Description

Technical Field

[0001] This utility model belongs to the field of pharmaceutical testing technology, and in particular relates to an analytical titration device for pharmaceutical testing. Background Technology

[0002] Titration analysis is a common method for drug testing. In titration, a standard solution is placed in a burette and then added dropwise to the solution to be tested. The results are calculated and analyzed based on the amount of standard solution added and the amount of solution to be tested.

[0003] However, in existing titration apparatuses, the mixing between the standard solution and the test solution is often insufficient after titration. Operators need to manually shake the container to accelerate the chemical reaction. While this step seems simple, it becomes a significant burden for operators over time. The frequent and prolonged shaking can easily cause arm pain, undoubtedly increasing their workload. Therefore, it is necessary to provide a new analytical titration apparatus for pharmaceutical testing to solve these problems. Summary of the Invention

[0004] This invention provides an analytical titration device for pharmaceutical testing, aiming to solve the problem mentioned in the background art that the operation of existing titration devices requires operators to frequently and for long periods of time to pick up and shake the container, resulting in high labor intensity.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model provides an analytical titration device for pharmaceutical testing, such as... Figure 1-4 As shown, the analytical titration apparatus for pharmaceutical testing includes: a base plate 1, a vertical plate 2 fixedly mounted on the top of the base plate 1, a mounting groove on the vertical plate 2, a first lead screw 3 rotatably mounted on the inner wall of the mounting groove, the top end of the first lead screw 3 extending to the outside of the vertical plate 2; a connecting block 4 threaded onto the first lead screw 3, a positioning plate 5 welded onto the connecting block 4, a mounting hole on the positioning plate 5, and a burette 6 for pharmaceutical testing disposed inside the mounting hole; a clamping mechanism mounted on the positioning plate 5 for fixing the burette 6; and a shaking mechanism mounted on the base plate 1 for shaking the container.

[0022] In this embodiment, when using this device for drug testing, the burette 6 containing the standard solution is first fixed in the mounting hole using a clamping mechanism. After fixing, the height of the burette 6 is adjusted according to the required container height. During adjustment, the first lead screw 3 is manually rotated, which causes the connecting block 4 to move vertically. The connecting block 4 then causes the positioning plate 5 to move vertically, which in turn causes the clamping mechanism and the burette 6 to move vertically. Thus, the burette 6 can be raised or lowered to a suitable operating height according to the container height. After adjustment, a shaking mechanism is then used. The container containing the test solution is fixed below the burette 6. After fixing, a portion of the standard solution in the burette 6 can be dripped into the container below according to the test requirements. The burette 6 is a mature existing technology, and its principle will not be described. After titration, the container can be shaken left and right using a shaking mechanism so that the standard solution comes into contact with the test solution in the container, which can accelerate the chemical reaction without the need for manual operation. In this way, the labor intensity of operators can be greatly reduced during long-term drug testing work, and it will not cause sore arms of operators.

[0023] In a further preferred embodiment of the present invention, the clamping mechanism includes: a second lead screw 19 threadedly mounted on the positioning plate 5, one end of the second lead screw 19 extending into the interior of the mounting hole, a clamping block 20 rotatably mounted on the second lead screw 19, a sliding rod 21 fixedly mounted on the clamping block 20, the sliding rod 21 being slidably connected to the inner wall of the mounting hole; a first anti-slip pad 22 fixedly mounted on the inner wall of the mounting hole; and a second anti-slip pad 23 fixedly mounted on the clamping block 20.

[0024] In this embodiment, the clamping mechanism is used to fix the burette 6 and can also contact the burette 6. When releasing, the second lead screw 19 is manually rotated, which will drive the clamping block 20 to move. At this time, the slide rod 21 connected to the clamping block 20 will also slide on the inner wall of the mounting hole. When the second anti-slip pad 23 on the clamping block 20 leaves the burette 6, the operator can take the burette 6 out of the mounting hole. By rotating the second lead screw 19 in the opposite direction, the burette 6 placed in the mounting hole can be clamped and fixed. The operation is relatively simple and can facilitate the operator to disassemble and assemble the burette 6.

