[0020] When the cuvette is placed, the placement groove 23 and the fixing groove 24 are set, and the size of the placement groove 23 is larger than that of the fixing groove 24. When placing the cuvette, the user can easily place the cuvette in the placement groove 23 to improve the convenience of placing the cuvette; after the cuvette is placed, the cuvette is fixed by the clamping mechanism and the fixing groove 24; the intermittent rotation mechanism drives the rotating seat 2 to rotate along the base 1, so that the rotating seat 2 drives the cuvette in the placement seat 4 to correspond to the full-spectrum photoelectric sensor 6 described below in turn, and then detects the solution in the cuvette; in addition, the placement seat 4 is detachably connected to the rotating seat 2 through the placement hole and the connecting mechanism, so that when the placement seat 4 becomes dirty after long-term use, it can be disassembled and carefully cleaned to improve the neatness of the present application.

[0021] Furthermore, if Figure 2 As shown, the base 1 is provided with a bracket 3, and the bracket 3 is provided with a full-spectrum photoelectric sensor 6; a support plate 10 is fixedly connected inside the base 1, and a spectrum scanner 13 corresponding to the full-spectrum photoelectric sensor 6 is fixedly connected to the support plate 10, and the placement seat 4 and the rotating seat 2 are both provided with through holes 25 corresponding to the full-spectrum photoelectric sensor 6 and the spectrum scanner 13; a plurality of mounting columns 11 are fixedly connected to the support plate 10, and a plurality of mounting bolts threadedly connected to the plurality of mounting columns 11 are passed through the base 1.

[0022] When the cuvette is testing, the detection light source of the spectral scanner 13 passes through the cuvette through the perforation 25 to reach the full-spectrum photoelectric sensor 6. The changes in monochromatic light from 200nm to 1100nm can be analyzed in the full-spectrum photoelectric sensor 6, which basically covers all commonly used test wavelengths. In addition, the support plate 10 and the base 1 are detachably connected through the mounting column 11 and the mounting bolts.

[0023] Furthermore, if Figure 3 and Figure 5 As shown, the clamping mechanism includes a guide block 18 fixedly connected to the rotating seat 2, and the guide block 18 has a plurality of spline grooves evenly distributed along the circumference; a plurality of the spline grooves are slidably connected to guide spline shafts 16, and a plurality of the guide spline shafts 16 are fixedly connected to chucks 17 respectively arranged in a plurality of the accommodating grooves; a fixed disk 14 is fixedly connected to the support plate 10, and a cam groove 15 is provided on the fixed disk 14, and a plurality of the guide spline shafts 16 are rotatably connected to rollers 20 cooperating with the cam groove 15; a plurality of connecting columns are fixedly connected to the fixed disk 14, and a plurality of connecting bolts threadedly connected to the plurality of the connecting columns are passed through the support plate 10.

[0025] Furthermore, the placement seat 4 is provided with a separation hole 27 that cooperates with the guide spline shaft 16 and the chuck 17. The separation hole 27 and the surface of the placement seat 4 are transitioned by a circular arc, and the surfaces of the chuck 17 are transitioned by a circular arc. The placement seat 4 is also provided with a hidden groove 26 that cooperates with the chuck 17.

[0026] By setting the separation hole 27, the separation hole 27 on the placement seat 4 can be skipped by the chuck 17 and the guide spline shaft 16 during the installation and removal of the placement seat 4; the arc is set to make the installation of the placement seat 4 more convenient; in addition, by setting the hidden groove 26, the chuck 17 can be moved into the hidden groove 26 after being released from the cuvette, so as to avoid the chuck 17 being in the placement groove 23 and affecting the user's placement of the cuvette in the placement groove 23, thereby improving the convenience of placing the cuvette of the present application.

[0027] Furthermore, if Fig.11 As shown, the intermittent rotation mechanism includes a motor 8 fixedly connected to the support plate 10, a lever 31 is fixedly connected to the output end of the motor 8, and a groove wheel 29 corresponding to the lever 31 is detachably connected to the rotating seat 2; the lever 31 is coaxially fixedly connected to the limit plate 30, and the groove wheel 29 is provided with a limit groove that cooperates with the limit plate 30.

[0028] When the intermittent rotation mechanism is in use, the motor 8 is started, the motor 8 drives the lever 31 to rotate, and the lever 31 drives the groove wheel 29 to rotate intermittently; the groove wheel 29 is limited by the cooperation of the limiting plate 30 and the limiting groove to improve the stability of the groove wheel 29.

