Description

Technical Field

[0001] This utility model relates to the field of gas supply equipment, specifically to a gas supply component. Background Technology

[0002] Gas supply equipment generally includes a gas supply end and a gas source, and a gas supply pipe is usually installed between the two.

[0003] Gas supply equipment is used in all aspects of production and daily life, such as providing oxygen to patients in hospitals, mining workers when they explore underground veins, and divers when they dive.

[0004] However, existing gas supply equipment is too large and inconvenient to store. Its integrated design makes it difficult to access and is heavy, making it difficult to maintain later. This results in a long setup time when gas supply equipment is needed, and there is a risk of untimely gas supply. Utility Model Content

[0005] To address the inconvenience and maintenance difficulties caused by the integrated design of gas supply equipment, a gas supply component is provided:

[0006] A gas supply component adopts the following technical solution:

[0007] A gas supply assembly includes a gas supply pipe, with a first connector and a second connector respectively provided at both ends of the gas supply pipe. The first connector includes a first conduit and a first insertion tube connected by a threaded connection. The first conduit is connected to the gas supply pipe through a first connecting ring. The outer surface of the first connecting ring is provided with at least one protrusion.

[0008] The second connector includes a second conduit and a second insertion tube. A connecting rod passes through the second conduit, with both ends of the connecting rod located outside the second conduit. A slide for guiding the connecting rod is provided inside the second insertion tube, and a groove that mates with the connecting rod is provided at the end of the slide.

[0009] By adopting the above technical solution, the gas supply pipe is connected to the gas supply end through the first connector. Since the gas supply end is often close to the human body, the first conduit and the first insertion tube are connected by threads to ensure the stability of the connection. The first connecting ring and the protrusion play a role in saving effort when tightening the first conduit. The gas supply pipe is connected to the gas source through the second connector. Since the gas source is often far away from the human body, the connecting rod and the slide are used to ensure quick installation so that the gas source can be activated as soon as possible to supply gas. At the same time, the split design avoids the problem of difficulty in untying the gas supply pipe after it is knotted. It is convenient to store the gas supply end, the conduit and the gas source separately and to facilitate later maintenance.

[0010] Furthermore, the bump is provided with a protrusion for pointing towards the first conduit.

[0011] When underwater or in environments with insufficient underground lighting, the protrusion is used to point to the first conduit for easy installation.

[0012] Furthermore, a first baffle is provided at the bottom of the first cannula, and the first baffle is provided with a filter screen that matches the inner diameter of the first conduit.

[0013] During the installation of the gas supply pipe, ambient air inevitably gets mixed in. The filter can effectively prevent ambient air from entering the gas supply end, and at the same time, it can also filter the gas supply to avoid harm to the human body.

[0014] Furthermore, the connecting rod includes a fixed part and a movable part. The fixed part is fixedly connected to the second conduit, and the fixed part and the movable part are engaged. A cavity for installing a spring is formed between the fixed part and the movable part.

[0015] The connecting rod engages with the groove at the end of the slide in the second insertion tube. When sliding inside the slide, the spring is in a compressed state. When the connecting rod is in the groove, the spring in the connecting rod returns to its original state, and the deformation is reduced, so that the connecting rod is locked in the slide groove. This ensures quick installation and fixes the second insertion tube and the second conduit.

[0016] Preferably, the starting point of the slide is provided with an inclined surface.

[0017] The connecting rod compresses the spring under the action of the inclined plane, thus facilitating entry into the slide.

[0018] Furthermore, the slide includes at least one corner of not less than 90 degrees.

[0019] After the connecting rod enters along the slide and passes the corner, it is locked into the slot to ensure that the second conduit will not be displaced outward during the insertion of the second tube, which would cause secondary pollution to the gas inside the tube. At the same time, it ensures the sealing and stability after installation.

[0020] Furthermore, the bottom of the slot is provided with a movable plate that abuts against the connecting rod, and the outer surface of the second insertion tube is provided with a button that is connected to the movable plate.

