Abstract

The invention relates to a magnetorheological fluid damping type human body muscle strength rehabilitation instrument. A magnet exciting coil is placed in a magnetic conductivity cylinder through a locating ring, left and right end covers are fixedly connected with two ends of the magnetic conductivity cylinder respectively, polytetrafluoroethylene seal rings are placed between the left and right end covers and the magnetic conductivity cylinder respectively, left and right shear plates are respectively placed in the middle of the locating ring, the left and right shear plates are connected with the left and right end covers in a matching and sealing mode through left and right cylindrical bars respectively, the left and right cylindrical bars are located on the left and right shear plates and penetrate through the left and right end covers respectively, left and right right-angle plates are fixedly connected with the left and right cylindrical bars respectively, and a magnetorheological fluid is filled in the magnetic conductivity cylinder. According to the magnetorheological fluid damping type human body muscle strength rehabilitation instrument, under the magnetic field action, the shearing resistance required by a rehabilitation training continuity can be continuously adjusted through the adjustment of electric current according to recovery conditions of muscle tension of a patient, and a secondary injury caused by the fact that the patient overestimates or underestimates the muscle tension during the training and treating process can be avoided. The magnetorheological fluid damping type human body muscle strength rehabilitation instrument has the advantages that the cost is low, the adjustable range is wide, the operation, assembly and disassembly are convenient, the humanization and intelligentization can be further achieved, and the like.

Description

technical field [0001] The invention relates to a human muscle strength rehabilitation instrument, in particular to a magneto-rheological fluid damping type human muscle strength rehabilitation instrument. Background technique [0002] The magnetorheological fluid is mainly composed of carrier liquid, magnetic particles and various additives. The liquid exhibits low-viscosity Newtonian fluid characteristics when there is no external magnetic field. Once an external magnetic field is added, it will appear as a high-viscosity semi-solid. state, so that the shear strength increases dozens of times; but after the external magnetic field is removed, the liquid returns to the previous Newtonian fluid state, so that the shear strength rapidly decreases to the order of ordinary fluids. Therefore, components made of magnetorheological fluid have the advantages of adjustable shear strength, fast response, low power consumption, and simple structure, and have broad application pros...
