The specific embodiment
Below in conjunction with accompanying drawing, the utility model scheme is elaborated.
The flip body gap eliminator that the present embodiment provides, a side of the first flip body 15 is articulated with the second flip body 14, and opposite side is movable end, and the first rotor is driven and is done rotating relative to the second rotor by motor-driven transmission mechanism.This first flip body gap eliminator comprises lever 8, external broach spring 4, interior Compress Spring 5, is provided with the cylinder body 1 of upper and lower plunger shaft, the upper piston 2 that interconnects and be placed in respectively upper and lower plunger shaft and lower piston 3 and taps switch 16.The lower end of the first flip body 15 is provided with pin 10, and cylinder body 1 is placed on the second flip body 14.Lower piston chamber 12 is built-in with damping oil, and lower piston 3 is provided with an intercommunicating pore 9.This hole is for being communicated with the lower piston chamber 12 of being separated by lower piston 3.The two ends of interior Compress Spring 5 are connected with the bottom of cylinder body 1 with lower piston 3 respectively.Lever 8 is rotationally connected with on the second flip body 14, forms take to be rotationally connected a little first arm of force and second arm of force as stressed fulcrum.The two ends of external broach spring 4 connect respectively second arm of force of the second flip body 14 and lever 8, and the end of second arm of force is can butt upper piston 2, the first arm of force ends corresponding with pin 10, taps the top that switch 13 is located at upper piston.
The transmission mechanism that the present embodiment adopts is Worm and worm-wheel gearing or gear drive, and the first rotor connects and can relative to the second rotor, rotate around worm gear center of rotation with the worm gear in Worm and worm-wheel gearing; Or first rotor connect and can relative to the second rotor, rotate around output gear center of rotation with output gear in gear drive, as Fig. 7,8.
Further, this flip body gap eliminator also comprises sealing ring 6, and accent place and lower piston that sealing ring 6 is located at lower piston chamber are tightly connected.
Further, contact switch 13 is serially connected on the power circuit of motor, makes to tap switch 13 driving mechanism in closing course and can drive the first flip body 15 to rotate.
Further, lever 8 is provided with groove, and the corresponding end of external broach spring and lever second arm of force is provided with draw ring 17, and external broach spring 4 is realized and being connected with groove 18 clampings by draw ring 17 with second arm of force.
The flip body gap eliminator that the present embodiment provides the first flip body 15 will by vertical position turn to second flip body when laminating as shown in Figure 1, Figure 2, do not conflict yet first arm of force of lever 8 of the pin 10 of the first flip body 15 lower surfaces, the second arm of force conflict upper piston 2 of lever 8, the lower piston 3 that makes to be connected with upper piston 2 is pushed interior Compress Spring 5 and is carried out energy storage, now the volume due to lower piston chamber and upper cavity reduces, and forms high pressure in the below of damping oil 7 and upper cavity.When the first flip body 15 will turn to while leaving certain interval with the second flip body 14, as Fig. 3, Fig. 4, pin 10 start to conflict first arm of force of lever 8, second arm of force starts to depart from upper piston 2, the elastic potential energy of interior Compress Spring 5 discharge and the gas pressure of lower piston chamber, upper cavity under, upper lower piston starts to move up, and progressively presses close to until conflict and taps the contact of switch 13, as Fig. 5, Fig. 6 make motor, works on.Due to inertia, upper lower piston can continue a bit of distance that makes progress, and now the air pressure air pressure of lower piston chamber, upper cavity reduces, and interior Compress Spring 85 draws high to upper and lower piston is produced resistance and finally makes its decline reach poised state.When the first flip body 15 turn to horizontal level by vertical position, pin 10 departs from first arm of force of levers 8, and first arm of force that now 4, external broach spring can act on lever 8 makes it that upper lower piston is pressed in cylinder body 1 by equilbrium position.