[0021] Once the connecting rod is engaged in the slot, both ends of the connecting rod are pressed against the movable plate by the internal springs. At this time, the button extends outward. To unlock the connecting rod, simply press the button and follow the reverse steps of the second guide tube installation trajectory to remove the second guide tube.

[0022] Furthermore, the second connector is provided with a second baffle.

[0023] Furthermore, the second baffle is disposed at the top of the second conduit, and the second baffle has an outer diameter that matches the inner diameter of the second insertion tube.

[0024] The second baffle seals the second connector and limits the top of the second conduit during insertion, facilitating insertion. It also filters the gas entering the gas supply pipe to prevent harm to the human body.

[0025] Furthermore, a second connecting ring is provided between the second conduit and the air supply pipe.

[0026] It facilitates the rotation of the second conduit during installation and also limits the insertion depth of the second conduit.

[0027] Furthermore, the gas supply pipe is provided with an elastic winding support inside or the pipe body is provided with winding reinforcing ribs.

[0028] In actual use, the gas supply pipe can withstand deformation according to the usage environment, which improves its service life and has object-oriented universality.

[0029] In summary, this application has at least the following beneficial effects:

[0030] 1. The first and second connectors, as quick-release structures, can effectively improve installation efficiency. Since the first connector is close to the human body, the connection between the first insertion tube and the first conduit is achieved through a threaded connection, ensuring the reliability of the connection. The second connector is far from the human body. Therefore, a connecting rod is inserted through the second conduit, and a slide rail that matches the connecting rod is set inside the second insertion tube. The end of the slide rail and the end of the connecting rod are fitted with grooves, which enable a quick and reliable connection between the second conduit and the second insertion tube.

[0031] 2. Both the first and second connecting parts are equipped with a first baffle and a second baffle, respectively, to ensure the sealing of the first and second connecting parts. Both the first and second baffles are equipped with filters to filter the supplied air, preventing harmful gases from entering and harming the human body due to the installation process or other reasons.

[0032] 3. The gas supply pipe is equipped with an elastic winding support or the pipe body is equipped with winding reinforcing ribs, so that the gas supply pipe can withstand deformation according to the actual use environment, which improves the service life and has universal applicability.

[0041] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0042] Example 1

[0043] refer to Figure 1 A gas supply assembly for connecting a gas supply end and a gas source, comprising a gas supply pipe, and a first connector and a second connector respectively disposed at both ends of the gas supply pipe, as shown in the reference. Figures 1-3 The first connector includes a first conduit and a first insertion tube, wherein the first conduit is connected to the air supply tube via a first connecting ring, as shown in the reference. Figure 1 The first conduit has external threads, and the first connecting ring has at least one protrusion with a protrusion pointing in the direction of the first conduit; Reference Figure 2 , 3 The first insertion tube is sealed to the gas supply end and connects the inside and outside of the gas supply end. The first insertion tube is provided with an internal thread that matches the external thread of the first conduit. The bottom of the first insertion tube is also provided with a first baffle, and the first baffle is provided with a filter screen that matches the inner diameter of the first conduit.

[0044] It should be noted that the first connecting ring serves to limit the installation depth of the first catheter, therefore the outer diameter of the first cannula needs to be smaller than the outer diameter of the first connecting ring.

[0045] refer to Figure 1 , 4 ~7, the second connector includes a second catheter and a second cannula, see reference. Figure 1 The second conduit is connected to the gas supply pipe via the second connecting ring, see reference. Figure 4The top of the second conduit is provided with a second baffle, and the second baffle is provided with a filter screen that matches the inner diameter of the second conduit.

[0046] Further reference Figure 5 The second conduit is fitted with a connecting rod, with both ends of the connecting rod located outside the second connecting rod, for reference. Figure 5 The connecting rod includes a fixed part and a movable part connected to the second conduit. The fixed part and the movable part form a cavity for installing the spring. The fixed part and the movable part are connected by a snap-fit ​​structure.

