[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1 As shown;

[0026] A heat-insulating and leak-proof pipe connecting device for a central air conditioner comprises a pipe body 1.

[0027] In this embodiment: However, traditional devices often rely on complex installation steps and tools, which leads to a long installation process, increased labor costs and time costs. At the same time, if the connection is not in place, air, moisture or other fluids are likely to leak at the connection, affecting the stable operation and energy efficiency of the system. At the same time, the bolted pipe connection may not be strong enough and may be loosened or fallen off due to vibration or external force, posing a safety hazard. In order to solve this technical problem, a fixing component 2 is added on this basis.

[0028] More specifically:

[0029] like Figures 1 to 5 As shown:

[0030] In combination with the above content: the fixing component 2 includes a connecting tube 21, a sliding frame 22 and a limiting ball 23. The outer side of one end of the pipe body 1 is fixedly connected to the connecting tube 21, the outer side of one end of the connecting tube 21 is slidably connected to the sliding frame 22, and the top inner side of the connecting tube 21 is movably connected to a plurality of limiting balls 23. The outer side of the end of the connecting tube 21 is fixedly connected to a spring 24, and the inner side of the end of the connecting tube 21 is slidably connected to a plug 25. A limiting groove 26 is provided on the outer side of the plug 25, and the limiting ball 23 is engaged with the limiting groove 26. The outer side of one end of the plug 25 is fixedly connected to a head 27, and the outer side of the end of the head 27 is fixedly connected to a textured ring 210. The inner side of the connecting tube 21 is fixedly connected to a sealing plate 29, and the upper surface of the sealing plate 29 is fixedly connected to a sealing ring 28. The sealing ring 28 is made of rubber, and the outer side of the sliding frame 22 is fixedly connected to an insulating layer 211

[0031] In this embodiment, when the user uses the device, he first slides the sliding frame 22 downward, and one side of the sliding frame 22 is separated from the limiting ball 23. At the same time, the spring 24 is compressed and stores elastic potential energy. The limiting ball 23 is in the through groove of the connecting tube 21 and will not fall out. At this time, the user can hold the plug 25 and insert it into the interior of the connecting tube 21, so that the limiting groove 26 moves to the position of the limiting ball 23. At this time, the sliding frame 22 is released. Under the action of the spring 24, the sliding frame 22 moves until one side of the sliding frame 22 presses against the limiting ball 23, so that the limiting ball 23 moves to Inside the retaining groove 26, under the action of the spring 24, the retaining ball 23 will firmly clamp the plug 25, thus completing the connection of the pipe body 1. At the same time, the sealing plate 29 and the sealing ring 28 can increase the waterproofness of the pipe body 1. The presence of the textured ring 210 increases the friction between the head 27 and the sealing ring 28, further enhancing the waterproofness of the device. The quick plug-in design achieved by the fixing assembly 2 makes the connection and disconnection process of the pipe body 1 extremely simple and quick, greatly improving construction efficiency and reducing installation costs. This feature is particularly important for devices that require regular maintenance or modification. The built-in sealing ring 28 can effectively prevent air, moisture or other fluids from leaking at the pipe connection, ensuring the stable operation of the central air conditioning system. The improved sealing performance also means reducing energy efficiency losses caused by leakage, improving the overall energy efficiency of the system. The material design of the PPR reinforced composite fiber pipe of the connecting pipe 21 can effectively reduce the heat exchange between the pipe and the external environment when transmitting cold and hot media, reducing energy loss and improving the energy utilization efficiency of the system. This is of great significance for improving the cooling / heating effect of the air conditioning system and reducing operating costs.

[0032] Going further:

[0033] In an optional embodiment, a heat insulation layer 211 is fixedly connected to the outer side of the sliding frame 22 .

