Description

Technical Field

[0001] This utility model relates to the technical field of conductive copper tubes, and specifically to a high-temperature resistant conductive copper tube that is easy to connect. Background Technology

[0002] In situations where electromagnetic interference prevention is necessary, such as the casing of electronic equipment or shielded rooms, conductive copper tubing is used to create a shielding layer. Copper tubing effectively blocks the propagation of electromagnetic waves, protecting internal electronic components from external electromagnetic interference. It also prevents unintended leakage of electromagnetic waves generated by the equipment itself, thus avoiding potential adverse interference to the surrounding environment.

[0003] Because existing conductive copper tubes often need to be installed in specific locations or connected to other conductive copper tubes in practical applications, they require both internal sealing and ease of connection. Common fasteners such as screws or bolts cannot meet the installation requirements of axially long cavities. Furthermore, tightening threads inside cavities with long radial dimensions can easily cause localized deformation at the tube ends, affecting the lifespan of the conductive copper tube. In addition, since conductive copper tubes are often cylindrical, the risk of unintended rolling is high. Therefore, limiting devices or binding devices are often required during the stacking and placement of transport boxes to ensure stable positioning of the conductive copper tubes.

[0004] Therefore, there is an urgent need to provide a new solution to address the defects and shortcomings of the existing technologies. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings and deficiencies in the existing technology, this utility model proposes a high-temperature resistant conductive copper tube that is easy to connect.

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

[0007] A high-temperature resistant conductive copper tube that is easy to connect includes a copper tube, characterized in that: connecting sleeves are provided at both ends of the copper tube, the connecting sleeves are installed at both ends of the copper tube by assembly components, a stud is fixedly connected to the side of the connecting sleeve away from the copper tube, and a plug is fixedly connected to the side of the connecting sleeve close to the copper tube, the plug is inserted into the inner cavity of the copper tube from the end and engages with it, and the stud communicates with the wiring hole inside the plug.

[0008] As a further preferred embodiment of this utility model, the outer wall of the plug is interference-fitted with the inner wall of the copper tube.

[0009] As a further preferred embodiment of the present invention, the assembly component includes a limiting groove formed on the inner wall of the end of the copper tube, and a retaining strip is uniformly fixedly connected to the outer wall of the plug, the retaining strip being able to extend into the limiting groove and engage with it.

[0010] As a further preferred embodiment of the present invention, the connecting sleeve has an assembly hole through which the connecting sleeve, the retaining strip and the plug pass in sequence, and the assembly cylinder is inserted into the assembly hole to fix the connecting sleeve and the copper tube.

[0011] As a further preferred embodiment of the present invention, the bottom end of the assembly cylinder is provided with a variable diameter structure, the inner cavity of the assembly cylinder is provided with a pull rod, the bottom end of the pull rod is connected to a plug, and the pull rod drives the plug to move in and out of the inner cavity of the assembly cylinder to realize the change of the outer diameter of the variable diameter structure.

[0012] As a further preferred embodiment of the present invention, the outer wall of the variable diameter structure is provided with long strips arranged in a circular array.

[0013] As a further preferred embodiment of this utility model, the outer diameter of the plug gradually increases from top to bottom.

[0014] As a further preferred embodiment of this utility model, a core block is fixedly connected to the inner cavity of the assembly cylinder, and the inner wall of the core block is threadedly connected to the outer wall of the pull rod.

[0015] As a further preferred embodiment of this utility model, a handle is fixedly connected to the top end of the pull rod.

[0016] As a further preferred embodiment of the present invention, the outer wall of the copper tube is uniformly provided with several pleated protrusions.

[0017] Compared with the prior art, the advantages and positive effects of this utility model include:

[0018] (1) This utility model provides a high-temperature resistant conductive copper tube that is easy to connect. The copper tube is provided with connecting sleeves at both ends.

