Description

Technical Field

[0001] This invention relates to the field of mass spectrometry technology, specifically to a mass spectrometer that prevents the wire bundle from detaching under stress. Background Technology

[0002] For example, in a mass spectrometer with publication number CN210171510U, the main body of the mass spectrometer is fixedly connected to the main body fixing frame of the mass spectrometer, and the main body fixing frame of the mass spectrometer is fixedly connected to the operating table of the mass spectrometer. The main body of the mass spectrometer is fixed to the operating table of the mass spectrometer by bolts and nuts, and the gap between the main body of the mass spectrometer and the operating table is reduced by springs and elastic plates, so that the main body of the mass spectrometer and the operating table are more tightly fixed. For example, a high-performance liquid chromatography-mass spectrometer with multiple detection stations disclosed in CN217007142U has a lifting mechanism installed on each baffle, and a moving mechanism linked to the lifting mechanism is provided at the corresponding position. The moving mechanism is installed on the mass spectrometer housing. Several sliding grooves are opened at the bottom of the mass spectrometer housing, and through grooves and top grooves are opened at the top of the mass spectrometer housing. Several positioning holes are opened at the top of the mass spectrometer housing. Through the set moving mechanism, samples at multiple detection stations can be detected sequentially. In the process of mass spectrometry detection, an essential step is to connect the detection equipment's circuitry. However, the conventional plug-in structure has certain limitations. If the detection circuitry of the mass spectrometer becomes loose or detached due to external forces, the experimental data cannot be saved, posing a significant safety hazard and substantially affecting subsequent experimental results, thus limiting its usability.

[0003] To address the aforementioned issues, there is an urgent need for innovative design based on the existing mass spectrometer structure. Summary of the Invention

[0004] The purpose of this invention is to provide a mass spectrometer that avoids wire harness detachment under stress, thereby solving the problem that the ordinary plug-in structure mentioned in the background art has certain limitations. When the detection line of the mass spectrometer becomes loose or detached due to external force, the experimental data cannot be saved, which poses a significant safety hazard and has a substantial impact on subsequent experimental results.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mass spectrometer that prevents wire bundle from falling off under stress, comprising a mass spectrometer body, wherein a reserved insertion end is provided on the outer side of the mass spectrometer body, and a first docking airbag assembly is bonded to the inner surface of the reserved insertion end. A reserved guide block is nested inside the reserved plug end, and the reserved guide block is connected to the inner end of the mass spectrometer body. A reset spring is fixedly connected to the rear end of the reserved guide block to form a reset structure. A contact switch is fixedly connected to both the outer side of the reserved guide block and the inner end of the mass spectrometer body. A positioning auxiliary component is nested on the outside of the mass spectrometer body, and a first traction docking rope is fixedly connected to the outside of the positioning auxiliary component. The first traction docking rope extends along the inside of the mass spectrometer body, and the end of the first traction docking rope docks with the outside of the reserved guide block. A first magnet is fixedly connected to the outside of the positioning auxiliary component. The mass spectrometer body has a guide groove at its inner end, and a movable connector is nested inside the guide groove. The movable connector is located inside the mass spectrometer body, and a connecting shaft assembly is installed through the outer side of the movable connector. Electromagnet assemblies are fixedly connected to both the outer side of the movable connector and the inner side of the guide groove. The outer side of the shaft end of the connecting shaft assembly is wound with a second traction docking rope, and the end of the second traction docking rope is docked with the inner side of the mass spectrometer body. The surface of the mass spectrometer body is provided with a reserved accommodating through hole, and the guide groove, movable connector, connecting shaft assembly and electromagnet assembly are all located inside the reserved accommodating through hole.

[0006] Furthermore, the first docking airbag assembly is provided with a gas delivery hose and a second docking airbag assembly, and a gas delivery hose is installed through the outer side of the first docking airbag assembly, and the end of the gas delivery hose is docked with the second docking airbag assembly. At the same time, the second docking airbag assembly is docked with the inner side of the mass spectrometer body, and the outer position of the second docking airbag assembly corresponds to that of the positioning auxiliary component.

