Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of gas chromatography pipeline collection, and in particular relates to a pipeline line collector of a gas chromatograph. Background Art
[0002] The Chinese utility model application number is 2023209693166, which discloses a winding device for a gas chromatography column, through which long pipelines can be wound and fixed through a fixed frame for unified storage. In the laboratory, it is usually necessary to be connected to multiple gases for the instrument to be used normally. Whenever multiple instruments are connected in the laboratory, the pipelines will appear very messy. At the same time, if the above-mentioned winding device is placed on the laboratory bench, it will also take up a relatively large space. If it is placed on the top of the instrument, it is easy to slip if it is accidentally touched. Summary of the invention
[0003] The utility model aims to provide a pipeline line collector of a gas chromatograph, which has the advantages of not occupying the experimental table area and being able to accommodate different gas line pipes.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0005] A pipeline line collector for a gas chromatograph comprises a wire frame, a gas valve and a winding column which can be detachably fixed to a laboratory table; the winding column comprises an upper column and a lower column, the ends of the upper column and the lower column facing away from each other are rotatably connected to the inner wall of the wire frame respectively, and the upper column and the lower column are plugged and fixed on opposite sides; a pipeline inlet and a pipeline outlet are arranged on the side edge of the wire frame, and the pipeline is wound on the winding column; the gas outlet of the gas valve is connected to the pipeline, and the gas inlet of the gas valve is connected to the gas tank.
[0006] Among them, the wireframe can be fixed under the table top of the laboratory bench and does not need to be placed on the laboratory bench, and will not occupy the usable area of the laboratory bench.
[0007] At the same time, different wire tubes can be wound on the winding pole, and the winding pole is rotatable, which is convenient for the staff to adjust the length of the wire tube in a small range. And the wire tube is installed on the inside of the wire frame, so the wire tube will not appear messy on the experimental table.
[0008] The winding pole is assembled by plugging and fixing the upper pole and the lower pole. Firstly, it is convenient for the staff to assemble and disassemble, and is conducive to its storage and processing; secondly, it is conducive to dividing the wire tube into the part wound on the upper pole and the part wound on the lower pole, avoiding all the wire tubes from being entangled together, causing the wire tubes to become tangled.
[0009] Preferably, the pipeline line collector further comprises a rotating bearing, which is installed at the rotating connection between the upper column and the lower column and the inner side wall of the wire frame.
[0010] The function of the rotating bearing is to facilitate the rotating connection between the upper column and the lower column and the inner wall of the wire frame. If only a rotating groove is provided in the inner wall of the wire frame, and the ends of the upper column and the lower column are inserted, this purpose can also be achieved, but the rotating effect is not as good as the rotating bearing effect.
[0011] Preferably, a sleeve rod is provided at one end of the lower column facing the upper column, and correspondingly, an insertion column which is plugged and fixed to the sleeve rod is provided at the end of the upper column.
[0012] A plug-in fixed structure is formed between the sleeve rod and the plug post, which is convenient for disassembly and installation.
[0013] Preferably, the gas valve is provided with an air inlet interface, which is connected to the gas tank by screwing the air inlet pipe. The air inlet interface and the air inlet pipe are screwed and fixed, and after tightening, gas leakage can be avoided.
[0014] Preferably, the air valve is provided with an air outlet interface, which is connected to the instrument through a screw pipe.
[0015] Preferably, an upper extension portion is provided at the upper end of the wire frame, and a threaded hole is provided in the upper extension portion, and a fixing bolt is provided in the threaded hole.
[0016] The upper extension part is fixed to the bottom surface of the test bench by screwing bolts into the threaded holes, thus preventing the wire frame from falling due to accidental touch by staff.
[0017] Preferably, a gas flow meter is installed on the gas valve. The gas flow meter is mainly used to determine whether there is gas passing through the line pipe. Then, the gas flow rate can be read to determine whether it is within a suitable range.
[0018] Preferably, a pressure gauge is installed on the air valve.
[0019] Compared with the prior art, the beneficial effects of the utility model are:
[0020] 1. After the wire tube is wound on the winding pole, it is installed on the inside of the wire frame. And the wire frame is fixed to the bottom end surface of the laboratory table to avoid occupying the space on the laboratory table.
[0021] 2. Multiple groups of unused gas pipes can be wound and fixed on different groups of winding poles to store the pipes and avoid the clutter and tangling caused by multiple pipes. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 2 A structural diagram of a pipeline line collector of a gas chromatograph (back);

DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example
[0027] Based on the above description, this embodiment further provides a supplementary explanation of the pipeline line collector of the gas chromatograph from the perspective of practical application:
[0028] A pipeline line collector for a gas chromatograph, comprising a wire frame 5;
[0029] Air valve 9;
[0030] winding pole;
[0031] The winding column includes an upper column 16 and a lower column 18;
[0032] The bearing 20 is rotated.
[0033] (1) When multiple gas connections are required, wire tubes for different purposes can be wound around the winding pole. Figure 2 As shown, the left side is the state after the wire tube is wound. The wire tube passes through the pipeline inlet from the lower end and is then wound around the lower column 18. At this time, the staff pre-judges the approximate length required when adjusting the length of the wire tube, for example, more than half of the wire tube length will be wound around the lower column 18. Then, the remaining wire tube length is wound around the upper column 16. This design can prevent the wire tube from being embedded in the gap when the wire is discharged, causing a knot problem. Figure 2 The right side is unused. If there are other wire tubes, they can also be wound on the winding pole on the right side. At this time, correspondingly, if the gas also needs to be connected to the gas valve 9, the gas valve can be set in multiple or purchased with multiple through holes to meet the needs.
[0034] (2) After the wire tube is wound, it is placed inside the wire frame. The upper extension is fixed to the inner bottom of the test bench by bolts. The fixed position is a place that is not easily seen by the staff, and it does not take up space on the test bench. By using this device, the wire tube can be neatly stored, which is helpful to avoid the wire tube from being tangled or messy.
