For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0026] References to "one embodiment" or "an example" or "an example" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment disclosed in the present application. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, one embodiment of the utility model shows a spectrometer, which includes a base 1 and a vernier disc assembly and a scale assembly which are arranged on the base 1 and can rotate relatively. The scale assembly and the vernier disc assembly are installed in the base 1 and the scale assembly and the vernier disc assembly are coaxially arranged, the scale assembly includes a scale disc 2, and the vernier disc assembly includes a vernier disc 3.

[0028] In this embodiment, the spectrometer further includes a protective cover 4, which is fixedly connected to the vernier disc assembly and movably connected to the base 1. The base 1 and the protective cover form a closed space that covers the scale plate 2 and the vernier disc 3. The protective cover 4 is provided with an observation portion opposite to the vernier disc 3, so that the relative position of the vernier disc 3 and the scale plate 2 can be observed through the observation portion. In actual setting, the optimal position of the observation portion is set at the position indicated by the scale of the vernier disc 3 and the scale plate 2, so that the user can face the scale value when observing, making the observation more accurate.

[0029] In this embodiment, a protective cover 4 fixedly connected to the vernier disk assembly is provided. When in use, the protective cover 4 rotates with the vernier disk assembly, so that when the spectrometer is in use and adjusted, the protective cover 4 can always form a shielding effect on the vernier disk 3 and the degree disk 2, thereby avoiding the wear and tear of the degree disk 2 and the vernier disk 3 caused by direct exposure to the external environment, thereby improving the service life. In addition, an observation portion is provided on the protective cover 4, so that the user can observe the relative position of the vernier disk 3 and the degree disk 2 through the observation portion, thereby avoiding the easy wear of the vernier disk 3 and the degree disk 2 caused by the exposed structure while ensuring the convenience of use of the spectrometer.

[0030] In order to facilitate observation of the relative positions of the vernier disc 3 and the degree disc 2 through the protective cover 4, in actual settings, the protective cover 4 can be made of a transparent material, and the observation portion can be marked on the protective cover 4. In this case, the design of the observation portion is only to facilitate the user to know that the positions of the vernier disc 3 and the degree disc 2 can be observed intuitively and accurately from here. Of course, in actual settings, the protective cover 4 can also be made of an opaque material, and the user can only observe at the observation portion, which can avoid interference with the user's observation caused by a large visible area.

[0031] See attached Figure 1In one embodiment of the present application, the observation part is set as an observation window 8 fixed on the protective cover 4, and the observation window 8 is provided with an observation port 5 that penetrates the protective cover 4, and the observation window 8 is provided with a protective cover 6 that can open or close the observation port 5. In this embodiment, the observation part is set as the observation window 8, and the protective cover 6 is set at the opening, so that during use, the user can control the opening and closing of the protective cover 6. Opening the protective cover 6 can observe the internal situation through the observation port 5, and closing the protective cover 6 can close the observation port 5, which has a protective effect and prevents dust or other impurities from entering the interior of the protective cover through the observation port 5. The opening and closing mode of the protective cover 6 can be set to rotating opening and closing or sliding opening and closing. Of course, it is also conceivable that an elastic member (spring or torsion spring) can be set at the installation position of the protective cover 6, and the elastic member keeps the protective cover 6 in a normally closed state (closes the observation port 5), so that the user can avoid forgetting to close the protective cover 6 after using the spectrometer, resulting in the problem of failure to provide protection. In actual setting, the shape of the observation port 5 can be set to be rectangular, circular, waist-shaped with an arc, or other shapes. Of course, the size of the observation port 5 can be reasonably selected according to actual conditions.

[0032] The observation window 8 and the protective cover 6 in this embodiment can be designed as a separate component, and the observation window 8 and the protective cover 6 can be assembled separately. A through hole corresponding to the observation port 5 of the observation window 8 is opened on the protective cover 4. During assembly, the observation window 8 is assembled on the protective cover 4, and the observation port 5 and the through hole on the protective cover 4 are mutually connected, so that the user can observe the vernier plate 3 and the scale plate 2 through the observation port 5 and the through hole on the observation window 8. The observation window 8 and the protective cover 4 can be fixedly connected by screws, and of course, they can also be fixedly connected by bonding. In addition, they can also be fixedly connected by magnetic attraction. Specifically, the protective cover 4 can be set to a magnetic material, such as steel or iron (of course, a magnet can also be set on the protective cover 4), and a magnet can be set on the observation window 8. In this way, the observation window 8 can be directly adsorbed on the protective cover 4 by the magnetic attraction effect of the magnet and the magnetic material or the magnetic force of the magnet, so that assembly and disassembly are more convenient.

[0033] In order to allow the user to better observe the scale value, the observation part in this embodiment is provided with a magnifying glass. The amplifier is installed in the observation part through a mounting part. In actual use, the distance between the magnifying glass and the cursor disk 3 is adjusted to a suitable distance to ensure that the user can easily adjust to a position where the magnified scale value can be observed during use. Since the magnifying glass generally adopts a convex lens, in actual use, the convex lens is installed in the observation part, so that the convex lens can not only play the effect of magnifying the scale value, but also can seal the edge of the convex lens and perform sealing treatment at the edge during installation, which can play a good protective effect. The magnifying glass can magnify the image of the observation area, thereby improving the accuracy of the reading.

