Description

An auxiliary sample introduction device for organic mass spectrometry detection Technical Field

[0001] This application relates to the field of organic matter detection, and more specifically, it relates to an auxiliary sample introduction device for organic matter mass spectrometry detection. Background Technology

[0002] A thermal desorption instrument is an analytical instrument used in the fields of environmental science and technology and resource science and technology.

[0003] In actual use of the thermal desorption instrument, sample injection is required. The sample is placed in a test tube with sleeves at both ends. Before sending the test tube into the thermal desorption instrument, the sleeves at both ends of the test tube need to be removed. Currently, the separation of the sleeves from the test tube is often done manually, which is inconvenient and needs to be improved. Summary of the Invention

[0004] To address the inconvenience of separating the tube sleeve from the test tube, this application provides an auxiliary sample introduction device for organic mass spectrometry detection.

[0005] This application provides an auxiliary sample introduction device for organic mass spectrometry detection, which adopts the following technical solution:

[0006] An auxiliary sample introduction device for organic mass spectrometry detection includes a worktable with a turntable that rotates on the worktable. A drive component and a clamping cylinder are located at the end of the turntable away from the worktable. The drive component drives the clamping cylinder to move horizontally. The worktable has a frame with a clamping component that slides on the frame in a vertical direction. The clamping component is used to clamp a tube sleeve.

[0007] The above technical solution uses a clamping cylinder to hold the test tube. When separation is required, clamping component one clamps the tube sleeve, then moves clamping component one while the clamping cylinder remains fixed. At this time, the movement of clamping component one separates the tube sleeve from the test tube. Separating the tube sleeve from the test tube in this way makes the overall operation more convenient and the sample injection operation simpler.

[0008] Furthermore, the frame is provided with a second clamping member, which is located on the side of the first clamping member close to the workbench. The second clamping member slides on the frame, and the sliding direction of the second clamping member is consistent with the sliding direction of the first clamping member.

[0009] With the above technical solution, in actual use, both ends of the test tube are equipped with tube sleeves. Therefore, it is necessary to separate the tube sleeves at both ends of the test tube from the test tube. A second clamping component is set up. When the clamping cylinder clamps the test tube, the first clamping component moves upward and the second clamping component moves away from the first clamping component. The tube sleeves at both ends of the test tube are separated in this direction at the same time, making the overall operation more convenient.

[0010] Furthermore, the workbench is equipped with a turntable that rotates on the workbench. The rotation axis of the turntable is vertical. The outer circumference of the turntable is provided with clearance grooves. The opening of the clearance grooves faces away from the rotation axis of the turntable. Multiple clearance grooves are provided along the circumference of the turntable. The outer circumference of the turntable is also provided with an upper clamping groove and a lower clamping groove for inserting test tubes.

[0011] Through the above technical solution, a turntable is set up. In actual use, the outer wall of the turntable is provided with multiple clearance grooves. Each clearance groove corresponds to an upper clamping groove and a lower clamping groove. The test tubes are fixed by the upper clamping groove and the lower clamping groove. The clearance groove provides clearance space for the clamping cylinder. With this setting, multiple sets of test tubes and tube sleeves are separated in sequence, which improves the automation level of test tube and tube sleeve separation.

[0012] Furthermore, the turntable is provided with a mounting cavity, and the bottom of the upper clamping groove is provided with a sliding hole, the sliding hole communicating with the mounting cavity. A sliding rod slides through the sliding hole, and the sliding direction of the sliding rod is horizontal. The opening of the upper clamping groove is provided with a limiting hole, the limiting hole communicating with the mounting cavity. The mounting cavity is provided with a limiting member, and the sliding rod abuts against the limiting member. When the sliding rod moves towards the axis of the turntable, the sliding rod causes the limiting member to pass through the sliding hole and abut against the test tube.

[0013] By using the above technical solution, a sliding rod and a limiting component are set up. When the test tube is embedded in the clamping groove and moves towards the bottom of the clamping groove, the test tube abuts against the sliding rod, causing the sliding rod to move towards the axis of the turntable. The movement of the sliding rod pushes the limiting component to move, causing the limiting component to pass through the sliding hole and abut against the test tube, reducing the movement of the test tube in the vertical direction and making the overall use more stable.

