Description

Technical Field

[0001] This application relates to the field of air conditioning ducts, and in particular to a connection structure for air conditioning ducts. 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 that Chinese patent documents disclose a connection structure for air conditioning ducts and vents (Publication No.: CN221098937U), but it still has the following defects:

[0004] While the aforementioned connection structure for air conditioning ducts and vents allows for the installation of a plenum chamber between the air conditioning duct and the reserved opening, and the connection of the air conditioning duct and the reserved opening to a pair of side walls of the plenum chamber, achieving a flexible and tight connection between the air conditioning duct and the vent and preventing air leakage into the sealed ceiling, it still has drawbacks. When the air conditioning system needs to be maintained or repaired, if the duct needs to be disassembled, the bolt connection method requires unscrewing each bolt individually, which is quite troublesome. This is especially true when the bolts are rusted or have seized due to long-term use, making disassembly even more difficult. Utility Model Content

[0005] To address the issue that disassembling air ducts during maintenance or repair of air conditioning systems requires unscrewing each bolt individually, which is cumbersome, especially when bolts are rusted or seized due to long-term use, this application provides a connection structure for air conditioning ducts.

[0006] The connection structure for an air conditioning duct provided in this application adopts the following technical solution:

[0007] An air conditioning duct connection structure includes an air conditioning duct body, one end of which is fitted with a connecting sleeve, and the other end of which is connected to a flange connecting ring flange by connecting bolts. The flange connecting ring is fixed to the outer wall of one end of a second connector, and the second connector is fixedly connected to the inside of a sealing baffle. An abutment ball is installed on the outer wall of the second connector, and a silicone anti-slip pad is installed on the outer wall of the abutment ball.

[0008] By adopting the above technical solution, the second connector is inserted into the connection port of the indoor unit of the air conditioning system, and the contact balloon is used for limiting and sealing.

[0009] Preferably, one end of the connecting sleeve is provided with a first plug, and one end of the first plug is inserted into one end of the air conditioning duct body.

[0010] By adopting the above technical solution and using the first connector, the air conditioning duct body is connected to the air conditioning outdoor unit connection end in conjunction with the first connector.

[0011] Preferably, a silicone sealing ring is installed on the outer wall of one end of the connecting sleeve, and the silicone sealing ring is arranged in a circular structure.

[0012] By adopting the above technical solution and using the silicone sealing ring, the sealing effect at the connection point is improved.

[0013] Preferably, the bottom end of the connecting sleeve is equipped with a mounting base, and a plug-in cavity is provided through one side of the mounting base, and a plug-in block is inserted into one end of the plug-in cavity.

[0014] By adopting the above technical solution, the first connector can be connected to or separated from the outdoor unit of the air conditioner by the movement of the plug block inside the plug cavity.

[0015] Preferably, the front and rear ends of the plug block are each provided with a first limiting protrusion at equal intervals, and the outer sidewalls of the first limiting protrusions abut against the outer sidewalls of the second limiting protrusions.

[0016] By adopting the above technical solution, the outer walls of the first limiting protrusion abut against the outer walls of the second limiting protrusion, thereby limiting the insertion block.

[0017] Preferably, both the first limiting protrusion and the second limiting protrusion are semi-cylindrical structures, and the second limiting protrusion is installed at equal intervals at one end of the flexible sheet, and the flexible sheet is symmetrically installed inside the insertion cavity.

[0018] By adopting the above technical solution and using the flexible sheet, the flexible sheet can be deformed and reset during use, so that the outer wall of the first limiting protrusion abuts against the outer wall of the second limiting protrusion.

[0019] Preferably, one end of the plug-in block is equipped with a connecting block, and the connecting block is configured with a "U" shape. The other end of the connecting block is connected to one side of the mounting base, and the mounting base is equipped with several mounting bolts.

[0020] By adopting the above technical solution, the mounting base is fixed and limited by a number of mounting bolts, and then limited by the air conditioning duct body on the outside of the mounting base.

[0021] Preferably, one end of the air conditioning duct body near the flange connecting ring is inserted into one end of the second connector.

[0022] By adopting the above technical solution, the air conditioning duct body and the second connector are connected and fixed through the flange connecting ring.

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

[0024] 1. Using the second connector, the air duct is directly inserted into the connection port of the indoor unit in the air conditioning system, thereby completing the connection between the air duct body and the indoor unit in the air conditioning system. This method allows maintenance personnel to quickly separate the duct from the indoor unit when it is necessary to check the condition of the indoor unit or the duct, and greatly shortens the installation time. Especially in large projects where multiple indoor units and ducts need to be installed, it can significantly improve the overall installation progress, thus improving the practicality of the device.

[0025] 2. The air duct is connected to the outdoor unit of the air conditioning system via a first connector. After the mounting base with the first connector moves, it self-limits itself by abutting against the outer walls of the first and second limiting protrusions. This method allows for quick connection and disconnection of the air duct body from the outdoor unit during use. The self-limiting mechanism improves the stability of the air duct body, facilitates high-altitude operations, and provides a quick-release design for easy maintenance. Attached Figure Description

[0033] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0034] This application discloses a connection structure for an air conditioning duct.

