Description

Technical Field

[0001] This utility model relates to the field of oil chromatography degassing technology, and more specifically, to an oil chromatography test degassing tray oscillation mechanism. Background Technology

[0002] The degassing step in oil chromatography is to ensure the accuracy and reliability of the analytical results, because dissolved gases in the oil may affect the accuracy of chromatographic analysis. Commonly used degassing methods include thin-film permeation, vacuum degassing, and headspace sampling. Among these methods, the oscillation degassing method applies Henry's law and is based on the analytical principle of headspace (liquid) chromatography. A certain amount of nitrogen gas is added to an oil sample in a closed container, and after thorough shaking, the oil and gas phases are brought into equilibrium. By analyzing the content of gas phase components, the content of gas components in the oil sample can be determined.

[0003] Chinese patent application number CN202321412967.1 discloses an oil chromatography test degassing tray oscillation mechanism, including a syringe and a rotating disk. The rotating disk has several through holes on its circumference for inserting syringes. A servo motor is provided at the bottom of the rotating disk to rotate the disk. An electric push rod is provided on one side of the rotating disk. The output end of the electric push rod is provided with a push plate that can abut the syringe. Multiple syringes are placed vertically in a rotating disk. The servo motor reverses the rotation in a certain direction at a certain time to achieve oscillation and degassing, realizes the concentrated oscillation of multiple samples, improves work efficiency, and increases the repeatability and accuracy of analysis results.

[0004] However, as can be seen from the accompanying drawings in the instruction manual, the through hole for installing the syringe is fixed in size. When the syringe diameter changes, the through hole cannot fix the syringe, making it inconvenient to install and fix syringes of different diameters, which affects practicality. Therefore, an oil chromatography test degassing tray oscillation mechanism is proposed. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an oil chromatography test degassing tray oscillation mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oil chromatography test degassing tray oscillation mechanism, including an upper clamping turntable, a lower clamping turntable at the bottom of the upper clamping turntable, and a support plate at the bottom of the lower clamping turntable. Through holes are correspondingly opened on the surfaces of the upper and lower clamping turntables, through which syringes for storing samples can be placed. Multiple stabilizing baffles and a first connecting rod are fixedly connected to the bottom of the upper clamping turntable. The stabilizing baffles connect the upper and lower clamping turntables, and the first connecting rod connects the upper clamping turntable, the lower clamping turntable, and the support plate.

[0007] A reducer is located at the center of the bottom of the lower clamping turntable, and a servo motor is located at the bottom of the reducer. Top holes are opened around the support plate. A stepper motor is fixedly connected to the top of the upper clamping turntable. When the servo motor is started, the upper clamping turntable, the lower clamping turntable, and the support plate are rotated through the reducer. This allows the syringe inserted in the center of the through hole to move back and forth, thereby achieving an oscillation effect. The top hole also allows the bottom push rod to move the syringe upward for use.

[0008] The output end of the stepper motor is fixedly connected to a turntable. Multiple second connecting rods are fixedly connected to the top of the turntable. A pressing plate is provided on the side of the stabilizing baffle near the turntable. A fixed base and a stabilizing plate are fixedly connected to one side of the pressing plate. A connecting push rod is rotatably connected to the middle of the fixed base. A limiting groove is formed in the middle of the stabilizing plate, and a limiting slider is provided in the middle of the limiting groove. Starting the stepper motor controls the turntable to rotate. The connecting push rod can be controlled by the second connecting rods to push the pressing plate. Through the cooperation of the limiting slider and the stabilizing plate, the stability of the pressing plate's movement can be improved, thereby controlling the pressing plate to move towards the side of the stabilizing baffle. By cooperating with the stabilizing baffle, a syringe located on one side of the stabilizing baffle can be pressed and fixed, facilitating the clamping and fixing of syringes of different diameters, making it easy to adapt to use, and improving the fixing strength.

[0009] Preferably, the stabilizing baffle corresponds one-to-one with the through hole, the stabilizing baffle is configured as an arc-shaped structure, and the stabilizing baffle is oriented towards the side closer to the turntable, so as to protect the syringe side located in the inner cavity of the through hole.

[0010] Preferably, there are four first connecting rods, which are fixed around the bottom of the upper clamping turntable. The first connecting rods pass through the lower clamping turntable and are fixedly connected to the support plate. The stability of the connection between the upper clamping turntable, the lower clamping turntable, and the support plate is improved by the first connecting rods.

[0011] Preferably, the number of top holes is the same as the number of through holes, and the top holes and through holes correspond to the side of the inner cavity of the through holes that is close to the stabilizing baffle. The first connecting rod facilitates the push rod to push one end of the syringe.

