Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Example one

Referring to fig. 1-2, an arm strength stick for running and body building comprises two handles 1, wherein the handles 1 are provided with anti-skidding lines, so that a palm is prevented from skidding during body building, the body building effect is reduced, and the two handles 1 are back to back and fixedly connected with hanging belts at two ends, so that the arm strength stick is conveniently hung on a wall.

Spring pipe 2 of the equal fixedly connected with of two 1 relative one ends of handle, the relative one end fixed connection of two spring pipes 2 is at 6 both ends of elastomer, and the 2 internal surface sealing fixedly connected with insulating layers 3 of spring pipe, insulating layers 3 adopt rubber insulation material to make.

Two conductive layers 4 are fixedly connected to two opposite sides of the inner surface of the insulating layer 3, and are hermetically wrapped with an electrorheological fluid filler 5, the electrorheological fluid filler 5 is composed of electrorheological fluid which is a suspension liquid under a common condition and is composed of solid particles with high dielectric constant uniformly dispersed in insulating oil with low dielectric constant, the electrorheological fluid can be converted from a liquid state to a solid state under the action of an electric field, and the shear yield strength of the electrorheological fluid is continuously increased along with the enhancement of the electric field within a certain range.

Thereby increasing the bending difficulty, equivalently improving the elastic coefficient of the spring tube 2 and enlarging the whole elastic force stress range; if a wrong force occurs at this time, the spring tube 2 will rebound, but the electrorheological fluid filler 5 has no rebound characteristic, and the strong shearing stress of the electrorheological fluid filler becomes the rebound resistance of the spring tube 2, so that the spring tube 2 is forced to be only slowly restored to the original state, and the safety is effectively improved.

Electrorheological fluids obturator 5 electric connection has two conducting
