Technical Field
[0001] The present application relates to the technical field of air-conditioning pipes, and in particular to a high-performance vehicle air-conditioning pipe that is easy to bend. Background Art
[0002] Air conditioning pipes were originally designed based on simple metal conduits. However, with advancements in materials science and improved manufacturing processes, modern pipes are now made from corrosion-resistant, high-strength, and thermally conductive alloys such as copper, aluminum, and their alloys. These materials not only enhance the pipe's durability but also its heat exchange efficiency. As people's expectations for quality of life rise, air conditioning systems have become an indispensable feature in modern buildings and transportation. This market demand has driven continuous advancements in pipe production technology and rapid growth in output. To meet the needs of diverse applications, pipe specifications, shapes, and connection methods are also diversifying.
[0003] Traditional air-conditioning pipes are often prone to damage such as folds and cracks at bends due to direct force. This not only affects the cooling efficiency of the air-conditioning system, but may also cause refrigerant leakage, increase maintenance costs and safety hazards. Therefore, this patent needs to be upgraded and modified based on the existing technology. Utility Model Content
[0004] In response to the shortcomings of the existing technology, the present application provides a high-performance automotive air-conditioning pipe that is easy to bend, overcoming the shortcomings of the existing technology. It aims to solve the problem that traditional air-conditioning pipes are often prone to damage such as folds and cracks at the bends due to direct force, which not only affects the cooling efficiency of the air-conditioning system, but may also cause refrigerant leakage, increase maintenance costs and safety hazards.
[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a high-performance automotive air-conditioning pipe that is easy to bend, comprising a bending spring and an air-conditioning copper tube, the bending spring being sleeved on the outside of the air-conditioning copper tube, the bending spring being a spiral structure, wherein the coils in the spiral structure of the bending spring are tightly connected without gaps, the front and rear ends of the bending spring are fixedly connected to a tension spring, the end of the tension spring is fixedly connected to a connector, the outer side of the connector is fixedly connected to the inside of a first knob, the first knob is rotatably connected to a second knob at a position close to the bending spring, the first knob is fixedly connected to an external threaded layer at a position close to the bending spring, the second knob is provided with an internal threaded layer on a side away from the bending spring, the external threaded layer and the internal threaded layer are threadedly connected, a spring slide groove is provided on one side of the first knob, and the tension spring is slidably connected to the inside of the spring slide groove.
[0006] By adopting the above technical solution, when in use, the position where the air-conditioning copper tube needs to be bent is selected according to needs, and then the bending spring is slid to the area to be bent, and the first knobs at both ends of the bending spring are rotated so that the first knob drives the internal connector to rotate with the first knob. When the first knob is rotated, the outer thread layer on one side is driven to rotate with the first knob. Since the outer thread layer and the inner thread layer are threadedly connected, when the first knob is rotated, the second knob is driven away from the first knob. At this time, the tension spring is driven to rotate and extend. During the rotation and extension process, the tension spring drives the bending spring to rotate along the thread direction, thereby driving the bending spring The bending spring contracts inward until the bending spring completely fits the air-conditioning copper tube, and then bends it according to on-site requirements. Since the outer side of the air-conditioning copper tube fits, it effectively prevents the air-conditioning copper tube from being collapsed during the bending process. After the bending is completed, the first knob is rotated in the opposite direction so that the second knob and the first knob are close to each other. At this time, the tension spring no longer generates a force along the spiral direction on both ends of the bending spring, and the bending spring will quickly recover and no longer fit tightly against the outer side of the air-conditioning copper tube. At this time, the bending spring can slide freely on the outside of the air-conditioning copper tube, and then slide the air-conditioning copper tube to a new bending position as needed to repeat the operation.

[0008] By adopting the above technical solution, the notch is set between the first knob and the second knob to facilitate the user's rotation operation, improve the safety and convenience of operation, and prevent slipping during the rotation process.
[0009] According to the claim, a high-performance vehicle air-conditioning duct that is easy to bend is characterized in that a fixing bolt is slidably connected inside the first knob, a sliding groove is provided on the outside of the fixing bolt, a toggle block is slidably connected inside the sliding groove, and the toggle block is fixedly connected to the outside of the fixing bolt.