[0007] Furthermore, the first docking airbag assembly is angularly distributed about the center point of the mass spectrometer body, and the first docking airbag assembly forms an airflow conduction structure through the gas supply hose and the second docking airbag assembly. When the positioning auxiliary component is pressed inward, it creates a negative pressure state on the second docking airbag assembly, so that when the positioning auxiliary component is pressed inward, pressure can be applied through the second docking airbag assembly, and then gas can be supplied to the inside of the first docking airbag assembly through the gas supply hose.

[0008] Furthermore, when the reserved guide block contacts the external connector, it moves inward under force, and the reserved guide block, together with the reset spring, forms a reset state along the inner side of the mass spectrometer body. In addition, the reserved guide block forms an electrical connection with the contact switch inside the mass spectrometer body through the contact switch.

[0009] Furthermore, the positioning auxiliary components are symmetrically distributed about the center point of the mass spectrometer body, and the positioning auxiliary components are in a traction state with the reserved guide block through the first traction docking rope. The positioning auxiliary components are in an attractive state through the first magnet on the outside, so that the two positioning auxiliary components that are close to each other can stably cooperate with the multiple first magnets on the outside to position each other.

[0010] Furthermore, the movable connector forms a sliding structure along the inner side of the mass spectrometer body via a guide groove, and the movable connector is normally located on the inner side of the mass spectrometer body.

[0011] Furthermore, the connecting shaft assembly is provided with a secondary positioning component and a second magnet component, and the secondary positioning component is fixedly connected to the outer side of the lower end of the connecting shaft assembly, and the second magnet component is fixedly connected to the outer side of the secondary positioning component. At the same time, a torsion spring assembly is nested between the connecting shaft assembly and the movable connecting component.

[0012] Furthermore, during the outward movement of the movable connector under force, the connecting shaft assembly and the secondary positioning component will be driven inward to form a rotating structure by the relatively stationary second traction docking rope. The secondary positioning component will also be attracted to each other by the second magnet on the outside, allowing the electromagnet assembly in the powered state to push the movable connector outward through its repulsive force. The connecting shaft assembly and the secondary positioning component will be driven inward to form a rotating structure by the relatively stationary second traction docking rope.

[0013] Furthermore, the electromagnet assembly on the outer side of the movable connector and the inner side of the guide groove have the same magnetic poles, and the power supply state of the electromagnet assembly is electrically connected through the contact state between the contact switches.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This mass spectrometer, designed to prevent wire harness detachment under stress, is equipped with symmetrically distributed positioning aids. As the external connector is inserted into the pre-installed connector end, the corresponding inwardly moving guide block will work in conjunction with the traction rope to bring the two positioning aids closer together, achieving a self-limiting working state for the outer side of the connector. This avoids the limitations of ordinary plug-in structures. External forces will not cause the detection circuit of the mass spectrometer to become loose or detached, maximizing the preservation of experimental data and preventing substantial impact on subsequent experimental results. 2. The mass spectrometer that prevents the wire harness from falling off under force is equipped with an adaptive first docking gasbag assembly. As the positioning auxiliary parts are subjected to force and move closer together, the second docking gasbag assembly that contacts its inner end will be compressed accordingly. Then, gas is supplied to the inside of the annular first docking gasbag assembly through the gas supply hose, causing it to expand and adaptively position the outside of the contact plug, preventing it from easily falling off and improving the practicality of the device. 3. This mass spectrometer, designed to prevent wire harness detachment under stress, is equipped with a self-moving movable connector. During the inward movement of the two pre-reserved guide blocks under stress, the pre-reserved guide blocks that are in contact with each other and the contact switch inside the mass spectrometer body form an electrical connection. This allows the electromagnet assembly in the powered state to push the movable connector outward through its repulsive force. The second traction docking rope, which is relatively stationary, drives the connecting shaft assembly and the secondary positioning component to rotate inward, thereby cooperating with the two secondary positioning components that are in contact to perform a secondary locking process on the outside of the positioning auxiliary component, improving the overall setup effect.

