Description

Technical Field

[0001] This utility model relates to the field of connecting tube packaging technology, and in particular to an integrated packaging structure for connecting tubes. Background Technology

[0002] Air conditioner connecting pipe assemblies are typically packaged in a coiled disc shape and placed on either side of the outdoor unit or stacked together on the back of the outdoor unit. Since the connecting pipe assembly on the back of the unit is in direct contact with the condenser, it may shake or shift during production and transportation. The pipe fitting nuts at the ends of the connecting pipes may strike or scrape against the condenser fins, causing the condenser fins to tilt, resulting in quality problems and after-sales complaints.

[0003] To address this issue, the industry practice is to first seal the connecting pipe assembly with plastic, and then place a separate gasket in a later process to prevent contact between the connecting pipe assembly and the fins. In air conditioners, both the evaporator and condenser use aluminum foil fins threaded onto copper pipes. Their primary function is to increase the heat dissipation area of ​​the radiator, thus increasing the contact surface with air and improving the radiator's heat exchange efficiency, thereby ensuring product performance. Since the condenser is exposed to the outdoors year-round, the reliability and corrosion resistance of the fins are crucial control points.

[0004] Under normal conditions, the cut surface of the aluminum foil fins is uncoated, and the cut surface of the fins will be in long-term contact with the pad during the whole machine packaging. The packaging pad is made of cardboard, which is alkaline. In a "humid" environment, the alkali reacts with the aluminum to produce aluminate crystals, which will corrode the fins and create gaps. This problem of the packaging pad corroding the fins reduces the heat dissipation capacity of the fins.

[0005] Therefore, it is necessary to design a better packaging structure to solve the above problems. Utility Model Content

[0006] This utility model provides an integrated packaging structure for connecting pipes, which solves the problem of corrosion of the fins by the packaging pad.

[0007] This utility model provides an integrated packaging structure for connecting tubes, including:

[0008] A pad, on which a connecting pipe assembly coiled into a disc shape is placed;

[0009] A limiting part is provided on one side of the pad, and the limiting part restricts the pipe joint nut at the end of the connecting pipe assembly;

[0010] At least one baffle is disposed circumferentially along the pad to block the connecting pipe assembly circumferentially; and

[0011] An integrated sealing sleeve is used to enclose the pad and the connecting pipe assembly inside it.

[0012] This utility model uses a limiting part to restrict the pipe joint nut of the connecting pipe assembly, preventing the pipe joint nut from leaking out of the gasket and causing damage to the fins or fin tipping. A baffle blocks the connecting pipe assembly in the circumferential direction, preventing the connecting pipe from leaking out of the gasket and being scratched. Furthermore, the gasket and connecting pipe assembly are encapsulated in an integrated plastic sleeve, covering the gasket and connecting pipe assembly inside the integrated plastic sleeve, so that the gasket no longer comes into contact with the fins, thus eliminating the problem of the gasket corroding the fins.

[0013] In one embodiment, the pad has a fixing part in the middle, and the fixing part is configured to surround the center of the connecting pipe assembly.

[0014] In this embodiment, the connecting tube assembly surrounds the outer periphery of the fixing part, which serves to fix and support the tube. This prevents the connecting tube from being exposed outside the pad due to the loosening of the sealing sleeve caused by the excessive weight of the connecting tube assembly, which could result in the fins cutting the copper tube or the tube joint nut damaging the fins.

[0015] In one embodiment, the fixing part includes a protrusion extending upward from the surface of the pad, the protrusion being used to fix the connecting pipe assembly.

[0016] In this embodiment, the protruding post and the connecting pipe assembly are coiled into a ring, and the connecting pipe assembly is sleeved on the outer periphery of the protruding post, so that the protruding post plays a good role in fixing it.

[0017] In one embodiment, the height of the protrusion is less than or equal to the outer diameter of the connecting pipe assembly.

[0018] In this embodiment, the height of the protrusion is less than or equal to the outer diameter of the connecting pipe assembly, so that the protrusion is approximately flush with the top of the connecting pipe assembly. This ensures a secure fixation while avoiding interference with the sealing process. If the height of the protrusion is too small, it will not be able to secure the drain pipe. If the height of the protrusion is too large, the height difference between the protrusion and the connecting pipe will be too great during sealing, affecting the sealing effect.

