[0002] A spectrometer is an instrument for measuring angles. Its basic principle is to let light pass through a slit and a focusing lens to form a beam of parallel light, which enters the telescope objective lens after reflection or refraction and forms an image on the focal plane of the telescope. The deflection angles of various light rays are observed and measured through the eyepiece to obtain optical parameters, etc.

[0003] When the spectrometer is actually used, in order to ensure better measurement results, it is necessary to adjust the positions of the various components to achieve the best measurement position. During the specific adjustment, it is generally adjusted by changing the relative positions of the degree dial and the vernier disk. Current technology generally changes the relative positions of the degree dial and the vernier disk by adjusting the rotation of the vernier disk assembly. However, such an adjustment structure is too simple and sometimes causes inconvenience in operation due to the relative position of the operator and the instrument. Utility Model Content

[0031] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments based on the embodiments are intended to be used to explain the present application and cannot be understood as limiting the present application.

[0032] 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.

[0033] See attached Figure 1-7 One of the embodiments of the utility model discloses a spectrometer, including a base 1, a dial assembly, a vernier disk assembly and an adjusting device, the dial assembly and the vernier disk assembly are installed in the base 1 and are coaxially arranged, the dial assembly includes a first main shaft 21 and a dial 22, the dial 22 is fixedly connected to the first main shaft 21, the vernier disk assembly includes a second main shaft 31 and a vernier disk 32, the vernier disk 32 is fixedly connected to the second main shaft 31, the second main shaft 31 is a sleeve structure sleeved on the first main shaft 21 and is rotatably connected to the first main shaft 21, in actual setting, the outer wall of the first main shaft 21 and the inner wall of the second main shaft 31 fit each other, so that the stability of the connection between the two can be ensured, and the coaxiality can be ensured.

[0034] The adjustment device in this embodiment includes a first adjustment component 4, the first adjustment member is used to adjust the position of the degree plate component, the first adjustment component 4 includes a locking link 41, one end of the locking link 41 is connected to the first spindle 21, the other end of the first adjustment component 4 passes through the side wall of the base 1 and extends to the outside of the base 1, and the rotation of the locking link 41 can drive the degree plate 22 to rotate relative to the vernier plate 32 through the first spindle 21. This embodiment adjusts the relative position of the degree plate 22 to the vernier plate component by adjusting the rotation of the degree plate 22. Compared with the structure of adjusting the vernier plate 32 in the prior art, another adjustment method is provided, which enriches the adjustment means and makes the adjustment more convenient.

[0035] In one embodiment of the utility model, the scale plate 22 and the vernier plate 32 are arranged in parallel with each other in the axial direction. In actual installation, the scale plate 22 is located below the vernier plate 32, and the two are arranged side by side, which is different from the structure of the scale plate 22 and the vernier plate 32 being arranged inside and outside in the prior art. Such a structure makes assembly more convenient, and there is no need to consider the production of the matching size between the two, and they can be processed separately, and only the assembly accuracy needs to be ensured, which improves the production cost and efficiency of the parts.

[0036] See attached Figure 2 , 6 The first adjustment assembly 4 of the utility model also includes a stop rod 42. One end of the locking link 41 is rotatably sleeved on the first main shaft 21. The stop rod 42 is arranged on the locking link 41 and has a threaded section that is threadedly matched with the locking link 41. One end of the stop rod 42 is formed with a screw cap 421 placed outside the base 1. Since the stop rod 42 is threadedly connected to the locking link 41, rotating the stop rod 42 will loosen or tighten the outer wall of the first main shaft 21 under the action of the thread force. When the stop rod 42 is pressed against the first main shaft 21, the first main shaft 21 is locked by cooperating with the locking link 41. At this time, the movement of the locking link 41 will drive the first main shaft 21 to move together, thereby achieving the effect of adjusting the dial 22 by adjusting the locking link 41. See attached Figure 4 , 5 One end of the locking link 41 in this embodiment is formed with a sleeve structure that is sleeved on the first main shaft 21. In this way, when the locking link 41 cooperates with the stop rod 42 to lock the first main shaft 21, the first main shaft 21 can be locked from multiple directions through the sleeve structure, thereby improving the stability of locking the first main shaft 21. Moreover, the sleeve structure of the locking link 41 can also limit the position of the locking link 41 by cooperating with the first main shaft 21, thereby reducing the radial shaking of the locking link 41 during the adjustment process and improving the stability during the adjustment process.

