Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to a copper pipe for air conditioning connection. Background Technology

[0002] Copper pipes, as a type of non-ferrous metal pipe, are sturdy and corrosion-resistant, making them the first choice for the installation of water supply, heating, and cooling pipes. In air conditioning systems, copper pipes are an important component of the connecting pipes, and their performance directly affects the overall operating efficiency and stability of the air conditioning system.

[0003] Traditional copper pipes, after installation, are usually only covered with insulation sponge on their outer wall, lacking an effective protective structure. They are easily damaged by external physical and chemical corrosion, leading to pipe breakage and leakage, which in turn affects the normal operation of the air conditioning system. In addition, bacteria can easily grow on the inner wall of copper pipes during long-term use, posing a threat to the hygiene and safety of the air conditioning system. Therefore, we have proposed a copper pipe for air conditioning connection to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the lack of effective protection after installation of traditional copper pipes for air conditioning, which are easily damaged and leaked by external factors; and the easy growth of bacteria on the inner wall after long-term use, which threatens the hygiene and safety of the air conditioning system. Therefore, a copper pipe for air conditioning connection is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An air conditioner connection copper pipe includes a copper pipe body, a protective tube sleeved on the outer wall of the copper pipe body, two limiting rings slidably sleeved on the outer wall of the copper pipe body, the two limiting rings being located at both ends of the protective tube, a buffer structure fixedly provided on the inner wall of the protective tube, and a protective layer provided on the copper pipe body.

[0007] In one possible design, the inner walls of the two limiting rings and both ends of the protective tube are provided with matching threads, and the two limiting rings are respectively threaded to both ends of the protective tube.

[0008] In one possible design, a rubber ring is fixedly connected to the inner wall of one side of each of the two limiting rings. The inner wall of the rubber ring is in contact with the outer wall of the copper tube body, and the rubber ring is in contact with one side of the protective tube.

[0009] In one possible design, the buffer structure includes multiple sponge strips, which are fixedly connected to the interior of the protective tube at equal intervals, and the side of each sponge strip closest to the copper tube body is in contact with the outer wall of the copper tube body.

[0010] In one possible design, the inner wall of the protective tube is provided with multiple positioning grooves corresponding to multiple sponge strips, and the multiple sponge strips are respectively fixedly installed in the corresponding positioning grooves.

[0011] In one possible design, the protective layer includes an epoxy coating bonded to the outer wall of the copper tube body, the epoxy coating being made of epoxy resin having good chemical corrosion resistance and a certain degree of flexibility.

[0012] In one possible design, the inner wall of the copper tube body is bonded with an antibacterial coating, which is made of nano-silver ion plating.

[0013] In this application, during the use of the copper tube, the protective tube is sleeved on the outer wall of the copper tube body and fixed by the limiting rings at both ends. The inner wall of the limiting ring and the threads at both ends of the protective tube are engaged with each other. When the limiting ring is tightened, the rubber ring on one side of the inner wall of the limiting ring is deformed by the mutual squeezing of the limiting ring and the protective tube, so that the inner wall of the rubber ring is tightly fitted with the outer wall of the copper tube body, so that the limiting ring is fixed on the copper tube body, and then fixed on the copper tube body through the protective tube.

[0014] When the copper tube is subjected to external vibration or impact, the buffer structure composed of sponge strips on the inner wall of the protective tube plays a role. Multiple sponge strips with equal spacing can disperse external force and absorb vibration energy through their own elastic deformation, reducing the impact of vibration and impact on the copper tube body. The sponge strips are fixed in the positioning grooves on the inner wall of the protective tube to prevent the sponge strips from shifting during use and to ensure stable buffering effect.

[0015] Meanwhile, the epoxy coating on the outer wall of the copper pipe, thanks to the excellent chemical corrosion resistance of epoxy resin, can prevent external corrosive substances from contacting the copper pipe body and avoid corrosion of the outer wall; its flexibility can adapt to the slight deformation of the copper pipe under temperature changes and other conditions, ensuring the integrity of the coating. The antibacterial coating on the inner wall, made of nano-silver ion plating, releases nano-silver ions to destroy the cell structure of bacteria, inhibit bacterial growth, keep the inside of the copper pipe clean, prevent internal corrosion caused by bacteria, and ensure smooth and efficient refrigerant transmission in the air conditioning system.

[0016] Beneficial effects: In this utility model, the copper pipe for air conditioning connection, through the protective pipe sleeved on the outer wall of the copper pipe body, and the limiting rings at both ends, can effectively resist external forces such as collision and compression, prevent the copper pipe body from deforming or breaking, ensure the normal transmission of refrigerant, and improve the reliability of air conditioning system operation.

