[0041] The above technical objectives of this utility model are mainly achieved through the following technical solutions:
[0042] Embodiment 1:
[0043] As Figures 1 to 3 shown, this utility model provides a spectrometer camera adapter, which includes: a fixed seat 10, fixed on the light output hole of the spectrometer, and the fixed seat 10 is provided with a limiting groove 14 extending along the axis direction of the light output hole; a moving unit, arranged in the fixed seat 10, the moving unit has a limiting member and a light passing hole 33, the limiting member is inserted into the limiting groove 14, the axis of the light passing hole 33 coincides with the axis of the light output hole, and one end of the light passing hole 33 is formed with an interface for connecting the camera 42; a driving unit, arranged in the fixed seat 10, the driving unit is connected to the moving unit to drive the moving unit to reciprocate in the fixed seat 10 along the limiting groove 14.
[0044] The spectrometer camera adapter described in the present utility model mainly consists of a fixed seat 10, a moving unit, and a driving unit. It has a simple structure, is convenient to assemble, and easy to operate. By driving the movement of the moving unit through the driving unit, the position coincidence of the camera 42 and the spectrometer focus can be effectively adjusted, enabling the spectrum to present a clear image and improving the test performance of the spectrometer.
[0045] The following will detail the specific structures of the various parts of the spectrometer camera adapter described in the present utility model, as well as the positional and connection relationships between the various parts.
[0046] As Figures 1 to 3 shown, the spectrometer camera adapter described in the present utility model, as an interface device, is installed on the light output hole of the spectrometer, and the camera 42 required by the spectrometer can be installed on this adapter.
[0047] The spectrometer camera adapter includes a fixed seat 10. As Figure 2 and Figure 3 shown, the fixed seat 10 is a disc-shaped structure matching the light output hole on the side wall 41 of the spectrometer. It is embedded in the light passing hole 33 and fixed to the side wall 41 of the spectrometer by bolts 15. The axis of the fixed seat 10 coincides with the axis of the light output hole, and a through hole for light to pass through is formed at the center of the fixed seat 10.
[0048] Furthermore, as Figure 3 shown, the fixed seat 10 is provided with a limiting groove 14 extending along the axis direction of the light output hole. In this embodiment, the limiting groove 14 is opened on the outer peripheral wall of the central through hole of the fixed seat 10. In other embodiments of the present utility model, the limiting groove 14 can be correspondingly opened according to the installation position of the moving unit, as long as it is ensured that the limiting member of the moving unit can be clamped in the limiting groove 14. The opening position of the limiting groove 14 is not limited herein.
[0049] The spectrometer camera adapter further includes a moving unit. As Figure 1 and Figure 2 shown, the moving unit is usually assembled from multiple components. The moving unit is installed in the central through hole of the fixed seat 10 and can move along the axis direction of this central through hole. The moving unit has a limiting member, and the limiting member is inserted into the limiting groove 14 of the fixed seat 10 to circumferentially limit the moving unit and prevent the moving unit from rotating around the axis of the central through hole. A light passing hole 33 for light to pass through is formed at the center of the moving unit. The axis of the light passing hole 33 coincides with the axis of the light output hole. An interface is formed at one end of the light passing hole 33 facing the outside of the spectrometer. This interface is usually a threaded interface, and the camera 42 is threadedly connected to this interface. The light generated inside the spectrometer can enter the camera 42 through the light passing hole 33. At the same time, the camera 42 installed on the interface can move back and forth in the central through hole of the fixed seat 10 along with the moving unit.
[0050] The spectrometer camera adapter further includes a driving unit, such as Figure 1 and Figure 2 As shown, the driving unit is usually assembled by multiple components and serves as a transmission member for driving the movement of the moving unit. The driving unit can drive the moving unit in various driving manners. In one embodiment, a screw driving pair is provided between the driving unit and the moving unit, and at the same time, the axial position of the driving unit is defined. By manually or electrically rotating the rotating member in the driving unit, under the action of the screw driving pair and the limiting groove 14, the rotation of the rotating member will be converted into the movement of the moving unit; In one embodiment, the driving unit can adopt a micro cylinder or a micro oil cylinder, connect the output shaft of the cylinder or the oil cylinder to the moving unit (for example, connect to the limiting member), and then drive the moving unit to move back and forth through the expansion and contraction of the output shaft; In one embodiment, the driving unit can also directly adopt the way of a manual push-pull rod, connect one end of the push-pull rod to the moving unit, and the other end extends out of the fixed seat 10 for the experimenter to push and pull. The driving unit can select a suitable structural form according to the actual accuracy requirements, and no specific limitation is made here.
[0051] According to an embodiment of the present invention, as Figure 2 shown, the driving unit includes a turntable 20 and a rotating ring 21. The turntable 20 is threadedly connected to the circumferential outside of the rotating ring 21. The turntable 20 is clamped in the fixed seat 10 and can rotate relative to the fixed seat 10. The rotating ring 21 is connected to the limiting member; wherein, in the state of rotating the turntable 20, the rotating ring 21 can drive the moving unit to reciprocate along the limiting groove 14.
[0052] In this embodiment, the driving unit adopts a screw driving pair structure, with high control precision and convenient operation for experimenters.
