Description

Technical Field

[0001] This invention relates to the field of pulse discharge detector technology, and in particular to an integrated insulating and sealed ion trap structure for a pulse discharge detector. Background Technology

[0002] The integrated insulated and sealed ion trap structure of the pulse discharge detector typically uses a sapphire tube as the core insulating component, combined with a metal slurry ring, a transverse sapphire tube, and a gold O-ring to achieve integrated sealing and electrode layout. The discharge zone and reaction zone are integrated within a hollow stainless steel cylindrical body. The discharge zone generates pulse discharge through a platinum-tipped discharge electrode mounted on a quartz cylindrical block. The reaction zone contains a bias electrode and a collection electrode. The electrodes are insulated by the sapphire tube and sealed by the gold O-ring. Simultaneously, the chromatographic column is introduced from the bottom and the carrier gas is introduced from the top, forming a closed ion capture space with coordinated gas and electrical circuits. This design balances insulation reliability, sealing stability, and ion capture efficiency, adapting to the ion generation and detection needs of detectors such as PDHID and PDECD.

[0003] Regarding the above and existing related technologies, the following defects are often found: In the actual use of pulse discharge detectors, when it is necessary to pull out the detection plug on the detector, the paddle on the surface of the detector plug is inconvenient to press, which reduces the docking efficiency of the detector plug.

[0004] Therefore, the present invention provides an integrated insulating and sealed ion trap structure for a pulse discharge detector. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the paddles on the detector plug surface are inconvenient to press and disconnect, and to propose an integrated insulating and sealed ion trap structure for a pulse discharge detector.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an integrated insulating and sealed ion trap structure for a pulse discharge detector, comprising a pulse discharge detector body, wherein a plurality of detection interfaces are provided on the surface of the pulse discharge detector body, and a detection plug is snapped into each of the plurality of detection interfaces; a limiting structure is provided on the surface of the pulse discharge detector body, the limiting structure comprising a support rod, the support rod being fixedly connected to the surface of the pulse discharge detector body; an adjusting plate being slidably connected to the arc surface of the support rod; a spring being sleeved on the arc surface of the support rod; the two ends of the spring being fixedly connected to the support rod and the adjusting plate respectively; and a plurality of pressure plates being fixedly connected to the surface of the adjusting plate.

[0007] The effect achieved by the above components is as follows: by setting a limiting structure, it is easy to press the tab on the surface of the detection plug, so that the operator can easily pull the detection plug out of the detection interface and quickly disconnect the detector.

[0008] Preferably, a round rod is fixedly connected to the side of the adjustment plate away from the pulse discharge detector body, and a round plate is rotatably connected to the end of the round rod away from the adjustment plate.

[0009] The effect achieved by the above components is as follows: the circular plate abuts against the end of the support rod away from the pulse discharge detector body, the pressure plate reaches the position of the limit adjustment plate, and thus limits the position of the pressure plate, which can prevent the detection plug from coming out of the detection interface due to accidental contact.

[0010] Preferably, a groove is provided on the side of the pressure plate away from the adjusting plate, and a pulley is rotatably connected to the inner wall of the groove.

[0011] The effect achieved by the above components is that when the detection plug moves, it drives the pulley to slide in the groove opened on the surface of the pressure plate, and the pulley reduces the friction between the pressure plate and the detection plug.

[0012] Preferably, the surface of the adjustment plate has two limiting rods that slide through it, and both limiting rods are fixedly connected to the surface of the pulse discharge detector body.

[0013] The effect achieved by the above components is that the adjusting plate will slide along the surface of the limiting plate when it moves, and the limiting rod will limit the movement path of the adjusting plate.

[0014] Preferably, the surface of the pulse discharge detector body is provided with a clamping structure, the clamping structure includes a slide rail, the slide rail is fixedly connected to the surface of the pulse discharge detector body, a bidirectional screw is rotatably connected to the inner wall of the slide rail, one end of the bidirectional screw passes through the slide rail, and two driving blocks are threadedly connected to the arc surface of the bidirectional screw, and a rectangular plate is fixedly connected to the surface of each of the two driving blocks.

