Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0019] Example 1: See Figures 1 to 4 As shown, this utility model provides an embodiment of a tube positioning component.

[0020] The tube positioning component 1 includes at least one arc-shaped wrapping part 11, wherein the arc-shaped wrapping part 11 is provided with a first fitting part 12, a first elastic buckle 13 and a blocking part 14; The first fitting part 12 is provided on the inner surface of the arc-shaped wrapping part 11. The fitting direction of the first fitting part 12 is consistent with the radial direction of the arc-shaped wrapping part 11. The first fitting part 12 is a concave structure or an convex structure. The fastening direction of the first elastic buckle 13 is consistent with the axial direction of the arc-shaped wrapping part 11. When the first elastic buckle 13 is fastened, it can adaptively switch between the first state and the second state. When the tube positioning component is installed, the first elastic buckle 13 is deformed from the first state to the second state under pressure, and the height of the protrusion from the arc-shaped wrapping part 11 is reduced. After installation, the first elastic buckle 13 returns to the first state. The aforementioned blocking part 14 is provided on the outer surface of the aforementioned arc-shaped wrapping part 11 and is located behind the aforementioned first elastic buckle 13 along the fastening direction. The aforementioned blocking part 14 is an outwardly convex structure.

[0021] In the above text, the arc-shaped wrapping part 11 refers to a support member with a curved profile. Its concave side surface is its inner surface. The inner surface of the arc-shaped wrapping part 11 is the tube contact surface, which is in direct contact with the tube to achieve wrapping of the tube. The arc-shaped wrapping part 11 is set in an arc shape so that the tube positioning part 1 and the tube can fit together when they move relative to each other in the radial direction.

[0022] The first fitting part 12 is located on the inner surface of the arc-shaped wrapping part 11. The fitting direction is consistent with the radial direction of the arc-shaped wrapping part 11. The radial direction refers to the direction pointing towards or away from the center of the arc-shaped wrapping part 11 (or the central axis of the tube body) as the origin. That is to say, the first fitting part 12 of the tube body positioning member 1 and the second fitting part on the tube body can be fitted together when they move relative to each other along their radial directions. When the first fitting part 12 is a concave structure, the second fitting part on the tube body is a convex structure; when the first fitting part 12 is a convex structure, the second fitting part on the tube body is a concave structure.

[0023] The first elastic buckle 13 is a cantilever buckle, and its engagement direction is consistent with the axial direction of the arc-shaped wrapping part 11. The axial direction refers to the direction along the central axis of the arc-shaped wrapping part 11. That is to say, the first elastic buckle 13 on the tube positioning part 1 and the mounting hole can engage with each other when they move relative to each other along their axial directions. During the engagement process, the first elastic buckle 13 can adaptively switch between the first state and the second state (without additional operation, automatically triggered by the squeezing or releasing of the external structure). The state switching is achieved through elastic deformation. The larger deformation Δ2>Δ1 ensures that the buckle can pass smoothly through the obstruction of the external structure, and the height difference is used to achieve locking and prevent loosening.

[0024] The blocking part 14 is located on the outer surface of the arc-shaped wrapping part 11. The blocking part 14 is located behind the first elastic buckle 13 along the fastening direction. That is, before the first elastic buckle 13 is fastened with the mounting hole, the blocking part 14 is located on the side of the first elastic buckle 13 away from the mounting hole. After the first elastic buckle 13 is fastened with the mounting hole, the blocking part 14 and the first elastic buckle 13 are located on both sides of the mounting hole, and the tube positioning member 1 is clamped on the end face of the mounting hole by the first elastic buckle 13 and the blocking part 14. The blocking part 14 has an outward convex structure, and achieves the blocking and limiting function through its own protrusion.

[0025] Specifically, when the first elastic buckle 13 is in its first state, its deformation is Δ1, and its height protruding from the outer surface of the arc-shaped wrapping part 11 is H1, which is greater than a preset value. When the first elastic buckle 13 is in its second state, its deformation is Δ2, and its height protruding from the outer surface of the arc-shaped wrapping part 11 is H2, where Δ2 > Δ1 and H2 is not greater than the preset value. The height of the blocking part 14 protruding from the outer surface of the arc-shaped wrapping part 11 is H3, which is greater than the preset value. Both H1 and H3 need to be greater than the preset values ​​to ensure that the first elastic buckle 13 and the blocking part 14 in the first state can contact the end face of the mounting hole. H2 is not greater than the preset value to ensure that the first elastic buckle 13 in the second state can pass through the mounting hole.

