Description

Technical Field

[0001] This utility model belongs to the field of gas cylinder sealing detection technology, and in particular relates to an industrial gas cylinder sealing detection device. Background Technology

[0002] Gas cylinder seal testing is a crucial step in ensuring the safe use of gas cylinders. Employing appropriate testing methods can effectively prevent the risks associated with gas cylinder leaks. Different methods are suitable for different types of gas cylinders and leak detection requirements; therefore, selecting the right testing technology is of paramount importance.

[0003] According to a public announcement (Announcement No.: CN221959707U), a gas cylinder sealing performance testing device includes a gas cylinder body and a sealing shell. The sealing shell has an outlet on its side and a flexible tube connected to its bottom. The flexible tube is fitted onto the outer wall of the gas cylinder body, and a clamp unit is provided on the outside of the flexible tube. The flexible tube is securely sealed to the outer wall of the gas cylinder body through the clamp unit. This invention allows the clamp body to tighten by rotating the rotating part of the bolt head, thereby securing the flexible tube to the outer wall of the gas cylinder body and preventing air leakage at the junction of the flexible tube and the outer wall of the gas cylinder body, which would affect the gas cylinder's sealing performance. The testing method is intuitive; whether the gas cylinder is leaking can be quickly determined by observing whether the balloon inflates, or by blocking the outlet with a plug and observing the change in the pressure count value to determine the gas cylinder's sealing performance. The testing efficiency is high, requiring no movement of the gas cylinder, avoiding collisions and damage, and eliminating the need for filling and venting the gas cylinder, resulting in low energy consumption and low cost.

[0004] The aforementioned patent achieves high detection efficiency through the cooperation of components such as the gas cylinder body and the sealing shell, without the need to move the gas cylinder, thus avoiding collisions and damage. It also eliminates the need to vent the gas cylinder after filling it, resulting in low energy consumption and low cost. However, it cannot effectively achieve the rapid, convenient replacement and secure locking of the industrial gas cylinder testing connector, significantly improving the replacement efficiency and solving the problems of cumbersome and leak-prone connector replacement in traditional testing devices. Therefore, we propose an industrial gas cylinder sealing detection device. Utility Model Content

[0005] The purpose of this invention is to provide an industrial gas cylinder sealing test device, which solves the problems of cumbersome connector replacement and easy leakage in traditional test devices by using a convenient multi-specification connector replacement device.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is an industrial gas cylinder sealing test device, including a base, an operating table fixedly connected to the top of the base, a touch screen and control buttons on the side of the operating table, an airtightness data display panel on the side of the operating table, a test connection tube on the side of the base, a rigid connection tube fixedly connected to one end of the test connection tube, and a multi-specification connector for easy replacement on the inner side of the rigid connection tube.

[0008] The convenient multi-specification connector replacement device includes a groove formed on the inner side of a rigid connecting tube. A compression spring is fixedly connected to the inner side of the groove. A locking pin is fixedly connected to one end of the compression spring, and a connecting rod is fixedly connected to one end of the locking pin. A connector is slidably connected to the inner side of the rigid connecting tube, and a retaining groove is formed on the circumferential surface of the connector. The main function of this convenient multi-specification connector replacement device is to enable quick and convenient disassembly and reassembly of the rigid connecting tube and the connector, while ensuring the stability and airtightness of the connector, and adapting to various connector specifications.

[0009] Furthermore, one end of the connecting rod penetrates the side of the rigid connecting tube. The connecting rod penetrating the side of the rigid connecting tube serves to fix, support, guide, and stabilize the device. This enhances the stability and sealing of the device, and also makes the connector easier to disassemble and replace, improving the device's convenience and durability.

[0010] Furthermore, the connecting rod is slidably connected to the rigid connecting tube through the portion. The slidable connection design of the connecting rod primarily provides flexibility, adjustability, adaptability, and convenience.

[0011] Furthermore, the inner surface of the slot is located on the displacement trajectory of the locking post, and the diameter of the slot is the same as the diameter of the locking post. This design is intended to securely lock the connector to the rigid connecting tube through the cooperation of the locking post and the slot.

[0012] Furthermore, a replacement ejection device is provided on the inner side of the rigid connecting tube. The replacement ejection device includes a circular groove formed on the inner side of the rigid connecting tube. A return spring is fixedly connected to the inner side of the circular groove, and a circular push plate is fixedly connected to one end of the return spring. The function of this replacement ejection device is to make component replacement more convenient through its automatic ejection design, improve the automation level of the operation, reduce the need for manual intervention, and ensure the stability of the components.

[0013] Furthermore, the circumferential surface of the circular push plate is slidably connected to the inner surface of the circular groove, and the center of the circular push plate is hollowed out. This design is to prevent the circular push plate from interfering with the operation of the airtightness testing device.

[0014] Furthermore, one end of the connector is positioned on the displacement trajectory of the circular push plate. This design enables the connector to be pushed out and replaced effectively and accurately.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, through the cooperation of components such as locking posts and compression springs, achieves rapid, convenient replacement and secure locking of industrial gas cylinder testing connectors, significantly improving replacement efficiency. This design effectively solves the problems of cumbersome connector replacement and easy leakage in traditional testing devices, adapts to the testing needs of various gas cylinder specifications, and improves the versatility and ease of operation of the testing device.

