Description
Technical Field
The utility model relates to an appurtenance technical field, concretely relates to capillary tube chromatographic column base post wind.
Background
The principle of the gas chromatograph is that the mixture is separated by using the difference of boiling point, polarity and adsorption property of the material, the sample to be analyzed is gasified in the gasifying chamber and then brought into the chromatographic column by inert gas (i.e. carrier gas, also called mobile phase), the column contains liquid or solid fixed phase, each component in the sample tends to form distribution or adsorption equilibrium between the mobile phase and the fixed phase, along with the flow of the carrier gas, the components of the sample are repeatedly distributed or adsorbed/desorbed in the movement, the component with high distribution concentration in the carrier gas flows out of the chromatographic column first, and the component with high distribution concentration in the fixed phase flows out, and the component flows out of the chromatographic column and then enters the detector for measurement, while the capillary column is an indispensable component in the gas chromatograph.
At present, the traditional capillary chromatographic columns adopted in the market are generally subjected to cross-linking treatment through the capillary base columns in the manufacturing process, when the capillary base columns are transported or sold, the capillary base columns are coiled into a round disk, the length of the capillary base columns can reach tens of thousands of meters or even tens of thousands of meters, and when the capillary chromatographic columns are manufactured, operators are required to manually drag the capillary base columns to wind the capillary base columns on a capillary column frame, so that the mode is relatively labor-consuming, time-wasting and not beneficial to saving of production cost.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned problem that prior art exists, this application provides a capillary chromatographic column base column wind, and its simple structure, labour saving and time saving, low cost are favorable to improving capillary chromatographic column production efficiency.
In order to achieve the purpose, the technical scheme of the application is as follows: the utility model provides a capillary chromatographic column base column wind, includes bottom plate, vertical scroll, bearing, branch, bracket and locating lever, the welding has the vertical scroll on the bottom plate, and this vertical scroll lower part has cup jointed the bearing, the welding has the bracket on the bearing, be equipped with the branch of welding on the vertical scroll below the bracket, branch both ends swing joint has the locating lever.
Furthermore, positioning bar holes are symmetrically formed in two sides of the supporting rod, and a positioning rod connected in each positioning bar hole is fixed with the supporting rod through a hand-tightening screw.
Furthermore, the distance between the positioning rods is matched with the diameter of the disc wound with the capillary base column.
Furthermore, the bracket is of a cross structure with radian and used for supporting a disc wound with the capillary base column.

Detailed Description
The embodiment of the present invention is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are provided, but the present invention is not limited to the following embodiments.
Example 1
As shown in fig. 1-3, the present embodiment provides a capillary chromatographic column base column winding device, which includes a bottom plate, a vertical shaft, a bearing, a supporting rod, a bracket and a positioning rod, wherein the vertical shaft is welded on the bottom plate, the bearing is sleeved on the lower portion of the vertical shaft, the bracket is welded on the bearing, the supporting rod welded on the vertical shaft is arranged below the bracket, and the positioning rod is movably connected to two ends of the supporting rod.
Because the lengths of the capillary base columns wound on the disc are different, the diameters formed by the capillary base columns are different, so that the capillary base columns are suitable for sizes with different diameters, positioning bar holes are symmetrically formed in two sides of the supporting rod, and a positioning rod connected in each positioning bar hole is fixed with the supporting rod through a hand-tightening screw. The positioning rod is arranged to block the capillary base column to avoid scattering.
The periphery of the vertical shaft is sleeved with a disc wound with a capillary base column, the disc is positioned on a cross-shaped bracket, the cross-shaped bracket is of an arc-shaped structure, the height of the cross-shaped bracket is slightly larger than that of a bearing, and materials can be saved while the strength is ensured.
The bottom plate is of a square unfilled corner structure and is used for supporting the whole device.
During the use, place the disc that has the capillary pillar on the cross bracket with the winding, operating personnel drag system capillary pillar when winding it on the capillary column frame, owing to drag its disc of system power and can rotate along with the bracket together, consequently reduced physical demands, and can save operating time, be favorable to improving capillary chromatographic column production efficiency.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
