Abstract
Description
Technical Field
[0001] This utility model relates to the field of magnetic levitation centrifugal blower technology, and in particular to a magnetic levitation centrifugal blower cabinet. Background Technology
[0002] A blower mainly consists of the following six parts: motor, air filter, blower body, air chamber, base, and oil drip nozzle. The blower relies on the eccentric rotation of the offset rotor inside the cylinder, and the volume change between the blades in the rotor slots draws in, compresses, and discharges air. During operation, the pressure difference of the blower automatically delivers lubricant to the oil drip nozzle, dripping into the cylinder to reduce friction and noise, while also preventing the gas inside the cylinder from flowing back. This type of blower is also called a vane blower.
[0003] Most existing magnetic levitation centrifugal blower cabinets face significant challenges in actual deployment: when the equipment is installed on uneven industrial workshop floors or in open-air sites with slight vibrations and soft foundations, the cabinet is prone to tilting or settling due to the lack of effective leveling and vibration damping mechanisms in its support structure. This lack of foundation stability directly leads to additional stress and vibration interference on precision components inside the cabinet, such as magnetic levitation bearings, high-speed motors, and control systems, which in turn causes serious problems such as decreased equipment operating accuracy, accelerated abnormal wear, and even instability of the control system, ultimately affecting the overall performance and service life of the blower.
[0004] To address these issues, we propose a magnetic levitation centrifugal blower cabinet. Utility Model Content
[0005] The purpose of this utility model is to solve the problems existing in the prior art and to propose a magnetic levitation centrifugal blower cabinet.
[0006] An embodiment of this utility model provides a magnetic levitation centrifugal blower cabinet, comprising: The cabinet body and the stabilizing base are provided. The cabinet body is equipped with a working cover door through multiple rotating hinges. Multiple support pads are also fixedly connected to the outer wall of the cabinet body through multiple disassembly and assembly components. The multiple support pads are installed symmetrically. Each of the multiple support pads is fixedly connected to a protective top plate through a buffer component. Multiple stabilization components; each stabilization component includes a working cavity opened within a stabilization base, a threaded sleeve rotatably connected within the working cavity, a working screw threadedly connected within the threaded sleeve, a stabilization suction cup fixedly connected to the end of the working screw away from the threaded sleeve, a working opening opened on the stabilization base, the working opening and the working cavity cooperating with each other, the working opening and the stabilization suction cup cooperating with each other, and a transmission component also installed within the working cavity.
[0007] Preferably, the transmission assembly includes a bevel gear one fixedly connected to the threaded sleeve, a working shaft rotatably connected inside the working cavity, one end of the working shaft rotatably passing through the working cavity, a bevel gear two fixedly connected to the end of the working shaft near the threaded sleeve, the bevel gear one and the bevel gear two meshing with each other, a limit plate fixedly connected to the inner side wall of the working cavity, and the working screw slidingly passing through the limit plate.
[0008] Preferably, the buffer assembly includes a buffer slide cylinder fixedly connected to the support pad, a buffer spring fixedly connected inside the buffer slide cylinder, a buffer connecting rod fixedly connected to the other end of the buffer spring, the buffer connecting rod and the buffer slide cylinder being slidably connected and installed, and the end of the buffer connecting rod away from the buffer slide cylinder being fixedly connected and installed to the protective top plate.
[0009] Preferably, the disassembly assembly includes a disassembly connecting plate fixedly connected to the support plate.

[0010] Preferably, a working handle is fixedly connected to the working shaft, the working handle being disc-shaped, and the working handle and the working shaft cooperating with each other.
[0011] Preferably, a working handle is fixedly connected to the working cover, and a protective coating is sprayed on the working handle, with the protective coating adhering to the outer wall of the working handle.
[0012] Compared with the prior art, the beneficial effects of this utility model are: In this utility model: 1. Through the cooperation of the cabinet body, stabilizing base, threaded sleeve, working screw, stabilizing suction cup, bevel gear one, working shaft, bevel gear two, and limiting plate, the operator only needs to rotate the working shaft to drive the threaded sleeve to rotate through the bevel gear transmission, thereby driving the working screw to move up and down, thereby adjusting the height of the stabilizing suction cup and making it firmly attached to the ground, realizing the cabinet's quick and convenient leveling and reliable support on rugged or uneven working surfaces, effectively isolating the vibration and tilt risks caused by uneven ground.