[0015] The effect achieved by the above components is as follows: by setting up a clamping structure, it is easy to fix the pulse discharge detector body, thereby avoiding the need to support the pulse discharge detector body when unplugging the detector plug, which would otherwise make it inconvenient to quickly disconnect the detector.

[0016] Preferably, a plurality of anti-slip strips are fixedly connected to the side of each of the two rectangular plates that are close to each other, and the plurality of anti-slip strips are all rubber strips.

[0017] The effect achieved by the above components is that when the pressure plate is in contact with the object, it will cause the anti-slip strip to abut against the surface of the object. The anti-slip strip increases the friction between the pressure plate and the surface of the object, thereby preventing the pressure plate from detaching from the surface of the object.

[0018] Preferably, one end of the bidirectional screw is fixedly connected to a turntable, and the vertical cross section of the turntable is cross-shaped.

[0019] The effect achieved by the above components is that the rotation of the turntable will drive the bidirectional screw to rotate, and the turntable facilitates the rotation of the bidirectional screw.

[0020] In summary: 1. In this invention, by setting a limiting structure, the adjusting plate moves towards the pressure plate with the help of the spring tension. When the adjusting plate moves, it will drive the pressure plate to abut against the surface of the detection plug. The pressure plate will squeeze the lever, thereby facilitating the function of pressing the lever to disconnect the detector.

[0021] 2. In this invention, by setting a clamping structure, the rotation of the bidirectional screw will drive the two driving blocks to move closer to each other. When the driving blocks move, they will slide along the inner wall of the slide rail. When the driving blocks move, they will drive the pressure plate to move until the pressure plate is attached to the surface of the object, thereby limiting the pulse discharge detector body and preventing the pulse discharge detector body from being dragged when the detection plug is pulled out, thus facilitating the quick disconnection of the detector's function.

[0024] Reference Figure 1As shown, this invention provides a technical solution: an integrated insulated and sealed ion trap structure for a pulse discharge detector, comprising a pulse discharge detector body 1. The surface of the pulse discharge detector body 1 has several detection interfaces 2, each containing a detection plug 3. The surface of the pulse discharge detector body 1 has a limiting structure 4, which facilitates pressing the tabs on the surface of the detection plug 3, allowing the operator to easily pull the detection plug 3 out of the detection interface 2 and quickly disconnect the detector. The surface of the pulse discharge detector body 1 also has a clamping structure 5, which helps to fix the pulse discharge detector body 1 in place, preventing it from being dragged when the detector plug is pulled out, thus avoiding the need to support the pulse discharge detector body 1 when pulling out the detector plug and hindering the quick disconnection of the detector.

[0025] The following section will explain the specific design and function of its limiting structure 4 and clamping structure 5.

[0026] Reference Figures 2-4 As shown in this embodiment: the limiting structure 4 includes a support rod 41, which is fixedly connected to the surface of the pulse discharge detector body 1. An adjusting plate 42 is slidably connected to the arc surface of the support rod 41. A spring 43 is sleeved on the arc surface of the support rod 41. The two ends of the spring 43 are fixedly connected to the support rod 41 and the adjusting plate 42, respectively. Several pressure plates 44 are fixedly connected to the surface of the adjusting plate 42. A round rod 45 is fixedly connected to the side of the adjusting plate 42 away from the pulse discharge detector body 1. A round plate 46 is rotatably connected to the end of the round rod 45 away from the adjusting plate 42. The round plate 46 abuts against the end of the support rod 41 away from the pulse discharge detector body 1. The pressure plates 44 reach the position of the limiting adjusting plate 42, thereby limiting the position of the pressure plates 44 and preventing the detection plug 3 from being dislodged from the detection interface 2 due to accidental contact. A groove 47 is provided on the side of the pressure plate 44 away from the adjusting plate 42. A pulley 48 is rotatably connected to the inner wall of the groove 47. When the detection plug 3 moves, it drives the pulley 48 to slide within the groove 47 on the surface of the pressure plate 44. The pulley 48 reduces the friction between the pressure plate 44 and the detection plug 3. Two limiting rods 49 slide through the surface of the adjusting plate 42. Both limiting rods 49 are fixedly connected to the surface of the pulse discharge detector body 1. When the adjusting plate 42 moves, it slides along the surface of the limiting plate. The limiting rods 49 limit the movement path of the adjusting plate 42.

