Description

Technical Field

[0001] The utility model relates to the technical field of air suspension centrifugal fans, in particular to a stably installed clamping type air suspension centrifugal fan housing structure. Background Art

[0002] The air-suspended centrifugal fan is an integrated machine of a permanent magnet motor and a centrifugal fan, sharing a common shaft. The fan has a small impeller and a high speed to ensure high wind pressure and sufficient air volume. It is based on dynamic pressure air bearing technology and permanent magnet direct-drive motor technology. It uses air-suspended bearings to make the fan shaft self-suspended when rotating at high speed. The air-suspended centrifugal blower is different from the traditional Roots blower. Compared with the Roots blower, the air-suspended centrifugal blower reduces the friction loss of equipment operation and saves electricity. There is no mechanical wear, only wind friction loss, and the wind friction power consumption is within 200W. Compared with the magnetic suspension fan, the air suspension fan has no magnetic field circuit, is not afraid of emergency stop and power failure, and is more convenient to maintain.

[0003] The above-mentioned prior art solutions have the following defects: the shell structure of the existing air suspension centrifugal fan is difficult to disassemble, and when maintenance is required later, the shell cannot be quickly disassembled and assembled, which affects the maintenance efficiency.

[0010] Furthermore, a plurality of the engaging assemblies are arranged at equal intervals, the pull rod and the clamping block are fixedly connected, a spring is sleeved on the outer side of the pull rod, and the pull rod and the fixed block are movably connected via the spring.

[0011] By adopting the above technical solution, various components can be quickly connected through springs, pull rods and clamping blocks, and the structure is simple and easy to use.

[0012] Furthermore, there are four first limiting grooves, four first limiting plates and four first clamping grooves respectively distributed in an annular manner with equal intervals, the first limiting plate is snap-connected with the first limiting groove, and the first clamping groove is snap-connected with the clamping block.

[0013] By adopting the above technical solution and setting up an equidistant annular distribution, several more groups of structures can be added, which can improve the stability of the structure installation.

[0014] Furthermore, the base, the second limiting plate and the second card slot are respectively distributed in four equal intervals in a ring, the second limiting plate and the base are both engaged inside the mounting shell, the second card slot is engaged and connected with the card block, and the first card slot and the second card slot are of the same size and have the same specifications.

[0015] By adopting the above technical solution, through the connection of the card block and the card slot, multiple groups of structures are engaged at the same time, so the components can be quickly fixed and the installation is convenient.

[0016] In summary, the beneficial technical effects of the utility model are:

[0017] A snap-fitting assembly, a limit plate and a slot are used. Through the snap-fitting assembly, the block and the slot can be snapped together through the telescopic effect between the block and the spring, and each component can be snapped and fixed to achieve quick installation. At the same time, in order to ensure the stability of the structure, the limit plate can be installed inside the component during splicing to improve the stability of the connection, resulting in the effect of quick installation and stable use.
