When damage occurs, the fan needs to be disassembled, removed and replaced. However, the internal space of the refrigerator is small, making operation inconvenient and not conducive to the use of tools to install and disassemble the fan.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A refrigerator refrigeration air duct assembly includes an air duct panel with a fan slot. Two opposing mounting mechanisms are disposed on one side of the air duct panel, and a fan can be installed between the mounting mechanisms. A placement block for receiving the fan is fixedly connected to one side of the air duct panel. Each mounting mechanism includes a mounting block fixedly connected to the air duct panel. A sliding groove is formed on the side of the mounting blocks that are close to each other. A movable groove is formed inside the mounting block.

A retaining strip one is rotatably connected inside placement groove one, and a retaining strip two is rotatably connected inside placement groove two. One end of retaining strip one and retaining strip two extends into the movable groove, and the other end of retaining strip one and retaining strip two extends out of placement groove one and the sliding groove, respectively.
[0007] Preferably, a connecting rod is provided between the first card strip and the second card strip, with both ends rotatably connected to the first card strip and the second card strip respectively.
[0008] Preferably, the bottom of the mounting block has a through groove communicating with the movable groove, and the bottom of the second locking strip is rotatably connected to a second connecting rod inside the movable groove, and the bottom of the second connecting rod is fixedly connected to a counterweight block.
[0009] Preferably, two slots are provided on both sides of the fan, and the slots can be adapted to the rotation paths of the first and second slots. The ends of the first and second slots that extend out of the slide groove can extend into the slots.
[0010] Preferably, each of the slide grooves is slidably connected to a slider, the bottom of the slider abutting against the top of the first locking strip, the top of the slider extending out of the slide groove and fixedly connected to the same pressing block, and the pressing block is equipped with a quick-release mechanism for easy removal of the fan.
[0011] Preferably, the quick-release mechanism includes a movable plate rotatably connected to the pressing block, an elastic telescopic block is fixedly connected to one side of the pressing block, the end of the elastic telescopic block away from the pressing block abuts against one side of the movable plate, and a plurality of toothed blocks are fixedly connected to the top of the fan.
[0012] Compared with the prior art, this utility model has at least the following beneficial effects:
[0013] In the above solution, by setting up an installation mechanism, when the fan needs to be installed, the pressing block is pressed down, causing the slider at the bottom of the pressing block to slide downwards inside the slide groove. This causes the locking strip 1, which is in contact with the bottom of the slider, to rotate downwards. The locking strip 1 will gradually rotate into the placement slot 1. During the rotation of the locking strip 1, one end of the locking strip 1 will rotate upwards, causing one end of the locking strip 2 to rotate upwards as well. The end of the locking strip 2 extending out of the slide groove will gradually rotate downwards into the placement slot 2. At the same time, the connecting rod 2 will be affected by the rotation of the locking strip 2, thus causing the counterweight to move together. The connecting rod 2 will slide inside the through groove. When both locking strips 1 and 2 on the two mounting blocks have rotated into the placement slots 1 and 2, the fan can be placed on the placement block. Place the fan between the mounting blocks and align it with the fan slot. Then, lift the pressing block upwards to reset it. The second locking strip will rotate downwards at one end in the movable slot due to the influence of the counterweight block via the connecting rod second, and simultaneously rotate the first locking strip to reset via the connecting rod first. When the top of the second locking strip touches the inner wall of the top of the placement slot second, stop rotating to complete the reset. The first and second locking strips will extend into the slot on the side of the fan as they rotate, fixing the fan in place and completing the installation. The advantage of this method is that the fan installation can be completed simply by pressing the pressing block downwards, placing the fan on the placement block, and then resetting the pressing block. The operation is simple and quick, requiring no other tools. Even in a small operating space, it can be completed quickly, making it convenient for operators.
[0014] By setting up a quick-release mechanism, when the fan needs to be removed due to damage, pressing down on the pressing block causes the slider to rotate the first locking strip into the first placement slot. At the same time, the connecting rod will rotate the second locking strip into the second placement slot, allowing the first and second locking strips to rotate out of the slots on the side of the fan. When one end of the movable plate abuts against the toothed block, both the first and second locking strips rotate into the first and second placement slots. At this time, pressing the movable plate will cause it to press against the elastic telescopic block. The end of the movable plate away from the elastic telescopic block will move the fan away from the air duct panel through the toothed block. The advantage of this is that the fan can be quickly moved out from between the mounting blocks when it needs to be removed, making it convenient for staff to pick up and remove the fan.