[0019] In one embodiment, the pad has a hollowed-out portion in the middle, and the diameter of the hollowed-out portion is less than or equal to the inner diameter of the disc formed by the connecting pipe assembly.

[0020] In this embodiment, for the lightweight connecting pipe assembly, a hollow part is set in the center of the pad, which does not affect its fixing and sealing effect, and can also reduce the pad material and reduce the weight of the pad, thereby reducing production costs.

[0021] In one embodiment, multiple baffles are provided, and the multiple baffles and the limiting portion are evenly distributed in the circumferential direction of the pad.

[0022] In this embodiment, the baffle and the limiting part together block the outer periphery of the connecting tube assembly. This not only completely blocks the outer periphery of the disc of the connecting tube, but also restricts the pipe joint nut at one end of the connecting tube within the limiting part and prevents it from moving freely. This avoids the problem of the pipe joint nut leaking out of the gasket and scratching or puncturing the film of the sealing sleeve, thereby damaging the fins.

[0023] In one embodiment, the height of the baffle is less than or equal to the outer diameter of the connecting pipe assembly.

[0024] In this embodiment, the height of the baffle is designed so that the connecting tube is approximately flush with the top of the baffle. This design effectively blocks the connecting tube from detaching from the pad 1, while also preventing punctures to the integrated sealing film, thus ensuring a good sealing effect. If the baffle is too small, it will not completely block the connecting tube, and the connecting tube may detach from the top of the baffle. If the baffle is too large, it may easily scratch or puncture the sealing film during sealing, affecting the sealing effect.

[0025] In one embodiment, the pad is circular.

[0026] In this embodiment, the circular pad can better fit the periphery of the coiled disc-shaped connecting tube assembly, and the circular pad will not puncture or scratch the sealing film after sealing. This avoids the problem of irregular shapes or sharp corners around the pad puncturing the integrated sealing film, ensuring the effectiveness of sealing. This ensures that the connecting tube assembly will not leak out of the pad or the integrated sealing sleeve, effectively isolating the connecting tube assembly and the fins, thereby preventing the pad from corroding the fins.

[0027] In one embodiment, the limiting portion includes:

[0028] A long baffle, one end of which is connected to the edge of the pad;

[0029] A short baffle is connected to the other end of the long baffle and is set perpendicular to the long baffle;

[0030] A base plate is connected to the bottom of the long baffle, the bottom of the short baffle, and the edge of the pad.

[0031] The long baffle, the short baffle, and the bottom plate are arranged to form the limiting part.

[0032] In this embodiment, the limiting part plays a role in fixing and blocking the pipe joint nut, preventing the pipe joint nut from being exposed outside the gasket, causing the pipe joint nut to come into contact with the fin and damage the fin, resulting in the quality problem of fin collapse.

[0033] In one embodiment, the limiting portion has a guide slope at the edge facing the pad to guide the pipe fitting nut into the limiting portion.

[0034] In this embodiment, when the connecting pipe, which is coiled into a disc shape, is placed on the pad, the pipe connector nut at its end is guided into the limiting part by the guide slope. This can not only prevent the pipe connector nut from damaging the long baffle, but also guide the end of the connecting pipe into the limiting part, making the placement of the connecting pipe smoother.

[0035] Compared with the prior art, the advantages of this utility model are as follows: the connecting pipe assembly is placed on the pad, and the pipe joint nut of the connecting pipe assembly is restricted by the limiting part, which avoids the pipe joint nut from being exposed on the pad and causing the fins to bump or bend. The baffle blocks the connecting pipe assembly in the circumferential direction to prevent the connecting pipe from being exposed on the pad and being scratched. Furthermore, the pad and the connecting pipe assembly are encapsulated in an integrated plastic sleeve, which prevents the pad from contacting the fins and eliminates the problem of the pad corroding the fins. The process of placing the pad is moved forward, reducing transportation steps and improving overall efficiency. Attached Figure Description

[0045] 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.

[0046] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0047] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0048] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0049] Existing air conditioner connecting pipe assemblies involve sealing the connecting pipe and drain pipe together during packaging. In subsequent processes, a pad is placed separately behind the connecting pipe assembly to separate it from the fins and prevent contact that could cause fin tilting. However, the cut surfaces of the fins remain in prolonged contact with the pad, which is made of cardboard and is slightly alkaline. In a humid environment, the alkalinity reacts with the aluminum to produce aluminate crystals, which can corrode the fins, creating gaps. This poses a problem of the packaging pad corroding the fins, reducing their heat dissipation capacity. Furthermore, directly sealing the connecting pipe and drain pipe together makes it easy for the pipe fitting nut at the end of the connecting pipe to scratch or puncture the sealing film, leading to sealing failure. The nut protruding from the sealing film can cause damage to the fins, resulting in fin tilting and other quality issues.

