Description

Technical Field

[0001] This utility model relates to the field of capillary support technology, and in particular to a capillary support for a gas chromatograph. Background Technology

[0002] Capillary chromatography is now used for the analysis of various complex mixtures, including atmospheric and environmental pollutants, biological samples, food, mineral fuels, cosmic substances, and some inorganic and organometallic compounds. The capillary column is an important part of the chromatograph. Properly fixing the capillary can extend its lifespan. A capillary is a long and thin tube, and improper placement can easily cause them to stick together and become tangled, affecting the flow of the liquid inside the capillary. In severe cases, the capillary tubes may squeeze each other and break.

[0003] Currently, the capillary placement in gas chromatographs involves three bent steel wires threaded in three different directions through an external hexagonal body. The ends of the two wires are then hooked together, and the capillary is secured by the stretchable wires. This type of capillary support structure is complex, the capillary placement and fixation operation is cumbersome, and it is inconvenient to use. Furthermore, it is impossible to ensure a certain gap between the capillaries, which can easily lead to misalignment and entanglement, affecting the performance of the instrument.

[0004] Therefore, it is necessary to provide a capillary support for a gas chromatograph to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a capillary support for a gas chromatograph to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems: a capillary support for a gas chromatograph, comprising an annular base plate, side plates fixed on the side of the annular base plate, multiple side plates arranged in a ring, a sliding groove arranged along the length of the side plate on the top surface of the side plate, a sliding plate slidably connected in the sliding groove, a vertically arranged support rod fixed on one end of the sliding plate near the center of the annular base plate, a locking assembly provided on the side of the support rod near the center of the annular base plate, and a clamping assembly for clamping and limiting the sliding plate on the top surface of the side plate.

[0007] As a further embodiment of this utility model, the locking assembly includes a plastic spring sheet fixed to the side of the support rod near the center of the annular base plate, and the plastic spring sheet is provided in multiple quantities and the multiple plastic spring sheets are distributed at equal intervals.

[0008] As a further embodiment of this utility model, a first rubber pad is attached and fixed to the inner side of the plastic spring sheet.

[0009] As a further embodiment of this utility model, the clamping assembly includes an L-shaped support plate fixed to the top surface of the side plate, a threaded rod being threadedly connected to the top end of the L-shaped support plate, and a pressure plate for clamping the slide plate being fixed to the bottom end of the threaded rod.

[0010] As a further embodiment of this utility model, an end plate is fixed to the top of the threaded rod, and a rubber sleeve is fitted onto the surface of the end plate.

[0011] As a further embodiment of this utility model, a second rubber pad is attached and fixed to the bottom surface of the pressure plate, and the area of ​​the second rubber pad is equal to the area of ​​the side surface of the pressure plate.

[0012] As a further embodiment of this utility model, an indicator mark is provided on the outer side of the skateboard, and a scale that cooperates with the indicator mark is provided on the top surface of the side plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By inserting one end of the capillary tube into the plastic spring at the bottom of one of the support rods, and then continuously bending the capillary tube into the plastic springs arranged in ascending order, the capillary tube is clamped to a certain extent by the plastic springs. The capillary tube is then wound into multiple plastic springs and placed between multiple support rods. This ensures the stability of the capillary tube placement, resulting in a fixed gap between each turn of the capillary tube. This makes the coiled capillary tube evenly wound and tightly arranged, preventing the capillary tubes from sticking together and tangling due to improper placement, which could affect the flow of the liquid inside the capillary tube or even cause the capillary tubes to break due to mutual compression. This effectively improves the protective performance of the capillary tube placement, and the structure is simple and practical.

[0015] 2. The spacing between multiple support rods can be adjusted by the clamping components, thus adapting to the placement and use of capillary tubes with different winding size specifications. In other words, capillary tubes can be wound into different sizes to meet different usage needs and improve overall practicality. Attached Figure Description

[0024] The present invention will be further described below with reference to the embodiments.