[0010] By adopting the above technical solution, the fixing bolt can be controlled to slide inside the first knob through the toggle block, and the sliding groove can limit the sliding range of the toggle block to limit the sliding of the fixing bolt inside the first knob.
[0011] According to the claim, a high-performance vehicle air-conditioning pipe that is easy to bend is characterized in that a fixing hole is provided inside the second knob, and a plurality of fixing holes are provided inside the second knob in a circumferential arrangement order, and the diameter of the fixing bolt is smaller than the diameter of the fixing hole.
[0012] By adopting the above technical solution, the fixing bolt moves with the toggle block by sliding the toggle block, and when the toggle block slides toward the second knob, the fixing bolt is just inserted into the fixing hole.
[0013] According to the claim, a high-performance vehicle air-conditioning pipe that is easy to bend is characterized in that the length of the fixing bolt is greater than the length of the sliding groove, and the length of the sliding groove is greater than the length of the external thread layer.
[0014] By adopting the above technical solution, during the rotation of the first knob and the second knob, the external thread layer on the first knob will push the second knob to move along the thread direction, thereby increasing the distance between the two. After the bending spring reaches the required tightness, the fixing bolt can be inserted into the fixing hole by sliding the toggle block, thereby fixing the first knob and the second knob to prevent the two knobs from loosening during the bending process.
[0015] According to the claim, a high-performance vehicle air-conditioning pipe that is easy to bend is characterized in that the outer surface of the air-conditioning copper pipe is also coated with a protective coating, and the inner wall of the spring slide groove is coated with a lubricating material.
[0016] By adopting the above technical solutions, the protective coating can enhance its corrosion resistance and wear resistance, further protecting the integrity of the air-conditioning copper tube during bending and use. The lubricating material can reduce the friction of the tension spring during sliding, improve the sliding smoothness, and extend the service life of the spring and slide.
[0017] The high-performance vehicle air-conditioning pipe that is easy to bend according to the claim is characterized in that the bending spring is made of stainless steel or a high-elasticity alloy.
[0018] By adopting the above technical solution, its corrosion resistance and fatigue resistance are improved.
[0019] Beneficial effects of this application:

[0028] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0029] Reference Figure 1-6A high-performance vehicle air-conditioning pipe that is easy to bend includes a bending spring 1 and an air-conditioning copper pipe 2. The bending spring 1 is sleeved on the outside of the air-conditioning copper pipe 2. The bending spring 1 is a spiral structure, wherein the coils in the spiral structure of the bending spring 1 are tightly connected without gaps. The front and rear ends of the bending spring 1 are fixedly connected to a tension spring 5. The end of the tension spring 5 is fixedly connected to a connector 6. The outside of the connector 6 is fixedly connected to the inside of the first knob 3. The first knob 3 is rotatably connected to the second knob 4 near the side of the bending spring 1. The first knob 3 An external thread layer 7 is fixedly connected to one side of the bending spring 1, and an internal thread layer 8 is provided on the side of the second knob 4 away from the bending spring 1. The external thread layer 7 and the internal thread layer 8 are threadedly connected. A spring slide groove 9 is provided on one side of the first knob 3, and the tension spring 5 is slidably connected to the inside of the spring slide groove 9. When in use, the position where the air-conditioning copper tube 2 needs to be bent is selected according to needs, and then the bending spring 1 is slid to the area to be bent, and the first knobs 3 at both ends of the bending spring 1 are rotated so that the first knob 3 drives the internal connector 6 to follow the first When the knob 3 is rotated, the outer thread layer 7 on one side will be driven to rotate along with the first knob 3 when the first knob 3 is rotated. Since the outer thread layer 7 and the inner thread layer 8 are threadedly connected, when the first knob 3 is rotated, the second knob 4 will be driven to move away from the first knob 3. At this time, the tension spring 5 will be driven to rotate and extend. During the rotation and extension process, the tension spring 5 will drive the bending spring 1 to rotate along the thread direction, thereby driving the bending spring 1 to contract inward until the bending spring 1 completely fits the air-conditioning copper tube 2, and then bend it according to on-site requirements. Since the outer side of the air-conditioning copper tube 2 fits, the air-conditioning copper tube 2 is effectively prevented from being collapsed during the bending process. After the bending is completed, the first knob 3 is rotated in the opposite direction so that the second knob 4 and the first knob 3 are close to each other. At this time, the tension spring 5 no longer generates a force along the spiral direction on both ends of the bending spring 1. The bending spring 1 will quickly recover and no longer tightly fit the outer side of the air-conditioning copper tube 2. At this time, the bending spring 1 can slide freely on the outside of the air-conditioning copper tube 2, and then the air-conditioning copper tube 2 is slid to a new bending position as needed to repeat the operation.