[0029] Furthermore, the groove wheel 29 is coaxially fixed with a connecting spline shaft 28, and a spline cylinder 21 that cooperates with the connecting spline shaft 28 is fixed on the rotating seat 2; a fixing bolt 5 corresponding to the spline shaft is passed through the rotating seat 2, and a threaded hole that cooperates with the fixing bolt 5 is provided on the connecting spline shaft 28; by cooperating with the connecting spline shaft 28, the spline cylinder 21, the fixing bolt 5, and the threaded hole, the rotating seat 2 and the groove wheel 29 are detachably connected, so that the present application is convenient for cleaning the inside of the rotating seat 2, thereby improving the convenience of the present application.

[0030] Furthermore, if Figure 4 , 7 As shown in , 8, 9, and 10, the connecting mechanism includes an annular slide rail 12 fixedly connected to the support plate 10, and fan-shaped notches are provided on the annular slide rail 12 and the support plate 10. A fan-shaped slide rail 33 that can be raised and lowered and cooperates with the fan-shaped notch of the annular slide rail 12 is provided in the base 1, and a slider 19 that cooperates with the annular slide rail 12 and the fan-shaped slide rail 33 is fixedly connected to the placement seat 4.

[0031] When the connecting mechanism is in use, when the placement seat 4 is installed, the fan-shaped slide rail 33 is lowered and separated from the annular slide rail 12; the placement seat 4 is placed in the placement hole, and at this time, under the action of gravity, the slider 19 is placed on the annular slide rail 12; the rotating seat 2 is intermittently rotated, and the rotating seat 2 drives the placement seat 4 on the placement hole to move along a circle until the slider 19 corresponds to the fan-shaped notch, and under the action of gravity, the slider 19 is aligned with the annular slide rail 12 when the placement seat 4 descends, and during the rotation of the rotating seat 2, the slider 19 slides onto the annular slide rail 12, thereby realizing the installation of the placement seat 4; when the placement seat 4 is disassembled, when the slider 19 on the placement seat 4 rotates with the rotating seat 2 to correspond to the fan-shaped notch, the placement seat 4 can be removed to improve the convenience of this application.

[0032] To summarize, the placement seat 4 is fixed by cooperating with the annular slide rail 12, the fan-shaped slide rail 33, the fan-shaped notch, and the slider 19. By changing the matching relationship between the fan-shaped slide rail 33 and the annular slide rail 12, all the placement seats 4 on the rotating seat 2 can be installed and disassembled in turn under the intermittent rotation of the rotating seat 2, so as to improve the convenience of the present application.

[0033] Furthermore, a first telescopic rod 7 is fixedly connected to the base 1, and a matching block 35 is fixedly connected to the telescopic end of the first telescopic rod 7; a flat plate 40 fixed to the fan-shaped slide rail 33 is fixedly connected to the matching block 35, and a limit block 34 corresponding to the flat plate 40 is fixedly connected to the support plate 10; an active rack 36 is fixedly connected to the matching block 35, and a gear 37 meshing with the active rack 36 is rotatably connected to the base 1; a push plate 39 is slidably connected to the matching block 35, and a driven rack 38 meshing with the gear 37 is fixedly connected to the push plate 39, and the driven rack 38 is symmetrically arranged with the active rack 36.

[0034] The first telescopic rod 7 drives the matching block 35 to rise and fall, and the matching block 35 drives the fan-shaped slide rail 33 to rise and fall through the flat plate 40, thereby realizing the matching and separation of the fan-shaped slide rail 33 and the annular slide rail 12; in addition, during the disassembly process of the placement seat 4, at this time, the fan-shaped slide rail 33 has been lowered to the bottom of the slider 19 under the action of the first telescopic rod 7, and during the descending process of the matching block 35, the matching block 35 drives the active rack 36 to move, and the active rack 36 drives the gear 37 to rotate, and the gear 37 drives the push plate 39 to rise through the driven rack 38; continue to retract the first telescopic rod 7, that is, the matching block 35 continues to decline, and the matching block 35 drives the push plate 39 to rise through the active rack 36, the gear 37, and the driven rack 38, and the push plate 39 pushes the placement seat 4 to rise, so as to facilitate the user to take out the placement seat 4 through the placement hole, thereby improving the convenience of disassembly of the placement seat 4.

[0035] Furthermore, a second telescopic rod 9 is fixedly connected to the base 1, and a movable plate 32 cooperating with the placement seat 4 is fixedly connected to the telescopic end of the second telescopic rod 9; during the installation of the placement seat 4, multiple placement seats 4 are placed in corresponding placement holes respectively. Before the placement seat 4 rotates to the fan-shaped notch position with the rotating seat 2, the second telescopic rod 9 is extended, and the second telescopic rod 9 drives the placement seat 4 to move up and down through the movable plate 32, which can effectively avoid the placement seat 4 and the placement hole from getting stuck, so as to ensure that when the placement seat 4 rotates to the fan-shaped notch position, the slider 19 can be aligned with the annular slide rail 12 under the action of gravity, thereby improving the convenience of the present application.

[0036] like Figure 1-11 As shown, the working process of the present invention is explained in detail below.

