Description

Technical Field

[0001] This utility model relates to the technical field of quick disassembly and assembly mechanisms, specifically a quick disassembly and assembly mechanism for centrifugal fans. Background Technology

[0002] There are two major safety hazards in the disassembly and assembly of traditional centrifugal fans: First, the risk of handling heavy objects. Components such as impellers and motors can weigh tens of kilograms. When handled manually, they are prone to being bumped or falling, which can lead to personal injury or equipment damage. Second, the risk of operational errors. Bolt tightening must be carried out in a specific torque sequence. Traditional manual operation is prone to uneven torque, which can lead to air leakage or increased vibration during subsequent operation.

[0003] Existing centrifugal fans use quick-release mechanisms. Once the installation hole positions are determined, if the height needs to be adjusted, personnel must constantly adjust the fan's position, which is very inconvenient, resulting in low installation efficiency and high labor intensity.

[0004] To address this, a quick-assembly and disassembly mechanism for centrifugal fans is proposed. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a quick disassembly and assembly mechanism for centrifugal fans.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quick disassembly and assembly mechanism for a centrifugal fan, comprising a fan, a first bracket fixedly connected to the bottom of the fan, a lifting assembly fixedly connected to the bottom of the first bracket, and a load-bearing plate installed at the bottom of the lifting assembly; The lifting assembly includes a cylinder, the output end of which is connected to a connecting block. A lifting plate is fixedly connected to the top of the connecting block. Vertical plates are installed on both sides of the bottom wall of the lifting plate. Inclined grooves are opened on the surface of both vertical plates. A sliding shaft is slidably connected inside the inclined groove. One end of the sliding shaft is fixedly connected to one side of the connecting block.

[0007] The bottom of the cylinder is fixedly connected to a second bracket, and the bottom of the second bracket is fixedly connected to the surface of the load-bearing plate.

[0008] Preferably, the bottom wall of the lifting plate is fixedly connected to a telescopic shaft, and the bottom of the telescopic shaft is fixedly connected to the surface of the load-bearing plate.

[0009] Preferably, a limiting rod is fixedly connected to the surface of the load-bearing plate, and the connecting block slides on the surface of the limiting rod.

[0010] Preferably, the fan is equipped with a housing on both sides, and a retaining shaft runs through the surface of the housing, with one end of the retaining shaft mounted on the surface of the fan.

[0011] Preferably, the surface of the fan is fixedly connected to limit rings twice, and one end of the retaining shaft is rotatably connected to the inner ring of the limit ring.

[0012] Preferably, an anti-slip pad is attached to the bottom of the load-bearing plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. When the output end of the cylinder extends or retracts, the connecting block moves accordingly. When the cylinder moves the connecting block, the sliding shaft slides in the inclined groove. Due to the inclination angle of the inclined groove, the sliding shaft will cause the vertical plate and the lifting plate to move in a certain tilt or horizontal direction. This allows the height of the fan to be adjusted while the load-bearing plate is being raised and lowered. This eliminates the need for construction personnel to constantly adjust the position of the fan, which is very inconvenient to operate, resulting in low installation efficiency and high labor intensity.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0017] The embodiments of this utility model will be described below based on its overall structure.

[0018] Please see Figure 1 - Figure 4 A quick disassembly and assembly mechanism for a centrifugal fan includes a fan 1, a first bracket 4 fixedly connected to the bottom of the fan 1, a lifting assembly 6 fixedly connected to the bottom of the first bracket 4, and a load-bearing plate 5 installed at the bottom of the lifting assembly 6. The lifting assembly 6 includes a cylinder 61, the output end of which is connected to a connecting block 63. A lifting plate 68 is fixedly connected to the top of the connecting block 63. Vertical plates 65 are installed on both sides of the bottom wall of the lifting plate 68. Inclined grooves 66 are opened on the surface of both vertical plates 65. A sliding shaft 64 is slidably connected inside the inclined groove 66. One end of the sliding shaft 64 is fixedly connected to one side of the connecting block 63.

