Description

Technical Field

[0001] This utility model relates to the field of copper pipe assembly technology, specifically to a snap-fit ​​copper pipe assembly for air conditioning refrigeration. Background Technology

[0002] Copper pipes, a key component of air conditioning systems, are primarily installed inside the air conditioner or connect the indoor and outdoor units. Their core function is to act as a medium for refrigerant circulation, ensuring the refrigerant flows smoothly within the outdoor unit and between the indoor and outdoor units. Currently, most air conditioners use Freon as the refrigerant. In actual operation, ensuring the airtightness of every copper pipe connection is crucial.

[0003] A search revealed that patent application CN217683725U discloses an air conditioner copper pipe assembly. While this device ensures the sealing of the flared end of the copper pipe and prevents deformation during use, existing air conditioner copper pipe assemblies have several drawbacks. Firstly, the connection points are constantly exposed to the external environment, making them susceptible to loosening due to accidental contact. Secondly, the current connection relies solely on nuts, which, after prolonged use, are prone to loosening or even falling off due to vibrations generated during air conditioner operation, thus affecting the normal operation and cooling effect of the air conditioner. Therefore, the structural design and connection method of this device urgently need further optimization and improvement. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a snap-fit ​​copper pipe assembly for air conditioning refrigeration, which solves the problems mentioned in the background art.

[0005] The solution of this utility model to the above-mentioned technical problems is as follows:

[0006] A snap-fit ​​copper pipe assembly for air conditioning refrigeration includes a first copper pipe body, and a second copper pipe body is provided on the first copper pipe body.

[0007] A connecting pipe is installed on the side end face of the first copper tube body, a fixing ring is fixedly installed on the first copper tube body, and external threads are opened on both the first copper tube body and the second copper tube body, and a fixing block is threaded on the external thread.

[0008] The first copper tube body and the second copper tube body are fitted with sleeves, and both ends of the sleeves are fitted with fixing brackets, and screws are threaded into the fixing brackets.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, a third sealing ring is installed on the second copper tube body, and a second sealing ring is installed on the first copper tube body.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] The third and second sealing rings effectively create a sealing barrier at the connection between the first and second copper pipe bodies. During the operation of the air conditioning system, the refrigerant is under high pressure and flows at high speed. If the connection is not properly sealed, refrigerant can easily leak, reducing cooling efficiency and potentially causing air conditioning malfunctions. These two sealing rings effectively prevent refrigerant leakage from the connection, ensuring stable system pressure, maintaining good cooling performance, and preventing environmental pollution caused by refrigerant leaks.

[0013] Furthermore, the connecting pipe is embedded and fixed within the second copper pipe body, and the connection between the connecting pipe and the second copper pipe body is sealed by a third sealing ring and a second sealing ring.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] The connecting pipe is embedded in the second copper pipe body and sealed with a sealing ring, greatly enhancing the stability and sealing of the connection. The double sealing effect of the third and second sealing rings further ensures that refrigerant will not leak when flowing through this area, allowing the entire refrigeration cycle system to operate stably and efficiently, extending the service life of the air conditioner.

[0016] Furthermore, the fixing block is limited by a fixing ring, and the connection between the fixing block and the fixing ring is sealed by a first sealing ring.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] The retaining ring limits the position of the retaining block, ensuring that it does not shift or loosen during operation and maintaining the stability of the connection structure between the first and second copper pipe bodies. During air conditioner operation, the copper pipe assembly is subjected to vibration and stress. If the retaining block moves arbitrarily, the copper pipe connection may loosen, affecting the cooling effect. The first sealing ring, at the connection between the retaining block and the retaining ring, seals the connection, preventing external air, moisture, and other impurities from entering the copper pipe. This avoids corrosion caused by impurities, ensuring the cleanliness of the refrigeration system and improving cooling efficiency and equipment reliability.

[0019] Furthermore, connecting plates are fixedly installed at both ends of the sleeve, and bolts are threadedly installed inside the connecting plates, with nuts threadedly installed on the bolts.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] By using bolts and nuts to install the sleeve inside the connecting plate, the sleeve can be firmly fixed to the connection of the copper pipe, thereby protecting the snap-fit ​​copper pipe assembly and preventing the assembly from being directly exposed and loosened due to accidental contact.

[0022] Furthermore, an extrusion block is fitted onto the screw, and a spring washer is sleeved on the screw. The extrusion block extrudes and limits the movement of the fixing ring and the fixing block.

[0023] The beneficial effects of adopting the above-mentioned further solutions are:

[0024] The compression block, under the action of the screw, compresses and limits the fixing ring and the fixing block, further enhancing the stability of the connection between the first and second copper pipe bodies. When the air conditioner vibrates during operation, this compression and limiting structure effectively resists the force generated by the vibration, preventing loosening between the fixing block and the fixing ring. During screw operation, the spring washer prevents the screw from reversing due to its own compression force, avoiding loosening and thus continuously maintaining the compression and limiting effect of the compression block on the fixing ring and the fixing block. This ensures the reliability of the copper pipe assembly connection and improves the operational stability of the entire air conditioning refrigeration system.