[0034] The magnifying glass in this embodiment can be directly installed on the through hole of the protective cover 4, and of course can also be installed in the observation port 5 of the observation window 8.

[0035] Of course, it is conceivable that, in actual use, a magnifying glass can be installed at the observation port 5, or directly installed on the protective cover to form a mounting portion. Of course, a magnifying glass can also be omitted, and only a flat glass is needed so that people can observe the scale at the vernier disk 3.

[0036] See attached Figure 1 In one embodiment of the utility model, the number of observation parts is two, and the two observation parts are relatively distributed in different directions of the spectrometer. In this way, when using the spectrometer, users standing at different positions of the spectrometer can observe through observation parts in different directions, which is more convenient to use. In addition, it is also convenient for multiple people to collaboratively operate the spectrometer, and multiple operators can observe from observation parts in different directions respectively. Of course, it is conceivable that one observation part can also meet the use requirements, or in some cases, a larger number of observation parts can be set.

[0037] The distribution forms of the degree plate 2 and the vernier plate 3 of the utility model have the following two different embodiments. First, the degree plate 2 and the vernier plate 3 are distributed in parallel with each other in the vertical direction, and the vernier plate 3 is located on the upper part of the degree plate 2. At this time, the degree plate 2 and the vernier plate 3 are distributed in a stacked manner in the vertical direction. See the attached Figure 3At this time, the setting position of the observation part matches the distribution position of the scales of the dial 2 and the vernier dial 3. One way is to set the vernier dial 3 to a transparent material, and the scale of the dial 2 can be directly set on the end face of the dial 2. At this time, the observation part is set on the upper part of the vernier dial 3, and the user can see the scale on the dial 2 from above through the observation part through the vernier dial 3 made of transparent material. In the specific setting, an inclined portion can be set on the dial 2 and the vernier dial 3, and then the scale is set on the inclined portion. The setting of the inclined portion makes it convenient for the user to face the scale value with his / her line of sight, making observation more convenient. In addition, since the scale values ​​of the vernier dial 3 and the dial 2 are not necessarily set on the end faces, they may also be set on the side walls. At this time, in order to facilitate the observation of the relative positions of the vernier dial 3 and the dial 2 (determined by the relative scale values), it is generally required that the observation portion be located on the side of the vernier dial 3 and the dial 2, so that the user can observe the scale directly from the side. Of course, since it is set on the side, the user needs to bend over or squat to observe, which is inconvenient to use. At this time, it can be conceived that in order to facilitate the user to observe the corresponding scale value while standing, we can add a reflection component, and by adding a reflector, the scale value on the side is reflected so that it can be observed from above. Second, the degree dial 2 and the vernier disk 3 are distributed inside and outside. At this time, the degree dial 2 and the vernier disk 3 are nested, and the upper end surfaces of the two are set to be on the same horizontal plane. Scales are set on the upper end surfaces of the degree dial 2 and the vernier disk 3, respectively. At this time, for the convenience of observation, the observation part is set above the vernier disk 3 and the degree dial 2. Of course, in this embodiment, the observation part can also be set on the side walls of the vernier disk 3 and the degree dial 2. At this time, it is only necessary to set the degree dial 2 to a transparent material.

[0038] In order to better observe the relative positions of the degree plate 2 and the vernier plate 3, a lighting assembly is provided inside the protective cover 4 of the utility model. Due to the provision of the protective cover 4, the degree plate 2 and the vernier plate 3 are placed inside the protective cover 4 in a dark environment. When in use, the user cannot see the scale value from the outside, especially when the external environment light is poor, observation is particularly inconvenient. This embodiment provides a lighting assembly inside the protective cover 4, which can illuminate the inside of the protective cover 4 when in use, making it convenient for observation. The lighting assembly can be provided with multiple lamp bodies, and the multiple lamp bodies are evenly distributed in the protective cover 4. Of course, a corresponding lamp body can also be provided at the position of each observation part, so that the lamp body rotates with the rotation of the protective cover 4. In this way, no matter where the vernier plate assembly rotates to, the internal space of the protective cover 4 can be illuminated at any time, ensuring a better observation effect, which is particularly effective for use in a dark environment.

[0039] In one embodiment of the present application, the dial 2 is provided with a first scale line (not shown in the figure, the first scale line is a scale distributed in the circumferential direction), and the vernier plate 3 is provided with a second scale line 7 (the second scale line 7 can be designed as only a section of scale lines or an indicating arrow, and does not need to be distributed in the circumferential direction). The first scale line and the second scale line 7 are made of reflective materials, and cooperate with the lighting assembly set in the protective cover 4, so that the scale value appears particularly prominent. It is convenient for users to clearly observe the scale value.

[0040] Of course, it is conceivable that in order to observe the specific scale value more clearly, the first scale line and the second scale line can be distinguished by different colors, so that when observing, the comparison between the two can be seen more intuitively, avoiding the problem of visual errors caused by long-term operation of the spectrometer to observe the scale value.

Those skilled in the art should understand that the present application includes but is not limited to the contents described in the drawings and the above specific embodiments.
