Abstract
Description
Technical Field
[0001] This utility model relates to the field of copper tube technology, and in particular to an oxygen-free copper microtube structure that enhances pressure resistance. Background Technology
[0002] Oxygen-free copper microtubes are tiny-diameter tubes made of oxygen-free copper. Traditionally, pressurization is achieved by adding a sleeve. However, this structure has significant drawbacks when dealing with copper microtubes of varying diameters: because the sleeve size needs to be precisely matched to the microtube, different sleeve specifications are required for microtubes of different diameters. If the tube diameter difference is large, there will be a wide variety of sleeve specifications, which not only increases the complexity of production and assembly, but also makes it difficult to uniformly control the gap between microtubes of different diameters and the sleeve, which can easily lead to poor sealing or overly tight assembly, thus affecting the pressurization effect and structural stability. Utility Model Content
[0003] The purpose of this invention is to address the problems existing in the background technology by proposing an oxygen-free copper microtube structure that enhances compressive strength.
[0004] The technical solution of this utility model is as follows: an oxygen-free copper microtube structure with enhanced pressure resistance, comprising a copper tube body, and further comprising: a first soft cover tube and a second soft cover tube movably mounted on the copper tube body, wherein a rubber tube is movably inserted at one end of the first soft cover tube and the second soft cover tube, and the inside of the rubber tube is filled with epoxy resin; and a connecting mechanism installed at the ends of the first soft cover tube and the second soft cover tube to tightly cover the copper tube body.
[0005] Optionally, the connecting mechanism includes a pair of second protrusions fixedly connected to both ends of the first flexible cover tube. Each of the second protrusions has a spiral hole. Both ends of the second flexible cover tube are fixedly connected to a first protrusion corresponding to the second protrusion. The first protrusion is provided with a fixing screw that is spirally connected to the spiral hole.
[0006] Optionally, a retainer is fixedly connected to one end of the first and second soft cover tubes, and an injection nozzle inserted into the retainer is fixedly connected to one end of the tubing near the first and second soft cover tubes.
[0007] Optionally, the end of the injection nozzle away from the tubing is provided with an arc-shaped plug.
[0008] Optionally, both the first and second flexible cover tubes have an injection hole at one end near the rubber tube that communicates with the ferrule.
[0009] Optionally, sealing blocks are fixedly connected to both ends of the first and second flexible cover tubes, and tight-fitting holes for the copper tube body to be tightly fitted are provided on both the ends of the first and second flexible cover tubes and the sealing blocks.
[0010] Optionally, both the first and second flexible cover tubes have sealing gaskets on the sides that come into contact with each other.
[0011] In summary, this application includes at least one of the following beneficial technical effects:
[0012] This invention utilizes a combination of a first flexible cover tube, a second flexible cover tube, a rubber tube, and a connecting mechanism. When using an oxygen-free copper microtube to enhance pressure resistance, the copper tube body is inserted into the flexible cover tube and secured with screws and protrusions. Epoxy resin is then injected into the rubber tube through the injection hole to fill the gaps. The flexible cover tube can accommodate microtubes of different diameters, solving the problem of poor compatibility in traditional sleeves and reducing production and assembly complexity. Simultaneously, the epoxy resin, after solidifying and filling the gaps, possesses high strength, supporting the tube wall and effectively improving pressure resistance. Attached Figure Description

[0024] Example
[0025] like Figures 1 to 4As shown, this utility model proposes an oxygen-free copper microtube structure with enhanced compressive strength, comprising a copper tube body 1, on which a first flexible cover tube 2 and a second flexible cover tube 3 are movably mounted. The first flexible cover tube 2 and the second flexible cover tube 3 are made of neoprene rubber. Sealing gaskets 233, made of nitrile rubber, are provided on the contact surfaces of the first flexible cover tube 2 and the second flexible cover tube 3. Injection holes 237, communicating with a retainer 236, are provided at the ends of the first flexible cover tube 2 and the second flexible cover tube 3 near the rubber tube 231. A rubber tube 231 is movably inserted into one end of the first flexible cover tube 2 and the second flexible cover tube 3. The interior of the rubber tube 231 is filled with epoxy resin adhesive, which is an adhesive made by mixing epoxy resin and a curing agent (usually a hardener) in a certain proportion. It is liquid at room temperature and forms a hard solid after curing. The compressive strength of the solidified epoxy resin adhesive is typically between 70-150 MPa. Furthermore, epoxy resin adhesive has a very strong bonding ability with the substrate, and after curing, it forms a strong bond with a variety of materials, thus improving the overall structure's compressive strength.