A stud is fixedly connected to the side of the connecting sleeve away from the copper tube, and a plug is fixedly connected to the side of the connecting sleeve close to the copper tube. The plug is inserted into the inner cavity of the copper tube from the end and engages with it. Thus, the copper tube is sealed inside by the connecting sleeve.

[0030] [First Embodiment]

[0031] like Figure 1-4 The image shows a high-temperature resistant conductive copper tube that is easy to connect, provided in the first embodiment of this utility model. It includes a copper tube 1. Preferably, as shown... Figure 5 As shown, the outer wall of the copper tube 1 in this embodiment is uniformly provided with several pleated protrusions. By uniformly providing several pleated protrusions on the outer wall of the copper tube, the stable positioning of the copper tube during placement and transportation can be effectively improved. There is no need to set additional limiting devices or binding devices, which reduces the safety hazards that may be caused by unexpected rolling.

[0032] like Figure 1 As shown, connecting sleeves 2 are provided at both ends of the copper tube 1. The connecting sleeves 2 are installed at both ends of the copper tube 1 through the assembly component 8. A stud 3 is fixedly connected to the side of the connecting sleeve 2 away from the copper tube 1. The stud 3 enables the fixed installation of the conductive copper tube at a specific position or the fixed connection between it and other conductive copper tubes. A plug 4 is fixedly connected to the side of the connecting sleeve 2 close to the copper tube 1. The plug 4 is inserted into the inner cavity of the copper tube 1 from the end and engages with it. The plug 4 enables the connection between the connecting sleeve 2 and the end of the copper tube 1. The wiring holes inside the stud 3 and the plug 4 are interconnected to meet the internal wiring requirements. In this embodiment, the outer wall of the plug 4 is interference-fitted with the inner wall of the copper tube 1 to further improve the insertion stability of the connecting sleeve 2 in the inner cavity of the end of the copper tube 1.

[0033] Connecting sleeves are installed at both ends of the copper tube. These sleeves are mounted on both ends of the copper tube via assembly components. A stud is fixedly connected to the side of the connecting sleeve furthest from the copper tube, while a plug is fixedly connected to the side of the connecting sleeve closest to the copper tube. The plug is inserted into the inner cavity of the copper tube from the end and engages with it. This achieves internal sealing of the copper tube through the connecting sleeves. Furthermore, the studs fixedly connected to the side of the connecting sleeve furthest from the copper tube allow for fixed installation of the conductive copper tube at a specific location or for fixed connection with other conductive copper tubes. This meets the installation requirements of cavities with long axial dimensions, achieving a sealing effect while facilitating connection and installation. Simultaneously, by using assembly components to replace screws and bolts in existing technologies, it is suitable for installation and fixing inside cavities with long radial dimensions, reducing the possibility of local deformation of the copper tube end caused by tightening screws or bolts, and extending the service life of the conductive copper tube.

[0034] like Figure 2-4 As shown, the assembly component 8 in this embodiment includes a limiting groove 6 opened on the inner wall of the end of the copper tube 1, and a retaining strip 5 is uniformly fixedly connected to the outer wall of the plug 4. The retaining strip 5 can extend into the limiting groove 6 and be inserted into it. The connection of the connecting sleeve 2 in the inner cavity of the end of the copper tube 1 is achieved by inserting the retaining strip 5 into the limiting groove 6.

[0035] like Figure 2-3 As shown, an assembly hole 7 is provided inside the connecting sleeve 2, the retaining strip 5 and the plug 4 passing through it in sequence. The assembly cylinder 81 is inserted into the assembly hole 7 to fix the connecting sleeve 2 and the copper tube 1.

