Description

Technical Field

[0001] This utility model relates to the field of fan coil unit installation technology, specifically a fan coil unit connection structure. Background Technology

[0002] Fan coil units are one of the terminal devices in an air conditioning system. When water of different temperatures flows through the coil, it exchanges with the air outside the coil, thereby cooling, dehumidifying, or heating the air to regulate the indoor temperature. It consists of a housing, fan, heat exchanger, condensate pan, motor, and filter group. It is commonly used in central air conditioning systems.

[0003] Currently, when installing suspended fan coil units, four connecting rods are installed on the wall of the target area. Then, the bottom of the connecting rods is connected to the top of the fan coil unit in the housing with bolts and nuts, forming a four-corner suspension to complete the connection and installation. However, the current installation requires multiple workers to carry it to the upper part of the room, align the fan coil unit with the bottom of the connecting rods, and install it one by one. During this process, multiple workers need to support the fan coil unit at all times, which is very troublesome and labor-intensive. It also increases the difficulty of operation for the workers and requires multiple people to operate together. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide a fan coil unit connection structure.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: a fan coil unit connection structure, including connecting rods, four of which are vertically arranged in a rectangular distribution, a connecting plate at the bottom of the four connecting rods, a housing fixedly mounted on the lower surface of the connecting plate, a water receiving tray fixedly mounted on the bottom of the housing, an air outlet on the front of the housing, a stop block fixedly mounted on the connecting plate, a support plate sleeved on the connecting rod above the stop block, the support plate being U-shaped, the bottom of the support plate abutting against the lower surface of the water receiving tray, vertically mounted blocks fixedly mounted on the bottom side of the support plate facing the water receiving tray, a lead screw rotating between two adjacent blocks, the threads at both ends of the lead screw being opposite, a positioning plate movably mounted on the horizontal bottom end of the support plate, the bottom thread of the positioning plate being inserted into the end of the lead screw, and the upper end of the positioning plate abutting against the water receiving tray.

[0006] Preferably, the top of the support plate has a first mounting groove, and a positioning block is slidably provided on the upper surface of the top of the support plate. The positioning block has a second mounting groove that is the same as the first mounting groove and is arranged in a cross shape with it. The top of the support plate away from the connecting rod is fixedly provided with a mounting block. A moving block is slidably provided inside the mounting block, and a long rod is fixedly provided on the side wall of the moving block. The end of the long rod passes through the mounting block and is fixedly provided on the positioning block. A strong spring is fixedly connected to the interior of the moving block and the mounting block. Attractive magnetic blocks are respectively fixed between the two ends of the long rod on the opposite side of the positioning block and the mounting block. The attraction force of the magnetic blocks is greater than the tension force of the strong spring.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] 1. By placing the fan coil unit at the bottom of the support plate and using the rotating wheel to drive the screw to rotate, the positioning plate and the water receiving tray are brought into contact to complete the pre-installation and support. This eliminates the need for continuous manual lifting and greatly reduces the labor intensity of the staff.

[0009] 2. After the fan coil unit is finally fixed, the positioning block and the magnetic block on the mounting block can be attracted by pulling the pull block, so that the second mounting slot is disengaged from the connecting rod. Then, the support plate can be pulled to disengage the first mounting slot, so that the support plate can be easily disassembled, and the fan coil unit is in an independent and stable final connection state without affecting the normal operation of the equipment.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-4 As shown, this utility model provides a fan coil unit connection structure, including four vertically arranged rectangular connecting rods 13. A connecting plate 12 is provided at the bottom of each of the four connecting rods 13. A housing 1 is fixedly mounted on the lower surface of the connecting plate 12. A water collection tray 11 is fixedly mounted at the bottom of the housing 1. The front of the housing 1 is the air outlet, and the back of the housing 1 is connected to components such as a fan, motor, and heat exchanger. The specific connection method is a conventional connection and will not be described in detail here. A stop block 31 is fixedly mounted on the connecting plate 12. A support plate 2 is fitted on the connecting rod 13 above the stop block 31. The support plate 2 is U-shaped. The bottom of the support plate 2 abuts against the lower surface of the water receiving tray 11. Vertical blocks 21 are fixed on the bottom side of the support plate 2 facing the water receiving tray 11. A screw rod 22 is rotatably mounted between two adjacent blocks 21. The two ends of the screw rod 22 have opposite threads. A positioning plate 23 is movably fitted on the bottom horizontal end of the support plate 2. The bottom thread of the positioning plate 23 is inserted into the end of the screw rod 22. The upper end of the positioning plate 23 abuts against the water receiving tray 11.