[0014] Furthermore, the limiting component includes an arc-shaped block and a limiting spring. The sliding rod is connected to the sliding block, and the sliding block is located between the sliding rod and the arc-shaped block. The sliding block abuts against the arc surface of the arc-shaped block, and the arc-shaped block slides in the limiting hole. The elastic force of the limiting spring restricts the arc-shaped block from passing through the limiting hole.

[0015] Through the above technical solution, the arc-shaped block and the limiting spring are set. The arc-shaped block increases the contact area between the test tube and the sliding hole, reducing the possibility of the test tube moving in the vertical direction. Secondly, the limiting spring facilitates the movement of the test tube away from the turntable axis when the clamping cylinder is removed. The elastic force of the limiting spring indirectly causes the sliding rod to move away from the turntable axis, reducing the limitation of the limiting component on the horizontal movement of the test tube and facilitating the clamping cylinder to pick it up.

[0016] Furthermore, the arc-shaped block is provided with a first control rack, which is located at the end of the arc-shaped block away from the sliding rod. The mounting cavity is provided with a control assembly, which meshes with the first control rack. The mounting cavity is also provided with a second control rack, which meshes with the control assembly. When the sliding rod moves toward the axis of the turntable, the first control rack moves toward the axis of the turntable, and the second control rack moves upward. The turntable is provided with a release bar hole, which is located on the side wall of the turntable and extends through the turntable to the mounting cavity. The second control rack is provided with a control rod, which passes through the release bar hole and protrudes from the outer wall of the turntable. The control rod slides on the turntable in a vertical direction. The end of the control rod away from the control rack is provided with a release block, which slides on the control rod in a direction axial to the control rod. The release block is provided with a release spring, which restricts the release block from moving away from the second control rack.

[0017] The above technical solution uses a clamping cylinder to fix the test tube and clamping component one to separate the tube sleeve from the test tube. During the separation process, the clamping cylinder exerts pressure on the outer wall of the test tube, and the movement of clamping component one causes the test tube to tend to move upward. At this time, the clamping cylinder's grip on the outer wall of the test tube causes wear along the test tube's axis. Therefore, a loosening block and other components are set up. When the clamping cylinder moves the test tube away from the turntable axis, the elastic force of the limiting spring indirectly causes the sliding rod to move away from the turntable axis. The movement of the sliding rod causes control rack one to move away from the turntable axis and causes the control component to move control rack two upward. The upward movement of control rack two causes the loosening block to press against the tube sleeve and loosen the tube sleeve, making it easier for clamping component one to remove the tube sleeve, reducing wear on the outer wall of the test tube, and making the overall use more convenient.

[0018] Furthermore, the loosening block is provided with an inclined surface, which is located on the upper end face of the loosening block and extends upward along the direction close to the axis of the turntable.

[0019] The above technical solution involves setting an inclined surface one, which abuts against the sleeve, thereby loosening the sleeve while reducing damage from tightening and extending its service life.

[0020] Furthermore, the loosening block is provided with an inclined surface two, which is located on the lower end face of the loosening block. The inclined surface two extends downward along the direction close to the axis of the turntable, and the acute angle formed by the inclined surface two and the horizontal plane is greater than the acute angle formed by the inclined surface one and the horizontal plane.

[0021] Through the above technical solution, an inclined surface two is set. The setting of inclined surface two facilitates the sliding of the loosening block in conjunction with the loosening spring. Secondly, the acute angle formed by inclined surface two and the horizontal plane is set to be greater than the acute angle formed by inclined surface one and the horizontal plane. This makes it easier for the loosening block to move closer to the axis of the turntable when the control rack two moves down. This reduces the possibility of the tube sleeve and test tube becoming more tightly connected due to the downward movement of the loosening block, and makes the overall use more stable.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] (1) The test tube is clamped by the clamping cylinder. When separation is required, the clamping part 1 clamps the tube sleeve. Then the clamping part 1 is moved while the clamping cylinder is fixed. At this time, the movement of the clamping part 1 causes the tube sleeve to separate from the test tube. Separating the tube sleeve from the test tube in this way makes the overall operation more convenient and the sample injection operation simpler.

[0024] (2) By setting control rack two, control rack two to move upward so that the loosening block presses against the tube sleeve and plays a role in loosening the tube sleeve, making it easier for clamping part one to remove the tube sleeve, reducing the wear on the outer wall of the test tube, and making the overall use more convenient.