[0037] When the stop rod 42 is loosened from the first main shaft 21 by screwing, the locking link 41 can move relative to the first main shaft 21. Figure 6 The first adjustment assembly 4 also includes a mounting seat 48, which is fixed on the outer wall of the base 1. A slide groove is formed on the mounting seat 48, and the locking link 41 passes through the slide groove. In addition to being able to better guide the locking link 41 and make its movement more stable, the width of the slide groove will also limit the rotation range of the locking link 41, that is, limit the adjustment range of the dial 22. Of course, in actual use, the adjustment of the dial 22 is fine-tuning, and the width of the slide groove can generally meet the adjustment requirements. However, when a larger adjustment range is required, the locking screw in the present application can move in the opposite direction after loosening the first spindle 21, and then lock the first spindle 21. At this time, the rotation of the dial 22 can continue to be adjusted in the same direction based on the original adjustment. It can be seen that by setting the structure of the stop rod 42 and the locking link 41, it is not only convenient for the operator to operate on the side of the spectrometer, but also can provide a larger adjustment range for the dial 22.

[0038] In order to better lock the first spindle 21, a stop block 43 is provided at one end of the stop rod 42 in this embodiment, and an arc groove that is contoured to the arc surface of the outer wall of the first spindle 21 is provided at one end of the stop block 43. The arc groove can provide a larger contact area between the stop block 43 and the side wall of the first spindle 21, so that the stop rod 42 can better lock the first spindle 21. Of course, in actual setting, the arc groove can also be directly formed at the end of the stop rod 42.

[0039] In order to achieve a more precise adjustment effect (to achieve fine adjustment of the degree plate 22), the first adjustment assembly 4 also includes a first push rod 44 set on the mounting seat 48, the first push rod 44 is threadedly connected to the base 1, and one end of the first push rod 44 extends into the slide groove and presses on the side wall of the locking link 41. Rotating the first push rod 44 can push the locking link 41 to rotate in the slide groove under the action of the thread. The threaded connection between the first push rod 44 and the mounting seat 48 facilitates the control of the adjustment amount and achieves a fine adjustment effect, and the position of the adjusted degree plate assembly can be fixed by the thread locking force.

[0040] In order to realize the bidirectional adjustment of the dial assembly and improve the convenience of adjustment, the mounting seat 48 of the utility model is further provided with a first spring seat 45 arranged opposite to the first push rod 44, the locking link 41 is arranged between the first spring seat 45 and the first push rod 44, and a first spring 46 is connected between the first spring seat 45 and the locking link 41. The first spring 46 in this embodiment is always in a compressed state, and the first push rod 44 and the locking link 41 can always keep in contact during the adjustment process through the first spring 46, avoiding the problem of inaccurate adjustment caused by the assembly gap, and the first spring 46 can also loosen the first push rod 44 when reverse adjustment is required, and the locking link 41 will push the locking screw to move in the reverse direction under the elastic force of the first spring 46, thereby realizing the reverse adjustment of the dial assembly.

[0041] Of course, it is conceivable that in actual use, since the spring has a certain elasticity, it may be deformed when subjected to pressure compression. In order to ensure stability, a guide rod 47 can be added to the first spring seat 45, and a guide hole for installing the guide rod 47 can be opened on the first spring seat 45. The guide rod 47 is slidably connected in the guide hole to achieve a sliding connection with the first spring seat 45. The first spring 46 is installed in the guide hole, one end of the first spring 46 is connected to the bottom wall of the guide hole (i.e., the first spring seat 45), and the other end is connected to the guide rod 47 so that one end of the push rod is always against the locking link 41, so that stability can be guaranteed during the adjustment process.

