a cylinder 8 is fixedly arranged on the inner wall of the inner cavity 3, the cylinder 8 is perpendicular to the plane of the second partition plate 5, two electrified flat plates 9 are arranged on the cylinder 8 in a penetrating manner, the two electrified flat plates 9 can slide relative to the cylinder 8, an insulating sleeve 10 is sleeved outside each electrified flat plate 9 to ensure that the charges on the electrified flat plates 9 are not conducted to the outside, one sides, far away from each other, of the two insulating sleeves 10 are fixedly connected with an extension spring 11, one end, far away from the corresponding insulating sleeve 10, of each extension spring 11 is fixedly connected with the inner wall of the inner cavity 3, so that the insulating sleeves 10 and the electrified flat plates 9 are close to the side wall of the corresponding position of the inner cavity 3 under the action of the extension springs 11, each holding rod 2 is provided with two piezoelectric elements 12, the two piezoelectric elements 12 are respectively positioned on two sides of the cylinder 8, each piezoelectric element 12 is glued with a layer of rubber pad 18, the rubber pads 18 can enable, meanwhile, the insulating property of the rubber pad 18 prevents the electric charge on the surface of the piezoelectric element 12 from being conducted to the hands of the exerciser;
two sliding grooves 13 are symmetrically arranged on the inner wall of the inner cavity 3, a sliding block 14 is slidably connected in each sliding groove 13, each sliding block 14 is fixedly connected with a connecting block 15, one side of each connecting block 15, which is close to the first partition plate 4, is fixedly glued with a plug 17, one side of each connecting block 15, which is far away from the first partition plate 4, is rotatably connected with a connecting rod 16 by using a pin shaft, one end of each connecting rod 16, which is far away from the connecting block 15, is rotatably connected with an insulating sleeve 10 at a corresponding position by using a pin shaft, so that the sliding energy of the insulating sleeve 10 on the cylinder 8 can drive the plug 17 to move away from or close to the first partition plate 4, one side of the first partition plate 4, which is close to the cylinder 8, is, when the connecting rod 16 rotates to enable the plug 17 to leave the through hole 7, the air bag 20 can be properly compressed, so that the plug 17 can normally move, and the situation that the plug 7 cannot move due to the fact that a compression space is not formed on one side, close to the cylinder 8, of the first partition plate 4 is avoided.
An iron plate 19 is glued and fixed in the middle of the cylinder 8, the iron plate 19 is parallel to the plane where the two electrified flat plates 9 are located, the iron plate 19 can be made of conductive materials such as iron, and the like, and can generate an electrostatic shielding effect on the electrified flat plates 9 on the two sides, so that the interaction of electric fields generated by the two electrified flat plates 9 is avoided.
The plug 17 is in a conical structure, the through holes 7 are cylindrical holes, each plug 17 is concentrically arranged with the through hole 7 at the symmetrical position, when electric charges generated by the piezoelectric element 12 are small and the plug 17 cannot be completely separated from the through hole 7, a small gap exists between the plug 17 and the through hole 7, in this state, the gap at the through hole 7 is small, so that the oil flow in unit time is small, namely the flow velocity of the oil passing through the through hole 7 is slow, and at the moment, the arm power device can only be bent at a slow speed;
two holding rods 2 dislocation 90 settings, the axis line of four wire hose 6 is the rhombus under initial condition promptly, the holding rod 2 combined action at both ends, only when holding the holding rod 2 of both sides simultaneously and making end cap 17 wherein all not offset with through-hole 7, the strong spring of body-building person's bending normally accomplishes body-building, when any holding rod 2 the condition of taking off the hand, corresponding end cap 17 just can be rapid offsets with through-hole 7, make the fluid in wire hose 6 can't continue to flow, make the strength of arm unable deformation that continues to appear and injure the body-building person.
The inner cavity 3 and the steel wire hose 6 are filled with oil with high viscosity; the steel wire hose 6 is a PVC steel wire pipe which has strong positive and negative pressure resistance; when the arm strength device is not used, the two insulating sleeves 10 in the holding rod 2 are far away from each other under the action of the extension spring 11, at the moment, the two connecting rods 16 are parallel to the electrified flat plate 9, the plugs 17 are tightly abutted against the through holes 7, oil on two sides of the first partition plate 4 cannot flow from the through holes 7, namely, liquid in the steel wire hose 6 cannot flow through the through holes 7; when the strong spring 1 is bent, the two steel wire hoses 6 are respectively in a stretching state and a squeezing state (the two steel wire hoses 6 communicated with the same holding rod 2 are taken as an example, the same is true below), so that in the state, the steel wire hoses 6 cannot be bent by external force, and the strong spring 1 cannot be bent by the external force;
when a body builder uses the device for body building, the holding rod 2 is tightly held by two hands, pressure is generated on the piezoelectric element 12 on the holding rod 2, opposite charges are gathered on two surfaces of the piezoelectric element 12 when the piezoelectric element 12 is under pressure, the voltage on two sides of the piezoelectric element 12 is larger when the pressure is larger, when the piezoelectric element 12 in the device is extruded, the same charge as the charged flat plate 9 is gathered on one side close to the charged flat plate 9, at the moment, the piezoelectric element 12 generates repulsive force on the charged flat plate 9, the two charged flat plates 9 are pushed to mutually approach, the two connecting rods 16 are driven to rotate, the sliding block 14 is driven to slide in the sliding groove 13, so that the connecting block 15 and the plug 17 gradually leave away from the first partition plate 4, and when the plug 17 is separated from the through hole 7, oil in the two steel wire hoses 6 can mutually circulate through the through hole 7; when the arm force device is bent, one steel wire hose 6 is positioned on the inner side of the bend and is in a squeezing state, the other steel wire hose 6 is positioned on the outer side of the bend and is in a stretching state, and oil in the steel wire hose 6 in the squeezing state can flow into the steel wire hose 6 in the stretching state; the arm power exerciser can normally finish the arm power exercise operation.
When the body builder causes the holding rod 2 to be out of hand due to external reasons, the piezoelectric element 12 loses the pressure effect and enables the two sides of the piezoelectric element to recover to be neutral, the electrified flat plate 9 and the insulating sleeve 10 recover to the initial state rapidly under the effect of the extension spring 11, the plug 17 offsets with the through hole 7 again, oil in the two steel wire hoses 6 cannot circulate, namely the two steel wire hoses 6 cannot continue to generate bending deformation, the strong spring 1 stops at the current state, the arm strength is prevented from recovering the initial shape under the elastic effect of the strong spring 1 to hit the body builder, and the safety of the body builder is further guaranteed.
Although the terms of strong spring 1, holding rod 2, inner cavity 3, first partition plate 4, second partition plate 5, steel hose 6, through hole 7, cylinder 8, charged plate 9, insulating sleeve 10, extension spring 11, piezoelectric element 12, sliding groove 13, sliding block 14, connecting block 15, connecting rod 16, plug 17, rubber pad 18, iron plate 19, air bag 20, etc. are used more herein, the possibility of using other terms is not excluded.
