Description

Technical Field

[0001] This application relates to the technical field of pipe fittings, and in particular to a copper male fitting, a copper female fitting, and a copper pipe fitting. Background Technology

[0002] Fittings are widely used in various fluid transmission systems, such as water supply, heating, and industrial pipelines. These fittings ensure system stability and safety by connecting different pipelines. With technological advancements, fitting designs have been continuously optimized, improving sealing performance and service life. However, in practical applications, some problems still need to be addressed, especially the increasingly urgent need to reduce costs.

[0003] Especially when large-scale production and low cost are required, existing connectors may result in high costs due to material waste during the manufacturing process. Utility Model Content

[0004] In order to reduce material waste and lower costs, this application provides a copper male connector, a copper female connector, and a copper pipe connector.

[0005] Firstly, this application provides a copper-plated male connector, which adopts the following technical solution:

[0006] A copper male connector includes an insert sleeve and a connecting sleeve.

[0007] The insert cylinder is used to be embedded inside the pipe opening, and the insert cylinder is formed by rolling or spinning the pipe material.

[0008] The connecting cylinder is connected to the embedded cylinder, and the connecting cylinder is used to connect to the female connector. The connecting cylinder is formed by rolling or spinning of the tubing.

[0009] By adopting the above technical solutions, both the insert and connecting cylinders are formed by roll forming or spin forming, reducing or even eliminating cutting, thereby reducing material waste and lowering costs. Furthermore, roll forming or spin forming can improve strength and durability.

[0010] Preferably, the insert cylinder and the connecting cylinder are integrally formed.

[0011] By adopting the above technical solution, the integral molding of the insert and connecting cylinder can improve the overall strength and stability of the joint, reduce errors during assembly, and ensure the reliability of the connection. At the same time, the integrated design can simplify the production process and reduce manufacturing costs.

[0012] Preferably, it also includes an abutment ring.

[0013] The abutment ring is connected to the inner circumferential surface of one end of the connecting cylinder, and the abutment ring is used to fit the female connector.

[0014] By adopting the above technical solution, the sealing performance between the copper male and female connectors is improved, preventing liquid or gas leakage.

[0015] Preferably, the abutment ring is conical, with the smaller end of the abutment ring extending out of the connecting cylinder.

[0016] By adopting the above technical solution, the conical ring design of the abutment ring effectively increases the contact area and sealing performance with the female connector, ensuring a tighter and more reliable connection. Simultaneously, the design of the small end of the abutment ring extending out of the connecting cylinder better guides the docking process, reduces positional deviations during installation, and further enhances the stability and reliability of the connection.

[0017] Secondly, this application provides a copper female connector, which adopts the following technical solution:

[0018] A copper female connector includes an insertion sleeve and a connecting sleeve.

[0019] The insertion cylinder is used to insert into the pipe opening, and the insertion cylinder is formed by rolling or spinning the pipe material.

[0020] The connecting sleeve is rotatably connected to the insertion cylinder, and the connecting sleeve is used to connect to the male connector.

[0021] By adopting the above technical solutions, the insertion cylinder is formed by rolling or spinning the tubing, which improves the strength and durability of the insertion cylinder. At the same time, rolling or spinning reduces or even eliminates cutting, thereby reducing material waste and lowering costs.

[0022] Preferably, the outer peripheral surface of the connecting sleeve is roll-formed with anti-slip texture.

[0023] By adopting the above technical solution, the anti-slip texture can increase the friction between the connecting sleeve and the tool, thereby making it easier for operators to hold and rotate the connecting sleeve more firmly, improving the convenience and safety of the installation and disassembly process.

[0024] Preferably, the outer circumferential surface of the insertion tube is provided with an anti-detachment ring, which is used to press against the inner wall of the tube opening.

[0025] By adopting the above technical solution, the anti-detachment ring can effectively press against the inner wall of the pipe opening, preventing the copper female connector from loosening or falling off during use, and improving the stability and reliability of the connection.

[0026] Preferably, the outer periphery of the insertion tube is provided with a fitting ring and a limiting ring.

[0027] The end face of the fitting ring facing away from the limiting ring is used to fit the male connector.

[0028] The fitting ring and the limiting ring are used for the insertion of the connecting sleeve.

