It will not be interfered between first gear.The effect of telescopic fixing rod is to prevent second gear in moving process and in the present invention
Two scroll springs interfere.Pass through in the present invention in the space of upper piston plate and lower piston plate both sides full of high-pressure helium
Can inherently damping be played the role of to push rod.
In the present invention if when the shock that is subject to of upper backup pad is larger；If work on buffer spring to upper piston plate
When the elastic strength of buffer spring is larger；Larger impact will cause integrated model damage to lose its effect；So at this time
It is required that the elastic strength of the buffer spring to work on buffer spring to upper piston plate is smaller, buffer spring is easier to become
Shape；Larger impact is buffered by moderate finite deformation；But when the shock that upper backup pad is subject to is larger；Second gear is delivered to
Rotary force on teeth installation wheel is larger；I.e. flight is possible to rotate a larger angle；Thus make it possible to
Flight again plays a role buffer spring in rotation process；So that the elastic strength of buffer spring becomes larger；It is so of the invention
Middle return cylinder is installed on the 4th shaft upper end；Fixture block is installed on the periphery of return cylinder；Spring installation shaft is installed on
On the upside of fixture block；Spring is installed and is provided with resetting spring between shaft and piston；Limited block is installed on the downside of upper piston plate；Limit
Position block coordinates with fixture block；It can be contacted in the present invention after fixture block rotates 180 degree with limited block.Spring installation shaft can be relative to
Fixture block rotates.In the 4th shaft rotation process；4th shaft can drive return cylinder to rotate；Return cylinder, which rotates, drives fixture block
Rotate；Fixture block, which rotates, drives spring installation shaft to rotate；Spring installation shaft, which rotates, will stretch resetting spring；In the 4th shaft
Drive in flight rotation process；When event resolves of the flight to buffer spring；Limited block is also just moved to and fixture block
On the position of sustained height；Fixture block is also just rotated on the position contacted with limited block at the same time；I.e. limited block plays fixture block
Position-limiting action；Prevent flight is rotated further from again serving to effect to buffer spring；After the completion of damping, limited block is in upper piston
Returned under the drive of plate on original position；And fixture block will be turned on original position under the action of resetting spring.
High-pressure helium is full of by can inherently be risen to push rod in the space of upper piston plate and lower piston plate both sides in the present invention
To the effect of damping.
During the damping that people are designed using the present invention；When upper backup pad is hit；Upper backup pad will be pressed
Contracting, moves down；Upper backup pad moves down will compression shock absorption spring；The effect of damping is played by damping spring；At the same time
Lower supporting plate, which moves down, to drive push rod to move down；Push rod, which moves down, drives upper piston plate to move down；Upper piston
Plate moves down will Compression and Expansion spring；At the same time upper piston plate move down will by buffer spring drive lower piston plate to
Lower movement；High-pressure helium during lower piston plate moves down between lower piston plate and corresponding piston shell will pass through piston
Air outlet pipe and motor air inlets flow are in air motor；The gas flowed into air motor will cause air motor to work；
Even if the motor shaft obtained on air motor rotates；Motor shaft, which rotates, drives generator input shaft to rotate；I.e. so that generator
Power generation；And the gas in air motor can be finally flowed into lower piston plate and piston shell by motor gas outlet and piston intake pipe
In the space of downside；Since the volume flowed in and out of gas in piston shell is identical in the present invention；But upper piston plate is with
Together in moving process, the length being moved on the inside of piston shell is continuously increased piston plate；That is upper piston plate and lower piston plate exists
During moving together；Upper piston plate and the volume in upside space in piston shell and lower piston plate and piston shell inner underside space
Volume differences continue to increase；So flowing into lower piston plate and the excessive gas in the space of piston shell inner underside at this time will extrude
Piston plate；So that upper piston plate is moved down relative to lower piston plate；Upper piston plate move down will drive triggering rack to
Lower movement；Triggering rack, which moves down, will drive the 4th gear to rotate；4th gear, which rotates, drives the second shaft to rotate；Second
Shaft, which rotates, drives unidirectional ring to rotate；Unidirectional ring, which rotates, drives first gear to rotate；First gear, which rotates, drives second gear to turn
It is dynamic；Due to second gear by thread fitting be installed on the 3rd threaded rod on, one end of the 3rd threaded rod is installed on lower piston plate
On；So second gear can also be moved up along the 3rd threaded rod while second gear rotates；Second gear rotates just
It can be rotated by the teeth teeth installation wheel of stirring in second gear；Teeth installation wheel, which rotates, drives the 4th shaft to rotate；
4th shaft, which rotates, drives flight to rotate；Flight, which rotates, will compress buffer spring；So that buffer spring and flight
Contact point constantly moves up；The elastic strength of the buffer spring to work i.e. on buffer spring to upper piston plate constantly becomes larger；
The buffer spring that upper piston plate works just is become to be not easy to be compressed i.e. on buffer spring；I.e. upper piston plate was moving down
Cheng Zhong；The resistance that upper piston plate is subject to continues to increase；When i.e. push rod is hit, catch bar shakes under the action of buffer spring
Amplitude diminishes；So as to have the function that buffering；Prevent that push rod amplitude is larger and damages overall because when push rod is subject to larger shock