A fan slot 12 is provided on the air duct panel 1. Two opposing mounting mechanisms 3 are provided on one side of the air duct panel 1, and a fan 2 can be installed between the mounting mechanisms 3. A placement block 9 for receiving the fan 2 is fixedly connected to one side of the air duct panel 1. The mounting mechanism 3 includes a mounting block 31 fixedly connected to the air duct panel 1. A sliding groove 32 is provided on the side of the mounting blocks 31 that is close to each other. The interior of the mounting block 31 is... A movable groove 33 is provided, and a placement groove 1 34 and a placement groove 2 35 are formed on one inner wall of the movable groove 33. Both placement groove 1 34 and placement groove 2 35 are connected to the sliding groove 32. A retaining strip 1 36 is rotatably connected inside the placement groove 1 34, and a retaining strip 2 37 is rotatably connected inside the placement groove 2 35. One end of both retaining strip 1 36 and retaining strip 2 37 extends into the interior of the movable groove 33, and the other end of both retaining strip 1 36 and retaining strip 2 37 extends out of the placement groove 1 34 and the sliding groove 32. A connecting rod 38 is provided at both ends, which are rotatably connected to the first locking strip 36 and the second locking strip 37 respectively. A through groove 39 communicating with the movable groove 33 is opened at the bottom of the mounting block 31. A connecting rod 10 is rotatably connected to the bottom of the second locking strip 37 inside the movable groove 33. A counterweight block 11 is fixedly connected to the bottom of the connecting rod 10. The connecting rod 10... A counterweight 11 is fixedly connected to the bottom. Two slots 7 are opened on both sides of the fan 2. The slots 7 can be adapted to the rotation path of the first slot 36 and the second slot 37. One end of the first slot 36 and the second slot 37 extending out of the slide groove 32 can extend into the slot 7. A slider 6 is slidably connected inside the slide groove 32. The bottom of the slider 6 abuts against the top of the first slot 36. The top of the slider 6 extends out of the slide groove 32 and is fixedly connected to the same pressing block 4. A quick-release mechanism 5 for easy removal of the fan 2 is installed on the pressing block 4.
[0025] By setting the installation mechanism 3, when the fan 2 needs to be installed, the pressing block 4 is pressed down, causing the slider 6 at the bottom of the pressing block 4 to slide downward inside the slide groove 32. This causes the locking strip 36, which is in contact with the bottom of the slider 6, to rotate downward. The locking strip 36 will gradually rotate into the placement groove 34. During the rotation of the locking strip 36, one end of the locking strip 36 in the movable groove 33 will rotate upward, causing one end of the locking strip 37 to rotate upward together through the connecting rod 38. The end of the locking strip 37 extending out of the slide groove 32 will gradually rotate downward into the placement groove 35. At the same time, the connecting rod 10 will be affected by the rotating locking strip 37, thus causing the counterweight 11 to move together. The connecting rod 10 will slide inside the through groove 39. When the locking strips 36 and 37 on both mounting blocks 31 have rotated into the placement grooves 34 and 35, the fan 2 can be placed. On the placement block 9, align the fan 2 between the mounting blocks 31 and the fan slot 12. Then, lift the pressing block 4 upwards to reset it. The second locking strip 37 will rotate downwards to reset through the influence of the counterweight block 11 via the connecting rod 10. At the same time, the first locking strip 36 will rotate to reset through the connecting rod 38. When the top of the second locking strip 37 touches the top inner wall of the placement slot 35, the rotation stops, and the reset is completed. The first locking strip 36 and the second locking strip 37 will extend into the slot 7 on the side of the fan 2 as they rotate, fixing the fan 2 and completing the installation. The advantage of this method is that the installation of the fan 2 can be completed simply by pressing down the pressing block 4, placing the fan 2 on the placement block 9, and then resetting the pressing block 4. The operation is simple and quick, requiring no other tools. It can be completed quickly even in a small operating space, which is convenient for the operator.
