[0002] An industrial blower is a blade rotary gas compression machine. The gas is sucked in through the suction chamber and the impeller works on the blades to increase the gas pressure, velocity and temperature. Then, the kinetic energy is converted into pressure energy through the diffuser to further increase the pressure.

[0003] At present, most of the samarium cobalt magnets used in industrial blowers are fixed to the shaft of the blower by gluing, such as a rotor assembly, an outer rotor motor and a blower disclosed in Chinese patent announcement number CN218569954U. However, the samarium cobalt magnets and the shaft are not easy to separate after gluing, which makes it more troublesome for maintenance personnel to replace the samarium cobalt magnets. Utility Model Content

[0008] Preferably, a first through hole is opened inside the mounting plate, and the inner wall of the first through hole contacts the surface of the bolt; a second through hole is opened inside the bolt, and the inner wall of the second through hole and the bottom of the mounting plate are both fitted with hollow columns, and one end of the hollow column close to the rotating shaft is fixedly connected to a limiting plate, and the surface of the limiting plate contacts the surface of the bolt; a metal spring is fixedly connected to the inner wall of the hollow column, and the surface of the metal spring contacts the surface of the bolt.

[0009] Preferably, the elastic force of the metal spring is greater than the sum of the gravity of the limiting plate and the hollow column.

[0010] Preferably, a baffle is fixedly connected to the inner wall of the groove, the baffle is located above the bolt, and a third through hole is opened inside the baffle.

[0011] Preferably, the center of the third through hole and the center of the bolt are on the same vertical line.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) The utility model is provided with a cylinder, an arc plate, a T-slot, a T-column, a groove, a locking bracket and a locking groove, wherein when the annular groove on the locking bracket is misaligned with the steel ball, the steel ball is fixed in the locking groove by a bolt, and the magnetic steel body can be fixed on the cylinder by the cooperation of the arc plate, the T-slot, the T-column, the locking bracket and the locking groove. When the annular groove is aligned with the steel ball, the steel ball can slide into the annular groove and separate from the locking groove, thereby making the magnetic steel body directly separate from the cylinder. At the same time, by the cooperation of the bolt and the threaded cylinder, the user can change the position of the annular groove by turning the bolt. Then, by the cooperation of the cylinder, the arc plate, the T-slot, the T-column, the groove, the locking bracket and the locking groove, the samarium cobalt magnet and the rotating shaft can be easily disassembled and assembled, thereby facilitating the maintenance personnel to replace the samarium cobalt magnet.

[0014] (2) The utility model provides a first through hole, a second through hole, a hollow column, a limit plate and a metal spring. When the hollow column is inserted into the second through hole, the metal spring and the limit plate cooperate to clamp the hollow column in the second through hole. The hollow column prevents the bolt in the threaded barrel from rotating, and the bolt is not easy to rotate after being vibrated. Therefore, when the industrial blower vibrates, the position of the annular groove will not change due to vibration. BRIEF DESCRIPTION OF THE DRAWINGS