[0037] When the present invention is in use, the size of the placement groove 23 is larger than that of the fixed groove 24 through the arrangement of the placement groove 23 and the fixed groove 24, so that the user can easily place the cuvette in the placement groove 23 when placing the cuvette; after the cuvette is placed, the motor 8 is started, the motor 8 drives the lever 31 to rotate, the lever 31 drives the groove wheel 29 to rotate intermittently, and the groove wheel 29 drives the rotating seat 2 to rotate; the rotating seat 2 drives the guide block 18 and the placement seat 4 to rotate, and the guide block 18 drives the chuck 17 to rotate synchronously through the guide spline shaft 16; the guide spline shaft 16 drives the roller 20 to slide in the cam groove 15, and under the action of the cam groove 15 and the roller 20, the guide spline shaft 16 slides along the guide block 18, thereby driving the chuck 17 and the fixed groove 24 to cooperate to clamp the cuvette.

[0038] At the same time, during the rotation of the rotating seat 2, the rotating seat 2 drives the placement seat 4 on which the cuvette has been placed to rotate to a position aligned with the full-spectrum photoelectric sensor 6, so that the detection light source of the spectrum scanner 13 passes through the cuvette through the perforation 25 to reach the full-spectrum photoelectric sensor 6. The changes in monochromatic light of 200nm to 1100nm can be analyzed in the full-spectrum photoelectric sensor 6, which basically covers all commonly used inspection wavelengths; in addition, the support plate 10 and the base 1 are detachably connected through the mounting column 11 and the mounting bolts.

[0039] When the placing seat 4 is installed, the first telescopic rod 7 is started, the first telescopic rod 7 drives the matching block 35 to descend, and the matching block 35 drives the fan-shaped slide rail 33 to descend through the flat plate 40, so that the fan-shaped slide rail 33 descends to the bottom of the slider 19; the placing seat 4 is placed in the placing hole. At this time, under the action of gravity, the slider 19 is placed on the annular slide rail 12; the rotating seat 2 is rotated intermittently, and before the placing seat 4 rotates to the fan-shaped notch position with the rotating seat 2, the second telescopic rod 9 is extended, and the second telescopic rod 9 drives the placing seat 4 to move up and down through the movable plate 32, which can effectively avoid the placing seat 4 and the placing hole from getting stuck; when the rotating seat 2 drives the placing seat 4 on the placing hole to move in a circle until the slider 19 corresponds to the fan-shaped notch, under the action of gravity, the slider 19 is aligned with the annular slide rail 12 when the placing seat 4 descends, and during the rotation process of the rotating seat 2, the slider 19 slides onto the annular slide rail 12, thereby realizing the installation of the placing seat 4.

[0040] When the placement seat 4 is disassembled, the first telescopic rod 7 is retracted, and the first telescopic rod 7 drives the fan-shaped slide rail 33 to descend; at the same time, during the descent of the matching block 35, the matching block 35 drives the active rack 36 to move, and the active rack 36 drives the gear 37 to rotate, and the gear 37 drives the push plate 39 to rise through the driven rack 38; the first telescopic rod 7 continues to be retracted, that is, the matching block 35 continues to descend, and the matching block 35 drives the push plate 39 to rise through the active rack 36, the gear 37, and the driven rack 38, and the push plate 39 pushes the placement seat 4 to rise, so as to facilitate the user to take out the placement seat 4 through the placement hole, thereby improving the convenience of disassembling the placement seat 4.

[0041] Compared with the prior art, the advantages and beneficial effects of the present invention are: 1. When the present invention is in use, the clamping mechanism that can fix a plurality of cuvettes on the rotating seat 2 is formed by matching the chuck 17, the guide spline shaft 16, the guide block 18, the fixed plate 14, and the cam groove 15, so that the number of parts of the clamping mechanism is greatly reduced, and the clamping mechanism fixes the cuvettes as the rotating seat 2 rotates, which not only makes the clamping mechanism and the rotation of the rotating seat 2 linked to improve the convenience of operation of the present application; but also makes it unnecessary to set up a corresponding driving unit for the clamping mechanism, which can effectively reduce the production cost of the present application.

[0042] 2. When the present invention is in use, the placement seat 4 is detachably connected to the rotating seat 2 through the placement hole and the connecting mechanism, so that when the placement seat 4 becomes dirty after long-term use, it can be disassembled and carefully cleaned to improve the neatness of the present application; in addition, the placement seat 4 is fixed by matching the annular slide rail 12, the fan-shaped slide rail 33, the fan-shaped notch, and the slider 19. By changing the matching relationship between the fan-shaped slide rail 33 and the annular slide rail 12, all the placement seats 4 on the rotating seat 2 can be installed and disassembled in turn under the intermittent rotation of the rotating seat 2 to improve the convenience of the present application.
