Description

Technical Field

[0001] The utility model relates to the field of air-conditioning pipelines, in particular to a connecting pipeline for air-conditioning. Background Art

[0002] The air conditioner's connection to the bellows plays a key role in the drainage of condensate. It not only accelerates the efficient discharge of condensate from the indoor unit, but also reduces the risk of blockage through internal space layout, ensuring unobstructed drainage. Furthermore, the bellows' material selection focuses on durability and corrosion protection, effectively resisting the erosion of condensate and impurities. These features collectively improve the overall reliability of the air conditioning system, reduce failure rates, and minimize maintenance requirements. Existing air conditioner connecting pipes include bellows, which enable the efficient discharge of condensate from the indoor unit. However, during actual use, the bellows may break due to external factors. Traditional repair methods typically involve wrapping with tape, but given the frequent flow of water inside the bellows, this method is often less effective. Not only is it difficult to ensure the repair's integrity, it can also cause the pipe to break again and leak, reducing the bellows' ease of use. Utility Model Content

[0003] Based on this, the purpose of the present invention is to provide a connecting pipe for air conditioning to solve the technical problem that the effect of repairing corrugated pipes by wrapping with tape is not ideal.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a connecting pipe for air conditioning, comprising a corrugated pipe, the corrugated pipe comprising a first broken pipe and a second broken pipe, a connecting sleeve being provided between the first broken pipe and the second broken pipe, two threaded sleeves being threadedly connected at both ends of the connecting sleeve, fastening blocks being provided on both sides of the connecting sleeve, a slope being provided on one side of the fastening block, a clamping block being provided on the outer side of the threaded sleeve, and an inner sleeve being provided on the inner side of the connecting sleeve.

[0005] By adopting the above technical solution, when the corrugated pipe is broken into the first broken pipe and the second broken pipe, the inner sleeve is inserted into the broken pipe and rotated so that the corrugated block and the corrugated groove are precisely engaged, thereby achieving a stable connection inside the pipe. This connection method is simple and easy, and has high firmness, and can quickly restore the use function of the corrugated pipe. At the same time, the tightening effect of the threaded sleeve is used to compress the inclined surface on the fastening block, thereby further strengthening the stability of the connection, which not only enhances the repair effect, but also effectively prevents the pipe from breaking and leaking again after the repair.

[0006] Furthermore, a plurality of corrugated grooves are provided inside the first broken tube and the second broken tube, and are arranged linearly at equal intervals.

[0007] By adopting the above technical solution, multiple corrugated grooves can increase the structural strength of the pipeline. These equidistant and linearly arranged corrugated grooves enable the pipeline to better disperse pressure when subjected to external force, thereby improving the pressure resistance of the pipeline.

[0008] Furthermore, a plurality of corrugated blocks are provided on the inner sleeve and are arranged linearly at equal intervals, and the corrugated blocks and corrugated grooves are engaged and limited.

[0009] By adopting the above technical solution, the equidistant linear arrangement can precisely engage with the corrugated grooves in the corrugated pipe, achieving a stable limiting effect, increasing the contact area of ​​the connection, and thus improving the stability and load-bearing capacity of the connection.

[0010] Furthermore, guide rings are provided on both sides of the inner sleeve and are in an inclined structure for guiding the water flow.

[0011] By adopting the above technical solution, the water flow in the pipeline is ensured to flow smoothly. Its inclined surface structure can reduce the water flow resistance and prevent the water flow from generating turbulence or eddy currents at the connection, thereby improving the water flow transmission efficiency.

[0012] Furthermore, a plurality of the fastening blocks are provided and are arranged in an equidistant annular pattern along the central axis of the connecting sleeve.

[0013] By adopting the above technical solution, a more uniform and stable tightening force can be provided. When the threaded sleeve is tightened, each tightening block can simultaneously and evenly press the broken pipe parts of the inner sleeve and the corrugated pipe, thereby ensuring the tightness and stability of the connection.

[0014] Furthermore, connecting rings are provided on both sides of the corrugated pipe, and water outlets are provided on the surfaces of the connecting rings.

[0015] By adopting the above technical solution, the connecting ring provides a convenient connection method, allowing the corrugated pipe to be easily connected to other pipes or equipment. The connecting ring also enhances the structural strength of the corrugated pipe and improves the pressure bearing capacity of the pipe.

[0016] Furthermore, the fastening block, threaded sleeve, connecting sleeve and inner sleeve are all made of plastic.

