Description

Technical Field

[0001] This utility model relates to an adjustable support for a gas chromatograph, belonging to the technical field of gas chromatograph support. Background Technology

[0002] A gas chromatograph (GC) is an instrument used to separate and analyze compounds. Its working principle involves evaporating the sample into a gaseous state, then separating it through a chromatographic column. Finally, a detector detects the signals of each component. It is typically used to analyze thermally stable organic compounds in soil with boiling points not exceeding 500°C, such as volatile organic compounds, organochlorines, organophosphorus compounds, polycyclic aromatic hydrocarbons, and phthalates. GC is widely used in analytical and detection work in fields such as chemistry, biology, and the environment. In practical applications, the separation and detection of different compounds can be achieved by adjusting parameters such as the type of chromatographic column, temperature, and carrier gas flow rate.

[0003] Gas chromatographs vibrate during operation. If placed directly on a table, the gas chromatograph will shift due to vibration, making its position unstable. Existing supports often use two clamps to hold the gas chromatograph, which can only clamp the two sides of the instrument. This can lead to unstable clamping, causing the instrument to fall off the support and damage the equipment. To address this, we propose an adjustable support for gas chromatographs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an adjustable support for a gas chromatograph, which solves the problem of unstable clamping of the chromatograph in the prior art.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0006] An adjustable support for a gas chromatograph includes a positioning frame and a base plate. An electric push rod is fixedly connected to the inner wall of the positioning frame. A clamping frame is fixedly connected to the end of the electric push rod away from the positioning frame. A sliding groove is opened inside the clamping frame, and a clamping rod is slidably connected inside the sliding groove. A threaded seat is fixedly connected to one side of the clamping rod, and the other side of the clamping rod extends to the outside of the clamping frame. A bearing seat is fixedly connected to one side of the clamping frame. A bidirectional screw is installed inside the bearing seat through a bearing. The bidirectional screw is threaded into the inside of the threaded seat. A height adjustment component for adjusting the height of the positioning frame is installed on the base plate.

[0007] By adopting the above technical solution, when clamping the gas chromatograph, the gas chromatograph can first be placed on the base plate frame, and then the electric push rod can be activated. The electric push rod can drive the clamping frame to move, and the two clamping frames can contact the two sides of the gas chromatograph to clamp the left and right sides of the gas chromatograph. Then, the operator rotates the bidirectional screw, which can drive the threaded seat to move, so that the clamping rod moves inside the slide groove to clamp the front and back of the gas chromatograph. After two limiting actions, the gas chromatograph can be clamped more stably. When the gas chromatograph is running, it can be more firmly installed inside the support, with better stability and less likely to fall off the support. When the gas chromatograph is transported, the operator can loosen the positioning handle and move the adjusting rod upward from inside the fixed tube to adjust the height of the positioning frame. After adjusting to the required height, the operator can activate the electric push rod again to clamp the gas chromatograph. The adjusted support can also shield the gas chromatograph, providing protection and reducing the probability of it being bumped during transport.

[0008] The present invention is further configured such that: the height adjustment component includes a fixed tube, an adjusting rod and a positioning handle, the fixed tube is fixedly installed on the base plate frame, and the adjusting rod is inserted into the inside of the fixed tube and connected through the positioning handle.

[0009] By adopting the above technical solution, the adjusting rod moves upward inside the fixed tube, which can change the height of the positioning frame. The positioning handle can limit the adjusting rod, so that after the adjusting rod is adjusted in height, it is stably kept inside the fixed tube.

[0010] The present invention is further configured as follows: a mounting plate is fixedly connected to the positioning frame, a lower clamping seat is fixedly connected to the mounting plate, a limit frame is fixedly connected to the lower clamping seat, a limit rod is slidably connected inside the limit frame, an upper clamping seat is fixedly connected to one end of the limit rod, a threaded column is installed on the outer surface of the upper clamping seat through a bearing, the threaded column is threadedly connected to the inside of the limit frame, and a handle is fixedly connected to the top of the threaded column.

[0011] By adopting the above technical solution, after the staff places the cable or pipe inside the lower clamp in different positions, the staff turns the handle, which drives the threaded column to rotate, which can control the upper clamp to move downward, clamping and fixing the cable or pipe inside the lower clamp, making the cable and pipe arrangement more regular and orderly.

[0012] The present invention is further provided that protective pads are fixedly connected to both the clamping frame and the clamping rod.

[0013] By adopting the above technical solution, the protective pad can prevent the clamping frame and clamping rod from directly contacting the gas chromatograph, thereby reducing damage to the gas chromatograph during clamping.

[0014] The present invention is further configured such that: an anti-slip pad is fixedly connected to the base plate frame, and the base plate frame is inverted U-shaped with several ventilation holes.

[0015] By adopting the above technical solution, the anti-slip pad has a large friction with the tabletop, which makes the bracket less likely to slide when placed on the tabletop. In addition, the middle of the base plate has a certain gap with the ground, which helps to dissipate heat from the gas chromatograph with the help of the ventilation holes.