[0050] To address the problems of existing technologies, this utility model provides an integrated packaging structure for connecting pipes, including a pad 1 on which a connecting pipe assembly 2, coiled into a disc shape, is placed; a limiting part 11 is disposed on one side of the pad 1, limiting the pipe joint nut 22 at the end of the connecting pipe assembly 2; at least one baffle 12 is disposed circumferentially along the pad 1 to block the connecting pipe assembly 2 in the circumferential direction; and an integrated sealing sleeve for enclosing the pad 1 and the connecting pipe assembly 2 inside it.

[0051] The connecting pipe assembly 2 is placed on the pad 1, and the pipe joint nut 22 of the connecting pipe assembly 2 is restricted by the limiting part 11 to prevent the pipe joint nut 22 from being exposed from the pad 1 and causing the fins to bump or bend. The baffle 12 blocks the connecting pipe assembly 2 in the circumferential direction to prevent the connecting pipe 21 from being exposed from the pad 1, which would cause the sharp air conditioning fins to cut the connecting pipe 21, resulting in copper pipe scratches, hidden scratches and other after-sales system leakage hazards. The pad 1 and the connecting pipe assembly 2 are integrated into a plastic-sealed package, so that the pad 1 no longer comes into contact with the fins, eliminating the problem of the pad 1 corroding the fins. The process of placing the pad 1 is moved forward, reducing transportation steps and improving overall efficiency.

[0052] Example 1

[0053] like Figures 1 to 3 As shown, the integrated packaging structure for the connecting tube includes a pad 1 on which a connecting tube assembly 2, coiled into a disc shape, is placed; a limiting part 11 is disposed on one side of the pad 1, which restricts the pipe joint nut 22 at the end of the connecting tube assembly 2; at least one baffle 12 is disposed along the circumferential edge of the pad 1 to block the connecting tube assembly 2 in the circumferential direction; and an integrated sealing sleeve for enclosing the pad 1 and the connecting tube assembly 2 inside it.

[0054] A fixing part is provided in the middle of the pad 1. The fixing part is constructed to surround the center of the connecting pipe assembly 2, that is, the connecting pipe assembly 2 surrounds the fixing part. In this embodiment, the fixing part includes a protruding post 13 protruding upward from the surface of the pad 1. The protruding post 13 is used to fix the connecting pipe assembly 2.

[0055] It should be noted that the connecting pipe assembly 2 includes a connecting pipe 21 and a drain pipe 23. The connecting pipe 21 is coiled into a ring and placed on the pad 1 at the outer periphery. The drain pipe 23 is also coiled into a ring and located inside the ring of the connecting pipe 21. The length and diameter of the drain pipe 23 are smaller than those of the connecting pipe 21; therefore, the drain pipe 23 can be located inside the ring of the connecting pipe 21. The connecting pipe 21 also includes an inner copper pipe, an insulation pipe sleeved over the copper pipe, and pipe fitting nuts 22 at both ends of the copper pipe.

[0056] In this embodiment, the drain pipe 23 is coiled into a ring and fitted around the outer periphery of the fixing part. The fixing part plays a role in fixing and supporting, preventing the connecting pipe 21 from being exposed outside the pad plate 1 due to the loosening of the sealing film caused by the excessive weight of the connecting pipe assembly 2, which would cause the fins to cut the copper pipe or the pipe joint nut 22 to damage the fins.

[0057] It should also be noted that the height of the protrusion 13 is less than or equal to the outer diameter of the connecting pipe assembly 2. Preferably, the height of the protrusion 13 is less than or equal to the outer diameter of the connecting pipe 21. In a preferred embodiment, the height of the protrusion 13 is greater than three-quarters of the outer diameter of the connecting pipe 21, and less than or equal to the outer diameter of the connecting pipe 21, so that the connecting pipe 21 and the protrusion 13 are approximately flush. If the height of the protrusion 13 is too small, it cannot effectively fix the drain pipe 23; if the height of the protrusion 13 is too large, the height difference between the protrusion 13 and the connecting pipe 21 will be too large during sealing, affecting the sealing effect.

