Detailed Implementation

[0013] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0014] Example 1: This embodiment provides a high-strength refrigeration pipe fitting suitable for air conditioning, including: Corrugated pipe 1, with integrated connecting pipe structure 11 at both ends; Connecting pipe 2 is located at both ends of the corrugated pipe 1 and is connected to the connecting pipe structure 11; Among them, a wave-shaped snap-fit ​​structure 4 is provided on the inner wall of the port of the connecting pipe 2 extending to the corrugated pipe 1, and the snap-fit ​​structure 4 is fitted into the wall of the corrugated pipe 1.

[0015] As can be seen from this embodiment, a high-strength refrigeration pipe fitting suitable for air conditioning includes a corrugated pipe 1, a connecting pipe 2, and a connecting pipe structure 11; The integrated pipe structure 11 at both ends of the corrugated pipe 1 reduces connection nodes and lowers the risk of leakage. The corrugated snap-fit ​​structure 4 at the port of the connecting pipe 2 fits into the wall of the corrugated pipe 1, enhancing the connection's firmness and preventing loosening due to vibration during the refrigeration process. This achieves the effect of improving connection stability and sealing. Furthermore, the tight connection of each component reduces refrigerant leakage, ensuring stable energy efficiency of the refrigeration system. The reasonable structural design reduces pipe resistance, ensuring smooth flow of refrigerant, improving refrigeration effect, and guaranteeing refrigeration efficiency.

[0016] Through the integrated pipe structure 11 and the corrugated snap-fit ​​structure 4, the core effects of stable and sealed connection, high structural strength and guaranteed refrigeration efficiency are achieved. It can adapt to the high-intensity refrigeration requirements of air conditioning and improve the service life and reliability of pipe fittings.

[0017] Example 2: This embodiment provides a high-strength refrigeration pipe fitting suitable for air conditioners. In addition to the technical solutions of the above embodiments, it also has the following technical features.

[0018] Woven mesh fabric 5 is placed on the outside of the corrugated pipe 1.

[0019] As can be seen in this embodiment, the woven mesh 5 is wrapped around the outside of the corrugated pipe 1 to form a reinforcing layer, which improves the overall compressive and tensile strength of the corrugated pipe 1, effectively disperses external impact force, reduces the deformation or damage of the corrugated pipe 1 caused by collision and squeezing, and thus enhances the structural strength and impact resistance of the corrugated pipe 1. Furthermore, the woven mesh 5 can isolate the corrugated pipe 1 from external friction, avoid direct wear of the pipe wall, extend the service life of the pipe fitting, and the woven mesh 5 can protect the surface of the corrugated pipe 1, reduce the corrosive effect of corrosive media on the pipe wall, and improve the wear resistance and service life of the corrugated pipe 1. A woven mesh 5 is installed on the outside of the corrugated pipe 1. Through reinforcement and protection, the structural strength and wear resistance of the corrugated pipe 1 are significantly improved, its service life is effectively extended, and the reliable operation of the pipe fitting is ensured under complex working conditions.

[0020] Example 3: This embodiment provides a high-strength refrigeration pipe fitting suitable for air conditioners. In addition to the technical solutions of the above embodiments, it also has the following technical features.

[0021] The end face of the connecting pipe 2 on the outside of the snap-fit ​​structure 4 is flat, and the woven mesh 5 is tightly pressed against the corrugated pipe 1.

[0022] As can be seen from this embodiment, the flat end face of the connecting pipe 2 tightly presses the woven mesh 5 against the corrugated pipe 1, preventing the mesh from shifting or loosening, ensuring that the protective and reinforcing effect is continuously effective. The flat end face increases the contact area with the mesh, and the tight-fitting structural design helps to improve the uniformity of the pressing force, making the mesh and the corrugated pipe 1 fit more tightly, which helps to strengthen the fixing effect of the woven mesh 5. Furthermore, after the mesh is tightly fixed, the deformation of the corrugated pipe 1 is further restricted, the impact of vibration on the connection is reduced, and the compressed mesh and the corrugated pipe 1 form a stable whole, which enhances the pipe fitting's tensile and impact resistance, improves structural reliability, and enhances the pipe fitting's stability. Furthermore, the flat end face facilitates precise positioning during assembly, improving installation efficiency, while avoiding scratches from sharp end faces on the braided mesh 5 or corrugated pipe 1. The braided mesh 5 fits tightly against the pipe wall, reducing resonance during medium flow, lowering noise, improving the operational stability of the pipe fitting, and optimizing the assembly and user experience of the pipe fitting.