[0018] One end of the lead screw 22 passes through the vertical block 21 and is fixedly equipped with a rotating wheel 24 with anti-slip strips on its surface. The rotating wheel 24 is designed to facilitate the operator to quickly rotate the lead screw 22 and improve the ease of operation.

[0019] A shock absorber 14 is fixedly connected to the top of the connecting rod 13 by bolts. The top of the shock absorber 14 is fixedly connected to the wall by fixing bolts. The shock absorber 14 is mainly used to reduce vibration during the subsequent hoisting of the fan coil unit.

[0020] The top of the support plate 2 has a first mounting groove 3. A positioning block 32 is slidably mounted on the upper surface of the top of the support plate 2. The positioning block 32 has a second mounting groove 33 that is the same as the first mounting groove 3 and is arranged in a cross shape with it. The top of the support plate 2 away from the connecting rod 13 is fixedly mounted on a mounting block 34. A moving block 36 is slidably mounted inside the mounting block 34, and a long rod 35 is fixedly mounted on the side wall of the moving block 36. The end of the long rod 35 passes through the mounting block 34 and is fixedly mounted on the positioning block 32. The moving block 36 and the interior of the mounting block 34 are connected. A strong spring 37 is provided for the common fixed connection. The strong spring 37 pulls the moving block 36 to drive the long rod 35 to move toward the position of the connecting rod 13. At this time, the positioning block 32 fixed at the end of the long rod 35 is inserted into the connecting rod 13 through the second mounting groove 33. At this time, the connecting rod 13 will be stably connected to the support plate 2 under the limitation of the first mounting groove 3 and the second mounting groove 33 which are arranged in a cross shape. It will not shake at will, and it is also convenient to provide stable support for the water receiving tray 11 during the subsequent overall installation.

[0021] On the opposite side of the positioning block 32 and mounting block 34, magnetic blocks 38 are fixedly installed between the two ends of the long rod 35. The attraction force of the magnetic blocks 38 is greater than the tension of the strong spring 37. Through the magnetic blocks 38, the positioning block 32 is ultimately held in place. Figure 4 As shown, the positioning block 32 is disengaged from the connecting rod 13, thereby facilitating the overall disengagement of the support plate 2 from the connecting rod 13, so that the fan coil unit is in the final connected state; the upper surface of the positioning block 32 is fixedly provided with a protruding pull block 39, which facilitates the operator to pull the positioning block 32 to move it, so that it squeezes and pulls the spring and causes the magnetic blocks 38 to attract each other.

[0022] Working principle: In use, the top of the connecting rod 13 is pre-installed in the working area using fixing bolts. Then, the operator supports the fan coil unit so that the water receiving tray 11 at its bottom abuts against the bottom of the support plate 2 on the connecting rod 13. Figure 1 , 2 As shown, the fan coil unit is pre-installed at the bottom of the four connecting rods 13. Then, the operator only needs to rotate the wheel 24 to drive the screw 22 to rotate. The positioning plates 23 with threads at both ends of the screw 22 will move towards each other and abut against the water receiving tray 11. The water receiving tray 11 and the entire fan coil unit only need to be limited to avoid random sliding during installation, which would affect the installation efficiency. Subsequently, the operator can connect the bottom of the connecting rod 13 to the connecting plate 12 on the fan coil unit one by one with bolts. Through the above operation, the operator only needs to place the fan coil unit at the bottom of the support plate 2. At this time, the fan coil unit can be pre-installed and supported. The operator does not need to hold the fan coil unit all the time, which greatly reduces the labor intensity of the operator and improves the convenience of the operator's installation.

[0023] After the connecting rods 13 are fixedly connected to the top corners of the connecting plate 12 on the fan coil unit, the workers pull the positioning block 32 towards the mounting block 34 by pulling the pull block 39. At this time, the magnetic block 38 on the mounting block 34 and the positioning block 32 will attract each other. At this time, the second mounting groove 33 will disengage from the connecting rod 13. Then, the workers pull the support plate 2 one by one to disengage the first mounting groove 3 to complete the disassembly of the support plate 2, so that the fan coil unit is in the final connected state.

[0024] All standard parts used in this invention can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods of each part all adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connections adopt conventional connection methods in the prior art, which will not be described in detail here.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