[0058] It should be noted that multiple baffles 12 are provided, and the multiple baffles 12 and the limiting part 11 are evenly distributed in the circumferential direction of the pad 1. Therefore, the baffles 12 can block the outer periphery of the connecting pipe 21 in the circumferential direction, preventing the connecting pipe 21 from leaking out of the pad 1 and causing the copper tube of the connecting pipe 21 to be cut by the fins.

[0059] It should be noted that the baffle 12 is an arc-shaped piece, and its curvature is consistent with the curvature of the circumference of the pad 1.

[0060] In this embodiment, three baffles 12 are provided, and the three baffles 12 and the limiting part 11 are located at the four equal parts of the circular pad 1. The three baffles 12 and the limiting part 11 can completely block the outer periphery of the disc of the connecting tube 21, and also restrict the pipe joint nut 22 at one end of the connecting tube 21 within the limiting part 11 and prevent it from moving at will. This avoids the problem of the pipe joint nut 22 leaking out of the pad 1 and scratching or puncturing the film of the integrated sealing sleeve, thereby damaging the fins.

[0061] It is also important to note that the height of the baffle 12 is less than or equal to the outer diameter of the connecting tube assembly 2. Preferably, the height of the baffle 12 is greater than three-quarters of the outer diameter of the connecting tube 21, and less than or equal to the outer diameter of the connecting tube 21, so that the top of the connecting tube 21 is approximately flush with the top of the baffle 12. If the height of the baffle 12 is too small, it cannot completely block the connecting tube 21, and the connecting tube 21 may come off from the top of the baffle 12. If the height of the baffle 12 is too large, it is easy for the baffle 12 to scratch or puncture the film of the integrated sealing sleeve during sealing, affecting the sealing effect. Therefore, the height of the baffle 12 is greater than three-quarters of the outer diameter of the connecting tube 21, and less than or equal to the outer diameter of the connecting tube 21. This ensures that the baffle 12 effectively blocks the outer periphery of the connecting tube 21, preventing the connecting tube 21 from coming off the pad 1, and also prevents puncturing the sealing film, thus ensuring the sealing effect.

[0062] In some embodiments, the pad 1 is circular. The circular pad 1 can better fit the periphery of the coiled disc-shaped connecting tube assembly 2. After sealing, the circular pad 1 will not puncture or scratch the sealing film. This avoids the problem of irregular shapes or sharp corners around the pad 1 puncturing the sealing film, ensuring the effectiveness of sealing. This ensures that the connecting tube assembly 2 will not leak out of the pad 1 or the sealing film, effectively isolating the connecting tube assembly 2 and the fins, thereby preventing the problem of the pad 1 corroding the fins.

[0063] In some embodiments, the limiting part 11 includes a long baffle 111, a short baffle 112, and a bottom plate 113. The long baffle 111 is disposed perpendicular to the pad 1, with one end connected to the edge of the pad 1 and the other end connected to the short baffle 112. The short baffle 112 is disposed perpendicular to the long baffle 111 and is also perpendicular to the pad 1. The bottom plate 113 is connected to the bottom of the long baffle 111, the bottom of the short baffle 112, and the edge of the pad 1, and the bottom plate 113 is on the same plane as the pad 1. The long baffle 111, the short baffle 112, and the bottom plate 113 form the limiting part 11. The side of the long baffle 111 is parallel to the end of the disc-shaped connecting pipe 21. Therefore, the pipe joint nut 22 disposed at the end of the connecting pipe 21 enters the limiting part 11 from the edge of the long baffle 111 and is accommodated within the limiting part 11. The limiting part 11 fixes and stops the pipe joint nut 22, preventing the pipe joint nut 22 from being exposed outside the gasket 1, causing the pipe joint nut 22 to come into contact with the fin and damage the fin, resulting in the quality problem of the fin turning over.

[0064] It should be noted that a guide slope 114 is provided on the edge of the limiting part 11 facing the pad 1 to guide the pipe connector nut 22 into the limiting part 11. In this embodiment, the guide slope 114 is provided on the edge of the long baffle 111 away from the short baffle 112. Therefore, when the disc-shaped connecting pipe 21 is placed on the pad 1, the pipe connector nut 22 at its end is guided into the limiting part 11 by the guide slope 114. This can both prevent the pipe connector nut 22 from damaging the long baffle 111 and guide the end of the connecting pipe 21 into the limiting part 11, making the placement of the connecting pipe 21 smoother.

