[0024] like Figures 1-5 As shown, a diluent quantitative preparation device includes a diluent 1. The diluent 1 draws in solvent and reagent through two hoses, thereby mixing the solvent and reagent evenly inside to form a diluent, which is then discharged through a hose on the other side. An adjustment mechanism 2 is provided on one side of the diluent 1. The adjustment mechanism 2 includes a temperature control component 3, which includes a constant temperature water bath 301. The constant temperature water bath 301 can adjust the temperature according to the different solvents, thereby avoiding the solvent from separating due to temperature changes, ensuring that the reagent and solvent are at the same temperature, accelerating the dilution rate and improving the uniformity of dilution. A placement rack 302 is connected inside the constant temperature water bath 301 via a lifting component 4.

[0025] In this embodiment, the lifting assembly 4 includes two lifting rods 401 and a sliding groove 403. The lifting rods 401 are fixedly installed on both sides of the top of the placement rack 302.

The adjusting rod 404 passes through the outer wall of the constant temperature water bath 301 and is slidably connected to the constant temperature water bath 301. The adjusting rod 404 adjusts the position of the limit block 402. A spring 405 is sleeved on the surface of the adjusting rod 404, and one end of the spring 405 is fixedly connected to one side of the limit block 402. The lifting assembly 4 can adjust the height of the placement rack 302, thereby enabling water bath heating of containers of different types and sizes.

[0026] In the embodiment, the rotating mechanism 5 is arranged between the rack 302 and the constant-temperature water bath 301, the rotating mechanism 5 comprises two placing tables 501, the two placing tables 501 are rotatably installed on the rack 302, a driven gear 502 is arranged in the placing table 501, the driven gear 502 is connected with a driving gear 503 in a meshing mode, the driving gear 503 is located in the interior of the rack 302 and is rotatably connected with the rack 302. The center of the driving gear 503 is provided with a slot 504, the rack 302 is provided with a through hole, the through hole and the slot 504 are located on the same axis, and the diameter of the through hole is greater than that of the slot 504. A rotating rod 505 is inserted into the slot 504, and a motor 506 is fixedly installed at the top end of the rotating rod 505. The motor 506 drives the rotating rod 505 to rotate, the cross section of the rotating rod 505 is a cross-shaped structure, the rotating rod 505 is connected with the slot 504 in a plug-in mode, so that the driving gear 503 can be driven to rotate, the placing table 501 can be driven to rotate through the meshing of the gears, and the rotation of the reagent is realized, so that the concentration of the reagent is balanced and adjusted.

[0027] In the embodiment, the two lifting rods 401 are provided with a plurality of right-angled triangle grooves on the opposite sides, the grooves are arranged in an array mode and are adaptively matched with the limiting blocks 402. The limiting blocks 402 limit the lifting rods 401, the right-angled triangle grooves enable the lifting rods 401 to freely ascend and are limited to descend, so that the rack 302 is prevented from being affected by gravity and the reagent is prevented from being polluted.

[0028] In the embodiment, the side of the limiting block 402 close to the sliding groove 403 is provided with a cross-shaped structure, the cross-shaped structure limits the limiting block 402 from being separated from the sliding groove 403.

[0029] In the embodiment, the bottom end of the motor 506 is fixedly installed with a rotating table 508, the output shaft of the motor 506 penetrates through the rotating table 508 and is connected with the rotating rod 505, the surface of the rotating table 508 is rotatably installed with a mounting frame 507, the mounting frame 507 is slidably installed at the top end of the constant-temperature water bath 301, the mounting frame 507 supports the motor 506, the rotating table 508 and the rotating rod 505, and the rotation of the rotating table 508 enables the angle of the rotating rod 505 to be adjusted, so that the rotating rod 505 and the slot 504 are convenient to disassemble and assemble.

[0030] It should be noted that this utility model is a device for quantitative preparation of diluent. In use, the lifting rod 401 is pulled upwards, causing the placement rack 302 to move upwards. The container containing reagents and solvents is placed on the placement platform 501. By pulling the adjusting rod 404, the adjusting rod 404 causes the limiting block 402 to move along the sliding groove 403, thereby disengaging from the lifting rod 401. This allows the placement rack 302 to be freely adjusted in height until the water level is higher than the water level of the solvent and reagents in the container. Releasing the adjusting rod 404 causes the limiting block 402 to re-engage with the lifting rod 401 under the elastic force of the spring 405, thus fixing the position of the placement rack 302.

[0031] The angle of the rotating rod 505 can be adjusted by rotating the rotating platform 508, allowing it to be inserted into the slot 504. The mounting bracket 507 is then snapped onto the top of the constant temperature water bath 301, supporting the rotating platform 508 and the motor 506. After fixing, the feed tube of the diluent 1 is added to the container, and the constant temperature water bath 301 and motor 506 are started. The constant temperature water bath 301 maintains a constant temperature, enhancing the uniformity and speed of stirring. The motor 506 drives the rotating rod 505 to rotate, and the rotating rod 505, through its insertion into the slot 504, drives the drive gear 503 to rotate. The drive gear 503, through the meshing of the gears, drives the two driven gears 502 to rotate, thereby driving the placement platform 501 to rotate. The placement platform 501 then rotates the container on it, thus improving the uniformity of the reagent's concentration. Start diluent 1. Diluent 1 draws the reagent and solvent into the diluent through a hose on one side for stirring and dilution, and then discharges the diluted liquid through a hose on the other side.
