Description

Technical Field

[0001] This utility model relates to the technical field of cooling fan structure, specifically to a cooling fan structure for a gradient filter. Background Technology

[0002] In modern industrial and electronic equipment, cooling fans are key thermal management components, and their performance and reliability directly affect the operating efficiency and lifespan of the equipment. Gradient filters, as an advanced filtration structure, can adjust filtration performance in different dimensions to meet diverse heat dissipation needs.

[0003] However, when it is necessary to remove and replace the fan, the fan shield of the cooling fan is difficult to remove, requiring the fixing bolts to be unscrewed one by one, which makes the disassembly process cumbersome and reduces the disassembly speed. Therefore, a gradient filter cooling fan structure is proposed to overcome the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a cooling fan structure for a gradient filter. By rotating the turntable, the rotating rod is driven to rotate, thereby rotating through the first thread and the second thread. This causes the first moving plate to move on the first thread and the second moving plate to move on the second thread, thereby driving the first L-shaped block and the second L-shaped block to move and retract into the placement groove, releasing the fixing limit on the fixed plate, and disassembling the protective cover. This solves the problem that it is cumbersome to unscrew the fixing bolts one by one, which reduces the disassembly speed.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a cooling fan structure for a gradient filter, comprising a mounting plate, a fixing plate, and a rotating rod. The mounting plate has three mounting slots on one side, and a rectangular slot on one side of each mounting slot. Two insert blocks are respectively located at the upper and lower parts of one side of the rectangular slot, each insert block having a placement slot. Four sliding grooves are located on one side of the mounting slot. The rotating rod has a first thread at its upper part, on which a first movable plate is fitted. A first L-shaped block is located on one side of the first movable plate, and is positioned within the upper sliding groove and placement slot. The rotating rod has a second thread at its lower part, on which a second movable plate is fitted. A second L-shaped block is located on one side of the second movable plate, and is positioned within the lower sliding groove and placement slot. A protective cover is provided on the fixing plate, which has four insertion holes. The fixing plate is mounted on the insert blocks through these holes and is limited by vertical plates on the first and second L-shaped blocks.

[0007] Furthermore, a placement groove is provided at the top of the upper insertion block and a placement groove is provided at the bottom of the lower insertion block.

[0008] Furthermore, the four grooves correspond to the four placement slots respectively.

[0009] Furthermore, the rectangular groove is equipped with four support rods, and a driving component is provided between the support rods. A fan is provided at the output end of the driving component.

[0010] Furthermore, bearings are provided on both sides of the top and bottom of the mounting groove, and the two ends of the rotating rod are respectively set in the bearings at the top and bottom.

[0011] Furthermore, a turntable is provided at the top of the rotating rod.

[0012] Furthermore, the vertical plates on the first L-shaped block and the vertical plates on the second L-shaped block are oriented in opposite directions.

[0013] Furthermore, the thread directions between the first thread and the second thread are opposite.

[0014] This utility model has the following beneficial effects:

[0015] This invention uses a rotating turntable to drive a rotating rod to rotate, which in turn causes the first moving plate to move on the first thread and the second moving plate to move on the second thread. This causes the first L-shaped block and the second L-shaped block to move and retract into the placement groove, releasing the fixing limit on the fixed plate and allowing the protective cover to be disassembled. This solves the problem of having to unscrew the fixing bolts one by one, which makes the disassembly process cumbersome and reduces the disassembly speed.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] Please see Figure 1-4 This utility model provides a technical solution: a cooling fan structure for a gradient filter, including a mounting plate 1, a fixing plate 3, and a rotating rod 5. Three mounting slots 101 are provided on one side of the mounting plate 1, and a rectangular slot 102 is provided on one side of each mounting slot 101. Two insert blocks 6 are respectively provided at the upper and lower parts of one side of the rectangular slot 102. Placement slots 601 are provided on the insert blocks 6, with the upper insert block 6 having a placement slot 601 at its top and the lower insert block 6 having a placement slot 601 at its bottom. Four sliding grooves 104 are provided on one side of the mounting slots 101, corresponding to the four placement slots 601. Bearings 4 are provided on both sides of the top and bottom of the mounting slots 101. The two ends of the rotating rod 5 are respectively positioned in the bearings 4 at the top and bottom. A first thread 501 is provided on the upper part of the rotating rod 5, and a first moving plate 5 is fitted onto the first thread 501. 02. A first L-shaped block 504 is provided on one side of the first movable plate 502. The first L-shaped block 504 is disposed in the upper sliding groove 104 and the placement groove 601. A second thread 505 is provided at the lower part of the rotating rod 5. The thread directions between the first thread 501 and the second thread 505 are opposite. A second movable plate 506 is fitted on the second thread 505. A second L-shaped block 508 is provided on one side of the second movable plate 506. The vertical plate on the first L-shaped block 504 and the vertical plate on the second L-shaped block 508 are opposite. The second L-shaped block 508 is disposed in the lower sliding groove 104 and the placement groove 601. A turntable 509 is provided at the top of the rotating rod 5. A protective cover 301 is provided on the fixed plate 3. Four insertion holes 302 are provided on the fixed plate 3.

[0024] By rotating the turntable 509, the rotating rod 5 is driven to rotate, thereby rotating the first thread 501 and the second thread 505. This causes the first moving plate 502 to move on the first thread 501 and the second moving plate 506 to move on the second thread 505. This causes the first L-shaped block 504 and the second L-shaped block 508 to move and retract into the placement groove 601, releasing the fixing limit on the fixed plate 3 and disassembling the protective cover 301. This solves the problem of having to unscrew the fixing bolts one by one, which makes the disassembly process cumbersome and reduces the disassembly speed.