[0034] In this embodiment: an insulation layer 211 is added to the outside of the heat-insulating and leak-proof pipe connection device for central air conditioning, and the interior of the insulation layer 211 is designed to be in a vacuum state, which will bring significant multiple benefits. The vacuum insulation layer 211 greatly improves the thermal insulation performance by eliminating the path of internal air convection and heat conduction, and effectively reduces the heat exchange between the pipeline and the external environment during the transmission of cold and hot media, thereby further reducing energy loss and improving the energy efficiency of the air-conditioning system.

[0035] Going further:

[0036] In an optional embodiment, a water-blocking ring 212 is fixedly connected to one side of the plug 25 , and the material of the water-blocking ring 212 is rubber.

[0037] In this embodiment, adding a tight water-blocking ring 212 to the outside of the connection of the heat-insulating and leak-proof pipe connection device for central air conditioning will bring a series of significant benefits. First, the water-blocking ring 212 can further ensure the sealing of the connection, effectively preventing air, moisture or other fluids from leaking at the connection, thereby ensuring the stable operation and high efficiency of the air-conditioning system. Second, good sealing reduces energy loss caused by leakage, improves the energy efficiency ratio of the system, and helps to reduce operating costs.

[0038] Working principle: When the user uses the device, he first slides the sliding frame 22 downward, and one side of the sliding frame 22 is separated from the limiting ball 23. At the same time, the spring 24 is compressed and stores elastic potential energy. The limiting ball 23 is in the through groove opened in the connecting tube 21 and will not fall out. At this time, the user can hold the plug 25 and insert it into the interior of the connecting tube 21 to move the limiting groove 26 to the position of the limiting ball 23. At this time, the sliding frame 22 is released. Under the action of the spring 24, the sliding frame 22 moves until one side of the sliding frame 22 presses against the limiting ball 23, causing the limiting ball 23 to move to the limiting position. Inside the positioning groove 26, under the action of the spring 24, the limiting ball 23 will firmly clamp the plug 25, and the connection of the pipe body 1 is completed. At the same time, the sealing plate 29 and the sealing ring 28 can increase the waterproofness of the pipe body 1, and the presence of the textured ring 210 increases the friction between the head 27 and the sealing ring 28, further increasing the waterproofness of the device. The quick plug-in design realized by the fixing component 2 makes the connection and separation process of the pipe body 1 extremely simple and quick, greatly improving the construction efficiency and reducing the installation cost. This feature is particularly important for devices that require regular maintenance or modification. The built-in sealing ring 28 can effectively prevent air, moisture or other fluids from leaking at the pipe connection, ensuring the stable operation of the central air-conditioning system. The improved sealing also means that the energy efficiency loss caused by leakage can be reduced, and the overall energy efficiency of the system can be improved. The material design of the PPR reinforced composite fiber pipe of the connecting pipe 21 can effectively reduce the heat exchange between the pipe and the external environment when transmitting cold and hot media, reduce energy loss, and improve the energy utilization efficiency of the system. This is of great significance for improving the cooling / heating effect of the air-conditioning system and reducing operating costs. An insulation layer 211 is added to the outside of the heat-insulating and leak-proof pipe connection device for central air conditioning, and the interior of the insulation layer 211 is designed to be in a vacuum state. , will bring significant multiple benefits. The vacuum insulation layer 211 greatly improves the thermal insulation performance by eliminating the internal air convection and heat conduction paths, effectively reducing the heat exchange between the pipeline and the external environment during the transmission of cold and hot media, thereby further reducing energy loss and improving the energy efficiency of the air-conditioning system. Adding a water-blocking ring 212 to the outside of the connection of the thermal insulation and leak-proof pipe connection device for central air conditioning will bring a series of significant benefits. First, the water-blocking ring 212 can further ensure the sealing of the connection, effectively preventing air, moisture or other fluids from leaking at the connection, thereby ensuring the stable operation and high-efficiency performance of the air-conditioning system. Second, good sealing reduces energy loss caused by leakage, improves the energy efficiency ratio of the system, and helps to reduce operating costs.
