Technical Field

[0001] This application relates to the field of air conditioning ducts, and in particular to an insulation structure and an air conditioning duct. Background Technology

[0002] Air conditioning ducts are pipes used in air conditioning systems to transport air, delivering cooled or heated air processed by the air conditioning unit to various areas within a building that require temperature regulation. This helps to regulate indoor temperature, create a comfortable indoor environment, promote indoor air circulation, expel stale air, introduce fresh air, ensure indoor air quality, meet people's breathing needs, and maintain a good indoor air environment.

[0003] A search revealed a Chinese patent document (publication number: CN215571115U) that discloses an insulation structure for air conditioning ducts, but it still has the following drawbacks:

[0004] Although the insulation structure used for the aforementioned air conditioning ducts utilizes B1-grade flame-retardant PIR insulation pads with a better fire resistance rating, and because there are no pre-made insulation pads for B1-grade materials, the problem of powder from on-site processing is solved, thus improving the insulation quality, there are still some issues in places with complex building structures or limited spaces, such as narrow ceiling mezzanines or equipment rooms, where the air conditioning ducts may be squeezed, leading to adverse effects on ventilation, air conditioning performance, equipment lifespan, energy consumption, and safety. Utility Model Content

[0005] In order to improve the problem that air conditioning ducts are squeezed in some places with complex building structures or limited space, such as narrow ceiling mezzanines and equipment rooms, which leads to adverse effects on ventilation, air conditioning performance, equipment life, energy consumption and safety, this application provides an insulation structure and an air conditioning duct.

[0006] The thermal insulation structure and air conditioning duct provided in this application adopt the following technical solution:

[0007] A thermal insulation structure includes a first flexible shell, a second flexible shell installed at one end of the first flexible shell, thermal insulation cotton installed on the inner sidewalls of both the first and second flexible shells, flexible sleeves installed through the interior of the thermal insulation cotton at equal intervals, and guide steel wires installed inside the flexible sleeves, and wrapping balloons installed on the other outer wall of the thermal insulation cotton.

[0008] By adopting the above technical solutions, the air conditioning duct body is insulated and protected by insulation cotton and a wrapping balloon, and its toughness is effectively improved by wrapping balloon and guide steel wire.

[0009] Preferably, the outer side wall of the encapsulating balloon away from the insulation cotton is tightly fitted with silicone anti-slip pads.

[0010] By adopting the above technical solution and using the silicone anti-slip pad, the adhesion of the wrapped balloon surface is further improved.

[0011] Preferably, the outer side walls of the first flexible shell and the second flexible shell are symmetrically equipped with connecting frames, the outer side walls of the connecting frames are symmetrically equipped with connecting blocks, and the outer side walls of the connecting blocks are equipped with limit blocks.

[0012] By adopting the above technical solution, the connecting frame is positioned relative to the connecting blocks and then fixed in a limiting manner.

[0013] Preferably, the outer side wall of the connecting block is provided with first abutting protrusions at equal intervals, and the outer side wall of the first abutting protrusion abuts against the outer side wall of the second abutting protrusion.

[0014] By adopting the above technical solution, the outer wall of the first contacting protrusion abuts against the outer wall of the second contacting protrusion, thereby limiting and fixing the mounting sleeve.

[0015] Preferably, the second abutting protrusions are installed at equal intervals on one side of the outer wall of the flexible sheet, and the flexible sheet is symmetrically installed inside the mounting sleeve, which is inserted into the outside of two mating connecting blocks.

[0016] By adopting the above technical solution, the connection between the two connecting brackets is limited by the installation sleeve.

[0017] Preferably, a first connecting block is installed on the outer side wall of the connecting frame, and a series post is inserted inside the first connecting block. The other end of the series post is inserted inside the second connecting block, and the second connecting blocks are symmetrically installed on the outer side wall of the connecting ring. Two limiting sleeves are fitted on the outer side wall of each series post, and the outer side wall of the limiting sleeve abuts against the outer side wall of the corresponding first connecting block and second connecting block, respectively.

[0018] By adopting the above technical solution, two limiting sleeves, together with the series columns, connect and fix the connecting ring to the connecting frame.

[0019] Preferably, the connecting ring is installed on the outer side wall of the first flexible shell and the second flexible shell, and a connecting cover is installed at one end of the connecting ring, and an elastic ring is installed at the other end of the connecting cover.

[0020] By adopting the above technical solution, the connecting cover is equipped with an elastic ring to seal the connection between the first flexible shell and the second flexible shell and the air conditioning duct body, which helps to protect the air conditioning duct body.

