Abstract
Description
Technical Field
[0001] This utility model relates to the field of experimental equipment technology, specifically to a stable base for an electrochemical titrator. Background Technology
[0002] In the field of chemical analysis, electrochemical titrators are important analytical instruments that determine the titration endpoint by measuring changes in electrode potential. They are widely used in many fields such as water quality monitoring, chemical raw material testing, and pharmaceutical component analysis. During titration, the container holding the solution to be tested needs to be placed on the titrator's base, and the stability of the base directly affects the accuracy and reliability of the titration process.
[0003] However, existing electrochemical titrator bases generally have design flaws, lacking effective measures to secure containers placed on them. In actual operation, slight touches by operators, vibrations in the laboratory environment, or even shaking of the burette during titration can cause containers to shift, shake, or even tip over. Once the container becomes unstable, it will not only cause the solution to spill and contaminate the experimental environment, but also affect the accuracy of the titration data, leading to deviations in the analytical results and requiring the experiment to be repeated, increasing experimental costs and time.
[0004] In view of the above, this application is hereby submitted. Utility Model Content
[0005] The purpose of this invention is to provide a stable base for an electrochemical titrator to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model provides a stabilizing base for an electrochemical titrator, including a titrator, a column vertically mounted on the titrator, a titration rack slidably mounted on the column, and a sliding frame slidably mounted on the column, the sliding frame being located below the titration rack. The sliding frame is provided with a clamping assembly for clamping and fixing the titration container on the titrator. The clamping assembly includes a positioning ring connected to the sliding frame, an adjusting bolt threadedly connected to the positioning ring, the adjusting bolt rotating on the positioning ring to move radially along the positioning ring, a sliding rod connected to one end of the adjusting bolt extending into the positioning ring, and an abutment head connected to one end of the sliding rod.
[0007] Furthermore, the titration holder can slide along the column axis, and the titration holder is provided with a positioning hole for inserting a burette.
[0008] Furthermore, the contact head is made of rubber and is connected to the end of the sliding rod away from the adjusting bolt.
[0009] Furthermore, the sliding frame is provided with a sliding sleeve, and the sliding frame is sleeved on the column through the sliding sleeve. A locking bolt is threaded on the outer wall of the sliding sleeve, and the sliding sleeve is fixed to the column through the locking bolt.
[0010] Furthermore, multiple sliding rods are provided, and the multiple sliding rods are equidistantly distributed along the circumference of the positioning ring. The positioning ring also has a receiving cavity inside, and a transmission gear corresponding to the number of sliding rods is rotatably installed inside the receiving cavity. The outer wall of the sliding rod is provided with tooth grooves that mesh with the transmission gears. A transmission gear ring is also rotatably installed inside the receiving cavity, and each of the transmission gears is meshed with the transmission gear ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. In this utility model, the positioning ring, adjusting bolt, and sliding rod work together to press the container tightly from multiple points around the perimeter.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-4 This utility model provides a technical solution: a stable base for an electrochemical titrator, including a titrator 1, a column 2 vertically mounted on the titrator 1, a titration rack 3 slidably mounted on the column 2, and a sliding frame 4 slidably mounted on the column 2, the sliding frame 4 being located below the titration rack 3, and a clamping assembly for clamping and fixing the titration container on the titrator 1 on the sliding frame 4, the clamping assembly including a positioning ring 5 connected to the sliding frame 4, an adjusting bolt 7 threadedly connected to the positioning ring 5, the adjusting bolt 7 rotating on the positioning ring 5 to move radially along the positioning ring 5, and a sliding rod 8 connected to one end of the adjusting bolt 7 extending into the positioning ring 5, and an abutment head 9 connected to one end of the sliding rod 8.
