[0016] The following is combined with Figure 1-3 This application is described in further detail.

[0017] The embodiment of the present application discloses a portable infrared spectrometer, including a spectrometer body 1 and a scanning head 5. A handle 2 is fixedly connected to the bottom of the spectrometer body 1, the scanning head 5 is located on one side of the spectrometer body 1, and a protective frame 3 is fixedly connected to the side of the spectrometer body 1 close to the scanning head 5. The protective frame 3 surrounds the surface of the scanning head 5, and sliding grooves 6 are opened on both sides of the protective frame 3. Baffles 7 are arranged in the sliding grooves 6, and the baffles 7 are connected to the protective frame 3 through an opening and closing mechanism.

[0018] Furthermore, the opening and closing mechanism includes a first tooth plate 11, which is provided with two groups, and the two groups of first tooth plates 11 are respectively fixedly installed on the surface of the baffle 7, the two groups of first tooth plates 11 are symmetrically arranged, and a gear 12 is arranged between the two groups of first tooth plates 11, and the gear 12 is rotatably installed on the surface of the protective frame 3, and the surface of the protective frame 3 is provided with a driving mechanism for driving the gear 12 to rotate.

[0019] Furthermore, the driving mechanism includes a second tooth plate 13 , and the second tooth plate 13 is meshed with the gear 12 , the second tooth plate 13 is arranged perpendicular to the scanning head 5 , and the second tooth plate 13 is installed on the surface of the spectrometer body 1 by providing a buffer mechanism.

[0020] Furthermore, at least two groups of buffer mechanisms are provided, and the two groups of buffer mechanisms are provided on both sides of the protection frame 3 .

[0021] Furthermore, the buffer mechanisms include a guide rod 9 fixedly installed on a slide seat 8, the slide seat 8 is slidably connected inside with a guide rod 9 arranged parallel to the second tooth plate 13, one end of the guide rod 9 is fixedly connected with a connecting plate 14, and the other end of the guide rod 9 is fixedly connected with a buffer plate 4, a spring 10 is sleeved on the surface of the guide rod 9, one end of the spring 10 is fixedly connected to the connecting plate 14, one end of the spring 10 is fixedly connected to the slide seat 8, and the connecting plate 14 close to the driving mechanism side is fixedly connected to the second tooth plate 13.

[0022] In this embodiment, when not in use, the two baffles 7 are closed and arranged on the surface of the protection frame 3, which can protect the scanning head 5 and prevent the scanning head 5 from being damaged by collision.

[0023] During actual use, when detecting the object to be tested, it is necessary to move the scanning head 5 of the spectrometer body 1 close to the object to be tested. By setting a buffer mechanism, when the spectrometer body 1 is close to the object to be tested, the buffer plate 4 first contacts the object to be tested, and in the process of continuously moving the spectrometer body 1, the second tooth plate 13 and the slide 8 move relative to each other, and the second tooth plate 13 drives the gear 12 to rotate. Since the gear 12 is meshed with the first tooth plate 11, the two first tooth plates 11 move, thereby driving the two baffles 7 to open, exposing the scanning head 5, and the scanning head 5 can detect the object to be tested.

[0024] In addition, by providing the spring 10 , when the second tooth plate 13 moves due to an external force, the spring 10 will undergo elastic deformation. When the external force on the second tooth plate 13 is released, the spring 10 will restore, thereby driving the second tooth plate 13 to return to its original position.
