[0029] Please refer to Figures 1 to 3The pinhole adjusting structure provided by the embodiment of the utility model mainly includes fixed seat 1, adjusting seat 2, slit sheet 3, adjusting part 4 and elastic connecting piece 5.Adjusting seat 2 is located above fixed seat 1.Slit sheet 3 is arranged on adjusting seat 2, and a pinhole 31 is formed in slit sheet 3 and penetrates through the front and back sides of slit sheet 3.Adjusting part 4 is provided with four adjusting parts 4, and the four adjusting parts 4 are respectively located on the front side, the back side, the left side and the right side of slit sheet 3.Adjusting part 4 is screwed with adjusting seat 2, one end of adjusting part 4 is located below adjusting seat 2 and is pressed on the top surface of fixed seat 1.Elastic connecting piece 5 includes connecting piece 511 and elastic part 512.Connecting piece 511 includes rod part 513 and cap part 514 which are connected, rod part 513 penetrates through adjusting seat 2 and is connected with fixed seat 1, cap part 514 is located above adjusting seat 2, elastic part 512 is sleeved on rod part 513, and the two ends of elastic part 512 are respectively in contact with cap part 514 and adjusting seat 2.
[0030] In the pinhole adjusting structure, fixed seat 1 is used for providing a supporting basis for the pinhole adjusting structure as a whole, and adjusting seat 2 is used for providing support for slit sheet 3.Adjusting part 4 is screwed with adjusting seat 2, and rotating adjusting part 4 can change the length of adjusting part 4 which is screwed out below adjusting seat 2.Because one end of adjusting part 4 which is located below adjusting seat 2 is pressed on the top surface of fixed seat 1, when adjusting part 4 is rotated to change the length of adjusting part 4 which is screwed out below adjusting seat 2, adjusting seat 2 and the side of adjusting part 4 corresponding to adjusting seat 2 can be lifted or lowered in turn.Further, because the four adjusting parts 4 are respectively located on the front side, the back side, the left side and the right side of slit sheet 3, the four adjusting parts 4 can be adjusted according to actual detection requirements, so that the height position, the left and right inclination angle and the front and back pitch angle of adjusting seat 2, slit sheet 3 on adjusting seat 2 and pinhole 31 on slit sheet 3 can be changed.
[0031] Elastic part 512 of elastic connecting piece 5 is used for providing an elastic force downward for adjusting seat 2, and the action of rotating each adjusting part 4 can make elastic part 512 of elastic connecting piece 5 be elastically deformed between cap part 514 and adjusting seat 2 when adjusting seat 2 is lifted or lowered, so that the elastic force can ensure the stability of adjusting seat 2 in the adjusting process, and adjusting seat 2, slit sheet 3 on adjusting seat 2 and pinhole 31 on slit sheet 3 can be kept at the adjusted height position, the left and right inclination angle and the front and back pitch angle after adjusting part 4 is rotated, so that the position adjustment of adjusting seat 2 has stability and reliability.Therefore, the pinhole adjusting structure can realize flexible control of the position and angle of pinhole 31 by adjusting the four adjusting parts 4 according to actual detection requirements, so that the flexibility and adaptability of the state switching of pinhole 31 are improved, and different types of slit sheet 3 do not need to be equipped, so that the maintenance and management cost can be reduced.
[0032] It is conceivable that rotating the adjusting member 4 located at the front side and the rear side of the slit sheet 3 can fine-tune the front and rear pitch angle of the pinhole 31, rotating the adjusting member 4 located at the left side and the right side of the slit sheet 3 can fine-tune the left and right inclination angle of the pinhole 31, and rotating the four adjusting members 4 and making the length of the four adjusting members 4 rotated out below the adjusting seat 2 consistent can adjust the height position of the pinhole 31.
[0033] It should be noted that since the elastic force and the force of the adjusting member 4 pushing the adjusting seat 2 upward are located at the upper and lower sides of the adjusting seat 2 respectively, the effect of balance stability is better.
[0034] In other embodiments, the elastic connecting member 5 is a component with elasticity, such as a spring or a spring sheet structure, etc. The two ends of the elastic connecting member 5 are connected with the top surface of the fixed seat 1 and the bottom surface of the adjusting seat 2 respectively. The elastic force provided by the elastic connecting member 5 for the adjusting seat 2 is downward pulling force, which is located at the same side as the force of the adjusting member 4 pushing the adjusting seat 2 upward. Compared with the above embodiment, the effect of balance stability is relatively insufficient.
[0035] In the present embodiment, the rod part 513 is connected with the fixed seat 1 by screwing.
[0036] Please refer to Figure 2 In specific embodiments, the four adjusting members 4 are a first adjusting member 41, a second adjusting member 42, a third adjusting member 43 and a fourth adjusting member 44 located at the front side, the rear side, the left side and the right side of the slit sheet 3 respectively.