[0024] Specifically, the sliding frame 4 is sleeved onto the column 2 and can slide up and down along the column 2 to adjust its position. After adjusting to a suitable height, it is fixed by locking bolts. A positioning ring 5 is installed on the sliding frame 4. When the titration container is placed on the titrator 1, rotating the adjusting bolt 7 causes it to move radially along the positioning ring 5, moving the sliding rod 8 and the contact head 9 towards the container. Multiple contact heads 9 contact the outer wall of the container from different directions, achieving clamping and fixing of the container. The clamping assembly effectively fixes the titration container, preventing displacement or tipping during titration due to contact, vibration, or other factors, thus improving titration stability and data accuracy. The sliding frame 4 is adjustable up and down to accommodate titration containers of different heights, enhancing the versatility of the device. The threaded connection between the positioning ring 5 and the adjusting bolt 7 allows for precise control of the movement distance of the contact head 9 by rotating the bolt, achieving clamping and fixing of containers of different diameters.
[0025] As a technical optimization of this utility model, the titration holder 3 can slide along the axial direction of the column 2, and the titration holder 3 is provided with a positioning hole for inserting the titration test tube.
[0026] Specifically, the titration rack 3 is fitted onto the column 2 via a sliding sleeve and can slide up and down along the axis of the column 2. After adjustment to a suitable height, it is fixed. The burette is inserted into the positioning hole of the titration rack 3 to achieve positioning of the burette. The titration rack 3 can slide and adjust axially, and can adjust the position of the burette according to the height of the titration container to ensure that the burette is correctly aligned with the container, which facilitates the titration operation.
[0027] As a technical optimization of this utility model, the contact head 9 is made of rubber and is connected to the end of the sliding rod 8 away from the adjusting bolt 7.
[0028] Specifically, the rubber contact head 9 is connected to the end of the sliding rod 8. When the contact head 9 contacts the outer wall of the container, the elastic deformation of the rubber generates friction to clamp the container. The rubber material has good elasticity and anti-slip properties. When the contact head 9 contacts the outer wall of the container, it can fit tightly against the container surface while avoiding scratching the container. The elastic clamping can accommodate a certain degree of container shape error, and at the same time, the elastic buffer reduces the impact of external vibration on the container, further improving the fixing effect.
[0029] As a technical optimization of this utility model, a sliding sleeve is provided on the sliding frame 4. The sliding frame 4 is sleeved on the column 2 through the sliding sleeve. A locking bolt is threaded on the outer wall of the sliding sleeve, and the sliding sleeve is fixed on the column 2 through the locking bolt.
[0030] Specifically, the sliding frame 4 is connected to the column 2 by a sliding sleeve. The sliding sleeve can slide on the column 2. After adjusting to the appropriate position, tighten the locking bolt to make the inner wall of the sliding sleeve in close contact with the column 2, thereby fixing the sliding frame 4 to the column 2. The structure of the sliding sleeve and the locking bolt facilitates quick adjustment of the height of the sliding frame 4 to meet the fixing needs of containers of different heights.
[0031] As a technical optimization of this utility model, multiple sliding rods 8 are provided, and the multiple sliding rods 8 are distributed equidistantly along the circumference of the positioning ring 5. The positioning ring 5 also has a receiving cavity 10 inside, and a transmission gear 12 corresponding to the number of sliding rods 8 is rotatably installed inside the receiving cavity 10. The outer wall of the sliding rod 8 is provided with tooth grooves that mesh with the transmission gear 12. A transmission gear ring 11 is also rotatably installed inside the receiving cavity 10, and each transmission gear 12 is meshed with the transmission gear ring 11.
[0032] Specifically, multiple sliding rods 8 are equidistantly distributed along the circumference of the positioning ring 5. The toothed grooves on the outer wall of each sliding rod 8 mesh with the transmission gear 12, which in turn meshes with the transmission gear ring 11. When one of the adjusting bolts 7 is rotated, the transmission gear 12 is driven to rotate through the transmission structure, thereby causing the multiple sliding rods 8 to move synchronously toward or away from the center of the positioning ring 5, achieving synchronous clamping or releasing of the container. The circumferentially equidistant sliding rods 8 can evenly clamp the container from multiple directions, making the container subjected to uniform force and more stable fixation. The meshing transmission structure of the transmission gear 12 and the transmission gear ring 11 enables the synchronous movement of multiple sliding rods 8. Only one adjusting bolt 7 is needed to complete the clamping of the container, making operation more convenient and improving work efficiency.