[0025] (3) By setting the acute angle between the second inclined surface and the horizontal plane to be greater than the acute angle between the first inclined surface and the horizontal plane, when the second control rack moves down, the second inclined surface makes it easier for the loosening block to move towards the axis of the turntable, reducing the situation where the loosening block moves down and the tube sleeve and test tube are more tightly connected, making the overall use more stable.

Detailed Implementation

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses an auxiliary sample introduction device for organic mass spectrometry detection.

[0033] Example:

[0034] Referring to Figure 1, an auxiliary sample introduction device for organic mass spectrometry detection includes a worktable 1, a turntable 2 on the upper surface of the worktable 1, the turntable 2 rotating on the worktable 1, and a drive component 3 and a clamping cylinder 4 located at the end of the turntable 2 away from the worktable 1. The drive component 3 drives the clamping cylinder 4 to move horizontally. In actual use, the worktable 1 is equipped with a motor, which drives the turntable 2 to rotate, and the rotation axis of the turntable 2 is vertical. The drive component 3 can be a hydraulic cylinder, or alternatively, a pneumatic cylinder.

[0035] The workbench 1 is equipped with a frame 5, located on its upper surface. The frame 5 has a clamping component 6, which slides vertically on the frame 5 and is used to clamp the pipe sleeve. The frame 5 also has a second clamping component 7, located on the side of the first clamping component 6 closest to the workbench 1. The second clamping component 7 slides on the frame 5 in the same direction as the first clamping component 6. In actual use, the frame 5 is also equipped with two cylinders: one for driving the first clamping component 6 to move vertically, and the other for driving the second clamping component 7 to move vertically. Both the first clamping component 6 and the second clamping component 7 are clamping cylinders 4.

[0036] Referring to Figures 1 and 2, the workbench 1 is equipped with a turntable 8 and a driving component 2. The turntable 8 rotates on the workbench 1, and the axis of rotation of the turntable 8 is vertical. The driving component 2 is used to drive the turntable 8 to rotate. The outer periphery of the turntable 8 is provided with relief grooves 9, and the opening of the relief grooves 9 faces away from the axis of rotation of the turntable 8. Multiple relief grooves 9 are provided along the circumference of the turntable 8. The outer periphery of the turntable 8 is also provided with an upper clamping groove 10 and a lower clamping groove 11. The upper clamping groove 10 is located above the lower clamping groove 11, and the upper clamping groove 10 and the lower clamping groove 11 are for inserting test tubes.

[0037] Referring to Figures 2 and 3, the turntable 8 has a mounting cavity 12, and the bottom of the upper clamping groove 10 has a sliding hole 13, which connects to the mounting cavity 12. A sliding rod 14 slides through the sliding hole 13 in a horizontal direction. A sliding block 15 is connected to one end of the sliding rod 14 near the turntable 8. The sliding rod 14 protrudes from the bottom of the upper clamping groove 10. The upper clamping groove 10 has a limiting hole 16 on its wall, located on the side of the upper clamping groove 10 away from the bottom. The limiting hole 16 connects to the mounting cavity 12. The mounting cavity 12 has a limiting element 17, and the sliding block 15 abuts against the limiting element 17. In actual use, the limiting element 17 includes an arc-shaped block 171 and a limiting spring 172. Both the arc-shaped block 171 and the limiting spring 172 are located within the mounting cavity 12. The arc-shaped block 171 slides in the limiting hole 16, and is used to pass through the limiting hole 16 and abut against the test tube. The side wall of the arc-shaped block 171 is provided with an abutment protrusion 18. The limiting spring 172 is connected to the arc-shaped block 171 by connecting to the abutment protrusion 18. The end of the limiting spring 172 away from the abutment protrusion 18 is connected to the cavity wall of the mounting cavity 12. The elastic force of the limiting spring 172 is used to limit the arc-shaped block 171 from passing through the limiting hole 16. In actual use, the limiting spring 172 also has the effect of limiting the movement of the sliding rod 14 towards the axis of the turntable 8.

