Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.
[0033] This application provides a fixing structure to solve the problem of difficulty in adapting pipelines to fixing structures. The following description will be provided in conjunction with the accompanying drawings.
[0034] In the embodiments of this application, such as Figure 1 As shown, this fixing structure includes:
[0035] First fixed shell 1;
[0036] A second fixed shell 2, one end of which is movably connected to one end of a first fixed shell 1, and the first fixed shell 1 and the second fixed shell 2 are movably brought close together to form a receiving cavity 5, which is used for the passage of a pipe 7; and
[0037] Sealing part 3 is disposed within receiving cavity 5;
[0038] The sealing part 3 is formed by the curing of sealant filled between the pipe 7 and the side wall of the receiving cavity 5. The sealing part 3 fixes the first fixing shell 1, the second fixing shell 2 and the pipe 7 together.
[0039] It should be noted that sealant refers to a sealing material that deforms to conform to the shape of the sealing surface, does not easily flow, can cure, and has a certain degree of adhesion. In this embodiment, any known sealing material can be selected, as long as it meets the above characteristics.
[0040] "One end of the second fixed shell 2 is movably connected to one end of the first fixed shell 1" means that one end of the second fixed shell 2 and one end of the first fixed shell 1 can be connected by rotation, sliding, elastic connection, or a combination of the above methods to change the relative positional relationship between the first fixed shell 1 and the second fixed shell 2. Through this movable method, when the first fixed shell 1 and the second fixed shell 2 tend to move away from each other, the pipe 7 can be embedded between the first fixed shell 1 and the second fixed shell 2. Then, the first fixed shell 1 and the second fixed shell 2 are brought closer together to enclose the pipe 7, which passes through the receiving cavity 5. Subsequently, sealant is filled into the receiving cavity 5. The sealant, with its certain fluidity, can adapt to the shape of the receiving cavity 5 and the shape of the pipe 7, thus deforming and fully filling the space between the side wall of the receiving cavity 5 and the pipe 7. Once the sealant has cured, the pipe 7 is fixed.
[0041] The end of the first fixing shell 1 away from the second fixing shell 2 and the end of the second fixing shell 2 away from the first fixing shell 1 can be detachably connected, or they can be not connected and only fixed by the sealing part 3.
[0042] Understandably, by simply enlarging the receiving cavity 5 within a reasonable range, pipes 7 of different diameters can be passed through the receiving cavity 5 and kept at a distance from the side wall of the receiving cavity 5. After the sealant is filled and cured, the pipes 7 are fixed, demonstrating high assembly adaptability. Furthermore, it is also possible to fix multiple pipes 7 with different diameters.
[0043] Depending on the fixed position of the pipe 7, the first fixing shell 1 and the second fixing shell 2 can be configured with different shapes. For example, when the fixed position of the pipe 7 is a straight section of the pipe 7, the receiving cavity 5 is configured as a cylinder; correspondingly, one end of the second fixing shell 2 can be rotatably connected to one end of the first fixing shell 1, and the first fixing shell 1 and the second fixing shell 2 surround or move away from the pipe 7 in an open-closed manner; alternatively, both the first fixing shell 1 and the second fixing shell 2 are configured as arc-shaped plate structures, with the second fixing shell 2 slidably connected to the outer surface of the first fixing shell 1, and the sliding path of the second fixing shell 2 is curved. For example, when the fixed position of the pipe 7 is a curved section of the pipe 7, the receiving cavity 5 is configured as an L-shape, and correspondingly, one end of the second fixing shell 2 can be rotatably connected to one end of the first fixing shell 1, and the first fixing shell 1 and the second fixing shell 2 surround or move away from the pipe 7 in an open-closed manner.
[0044] For example, the thickness of the movable connection between the first fixed shell 1 and the second fixed shell 2 can be made thinner, and the movable connection can be made of a material with a certain stress. The relative movement between the first fixed shell 1 and the second fixed shell 2 can be achieved by bending the movable connection.
[0045] In some embodiments, the sealant is a moisture-curing sealant.
[0046] It should be noted that moisture-curing sealants refer to sealants that cure upon contact with moisture in the air. This means that once the sealant is applied, it can cure after being left in the working environment for a period of time, resulting in lower production costs.
[0047] In some embodiments, the sealant includes one of polyurethane sealant and silicone sealant.
[0048] It should be noted that polyurethane sealant refers to a sealant whose main components are polyurethane rubber and polyurethane prepolymer. In this embodiment, a moisture-curing polyurethane sealant is used, which cures by contact with water in the air. Silicone sealant refers to a paste-like substance made by mixing polydimethylsiloxane as the main raw material with crosslinking agents, fillers, plasticizers, coupling agents, and catalysts under vacuum. It cures by reacting with water in the air to form elastic silicone rubber.
[0049] It is understandable that the sealant can also be any known moisture-curing sealant other than polyurethane sealant and silicone sealant. When selecting the sealant, the materials of the pipe 7 to be fixed, the first fixing shell 1 and the second fixing shell 2 need to be considered to avoid the sealant reacting with the above structures.
[0050] In some embodiments, such as Figure 2 and Figure 3 As shown, the end of the first fixed shell 1 away from the second fixed shell 2 is detachably connected to the end of the second fixed shell 2 away from the first fixed shell 1.
