Abstract

This utility model relates to the field of sample inlet connectors and discloses a sample inlet connector suitable for multi-diameter gas bags. The connector includes an internal anti-leakage mechanism and an external disassembly mechanism. A sealing ring is also internally fixedly connected to the connector. The anti-leakage mechanism includes a valve core, which is externally slidably connected to the inside of the connector. An elastic component is fixedly connected to the right side of the valve core, and a support base is fixedly connected to the right side of the elastic component. In this utility model, the valve core slides due to gas thrust, causing a spring to deform and allowing gas to enter.

Description

Technical Field

[0001] This utility model relates to the field of sample inlet connectors, and more particularly to a sample inlet connector suitable for multi-diameter gas bags. Background Technology

[0002] The multi-caliber compatibility means that the connector can be compatible with gas bag interfaces of different sizes and specifications through a specific mechanical structure. The gas bag injection connector is a connecting component that connects the gas bag, realizes the stable delivery of gas samples inside the gas bag, prevents gas leakage and the infiltration of external impurities, and ensures the accuracy of injection.

[0003] Existing technologies are partially applicable to gas bag injection connectors with multi-diameter diameters. The internal channel flow direction detection equipment of the gas-to-gas connector enables gas delivery. The sealing ring increases the sealing performance against gas leakage, and the multi-diameter docking module adapts to gas bag interfaces of different sizes.

[0004] In the existing technology, some gas bag injection connectors are applicable to multiple diameters. However, during the gas injection process, when the gas pressure inside the gas bag fluctuates, it is difficult for a single sealing ring to maintain a tight fit with the valve core and the inner wall of the connector. Gas is prone to leak from the gap between the sealing ring and the components. Therefore, a gas bag injection connector applicable to multiple diameters is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a gas bag injection connector suitable for multiple diameters, aiming to improve the problem that some existing gas bag injection connectors suitable for multiple diameters are difficult to prevent gap leakage when there is a lack of gas fluctuation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A gas bag injection connector suitable for multiple calibers includes a connector, an internal anti-leakage mechanism fixedly connected to the connector, an external disassembly mechanism fixedly connected to the connector, and a sealing ring fixedly connected to the internal part of the connector.

[0008] The leak prevention mechanism includes a valve core, the outside of which is slidably connected to the inside of the connector, an elastic component is fixedly connected to the right side of the valve core, and a support seat is fixedly connected to the right side of the elastic component.

[0009] As a further description of the above technical solution:

[0010] The elastic component includes a spring, the left side of which is fixedly connected to the right side of the valve core, and a limit plate is fixedly connected to the right side of the spring.

[0011] As a further description of the above technical solution:

[0012] The disassembly mechanism includes a retaining ring, the inside of which is fixedly connected to the outside of the connector, and a retaining ring is slidably connected to the outside of the retaining ring.

[0013] As a further description of the above technical solution:

[0014] The fixed ring is externally fixedly connected to a limiting ring one, and a spring two is fixedly connected to the right side of the limiting ring one;

[0015] As a further description of the above technical solution:

[0016] The spring 2 is externally slidably connected to a sliding ring, and the sliding ring is internally fixedly connected to a limit ring 2;

[0017] As a further description of the above technical solution:

[0018] The fixed ring has a sliding bead inside, and the limiting ring II has a sliding connection to the outside of the fixed ring.

[0019] As a further description of the above technical solution:

[0020] The elastic component is externally slidably connected to the inside of the joint, and the support base is externally fixedly connected to the inside of the joint.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the valve core is driven to slide by the gas thrust, causing the spring to deform and allowing gas to enter. When the gas intake at the interface stops, the spring's deformation recovery force, under the limiting support of the limiting plate and the support seat, drives the valve core to slide and lock the inside of the connector, and the gas inside the connector is leaked through the sealing ring.

[0023] 2. In this utility model, by manually sliding the sliding ring, the sliding ring drives the limiting ring two to compress the spring two and deform it. The limiting ring one fixes and supports the spring two, so that the sliding ball inside the fixed ring slides outward, and the docking structure inside the fixed ring can be slidably disassembled.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] A sample inlet connector suitable for multi-caliber gas bags, as shown in the reference. Figure 1 and Figure 2 The device includes a connector 1 with an internal through-flow gas passage. The connector 1 is internally fixedly connected to an anti-leakage mechanism 2 to ensure that there is no leakage or backflow during the gas delivery process. The connector 1 is externally fixedly connected to a disassembly mechanism 3 to enable quick docking and disassembly of the gas bag and the connector 1, adapting to the clamping requirements of gas bags of different diameters. The connector 1 is internally fixedly connected to a sealing ring 4. The gas passage inside the connector 1 is spaced to achieve gas sealing.

[0032] Specifically, the valve core 21 of the anti-leakage mechanism 2 slides with the gas thrust to open the gas path and is sealed by the spring reset. The sliding ring 35 of the disassembly mechanism 3 slides to drive the sliding ball 37 to disassemble and adapt to different gas bags. The sealing ring 4 always fits the gap between the components, so that the gas delivery is leak-free and backflow-free, improving the efficiency and accuracy of sample injection.

