Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to an anti-slope device for pre-embedded air conditioning pipes. Background Technology

[0002] Air conditioning pipes are a crucial component of air conditioning systems, playing a key role in transporting refrigerant, condensate, and other media. Their performance directly affects the operating efficiency and lifespan of the air conditioner.

[0003] In existing technology, air conditioning pipes generally consist of refrigerant pipes and condensate pipes. The refrigerant pipes are primarily made of copper. A vacuum is required inside the copper pipes to remove air and prevent moisture buildup. These pipes connect the indoor and outdoor units, forming a closed system for transporting refrigerant (such as Freon). In cooling mode, the low-temperature, low-pressure refrigerant is discharged outdoors through the thicker pipe, compressed by the compressor into a high-temperature, high-pressure gas, and then returns indoors through the thinner pipe, typically using specialized seamless copper tubing. The condensate pipes are responsible for draining the condensate produced by the indoor unit, preventing water accumulation.

[0004] The condensate drain pipe needs to drain excess condensate, requiring a certain slope to prevent backflow. Existing standard air conditioners are not installed with pre-embedded structures; instead, holes are drilled in the exterior wall, and the condensate drain pipe is wrapped together with the refrigerant copper pipe before being directly passed through the hole and connected to the outdoor unit. This method demands more skill from the operator; improper operation can easily result in the condensate drain pipe lacking a proper slope at the hole, forming a water trap that can breed bacteria or corrode the structure. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-backslope device for pre-embedded air conditioning pipes. By setting a pre-embedded sleeve, installation holes for air conditioning pipes can be reserved during construction, reducing the need for drilling later and playing a good role in preventing backslopes.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An anti-backflow device for pre-embedded air conditioning pipes includes an inner sleeve and an outer shell. The inner sleeve has a hollow perforation and an eccentric perforation, which are respectively installed on mounting plates on both sides of the outer shell. Multiple connecting brackets are provided between the two mounting plates, and the connecting brackets are connected to different positions of the structural steel bars at intervals. The eccentric perforation is an inclined hole, and the distance from the axis on the side of the eccentric perforation closer to the wall is smaller than the distance from the axis on the side closer to the wall. An insulation layer is provided between the inner sleeve and the outer shell.

[0008] Furthermore, the mounting docking plate is provided with multiple bolt holes.

[0009] Furthermore, multiple connecting screws pass through the mounting docks, and the connecting screws pass through bolt holes on the mounting docks respectively.

[0010] Furthermore, the connecting bracket includes an annular disk, a connecting arm arranged along the annular disk, and a connecting port provided at the end of the connecting arm.

[0011] Furthermore, the annular disk is provided with multiple threaded holes that are adapted to the connecting screw.

[0012] Furthermore, both ends of the hollow perforation and the eccentric perforation are provided with detachable plugs.

[0013] Compared with existing technologies, the advantages of this utility model are as follows: First, the utility model has a simple structure and is easy to implement. By pre-reserving air conditioning holes during concrete pouring, the problem of perforation of the external wall is avoided later, reducing illegal operations during construction work through the external wall and preventing damage to the main steel reinforcement. Second, by setting hollow and eccentric perforations for installing and connecting the air conditioning condensate pipe and refrigerant copper pipe respectively, the two do not interfere with each other, and the pre-set slope ensures the drainage stability of the condensate pipe.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0020] In the description of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] Furthermore, the terms "first," "second," and "third" are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance.

[0022] Furthermore, the use of terms such as "horizontal," "vertical," and "suspended" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0023] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" 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 or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0025] like Figure 1As shown, an anti-backflow device for an air conditioning pipe includes an inner sleeve and an outer shell 1. The inner sleeve has a hollow perforation 2 and an eccentric perforation 3, respectively installed on mounting plates 4 on both sides of the outer shell 1. Multiple connecting brackets 5 are arranged between the two mounting plates 4, and the connecting brackets 5 are connected to different positions of the structural reinforcing bars at intervals. The eccentric perforation 3 is an inclined hole, and the distance from the axis on the side closer to the wall is less than the distance from the axis on the side closer to the wall. An insulation layer is provided between the inner sleeve and the outer shell 1. Specifically, the insulation layer can be a foam layer fixed between the inner sleeve and the outer shell, or it can be other similar filling materials.

[0026] Compared to existing technologies, where only air conditioning holes for split-type air conditioner outdoor units are pre-drilled during building construction, these holes are often created by drilling angled holes in the exterior wall. However, due to aesthetic considerations, these pre-drilled holes are unsuitable for the air conditioner's installation location, necessitating re-drilling. This process, often done improperly, frequently results in holes being drilled in load-bearing walls, creating safety hazards. This invention provides a pre-embedded pipe that can be installed during the early stages of concrete pouring, following the building construction process. Multiple devices can be spliced ​​together as needed. When splicing multiple devices, the height of the different pipes needs to be adjusted so that the lower opening of the eccentric perforation 3 of the previous device connects to the higher opening of the eccentric perforation 3 of the next device. This ensures the slope of the eccentric perforation 3 is greater than 1 degree, guaranteeing proper drainage of condensate.

[0027] The mounting docking plate 4 is provided with multiple bolt holes. Multiple connecting screws pass through the mounting docking plates 4, and the connecting screws pass through the bolt holes on the mounting docking plates 4 respectively.

[0028] The connecting bracket 5 includes an annular disc, a connecting arm 6 arranged along the annular disc, and a connecting port 7 at the end of the connecting arm 6. The connecting arm 6 can be fixed by passing the reinforcing bars through the connecting port 7 during the binding of the reinforcing bars. Alternatively, the connecting port 7 can be directly tied to the reinforcing bar structure using wire, binding tape, etc., to prevent displacement during concrete pouring. Of course, the connecting port 7 can also be directly welded to the reinforcing bar structure. Before welding, rust and dirt on the surface of the embedded pipe and the reinforcing bars need to be cleaned to ensure welding quality, and the welding temperature and time should be controlled to avoid thermal damage to the embedded pipe.

[0029] The annular disk is provided with multiple threaded holes that are adapted to the connecting screw.

[0030] Both ends of the hollow perforation 2 and the eccentric perforation 3 are equipped with removable plugs. By using removable plugs, the airtightness of the hollow perforation 2 and the eccentric perforation 3 can be ensured, preventing concrete or other impurities from entering the hollow perforation 2 and the eccentric perforation 3 during the pouring process and causing pipe blockage. Multiple layers of sealing can also be performed before pouring, and the pipes must be purged with a high-pressure air gun after completion.

[0031] In practical use, the hollow perforation 2 should be fitted with the air conditioning refrigerant copper pipe, with a gap of 5-10mm between them. After connecting the air conditioning refrigerant copper pipe, the joint should be glued or filled with other sealant. If there are bends, elbows should be used for connection to prevent the copper pipe from bending.

[0032] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