[0065] Example 2

[0066] like Figure 4 and Figure 5 As shown, the integrated packaging structure for the connecting tube includes a pad 1 on which a connecting tube assembly 2, coiled into a disc shape, is placed; a limiting part 11 is disposed on one side of the pad 1, which restricts the pipe joint nut 22 at the end of the connecting tube assembly 2; at least one baffle 12 is disposed along the circumferential edge of the pad 1 to block the connecting tube assembly 2 in the circumferential direction; and an integrated sealing sleeve for enclosing the pad 1 and the connecting tube assembly 2 inside it.

[0067] In this embodiment, the pad 1 has a hollowed-out portion 14 in the middle. By providing the hollowed-out portion 14, the material of the pad 1 can be reduced, thereby reducing material costs and production costs. The hollowed-out portion 14 can be used in the connecting pipe assembly 2, which has a smaller weight, depending on the production situation.

[0068] It should be noted that the connecting pipe assembly 2 includes a connecting pipe 21 and a drain pipe 23. The connecting pipe 21 is coiled into a ring and placed on the pad 1 at the outer periphery. The drain pipe 23 is also coiled into a ring and located inside the ring of the connecting pipe 21. The length and diameter of the drain pipe 23 are smaller than those of the connecting pipe 21; therefore, the drain pipe 23 can be located inside the ring of the connecting pipe 21. The connecting pipe 21 also includes an inner copper pipe, an insulation pipe sleeved over the copper pipe, and pipe fitting nuts 22 at both ends of the copper pipe.

[0069] In this embodiment, the perforated portion 14 is located at the center of the disc formed by the drain pipe 23. The diameter of the perforated portion 14 is less than or equal to the inner diameter of the disc formed by the connecting pipe assembly 2. In other words, the diameter of the perforated portion 14 is less than or equal to the inner diameter of the disc formed by the drain pipe 23. For the relatively lightweight connecting pipe 21 and drain pipe 23, providing the perforated portion 14 at the center of the pad 1 does not affect its fixing and sealing effect, and can also reduce the material of the pad 1, reduce the weight of the pad 1, and thus reduce production costs.

[0070] In this embodiment, three baffles 12 are provided, and the three baffles 12 and the limiting part 11 are located at the four equal parts of the circular pad 1. The three baffles 12 and the limiting part 11 can completely block the outer periphery of the disc of the connecting tube 21, preventing the connecting tube 21 from leaking out of the pad 1 and causing the copper tube of the connecting tube 21 to be cut by the fins. At the same time, it can also restrict the pipe joint nut 22 at one end of the connecting tube 21 within the limiting part 11 and prevent it from moving at will, thus preventing the pipe joint nut 22 from leaking out of the pad 1 and scratching or puncturing the sealing film and damaging the fins.

[0071] It should be noted that the baffle 12 is an arc-shaped piece, and its curvature is consistent with the curvature of the circumference of the pad 1.

[0072] It is also important to note that the height of the baffle 12 is less than or equal to the outer diameter of the connecting pipe assembly 2. Preferably, the height of the baffle 12 is greater than three-quarters of the outer diameter of the connecting pipe 21, and less than or equal to the outer diameter of the connecting pipe 21, so that the top of the connecting pipe 21 is approximately flush with the top of the baffle 12. If the height of the baffle 12 is too small, it cannot completely block the connecting pipe 21, and the connecting pipe 21 may come off from the top of the baffle 12. If the height of the baffle 12 is too large, it is easy to scratch or puncture the sealing film during sealing, affecting the sealing effect. Therefore, the height of the baffle 12 is greater than three-quarters of the outer diameter of the connecting pipe 21, and less than or equal to the outer diameter of the connecting pipe 21. This ensures that the baffle 12 effectively blocks the outer periphery of the connecting pipe 21, preventing the connecting pipe 21 from coming off the pad 1, and also prevents puncturing the sealing film, thus ensuring the sealing effect.