[0016] The beneficial effects of this utility model are as follows: When clamping the gas chromatograph, the gas chromatograph can be placed on the base plate first, and then the electric push rod can be started. The electric push rod can drive the clamping frame to move, and the two clamping frames can contact the two sides of the gas chromatograph to clamp the left and right sides of the gas chromatograph. Then, the operator rotates the bidirectional screw, which can drive the threaded seat to move, so that the clamping rod moves inside the slide groove to clamp the front and back of the gas chromatograph. After two limiting actions, the gas chromatograph can be clamped more stably. When the gas chromatograph is running, it can be more stably installed inside the support, with better stability and less likely to fall off the support. Attached Figure Description

[0024] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0025] Example 1

[0026] like Figures 1 to 6 As shown, an adjustable support for a gas chromatograph includes a positioning frame 1 and a base plate 9. The positioning frame 1 is U-shaped, which facilitates operation of the gas chromatograph after clamping it. Electric push rods 2 are fixedly connected to the inner walls of the positioning frame 1. A clamping frame 3 is fixedly connected to the end of the electric push rod 2 away from the positioning frame 1. Slide grooves 4 are respectively opened at both ends inside the clamping frame 3, extending along the extension direction of the clamping frame 3. Openings penetrating the clamping frames 3 are also opened on the sides of the two clamping frames 3 that are far apart from each other. A clamping rod 5 is slidably connected inside the slide groove 4. A threaded seat 6 extending through the opening of the slide groove 4 to the outside of the clamping frame 3 is fixedly connected to one side of the clamping rod 5. The other side of the clamping rod 5 extends to the outside of the clamping frame 3. A bearing seat 7 is fixedly connected to the side of the clamping frame 3 where the slide groove 4 opening is located. A bidirectional screw 8 is installed inside the bearing seat 7 via a bearing. The two ends of the bidirectional screw 8... The bidirectional screw 8 has two threads with opposite helical directions. The two threads with opposite helical directions are respectively threadedly connected to the threaded seats 6 in the two slide grooves 4. When the bidirectional screw 8 rotates, it can simultaneously control the two threaded seats 6 to move in opposite directions. A height adjustment component for adjusting the height of the positioning frame 1 is installed on the base plate frame 9. The height adjustment component includes a fixed tube 10, an adjusting rod 11, and a positioning handle 12. The fixed tube 10 is fixedly installed on the base plate frame 9. The adjusting rod 11 is inserted into the fixed tube 10 and connected through the positioning handle 12. A threaded rod is fixedly installed on the positioning handle 12. The threaded rod is threadedly connected to the inside of the fixed tube 10. When the positioning handle 12 rotates, the threaded rod can rotate. As the threaded rod rotates, one end of the threaded rod will approach the adjusting rod 11 and directly abut against the adjusting rod 11, so that the adjusting rod 11 can be more firmly fixed inside the fixed tube 10.

[0027] like Figure 1 and Figure 4As shown, a mounting plate 13 is fixedly connected to the positioning frame 1. The mounting plate 13 is fixedly installed on the upper surface of the positioning frame 1 by bolts. A lower clamping seat 14 is fixedly connected to the mounting plate 13. There are multiple lower clamping seats 14. A limit frame 15 is fixedly connected to the lower clamping seat 14. A limit rod 16 is slidably connected inside the limit frame 15. Positioning grooves extending vertically are opened on both sides of the limit frame 15. The limit rod 16 is slidably connected inside the positioning groove. The positioning groove can limit the movement trajectory of the limit rod 16. An upper clamping seat 17 is fixedly connected to one end of the limit rod 16. A threaded post 18 is installed on the outer surface of the upper clamping seat 17 through a bearing. The threaded post 18 is threadedly connected to... Inside the limiting frame 15, the rotation of the threaded post 18 allows it to move downwards or downwards. During this movement, the threaded post 18 pushes the upper clamping seat 17 to move synchronously. Because the positioning groove on the limiting frame 15 limits the limiting rod 16, the upper clamping seat 17 moves more stably up and down. A handle 19 is fixedly connected to the top of the threaded post 18. After the operator places the cable or pipe inside the lower clamping seat 14 at different positions, the operator rotates the handle 19. The handle 19 drives the threaded post 18 to rotate, which controls the upper clamping seat 17 to move downwards, clamping and fixing the cable or pipe inside the lower clamping seat 14, making the cable and pipe arrangement more regular and orderly.

[0028] like Figure 2 and Figure 3 As shown, protective pads 20 are fixedly connected to both the clamping frame 3 and the clamping rod 5. The protective pads 20 on the clamping frame 3 are installed on the side of the clamping frame 3, and the protective pads 20 on the clamping rod 5 are installed on the inner wall of the clamping rod 5. When clamping the gas chromatograph, the protective pads 20 can prevent the clamping frame 3 and the clamping rod 5 from directly contacting the gas chromatograph, thus protecting the gas chromatograph. Anti-slip pads 21 are fixedly connected to the base plate frame 9, and the base plate frame 9 is inverted U-shaped. Several ventilation holes 22 are opened on the base plate frame 9. The anti-slip pads 21 have a large friction with the table, which can make the bracket less likely to slide when placed on the table. In addition, there is a certain gap between the middle of the base plate frame 9 and the ground. With the help of the ventilation holes 22, it helps to dissipate heat from the gas chromatograph.

[0029] When clamping the gas chromatograph, first place the gas chromatograph on the base plate 9, then activate the electric push rod 2. The electric push rod 2 will move the clamping frame 3, allowing the two clamping frames 3 to contact the two sides of the gas chromatograph, clamping the left and right sides of the gas chromatograph. Then, the operator rotates the bidirectional screw 8, which will move the threaded seat 6, causing the clamping rod 5 to move inside the slide groove 4, clamping the gas chromatograph from front to back. After two limiting actions, the gas chromatograph can be clamped more securely. When the gas chromatograph is running, it can be more securely installed inside the support, with better stability and less likely to fall off the support. When the gas chromatograph is transported, the operator can loosen the positioning handle 12 and move the adjusting rod 11 upward from inside the fixing tube 10 to adjust the height of the positioning frame 1. After adjusting to the required height, the operator can restart the electric push rod 2 to clamp the gas chromatograph. The adjusted support can also shield the gas chromatograph, providing protection and reducing the probability of it being bumped during transport.

Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model.