[0021] An air conditioning duct, applied to the aforementioned insulation structure, includes an air conditioning duct body that is installed through the interior of a first flexible shell and a second flexible shell. Both ends of the air conditioning duct body are equipped with connectors. Flange connecting rings are installed on the outer walls of the connectors. One side of the flange connecting ring abuts against one side of a silicone contact layer. A connecting sleeve is installed on the side of the silicone contact layer away from the flange connecting ring, and the inner wall of the connecting sleeve is threadedly connected to the outer wall of the air conditioning duct body.

[0022] By adopting the above technical solution, the occurrence of bolt loosening is reduced by using a silicone contact layer to abut against the outer wall of one side of the flange connecting ring.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The first and second flexible shells are used to cover the outside of the air conditioning duct body.

[0034] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0035] This application discloses an insulation structure and an air conditioning duct.

[0036] Reference Figure 1 , Figure 2 A thermal insulation structure includes a first flexible shell 1, one end of which abuts against one end of a second flexible shell 2. Both the first flexible shell 1 and the second flexible shell 2 are semi-circular arc-shaped structures. Both the first flexible shell 1 and the second flexible shell 2 are made of plastic material. The inner sidewalls of the first flexible shell 1 and the second flexible shell 2 are fixedly connected with thermal insulation cotton 3, which is also semi-circular arc-shaped. Flexible sleeves 4 are fixedly connected through the sidewalls of the thermal insulation cotton 3 at equal intervals. Guide steel wires 5 are fixedly connected inside the flexible sleeves 4. Inflatable wrapping balloons 6 are fixedly connected to the outer sidewalls of the thermal insulation cotton 3. Silicone anti-slip pads 7 are fixedly connected to the outer sidewalls of the wrapping balloons 6 away from the thermal insulation cotton 3.

[0037] The first flexible shell 1 and the second flexible shell 2 are set to cover the outside of the air conditioning duct body 22, and the air conditioning duct body 22 is insulated and protected by the heat insulation cotton 3, which effectively avoids the phenomenon of excessive temperature loss of the air conditioning duct body 22. At the same time, the wrapping balloon 6 and the silicone anti-slip pad 7 are wrapped around the outside of the air conditioning duct body 22, which further reduces temperature loss and can also effectively protect the air conditioning duct body 22. The wrapping balloon 6 and the guide steel wire 5 can make the air conditioning duct body 22 have a certain toughness, improve its performance, and extend the service life of the air conditioning duct body 22.

[0038] Reference Figure 1 , Figure 3 , Figure 4The outer walls of the first flexible shell 1 and the second flexible shell 2 are tightly fitted to the inner walls of the corresponding connecting frame 8. Both ends of the connecting frame 8 are fixedly connected to connecting blocks 9, and the side walls of the connecting blocks 9 are fixedly connected to limiting blocks 10. The top of the limiting blocks 10 abuts against the bottom of the mounting sleeve 14. Flexible sheets 13 are symmetrically fixedly connected to the inner walls of both sides of the mounting sleeve 14. The outer walls of the flexible sheets 13 are fixedly connected to second abutting protrusions 12 with a semi-cylindrical structure at equal intervals. The outer walls of the second abutting protrusions 12 abut against the outer walls of the first abutting protrusions 11 with a semi-cylindrical structure. The first abutting protrusions 11 are fixedly connected to the side walls of the connecting blocks 9 at equal intervals.

[0039] By cooperating with the two connecting brackets 8, the first flexible shell 1 and the second flexible shell 2 are limited, thereby wrapping the first flexible shell 1 and the second flexible shell 2 around the outside of the air conditioning duct body 22. At the same time, the two connecting brackets 8 are connected and fixed by fitting the mounting sleeve 14 on the outside of the two abutting connecting blocks 9, so that one end of the mounting sleeve 14 abuts against one end of the limiting block 10, and the outer wall of the first abutting protrusion 11 abuts against the outer wall of the second abutting protrusion 12, thereby limiting the mounting sleeve 14. By using this method to limit and fix the connecting brackets 8, it is easier to quickly disassemble the connecting brackets 8 during later maintenance, thus improving the practicality and convenience of the device.

