Description

Technical Field

[0001] This utility model relates to the field of detection technology, and in particular to a novel detection titration device. Background Technology

[0002] In laboratory testing, burettes are often used to precisely add a certain amount of reagent to a beaker containing a solution for chemical reaction or quantitative analysis. In many experiments, multiple beakers may contain different test solutions for reaction with different test liquids.

[0003] In current titration devices, after the reaction between the titrant and the analyte is complete, the beaker is usually removed from the clamping device and the clamping is released. Then, another beaker is used for the next titration. This process results in low work efficiency because the beaker needs to be replaced and the device needs to be adjusted after each titration, which increases the time cost and complexity of the operation.

[0004] Therefore, we propose a novel detection titration device. Summary of the Invention

[0005] The present invention aims to solve the technical problems existing in the prior art and provide a novel detection titration device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel titration device, comprising a worktable body, a turntable provided on the top wall of the worktable body, a loading tray placed on the turntable, a plurality of placement slots annularly formed on the top wall of the loading tray, fixing frames fixedly installed on the top walls of the turntable on both sides of the loading tray, fixing components for fixing the loading tray respectively provided on the two fixing frames, the fixing components including two first guide slide rods, two pull blocks, two springs and two first clamping blocks, a rack fixedly installed on the outer wall of the turntable, a mounting box fixedly installed on the top wall of the front end of the worktable body, a transmission mechanism for rotating the turntable provided on the mounting box, the transmission mechanism including a rotating rod, a gear and a handwheel, a placement hole provided on the top wall of the bracket, and two second clamping blocks for clamping the burette provided inside the bracket.

[0011] This invention provides a novel detection titration device. It has the following beneficial effects:

[0012] 1. This novel titration device involves placing a beaker in the placement slot and simultaneously pulling two levers. These levers, via a first guide rod, move two first clamping blocks away from each other, compressing two springs. The loading tray is then placed between the two clamping blocks, which are released. The springs then return, clamping the loading tray in place. The operator can then perform titration on any beaker. Turning the handwheel rotates the rotating rod and gear. The gear meshes with the rack, causing the turntable and loading tray to rotate, allowing the titrant inside the burette to be dispensed into beakers containing different test solutions. After titration, multiple beakers can be removed as a whole via the loading tray, making the process more efficient and convenient.

Fixing brackets 18 are fixedly installed on the top walls of the turntable 14 on both sides of the loading tray 16. Each fixing bracket 18 has a fixing component for fixing the loading tray 16. The fixing component includes two first guide rods 19, two pull blocks 20, two springs 21, and two first clamping blocks 22. A rack 15 is fixedly installed on the outer wall of the turntable 14, and a mounting box 23 is fixedly installed on the top wall of the front end of the workbench body 10. The box 23 is equipped with a transmission mechanism for rotating the turntable 14. The transmission mechanism includes a rotating rod 24, a gear 25, and a handwheel 26. A placement hole 27 is provided on the top wall of the support 11. Two second clamping blocks 28 for holding the burette are provided inside the support 11. An annular groove 12 is provided on the top wall of the worktable body 10. A sliding ring 13 is slidably disposed within the annular groove 12. The top wall of the sliding ring 13 is fixedly installed on the bottom wall of the turntable 14. The first clamping block 22 has an arc-shaped structure. Two first clamping blocks 22 are arranged opposite each other. The opposite ends of two first guide rods 19 are respectively fixedly connected to the two first clamping blocks 22. The ends of the sliding rods 19 that are far apart from each other pass through the fixing brackets 18 and are fixedly connected to the side walls of the two pull blocks 20 that are close to each other. The two first guide sliding rods 19 are slidably connected to the two fixing brackets 18 respectively. Springs 21 are respectively sleeved on the outer walls of the two first guide sliding rods 19 near the two first clamping blocks 22. The bottom end of the rotating rod 24 is rotatably connected to the top wall of the workbench body 10. The top end of the rotating rod 24 passes through the mounting box 23 and is fixedly connected to the bottom wall of the handwheel 26. The gear 25 is fixedly sleeved on the outer wall of the rotating rod 24 and the gear 25 is meshed with the rack 15. The two second clamping blocks 28 have an arc-shaped structure, with the second clamping block 28 on the right end being far away from the left end. A cylinder is fixedly connected to one side wall of the second clamping block 28, and the other end of the cylinder is fixedly connected to the inner wall of the placement hole 27. A threaded handle 29 is rotatably connected to the wall of the second clamping block 28 on the left side away from the center of the placement hole 27. The end of the threaded handle 29 away from the center of the placement hole 27 passes through the bracket 11 and is threadedly connected to the bracket 11.

[0023] The working principle of this utility model is as follows: In use, the burette is placed into the placement hole 27. Then, the threaded lever 29 is rotated. Under the limiting action of the two second guide slides 30, the threaded lever 29 drives the left second clamping block 28 closer to the burette and fixes it. Then, the beaker is placed into the placement slot 17. Simultaneously, the operator pulls the two pull blocks 20. The two pull blocks 20, through the two first guide slides 19, drive the two first clamping blocks 22 away from each other and compress the two springs 21. Finally, the loading tray 16 is placed between the two first clamping blocks 22 and then released. Two first clamping blocks 22 are opened, and under the action of the rebound force of two springs 21, the two first clamping blocks 22 are driven to clamp and fix the loading tray 16. Then, the staff can perform titration test from any beaker. By turning the handwheel 26, the handwheel 26 drives the rotating rod 24 and gear 25 to rotate. Since the gear 25 meshes with the rack 15, it drives the turntable 14 and loading tray 16 to rotate, so that the titrating reagent inside the burette can be dripped into the beakers of different test solutions. After titration, multiple beakers can be directly taken out as a whole through the loading tray 16, which is more efficient and convenient.