[0026] When the tube positioning component 1 is fitted onto the tube body, the first fitting portion 12 engages with the second fitting portion on the outer wall of the tube body, preventing axial relative movement between the tube positioning component and the tube body. As the tube body and tube positioning component 1 enter the mounting hole axially, the first elastic buckle 13 is compressed and deformed to a second state, reducing its height to pass through the mounting hole. After passing through the mounting hole, the first elastic buckle 13 returns to its first state, increasing its height and forming an axial lock on one side of the mounting hole. The blocking portion 14 forms a physical block on the other side of the mounting hole, thereby preventing axial relative movement between the tube positioning component 1 and the mounting hole.

[0027] The above technical solution provides a pipe positioning component comprising an arc-shaped wrapping portion, a first fitting portion, a first elastic buckle, and a blocking portion. The arc-shaped wrapping portion conforms to the outer side of the pipe body. The first fitting portion restricts the axial relative displacement between the positioning component and the pipe body. The first elastic buckle and the blocking portion restrict the axial relative displacement between the pipe body and the mounting hole, thereby limiting the axial displacement between the pipe body and the mounting hole. During pipe installation, welding and screw connections are unnecessary, achieving low-cost, non-destructive, efficient, and detachable pipe installation.

[0028] In this embodiment, the first fitting portion 12 is an arc-shaped groove or arc-shaped protrusion extending along the arc length direction of the arc-shaped wrapping portion 11, and the blocking portion 14 is an arc-shaped protrusion extending along the arc length direction of the arc-shaped wrapping portion 11.

[0029] In the above text, the length direction of the arc-shaped groove is consistent with the arc length direction of the arc-shaped wrapping part, and the length direction of the arc-shaped protrusion is consistent with the arc length direction of the arc-shaped wrapping part.

[0030] Specifically, the first fitting portion 12 extends along the arc length direction of the arc-shaped wrapping portion 11, so that when the arc-shaped wrapping portion 11 wraps around the outside of the tube body, the contact area between the first fitting portion 12 and the second fitting portion on the outer wall of the tube body is large. The blocking portion 14 extends along the arc length direction of the arc-shaped wrapping portion 11, so that when the tube body positioning member 1 extends into the mounting hole, the contact area between the blocking portion 14 and the end face of the mounting hole is large.

[0031] Through the above technical solution, the first fitting part is an arc-shaped groove or an arc-shaped protrusion, and the blocking part is an arc-shaped protrusion, which eliminates local stress concentration and improves connection stability.

[0032] In this embodiment, the front end of the first elastic buckle 13 along the fastening direction is connected to the arc-shaped wrapping part 11, and the rear end of the first elastic buckle 13 along the fastening direction is suspended.

[0033] In the above text, the first elastic buckle 13 and the arc-shaped wrapping part 11 form a fixed connection at the starting end of the fastening movement. That is to say, before the first elastic buckle 13 is fastened to the mounting hole, the end of the first elastic buckle 13 facing the mounting hole is connected to the material of the arc-shaped wrapping part 11, and the part of the first elastic buckle 13 away from the mounting hole is a free end, which remains unrestrained.

[0034] Specifically, when the first elastic buckle 13 engages, its fixed end initially contacts the wall of the mounting hole. As the first elastic buckle 13 enters the mounting hole, its suspended end gradually swings radially inward toward the arc-shaped wrapping portion 11. Once the first elastic buckle 13 is in position, its engagement position is now located on the other side of the mounting hole and is no longer restricted by the inner wall of the mounting hole. Therefore, the engagement position of the first elastic buckle 13 rebounds, thus pressing against the end face of the mounting hole opening.

[0035] With the above technical solution, after the first elastic buckle is engaged, its two ends abut against the end face of the opening and the arc-shaped wrapping part respectively. The first elastic buckle is subjected to forces in two opposite directions, making the engagement of the first elastic buckle more reliable.

[0036] In this embodiment, the tube positioning member 1 includes two arc-shaped wrapping portions 11. Each arc-shaped wrapping portion 11 has a first end and a second end facing away from each other in the arc length direction. The concave sides of the two arc-shaped wrapping portions 11 are opposite to each other, the first ends of the two arc-shaped wrapping portions 11 are opposite to each other, and the second ends of the two arc-shaped wrapping portions 11 are opposite to each other.

[0037] In the above text, the first end and the second end of the arc-shaped wrapping portion 11 refer to the two side boundaries of the arc-shaped wrapping portion 11 along the arc length direction, which are used to define the docking position of the two arc-shaped wrapping portions 11. The concave sides facing each other means that the curved inner surfaces of the two arc-shaped wrapping portions 11 are symmetrically distributed, forming an annular wrapping space to adapt to the outer diameter of the tube.