[0036] As a preferred option, such as Figure 2 As shown, the bottom end of the assembly cylinder 81 is provided with a variable diameter structure, and the inner cavity of the assembly cylinder 81 is provided with a pull rod 83. The bottom end of the pull rod 83 is connected to a plug 85. The pull rod 83 drives the plug 85 to enter and exit the inner cavity of the assembly cylinder 81 to realize the change of the outer diameter of the variable diameter structure. Specifically, the change process is as follows: when the pull rod 83 drives the plug 85 from the bottom to the top into the inner cavity of the assembly cylinder 8, the plug 85 opens the variable diameter structure, thereby increasing the outer diameter of the variable diameter structure, thus stably locking the assembly cylinder 81 inside the assembly hole 7. When the pull rod 83 drives the plug 85 from the top to the bottom out of the inner cavity of the assembly cylinder 8, the opening effect of the plug 85 disappears, the outer diameter of the variable diameter structure decreases, thereby making it easier to remove the assembly cylinder 81 from the inner cavity of the assembly hole 7.

[0037] Based on this, in order to achieve the diameter-changing effect of the variable diameter structure, such as Figure 2As shown, the outer diameter of the plug 85 gradually increases from top to bottom; and to achieve the lifting and lowering process of the pull rod 83 within the assembly cylinder 81, a handle 84 is fixedly connected to the top of the pull rod 83. As a further preferred embodiment, to further achieve stable positioning of the assembly cylinder 81 within the assembly hole 7, the outer wall of the variable diameter structure is provided with elongated strips arranged in a circumferential array. The concave-convex structure increases friction to achieve stable positioning of the assembly cylinder 81 within the assembly hole 7. Furthermore, a core block 82 is fixedly connected to the inner cavity of the assembly cylinder 81, and the inner wall of the core block 82 is threadedly connected to the outer wall of the pull rod 83, thereby achieving a uniform lifting and lowering process of the pull rod 83 within the assembly cylinder 81 through the threaded connection.

[0038] The specific working process of this embodiment is as follows:

[0039] Connecting sleeves 2 are provided at both ends of the copper tube 1. The connecting sleeves 2 are installed at both ends of the copper tube 1 through the assembly component 8. A stud 3 is fixedly connected to the side of the connecting sleeve 2 away from the copper tube 1, and a plug 4 is fixedly connected to the side of the connecting sleeve 2 close to the copper tube 1. The plug 4 is inserted into the inner cavity of the copper tube 1 from the end and engages with it. Thus, the connecting sleeve 2 can achieve internal sealing of the copper tube 1. At the same time, the stud 3 fixedly connected to the side of the connecting sleeve 2 away from the copper tube 1 can also achieve fixed installation of the conductive copper tube 1 in a specific position or fixed connection with other conductive copper tubes 1. This meets the installation requirements of the cavity end with a long axial dimension, achieves a sealing effect and facilitates connection and installation. At the same time, by setting the assembly component 8, the screws and bolts in the prior art are replaced, which is suitable for installation and fixing inside the cavity with a long radial dimension. This reduces the possibility of local deformation of the copper tube end caused by tightening the threads of the screws or bolts, and extends the service life of the conductive copper tube.

[0040] When the copper tube 1 is internally wired, the cable is inserted into the rubber plug 4 and then led out from the internal wiring hole of the stud 3; the connecting sleeve 2 is interference-fitted into the inner cavity of the end of the copper tube 1 through the plug 4, thereby ensuring the stability of the fixed installation of the connecting sleeve 2 at the end of the copper tube 1. The plug 4 and the end of the copper tube 1 can be stably connected by the insertion and cooperation of the locking strip 5 and the limiting groove 6. The assembly cylinder 81 is inserted into the assembly hole 7, thereby fixing the connecting sleeve 2 and the copper tube 1.

[0041] By rotating the pull rod 83, the pull rod 83 pulls the plug 85 to rise synchronously under the action of the threaded rotation relative to the core block 82. The plug 85 opens the long strip structure of the circumferential array, thereby stably locking the assembly cylinder 81 inside the assembly hole 7.

[0042] In addition, since copper tube 1 has a high melting point, wiring inside copper tube 1 can have advantages such as high temperature resistance.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may use the disclosed technical content to make changes or modifications to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model, without departing from the scope of the utility model's technical solution, still fall within the protection scope of this utility model's technical solution. In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through specific circumstances.
