Detailed Implementation

[0020] 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.

[0021] This utility model provides, for example Figure 1-3The universal gas chromatography column installation tool shown includes:

[0022] Mounting plate 1, with a scale 2 fixedly connected to the top side of the mounting plate 1, and a ceramic blade 4 for cutting gas chromatography columns is provided on the top of the mounting plate 1. Support assembly 3 is also located on the top of the mounting plate 1, comprising two first support plates 31 and two second support plates 33. When installing and cutting the gas chromatography column, the gas chromatography column is first installed inside the gas chromatography column mounting housing using nuts and sealing washers. The gas chromatography column has protruding parts at both ends, so the protruding gas chromatography columns at both ends of the housing are located on the second support plates 33. The ceramic blade 4 can then quantitatively cut the gas chromatography column on the second support plates 33. The two second support plates 33 are located on the sides of the two first support plates 31. The two first support plates 31 are used to support the gas chromatography column, and the second support plates 33 cooperate with the ceramic blade 4 to cut the gas chromatography column.

[0023] Furthermore, a bearing housing 5 is fixedly connected to the middle of the upper surface of the mounting plate 1. The ceramic blade 4 is slidably sleeved inside the bearing housing 5. The bearing housing 5 and the ceramic blade 4 have a certain compressive force, so that the ceramic blade 4 is placed and stored on the mounting plate 1. The ceramic blade 4 can be taken out of the bearing housing 5 by using the protrusion 6. A notch is opened on the side of the top of the bearing housing 5. The protrusion 6 is fixedly connected to the side of the top of the ceramic blade 4.

[0024] Furthermore, the top of the first support plate 31 is provided with a support groove 32. The housing for mounting the gas chromatography column can be located in the support groove 32 on the top of the two first support plates 31, and the nuts and sealing washers at both ends of the housing are located on opposite sides of the two first support plates 31. Then, the gas chromatography column at both ends of the housing is located in the first slot 34 on the second support plate 33. Then, the ceramic blade 4 slides from the second slot 35 to quantitatively cut the gas chromatography column. The top of the second support plate 33 is provided with a first slot 34 and a second slot 35. The first slot 34 and the second slot 35 are arranged in a crisscross pattern.

[0025] Furthermore, two connecting rods 36 are fixedly connected to opposite sides of the two second support plates 33. Two through holes are opened on one side of the first support plate 31. The outer wall of the connecting rod 36 is slidably sleeved with the inner cavity of the through hole. First positioning bolts 37 are threadedly sleeved on both sides of the first support plate 31. Loosening the first positioning bolts 37 allows the second support plate 33 to slide relative to the first support plate 31 through the connecting rods 36. The distance between the second support plate 33 and the first support plate 31 is changed by using the scale 2 as a reference, thereby changing the length of the gas chromatography column. One end of the first positioning bolt 37 is pressed and fitted against the outer wall of the connecting rod 36.

[0026] Furthermore, a slider 38 is fixedly connected to the bottom of the first support plate 31. Two sliding holes 39 are opened on the top of the mounting plate 1. The outer wall of the slider 38 is slidably sleeved with the inner cavity of the sliding hole 39. By loosening the second positioning bolt 311 and referring to the scale 2, the first support plate 31 slides relative to the mounting plate 1. By changing the distance between the two first support plates 31, it can support gas chromatograph column shells of different lengths. A positioning plate 310 is fixedly connected to the bottom of the slider 38. The second positioning bolts 311 are threaded and sleeved on both sides of the bottom of the positioning plate 310. The top of the second positioning bolts 311 is pressed and fitted against the mounting plate 1, thereby tightening the second positioning bolts 311. This allows the positioning plate 310 and the slider 38 to limit the position of the first support plate 31. The bottom of the positioning plate 310 is provided with an inner bolt. The positioning plate 310 is fixedly connected to the slider 38 through the inner bolt. By removing the inner bolt, the positioning plate 310 can be separated from the slider 38, thereby allowing the first support plate 31 to be disassembled, replaced, and maintained.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