[0038] Specifically, when the concave sides of the two arc-shaped wrapping parts 11 form a closed ring structure to wrap the tube, the concave sides of the two arc-shaped wrapping parts 11 contact the outer wall of the tube to generate a radial clamping force.

[0039] The above technical solution uses two arc-shaped wrapping parts 11 to clamp the tube body and apply symmetrical pressure to keep the tube body centered.

[0040] In this embodiment, the tube positioning component 1 further includes a flexible connecting part 15, which connects the first ends of the two arc-shaped wrapping parts 11. One of the aforementioned arc-shaped wrapping parts 11 has a first insertion part 16 at its first end, and the other of the aforementioned arc-shaped wrapping parts has a second insertion part 17 at its first end. The first insertion part 16 and the second insertion part 17 are detachably connected.

[0041] In the above text, the flexible connection part 15 refers to a connecting component with bendable characteristics, which is used to allow relative displacement within a certain range while maintaining the relative position of the two arc-shaped wrapping parts 11. The first insertion part 16 and the second insertion part 17 switch the connection state through insertion and withdrawal actions, which are used to form a temporary positioning reference for the two arc-shaped wrapping parts 11 during the assembly process and maintain the pre-assembled state.

[0042] Specifically, during installation, the flexible connector 15 compensates for the positional deviation between the two arc-shaped wrapping parts 11 through its own deformation, enabling the two arc-shaped wrapping parts 11 to adapt to the adjustment requirements of different installation angles. When the first insertion part 16 and the second insertion part 17 are inserted into each other, the two arc-shaped wrapping parts 11 are restricted to a preset relative position, ensuring that the arc-shaped wrapping parts 11 remain stable before being fully locked.

[0043] Through the above technical solution, by combining the flexible connecting part, the first insertion part and the second insertion part, the tube positioning component can be quickly positioned and reliably connected without welding.

[0044] In this embodiment, the flexible connecting part 15 is a flexible strip, and the two ends of the flexible strip are respectively connected to the outer surfaces of the two arc-shaped wrapping parts 11.

[0045] In the above text, the flexible connection part 15 refers to a strip-shaped component with elastic deformation capability, which can be implemented by rubber strip or silicone strip, and can adapt to the relative displacement of the arc-shaped wrapping part 11 through its own bending deformation during installation.

[0046] Specifically, the two ends of the flexible strip are fixed to the outer surface of the arc-shaped wrapping part 11 by adhesive or snap-fit. When the two arc-shaped wrapping parts 11 surround the outer periphery of the tube, the flexible connecting part 15 is in an arc-shaped state. When the two arc-shaped wrapping parts 11 are removed from the outer periphery of the tube, the flexible connecting part 15 can be in a straight state or other states.

[0047] The above technical solution achieves the pre-connection of two arc-shaped wrapping parts through a flexible strip. The flexible strip has a simple structure and is easy to realize the shape of the outer circle of the tube positioning component, which facilitates the connection of the tube positioning component to the mounting hole.

[0048] In this embodiment, of the first plug-in portion 16 and the second plug-in portion 17, one is a plug-in piece and the other is a plug-in groove.

[0049] In the above text, the insert plate refers to the sheet-like protrusion structure provided at the end of one of the arc-shaped wrapping parts 11, and the insert groove refers to the groove structure provided at the end of the other arc-shaped wrapping part 11. The outer diameter of the insert plate and the inner diameter of the insert groove form a clearance fit or an interference fit.

[0050] Specifically, when the two arc-shaped wrapping parts 11 need to be connected, the plug of one arc-shaped wrapping part 11 is inserted into the plug groove of the other arc-shaped wrapping part 11, so that a rigid connection is formed between the first ends of the two arc-shaped wrapping parts 11.

[0051] Through the above technical solution, after the plug-in piece and the plug-in slot are plugged into each other, they achieve self-locking through complementary geometry. At the same time, the first plug-in part and the second plug-in part can be reused.

[0052] In this embodiment, one of the arc-shaped wrapping parts 11 has a second elastic buckle 18 at its second end, and the other arc-shaped wrapping part 11 has a slot 19 at its second end. The second elastic buckle 18 and the slot 19 are detachably fastened together.

[0053] In the above text, the second elastic buckle 18 refers to a fastening component with elastic deformation capability located at the second end of the arc-shaped wrapping part 11. Specifically, it can be implemented using a cantilever beam structure or a hook-like structure, and its material can be elastic plastic or metal. The slot 19 refers to a recessed or through-hole structure that matches the shape of the second elastic buckle 18, and can be formed by injection molding or machining. The engagement and disengagement of the second elastic buckle 18 and the slot 19 are achieved through elastic deformation, allowing connection or disassembly without the need for external tools.