[0013] 2. Through the cooperation of support pads, buffer slides, buffer springs, buffer linkages, and protective top plates, when external impacts or vibrations are transmitted to the cabinet, the buffer components can absorb energy through the compression and rebound of the springs, reducing interference with the precision components inside the cabinet. At the same time, the protective top plate provides additional protection, further enhancing the overall stability and vibration resistance of the cabinet and extending the service life of the equipment.

Detailed Implementation
[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a magnetic levitation centrifugal blower cabinet, comprising: The cabinet body 1 and the stabilizing base 2 are assembled together. A working cover 3 is mounted on the cabinet body 1 via multiple rotating hinges. A working handle is fixedly connected to the working cover 3. The working handle is coated with a protective coating that adheres to the outer wall of the handle, thereby improving its durability and operational comfort. Multiple support plates 4 are also fixedly connected to the outer wall of the cabinet body 1 via multiple disassembly and assembly components. These components include disassembly and assembly connecting plates 16 fixedly connected to the support plates 4. The disassembly and assembly connecting plates 16 cooperate with the cabinet body 1. Multiple bolt holes are provided on the disassembly and assembly connecting plates 16, each containing a disassembly and assembly bolt, ensuring stable installation while facilitating easy assembly. Staff disassembled and maintained the equipment; multiple support pads 4 were symmetrically installed, and a protective top plate 5 was fixedly connected to each of the multiple support pads 4 through a buffer assembly. The buffer assembly included a buffer slide cylinder 13 fixedly connected to the support pad 4, a buffer spring 14 fixedly connected inside the buffer slide cylinder 13, and a buffer connecting rod 15 fixedly connected to the other end of the buffer spring 14. The buffer connecting rod 15 and the buffer slide cylinder 13 were slidably connected and installed. The end of the buffer connecting rod 15 away from the buffer slide cylinder 13 was fixedly connected and installed to the protective top plate 5. Thus, when an external impact or vibration occurs, the buffer spring 14 can be compressed and rebounded, effectively absorbing energy and reducing interference to the internal components of the cabinet. Multiple stabilization components are included. Each stabilization component comprises a working cavity within a stabilization base 2. A threaded sleeve 6 is rotatably connected within the working cavity. A working screw 7 is threadedly connected to the threaded sleeve 6. A stabilization suction cup 8 is fixedly connected to the end of the working screw 7 furthest from the threaded sleeve 6. A working opening is provided on the stabilization base 2, which cooperates with the working cavity and the stabilization suction cup 8. This allows the working screw 7 to extend or retract the stabilization suction cup 8 when it moves, adapting to different ground conditions. A transmission component is also installed within the working cavity. The transmission component includes a bevel gear 9 fixedly connected to the threaded sleeve 6, and a working shaft is rotatably connected within the working cavity. 10. One end of the working shaft 10 rotates through the working cavity. A working handle is fixedly connected to the working shaft 10. The working handle is disc-shaped. The working handle and the working shaft 10 cooperate with each other to facilitate manual operation by the operator. A bevel gear 11 is fixedly connected to the end of the working shaft 10 near the threaded sleeve 6. The bevel gear 9 and the bevel gear 11 mesh with each other, so that when the working shaft 10 is rotated, the threaded sleeve 6 can be rotated through the bevel gear transmission. A limit plate 12 is also fixedly connected to the inner side wall of the working cavity. The working screw 7 slides through the limit plate 12, thereby limiting the working screw 7 so that it can only move up and down and cannot rotate.
[0018] In the process of using this utility model, the operator first places the stabilizing base 2 on the target working surface. According to the flatness of the ground, the operator rotates the working handle on the working shaft 10, causing the working shaft 10 to drive the fixedly connected bevel gear 11 to rotate. Due to the meshing transmission between bevel gear 9 and bevel gear 11, bevel gear 9 rotates accordingly, driving the threaded sleeve 6 to rotate in the working cavity. The rotation of the threaded sleeve 6 causes the working screw 7, which is threaded inside it, to move up and down linearly under the limiting action of the limiting plate 12, thereby driving the stabilizing suction cup 8 to move downward until it is in close contact with the ground and adsorbs, realizing the stable leveling and reliable support of the cabinet. At the same time, when the cabinet is subjected to external vibration or impact, the protective top plate 5 transmits the force to the buffer connecting rod 15. The buffer connecting rod 15 slides in the buffer slide cylinder 13 and compresses the buffer spring 14. The energy is absorbed through the buffering effect of the spring, reducing the impact on the precision components inside the cabinet body 1 and ensuring the smooth operation of the blower. In addition, the support plate 4 and the protective top plate 5 can be easily disassembled and maintained by disassembling and assembling the connecting plate 16 and the bolts, which improves the practicality and maintainability of the equipment.
[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