[0029] By adopting the above technical solution, the design of the fitting ring makes the connection between the copper male connector and the copper female connector tighter and more stable, effectively preventing leakage problems caused by poor contact. The limiting ring restricts the position of the connecting sleeve, ensuring the stability of the connection structure and preventing loosening or detachment during use. At the same time, the design between the fitting ring and the limiting ring can better accommodate the connecting sleeve, ensuring the sealing and reliability of the entire pipe fitting system.

[0030] Thirdly, this application provides a copper tubing connector, which adopts the following technical solution:

[0031] A copper-clad pipe fitting includes the aforementioned copper male fitting and copper female fitting.

[0032] By adopting the above technical solution, copper tubing fittings can achieve efficient connection and sealing performance while reducing production costs. Specifically:

[0033] 1. Both the copper male and female connectors are made using roll forming or spin forming processes, which ensures the strength and stability of the structure while reducing cutting and material waste.

[0034] 2. The integrated design of the embedded sleeve and connecting sleeve further enhances the integrity of the joint, reduces potential problems during assembly, and improves the reliability and service life of the product;

[0035] 3. The abutment ring design allows the female connector to fit more tightly during connection, effectively preventing leakage and improving sealing performance;

[0036] 4. The abutment ring is designed in a conical shape, with the smaller diameter end extending out of the connecting cylinder. This shape helps guide the female connector to be inserted smoothly, while increasing the contact area and further enhancing the sealing effect.

[0037] 5. The connecting sleeve is equipped with anti-slip texture, which makes it easy for the operator to rotate and install, reduces slippage, and improves the ease of installation;

[0038] 7. The anti-detachment ring design effectively prevents the insertion tube from falling off during use, ensuring the safety and firmness of the connection;

[0039] 8. The combination of the fitting ring and the limiting ring not only provides a better fit, but also restricts the position of the connecting sleeve, ensuring the accuracy and stability of the connection.

[0040] In summary, this application includes at least one of the following beneficial technical effects:

[0041] 1. Both the insert and connecting tubes are formed by tubular roll forming or spin forming, which reduces material waste and lowers production costs;

[0042] 2. The integrated molding design of the connecting cylinder and the embedded cylinder simplifies the production process, improves production efficiency, and further reduces manufacturing costs;

[0043] 3. The design of the abutment ring increases the stability of the connection. In particular, the small end of the conical ring abutment ring extends out of the connecting cylinder, which effectively prevents loosening caused by vibration and improves the safety and reliability of the overall structure.

[0044] 4. The anti-slip texture design enhances the friction of the connecting sleeve, preventing rotation during use and improving the stability of the connection;

[0045] 5. The anti-detachment ring design effectively presses against the inner wall of the pipe opening, preventing the insertion cylinder from falling out of the pipe opening and ensuring the reliability of the connection and sealing performance;

[0046] 6. The design of the fitting ring and the limiting ring makes the connection tighter. The fitting ring can better fit the male connector, while the limiting ring restricts the position of the connecting sleeve, ensuring the stability and durability of the connection.

Detailed Implementation

[0051] The present application will be further described in detail below with reference to the accompanying drawings.

[0052] Reference Figure 1 This application discloses a copper male connector, including an embedded cylinder 11 and a connecting cylinder 12.

[0053] The insert cylinder 11 is used to be embedded into the pipe opening. The insert cylinder 11 is formed by rolling or spinning the pipe material. Specifically, the insert cylinder 11 consists of two parts: a first section 111 and a second section 112. The first section 111 is cylindrical with a diameter slightly larger than the inner diameter of the pipe, allowing it to be inserted into the pipe opening with an interference fit. The second section 112 is conical with a gradually decreasing diameter, facilitating insertion into the pipe opening.

[0054] For example, the first section 111 of the insert cylinder 11 can be a smooth surface or have tiny spiral patterns to increase friction with the inner wall of the pipe and prevent loosening. In addition, the second section 112 of the insert cylinder 11 can be a smooth cone or a trapezoid with chamfers to accommodate different types of pipe interfaces.

[0055] The connecting cylinder 12 is coaxially fixedly connected to one end of the embedded cylinder 11. The outer circumferential surface of the connecting cylinder 12 is provided with external threads for connection to the female connector. The connecting cylinder 12 is formed by rolling or spinning of tubing.

[0056] The copper male connector also includes an abutment ring 13.