[0054] Specifically, when the second ends of the two arc-shaped wrapping parts 11 approach each other, the second elastic buckle 18 is compressed and undergoes elastic deformation until it is inserted into the slot 19 and then returns to its original shape, forming a snap-fit ​​connection. To disassemble, the two arc-shaped wrapping parts 11 can be separated by pressing or moving the second elastic buckle 18 to disengage it from the slot 19. This connection method, through the combination of elastic deformation and mechanical limiting, ensures structural stability in the closed state while also enabling quick assembly and disassembly.

[0055] The above technical solution, through the cooperation of elastic buckles and slots, allows operators to complete installation or disassembly by hand, avoiding the thermal stress caused by welding, and eliminating the risk of screws loosening or stripping.

[0056] Example 2: See Figures 5 to 9 As shown, this utility model provides an embodiment of an indoor air conditioning unit.

[0057] The indoor unit of an air conditioner includes: Water pipe 2, with a second fitting part 21 on the outer side of the water outlet; The housing 3 has an inner wall facing the interior of the air conditioner indoor unit, an outer wall opposite to the inner wall, and a mounting hole penetrating the inner wall and the outer wall. The pipe positioning component 1 is attached to the outside of the water outlet of the water pipe 2 and passes through the mounting hole. The first fitting part 12 and the second fitting part 21 are in concave-convex cooperation. The blocking part 14 abuts against the inner wall of the housing 3. The first elastic buckle 13 abuts against the outer wall of the housing 3.

[0058] In the above text, the second fitting part 21 refers to the protrusion or recess structure provided on the outer surface of the water pipe, which is used to form a radial fit with the inner or outer concave structure of the pipe positioning member 1. The mounting hole refers to the through hole that penetrates the wall of the housing 3. The hole diameter can be slightly larger than the outer diameter of the pipe positioning member 1, so that the pipe positioning member 1 can pass through the mounting hole to complete the assembly, while providing space for the deformation of the first elastic buckle 13.

[0059] Specifically, the water pipe 2 is fitted to the inside of the pipe positioning component, and the two are radially positioned through the interlocking of the second fitting part 21 and the first fitting part 12. During installation, the pipe positioning component 1 carries the water pipe 2 through the mounting hole of the housing 3 from the inside. The blocking part 14 contacts the inner wall of the housing 3 to form an axial stop, preventing the water pipe 2 from moving further inward. The first elastic buckle 13 undergoes elastic deformation when passing through the mounting hole, and returns to its original shape after completely passing through the mounting hole. Its protruding part contacts the outer wall of the housing 3 to form a reverse limit. During disassembly, after pressing the first elastic buckles on both sides, the pipe positioning component is pushed towards the inside of the housing 3 to disassemble the pipe.

[0060] Through the above technical solution, the arc-shaped wrapping part, the first fitting part, the first elastic buckle, and the blocking part work together to allow the arc-shaped wrapping part to conform to the outer side of the pipe body. The first fitting part restricts the axial relative displacement between the pipe body positioning component and the pipe body, while the first elastic buckle and the blocking part restrict the axial relative displacement between the pipe body and the mounting hole, thereby limiting the axial displacement between the pipe body and the mounting hole. During pipe installation, welding and screw connections are unnecessary, achieving low-cost, non-destructive, efficient, and detachable water pipe installation.

[0061] In this embodiment, the water pipe 2 is a copper pipe, and the second fitting part 21 is an annular protrusion formed by forging.

[0062] In the above text, copper pipe refers to a tubular structure made of metallic copper, which can be produced by extrusion molding or drawing processes. Its corrosion resistance and ductility can meet the requirements of air conditioning water transmission. The annular protrusion refers to a protruding structure continuously distributed along the circumference of the copper pipe. It can be formed by local extrusion on the surface of the copper pipe through cold forging. This structure can form a radial fit with the fixing parts without welding or additional parts.

[0063] Specifically, an annular protrusion is formed directly on the outer side of the copper pipe outlet through a cold forging process, and this protrusion is in concave-convex fit with the first fitting part 12 of the pipe body positioning part 1.

[0064] The above technical solution allows for the direct fabrication of the interlocking structure on the surface of the copper tube using a cold heading process, eliminating the need for welding and screw assembly. During installation, positioning can be achieved simply by interlocking the annular protrusion with the fastener.

[0065] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