[0017] By adopting the above technical solutions, the plastic material has the characteristics of being light and durable. Compared with traditional materials such as metal, the plastic material is lighter, easier to carry and install, and reduces the construction difficulty and cost.

[0018] In summary, the present invention has the following beneficial effects:

[0019] 1. The utility model uses the connecting sleeve and the inner sleeve. When the corrugated pipe is broken into the first broken pipe and the second broken pipe, it can be quickly repaired. First, the inner sleeve is inserted into the first broken pipe and the second broken pipe respectively and rotated so that the corrugated block on the inner sleeve engages with the corrugated groove in the broken pipe to form a stable connection. At the same time, by tightening the threaded sleeve, it presses the inclined surface on the fastening block, thereby further enhancing the stability of the connection. This method avoids the traditional repair method of wrapping with adhesive tape, not only ensuring the firmness of the repair, but also effectively reducing the risk of pipe rupture and leakage again, thereby improving the convenience and applicability of the use of the corrugated pipe.

[0020] 2. The utility model can effectively guide the direction of water flow by setting a guide ring, ensure that the water flows smoothly in the corrugated pipe, reduce turbulence and eddy currents, and thus improve the transmission efficiency of the water flow. At the same time, the inclined structure of the guide ring can also reduce the impact of the water flow on the inner wall of the pipe, reduce the water flow resistance, further protect the corrugated pipe, and extend its service life.

[0029] The following describes an embodiment of the present invention based on its overall structure.

[0030] Example 1:

[0031] A connecting pipe for air conditioning, such as Figures 1-4 As shown, the bellows 1 includes a first broken tube 101 and a second broken tube 102. A connecting sleeve 6 is provided between the first broken tube 101 and the second broken tube 102. Two threaded sleeves 5 are threadedly connected to the two ends of the connecting sleeve 6. A fastening block 4 is provided on both sides of the connecting sleeve 6. A slope 7 is provided on one side of the fastening block 4. A pressing block 8 is provided on the outside of the threaded sleeve 5. An inner sleeve 12 is provided on the inside of the connecting sleeve 6. When the bellows 1 is broken into the first broken tube 101 and the second broken tube 102, the inner sleeve 12 is inserted into the broken tube and rotated so that the corrugated block 9 and the corrugated groove 1 are connected. 0 precise engagement achieves a stable connection inside the pipe. This connection method is simple and easy, and has high firmness, and can quickly restore the use function of the corrugated pipe 1. At the same time, the tightening effect of the threaded sleeve 5 is used to compress the inclined surface 7 on the fastening block 4, thereby further strengthening the stability of the connection, which not only enhances the repair effect, but also effectively prevents the pipe from breaking and leaking again after the repair, improves the use safety and durability of the corrugated pipe 1, brings users a more efficient, stable and safe corrugated pipe repair experience, and improves the use value and satisfaction of the corrugated pipe 1.

[0032] See Figure 1 、 Figure 2 、 Figure 4The first broken pipe 101 and the second broken pipe 102 are provided with a plurality of corrugated grooves 10, which are arranged in an equidistant linear manner. The plurality of corrugated grooves 10 can increase the structural strength of the pipeline. These equidistant linearly arranged corrugated grooves 10 enable the pipeline to better disperse the pressure when subjected to external force, thereby improving the pressure resistance of the pipeline. At the same time, the corrugated grooves 10 also help to improve the stability of the pipeline connection. When the inner sleeve 12 is inserted into the broken pipe and engaged with the corrugated groove 10 through the corrugated block 9, this structure can provide additional friction to prevent the inner sleeve 12 from sliding or shifting inside the pipeline, thereby ensuring the stability and reliability of the connection. Therefore, the provision of the corrugated grooves 10 has a significant beneficial effect on improving the overall performance of the pipeline and the connection effect.

[0033] See Figure 1 、 Figure 2 、 Figure 4 , a plurality of corrugated blocks 9 are provided on the inner sleeve 12, and are arranged in an equidistant linear arrangement. The corrugated blocks 9 and the corrugated grooves 10 are engaged and limited. The equidistant linear arrangement can accurately engage with the corrugated grooves 10 in the corrugated pipe 1, achieving a stable limiting effect, increasing the contact area of ​​the connection, thereby improving the stability and bearing capacity of the connection. At the same time, the engaging and limiting method of the corrugated blocks 9 and the corrugated grooves 10 can effectively prevent the inner sleeve 12 from moving or rotating inside the corrugated pipe 1, ensuring the reliability and sealing of the connection. This limiting method is not only simple and easy, but also effective, and provides a strong guarantee for the rapid repair and stable use of the corrugated pipe.