[0019] When the output end of cylinder 61 extends or retracts, it will drive the connecting block 63 to move accordingly. When cylinder 61 drives the connecting block 63 to move, the sliding shaft 64 will slide in the inclined groove 66. Due to the inclination angle of the inclined groove 66, the sliding of the sliding shaft 64 will drive the vertical plate 65 and the lifting plate 68 to move in a certain degree of tilt or horizontal movement, so that the load-bearing plate 5 can adjust the height of the fan 1 while lifting and lowering. This eliminates the need for construction personnel to constantly adjust the position of the fan 1, which is very inconvenient to operate, resulting in low installation efficiency and high labor intensity.

[0020] Please see Figure 3 and Figure 4 A second bracket 62 is fixedly connected to the bottom of cylinder 61, and the bottom of the second bracket 62 is fixedly connected to the surface of the load-bearing plate 5. Telescopic shafts 67 are fixedly connected to the periphery of the bottom wall of the lifting plate 68, and the bottom of the telescopic shafts 67 is fixedly connected to the surface of the load-bearing plate 5. A limit rod 69 is fixedly connected to the surface of the load-bearing plate 5, and the connecting block 63 slides on the surface of the limit rod 69. A housing 2 is installed on both sides of the fan 1, and a retaining shaft 8 penetrates the surface of the housing 2. One end of the retaining shaft 8 is installed on the surface of the fan 1. Limit rings 3 are fixedly connected to both sides of the surface of the fan 1, and one end of the retaining shaft 8 is rotatably connected to the inner ring of the limit ring 3. An anti-slip pad 7 is attached to the bottom of the load-bearing plate 5. The second bracket 62 provides rigid support for cylinder 61, ensuring that cylinder 61 is always in the preset working position, and its output end can accurately... The cylinder 61 drives the connecting block 63 and the lifting plate 68 to move, preventing the load-bearing plate 5 from jamming, shifting, or deviating in height due to the displacement of the cylinder 61. When the cylinder 61 drives the lifting plate 68 to rise or fall, the telescopic shaft 67 will extend or shorten synchronously. Through its own rigid constraint, it limits the horizontal displacement of the lifting plate 68. The limit rod 69 can provide a stable guide for the connecting block 63, preventing it from shifting during movement and affecting the subsequent use effect. When it is necessary to disassemble the outer shell 2, the protrusion on its surface and the groove on the surface of the outer shell 2 are engaged by rotating the locking shaft 8, and then the outer shell 2 is pulled to complete the disassembly operation. The limit ring 3 can limit the locking shaft 8 from shifting or moving during rotation, which would affect the subsequent use effect. The anti-slip pad 7 can improve the anti-slip effect of the overall equipment.

[0021] Working principle: When the output end of cylinder 61 extends or retracts, it drives the connecting block 63 to move accordingly. When cylinder 61 drives the connecting block 63 to move, the sliding shaft 64 will slide in the inclined groove 66. Due to the inclination angle of the inclined groove 66, the sliding of the sliding shaft 64 will cause the vertical plate 65 and the lifting plate 68 to tilt or move horizontally, so that the load-bearing plate 5 can be raised and lowered at the same time, and the height of the fan 1 can be adjusted. This eliminates the need for construction personnel to constantly adjust the position of the fan 1, which is very inconvenient to operate, resulting in low installation efficiency and high labor intensity. The second bracket 62 provides rigid support for cylinder 61, ensuring that cylinder 61 is always in the preset working position, and its output end can accurately drive the connecting block 63 and the lifting plate 68 to move, avoiding the need for constant adjustment of the fan 1 position. The displacement of cylinder 61 causes the lifting plate 5 to jam, shift, or deviate in height. When cylinder 61 drives the lifting plate 68 to rise or fall, the telescopic shaft 67 will extend or shorten synchronously. Through its own rigid constraint, the horizontal displacement of the lifting plate 68 is limited. The limit rod 69 can provide a stable guide for the connecting block 63 to prevent it from shifting during movement and affecting the subsequent use effect. When it is necessary to disassemble the outer shell 2, the protrusion on its surface and the groove on the surface of the outer shell 2 are engaged by rotating the locking shaft 8. Then the outer shell 2 is pulled to complete the disassembly operation. The limit ring 3 can limit the shift or movement of the locking shaft 8 during rotation, which would affect the subsequent use effect. The anti-slip pad 7 can improve the anti-slip effect of the overall equipment.