[0042] The vernier disk assembly of the utility model includes a stop ring 34 and a stop frame 35. The upper end of the base 1 is provided with a stopper, the stop ring 34 is installed in the stopper, and the stop frame 35 is fixedly connected to the stop ring 34. The spectrometer also includes an upper shell 33, which is fixedly connected to the second spindle 31 and forms a structure with the base 1 to seal the scale assembly and the vernier disk assembly. In the specific design, in order to ensure the overall appearance of the spectrometer, the joint of the upper shell 33 and the base 1 is positioned by plane to ensure that the upper shell 33 can be rotated relative to the base 1 to improve the stability of the fit.

[0043] In actual use, the entire cursor disk assembly can be driven to rotate by directly controlling the rotation of the upper shell 33, and the position of the cursor disk assembly can be adjusted (the adjustment process is changed to coarse adjustment). It should be noted that the active light tube 11 of the spectrometer is fixed together with the cursor disk assembly, and the fixed light tube 12 is fixed on the base 1. The adjustment of the assembly of the cursor disk 32 can also adjust the relative position of the active light tube 11 and the fixed light tube 12.

[0044] In order to fine-tune the position of the cursor assembly, the utility model is provided with a positioning screw 36 for fixing the stop ring 34 on the outer wall of the base 1, and the positioning screw 36 is threadedly connected to the base 1. One end of the positioning screw 36 in this embodiment can be pressed against the side wall of the stop ring 34. Since the positioning screw 36 is fixed on the side wall of the base 1, the positioning screw 36 is pressed against the side wall of the stop ring 34 to fix the position between the stop ring 34 and the base 1. Of course, it should be noted that, see the attached Figure 1 , 2 3. In order to make the overall structure more compact, the positioning screw 36 in the utility model can be directly set on the mounting seat 48, so that the positioning screw 36 and the operating position of the first adjustment component 4 are located in the same area, which is convenient for operation.

[0045] The fixed stop ring 34 and the stop frame 35 serve as the basis for fine adjustment of the vernier disc assembly. The adjustment device in this embodiment also includes a second adjustment assembly 5, see the attached Figure 7 The second adjustment assembly 5 is used to adjust the position of the cursor assembly in the circumferential direction of the base 1. The second adjustment assembly 5 includes a second push rod 51 and a second spring seat 52. The second push rod 51 is threadedly connected to the upper shell 33 and one end of the second push rod 51 extends into the interior of the upper shell 33 and presses on the stop frame 35. The upper shell 33 is provided with a second spring seat 52 arranged opposite to the second push rod 51. The stop frame 35 is arranged between the second push rod 51 and the second spring seat 52. A second spring 53 is connected between the second spring seat 52 and the stop frame 35. The second push rod 51 and the second spring seat 52 can be used to precisely fine-tune the cursor assembly. The specific adjustment method and beneficial effects are similar to the first push rod 44 and the first spring 46 in the above-mentioned first adjustment assembly 4, and will not be repeated here.

[0046] It can be seen that compared with the prior art, the present application changes the installation method of the dial assembly and the vernier disk assembly, so that the dial 22 and the vernier disk 32 are arranged in parallel and spaced apart, and a first adjustment assembly 4 for fine-tuning the dial 22 is added. By designing the structure and position of the first adjustment assembly 4, it is more convenient for the operator to operate, and the adjustment method of the coarse adjustment and fine adjustment of the vernier disk assembly by the second adjustment member at the same time further enriches the adjustment means during the use of the spectrometer and makes the adjustment more convenient.

[0047] The above are only specific embodiments of the present application, but the protection scope of the present application is not limited thereto. 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. Any modification that does not deviate from the functional and structural principles of the present application will be included in the scope of the claims.