[0012] Preferably, the output end of the reducer is fixedly connected to the bottom wall of the lower clamping turntable, and the output end of the servo motor is fixedly connected to the input end of the reducer. Starting the servo motor controls the rotation of the upper clamping turntable through the reducer, which is convenient for oscillation.

[0013] Preferably, the connecting push rod and the second connecting rod are in one-to-one correspondence. One end of the connecting push rod is fitted into the middle of the second connecting rod. The extrusion plate is set with an arc-shaped structure. The extrusion plate corresponds to the stabilizing baffle. The movement of the second connecting rod is controlled by the rotation of the turntable. The movement of the extrusion plate can be controlled by the connecting push rod, which is convenient for driving and use.

[0014] Preferably, the stabilizing plate is located at both ends on one side of the extrusion plate, and the cross-sectional shape of the limiting slider is set to "T". Multiple limiting sliders are respectively fixed on the opposite side wall of the upper clamping turntable and the lower clamping turntable. Through the cooperation of the limiting slider and the limiting groove, the stability of the stabilizing plate movement is improved, thereby improving the stability of the extrusion plate movement and improving the use effect.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model firstly uses a through hole to facilitate the limiting of the syringe, and controls the rotation of the turntable by starting the stepper motor. The movement of the connecting push rod can be controlled by the second connecting rod, thereby pushing the extrusion plate. The stability of the extrusion plate movement is improved by the cooperation of the stabilizing plate and the limiting slide groove with the limiting slider. The extrusion plate and the stabilizing baffle cooperate to achieve the extrusion and fixation of the syringe, thus facilitating the clamping and fixing of syringes of different diameters and making it convenient to use.

[0017] 2. This utility model also controls the rotation of the upper and lower clamping turntables by starting the servo motor and rotating it in both directions at a certain reversal time, thereby driving the syringe to oscillate and achieve degassing. It also enables concentrated oscillation of multiple samples, improving work efficiency. Furthermore, the connection stability between the upper and lower clamping turntables is improved by the stabilizing baffle and the first connecting rod. The bottom of the placed syringe is supported by the support plate, and the top hole does not affect the pushing of the bottom of the syringe, thus improving the usage effect.

[0018] In summary, through the interaction of the above-mentioned multiple functions, it is possible to conveniently clamp and fix syringes of different diameters, making them easy to use. Furthermore, the clamping turntable can be oscillated, thereby driving multiple syringes to oscillate and degas, achieving concentrated oscillation of multiple samples and improving work efficiency.

This allows the syringe inserted in the middle of the through hole 4 to move back and forth, thereby achieving an oscillation effect. The syringe can be moved upward by the bottom push rod through the top hole 9.

Through the cooperation of the limit slider 18 and the stabilizing plate 16, the stability of the movement of the squeezing plate 13 can be improved, thereby controlling the squeezing plate 13 to move towards one side of the stabilizing baffle 5. By cooperating with the stabilizing baffle 5, the syringe located on one side of the stabilizing baffle 5 can be squeezed and fixed, which is convenient for clamping and fixing syringes of different diameters, making it easy to adapt to use and improving the fixing strength.

[0029] As attached Figure 1-5 As shown, the stabilizing baffle 5 corresponds one-to-one with the through hole 4. The stabilizing baffle 5 is set with an arc-shaped structure, and the stabilizing baffle 5 is oriented towards the side closer to the turntable 11. There are four first connecting rods 6, which are fixed around the bottom of the upper clamping turntable 1.

At both ends, the cross-sectional shape of the limiting slider 18 is set to "T" shape.

The rotation of the turntable 11 controls the movement of the second connecting rod 12. The extrusion plate 13 can be moved by the connecting push rod 15 for easy driving. The cooperation of the limiting slider 18 and the limiting groove 17 improves the stability of the movement of the stabilizing plate 16, thereby improving the stability of the movement of the extrusion plate 13 and improving the use effect.

[0030] The working principle of this utility model is as follows: When in use, the syringe is placed inside the through hole 4. At this time, the syringe is located between the stabilizing baffle 5 and the squeezing plate 13. Then, the stepper motor 10 is started to control the squeezing plate 13 to move to one side of the stabilizing baffle 5 to squeeze and fix the syringe. It can also be easily adapted to clamp and fix syringes of different diameters, making it convenient to use. Furthermore, by starting the servo motor 8 and rotating it in both directions at a certain reversal time, the upper clamping turntable 1 and the lower clamping turntable 2 can be controlled to rotate, thereby driving the syringe to oscillate and achieve degassing. This enables concentrated oscillation of multiple samples and improves work efficiency.
