Technical Field

[0001] The utility model belongs to the technical field of central air-conditioning air ducts, in particular to a central air-conditioning air duct connection structure. Background Art

[0002] Central air conditioning ductwork is the piping system used to transport cold or hot air within a central air conditioning system. It's typically made of sheet metal (such as galvanized steel or aluminum alloy) and designed in various shapes and sizes depending on the scale and layout of the air conditioning system. Connectors connect the ductwork to form a complete network, transporting the hot and cold air generated by the air conditioning equipment to each room.

[0003] Existing central air conditioning duct connection structures often use flange connections, clamp connections, and welding connections. Although these connection methods can also achieve a fixed effect, their installation steps are cumbersome and inefficient, resulting in unsatisfactory performance. To address this issue, we provide a central air conditioning duct connection structure to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Example 1

[0028] See also Figure 1-5 The utility model is a central air-conditioning duct connection structure, including an air duct body 1, one side of the air duct body 1 is fixedly connected to a first connecting plate 2, and the other side of the air duct body 1 is fixedly connected to a second connecting plate 3; a limiting component is arranged inside the first connecting plate 2, and the limiting component includes a receiving groove 4, the receiving groove 4 is opened on both sides of the interior of the first connecting plate 2, one side of the receiving groove 4 is fixedly connected to a spring 5, the other end of the spring 5 is fixedly connected to a movable plate 6, the top and bottom of one side of the movable plate 6 are fixedly connected to a clamping block 7, one side of the second connecting plate 3 is fixedly connected to a clamping plate 8, and a clamping hole 9 is opened inside the clamping plate 8; a sealing groove 10 is opened inside the first connecting plate 2 and the second connecting plate 3, and a sealing ring 11 is arranged inside the sealing groove 10, and the sealing ring 11 is used to improve the sealing of the connection.

[0029] Specifically: The utility model only displays the structure of one group of central air-conditioning ducts. Other central air-conditioning ducts that need to be connected also have the same structure. Through the setting of the storage groove 4, the internal structure can be conveniently stored and protected. The clamping block 7 and the clamping hole 9 are adapted to each other to ensure stability during clamping. Through the opening of the sealing groove 10, the sealing ring 11 can be easily installed. Through the setting of the sealing ring 11, the sealing effect of the connection between the two groups of central air-conditioning ducts can be improved to avoid air leakage.

[0030] Example 2

[0031] See also Figure 1-5 On the basis of embodiment 1, load-bearing angle brackets 12 are provided on both sides of the bottom of the air duct body 1, and the load-bearing angle brackets 12 are internally threadedly connected to a hanger 13, and the top of the hanger 13 is fixedly connected to a fixing seat 14, and a fixing hole 15 is opened inside the fixing seat 14. One side of the clamping plate 8 is designed as an arc, and the clamping hole 9 and the clamping block 7 coincide with each other. A pull rod 16 is fixedly connected to one side of the movable plate 6, and the free end of the pull rod 16 extends to the outside of the receiving slot 4 and is fixedly connected to the pull block 17. An insertion groove 18 is opened on one side of the first connecting plate 2, and the insertion groove 18 coincides with the clamping plate 8. There are four clamping plates 8, two of which are arranged horizontally and two are arranged longitudinally. The movable plate 6 is slidably connected to the inner wall of the receiving slot 4, and the spring 5 is arranged in two groups, two in each group.

[0032] Specifically: There are two supporting angle brackets 12 to ensure the stability of the air duct body 1 during use. By setting the fixing seat 14 and the fixing hole 15, the hanging rod 13 can be installed in the required position. By setting the supporting angle bracket 12, the hanging rod 13, the fixing seat 14 and the fixing hole 15, the lifting work of the central air-conditioning air duct can be completed. By setting the pull rod 16 and the pull block 17, the movable plate 6 can be easily pulled to release the limiting work of the clamping block 7 on the clamping hole 9, which serves the purpose of facilitating subsequent disassembly and maintenance. The two groups of horizontally arranged clamping plates 8 do not have clamping holes inside. The reason for this design is that in order to facilitate the disassembly of the two groups of central air-conditioning air ducts, if limit components are set above and below the central air-conditioning air ducts, it will be inconvenient to disassemble. The horizontal clamping plates 8 in the utility model are longer, which can ensure the stability of the two groups of central air-conditioning air ducts during use.

[0033] The working principle of the present invention is as follows: the clamping plate 8 on one side of the second connecting plate 3 is inserted into the interior of the receiving groove 4 through the insertion groove 18. Since one side of the clamping plate 8 is designed as an arc, during the insertion process, the clamping block 7 will be pushed to move. Then, when the clamping plate 8 is fully inserted into the receiving groove 4, the spring 5 will automatically rebound, and the rebound force will push the movable plate 6 to move. The movable plate 6 drives the clamping block 7 to move, so that the clamping block 7 is inserted into the interior of the clamping hole 9, completing the limiting of the clamping plate 8. When the clamping plate 8 cannot move, the connection work of the two sets of central air-conditioning ducts can be completed. The present invention has a simple structure and high practicality, and is worthy of promotion.