[0030] In this embodiment, if Figure 1 - Figure 6 As shown, notches are provided on the outside of the first knob 3 and the second knob 4. There are multiple groups of notches arranged in a circular order on the outside of the first knob 3 and the second knob 4. The notches are provided to facilitate the user's rotation operation when rotating between the first knob 3 and the second knob 4, thereby improving the safety and convenience of the operation and preventing slipping during the rotation process.
[0031] In this embodiment, if Figure 1 - Figure 6As shown, a fixing bolt 10 is slidably connected inside the first knob 3, and a sliding groove 11 is provided on the outside of the fixing bolt 10. A toggle block 12 is slidably connected inside the sliding groove 11. The toggle block 12 is fixedly connected to the outside of the fixing bolt 10. The fixing bolt 10 can be controlled to slide inside the first knob 3 by the toggle block 12. The sliding groove 11 can limit the sliding range of the toggle block 12, thereby limiting the sliding of the fixing bolt 10 inside the first knob 3.
[0032] In this embodiment, if Figure 1 - Figure 6 As shown, a fixing hole 13 is provided inside the second knob 4, and a plurality of fixing holes 13 are arranged in a circular order inside the second knob 4. The diameter of the fixing bolt 10 is smaller than the diameter of the fixing hole 13. By sliding the toggle block 12, the fixing bolt 10 moves with the toggle block 12. When the toggle block 12 slides toward the side of the second knob 4, the fixing bolt 10 is just inserted into the fixing hole 13.
[0033] In this embodiment, if Figure 1 - Figure 6 As shown, the length of the fixing bolt 10 is greater than the length of the sliding groove 11, and the length of the sliding groove 11 is greater than the length of the external thread layer 7. During the rotation of the first knob 3 and the second knob 4, the external thread layer 7 on the first knob 3 will push the second knob 4 to move along the thread direction, thereby increasing the distance between the two. After the bending spring 1 reaches the required tightness, the fixing bolt 10 can be inserted into the fixing hole 13 by sliding the toggle block 12, thereby fixing the first knob 3 and the second knob 4 to prevent the two knobs from loosening during the bending process.
[0034] In this embodiment, if Figure 1 - Figure 6 As shown, the outer surface of the air-conditioning copper tube 2 is also coated with a protective coating to enhance its corrosion resistance and wear resistance, and further protect the integrity of the air-conditioning copper tube 2 during bending and use. The inner wall of the spring slide 9 is coated with lubricating material to reduce the friction of the tension spring 5 during sliding, improve the sliding smoothness, and extend the service life of the spring and slide.
[0035] In this embodiment, if Figure 1 - Figure 6 As shown, the bending spring 1 is made of stainless steel or a high elastic alloy to improve its corrosion resistance and fatigue resistance.
[0036] Working principle: Slide the bending spring 1 along the air-conditioning copper tube 2 to the area to be bent, and rotate the first knob 3. Due to the threaded connection between the outer thread layer 7 and the inner thread layer 8, the rotation of the first knob 3 will drive the second knob 4 away. In this process, the tension spring 5 is stretched, and drives the bending spring 1 to rotate along the thread direction and gradually shrink until it fits tightly against the outside of the air-conditioning copper tube 2. After the spring 1 fits tightly against the air-conditioning copper tube 2, the fixing bolt 10 is inserted into the fixing hole 13 inside the second knob 4 by sliding the toggle block 12. This step fixes the first knob 3 and the second knob 4 together to prevent loosening during the subsequent bending process. After confirming that the bending spring 1 is tightly fitted and the knob is fixed, the air-conditioning copper tube 2 is bent. Due to the supporting effect of the bending spring 1, the copper tube can be effectively prevented from being deflated or deformed during the bending process.