[0035] Reference Figures 1-3 An air conditioning duct connection structure includes an air conditioning duct body 1, a connecting sleeve 2 with a circular structure fixedly connected to the outer wall of one end of the air conditioning duct body 1, and the end of the air conditioning duct body 1 near the connecting sleeve 2 is inserted into the interior of one end of a first plug 3. The other end of the first plug 3 is installed through the interior of the end near the connecting sleeve 2. A silicone sealing ring 4 with a circular structure is fixedly connected to the outer wall of the end of the connecting sleeve 2 near the first plug 3.

[0036] A connecting sleeve 2 is fixedly connected to the outer wall of the air conditioning duct body 1, so that the first plug 3 is plugged into the air conditioning duct body 1. During use, after the first plug 3 is connected to the outdoor unit of the air conditioning system, the outer wall of the outdoor unit connection port abuts against the silicone sealing ring 4, thereby improving the sealing of the connection.

[0037] Reference Figures 1-3 The bottom outer wall of the connecting sleeve 2 is fixedly connected to the mounting base 5, and the mounting base 5 has a through-hole cavity 6 on one side below. The insertion block 7 is inserted through the cavity 6, and the front and rear ends of the insertion block 7 are fixedly connected with a first limiting protrusion 8 with a semi-cylindrical structure at equal intervals. The outer wall of the first limiting protrusion 8 abuts against the outer wall of the second limiting protrusion 9, and the second limiting protrusion 9 is fixedly connected to the outer wall of one end of the flexible sheet 10 at equal intervals. The flexible sheet 10 is symmetrically fixedly connected to the inside of the insertion cavity 6, and one end of the insertion block 7 is fixedly connected to the mounting base 12 through the connecting block 11 with a "U" shaped structure.

[0038] The first connector 3 is connected to the outdoor unit connection port of the air conditioning system, thereby enabling air conditioning duct body 1 to transport air between the outdoor unit and the indoor unit. During use, the mounting base 12 is installed in the area compatible with the outdoor unit using bolts and other fasteners, and the connected plug block 7 is inserted into the plug cavity 6, thereby connecting the mounting base 12 to one end of the air conditioning duct body 1. The mounting seat 5 moves on the outer wall of the plug block 7, thereby completing the connection and disconnection between the first connector 3 and the outdoor unit connection port. After the mounting seat 5 moves, it self-limits by abutting the outer wall of the first limiting protrusion 8 against the outer wall of the second limiting protrusion 9. In this way, the air conditioning duct body 1 can be quickly connected and disconnected from the outdoor unit connection port during use, and the self-limiting mechanism further improves the stability of the air conditioning duct body 1.

[0039] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The end of the air conditioning duct body 1 away from the connecting sleeve 2 is fixedly connected to the flange connecting ring 13 by connecting bolts, and the end of the air conditioning duct body 1 near the flange connecting ring 13 is inserted into the interior of one end of the second connector 15. The flange connecting ring 13 is fixedly connected to the outer wall of the second connector 15, and a sealing baffle 14 with a circular structure is fixedly connected to the outer wall of the second connector 15. An inflatable abutment balloon 16 with an inflation structure is fixedly connected to the outer wall of the second connector 15, and a silicone anti-slip pad 17 is fixedly connected to the outer wall of the abutment balloon 16.

[0040] When one end of the air conditioning duct body 1 is connected to the indoor unit of the air conditioning system, the first end of the air conditioning duct body 1 is first connected and fixed to the end of the second connector 15 with the flange connecting ring 13 installed by bolts. The second connector 15 is directly inserted into the connection port of the indoor unit of the air conditioning system. Then, the contact ball 16 contacts the inner wall of the connection port, which not only completes the limiting operation, but also works with the sealing baffle 14 to seal it. At the same time, the contact ball 16 further improves the adhesion to the inner wall of the connection port through the silicone anti-slip pad 17 during the insertion process. In this way, it is easy to disassemble and assemble the indoor unit of the air conditioning system, and it is easy to perform maintenance work on the indoor unit of the air conditioning system.

[0041] The implementation principle of the connection structure of an air conditioning duct in this application embodiment is as follows: First, one end of the air conditioning duct body 1 is connected and fixed to the end of the second plug 15 with the flange connecting ring 13 installed by bolts, and the connecting sleeve 2 is fixedly connected to the outer wall of the air conditioning duct body 1, so that the first plug 3 and the air conditioning duct body 1 are plugged and connected.

[0042] Secondly, the mounting base 12 is installed to the area of ​​the outdoor unit of the air conditioning system using bolts and other fasteners;

[0043] Then, by pushing the mounting base 5, the mounting base 5 moves on the outer wall of the plug block 7, thereby completing the connection between the first plug 3 and the connection port of the outdoor unit of the air conditioning system. At the same time, after the mounting base 5 moves, it is self-limited by the outer wall of the first limiting protrusion 8 and the outer wall of the second limiting protrusion 9.

[0044] Finally, when one end of the air conditioning duct body 1 is connected to the indoor unit of the air conditioning system, the first end of the air conditioning duct body 1 is connected and fixed to the end of the second connector 15 with the flange connecting ring 13 installed by bolts. The second connector 15 is directly inserted into the connection port of the indoor unit of the air conditioning system. Then, the contact ball 16 contacts the inner wall of the connection port to complete the limiting operation. At the same time, the sealing baffle 14 is used to seal the connection. This completes the connection structure of the air conditioning duct.

[0045] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. 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.