[0023] The design of the flat end face of the connecting pipe 2 tightly pressing the woven mesh 5 against the corrugated pipe 1 not only strengthens the fixing and protection effect of the mesh, but also improves the structural stability of the pipe fitting, while optimizing the ease of assembly, and further ensuring the reliable operation of the pipe fitting under complex working conditions.

[0024] Example 4: This embodiment provides a high-strength refrigeration pipe fitting suitable for air conditioners. In addition to the technical solutions of the above embodiments, it also has the following technical features.

[0025] The two ends of the woven mesh 5 are rolled into a ring structure 51 and pressed tightly against the inner corrugated side of the corrugated pipe 1 wall by the flat surface of the connecting pipe 2 port.

[0026] As can be seen from this embodiment, the annular mesh is tightly pressed against the inner side of the corrugations, further restricting the radial deformation of the corrugated pipe 1, improving the sealing reliability of the connection, preventing media leakage, and the curled structure is tightly fitted with the inner side of the corrugations, so that the mesh, corrugated pipe 1, and connecting pipe 2 form a stable whole, enhancing the pipe fitting's tensile and vibration resistance, and thus enhancing the structural stability of the pipe fitting.

[0027] Example 5: This embodiment provides a high-strength refrigeration pipe fitting suitable for air conditioners. In addition to the technical solutions of the above embodiments, it also has the following technical features.

[0028] The buckle structure 4 is a rubber ring, and a groove 21 is formed on the inner side of the port of the connecting tube 2. The buckle structure 4 is limited and connected in the groove 21.

[0029] As can be seen from this embodiment, the buckle structure 4 is installed inside the port of the connecting pipe 2 in a detachable connection manner, and the inner side of the port of the connecting pipe 2 is provided with a slot 21 to limit and fix the buckle structure 4. Furthermore, the rubber ring material is elastic and can absorb vibration energy, playing a buffering role, reducing vibration and impact during pipe operation, protecting the connection parts, effectively enhancing the buffering effect, and improving structural stability. Furthermore, the 21-type slot design facilitates the quick installation and removal of the rubber ring, improving assembly efficiency. The elastic properties of the rubber ring can adapt to certain dimensional deviations, enhancing the adaptability of the structure and the assembly fault tolerance, thereby improving assembly convenience and structural adaptability.

[0030] The design of the rubber ring buckle being limited within the slot 21 of the connecting pipe 2 enables precise fixing of the buckle structure 4, while also improving the vibration resistance of the pipe fitting, thereby enhancing the connection stability between the connecting pipe 2 and the corrugated pipe 1, optimizing assembly convenience, and further ensuring the reliable operation of the pipe fitting connection.

[0031] Example 6: This embodiment provides a high-strength refrigeration pipe fitting suitable for air conditioners. In addition to the technical solutions of the above embodiments, it also has the following technical features.

[0032] The side of the buckle structure 4 connected to the slot 21 is provided with a limiting edge 41, and the slot 21 is provided with a limiting groove 211 corresponding to the limiting edge 41.

[0033] As can be seen from this embodiment, the limiting edge 41 and the limiting groove 211 are precisely matched to achieve bidirectional limiting of the buckle structure 4, completely preventing its axial or radial displacement in the groove 21. The dual limiting design makes the buckle and the groove 21 more tightly connected, improves the overall vibration and impact resistance of the structure, and strengthens the positioning accuracy and connection strength of the buckle structure 4. The matching design of the limiting edge 41 of the snap-fit ​​structure 4 and the limiting groove 211 of the snap-fit ​​groove 21 enables precise bidirectional limiting of the snap-fit, enhances structural stability, and provides a stronger guarantee for the long-term stable operation of the pipe fitting connection.

[0034] Example 7: This embodiment provides a high-strength refrigeration pipe fitting suitable for air conditioners. In addition to the technical solutions of the above embodiments, it also has the following technical features.

[0035] The irregular sleeve 7 is set in the gap between the connecting pipe 2, the corrugated pipe 1 and the connecting pipe structure 11, and the irregular sleeve 7 fills the gap to form a sealing structure.

[0036] As can be seen from this embodiment, the irregular sleeve 7 is made of a thermally expanding material; During preparation, the irregular sleeve 7 has a regular cylindrical structure, and after assembly, it is heated and expanded, and then it abuts against the mating surfaces of the connecting pipe 2, the bellows 1 and the connecting pipe structure 11. The overall connection strength is high, and the irregular sleeve 7 can be better assembled with the connecting pipe 2, the corrugated pipe 1, and the pipe structure 11, which helps to improve the structural strength.
