Then move the second rectangular plate 26 up into the inner cavity of the first rectangular plate 24, and at the same time drive the two oval grooves 30 to make the first rectangular plate 24 rotate, and make the sector block 31 clamped in the internal of the sector groove. Then first rotate and then pull the two first rectangular plates 24 to easily remove the installation part 2 from the fan main body 1 without the help of other tools, with quick operation, time and labor saving, and improved efficiency.
[0032] Embodiment 2. Please refer to Figures 1 to 12 , on the basis of Embodiment 1, the first installation groove 5 includes two internally interconnected first slots and an inner sliding groove. The clamping plate 8 is fixedly connected to one end of the inner wall of the first arc-shaped groove. The clamping member 9 is slidably connected to both the inside of the first slot and the first arc-shaped groove. The cross-sectional area of the first slot is equal to that of the clamping member 9. A stabilizing groove 10 is formed at one end of the clamping member 9, and a fastening groove 11 is formed on one outer wall of the clamping member 9. The inside of the stabilizing groove 10 and the fastening groove 11 communicate with each other. One end of the clamping plate 8 and both ends of the stabilizing groove 10 are chamfered. An accommodating groove 6 is formed on one side of the inner wall of the first arc-shaped groove. A through hole 7 is opened at one end of the inner wall of the accommodating groove 6. Auxiliary grooves are formed on both inner walls of the accommodating groove 6. An auxiliary plate 13 is slidably connected to the inner wall of the auxiliary groove. A fastener 12 is fixedly connected between the two auxiliary plates 13. Two adjacent ends of the fastener 12 are also chamfered. The chamfered end of the fastener 12 can be clamped inside the fastening groove 11. A cylinder 16 is rotatably connected to the other end of the fastener 12. One end of the cylinder 16 passes through the through hole 7 and is fixedly connected to a fastening handle 17. A spring 15 is slidably connected and sleeved on the outer wall of the cylinder 16. The spring 15 is movably connected between the other end of the fastener 12 and the inner wall of the accommodating groove 6. Two groups of stabilizing members are fixedly connected to one side of the fan main body 1. Each group of stabilizing members includes two C-shaped blocks 19 that are far away from each other and arranged oppositely. A cushion block is fixedly connected to the inner wall of the C-shaped block 19. The sum of the heights of the cushion block and the fastening handle 17 is equal to the height of the C-shaped block 19. An adjusting handle 18 is fixedly connected to one end of the fastening handle 17. A plurality of equally spaced balls 14 are arranged at one end of the auxiliary plate 13. Each ball 14 is in rolling connection with the inner wall of the auxiliary groove.
[0033] In the initial state, the clamping plate 8 penetrates through the inside of the stable groove 10, the spring 15 is in a compressed state, and the fastener 12 passes through the fastening groove 11 and抵触 the clamping plate 8, which makes the four components of the clamping member 9, the installation part 2, the clamping plate 8, and the fan body 1 in a stable state. When it is necessary to remove the installation part 2, pull the two adjusting handles 18 respectively, and then the distance between the fastening handle 17 and the installation part 2 can be increased. The spring 15 is compressed again. When the distance between the fastening handle 17 and the installation part 2 exceeds the distance between the U-shaped block 19 and the installation part 2, rotate the adjusting handle 18 so that the fastening handle 17 rotates simultaneously. After the fastening handle 17 rotates 90°, it will be directly above the two cushion blocks. Release the adjusting handle 18, and the fastening handle 17 can be clamped between the two U-shaped blocks 19. At this time, the fastener 12 completely脱离 the inside of the fastening groove 11 and loses the pressure on the clamping plate 8 penetrating the inside of the stable groove 10. During the above process, the fastener 12 slides along the inner wall of the placement groove 6 throughout the process, and each ball 14 rolls along the inside of the auxiliary groove, reducing the friction that needs to be overcome when the fastener 12 is driven, that is, reducing the external force applied when pulling the adjusting handle 18, reducing the labor intensity, and facilitating the subsequent quick disassembly and assembly operations.
