Problems solved by technology

The common shortcomings of the permanent magnet gyromagnetic rehabilitation devices manufactured by the technology provided are: 1. The proportion of magnetic flux leakage is too large; Clear; 3. The useful magnetic field is either mainly the horizontal component of the magnetic field, or mainly the vertical component of the magnetic field, and the ratio of the two magnetic field components is unbalanced
The main reason for the above shortcomings is that the magnetic circuit is a series structure, and the path of the magnetic flux through the space is too long

Embodiment Construction

[0011] Various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. figure 1 It is a structural schematic diagram of a rehabilitation device according to an embodiment of the present invention. The portable gyromagnetic rehabilitation device of the present embodiment comprises a cylindrical magnetic roller 1 with shaft extensions at both ends, a machine base 70 comprising a casing 7, left and right end covers 9, 8, and a non-magnetic bearing 10 positioned at the center of the right end cover. , the shaft joint 12 that connects motor 11 shaft extension end and magnetic roller left shaft extension, also has small cover 13. The so-called non-magnetic bearing means that the bearing is not magnetically conductive. The casing 7, left and right end caps 9, 8 are all made of non-metallic materials, the casing 7 is a hollow cylinder, the inside of which is used to accommodate the magnetic roller 1, and the left and right...

Abstract

A portable permanent rotating magnetic rehabilitation device comprises a magnetic roller (1) which is supported in a cylindrical shell (7) that is made of non-metal material, and the magnet roller has the same axis as the cylindrical shell and is driven by a motor (11), and the roller can rotate in the shell without hitting the inner wall of the shell. The device is characterized in that the magnetic roller is a cylinder which comprises five parallel layers along the axial direction of the roller, and the section of which is round; the middle third layer (4) and the first layer and the fifth layer (2 and 6) which are arranged on the surface side of the cylinder are made of ferromagnetic material; the second layer and the fourth layer (3 and 5) between the third layer and the first layer and between the third layer and the fifth layer are made of permanent magnet material, and the magnetization direction is vertical to the joint plane and points to or backs onto the clinging third layer. The device of the invention adopts double magnetic sources and magnetic circuit in parallel, thus shortening the magnetic circuit, bunching the working magnetic flux, balancing the magnetic flux weight composition, overcoming the defects of the magnetic circuit in series of the prior art, and making into the portable permanent rotating magnetic rehabilitation device.

Description

technical field [0001] The invention relates to a gyromagnetic rehabilitation device, in particular to a permanent magnet gyromagnetic rehabilitation device using permanent magnet double magnetic sources and parallel magnetic circuits. Background of the invention [0002] Gyromagnetic is an idiom that has been used in the medical and rehabilitation industries. In terms of engineering technology, the permanent magnet gyromagnetic rehabilitation device refers to a variable magnetic field generator that uses permanent magnetic materials as a magnetic source. The generated magnetic field is used for exposure To the designated part of the patient being rehabilitated to achieve the purpose of rehabilitation designated by the doctor. [0003] The permanent magnet gyromagnetic rehabilitation devices in the prior art, such as Chinese patent 01123435.0, all use series magnetic circuits. The common shortcomings of the permanent magnet gyromagnetic rehabilitation devices manufactured b...
