specific Embodiment approach 1

[0007] Specific implementation mode one: combine figure 1 Describe a displacement amplifying device in this embodiment, the device includes a lever structure 1 and a hydraulic cylinder mechanism 2, the lever structure 1 includes a top column 7, a lever 8 and a support shaft 9, and the hydraulic cylinder mechanism 2 includes a first piston 3, a second Two piston 4, connecting rod 5, hydraulic oil 6, hydraulic cylinder 11 and oil outlet pipe 10; the cross section of hydraulic cylinder 11 is an inverted 'T' shape, the cross section of oil outlet pipe 10 is 'L' shape, and the lever 8 passes through Support shaft 9, and the axis of lever 8 is perpendicular to the axis of support shaft 9, the upper end of push column 7 is arranged below the left end of lever 8, the upper end of hydraulic cylinder 11 is open, and one end of oil outlet pipe 10 is in the middle of the lower end surface of hydraulic cylinder 11 Sealed communication, the inner radius R of the upper part of the hydraulic ...

specific Embodiment approach 2

[0008] Specific implementation mode two: combination figure 1 Describe a displacement amplification device in this embodiment, the distance D from the intersection point of the lever 8 and the support shaft 9 to the connecting rod 5 is two to twenty times the distance d from the intersection point of the lever 8 and the support shaft 9 to the top column 7 , through the lever structure 1, the displacement of the right end of the lever 8 to the connecting rod 5 is increased by two to twenty times compared with the displacement of the push column 7, and the others are the same as in the first embodiment.

specific Embodiment approach 3

[0009] Specific implementation mode three: combination figure 1 Describe a displacement amplification device in this embodiment, the inner radius R of the upper part of the hydraulic cylinder 11 is two to ten times the radius r of the oil outlet pipe 10, and the displacement of the second piston 4 moving to the right through the hydraulic cylinder mechanism 2 is the second Two to ten times the displacement of the downward movement of the piston 3, and the others are the same as in the first embodiment.

[0010] working principle

[0011] When the present invention works, push the top column 7 to move upward, the top column 7 drives the left end of the lever 8 to move upward, and the right end of the lever 8 moves downward through the principle of leverage, and then pushes the first piston 3 to move downward. Since the hydraulic oil 6 is incompressible, Push the piston 4 to move to the right, and the displacement of the second piston to the right is more than four times the di...