[0038] When the sliding rod 14 moves toward the axis of the turntable 8, the movement of the sliding rod 14 causes the sliding block 15 to move. The movement of the sliding block 15 pushes the arc block 171 to move, so that the arc block 171 passes through the limiting hole 16 and presses against the test tube to restrict the movement of the test tube.

[0039] Referring to Figures 3 and 4, the arc-shaped block 171 is connected to a control rack 19, which is located at the end of the arc-shaped block 171 away from the sliding rod 14. The mounting cavity 12 is equipped with a control assembly 20, which meshes with the control rack 19 and controls the transmission of movement of the rack 19. The mounting cavity 12 is also equipped with a control rack 21, which slides against the wall of the mounting cavity 12 in a vertically opposite direction. The control rack 21 meshes with the control assembly 20. When the sliding rod 14 moves towards the axis of the turntable 8, the control rack 19 moves towards the axis of the turntable 8, and the control rack 203 moves upward.

[0040] In practical use, the control component 20 includes a first control gear 201, a first transmission wheel 202, a second control gear 203, and a second transmission wheel 204. The first control gear 201 is located above the first control rack 19 and meshes with the first control rack 19. The first transmission wheel 202 is coaxially arranged with the first control gear 201, and its diameter is larger than that of the second control gear 203. The first transmission wheel 202 is used to amplify the movement distance of the first control rack 19. The first transmission wheel 202 is belt-driven to the second transmission wheel 204, and the second transmission wheel 204 is coaxially connected to the second control gear 203. The diameter of the second control gear 203 is larger than that of the second transmission wheel 204. The second control gear 203 meshes with the second control rack 21 and is located at the end of the second control rack 21 near the axis of the turntable 8.

[0041] When the sliding rod 14 moves away from the axis of the turntable 8, the control rack 19 moves away from the axis of the turntable 8 and drives the control rack 21 to move upward through the control component 20.

[0042] The turntable 8 is provided with release strip holes 22, which are located on the side wall of the turntable 8. There are multiple release strip holes 22, and the number of release strip holes 22 is the same as that of the upper clamping groove 10, and their positions correspond one-to-one. The release strip holes 22 are located above the upper clamping groove 10, and the release strip holes 22 pass through the turntable 8 to the mounting cavity 12. The extension direction of the release strip holes 22 is vertical.

[0043] The control rack 21 is equipped with a control rod 23, which passes through the release bar hole 22 and protrudes from the outer wall of the turntable 8. The length direction of the control rod 23 is horizontal, and the control rod 23 slides on the turntable 8 in a vertical direction. A release block 24 is provided at the end of the control rod 23 away from the control rack. The release block 24 slides on the control rod 23 in a direction axial to the control rod 23. The release block 24 is equipped with a release spring 25, one end of which is connected to the release block 24, and the other end is connected to the control rack 21. The elastic force of the release spring 25 restricts the release block 24 from moving away from the control gear 203.

[0044] The release block 24 has an inclined surface 26, which is located on the upper end face of the release block 24 and on the side of the release block 24 away from the release spring 25. The inclined surface 26 extends upward along the direction close to the axis of the turntable 8 and is used to press against the tube sleeve to release the connection between the tube sleeve and the test tube. The release block 24 also has an inclined surface 27, which is located on the lower end face of the release block 24 and on the side of the release block 24 away from the release spring 25. The inclined surface 27 extends downward along the direction close to the axis of the turntable 8, and the acute angle formed by the inclined surface 27 and the horizontal plane is greater than the acute angle formed by the inclined surface 26 and the horizontal plane.

[0045] In actual use, the lower clamping groove 11 is also equipped with components such as control assembly 20 and control rack 21. These components are used to push the sleeve in the downward direction to loosen the sleeve.

[0046] The working principle of this embodiment is as follows:

[0047] In practical use, the test tube is embedded in the upper clamping groove 10 and the lower clamping groove 11. At this time, the inclined surface 26 of the release block 24 presses against the tube sleeve. When the clamping cylinder 4 moves the test tube away from the axis of the turntable 8, the elastic force of the limiting spring 172 causes the sliding rod 14 and the sliding block 15 to move away from the axis of the turntable 8. The movement of the sliding block 15 causes the control rack 19 to control the control gear 203 to move upward through the control component 20. The upward movement of the control gear 203 causes the inclined surface 26 of the release block 24 to press against the tube sleeve and push the tube sleeve to release.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
