Description

Technical Field

[0001] This utility model belongs to the field of experimental equipment technology, specifically relating to a special support for calcium content titration. Background Technology

[0002] The primary purpose of calcium titration testing is to accurately measure the calcium content in a sample. The purpose of calcium titration includes determining the calcium content, which is of great significance in the fields of food, medicine, geology, and minerals. It provides nutritional information for food, ensures the quality of pharmaceuticals, and assesses the value of ores. It is also an important means of quality control, ensuring product performance and quality in chemical production and building materials industries. Furthermore, in the field of chemical research, it helps to understand the composition of compounds and study chemical reactions, tracking changes in calcium during reactions and providing a basis for optimizing reaction conditions.

[0003] Most existing calcium content titration tests directly use a titration rack to titrate the calcium content in the sample. While convenient, the endpoint needs to be determined based on the color change of the calcium content in the sample, requiring external lighting. However, since the angle of illumination and sensitivity to color vary from person to person, errors can occur, and the efficiency is low. Furthermore, the weight of the sample in the reagent bottle needs to be recorded before and after the test to calculate the calcium content. This is tedious, and the recording devices are often scattered, making it inconvenient to use. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing calcium content titration tests require judging the titration endpoint based on the color change of the calcium content in the titrated sample. Since the lighting conditions vary from person to person each time, there is a certain degree of error in the test. Furthermore, the weight of the sample in the reagent bottle needs to be recorded before and after the test. Since most of the recording devices are placed in a relatively scattered manner, it is inconvenient to use.

[0005] To solve the above-mentioned technical problems, the present invention provides a special support for calcium content titration, including a base, a reagent bottle, and a burette. A control panel is provided on one side of the base, and a placement platform is provided above the base. A base plate is placed above the placement platform through a groove, and the reagent bottle is placed on the base plate. An electronic scale is provided below the placement platform on the base plate. A vertical rod is provided on the side of the placement platform away from the control panel, and an adjustment plate is provided on one side of the vertical rod. A Z-shaped adjustment frame is slidably connected to the adjustment plate, and a light is rotatably connected to one end of the adjustment frame through a ball joint. A support rod is slidably connected to the outside of the vertical rod through an adjustment ring, and a movable gripper is slidably connected to the upper part of the support rod. The burette is clamped on the movable gripper.

[0006] Furthermore, the control panel includes a control screen and multiple control buttons. The control panel is electrically connected to a control module and a power module inside the base. The power module is located on one side of the base and has a power cord. The control module is electrically connected to a lighting lamp and an electronic scale.

[0007] Furthermore, the height of the adjusting plate is less than the height of the upright, and the adjusting plate is provided with a longitudinally arranged fixing groove. The adjusting frame is located at the fixing groove and is fixedly connected to the adjusting plate by a positioning bolt passing through the fixing groove.

[0008] Furthermore, the spherical universal joint is located in the middle position on one side of the upright.

[0009] Furthermore, the adjusting ring is U-shaped in shape, and fastening bolts are provided at the connection points of the U-shaped structure.

[0010] Furthermore, the support rod is eccentrically positioned on the side of the adjusting ring away from the adjusting plate.

[0011] Furthermore, the movable gripper is a U-shaped structure composed of a movable plate and an L-shaped positioning plate. The connection between the movable plate and the positioning plate is staggered, and one side of the positioning plate is fixedly connected to the staggered part of the movable plate by clamping bolts. The positioning plate is located behind the U-shaped structure of the movable gripper and is slidably connected to the two support rods.

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] 1. This support has a base plate at the bottom of the reagent bottle to block light from the bottom of the bottle, making it easier to observe the color change of the sample. At the same time, the adjustable frame and light lamp on one side can illuminate the inside of the reagent bottle from a fixed angle, which can ensure the same test conditions for different batches, reduce test errors, and improve work efficiency.

[0014] 2. This stand features an electronic scale mounted on the bottom of the base plate, making it convenient and quick to record the weight of the samples inside the reagent bottles without needing to find an external recording device. Attached Figure Description