[0033] As a technical optimization of this utility model, a mounting bracket 6 is installed on the outer wall of the positioning ring 5, and an adjusting bolt 7 is threadedly connected to the mounting bracket 6.
[0034] Specifically, the mounting bracket 6 is fixed to the outer wall of the positioning ring 5, and the adjusting bolt 7 is threaded into the threaded through hole of the mounting bracket 6. When the adjusting bolt 7 is rotated, it moves radially along the threaded through hole, causing the sliding rod 8 and the contact head 9 to move. The mounting bracket 6 provides mounting support for the adjusting bolt 7, making the connection between the adjusting bolt 7 and the positioning ring 5 more stable. By fixing the position of the adjusting bolt 7 with the mounting bracket 6, the operator can accurately control the rotation of the adjusting bolt 7, thereby precisely adjusting the position of the contact head 9 and improving clamping accuracy.
[0035] As a technical optimization of this utility model, the mounting bracket 6 is provided with a threaded through hole, and the adjusting bolt 7 is threadedly connected inside the threaded through hole.
[0036] Specifically, the threaded through hole on the mounting bracket 6 and the adjusting bolt 7 form a threaded connection pair. When the adjusting bolt 7 is rotated, the adjusting bolt 7 moves axially within the threaded through hole to achieve radial displacement. The threaded connection between the threaded through hole and the adjusting bolt 7 has good self-locking properties, which can ensure that the adjusting bolt 7 will not loosen on its own after being adjusted to the appropriate position, ensuring that the clamping force of the contact head 9 on the container is stable and preventing the container from shaking due to the loosening of the bolt.
[0037] As a technical optimization of this utility model, multiple toothed grooves are provided on the side wall of the sliding rod 8, and the multiple toothed grooves are continuously arranged along the length direction of the sliding rod 8.
[0038] Specifically, multiple toothed grooves continuously arranged on the side wall of the sliding rod 8 mesh with the transmission gear 12. When the transmission gear 12 rotates, it drives the sliding rod 8 to move radially along the positioning ring 5 through the toothed grooves. Since the toothed grooves are continuously arranged, the sliding rod 8 can move continuously and smoothly.
[0039] Working principle: The column 2 on the titrator 1 serves as the main support, and simultaneously slides to connect the titration rack 3 and the sliding rack 4. The titration rack 3 can slide up and down along the column 2 to position the burette. The sliding rack 4 is located below the titration rack 3 and is sleeved on the column 2. Its position can be fixed by locking bolts, which facilitates the adjustment of the vertical position of the clamping components according to the height of the titration container.
[0040] The positioning ring 5 is fixed to the sliding frame 4 by the mounting bracket 6. The adjusting bolt 7 is threadedly connected to the mounting bracket 6. When the adjusting bolt 7 is rotated, it moves radially along the positioning ring 5, pushing the sliding rod 8 to move towards the center of the positioning ring 5, so that the contact head 9 presses against the outer wall of the titration container. Multiple sliding rods 8 mesh with the transmission gear ring 11 through the transmission gear 12. When the adjusting bolt 7 is rotated, it can drive the transmission gear ring 11 to rotate, so that the sliding rods 8 move towards the center synchronously, so as to achieve uniform clamping of the container and improve the fixing efficiency.
[0041] Both the sliding frame 4 and the titration frame 3 can slide along the column 2 and be fixed with locking bolts. This allows them to adapt to different heights of titration containers and burettes, ensuring the relative position of the container and burette remains stable during titration.
