Description

Technical Field

[0001] The utility model relates to the technical field of precision photometers, in particular to a precision photometer with a fine-tuning structure. Background Art

[0002] A photometer, also known as a spectrometer, is a scientific instrument that decomposes complex light into spectral lines. Different light sources have their own unique emission spectra, so different luminophores can be used as the instrument's light source. The instrument mainly consists of a light source, a monochromator, a sample chamber, a detector, a signal processor, and a display and storage system. Movement during use can affect detection accuracy. To prevent slippage and fine-tune the internal cuvette, most existing devices install anti-slip pads at the bottom of the photometer's support legs to increase friction between the photometer and the tabletop, allowing manual adjustment of the cuvette position.

[0003] However, research has shown that existing photometers still have the following defects:

[0004] When the existing photometer needs to adjust the position of the placement frame, it is adjusted by pulling the pulling column fixed on the placement frame. Since the pulling force is difficult to guarantee, it will cause a large error in the position of the moving support plate. Therefore, it is necessary to optimize a precision photometer with a fine-tuning structure through technological innovation and design optimization. Utility Model Content

[0005] When the existing photometer needs to adjust the position of the placement frame, it is adjusted by pulling the pulling column fixed on the placement frame. Since the pulling force is difficult to guarantee, it will cause a large error in the position of the movement of the support plate. In order to solve the above problem, the embodiment of the present application provides a precision photometer with a fine-tuning structure. The support plate can be driven to move by setting a rotating mechanism. At the same time, the diameter of the main gear is larger than the diameter of the secondary gear. Therefore, the screw rod rotates slower than the rotating rod, thereby achieving fine-tuning of the position of the support plate. The placement frame can be fixed on the support plate by aligning the insert block with the slot, which facilitates the quick disassembly and assembly of the placement frame according to the required number of placement frames, thereby improving practicality.

[0006] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0007] A precision photometer with a fine-tuning structure, comprising:

[0008] photometer;

[0009] A support plate is provided inside the photometer, and a rotating mechanism capable of driving the support plate to move is provided inside the photometer. A placement frame is plugged into the top of the support plate through a plug-in portion, and slots are provided on both sides of the placement frame.

[0010] In one possible implementation, the photometer includes a photometer body, a protective cover that can be opened and closed is hinged on the top of the photometer body, the photometer includes a photometer body, a protective cover that can be opened and closed is hinged on the top of the photometer body, support legs are fixed at the bottom of the photometer body near the four corners, and anti-slip pads are fixed at the bottom of the support legs to prevent slipping.

[0011] In one possible implementation, the moving mechanism includes a fixed block fixed at the bottom of the support plate, a threaded hole is provided on the fixed block, a screw is threadedly connected to the threaded hole, both ends of the screw are rotatably connected to the photometer body, and moving blocks are provided on both sides of the bottom of the support plate. The screw can drive the fixed block to move, and the fixed block can drive the support plate to move.

[0012] In one possible implementation, a guide hole is provided on the moving block, a guide column is provided in the guide hole, both ends of the guide column are fixedly connected to the photometer body, and the support plate drives the moving block to slide on the guide column, thereby improving the stability of the support plate during movement.

[0013] In one possible implementation, a main gear is fixed on the screw rod, a rotating rod passes through the photometer body, and a secondary gear is fixed to the end of the rotating rod facing the main gear. The rotating rod can drive the secondary gear to rotate, and the secondary gear can drive the column gear to rotate. The diameter of the main gear is larger than that of the secondary gear, so the screw rod rotates slower than the rotating rod, thereby achieving fine-tuning of the position of the support plate.

[0014] In a possible implementation, a rotating column is fixed to one end of the rotating rod away from the main gear, and the rotating column is provided with anti-slip grooves to facilitate the rotation of the rotating rod.

[0015] In a possible implementation, a circular ring is fixed to the outside of the photometer body, and the rotating column is located inside the circular ring to avoid accidental touching of the rotating column.

[0016] In one possible implementation, the plug-in portion includes a slot provided on the top of the support plate, and an insert block is fixed to the bottom of the placement frame. The insert block can be inserted into the slot, and the placement frame can be fixed to the support plate by aligning the insert block with the slot, so that the placement frame can be quickly disassembled and assembled according to the number of placement frames required.

[0017] In summary, the present invention has at least one of the following beneficial technical effects:

[0018] 1. The secondary gear is driven to rotate by the rotating column, the secondary gear drives the main gear to rotate, the main gear drives the screw to rotate, the screw can drive the fixed block to move, the fixed block can drive the support plate to move, the support plate drives the moving block to slide on the guide column to improve the stability of the support plate when moving.