[0025] See also Figure 1-5 This utility model provides a capillary support for a gas chromatograph, including an annular base plate 4. Side plates 5 are fixed to the sides of the annular base plate 4. Multiple side plates 5 are arranged in a ring. A groove 6 is formed on the top surface of each side plate 5 along its length. A sliding plate 7 is slidably connected within the groove 6. A vertically arranged support rod 3 is fixed to one end of the sliding plate 7 near the center of the annular base plate 4. A locking assembly 1 is provided on the side of the support rod 3 near the center of the annular base plate 4. The locking assembly 1 includes multiple plastic springs 101 fixed to the side of the support rod 3 near the center of the annular base plate 4, arranged at equal intervals. A clamping component 2 is provided on the top surface of the side plate 5 to clamp and limit the sliding plate 7. In use, one end of the capillary is inserted into the plastic spring 101 at the bottom of one of the support rods 3, and then the capillary is continuously... The capillary tube is bent and inserted into the upward-facing plastic springs 101, which clamp the capillary tube to a certain extent. The capillary tube is then wound around multiple plastic springs 101 and between multiple support rods 3. This ensures the stability of the capillary tube placement and provides a fixed gap between each turn of the capillary tube. This results in uniform and tight winding of the capillary tube, preventing it from sticking together and tangling due to improper placement, which could affect the flow of the liquid inside the capillary tube or even cause it to break due to mutual compression. This effectively improves the protective properties of the capillary tube. The structure is simple and practical. The spacing between the multiple support rods 3 can be adjusted by the clamping component 2, thus adapting to the placement and use of capillary tubes with different winding sizes and specifications. In other words, capillary tubes can be wound into different sizes and specifications to meet different usage needs and improve overall practicality.

[0026] Further as Figure 3 and Figure 4 As shown, it is worth noting that a first rubber pad 102 is attached and fixed to the inner side of the plastic spring 101. In actual operation, the first rubber pad 102 further increases the friction force of the plastic spring 101 on the capillary, thereby further improving the clamping stability.

[0027] Further as Figure 1 and Figure 2 As shown, it is worth noting that the clamping assembly 2 includes an L-shaped support plate 201 fixed to the top surface of the side plate 5. The top end of the L-shaped support plate 201 is threadedly connected to a threaded rod 202, and the bottom end of the threaded rod 202 is fixed with a pressure plate 204 that clamps the slide plate 7. In actual operation, by rotating the threaded rod 202 up and down, the pressure plate 204 is released from clamping the slide plate 7, thereby allowing the slide plate 7 to slide and adjust. This allows for adjustment of the spacing between the multiple support rods 3, thus adapting to the placement and use of capillary tubes with different winding size specifications. In other words, capillary tubes can be wound into different sizes to meet different usage requirements and improve overall practicality.

[0028] Further as Figure 2 As shown, it is worth noting that the top of the threaded rod 202 is fixed with an end plate 203, and a rubber sleeve is fitted on the surface of the end plate 203; in actual operation, the threaded rod 202 can be easily rotated through the end plate 203, which facilitates operation.

[0029] This solution has the following working process: One end of the capillary tube is inserted into the plastic spring 101 at the bottom of one of the support rods 3. Then, the capillary tube is continuously bent and inserted into the plastic springs 101 arranged in ascending order. The plastic springs 101 provide a small clamping force, which clamps the capillary tube to a certain extent. The capillary tube is then wound into multiple plastic springs 101 and between multiple support rods 3, so that there is a fixed gap between each turn of the capillary tube. This makes the wound capillary tube evenly wound and tightly arranged. By turning the threaded rod 202 up and down, the pressure plate 204 is released from clamping the slide plate 7, so that the slide plate 7 can be slidably adjusted. This allows for adjustment of the spacing between multiple support rods 3, thus adapting to the placement and use of capillary tubes with different winding size specifications. In other words, the capillary tube can be wound into different sizes and specifications.

[0030] Further as Figure 2 As shown, it is worth noting that a second rubber pad 205 is attached and fixed to the bottom surface of the pressure plate 204, and the area of ​​the second rubber pad 205 is equal to the area of ​​the side surface of the pressure plate 204. In actual operation, the second rubber pad 205 effectively improves the stability of the pressure plate 204 in clamping the slide plate 7.

[0031] Further as Figure 1and Figure 2 As shown, it is worth noting that an indicator mark 9 is provided on the outer side of the slide plate 7, and a scale 8 that cooperates with the indicator mark 9 is provided on the top surface of the side plate 5. In actual operation, the adjustment amount of the support rod 3 is indicated by the cooperation of the scale 8 and the indicator mark 9, so as to ensure that the adjustment amount of multiple support rods 3 is consistent.

[0032] In summary: By continuously bending the capillary tube and inserting it into the sequentially upward-facing plastic springs 101, the capillary tube is clamped to a certain extent by the plastic springs 101, thus winding the capillary tube into multiple plastic springs 101 and between multiple support rods 3. This ensures the stability of the capillary tube placement, resulting in a fixed gap between each turn of the capillary tube. This ensures that the wound capillary tube is evenly wound and tightly arranged, preventing the capillary tubes from sticking together and tangling due to improper placement, which could affect the flow of the liquid inside the capillary tube or even cause the capillary tubes to break due to mutual compression. This effectively improves the protective properties of the capillary tube placement. The structure is simple and practical. The spacing between the multiple support rods 3 can be adjusted by the clamping component 2, thus adapting to the placement and use of capillary tubes with different winding sizes and specifications. In other words, capillary tubes can be wound into different sizes and specifications to meet different usage needs and improve overall practicality.