[0027] Reference Figures 1-2 and Figure 5As shown, specifically, the clamping structure 5 includes a slide rail 51, which is fixedly connected to the surface of the pulse discharge detector body 1. A bidirectional screw 52 is rotatably connected to the inner wall of the slide rail 51. One end of the bidirectional screw 52 passes through the slide rail 51, and two drive blocks 53 are threadedly connected to the arc surface of the bidirectional screw 52. Rectangular plates 54 are fixedly connected to the surfaces of the two drive blocks 53. Several anti-slip strips 55 are fixedly connected to the sides of the two rectangular plates 54 that are close to each other. The anti-slip strips 55 are all rubber strips. When the pressure plate 44 is in contact with the object, it will drive the anti-slip strips 55 to abut against the surface of the object. The anti-slip strips 55 increase the friction between the pressure plate 44 and the surface of the object, thereby preventing the pressure plate 44 from detaching from the surface of the object. A turntable 56 is fixedly connected to one end of the bidirectional screw 52. The vertical cross section of the turntable 56 is cross-shaped. The rotation of the turntable 56 will drive the bidirectional screw 52 to rotate, thus facilitating the rotation of the bidirectional screw 52.

[0028] Working principle: When the detector needs to be quickly disconnected, first rotate the circular plate 46. The rotation of the circular plate 46 will cause it to rotate with the circular rod 45. During rotation, the circular plate 46 will slide along the surface of the support rod 41. When the circular plate 46 disengages from the support rod 41, the adjusting plate 42 moves towards the pressure plate 44 under the tension of the spring 43. As the adjusting plate 42 moves, it will cause the pressure plate 44 to abut against the surface of the detection plug 3. The adjusting plate 42 will also slide along the surface of the limiting rod 49, thus limiting the movement path of the adjusting plate 42. Then, pull the detection plug 3. As the detection plug 3 moves, it will cause the sliding plate 45 to slide along the surface of the pressure plate 45. The pulley 48 slides within the groove 47 on the surface of the pressure plate 44. The pulley 48 reduces the friction between the pressure plate 44 and the detection plug 3. When the detection plug 3 is pulled out, the adjusting plate 42 is pulled. The movement of the adjusting plate 42 will compress the spring 43. At this time, the spring 43 is in a compressed state. Then, the circular plate 46 is rotated in the opposite direction until the circular plate 46 abuts against the end of the support rod 41 away from the pulse discharge detector body 1. The pressure plate 44 reaches the position of the limiting adjusting plate 42, thereby limiting the position of the pressure plate 44 and preventing the detection plug 3 from coming out of the detection interface 2 due to accidental contact.

[0029] When it is necessary to limit the pulse discharge detector body 1, first rotate the turntable 56. The rotation of the turntable 56 will drive the bidirectional screw 52 to rotate. The rotation of the bidirectional screw 52 will drive the two drive blocks 53 to move closer to each other. When the drive blocks 53 move, they will slide along the inner wall of the slide rail 51. When the drive blocks 53 move, they will drive the pressure plate 44 to move until the pressure plate 44 is in contact with the surface of the object, thereby limiting the pulse discharge detector body 1. When the pressure plate 44 is in contact with the object, it will drive the anti-slip strip 55 to abut against the surface of the object. The anti-slip strip 55 increases the friction between the pressure plate 44 and the surface of the object, thereby preventing the pressure plate 44 from detaching from the surface of the object.