[0034] Embodiment 3, please refer to Figures 1 to 12 , on the basis of Embodiment 2, two convex blocks 36 that are far away from each other and symmetrically distributed are fixedly connected to the inner wall of the installation part 2. A second slot and a second installation groove 21 are provided on the outer wall of one side of the filter screen 3. The convex block 36 is in a sliding connection relationship with the inside of the second slot and the arc-shaped groove 2. The cross-sectional area of the second slot is equal to that of the convex block 36, and the two ends of the second slot and one end of the convex block 36 are chamfered. Two driving members 22 are provided on the outer wall of the other side of the filter screen 3. Each group of driving members 22 includes a connecting rod and two substrates that are spaced apart and symmetrically located. The connecting rod is fixedly connected between the two substrates, and each substrate is in a rotational connection relationship with the installation part 2. Four rubber strips 23 are provided on the outer wall of the other side of the installation part 2, and the rubber strips 23 are in a movable connection relationship with the substrates.
[0035] In the initial state, the convex block 36 is located at one end of the inner wall of the second installation groove 21. When it is necessary to remove the filter screen 3, first, the restriction of the quick-release mechanism 2 on the anti-vibration block 20 needs to be released. Then, overcome the friction between the rubber strip 23 and the substrate and pull the connecting rod, and the driving member 22 hidden on the installation part 2 can be shown. Rotate the two driving members 22 with both hands respectively, and the two convex blocks 36 can be rotated from the inside of the two second installation grooves 21 to the ends of the two second slots respectively. Then, pull the two driving members 22 outwards, and the filter screen 3 can be easily removed from the installation part 2. Similarly, no other tools are needed, and the whole operation process is simple and fast, which is beneficial to the improvement of work efficiency.
[0036] Embodiment 4, please refer to Figures 1 to 12On the basis of the third embodiment, there are two quick-release mechanisms 2, which are far away from each other and symmetrically distributed. A rectangular plate 1 24 is hinged on the outer wall of one side of the mounting portion 2. Both outer walls of the rectangular plate 1 24 are provided with slender grooves 29. A thin plate is slidably connected inside the slender groove 29. One end of the thin plate is fixedly connected to a rectangular plate 26. The other end of the thin plate is fixedly connected to a square block 27. The outer wall of the other side of the filter 3 is fixedly connected with two anti-sway blocks 20 that are far away from each other and symmetrically distributed. One end of the rectangular plate 26 is mutually clamped with the inside of the anti-sway block 20. The rectangular plate 26 is slidably connected to the inside of the rectangular plate 1 24. A through-type elliptical groove is provided on one side of the rectangular plate 1 24 and the rectangular plate 26. 30. A rough block 2 33 and two spaced-apart and symmetrically positioned rough blocks 1 32 are fixedly connected to one side of the rectangular plate 1 24. The connecting member includes a concave block 1 34 and two spaced-apart and symmetrically positioned concave blocks 2 35. The rough block 2 33 is clamped with the inside of the concave block 1 34, and the rough block 1 32 is clamped with the inside of the concave block 2 35. The bottom end of the rectangular plate 1 24 is fixedly connected with two fan-shaped blocks 31 that are far away from each other and symmetrically distributed. A plurality of fan-shaped grooves are provided on the outer wall of one side of the mounting portion 2. The fan-shaped blocks 31 are clamped with the inside of the fan-shaped grooves. An adjusting member 25 is fixedly connected to the top of the rectangular plate 1 24. The cross section of the adjusting member 25 is T-shaped. A plurality of equally spaced rough cushions 28 are fixedly connected to one side of the square block 27.