[0057] The abutment ring 13 is conical in shape. The larger diameter end of the abutment ring 13 is coaxially fixed to the inner circumferential surface of one end of the connecting cylinder 12, and the smaller diameter end of the abutment ring 13 extends out of the connecting cylinder 12. The abutment ring 13 is used to fit against the female connector for sealing.

[0058] In one embodiment: the embedded cylinder 11, the connecting cylinder 12 and the abutment ring 13 are integrally formed, and the tube is a copper tube, so that the copper male connector is formed by rolling the copper tube.

[0059] The implementation principle of the copper male connector in this application embodiment is as follows: The entire copper male connector is designed using a roll forming process, which greatly reduces material waste and lowers production costs. The reasonable design of the embedded cylinder 11 and the connecting cylinder 12 allows the connector to be more securely embedded in the pipeline, while ensuring the reliability and sealing of the connection. In particular, the design of the abutment ring 13 effectively increases the contact area between the connector and the female connector, improving the sealing performance.

[0060] Reference Figure 2 This application also discloses a copper female connector, including an insertion cylinder 21 and a connecting sleeve 22.

[0061] The insertion cylinder 21 is used to insert into the pipe opening. The insertion cylinder 21 is formed by rolling or spinning the pipe material.

[0062] In this embodiment: the tube is a copper tube, and the insertion cylinder 21 is formed by rolling copper tube.

[0063] The insertion tube 21 comprises two parts: a front end 211 and a rear end 212. The front end 211 is cylindrical with a diameter slightly larger than the inner diameter of the pipe, allowing it to be inserted into the pipe opening via an interference fit. If necessary, an anti-loosening ring 213 is provided on the outer periphery of the front end 211 to further prevent loosening by pressing against the inner wall of the pipe opening. The rear end 212 is used for connection to the connecting sleeve 22.

[0064] The connecting sleeve 22 is rotatably connected to the insertion cylinder 21, and the connecting sleeve 22 is used to connect to the male connector.

[0065] The connecting sleeve 22 includes a sleeve 221 and a retaining ring 222. The sleeve 221 is fitted over the tail end 212, and the retaining ring 222 is connected to the inner circumferential surface of one end of the sleeve 221.

[0066] The tail end 212 is provided with a fitting ring 214 and a limiting ring 215 on its outer periphery. The outer diameter of the fitting ring 214 is smaller than the inner diameter of the sleeve 221, and the outer diameter of the fitting ring 214 is larger than the inner diameter of the retaining ring 222.

[0067] The outer diameter of the limiting ring 215 is larger than the outer diameter of the retaining ring 222, and the retaining ring 222 is located between the fitting ring 214 and the limiting ring 215.

[0068] The end face of the fitting ring 214 facing away from the limiting ring 215 is used to fit the male connector for sealing.

[0069] The outer circumference of the sleeve 221 is roll-formed with anti-slip texture 223. The inner circumference of the sleeve 221 is provided with internal thread for connecting to a male connector.

[0070] The implementation principle of a copper female connector in this application embodiment is as follows: by using a roll forming process to manufacture the insertion cylinder 21, the amount of material used is significantly reduced, and the production cost is lowered.

[0071] Reference Figure 3 This application also discloses a copper pipe connector, including the aforementioned copper male connector and copper female connector.

[0072] The external thread at the connecting cylinder and the internal thread at the connecting sleeve 22 cooperate with each other to achieve a reliable connection between the copper male connector and the copper female connector.

[0073] Meanwhile, the minimum diameter of the abutment ring 13 (the diameter at the small end of the diameter) is smaller than the outer diameter of the mating ring 214, and the maximum diameter of the abutment ring 13 (the diameter at the large end of the diameter) is larger than the outer diameter of the mating ring 214.

[0074] On the one hand, it facilitates the tight fit of the abutment ring 13 to the fitting ring 214 to achieve a seal; on the other hand, the abutment ring 13 is equivalent to a disc spring, and the elastic deformation of the abutment ring 13 causes the external thread at the connecting cylinder and the internal thread at the connecting sleeve 22 to abut against each other, thereby preventing loosening.

[0075] The implementation principle of the copper pipe joint in this application embodiment is as follows: the entire copper pipe joint is designed using a roll forming process, which reduces material consumption and lowers production costs. The rational design of the copper male and female joints makes the connection of the entire system more stable and reliable, and improves sealing performance.

[0076] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