[0025] Furthermore, there are four screws in total, and the four screws are arranged in a ring array relative to the sleeve.

[0026] The beneficial effects of adopting the above-mentioned further solutions are:

[0027] Four screws arranged in a ring array apply uniform compressive force to the copper tube assembly inside the sleeve from multiple directions. This prevents damage to the copper tube assembly or loosening of connections due to uneven localized stress. Compared to single or fewer screw fixing methods, the four screws in a ring array provide a stronger and more stable fixing effect, enhancing the stability of the entire copper tube assembly within the sleeve and improving the reliability and durability of the air conditioner.

[0028] This utility model provides a snap-fit ​​copper pipe assembly for air conditioning refrigeration. It has the following beneficial effects:

[0029] By incorporating a third and second sealing ring, an effective sealing barrier is formed at the connection between the first and second copper tube bodies, preventing refrigerant leakage, ensuring stable refrigeration system pressure, maintaining good refrigeration performance, and avoiding environmental pollution caused by refrigerant leakage. Simultaneously, the connecting pipe is embedded within the second copper tube body and, with the double sealing provided by the sealing ring, further ensures that refrigerant will not leak, enabling the refrigeration cycle system to operate stably and efficiently.

[0030] The retaining ring limits the retaining block, preventing displacement or loosening during operation and maintaining the stability of the connection structure between the first and second copper tube bodies. The pressing block, under the action of the screw, presses and limits the retaining ring and retaining block, effectively resisting the forces caused by air conditioner vibrations and preventing loosening between the retaining block and retaining ring.

[0031] The first sealing ring acts as a seal at the connection between the fixing block and the fixing ring, preventing external air, moisture and other impurities from entering the copper tube. This avoids corrosion inside the copper tube due to impurities, ensuring the cleanliness of the refrigeration system and improving refrigeration efficiency and equipment reliability.

[0032] The sleeve is securely fixed to the copper pipe joint by bolts and nuts installed inside the connecting plate, protecting the snap-fit ​​copper pipe assembly and preventing it from being exposed to the outside and loosened by accidental contact.

[0033] Four screws arranged in a ring array can apply uniform compressive force to the copper tube assembly inside the sleeve from multiple directions, avoiding damage to the copper tube assembly or loosening of the connection due to uneven local force, providing a stronger and more stable fixing effect, enhancing the stability of the entire copper tube assembly inside the sleeve, and improving the working reliability and durability of the air conditioner.

[0034] By attaching a spring washer to the screw, the screw can be prevented from reversing through its own compressive force, thus avoiding loosening of the screw. This ensures that the compression block maintains its compressive limiting effect on the fixing ring and the fixing block, guaranteeing the reliability of the copper pipe assembly connection and improving the operational stability of the entire air conditioning refrigeration system.

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0045] Example 1

[0046] A snap-fit ​​copper pipe assembly for air conditioning refrigeration includes a first copper pipe body 1, and a second copper pipe body 2 is provided on the first copper pipe body 1.

[0047] A connecting pipe 101 is installed on the side end face of the first copper pipe body 1. A fixing ring 103 is fixedly installed on the first copper pipe body 1. External threads 201 are opened on both the first copper pipe body 1 and the second copper pipe body 2. A fixing block 202 is threaded on the external threads 201.

[0048] A sleeve 3 is fitted onto the first copper tube body 1 and the second copper tube body 2. A fixing bracket 304 is installed at both ends of the sleeve 3. A screw 303 is installed inside the fixing bracket 304 by means of threads.

[0049] A third sealing ring 203 is installed on the second copper pipe body 2, and a second sealing ring 104 is installed on the first copper pipe body 1. The arrangement of the third sealing ring 203 and the second sealing ring 104 can form an effective sealing barrier at the connection between the first copper pipe body 1 and the second copper pipe body 2. During the operation of the air conditioning refrigeration system, the refrigerant inside is in a state of high pressure and high speed flow. If the connection is not well sealed, the refrigerant is very easy to leak, which will not only reduce the refrigeration efficiency, but may also cause air conditioning malfunction. These two sealing rings can effectively prevent refrigerant from seeping out from the connection, ensure the pressure of the refrigeration system is stable, maintain good refrigeration performance, and at the same time avoid environmental pollution caused by refrigerant leakage.