[0033] The leak prevention mechanism 2 includes a valve core 21, which is externally slidably connected to the inside of the connector 1. The valve core 21 is the structure in the leak prevention mechanism 2 that controls the opening and closing of the gas path. An elastic component 22 is fixedly connected to the right side of the valve core 21. The elastic component 22 provides power support for the sliding and resetting of the valve core 21. A support seat 23 is fixedly connected to the right side of the elastic component 22, which serves as the installation reference and limit for the elastic component 22. The elastic component 22 includes a spring 221. When the valve core 21 slides under the thrust of gas, the spring 221 is compressed to generate deformation and store elastic power. The left side of the spring 221 is fixedly connected to the right side of the valve core 21. A limit plate 222 is fixedly connected to the right side of the spring 221 to limit the sliding position of the spring 221.

[0034] Specifically, the valve core 21 slides along the connector 1 under the thrust of the gas to open the gas path, compresses the spring 221 to deform and store energy, the support seat 23 limits the position of the elastic component 22, the limiting plate 222 fixes the position of the spring 221, and after the gas thrust disappears, the spring 221 releases its force to drive the valve core 21 to reset and block the gas path, realizing automatic opening and closing of the gas path, preventing leakage and eliminating the need for manual adjustment, thus improving the stability of sample injection.

[0035] Reference Figure 3 and Figure 4 The disassembly mechanism 3 includes a fixing ring 31, which is fixedly connected to the outside of the connector 1. The fixing ring 31 is the bearing structure of the disassembly mechanism 3 for adapting to multi-diameter air bags. The fixing ring 31 is slidably connected to a fixing ring 32, which slides on the fixing ring 31. The fixing ring 32 is fixedly connected to the left side of a limiting ring 33 and a limiting spring 34. The limiting ring 33 is fixedly connected to the right side of a spring 34, which is the power source for elastic clamping and automatic reset. The spring 34 is slidably connected to a sliding ring 35, which is the operating component for controlling the sliding bead 37 to slide. The sliding ring 35 is fixedly connected to the right side of a limiting ring 36, which limits the right side of a spring 34. The fixing ring 31 is slidably connected to a sliding bead 37, which fits tightly against the outer wall of the air bag interface.

[0036] Specifically, the sliding ring 35 slides and compresses and releases the second spring 34, causing the fixed ring 32 to slide against the fixed ring 31. The sliding ring 35 controls the sliding bead 37 to slide so that the outside fits the air bag interface. The second spring 34 resets and pushes the sliding ring 35, so that the sliding bead 37 clamps the air bag, realizing the quick disassembly and assembly and stable clamping of multi-diameter air bags, improving adaptability and operating efficiency.

[0037] Reference Figure 1 and Figure 2 , Figure 4The inner sliding connection of the second limiting ring 36 is to the outside of the fixed ring 32. The second limiting ring 36 evenly transmits the thrust of the sliding ring 35 to the second spring 34, avoiding uneven force on the second spring 34 and deformation displacement. The outer sliding connection of the elastic component 22 is to the inside of the connector 1, ensuring that the elastic component 22 and the valve core 21 will not deviate during movement. The outer fixed connection of the support seat 23 is to the inside of the connector 1, preventing the valve core 21 from slipping out of the air passage due to excessive sliding.

[0038] Specifically, the limiting ring 36 and the sliding ring 35 slide against the fixed ring 32, transmitting the thrust evenly to the spring 34 to prevent deformation from causing deviation. The elastic component 22 and the valve core 21 slide smoothly inside the joint 1. The support seat 23 is fixed inside the joint 1 to limit the sliding trajectory of the valve core 21, ensuring the stable movement of the spring 34 and the valve core 21 and improving the reliability of the mechanism operation.

[0039] The implementation principle of this application embodiment is as follows: the gas pushes the valve core 21, causing the spring 221 to be compressed and deformed by the thrust. The limiting plate 222 limits the spring 221 inside the connector 1, and the support seat 23 fixes it inside the connector 1, thus supporting the sliding movement of the valve core 21 and the elastic component 22. When no more gas enters the interface, the restoring force of the compressed deformation of the spring 221, supported by the limiting plate 222 and the support seat 23, slides the valve core 21, causing the valve core 21 to be locked inside the connector 1. Multiple sealing rings 4 are provided inside the connector 1 to prevent the gas from leaking.

[0040] By manually sliding the sliding ring 35, the sliding ring 35 drives the second limiting ring 36 to compress the second spring 34, causing the second spring 34 to deform. The first limiting ring 33 is fixed to the outside of the fixed ring 32, providing limiting support for the second spring 34. By sliding the sliding ring 35, the sliding bead 37 inside the fixed ring 31 slides. When the sliding bead 37 slides outward, the docking structure inside the fixed ring 31 slides and disassembles. The compression deformation of the second spring 34 provides restoring power, which drives the sliding ring 35 to slide against the fixed ring 31, causing the fixed ring 32 to slide and compress the sliding bead 37 inside the fixed ring 31, causing the sliding bead 37 to slide and thus locking the docking structure inside the fixed ring 31.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