[0025] In a further preferred embodiment of this utility model, the shaking mechanism includes: two support blocks 7 fixedly installed on the top of the base plate 1, each of the two support blocks 7 having a rectangular rod 8 slidably installed on it, and each of the two rectangular rods 8 having a spring 9 slidably sleeved on it; two pressure plates 10 respectively welded to one end of each of the two rectangular rods 8 close to each other; a housing 11 fixedly installed on the two pressure plates 10, the top of the housing 11 having two strip holes; a rotating shaft 12 rotatably installed on the base plate 1; a motor 13 fixedly installed on the bottom of the base plate 1, the output shaft of the motor 13 being fixedly connected to the bottom end of the rotating shaft 12; a cam 14 fixedly installed on the rotating shaft 12, the cam 14 contacting the two pressure plates 10; a bidirectional screw 15 rotatably installed on the housing 11, the bidirectional screw 15 having two sliders 16 threadedly installed on it, each of the two sliders 16 having a support plate 17 fixedly installed on it, the two support plates 17 being slidably connected to the inner walls of the two strip holes respectively; and two clamping plates 18 respectively welded to the two support plates 17 for clamping containers.

[0026] In this embodiment, the shaking mechanism is used to shake the container and also to fix it. When fixing the container, first place the container containing the solution to be tested on top of the housing 11, then manually rotate the bidirectional screw 15. The bidirectional screw 15 will drive the two sliders 16 to move closer together. The two sliders 16 will drive the two support plates 17 to slide on the inner walls of the two slots. The two support plates 17 will drive the two clamping plates 18 to move closer together until the two clamping plates 18 tightly clamp the container. The fixing is relatively simple. When the burette 6 titrates the standard solution into the container and it is necessary to shake the container, start the motor 1. 3 drives the cam 14 to rotate. When the protruding part of the cam 14 contacts the pressure plate 10, the pressure plate 10 will drive the housing 11 to move to one side. At this time, the rectangular rod 8 welded to the pressure plate 10 will also slide on the support block 7, and the pressure plate 10 will squeeze the spring 9. When the protruding part of the cam 14 leaves the pressure plate 10, the spring 9 will use its elasticity to make the pressure plate 10 move in the opposite direction, causing the housing 11 to move in the opposite direction. Thus, with the continuous rotation of the cam 14, the container can be continuously shaken, so that the test solution and the standard solution in the container can be fully mixed, which can accelerate the chemical reaction without the need for manual operation.

[0027] In a further preferred embodiment of this utility model, a limiting rod is fixedly installed on the inner wall of the mounting groove, and the limiting rod is slidably connected to the connecting block 4.

[0028] In this embodiment, the use of a limiting rod ensures that the connecting block 4 remains stable during vertical movement and does not experience any offset issues.

[0029] In a further preferred embodiment of the present invention, a plurality of bases are fixedly installed on the bottom of the base plate 1, and a rubber pad is fixedly installed on the bottom of each of the plurality of bases.

[0030] In this embodiment, by using multiple bases and multiple rubber pads, the base plate 1 can be supported at a suitable height to prevent the motor 13 from contacting the table where the device is placed.

[0031] In a further preferred embodiment of the present invention, a handwheel is fixedly installed at the top end of the first lead screw 3, and a first knob is fixedly installed at one end of the second lead screw 19.

[0032] In this embodiment, the first lead screw 3 can be easily rotated by hand via the handwheel, and the second lead screw 19 can be easily rotated by hand via the first knob.

[0033] In a further preferred embodiment of this utility model, a second knob is fixedly installed at both ends of the bidirectional screw 15, and both clamping plates 18 are set in an arc shape.

[0034] In this embodiment, the two second knobs allow personnel to easily rotate the bidirectional screw 15 by hand, and by setting the two clamping plates 18 into an arc shape, the clamping effect of the two clamping plates 18 on the container can be effectively improved.

[0035] In summary, compared with related technologies, this solution, through the use of a clamping mechanism, allows operators to easily assemble and disassemble the burette 6 in the mounting hole, facilitating its removal and replacement. The shaking mechanism not only secures the container but also shakes it, ensuring thorough mixing of the test solution and standard solution after titration of the standard solution from the burette 6 into the container. This accelerates the chemical reaction without manual intervention, significantly reducing the workload and preventing arm pain during prolonged drug testing. Furthermore, the first lead screw 3 drives the connecting block 4 vertically, which in turn moves the positioning plate 5 vertically. The positioning plate 5 then moves the clamping mechanism and the burette 6 vertically, allowing the operator to adjust the burette 6 to a suitable height based on the container's height.

[0036] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