[0050] The connecting pipe 101 is embedded and fixed inside the second copper pipe body 2. The connection between the connecting pipe 101 and the second copper pipe body 2 is sealed by the third sealing ring 203 and the second sealing ring 104. The embedding of the connecting pipe 101 inside the second copper pipe body 2 and the sealing with the sealing rings greatly enhance the stability and sealing of the connection. The double sealing effect of the third sealing ring 203 and the second sealing ring 104 further ensures that the refrigerant will not leak when flowing through this point, enabling the entire refrigeration cycle system to operate stably and efficiently, and extending the service life of the air conditioner.

[0051] The fixing block 202 is limited by the fixing ring 103, and the connection between the fixing block 202 and the fixing ring 103 is sealed by the first sealing ring 102. The limiting effect of the fixing ring 103 on the fixing block 202 ensures that the fixing block 202 will not shift or loosen during operation, maintaining the stability of the connection structure between the first copper pipe body 1 and the second copper pipe body 2. During air conditioner operation, the copper pipe assembly will be subjected to certain vibrations and stresses. If the fixing block 202 moves arbitrarily, it may cause the copper pipe connection to loosen, affecting the cooling effect. The first sealing ring 102 plays a sealing role at the connection between the fixing block 202 and the fixing ring 103, preventing external air, moisture and other impurities from entering the copper pipe, avoiding corrosion caused by impurities inside the copper pipe, ensuring the cleanliness of the internal refrigeration system, and helping to improve refrigeration efficiency and equipment reliability.

[0052] Both ends of the sleeve 3 are fixedly installed with connecting plates 302. Bolts 301 are installed inside the connecting plates 302 by threads, and nuts are installed on the bolts 301 by threads. The sleeve 3 is securely fixed to the connection of the copper pipe by the cooperation of the bolts 301 and nuts inside the connecting plates 302, thereby protecting the snap-fit ​​copper pipe assembly and preventing the assembly from being directly exposed to the outside and loosened by accidental contact.

[0053] Example 2

[0054] To provide secondary fixation and limit of the components, and to prevent the connection points from loosening and falling off due to vibrations from the air conditioner, for example, such as... Figures 1 to 4 As shown, this utility model also includes:

[0055] A pressing block 305 is fitted onto the screw 303, and a spring washer 306 is sleeved on the screw 303. The pressing block 305 presses and limits the fixing ring 103 and the fixing block 202. Under the action of the screw 303, the pressing block 305 presses and limits the fixing ring 103 and the fixing block 202, which can further enhance the stability of the connection between the first copper pipe body 1 and the second copper pipe body 2. When the air conditioner vibrates during operation, this pressing and limiting structure can effectively resist the force caused by the vibration and prevent the fixing block 202 and the fixing ring 103 from loosening. When the screw 303 is in use, the spring washer 306 can prevent the screw 303 from reversing through its own pressing force, avoiding the screw 303 from loosening, thereby continuously maintaining the pressing and limiting effect of the pressing block 305 on the fixing ring 103 and the fixing block 202, ensuring the reliability of the copper pipe assembly connection, and improving the operational stability of the entire air conditioning refrigeration system.

[0056] There are four screws 303 in total, arranged in a ring array relative to the sleeve 3. This ring array of screws 303 applies uniform compressive force to the copper pipe assembly inside the sleeve 3 from multiple directions, preventing damage to the copper pipe assembly or loosening of connections due to uneven localized stress. Compared to single or fewer screws 303, the four screws arranged in a ring array provide a stronger and more stable fixing effect, enhancing the stability of the entire copper pipe assembly within the sleeve 3 and improving the reliability and durability of the air conditioner.

[0057] Working principle:

The fixing ring 103 ensures that the fixing block 202 will not shift or loosen during operation, and the first sealing ring 102 prevents external air, moisture, and other impurities from entering the copper tube.

[0061] Installation of sleeve 3: Sleeve sleeve 3 onto the first copper pipe body 1 and the second copper pipe body 2. Both ends of sleeve 3 are fixedly installed with connecting plates 302. Sleeve sleeve 3 is installed in the connecting plates 302 by bolts 301 and nuts, which securely fixes sleeve 3 to the connection of copper pipes, protecting the snap-fit ​​copper pipe assembly and preventing the assembly from being directly exposed to the outside and being loosened by accidental contact.

[0062] Installation of screws 303 and compression blocks 305: Screws 303 are threaded into the fixing brackets 304 at both ends of the sleeve 3. Four screws 303 are arranged in a ring array relative to the sleeve 3. Compression blocks 305 are fitted onto the screws 303, and spring washers 306 are sleeved on the screws 303. The compression blocks 305 compress and limit the fixing ring 103 and the fixing block 202. The ring array of screws 303 can apply uniform compressive force to the copper tube assembly inside the sleeve 3 from multiple directions. The spring washers 306 prevent the screws 303 from reversing and loosening, maintaining the compressive limiting effect and enhancing the stability of the connection.
