Description

Technical Field

[0001] The utility model relates to a permanent magnetic force unit with a magnetic pole four-quadrant layout. Background Art

[0002] At present, the permanent magnetic force unit used for magnetic adsorption of magnetic conductors adopts a layout structure in which the N pole and the S pole of the magnetic conductor are symmetrical. In the application occasions requiring the full magnetization and no magnetization conversion function, in the process from no magnetization to full magnetization or from full magnetization to no magnetization, firstly, the operating torque is too large when rotating the inner magnetic pole, and its rebound force has a safety hazard, and secondly, the inner magnetic pole processing requirements are high and difficult. The utility model aims to solve the above problems. Summary of the invention

[0003] The utility model adopts magnetic steel magnetic blocks distributed in four quadrants to form four poles, and only needs a very small rotation torque to easily complete the process from no magnetism to full magnetism or from full magnetism to demagnetization.

[0005] The outer magnetic pole, such as Figure 1 As shown, four magnetic blocks A, B, C, and D are distributed in four quadrants respectively. The four magnetic blocks are separated by non-magnetic materials. The cavity surrounded by the magnetic blocks and the non-magnetic materials is used to accommodate the magnets and the inner magnetic poles.

[0006] The inner magnetic pole has a cavity for accommodating the movable magnetic steel, and the center hole is connected to the rotating shaft.

[0007] The movable magnets are embedded in the inner magnetic pole cavity in pairs but with opposite polarities.

[0008] The rotating shaft is installed in the center hole of the outer magnetic pole and is used for positioning the inner magnetic pole.

[0009] The bearing and the bearing sleeve are installed on the outer magnetic pole housing to support the rotating shaft.

[0010] The cover plate is used to encapsulate the outer magnetic pole.

[0011] The fixed magnetic steel is arranged in the cavities on both sides of the outer magnetic pole.

[0012] The partition is used to wrap and fix the magnetic steel. BRIEF DESCRIPTION OF THE DRAWINGS