[0026] Among them, such as Figures 2 to 4 As shown, the ends of the first flexible cover tube 2 and the second flexible cover tube 3 are equipped with a connecting mechanism that tightly fits the first flexible cover tube 2 and the second flexible cover tube 3 around the copper tube body 1. The connecting mechanism includes a pair of second protrusions 239 fixedly connected to both ends of the first flexible cover tube 2. Each of the second protrusions 239 has a spiral hole 240. Both ends of the second flexible cover tube 3 are fixedly connected to a first protrusion 234 corresponding to the second protrusions 239. The first protrusion 234 is provided with a fixing screw 235 that is spirally connected to the spiral hole 240. The fixing screw 235 passes through the first protrusion 234 and is spirally connected to the spiral hole 240 on the second protrusion 239, thus fixing the first flexible cover tube 2 and the second flexible cover tube 3 together and ensuring the stability of the wrapping structure.
[0027] In addition, such as Figures 1 to 4 As shown, a retaining sleeve 236 is fixedly connected to one end of the first flexible cover tube 2 and the second flexible cover tube 3. An injection nozzle 238, which inserts into the retaining sleeve 236, is fixedly connected to the end of the tubing 231 near the first flexible cover tube 2 and the second flexible cover tube 3. The injection nozzle 238 is fixed to the end of the tubing 231 near the flexible cover tube and inserted into the retaining sleeve 236. The end of the nozzle 238 away from the tubing 231 has an arc-shaped plug to facilitate insertion into the retaining sleeve 236 and ensure accurate injection of the epoxy resin. The end of the injection nozzle 238 away from the tubing 231 has an arc-shaped plug.
[0028] It is worth noting that, such as Figures 2 to 4As shown, sealing blocks 232 are fixedly connected to the inside of both ends of the first flexible cover tube 2 and the second flexible cover tube 3. The sealing blocks 232 are fixed inside the inside of both ends of the first flexible cover tube 2 and the second flexible cover tube 3, and the tight locking holes 2311 on them cooperate with the tight locking holes at the tube ends to lock the copper tube body 1. At the same time, because the rubber material is deformable, it can adapt to copper tubes of different thicknesses and enhance the sealing performance. The ends of the first flexible cover tube 2 and the second flexible cover tube 3 and the sealing blocks 232 are all provided with tight locking holes 2311 for the copper tube body 1 to be tightly locked in. The tight locking holes 2311 can adapt to copper tube bodies 1 of different thicknesses. When the tight locking holes 2311 at the ends of the first flexible cover tube 2 and the second flexible cover tube 3 lock the copper tube body 1, because the first flexible cover tube 2, the second flexible cover tube 3 and the sealing blocks 232 are made of rubber, the tight locking holes 2311 deform and tightly lock the copper tube body 1. When the epoxy resin in the tube 231 is filled and the copper tube body 1 is supported in the first soft cover tube 2 and the second soft cover tube 3, a small amount of resin will be squeezed out from the gap between the tight locking hole 2311 and the copper tube body 1.
[0029] In this embodiment, when using an oxygen-free copper microtube structure with enhanced pressure resistance, the copper tube body 1 is placed inside the first flexible cover tube 2 and the second flexible cover tube 3. The first protrusion 234 and the second protrusion 239 are fixed by a fixing screw 235 passing through the spiral hole 240, ensuring that the first flexible cover tube 2 and the second flexible cover tube 3 tightly enclose the copper tube body 1. Simultaneously, the injection nozzle 238 is inserted into the retainer 236, and epoxy resin is injected into the tube 231 through the injection hole 237. The epoxy resin fills the gap between the first flexible cover tube 2 and the second flexible cover tube 3 and the copper tube body 1. The solidified epoxy resin generates uniform pressure due to micro-expansion during curing, and its inherent high strength supports the tube wall of the copper tube body 1, thereby enhancing the pressure resistance of the copper tube body 1. Finally, the sealing block 232 and the sealing gasket 233 further enhance the sealing performance, and the tight locking hole 2311 ensures that the copper tube body 1 is securely inserted. The cooperation of these components enhances the pressure resistance and seals the copper tube body 1, improving its pressure resistance and structural stability.