[0034] Example 2:

[0035] See Figure 1 、 Figure 2 、 Figure 4 A guide ring 11 is provided on both sides of the inner sleeve 12, and has an inclined structure for guiding the water flow to ensure that the water flows smoothly in the pipe. Its inclined structure can reduce the water flow resistance and prevent the water flow from generating turbulence or eddy currents at the connection, thereby improving the water flow transmission efficiency. At the same time, the guide ring 11 can also reduce the accumulation of dirt and impurities at the connection, reducing the risk of pipe blockage and keeping the pipe clean and unobstructed, which not only improves the practicality of the corrugated pipe 1, but also extends the service life of the pipe, bringing users a more convenient and reliable use experience.

[0036] See Figure 1 、 Figure 3There are multiple fastening blocks 4, and they are arranged in an equidistant annular pattern along the central axis of the connecting sleeve 6, which can provide a more uniform and stable fastening force. When the threaded sleeve 5 is tightened, each fastening block 4 can simultaneously and evenly compress the inner sleeve 12 and the broken pipe part of the corrugated pipe 1, thereby ensuring the tightness and stability of the connection. At the same time, the equidistant annular arrangement of multiple fastening blocks 4 also helps to prevent stress concentration at the connection, reducing the risk of connection failure due to excessive local pressure. This layout enhances the integrity and durability of the connection structure, and provides a strong guarantee for the long-term stable operation of the corrugated pipe 1.

[0037] See Figure 1 、 Figure 2 , connecting rings 2 are provided on both sides of the corrugated pipe 1, and a water outlet 3 is opened on the surface of the connecting ring 2. The connecting ring 2 provides a convenient connection method, so that the corrugated pipe 1 can be easily connected to other pipes or equipment. The connecting ring 2 also enhances the structural strength of the corrugated pipe 1 and improves the pressure bearing capacity of the pipe. At the same time, the water outlet 3 on the surface of the connecting ring 2 ensures the smooth discharge of water flow, avoids the accumulation of water flow or the generation of eddy currents inside the pipe, helps to reduce water flow resistance, improve the transmission efficiency of water flow, and also facilitates the user to clean and maintain the inside of the pipe.

[0038] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The materials of the fastening block 4, threaded sleeve 5, connecting sleeve 6 and inner sleeve 12 are all plastic. Plastic material has the characteristics of lightness and durability. Compared with traditional materials such as metal, plastic material is lighter, easier to carry and install, and reduces construction difficulty and cost. At the same time, plastic material also has good corrosion resistance and rust resistance, can be used for a long time in humid or corrosive environments, is not easily damaged, and extends the service life of the corrugated pipe connection structure. In addition, plastic material also has a certain elasticity, which can absorb and buffer external impact force to a certain extent, protect the pipe connection from damage, and improve the stability and safety of the entire corrugated pipe system.

[0039] The embodiment of the present invention is as follows: when the corrugated pipe 1 is broken into two parts, that is, the first broken pipe 101 and the second broken pipe 102 are broken, the inner sleeve 12 is first inserted into the first broken pipe 101 and rotated, so that the corrugated block 9 on the inner sleeve 12 is engaged with the corrugated groove 10 on the first broken pipe 101. At this time, the fastening block 4 is tightly attached to the first broken pipe 101, and then the threaded sleeve 5 is twisted to make the threaded sleeve 5 move on the connecting sleeve 6, so that the pressing block 8 presses against the inclined surface 7 on the fastening block 4, so as to achieve a more stable connection between the fastening block 4, the inner sleeve 12 and the first broken pipe 101. The same operation is performed to connect the second broken pipe 102 to the connecting sleeve 6. At this time, the first broken pipe 101 and the second broken pipe 102 are connected, avoiding the traditional repair method of wrapping with adhesive tape, not only ensuring the firmness of the repair, but also reducing the risk of pipeline rupture and water leakage, thereby improving the convenience and applicability of the corrugated pipe.

[0040] The guide ring 11 at one end of the inner sleeve 12 is an overall inclined structure for guiding the water flow. The guide ring 11 can also prevent dirt and impurities from accumulating in the bellows to a certain extent, thereby maintaining the smooth flow of water.
