Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, specifically to a fan coil unit hoisting port structure, which simplifies the unit hoisting process and improves structural strength. Background Technology

[0002] Fan coil units are terminal equipment in central air conditioning systems, mainly used to regulate indoor air temperature and humidity, and are widely used in commercial buildings, office buildings, and residences. They typically consist of a fan, heat exchange coils, and return air boxes, and are fixed to the ceiling by suspension to save space and ensure uniform airflow distribution.

[0003] Traditional fan coil unit mounting ports typically use a slotted hole design, requiring complete removal of nuts and insertion of the lifting rod during installation. This process is cumbersome, requires multiple people, and is inefficient. Furthermore, the need for repeated adjustments to the unit's position during hoisting can easily lead to bolt loosening or side plate deformation, affecting installation stability. Therefore, there is an urgent need for a simple, easy-to-install, and robust mounting port structure to improve construction efficiency and reduce the risk of equipment damage. Utility Model Content

[0004] The purpose of this utility model is to provide a fan coil unit hoisting port structure to solve the problems of low efficiency, easy deformation and bolt loosening in traditional hoisting methods.

[0005] The technical solution provided by this utility model is a fan coil unit hoisting port structure, including a hoisting frame. The inner two sides of the hoisting frame are a fan unit and a return air box, respectively. The fan unit has a first side plate at both ends, and a first upper panel is vertically connected to the top of the fan unit. The return air box has a second side plate at both ends, and a second upper panel is located above the return air box. The first upper panel has a first hoisting port on both sides above it. The first hoisting port has a U-shaped structure, and a baffle plate is located on the outer side of the bottom of the first hoisting port. The second upper panel has a second hoisting port above it. The second hoisting port has a U-shaped structure.

[0006] As a preferred technical solution of this utility model, the first side plate and the second side plate are both recessed groove structures at both ends of the fan unit and the return air box, and corresponding vertical extension sides are provided at the edges of the groove structures.

[0007] As a preferred technical solution of this utility model, the extended sides of the first side plate and the second side plate are provided with corresponding openings at the first hoisting port and the second hoisting port, and the outer side of the opening is provided with reinforcing ribs that are equidistant from the outer shape of the opening.

[0008] As a preferred embodiment of this utility model, the reinforcing rib is a stamped structure and is located below the extended side, thus limiting the nut used for hoisting.

[0009] As a preferred embodiment of this utility model, both the first lifting port and the second lifting port are located at the edges of the first upper panel and the second upper panel.

[0010] As a preferred technical solution of this utility model, the blocking plate is a symmetrically arranged L-shaped plate structure, and the blocking plates on both sides are located on both sides of the first hoisting opening to limit the nuts used for hoisting on the inner side.

[0011] The advantages of this utility model compared with the prior art are as follows:

[0012] 1. This hoisting structure uses a U-shaped hoisting port design to allow the hoisting rod to be directly inserted without completely disassembling the nuts, allowing for operation by a single person and high installation efficiency;

[0013] 2. This hoisting structure uses reinforcing ribs and retaining plates to limit the nuts, preventing bolts from loosening or falling off, enhancing the overall structural strength, reducing the risk of deformation during handling or installation, and improving hoisting stability.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within 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.

[0020] Example 1:

[0021] As per the instruction manual Figure 1-2 As shown, a fan coil unit hoisting port structure includes a hoisting frame 1, with a fan unit 2 and a return air box 3 on the inner two sides of the hoisting frame 1, respectively.

[0022] The fan unit 2 has a first side plate 4 at both ends, and the first side plate 4 is vertically connected to the first upper panel 5 above the fan unit 2; the return air box 3 has a second side plate 6 at both ends, and the second side plate 6 is provided with a second upper panel 7 above the return air box 3. The first side plate 4 and the second side plate 6 at both ends of the fan unit 2 and the return air box 3 are both recessed groove structures, and corresponding vertical extension edges 11 are provided at the edges of the groove structures.

[0023] The upper sides of the first upper panel 5 are provided with first lifting ports 8. The first lifting ports 8 are U-shaped and located at the edge of the first upper panel 5. The extended sides 11 of the first side panel 4 and the second side panel 6 are provided with corresponding openings 12 at the first lifting ports 8 and the second lifting ports 10. The outer side of the opening 12 is provided with reinforcing ribs 13 that are equidistant from the outer shape of the opening 12. The reinforcing ribs 13 are stamped and are located below the extended sides 11 to limit the nuts used for lifting. The bottom outer side of the first lifting port 8 is provided with a blocking plate 9. The blocking plate 9 is a symmetrically arranged L-shaped plate structure and is fixed below the extended side 11 of the first side panel 4 by welding. The two blocking plates 9 are located on both sides of the first lifting port 8 to limit the nuts used for lifting on the inner side.

[0024] The second upper panel 7 is provided with a second lifting port 10 above it. The second lifting port 10 has a U-shaped structure and is located at the edge of the second upper panel 7. At the same time, a corresponding blocking piece 9 can also be provided at the second lifting port 10.

[0025] In a specific implementation of this utility model, the lifting rod slides laterally into the first lifting port 8 and the second lifting port 10 of the U-shaped structure, and then is pulled upwards, so that the nut at the bottom of the lifting rod is limited by the blocking plate 9 and the reinforcing rib 13 to prevent loosening; the channel-shaped side plate and the reinforcing rib 13 structure enhance the overall rigidity, reduce the risk of deformation, and improve the stability of the lifting.