[0040] Reference Figure 1 , Figure 3 , Figure 4 One end of the connecting frame 8 is provided with a connecting ring 19 that fits against the outer wall of the first flexible shell 1 and the second flexible shell 2. The outer walls of both sides of the connecting ring 19 are fixedly connected with second connecting blocks 17, and one end of the second connecting block 17 abuts against the first connecting block 15. The first connecting block 15 is fixedly connected to the side wall of the connecting frame 8. The interiors of the first connecting block 15 and the second connecting block 17 are both fixedly connected with a series post 16, and the outer wall of the series post 16 symmetrically abuts against the limiting sleeve 18. One end of the limiting sleeve 18 abuts against the outer wall of the corresponding first connecting block 15 or second connecting block 17. The end of the connecting ring 19 away from the connecting frame 8 is fixedly connected with a connecting cover 20, and the other end of the connecting cover 20 is fixedly connected to one end of the elastic ring 21.

[0041] The elastic ring 21 is designed to wrap around the outer wall of the air conditioning duct body 22, thereby sealing the connection with the connecting cover 20. This reduces the entry of cold air and liquid into the interior of the first flexible shell 1 and the second flexible shell 2, thus protecting the internal components of the first flexible shell 1 and the second flexible shell 2. When maintenance of the air conditioning duct body 22 is required, the connecting ring 19 can be quickly separated from the connecting frame 8, making maintenance easier. The connecting ring 19 is aligned with the second connecting block 17 fixed to the side wall of the connecting frame 8 by the first connecting block 15 installed on both sides, and then passes through the series column 16. The outer wall of the series column 16 is then limited by the limiting sleeve 18, thus completing the connection and fixation between the connecting ring 19 and the connecting frame 8.

[0042] Reference Figure 5 An air conditioning duct includes an air conditioning duct body 22 that is fixedly connected inside a first flexible shell 1 and a second flexible shell 2. The outer wall of the air conditioning duct body 22 is tightly fitted to the outer wall of a silicone anti-slip pad 7. Both ends of the air conditioning duct body 22 are fixedly connected to a plug 23 for connecting and fixing to a corresponding connection port. The outer wall of the plug 23 is fixedly connected to a flange connecting ring 24. Both ends of the outer wall of the air conditioning duct body 22 are threaded. Both ends of the outer wall of the air conditioning duct body 22 are threaded with a connecting sleeve 26. One end of the connecting sleeve 26 is fixedly connected to one end of a silicone contact layer 25.

[0043] The air conditioning duct body 22 is connected to the connection port of the air conditioning system through the connector 23, and the bolts are installed through the flange connecting ring 24 to limit and fix the connector 23. After the connector 23 is connected to the connection port of the air conditioning system, the connecting sleeve 26 is rotated to drive the silicone contact layer 25 to move towards the connector 23, further generating a contact force on the connector 23 and contacting the flange connecting ring 24, thereby contacting the flange connecting ring 24 and the bolts, protecting the bolts, reducing the occurrence of loosening factors, and improving the connection stability with the connection port of the air conditioning system.

[0044] The implementation principle of the insulation structure and air conditioning duct of this application embodiment is as follows: First, the air conditioning duct body 22 is connected to the connection port of the air conditioning system with the plug connector 23, and the plug connector 23 is fixed by the installation bolts through the flange connecting ring 24.

[0045] Secondly, rotate the connecting sleeve 26 to drive the silicone contact layer 25 to move toward the plug 23, further generating a contact force on the plug 23 and contacting the flange connecting ring 24;

[0046] Then, the elastic ring 21 is wrapped around the outer wall of the air conditioning duct body 22, and then the connection cover 20 is used to seal the connection, reducing the entry of cold air and liquid into the interior of the first flexible shell 1 and the second flexible shell 2.

[0047] Finally, by fitting the mounting sleeve 14 onto the outside of the two abutting connecting blocks 9, one end of the mounting sleeve 14 abuts against one end of the limiting block 10, and the outer wall of the first abutting protrusion 11 abuts against the outer wall of the second abutting protrusion 12, the mounting sleeve 14 is limited, thereby limiting the connecting frame 8 against the first flexible shell 1 and the second flexible shell 2. During use, the heat insulation cotton 3 provides heat insulation protection for the air conditioning duct body 22, effectively preventing excessive temperature loss from the air conditioning duct body 22. At the same time, the wrapping balloon 6, together with the silicone anti-slip pad 7, wraps around the outside of the air conditioning duct body 22, further reducing temperature loss and effectively protecting the air conditioning duct body 22. The wrapping balloon 6, together with the guide steel wire 5, gives the air conditioning duct body 22 a certain degree of toughness, improving its performance.

Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