[0017] In this utility model, the copper pipe for air conditioner connection, through the buffer structure of the inner wall of the protective pipe, can play a good buffering and shock absorption role when the copper pipe is subjected to vibration or external impact, reduce the impact of vibration on the copper pipe, and further extend the service life of the copper pipe.

[0018] In this utility model, the copper pipe for air conditioning connection has an epoxy coating on the outer wall of the copper pipe and a nano-silver ion antibacterial coating on the inner wall, which not only protects the outer wall of the copper pipe from corrosion, but also inhibits the growth of bacteria on the inner wall, ensuring the hygienic and efficient operation of the air conditioning system.

[0019] In this invention, the protective tube outside the copper tube body cooperates with the limiting rings at both ends to resist external forces, prevent the copper tube from deforming and breaking, and ensure the transmission of refrigerant; the buffer structure on the inner wall of the protective tube can buffer and reduce shock, and extend the service life; the epoxy coating on the outer wall of the copper tube body and the nano silver ion plating antibacterial coating on the inner wall respectively prevent the outer wall from being corroded and inhibit the growth of bacteria on the inner wall, ensuring the hygienic and efficient operation of the air conditioning system.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1: Refer to Figure 1-4A copper tube includes a copper tube body 1, with a protective tube 2 fitted on its outer wall and two slidably fitted limiting rings 3. The inner wall of the protective tube 2 is provided with a buffer structure, and the copper tube body 1 is provided with a protective layer. Through the coordinated work of various components, multiple protections are achieved for the copper tube.

[0027] Both inner walls of the two limiting rings 3 and both ends of the protective tube 2 are provided with matching threads. During installation, the limiting rings 3 are screwed onto both ends of the protective tube 2, and the limiting rings 3 and the protective tube 2 are fixed through the threaded connection. A rubber ring 4 is fixedly connected to one side of the inner wall of each limiting ring 3. The inner wall of the rubber ring 4 is in contact with the outer wall of the copper tube body 1, and at the same time, it is in contact with one side of the protective tube 2. When the threads of the limiting rings 3 and the protective tube 2 are tightened, the rubber ring 4 is deformed by the mutual compression between the two, so that its inner wall is tightly attached to the outer wall of the copper tube body 1, thereby firmly fixing the limiting rings 3 and the protective tube 2 to the outer wall of the copper tube body 1, effectively preventing the protective tube 2 from sliding on the copper tube body 1, and playing a good limiting role.

[0028] The buffer structure on the inner wall of the protective tube 2 consists of multiple sponge strips 5. These sponge strips 5 are evenly spaced and fixedly connected to the interior of the protective tube 2, with the side closest to the copper tube body 1 adhering to the outer wall of the copper tube body 1. Specifically, the inner wall of the protective tube 2 has positioning grooves 6 corresponding to the sponge strips 5. During manufacturing, the sponge strips 5 are first processed into shapes that fit the positioning grooves 6, and then fixedly installed in the corresponding positioning grooves 6 by means of bonding or other methods. This structure ensures that the sponge strips 5 are fixed in position within the protective tube 2. When the copper tube is subjected to external impact or vibration, the sponge strips 5 can effectively buffer the impact, reducing the influence of external forces on the copper tube body 1 and protecting the copper tube.

[0029] This application can be used in the field of air conditioning equipment technology, or in other fields applicable to this application.

[0030] Example 2: Reference Figure 4 Based on Embodiment 1, an improvement is made to an air conditioning connection copper pipe, which is applied in the field of air conditioning equipment technology. The protective layer of the copper pipe body 1 includes an epoxy coating 7 and an antibacterial coating 8. The epoxy coating 7 is made of epoxy resin with good chemical corrosion resistance and a certain degree of flexibility, and is attached to the outer wall of the copper pipe body 1 by adhesive bonding. In the actual manufacturing process, the epoxy resin can be evenly applied to the outer wall of the copper pipe body 1 by spraying, brushing, or other processes, and then cured to form the epoxy coating 7, preventing the copper pipe body 1 from being chemically corroded. The antibacterial coating 8 is made of nano-silver ion plating and is attached to the inner wall of the copper pipe body 1 by plating process. Utilizing the antibacterial properties of nano-silver ions, it inhibits the growth of bacteria inside the pipe and ensures a hygienic environment inside the air conditioning connection pipe.

[0031] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