[0051] It should be noted that detachable connections include various common methods such as bolt connections, snap-fit connections, pin connections, and adhesive bonding. Understandably, connecting the first fixing shell 1 and the second fixing shell 2 using these detachable connection methods reduces the amount of sealant overflowing from the receiving cavity 5 during the application and curing processes. Furthermore, it ensures the fixed volume of the receiving cavity 5 during curing, preventing sealant leakage from affecting the fixing effect.
[0052] In some embodiments, such as Figure 2 As shown, the first fixing shell 1 is provided with a first baffle 11 on both sides, and the second fixing shell 2 is provided with a second baffle 21 on both sides. Along the direction from the first fixing shell 1 to the second fixing shell 2, the first baffle 11 and the second baffle 21 are arranged at intervals relative to each other.
[0053] It should be noted that the two sides of the first fixed shell 1 refer to the two sides of the first fixed shell 1 that are not connected to the second fixed shell 2. The two sides of the first fixed shell 1 can be parallel sides, or one side can be an L-shaped structure and the other side can be a relatively larger L-shaped structure. The second fixed shell 2 is similar. When the first fixed shell 1 and the second fixed shell 2 approach each other to form the receiving cavity 5, the first baffle 11 and the second baffle 21 are corresponding to each other and are spaced apart.
[0054] Understandably, the flow of sealant is restricted by the first baffle 11 and the second baffle 21 so that the cavity 5 is filled with sealant as much as possible.
[0055] In some embodiments, such as Figure 2 As shown, one end of the first fixed shell 1 is provided with a buckle 12, and one end of the second fixed shell 2 is provided with a slot 22. The buckle 12 is used to snap into the slot 22.
[0056] In some embodiments, such as Figure 4 As shown, both the first fixed shell 1 and the second fixed shell 2 are made of flexible materials.
[0057] It should be noted that flexible materials refer to materials with good flexibility and adaptability. Understandably, in air conditioning systems, there may be situations where the fixed positions of adjacent pipes 7 are inconsistent. External force is used to deform the first fixing shell 1 and the second fixing shell 2 to adapt to the direction of the pipes 7, further improving the fixation adaptability of the fixing structure. Once the sealant has cured, the deformed shapes of the first fixing shell 1 and the second fixing shell 2 can be fixed. Specifically, when two pipes 7 are arranged in a crisscrossing pattern, the two ends of the first fixing shell 1 and the second fixing shell 2 can be twisted in opposite directions to make the shape of the receiving cavity 5 adapt to the direction of the pipes 7.
[0058] In some embodiments, the flexible material includes nitrile rubber.
[0059] It should be noted that nitrile rubber refers to a copolymer polymerized from acrylonitrile and butadiene monomers. Of course, other known materials that are not readily reactive with sealants can also be used. Understandably, when filling with sealant, the first fixing shell 1 and the second fixing shell 2 made of nitrile rubber will not react with the sealant, exhibiting good chemical stability.
[0060] In some embodiments, such as Figure 4 As shown, the fixing structure also includes a telescopic fixing member 6, which is used to telescopically fit over the first fixing shell 1 and the second fixing shell 2.
[0061] It should be noted that the telescopic fastener 6 refers to a structure that deforms by telescopic expansion to be fitted over the first fixed shell 1 and the second fixed shell 2, and can continuously bring the first fixed shell 1 and the second fixed shell 2 closer to each other.
[0062] Understandably, the telescopic fastener 6 is adjusted to fit over the first and second fixed shells 1 and 2, based on the size of the outer perimeter after the first fixed shell 1 and the second fixed shell 2 are closed. Subsequently, the telescopic fastener 6 is adjusted to tighten the first and second fixed shells 1 and 2. Furthermore, during the filling of sealant and while waiting for the sealant to cure, a continuous external force needs to be applied to the first and second fixed shells 1 and 2 to prevent unwanted deformation. For example, the telescopic fastener 6 can be a cable tie, a rubber sleeve, etc.
[0063] For example, when both the first fixed shell 1 and the second fixed shell 2 are made of flexible materials and are fixed by telescopic fasteners 6, the thickness of the movable connection between the first fixed shell 1 and the second fixed shell 2 can be made thinner, and no connection structure is provided at the end of the first fixed shell 1 away from the movable connection and the end of the second fixed shell 2 away from the movable connection, so as to better adapt to the deformation of the first fixed shell 1 and the second fixed shell 2.
[0064] In some embodiments, such as Figure 2 , Figure 3 as well as Figure 4 As shown, the first fixed shell 1 and / or the second fixed shell 2 are provided with a plurality of vent holes 4.
[0065] Understandably, the vent holes 4 increase the surface area of the sealant in contact with air, thereby accelerating the curing and molding speed of the sealant. For example, the diameters of the multiple vent holes 4 may be the same or different.
[0066] This application also provides an air conditioner, which includes a pipe 7 and at least one of the above-described fixing structures. The specific structure of the fixing structure is as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0067] It should be noted that air conditioning can refer to indoor air conditioning unit, outdoor air conditioning unit, or air conditioner. Air conditioners can include wall-mounted air conditioners, floor-standing air conditioners, ducted air conditioners, and central air conditioning systems.
[0068] In some embodiments, the air conditioner also includes some well-known conventional components, such as heat exchangers, fans, etc.
[0069] In the above embodiments, the descriptions of each embodiment have different focuses. Parts not described in detail in a particular embodiment can be referred to in the relevant descriptions of other embodiments. In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more features.

Therefore, the content of this specification should not be construed as a limitation of this application.