[0053] Specifically, as Figure 2 and Figure 3 shown, a limiting ring 11 is formed on the fixed seat 10. The axis of the limiting ring 11 coincides with the axis of the light-emitting hole. An installation channel 12 is formed inside the limiting ring 11. The moving unit is slidably arranged in the installation channel 12. An adjustment ring groove 13 is formed on the circumferential outside of the limiting ring 11. The turntable 20 and the rotating ring 21 are arranged in the adjustment ring groove 13. The limiting groove 14 is opened on the limiting ring 11. That is, the moving unit is installed inside the limiting ring 11, the turntable 20 and the rotating ring 21 are sleeved outside the limiting ring 11, and the rotating ring 21 is connected to the moving unit through a limiting member passing through the limiting groove 14. The moving unit and the rotating ring 21 form an integral structure through the limiting member and can move together in the fixed seat 10 along the limiting groove 14. Among them, the turntable 20, the rotating ring 21 and the moving unit are all coaxially arranged.
[0054] The circumferential outer side of the swivel ring 21 has external threads, and the circumferential inner side of the turntable 20 has internal threads that cooperate with the above-mentioned external threads, and the two are connected by threads; the turntable 20 is clamped in the fixed seat 10 to axially limit the turntable 20, and the turntable 20 can rotate relative to the fixed seat 10 around the axis of the turntable 20. When the experimenter rotates the turntable 20, under the action of the screw drive pair and the limiting groove 14, the rotation of the turntable 20 will be converted into the movement of the swivel ring 21 and the moving unit.
[0055] Preferably, as Figure 2 shown, the turntable 20 includes a threaded portion 22 and a manual adjustment portion 23 that are vertically connected. One end of the limiting ring 11 is connected with an end cover 40 to close the adjustment ring groove 13. The threaded portion 22 is threadedly connected with the swivel ring 21 and is located in the adjustment ring groove 13, and the manual adjustment portion 23 extends to the outside of the adjustment ring groove 13.
[0056] Specifically, an end cover 40 is connected to the end of the limiting ring 11 facing the outside of the spectrometer by screws. The end cover 40 is located at the top of the adjustment ring groove 13. While closing the adjustment ring groove 13, it can also limit the axial position of the turntable 20. A part of the turntable 20 is clamped in the adjustment ring groove 13 by the end cover 40 and is threadedly connected with the swivel ring 21, and the other part is located outside the adjustment ring groove 13, which is convenient for the experimenter to manually rotate the turntable 20.
[0057] According to an embodiment of the present invention, as Figure 2 shown, the moving unit includes a sliding ring block 30, a camera connecting piece 31 and a guiding pin 32. The sliding ring block 30 is arranged in the installation channel 12. The middle through hole of the sliding ring block 30 forms a light passing hole 33. The guiding pin 32 forms a limiting member, and both ends of the guiding pin 32 are respectively connected with the sliding ring block 30 and the swivel ring 21. The camera connecting piece 31 is arranged at one end of the sliding ring block 30 to form the interface for connecting the camera 42.
[0058] Specifically, the sliding ring block 30 is a ring-shaped columnar member with a through hole in the middle. Through holes corresponding to the limiting groove 14 are opened on the circumferential outer side wall thereof. Through holes corresponding to the position of the limiting groove 14 are also opened on the circumferential inner side wall of the swivel ring 21. One end of the guiding pin 32 inserted in the limiting groove 14 is inserted into the side wall through hole of the sliding ring block 30, and the other end of the guiding pin 32 is inserted into the side wall through hole of the swivel ring 21. The end of the sliding ring block 30 facing the outside of the spectrometer has a mounting hole. The outer side surface of the camera connecting piece 31 is trapezoidal. By tightening the above trapezoidal surface with a set screw, the camera connecting piece 31 is tightened into the mounting hole of the sliding ring block 30, so that the end surface of the camera connecting piece 31 is closely attached to the end surface of the sliding ring block 30, ensuring that the mounting surface of the camera 42 is parallel to the side wall 41 of the spectrometer box body.
[0059] According to an embodiment of the present invention, as Figure 2 andFigure 3 As shown, along the circumferential direction of the limit ring 11, a plurality of limit grooves 14 are spaced apart on the limit ring 11, and at least one guide pin 32 is inserted into each limit groove 14. The plurality of limit grooves 14 are evenly distributed in the circumferential direction of the limit ring 11. During the process of rotating the turntable 20, the force on the moving unit in the circumferential direction is uniform, ensuring that the moving unit can move smoothly within the limit ring 11 and avoiding jamming.
[0060] According to an embodiment of the present invention, as Figure 2 shown, a sealing ring 43 is provided between the threaded portion 22 of the turntable 20 and the fixed seat 10 to seal one side of the threaded portion 22, and a sealing ring 43 is provided between the threaded portion 22 of the turntable 20 and the adjustment ring groove 13 to seal the other side of the threaded portion 22; the adjustment ring groove 13 is filled with grease. The sealing ring 43 can prevent the grease in the adjustment ring groove 13 from overflowing and also prevent external impurities from entering the adjustment ring groove 13 and affecting the rotation or movement of each component; the grease can lubricate both the inner and outer sides of the limit ring 11 through the limit grooves 14 to reduce the resistance during the sliding process of the moving unit and the rotating ring 21.
[0061] According to an embodiment of the present invention, as Figure 2 and Figure 3 shown, at least one threaded hole 24 is provided on the turntable 20, and a set screw that can tighten against the side wall 41 of the spectrometer is provided in the threaded hole 24. When the moving unit drives the camera 42 to reach the focal position, stop rotating the turntable 20 and tighten the set screw on the turntable 20 against the side wall 41 of the spectrometer housing to prevent misoperation, causing the focal length to zoom and thus affecting the test effect.