[0026] like Figure 1 , Figure 3 and Figure 4As shown, the quick-release mechanism 5 includes a movable plate 51 rotatably connected to the pressing block 4. An elastic telescopic block 52 is fixedly connected to one side of the pressing block 4. The end of the elastic telescopic block 52 away from the pressing block 4 abuts against one side of the movable plate 51. Multiple toothed blocks 8 are fixedly connected to the top of the fan 2. By setting the quick-release mechanism 5, when the fan 2 is damaged and needs to be removed, the pressing block 4 is pressed down, causing the slider 6 to rotate the locking strip 36 into the placement slot 34. At the same time, the connecting rod 38 will drive the locking strip 37 to rotate into the placement slot 35, thereby allowing the locking strip 36 and the locking strip 37 to rotate into the placement slot 35. Strip 2 37 rotates out of the slot 7 on the side of the fan 2. When one end of the movable plate 51 abuts and engages with the toothed block 8, both the first locking strip 36 and the second locking strip 37 rotate into the placement slot 1 34 and the placement slot 2 35. At this time, press the movable plate 51 to squeeze the elastic telescopic block 52. The end of the movable plate 51 away from the elastic telescopic block 52 will drive the fan 2 to move away from the air duct panel 1 through the toothed block 8. The advantage of doing this is that when the fan 2 needs to be disassembled, the fan 2 can be quickly moved out from between the mounting blocks 31, which makes it convenient for the staff to take the fan 2 out.
[0027] The technical solution provided by this utility model, through the installation mechanism 3, allows the pressing block 4 to be pressed down when the fan 2 needs to be installed. This causes the slider 6 at the bottom of the pressing block 4 to slide downwards inside the slide groove 32, allowing the locking strip 36, which is in contact with the bottom of the slider 6, to rotate downwards. The locking strip 36 gradually rotates into the placement groove 34. During the rotation of the locking strip 36, one end of the locking strip 36 in the movable groove 33 rotates upwards, causing one end of the locking strip 37 to rotate upwards along with it via the connecting rod 38. The end of the locking strip 37 extending out of the slide groove 32 gradually rotates downwards into the placement groove 35. Simultaneously, the connecting rod 10 is affected by the rotating locking strip 37, thus causing the counterweight 11 to move together. The connecting rod 10 slides inside the through groove 39. When both locking strips 36 and 37 on the two mounting blocks 31 have rotated into the placement grooves 34 and 35, the fan 2 can be installed. Place the fan 2 on the placement block 9, aligning it with the fan slot 12 between the mounting blocks 31. Then, lift the pressing block 4 upwards to reset it. The second locking strip 37 will rotate downwards through the connecting rod 10, influenced by the counterweight 11, until it is reset. At the same time, the connecting rod 38 will drive the first locking strip 36 to rotate until it is reset. When the top of the second locking strip 37 touches the inner wall of the top of the placement slot 35, the rotation stops, completing the reset. The first locking strip 36 and the second locking strip 37 will extend into the slot 7 on the side of the fan 2 as they rotate, fixing the fan 2 and completing the installation. The advantage of this method is that the installation of the fan 2 can be completed simply by pressing down the pressing block 4, placing the fan 2 on the placement block 9, and then resetting the pressing block 4. The operation is simple and quick, requiring no other tools. It can be completed quickly even in a small operating space, making it convenient for operators.
[0028] By setting up a quick-release mechanism 5, when the fan 2 is damaged and needs to be removed, press down on the pressing block 4 to make the slider 6 drive the locking strip 36 to rotate into the placement slot 34. At the same time, the connecting rod 38 will drive the locking strip 37 to rotate into the placement slot 35, so that the locking strip 36 and the locking strip 37 can rotate out of the locking slot 7 on the side of the fan 2. When one end of the movable plate 51 abuts and engages with the toothed block 8, the locking strip 36 and the locking strip 37 will both rotate into the placement slot 34 and the placement slot 35. At this time, press the movable plate 51 to squeeze the elastic telescopic block 52. The end of the movable plate 51 away from the elastic telescopic block 52 will drive the fan 2 to move away from the air duct panel 1 through the toothed block 8. The advantage of this is that when the fan 2 needs to be removed, it can be quickly moved out from between the mounting blocks 31, which is convenient for the staff to take the fan 2 out.