[0073] In some embodiments, the pad 1 is circular. The circular pad 1 can better fit the periphery of the coiled disc-shaped connecting tube assembly 2. After sealing, the circular pad 1 will not puncture or scratch the sealing film. This avoids the problem of irregular shapes or sharp corners around the pad 1 puncturing the sealing film, ensuring the effectiveness of sealing. This ensures that the connecting tube assembly 2 will not leak out of the pad 1 or the sealing film, effectively isolating the connecting tube assembly 2 and the fins, thereby preventing the problem of the pad 1 corroding the fins.

[0074] In some embodiments, the limiting part 11 includes a long baffle 111, a short baffle 112, and a bottom plate 113. The long baffle 111 is disposed perpendicular to the pad 1, with one end connected to the edge of the pad 1 and the other end connected to the short baffle 112. The short baffle 112 is disposed perpendicular to the long baffle 111 and is also perpendicular to the pad 1. The bottom plate 113 is connected to the bottom of the long baffle 111, the bottom of the short baffle 112, and the edge of the pad 1, and the bottom plate 113 is on the same plane as the pad 1. The long baffle 111, the short baffle 112, and the bottom plate 113 form the limiting part 11. The side of the long baffle 111 is parallel to the end of the disc-shaped connecting pipe 21. Therefore, the pipe joint nut 22 disposed at the end of the connecting pipe 21 enters the limiting part 11 from the edge of the long baffle 111 and is accommodated within the limiting part 11. The limiting part 11 fixes and stops the pipe joint nut 22, preventing the pipe joint nut 22 from being exposed outside the gasket 1, causing the pipe joint nut 22 to come into contact with the fin and damage the fin, resulting in the quality problem of the fin turning over.

[0075] It should be noted that a guide slope 114 is provided on the edge of the limiting part 11 facing the pad 1 to guide the pipe connector nut 22 into the limiting part 11. In this embodiment, the guide slope 114 is provided on the edge of the long baffle 111 away from the short baffle 112. Therefore, when the disc-shaped connecting pipe 21 is placed on the pad 1, the pipe connector nut 22 at its end is guided into the limiting part 11 by the guide slope 114. This can both prevent the pipe connector nut 22 from damaging the long baffle 111 and guide the end of the connecting pipe 21 into the limiting part 11, making the placement of the connecting pipe 21 smoother.

[0076] Example 3

[0077] This embodiment is largely the same as embodiment two, except that the number of baffles 12 is different. The same structure will not be described again.

[0078] like Figure 6 As shown, in this embodiment, two baffles 12 are provided. The two baffles 12 and the limiting part 11 are respectively located at the three equal division positions of the circumference of the pad 1. The two baffles 12 and the limiting part 11 can completely block the outer circumference of the disc of the connecting tube 21, preventing the connecting tube 21 from leaking out of the pad 1 and causing the copper tube of the connecting tube 21 to be cut by the fins. At the same time, it can also restrict the pipe joint nut 22 at one end of the connecting tube 21 within the limiting part 11 and prevent it from moving at will, thus preventing the pipe joint nut 22 from leaking out of the pad 1 and scratching or puncturing the sealing film and thus damaging the fins.

[0079] In other embodiments, the baffle 12 can be set as one, four or more as needed. When there are multiple baffles 12, the center of the pad 1 is a protruding post 13 or a hollow part 14, depending on the actual situation. This utility model does not limit this.

[0080] In other embodiments, multiple fixing parts can be provided as needed, as long as they can fix the connecting pipe assembly 2.

[0081] In other embodiments, multiple cutouts 14 can be provided on the pad 1 as needed, which can reduce the weight of the pad 1, save materials, and thus save production costs.

[0082] In this embodiment, the pad 1 is made of cardboard or corrugated board. In other embodiments, the pad 1 may also be made of foam material. This utility model does not limit this.

[0083] This utility model places the connecting pipe assembly 2 on the pad 1, and restricts the pipe joint nut 22 of the connecting pipe assembly 2 by the limiting part 11, so as to prevent the pipe joint nut 22 from leaking out of the pad 1 and causing the fins to bump or bend. The baffle 12 blocks the connecting pipe assembly 2 in the circumferential direction to prevent the connecting pipe 21 from leaking out of the pad 1 and being scratched. Furthermore, the integrated sealing sleeve covers the pad 1 and the connecting pipe assembly 2 inside, so that the pad 1 no longer contacts the fins, thus eliminating the problem of the pad corroding the fins. Moreover, the process of placing the pad 1 is moved forward, reducing the transportation steps and improving the overall efficiency.