[0019] 2. The placement frame can be fixed on the support plate by aligning the insert block with the slot, which makes it easy to quickly disassemble and assemble the placement frame according to the number of placement frames required, thereby improving practicality.

[0027] The following will combine the drawings in the present invention to clearly and completely describe the technical solution of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The instrument placement rack involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] This embodiment introduces a specific structure of a precision photometer with a fine-tuning structure. Figures 1-6As shown, a precision photometer with a fine-tuning structure includes:

[0029] photometer;

[0030] Among them, a support plate 6 is provided inside the photometer, and a rotating mechanism that can drive the support plate 6 to move is provided inside the photometer. A placement frame 9 is plugged into the top of the support plate 6 through a plug-in portion, and slots 8 are opened on both sides of the placement frame 9.

[0031] In addition, the photometer includes a photometer body 1, a protective cover 2 that can be opened and closed is hinged on the top of the photometer body 1, and support legs 3 are fixed at the bottom of the photometer body 1 near the four corners, and anti-slip pads are fixed at the bottom of the support legs 3 to prevent slipping.

[0032] When the position of the support plate 6 needs to be adjusted, the moving mechanism includes a fixed block 18 fixed to the bottom of the support plate 6, a threaded hole 17 is provided on the fixed block 18, a screw rod 13 is threadedly connected to the threaded hole 17, both ends of the screw rod 13 are rotatably connected to the photometer body 1, and moving blocks 12 are provided on both sides of the bottom of the support plate 6. The screw rod 13 can drive the fixed block 18 to move, and the fixed block 18 can drive the support plate 6 to move.

[0033] When the support plate 6 moves, a guide hole 11 is opened on the moving block 12, and a guide column 10 is provided in the guide hole 11. Both ends of the guide column 10 are fixedly connected to the photometer body 1. The support plate 6 drives the moving block 12 to slide on the guide column 10, thereby improving the stability of the support plate 6 when moving.

[0034] When it is necessary to drive the screw rod 13 to rotate, a main gear 14 is fixed on the screw rod 13, and a rotating rod 16 is passed through the photometer body 1. A secondary gear 15 is fixed to the end of the rotating rod 16 facing the main gear 14. The rotating rod 16 can drive the secondary gear 15 to rotate, and the secondary gear 15 can drive the column gear to rotate. The diameter of the main gear 14 is larger than that of the secondary gear 15, so the screw rod 13 rotates slower than the rotating rod 16, thereby achieving fine-tuning of the position of the support plate 6.

[0035] It is worth noting that a rotating column 5 is fixed to one end of the rotating rod 16 away from the main gear 14 , and the rotating column 5 is provided with anti-slip grooves to facilitate the rotation of the rotating rod 16 .

[0036] In addition, a circular ring 4 is fixed to the outside of the photometer body 1 , and the rotating column 5 is located inside the circular ring 4 to avoid accidental touching of the rotating column 5 .

[0037] When the placement frame 9 needs to be disassembled, the plug-in portion includes a slot 7 provided on the top of the support plate 6, and an insert block 19 is fixed to the bottom of the placement frame 9. The insert block 19 can be inserted into the slot 7. The placement frame 9 can be fixed to the support plate 6 by aligning the insert block 19 with the slot 7, which facilitates the quick disassembly and assembly of the placement frame 9 according to the number of placement frames 9 required.

[0038] The photometer body 1 is a 721 manual spectrophotometer.

[0039] When the staff needs to fine-tune the position of the support plate 6, the secondary gear 15 is driven to rotate by the rotating column 5, and the secondary gear 15 drives the main gear 14 to rotate. The main gear 14 drives the screw rod 13 to rotate, and the screw rod 13 can drive the fixed block 18 to move, and the fixed block 18 can drive the support plate 6 to move. The support plate 6 drives the moving block 12 to slide on the guide column 10, thereby improving the stability of the support plate 6 when moving. The diameter of the main gear 14 is larger than that of the secondary gear 15, so the screw rod 13 rotates slower than the rotating rod 16, thereby achieving fine-tuning of the position of the support plate 6. When it is necessary to disassemble and assemble the placement frame 9, the placement frame 9 can be fixed on the support plate 6 by aligning the insert block 19 with the slot 7, which is convenient for quick disassembly and assembly of the placement frame 9 according to the required number of placement frames 9.

[0040] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
