Description

Technical Field

[0001] This utility model relates to the technical field of copper pipe connection devices, and in particular to a novel copper pipe connection device. Background Technology

[0002] Copper tubing, as a seamless material, is made from pure copper or copper alloys and precisely formed through pressing or drawing processes. Its material types encompass various alloy systems such as red copper, brass, and bronze. During manufacturing, a one-piece molding process is typically employed to ensure the integrity of the tubing structure and its mechanical strength. It is worth noting that the diameter of copper tubing needs to be customized according to specific application scenarios to meet the usage requirements under different working conditions.

[0003] In the pipeline connection process, if the diameter of the external pipeline is smaller than that of the copper pipe, the interface will not be able to seal effectively, which will lead to connection failure. Conversely, if the diameter of the external pipeline is larger than that of the copper pipe, leakage risk is likely to occur during fluid transmission, which will seriously affect the sealing performance and operational reliability of the system. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art and to propose a new type of copper pipe connection device that can change the diameter of the copper pipe.

[0005] To achieve the above objectives, this utility model proposes a novel copper pipe connection device, comprising a copper pipe body.

[0006] Also includes:

[0007] A support plate, which is fixedly connected to the copper tube body;

[0008] The connecting seat and the connecting tube are slidably connected to the support plate, while the connecting tube is fixedly connected to the connecting seat and passes through both ends of the connecting seat, with one end of the connecting tube extending into the copper tube body.

[0009] A connecting cap is rotatably connected to one end of a connecting tube, and the connecting cap has an internal thread.

[0010] A locking component is disposed on the support plate, and one end of the locking component can be connected to the connecting seat and can lock the connecting seat to the support plate.

[0011] Preferably, the locking component includes a positioning plate and a bolt. The positioning plate is fixedly connected to the connecting seat, and the bolt is rotatably connected to the positioning plate. One end of the bolt passes through the positioning plate. The support plate has a threaded hole, and the threaded hole is threadedly connected to the bolt.

[0012] Preferably, a positioning post is fixedly connected to the bottom surface of the positioning disk, and a positioning groove is provided on the connecting seat for the positioning post to enter.

[0013] Preferably, a sealing ring is fixedly connected to one end of the copper tube body, and the connecting tube is located inside the copper tube body, with one end of the sealing ring able to be in contact with one end of the connecting seat.

[0014] Preferably, a guide tube is fixedly connected to the bottom of the connector, and the connecting tube is located inside the guide tube.

[0015] Preferably, a sealing ring 2 is fixedly connected to the connecting pipe.

[0016] The beneficial effects of this utility model compared with the prior art are as follows:

[0017] 1. By using replaceable connector assemblies, the size of the connecting pipe can be flexibly adjusted according to the specifications of the external pipe, ensuring a tight fit at the interface and eliminating the risk of leakage.

[0018] 2. The locking mechanism enables quick assembly and disassembly through the cooperation of the positioning plate and bolts. The precise fit between the positioning pin and the positioning groove prevents misalignment during installation, significantly improving connection reliability. The double sealing structure (sealing ring one and sealing ring two) forms multiple barriers, effectively preventing fluid leakage.

[0019] 3. The guide tube design optimizes the fluid path, reducing turbulence and pressure loss. The threaded connection of the connector further enhances sealing performance, ensuring long-term stable system operation.

[0028] like Figures 1 to 2 A novel copper pipe connection device includes a copper pipe body 1.

[0029] The copper tube in this utility model also includes: a support plate 2, a connecting seat 3, a connecting tube 4, a connecting cap 5, and a locking component 7;

[0030] The support plate 2 is fixedly connected to the copper pipe body 1, the connecting seat 3 is slidably connected to the support plate 2, and the connecting pipe 4 is fixedly connected to the connecting seat 3. The connecting pipe 4 passes through both ends of the connecting seat 3, and one end of the connecting pipe 4 extends into the copper pipe body 1. The support plate 2 supports the connecting seat 3, while the connecting pipe 4 is mainly used for connecting to external copper pipes. The size of the connecting pipe 4 can be changed according to the size of the external pipe, mainly by using the locking piece 7 set on the support plate 2. One end of the connecting pipe 4 can be connected to the connecting seat 3. By opening the locking piece 7, the connecting seat 3 can be removed and replaced, and the connecting pipe 4 can be replaced to the corresponding size of the external copper pipe. The connecting seat 3 is fixed to the support plate 2 using a locking component 7. The locking component 7 in this utility model includes a positioning plate 8 and a bolt 9. The positioning plate 8 is fixedly connected to the connecting seat 3, and the bolt 9 is rotatably connected to the positioning plate 8. One end of the bolt 9 passes through the positioning plate 8. The support plate 2 has a threaded hole 10, which is threadedly connected to the bolt 9. By unscrewing the bolt 9, the bolt 9 can be separated from the support plate 2, thus allowing the connecting seat 3 to be replaced. The connecting cap 5 is rotatably connected to one end of the connecting pipe 4, and the connecting cap 5 has an internal thread 6. The internal thread 6 is threadedly connected to the external thread of the external copper pipe, thus enabling the connection between the external copper pipe and the connecting pipe 4.

[0031] Specifically, a positioning post 11 is fixedly connected to the bottom surface of the positioning disk 8, and a positioning groove 12 is provided on the support disk 2 for the positioning post 11 to enter. By the positioning post 11 entering the positioning groove 12, the positioning disk 8 and the support disk 2 can be positioned, further improving the positioning effect of the support disk 2 and the positioning disk 8.

