Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention program is described in detail.

The flip body gap eliminator that the present embodiment provides, the 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 by motor-driven transmission mechanism and does rotating relative to the second rotor.This first flip body gap eliminator comprise lever 8, external broach spring 4, interior Compress Spring 5, be provided with upper and lower plunger shaft cylinder body 1, be interconnected and be placed in the upper piston 2 of upper and lower plunger shaft and lower piston 3 and touch switch 16 respectively.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 lower piston 3 and cylinder body 1 respectively.Lever 8 is rotationally connected with on the second flip body 14, and being formed to be rotationally connected is a little first arm of force and second arm of force of fulcrum force.The two ends of external broach spring 4 connect second arm of force of the second flip body 14 and lever 8 respectively, and the end of second arm of force can abut upper piston 2, and the first arm of force end is corresponding with pin 10, and touch switch 16 is located at the top of upper piston.

The transmission mechanism that the present embodiment adopts is Worm and worm-wheel gearing or gear drive, and the first rotor and the worm gear in Worm and worm-wheel gearing connect and can rotate relative to the second rotor around worm gear wheel center; Or first rotor and the output gear in gear drive connect and can rotate relative to the second rotor around output gear center of rotation, as Fig. 7,8.

Further, this first flip body gap eliminator also comprises sealing ring 6, and the accent place in lower piston chamber is located at by sealing ring 6 and lower piston is tightly connected.

Further, contact switch 13 is serially connected on the power circuit of motor, makes touch switch 13 driving mechanism in closing course that the first flip body 15 can be driven 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 realizes being connected with groove 18 clamping 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 fit with the second flip body time as shown in Figure 1, Figure 2, first arm of force of the pin 10 of the first flip body 15 lower surface conflict lever 8 not yet, second arm of force conflict upper piston 2 of lever 8, make the lower piston 3 be connected with upper piston 2 push interior Compress Spring 5 and carry out energy storage, now because the volume of lower piston chamber and upper cavity reduces, in the below of damping oil 7 and upper cavity, form high pressure.When the first flip body 15 will turn to leave certain interval with the second flip body 14 time, as Fig. 3, Fig. 4, pin 10 starts to conflict first arm of force of lever 8, second arm of force starts to depart from upper piston 2, interior Compress Spring 5 elastic potential energy release and lower piston chamber, upper cavity gas pressure under, upper lower piston starts to move up, and progressively presses close to until the contact of conflict touch switch 13, as Fig. 5, Fig. 6 make motor work on.Due to inertia, upper lower piston can continue upwards a bit of distance, and now the air pressure air pressure of lower piston chamber, upper cavity reduces, and interior Compress Spring 85 draws high upper and lower piston generation resistance and finally makes it decline and reaches poised state.When the first flip body 15 turn to horizontal level by vertical position, pin 10 departs from first arm of force of lever 8, and first arm of force that now 4, external broach spring can act on lever 8 makes it be pressed in cylinder body 1 by equilbrium position by upper lower piston.
