Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of experimental devices, and in particular to a titration stage that is easy to observe. Background Technology
[0002] Titration is a quantitative analysis method in chemical experiments. It determines the content of a certain solute by the quantitative reaction of two solutions and indicates the titration endpoint by the color change of an indicator.
[0003] Existing titration stands, such as the one disclosed in utility model patent application number 201720535488.7, which facilitates observation, mainly include a base. An iron cover plate and a white plastic plate are mounted on the upper surface of the base, with the bottom surface of the iron cover plate contacting the upper surface of the white plastic plate. A column is mounted in the middle of the upper surface of the base, and a butterfly clip is mounted on the column. A slot is provided on the upper surface of the base. In use, the white plastic plate is used instead of white paper for comparative observation. The iron cover plate protects the white plastic plate and does not interfere with other experiments. The friction between the adjusting bolt and the column fixes the position of the butterfly clip, thus accommodating the use of different burettes.
[0004] However, most existing titration stages are inconvenient to observe, and it is easy to get confused when comparing them with colorimetric plates. Moreover, they need to be shaken manually after titration, which makes it difficult to ensure uniformity and is very troublesome.
[0005] In view of the problems existing in the above-mentioned prior art, it is necessary to study and design a titration stage that is easy to observe, so as to overcome the problems existing in the prior art. Summary of the Invention
[0006] To solve the above-mentioned technical problems, this utility model provides a titration stage that not only drives the container to rotate at a uniform speed, eliminating the trouble of manual shaking and ensuring the titration effect, but also eliminates external color interference and facilitates color comparison.
[0007] The technical means adopted in this utility model are as follows:
[0008] A titration stage for easy observation includes a support mechanism; it also includes a clamping mechanism, a fixing mechanism, a rotating mechanism, a comparison mechanism, and a shielding mechanism. The clamping mechanism is mounted on the support mechanism and clamps the test tubes; the fixing mechanism is mounted on the support mechanism and fixes the container; the rotating mechanism is mounted on the fixing mechanism and drives the fixing mechanism and the container to rotate; the comparison mechanism is mounted on the support mechanism and facilitates color comparison by the operator; the shielding mechanism is mounted on the comparison mechanism and reduces external color interference. The operator levels the support mechanism on the work surface, places the test tubes on the clamping mechanism, places the container on the fixing mechanism, and drips the solution from the test tubes into the container to react. The rotating mechanism drives the fixing mechanism and the container to rotate, making the solution mix evenly. The shielding mechanism isolates external color interference, and the operator compares the colors of the solutions in the comparison mechanism and the container.
[0009] Furthermore, the support mechanism includes a base, four sets of adjustable legs, four sets of shock-absorbing pads, and a control panel. The base has an internal cavity. The tops of the four sets of adjustable legs are connected to the bottom of the base, and the tops of the four sets of shock-absorbing pads are connected to the bottoms of the four sets of adjustable legs. The control panel is mounted on the base. The operator adjusts the four sets of adjustable legs to keep the base level. The stability of the device is improved by setting the four sets of shock-absorbing pads. The operator controls the clamping mechanism to adjust its height and drives the rotation mechanism through the control panel.
[0010] Furthermore, the clamping mechanism includes a column, a connecting plate, a butterfly clamp, and an electric cylinder. The bottom end of the column is connected to the top end of the base. The connecting plate is slidably mounted on the column. The butterfly clamp is mounted on the connecting plate. The bottom end of the electric cylinder is connected to the top end of the base, and the top end of the electric cylinder is connected to the bottom end of the connecting plate. The operator fixes the test tube on the butterfly clamp, and the electric cylinder pulls the connecting plate down to ensure that the solution in the test tube drips into the container.
[0011] Furthermore, the fixing mechanism includes a limiting ring, a fixing seat, six sets of springs, and three sets of anti-slip clamps. The limiting ring is installed on the base, the fixing seat is rotatably installed on the limiting ring, the six sets of springs are all installed on the inner wall of the fixing seat, and the three sets of anti-slip clamps are respectively installed on the six sets of springs. When the worker places the container on the fixing seat, the six sets of springs push the three sets of anti-slip clamps to hold the bottom of the container and fix the container.
[0012] Furthermore, the rotating mechanism includes a heat dissipation grille, a motor, a reducer, and a drive shaft. The heat dissipation grille is installed in the cavity of the base, and the motor is also installed in the cavity of the base. The power output end of the motor is connected to the power input end of the reducer, which in turn is connected to the power input end of the drive shaft. The power output end of the drive shaft is connected to the power input end of the fixed base. When the motor is started, it drives the drive shaft to rotate via the reducer. The drive shaft then drives the fixed base to rotate, which in turn drives the container to rotate, ensuring uniform mixing of the solution. The heat dissipation grille facilitates heat dissipation during device operation.
[0013] Furthermore, the comparison mechanism includes a protective box, a knob, and a colorimetric tape. The bottom of the protective box is connected to the top of the base. The knob is mounted on the protective box and the colorimetric tape is mounted on the knob. When the operator rotates the knob, the knob drives the colorimetric tape to rotate. The colorimetric tape displays one color at a time, which is convenient for the operator to compare with the color of the solution in the container.
[0014] Furthermore, the shielding mechanism includes a light shield, a universal tube, and an LED light. The bottom end of the light shield is connected to the top end of the base, the universal tube is mounted on the protective box, and the LED light is mounted on the knob. By setting the light shield, external light sources and colors are blocked, making it easier to compare the colors of the solution. When the light is insufficient, the position of the LED light can be adjusted through the universal tube to illuminate the solution, making it easier for staff to observe and compare.