The first elastic connecting member 51 and the second elastic connecting member 52 are located at the front and rear sides of the third adjusting member 43 respectively, and the third elastic connecting member 53 and the fourth elastic connecting member 54 are located at the front and rear sides of the fourth adjusting member 44 respectively.
[0037] Specifically, the first elastic connecting member 51 and the second elastic connecting member 52 cooperate to ensure the stability of the left side of the adjusting seat 2 when rotating the third adjusting member 43, the third elastic connecting member 53 and the fourth elastic connecting member 54 cooperate to ensure the stability of the right side of the adjusting seat 2 when rotating the fourth adjusting member 44, the first elastic connecting member 51 and the third elastic connecting member 53 cooperate to ensure the stability of the front side of the adjusting seat 2 when rotating the first adjusting member 41, and the second elastic connecting member 52 and the fourth elastic connecting member 54 cooperate to ensure the stability of the rear side of the adjusting seat 2 when rotating the second adjusting member 42, so as to ensure that when each adjusting member 4 is rotated, the side of the adjusting seat 2 corresponding to each adjusting member 4 can be subjected to uniform elastic force, thereby ensuring the stability of the adjusting process.
[0038] In other embodiments, the four elastic connectors 5 are respectively a first elastic connector 51 on the front side of the first adjusting member 41, a second elastic connector 52 on the back side of the first adjusting member 41, a third elastic connector 53 on the left side of the third adjusting member 43, and a fourth elastic connector 54 on the right side of the fourth adjusting member 44. When each adjusting member 4 rotates, the adjusting seat 2 on the side corresponding to each adjusting member 4 is only subjected to the elastic force of one elastic connector 5 on the side, which is more limited in stability than the above embodiment.
[0039] Referring to Figure 1 and Figure 2 In the present embodiment, the fixed seat 1 and the adjusting seat 2 each include a body 21 and two extensions 22, the body 21 is rectangular in shape, and the two extensions 22 are respectively connected to the body 21 and are respectively located on the front side and the back side of the body 21. The first adjusting member 41 and the second adjusting member 42 are respectively located on the two extensions 22. The third adjusting member 43, the fourth adjusting member 44, and the four elastic connectors 5 are all located on the body 21. The first adjusting member 41 and the second adjusting member 42 are respectively located on the two extensions 22, far from the center of the body 21, and can more accurately adjust the front-to-back pitch angle of the slit sheet 3.
[0040] In the present embodiment, the first adjusting member 41 and the second adjusting member 42 are respectively arranged on the front and back sides of the slit sheet 3 and are oppositely arranged, and the third adjusting member 43 and the fourth adjusting member 44 are respectively arranged on the left and right sides of the slit sheet 3 and are oppositely arranged. The first elastic connector 51, the second elastic connector 52, the third elastic connector 53, and the fourth elastic connector 54 are respectively arranged at the four corner positions of the rectangular body 21 of the adjusting seat 2. The overall structure of the pinhole adjusting structure is arranged in a symmetrical manner, thereby improving the stability of the overall structure.
[0041] Referring to Figure 3 In a specific embodiment, the adjusting member 4 includes an adjusting rod 411 and an adjusting cap 412 connected to one end of the adjusting rod 411, and the other end of the adjusting rod 411 has a ball structure 413. A positioning groove 11 in the shape of a hemisphere is formed on the top surface of the fixed seat 1. The adjusting seat 2 is provided with a connecting hole 23, the adjusting rod 411 is screwed with the connecting hole 23, the ball structure 413 is pressed in the positioning groove 11, and the adjusting cap 412 is located above the adjusting seat 2. The cooperation between the ball structure 413 and the positioning groove 11 can make the adjustment smoother and has the effect of limiting deviation.
[0042] It is conceivable that the rod portion 513 is screwed with the connecting hole 23, which can be that the rod portion 513 has external threads, the connecting hole 23 has internal threads, or the rod portion 513 has external threads, the connecting hole 23 is embedded with a nut, the nut has internal threads, and the rod portion 513 is screwed with the nut.
[0043] Please refer to Figures 1 to 3 In a specific embodiment, the slit sheet 3 is provided with at least two long strip-shaped pinholes 31, and each pinhole 31 is distributed in parallel and at intervals in the extension direction of the slit sheet 3. Since the pinholes 31 are distributed in parallel and at intervals in the extension direction of the slit sheet 3, adjusting the position of the slit sheet 3 can achieve simultaneous adjustment of multiple pinholes 31, thereby improving the adjustment efficiency.
[0044] In an actual use scenario, the fixed seat 1 is movably fixed in a spectrometer, and the fixed seat 1 is used to switch different pinholes 31, thereby further improving the applicability of the pinhole adjusting structure.
[0045] Although the present application has been described with reference to several exemplary embodiments, it is understood that the words that have been used are words of description and illustration, rather than words of limitation. Since the present application can be embodied in various forms without departing from the spirit or essential characteristics thereof, it is understood that the embodiments are not limited to any particular details, but are to be accorded the full scope of the appended claims, and equivalents thereof.