[0017] 2. This utility model simplifies the operation process and improves the automation level of testing by using components such as a return spring and a circular push plate in cooperation. The replacement ejection device includes a circular slide, a return spring, and a circular push plate. The circular push plate adopts a hollow structure to ensure that it does not interfere with gas flow during the airtightness test, while its sliding connection design ensures a smooth ejection action. When the connector is disassembled, the return spring automatically releases its elastic force, pushing the circular push plate to accurately push the connector out, reducing manual intervention and avoiding problems such as connector jamming or difficulty in removal. This reduces the difficulty of operation and time costs, and enhances the reliability of the equipment and the user experience.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 As shown, this utility model is an industrial gas cylinder sealing test device, including a base 1, an operating table 2 fixedly connected to the top of the base 1, a touch screen 3 on the side of the operating table 2, an adjustment button 4 on the side of the operating table 2, an airtight data display panel 5 on the side of the operating table 2, a test connection tube 6 on the side of the base 1, a rigid connection tube 7 fixedly connected to one end of the test connection tube 6, and a multi-specification connector easy replacement device 8 on the inner side of the rigid connection tube 7.

[0029] The multi-specification connector easy-to-change device 8 includes a groove 81, which is formed on the inner side of the rigid connecting tube 7. A compression spring 82 is fixedly connected to the inner side of the groove 81. A retaining post 83 is fixedly connected to one end of the compression spring 82, and a connecting rod 84 is fixedly connected to one end of the retaining post 83. A connector 85 is slidably connected to the inner side of the rigid connecting tube 7, and a retaining groove 86 is formed on the circumferential surface of the connector 85. The main function of this multi-specification connector easy-to-change device 8 is to enable quick and convenient disassembly and reassembly between the rigid connecting tube 7 and the connector 85, while ensuring the stability and airtightness of the connector 85, and adapting to the effect of connectors 85 of various specifications.

[0030] One end of the connecting rod 84 passes through the side of the rigid connecting tube 7. The connecting rod 84, passing through the side of the rigid connecting tube 7, serves to fix, support, guide, and stabilize the device. This enhances the stability and sealing of the device, and also makes the connector 85 easier to disassemble and replace, improving the device's convenience and durability.

[0031] The connecting rod 84 is slidably connected to the rigid connecting tube 7 through the part. The slidable connection design of the connecting rod 84 is mainly to provide flexibility, adjustability, adaptability, and convenience.

[0032] The inner side of the slot 86 is located on the displacement trajectory of the pin 83, and the diameter of the slot 86 is the same as the diameter of the pin 83. This design is intended to securely lock the connector 85 to the rigid connecting tube 7 through the cooperation of the pin 83 and the slot 86.

[0033] The rigid connecting tube 7 has a replacement ejection device 9 on its inner side. The replacement ejection device 9 includes a circular slide groove 91, which is formed on the inner side of the rigid connecting tube 7. A return spring 92 is fixedly connected to the inner side of the circular slide groove 91, and a circular push plate 93 is fixedly connected to one end of the return spring 92. The function of this replacement ejection device 9 is to make component replacement more convenient through its automatic ejection design, improve the automation level of the operation, reduce the need for manual intervention, and ensure the stability of the components.

[0034] The circumferential surface of the circular push plate 93 is slidably connected to the inner side of the circular groove 91, and the center of the circular push plate 93 is hollow. This design is to prevent the circular push plate 93 from interfering with the operation of the airtightness testing device.

[0035] One end of the connector 85 is located on the displacement trajectory of the circular push plate 93. This design enables the connector 85 to be pushed out and replaced effectively and accurately.

[0036] A specific application of this embodiment is as follows: Based on the interface specifications of the industrial gas cylinder to be tested, a suitable connector 85 of various sizes is selected. The selected connector 85 is inserted into the inner side of the rigid connecting tube 7. During insertion, the end of the connector 85 contacts the circular push plate 93 and applies pressure, causing the circular push plate 93 to slide inward along the circular groove 91, compressing the return spring 92. When the connector 85 is fully inserted, the slot 86 on its circumferential surface aligns with the locking post 83. Under the elastic force of the compression spring 82, the locking post 83 automatically engages in the slot 86, producing a "click" sound to indicate that locking is complete. At this point, the connector 85 is securely fixed, tightly connecting the rigid connecting tube 7 with the connector 85 installed to the gas cylinder interface, ensuring no leakage. The detection parameters are set via the touch screen 3 on the operating console 2, and the detection program is started via the control button 4. The detection connecting tube 6 fills the gas cylinder with detection gas, and the system monitors the internal pressure changes of the gas cylinder in real time. The airtightness data display panel 5 dynamically displays data such as pressure value and leakage rate. After the test is completed, first disconnect the gas cylinder from the connector 85. If it is necessary to replace the connector 85 to test a gas cylinder of another specification, pull the connecting rod 84 outward. The connecting rod 84 drives the locking pin 83 to disengage from the locking groove 86, thus releasing the lock. At the same time, the return spring 92 pushes the circular push plate 93 outward, automatically ejecting the connector 85 from the rigid connecting tube 7, achieving quick disassembly.