[0047] Combination Figure 1 And refer to Figure 6 , 7 The second insertion tube is connected to the air source. The inner wall of the second insertion tube has a slide that mates with the end of the connecting rod. The slide includes at least one corner of not less than 90 degrees. The end of the slide has a groove for accommodating the connecting rod in its compressed state when not in a sliding state, and for limiting the connecting rod's position. Further reference... Figure 6 , 7 The bottom of the card slot is equipped with a movable plate, which is connected to the button that passes through the second insertion tube.

[0048] The starting point of the slide also has an inclined section for compressing the connecting rod.

[0049] It should be noted that while the second baffle serves to seal the second connector, it also guides the top of the second cannula during insertion. Therefore, the outer diameter of the second baffle is the same as the inner diameter of the second cannula. At the same time, the second connecting ring limits the installation depth of the second cannula, so the outer diameter of the second cannula needs to be smaller than the outer diameter of the second connecting ring.

[0050] The gas supply component in this embodiment will now be described through the installation process:

[0051] refer to Figures 1-4 6, 7, a gas supply assembly for connecting a gas supply end and a gas source, comprising a gas supply pipe and a first connector and a second connector disposed at both ends of the gas supply pipe, see reference. Figures 1-3The first connector includes a first conduit and a first insert. The first conduit is connected to the gas supply pipe via a first connecting ring. The first conduit has an external thread. The first insert is sealed to the gas supply end, such as an oxygen mask, and connects the inside and outside of the gas supply end. The bottom of the first insert has a first baffle for filtering the gas entering the gas supply end. The first insert has an internal thread that mates with the external thread of the first conduit. When installing the first conduit and the first insert, pinch the first connecting ring. When the ambient light is weak, you can feel the direction of the protrusion on the first connecting ring to determine the direction of the first conduit. After the first conduit is aligned and abuts against the first insert, tighten the first conduit by rotating the first connecting ring. At this time, the protrusion on the first connecting ring facilitates the application of force and can effectively improve the installation speed. When the first connecting ring abuts against the first insert, it means that the installation is in place.

[0052] If the first connector needs to be disassembled, first disassemble the second connector, and then perform the above steps in reverse order.

[0053] refer to Figure 1 , 4 6, 7, The second connecting component includes a second conduit and a second insertion tube. The second conduit is connected to the air supply pipe via a second connecting ring. A connecting rod passes through the second conduit, with both ends extending outside the second conduit and having telescopic capability. The connecting rod includes a fixed end and a movable end, with the fixed end fixedly connected to the second conduit. A second baffle is provided at the top of the second conduit, matching the inner diameter of the second insertion tube. A filter screen matching the inner diameter of the second conduit is also provided on the second baffle. A slide for guiding the compressed connecting rod is provided inside the second insertion tube. The slide includes at least one corner greater than 90 degrees. The end of the slide has a slot for accommodating the connecting rod in a compressed state outside the slide. A movable plate is also provided in the slot. The movable plate and the connecting rod passing through the second insertion tube are used to compress the connecting rod located in the slot. The connecting rod is connected by a button. The starting point of the slide is also provided with an inclined section for compressing the connecting rod. When installing the second conduit and the second insertion tube, the air supply pipe is twisted due to the installation of the first connector. Therefore, the air supply pipe needs to be straightened before pinching the second connecting ring. The second connecting ring can be provided with protrusions and bumps to distinguish the direction and save effort during installation. Insert the second conduit into the second insertion tube. At this time, the connecting rod is compressed at the inclined section at the starting point of the slide. However, since the outer diameter of the second baffle matches the inner diameter of the second insertion tube, the second conduit will not shift. When the second conduit is inserted to the corner of the slide, rotate the second conduit along the axis to make the connecting rod lock into the slot. At this time, the connecting rod is no longer compressed and abuts against the movable plate in the slot to support the button protruding to the outer wall of the second insertion tube.

[0054] If disassembly is required, press and hold the button and then perform the above steps in reverse order.

[0055] In summary, the air supply pipe will undergo varying degrees of torsion and deformation during installation and disassembly. Therefore, the air supply pipe needs to be made of elastic material and have a flexible support inside, or a flexible hose with flexible reinforcing ribs. Considering the overall cost, service life and manufacturing process, corrugated hoses offer the best cost performance.