A reset spring 5 is fixedly connected to the rear end of the reserved guide block 4 to form a reset structure. A contact switch 6 is fixedly connected to both the outer side of the reserved guide block 4 and the inner end of the mass spectrometer body 1. A positioning auxiliary component 8 is nested on the outside of the mass spectrometer body 1, and a first traction docking rope 7 is fixedly connected to the outside of the positioning auxiliary component 8. The first traction docking rope 7 extends along the inside of the mass spectrometer body 1, and the end of the first traction docking rope 7 docks with the outside of the reserved guide block 4. A first magnet 9 is fixedly connected to the outside of the positioning auxiliary component 8. The mass spectrometer body 1 has a guide groove 10 at its inner end, and a movable connector 11 is nested inside the guide groove 10. The movable connector 11 is located inside the mass spectrometer body 1, and a connecting shaft assembly 12 is installed through the outer side of the movable connector 11. An electromagnet assembly 13 is fixedly connected to both the outer side of the movable connector 11 and the inner side of the guide groove 10. A second traction docking rope 14 is wound around the outer side of the shaft end of the connecting shaft assembly 12, and the end of the second traction docking rope 14 is docked with the inner side of the mass spectrometer body 1.

[0020] The first docking airbag assembly 3 is provided with a gas delivery hose 301 and a second docking airbag assembly 302. The gas delivery hose 301 is installed through the outer side of the first docking airbag assembly 3, and the end of the gas delivery hose 301 is docked with the second docking airbag assembly 302. The second docking airbag assembly 302 is docked with the inner side of the mass spectrometer body 1, and the outer side of the second docking airbag assembly 302 corresponds to the outer side of the positioning auxiliary component 8. The first docking airbag assembly 3 is angularly distributed about the center point of the mass spectrometer body 1, and the first docking airbag assembly 3 forms an airflow conduction structure through the gas delivery hose 301 and the second docking airbag assembly 302. When the positioning auxiliary component 8 is pressed inward, it creates a negative pressure state on the second docking airbag assembly 302. When the reserved guide block 4 contacts the external connector, it moves inward under force, and the reserved guide block 4, together with the reset spring 5, forms a reset state along the inner side of the mass spectrometer body 1. The reserved guide block 4 is electrically connected to the contact switch 6 on the inner side of the mass spectrometer body 1 through the contact switch 6.

[0021] When the external plug needs to be connected to the reserved plug end 2, the corresponding inwardly moving reserved guide block 4 will cooperate with the first traction docking rope 7 to drive the two positioning auxiliary parts 8 to move closer together and cooperate with the first magnet 9 for positioning, realizing the self-limiting working state of the plug's outer side. This avoids the limitations of ordinary plug-in structures. Due to the influence of external forces, the detection circuit of the mass spectrometer will not become loose or fall off, thus maximizing the preservation of experimental data. During the process of the positioning auxiliary parts 8 moving closer together under force, the second docking airbag assembly 302, which is in contact with its inner end, will be compressed. Then, air will be supplied to the annular first docking airbag assembly 3 through the gas supply hose 301, causing it to expand and perform adaptive positioning treatment on the outer side of the contacting plug, preventing it from easily falling off and improving the practicality of the device.

A torsion spring assembly is nested between the connecting shaft assembly 12 and the movable connector 11. During the outward movement of the movable connector 11 under force, the second traction docking rope 14, which remains stationary relative to it, drives the connecting shaft assembly 12 and the secondary positioning component 1201 to rotate inward, and the secondary positioning component 1201, through the outer second magnet component 1202, forms an attractive state with itself. The electromagnet assembly 13 on the outer side of the movable connector 11 and the inner side of the guide slide 10 have the same magnetic poles, and the power supply state of the electromagnet assembly 13 is electrically connected through the contact state between the contact switches 6.

[0023] During the process of the two reserved guide blocks 4 moving inward under force, the reserved guide blocks 4 that are in contact with each other and the contact switch 6 on the inner side of the mass spectrometer body 1 will form an electrical connection state, allowing the electromagnet assembly 13 in the power supply state to push the movable connector 11 outward through its repulsive force, and through the second traction docking rope 14 that is relatively stationary, drive the connecting shaft assembly 12 and the secondary positioning component 1201 to form a rotating structure inward, thereby cooperating with the second magnet 1202 to allow the two secondary positioning components 1201 that are in contact to perform a secondary locking process on the outer side of the positioning auxiliary component 8 that is in contact with their inner ends, thereby improving the practicality of the device.