[0037] Initial state, as shown in the instruction manual Fig.10As shown, the rectangular plate 26 slides out from the inside of the rectangular plate 1 24, and one end of the rectangular plate 26 is simultaneously clamped in the anti-sway block 20. Since the anti-sway block 20 is fixedly connected to the filter 3, the position of the filter 3 can be limited to enhance stability and prevent the filter 3 from being displaced due to the vibration generated by the long-term operation of the fan body 1. At the same time, each rough block 1 32 and rough block 2 33 are respectively clamped in the inside of the concave block 2 35 and the concave block 1 34, and the concave block 2 35 and the concave block 1 34 are fixedly connected. On the fan body 1, it is equivalent to re-establishing a connection relationship between the fan body 1, the mounting portion 2 and the filter 3 through the setting of the connecting member and the quick-release mechanism 2. The outer surfaces of the rough block 1 32 and the rough block 2 33 are relatively rough. When the two are clamped in the inner concave block 2 35 and the inner concave block 1 34, there is a large static friction force, which greatly improves the stability. After the fastener 12 is completely separated from the inside of the fastening groove 11, it is necessary to drive the two square blocks 27 at the same time to make the rectangular plate 2 26 slide back to the rectangular plate 1 24 The inner cavity is rotated until the two elliptical grooves 30 are completely overlapped, and then the fixedly connected adjustment member 25 and the opened elliptical groove 30 are rotated along the hinge of the rectangular plate 1 24 and the mounting portion 2, thereby causing the rectangular plate 1 24 to deflect. During this process, the sector block 31 will gradually snap into the interior of the sector groove, and the rough block 1 32 and the rough block 2 33 will gradually break away from the interior of the concave block 2 35 and the concave block 1 34. When the sector block 31 is completely snapped into the interior of the sector groove, the rectangular plate 1 24 is also aligned with the mounting portion 2 A vertical relationship is formed, and the quick-release mechanism 2 is now simultaneously disconnected from the fan body 1 and the filter 3. Then, the two rectangular plates 24 are rotated simultaneously, so that the clamp 9 can be rotated to the end of the slot 1 and separated from the outer wall of the clamp 8. Then, the two rectangular plates 24 are pulled outwardly, so that the mounting part 2 can be separated from the air inlet 4, thereby achieving the purpose of easily removing the mounting part 2. That is, the quick-release mechanism 2 simultaneously plays the role of stabilizing the connection and serving as a removal tool. It has two uses in one, and no other tools are required, which simplifies the removal process and improves efficiency.
[0038] In actual use, pull the two adjusting handles 18 respectively. Then, the distance between the fastening handle 17 and the mounting portion 2 can be enlarged, and the spring 15 is compressed again. When the distance between the fastening handle 17 and the mounting portion 2 exceeds the distance between the U-shaped block 19 and the mounting portion 2, rotate the adjusting handle 18 so that the fastening handle 17 rotates simultaneously. After the fastening handle 17 rotates 90°, it will be directly above the two cushion blocks. Release the adjusting handle 18, and the fastening handle 17 can be clamped between the two U-shaped blocks 19. At this time, the fastener 12 completely disengages from the inside of the fastening groove 11 and loses the pressing force on the clamping plate 8 penetrating through the inside of the stabilizing groove 10. First, drive the two square blocks 27 simultaneously so that the second rectangular plate 26 slides back into the inner cavity of the first rectangular plate 24 until the two elliptical grooves 30 are completely overlapped. Then, along the hinge joint between the first rectangular plate 24 and the mounting portion 2, rotate the fixedly connected adjusting member 25 and the opened elliptical groove 30 simultaneously, so that the first rectangular plate 24 deflects. During this process, the sector block 31 will gradually be clamped into the inside of the sector groove, and the first rough block 32 and the second rough block 33 will also gradually disengage from the inside of the second concave block 35 and the first concave block 34. When the sector block 31 is completely clamped into the inside of the sector groove, the first rectangular plate 24 is also perpendicular to the mounting portion 2.至此, the second quick-release mechanism simultaneously disconnects from the fan main body 1 and the filter screen 3. Then, rotate the two first rectangular plates 24 simultaneously, and the clamping member 9 can be rotated to the end of the first slot and disengaged from the outer wall of the clamping plate 8 at the same time. Then, pull the two first rectangular plates 24 outwards, and the mounting portion 2 can be disengaged from the air inlet 4, achieving the purpose of easily removing the mounting portion 2. That is, the second quick-release mechanism simultaneously plays the role of stable connection and acts as a removal tool, serving two purposes with one object, without the need to借助 other tools, simplifying the removal process and improving efficiency.
