its portability. At the same time, the data cable 6 can be protected to prevent the wire from being damaged when not in use, and has a good protection effect. When the data cable 6 needs to be taken out, the limit of the turntable 12 by the limit assembly is released, and then the data cable 6 wrapped around the outside of the shaft 10 can be unfolded, and the limit of the end of the data cable 6 by the positioning clamp is released, so that the data cable 6 can be pulled out of the chamber 7. The operation is simple and quick.

[0025] Specifically, the positioning clamp includes an arc-shaped pressure plate 11 , both ends of which are fixedly connected with an insertion rod 19 , a connecting hole 18 is provided on the rotating shaft 10 , a coil spring 17 is provided inside the connecting hole 18 , and the coil spring 17 is fixedly connected to the insertion rod 19 .

[0026] In this embodiment: the arc pressure plate 11 is pulled, and the arc pressure plate 11 stretches the coil spring 17 by driving the insertion rod 19, so that the distance between the arc pressure plate 11 and the rotating shaft 10 is increased, and then the plug of the data cable 6 is passed through the arc pressure plate 11 and the rotating shaft 10, and the arc pressure plate 11 is released. Under the action of the coil spring 17, the arc pressure plate 11 is reset and squeezes the data cable 6. Since the plug of the data cable 6 is relatively large, the data cable 6 is stuck on the rotating shaft 10.

[0027] Specifically, the limiting assembly includes a screw rod 15 threadedly connected to the fixing plate 8 , and a pressure plate 14 is fixedly connected to the end of the screw rod 15 .

[0028] In this embodiment, the pressure plate 14 is rotated, and the pressure plate 14 drives the screw 15 to rotate and move toward the side close to the fixed plate 8, so that the pressure plate 14 squeezes one side of the rotating disk 12, limits the rotating disk 12, and prevents it from rotating by itself.

[0029] Specifically, a rubber plate 13 is provided on one side of the rotating disk 12 close to the pressure plate 14 .

[0030] In this embodiment, the rubber plate 13 is used to increase the contact area between the rotating disk 12 and the pressure plate 14, so that the pressure plate 14 has a better limiting effect.

[0031] Specifically, an anti-slip groove is provided on the outer circumference of the turntable 12 .

[0032] In this embodiment, by providing an anti-skid groove on the outer side of the turntable 12 , the friction between the fingers and the turntable 12 can be increased, making the rotation of the turntable 12 more labor-saving.

[0033] Specifically, a clamping sleeve 9 is provided on the top of the support plate 5 .

[0034] In this embodiment, by arranging the ferrule 9 on the support plate 5, the optical fiber probe 3 can be placed more securely and its structural stability can be improved.

[0035] Specifically, a cover body 16 is provided on the liquid transmission module.

[0036] In this embodiment, by providing the cover 16, it is possible to prevent foreign matter from entering the insertion hole of the liquid transmission module, so that the device can maintain a good use effect.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