[0032] Specifically, a sealing ring 13 is fixedly connected to one end of the copper pipe body 1, and the connecting pipe 4 is located inside the copper pipe body 1. One end of the sealing ring 13 can be attached to one end of the connecting seat 3. By attaching the sealing ring 13 to the connecting seat 3, the sealing effect between the sealing ring 13 and the connecting seat 3 is further improved.

[0033] Specifically, a guide tube 14 is fixedly connected to the bottom of the connector 3, and the connecting tube 4 is located inside the guide tube 14. When the liquid in the external copper tube enters the connecting tube 4, the guide tube 14 can guide the liquid so that the liquid can smoothly enter the copper tube body 1.

[0034] Specifically, a sealing ring is fixedly connected to the connecting pipe 4, and the sealing ring 15 is connected to the external copper pipe, thereby increasing the sealing effect between the external copper pipe and the connecting pipe 4.

[0035] The working principle of this utility model is based on a modular connection and replaceable design concept. The copper pipe body 1 provides a mounting base for the sliding connection seat 3 via a fixedly connected support plate 2. A connecting pipe 4 is fixedly inserted inside the connecting seat 3. One end of the connecting pipe 4 extends into the copper pipe body 1, and the other end is used to connect to an external copper pipe. The outer diameter of the connecting pipe 4 can be replaced according to the size of the external copper pipe to be connected, thus achieving the function of adapting to different specifications of pipes.

[0036] The connection between the connecting seat 3 and the support plate 2 is secured by a locking component 7. The locking component 7 consists of a positioning plate 8 fixed to the connecting seat 3 and a bolt 9 rotatably connected to the positioning plate 8. When the bolt 9 is screwed into the threaded hole 10 on the support plate 2, the connecting seat 3 is pressed tightly against the support plate 2; rotating the bolt 9 in the opposite direction releases the connection, facilitating the replacement of connecting seat 3 assemblies of different specifications. The positioning pin 11 at the bottom of the positioning plate 8 engages with the positioning groove 12 on the support plate 2 to ensure accurate positioning of the connecting seat 3 during installation and prevent misalignment.

[0037] The sealing performance is ensured through a multi-layer sealing structure. The sealing ring 13 at the end of the copper pipe body 1 fits tightly against its end face after the connecting seat 3 is installed, forming the first sealing barrier. The sealing ring 15 installed on the connecting pipe 4 deforms under pressure when connected to the external copper pipe, filling the gap between the connecting pipe 4 and the external copper pipe, forming the second sealing barrier.

[0038] The guide tube 14 extending from the bottom of the connector 3 surrounds the internal flow channel of the connector 4. When external fluid flows in through the connector 4, the guide tube 14 guides and rectifies the fluid, so that the fluid smoothly transitions into the interior of the copper tube body 1, reducing flow resistance and eddy current generation.

[0039] The connecting cap 5 is installed at the end of the connecting pipe 4 by rotation, and its internal thread is used to mate with the external thread of the external copper pipe. When the connecting cap 5 is tightened, a mechanical connection is achieved, and the sealing effect of the sealing ring 15 is enhanced by axial pressure.

[0040] The working principle of this utility model is as follows: The copper pipe body 1 provides a stable mounting base for the sliding connection seat 3 through the fixedly connected support plate 2. A connecting pipe 4 is fixedly installed inside the connecting seat 3. One end of the connecting pipe 4 extends into the copper pipe body 1, and the other end is specifically used to connect to an external copper pipe. The outer diameter of the connecting pipe 4 can be changed according to the size of the external copper pipe to be connected, thereby realizing the function of adapting to different specifications of pipes.

[0041] The connection between the connecting seat 3 and the support plate 2 is secured by a locking component 7. The locking component 7 consists of a positioning plate 8 fixed to the connecting seat 3 and a bolt 9 rotatably connected to the positioning plate 8. When the bolt 9 is screwed into the threaded hole 10 on the support plate 2, the connecting seat 3 is firmly pressed against the support plate 2; rotating the bolt 9 in the opposite direction releases the connection, facilitating the replacement of connecting seats 3 of different specifications. The positioning pin 11 at the bottom of the positioning plate 8 precisely engages with the positioning groove 12 on the support plate 2, ensuring accurate positioning of the connecting seat 3 during installation and effectively preventing misalignment.

[0042] The sealing performance is ensured through a multi-layer sealing structure. The sealing ring 13 at the end of the copper pipe body 1 fits tightly against its end face after the connecting seat 3 is installed, forming the first sealing barrier. The sealing ring 15 installed on the connecting pipe 4 deforms under pressure when connected to the external copper pipe, filling the gap between the connecting pipe 4 and the external copper pipe, forming the second sealing barrier.

[0043] The guide tube 14 extending from the bottom of the connector 3 surrounds the internal flow channel of the connector tube 4. When external fluid flows in through the connector tube 4, the guide tube 14 guides and rectifies the fluid, allowing the fluid to smoothly transition into the interior of the copper tube body 1, significantly reducing flow resistance and eddy current generation.

[0044] The connecting cap 5 is installed at the end of the connecting pipe 4 by rotation. Its internal thread is specially designed to mate with the external thread of the external copper pipe. When the connecting cap 5 is tightened, a reliable mechanical connection is achieved, and the sealing effect of the sealing ring 13 is enhanced through axial pressure, ensuring the integrity and sealing of the entire connection system.
