10 is corresponding and be mutually adapted, and fixed ratchet 9 can be made using the shape pressure of itself during movable frame 1 moves downward
Compel activity ratchet 10, behind fixed ratchet 9 higher movable ratchet 10, movable ratchet 10 can limit the position of fixed ratchet 9, make it
Can not be moved right under meshing state, i.e., at this time movable frame 1 can free movement to the left, using the principle of ratchet, under can making
Fixed fixture block 4, active fastening block 13 and upper fixed fixture block 17 maintain certain height, play the barrier effect to vehicle.
During movable frame 1 moves downward, using two follower levers 12 push two active fastening blocks 13 make to
Unlucky dynamic, i.e., the distance between two active fastening blocks 13 increase at this time, and Chinese herbaceous peony wheel can pass through two active fastening blocks 13, at this time
Back wheels of vehicle is detached from from lower fixed block 4, and lower fixed block 4 is restored to original position under the elastic deformation effect for forcing retracting spring 5
It sets and highly, two rear wheels is blocked, while driving movable frames 1 to move right by two driving levers 3, two can be driven
Active fastening block 13, which performs relative motion, is restored to original position, and two Chinese herbaceous peony wheels are blocked.
Above structure and process please refer to Fig. 1-4.
Make when needing to drive, vehicle is started to a bit to the left is pressed in its front-wheel on upper fixed fixture block 17, at this time due to four
A activity ratchet 10 is hinged by hinge bar with upper fixed fixture block 17 respectively, i.e., upper at this time fixed fixture block 17 is moved downward and can be driven
Movable ratchet 10 rotates, i.e., movable ratchet 10 and fixed ratchet 9 are disengaged from state at this time, meanwhile, it is transported in upper fixed fixture block 17
In dynamic process, two active fastening blocks 13 are pushed to support or oppose movement using connecting rod 16, i.e., at this time between two active fastening blocks 13
Distance increase, meanwhile, can be driven by the movement of two active fastening blocks 13 fixed under movable frame 1 and two fixture block 4 movement,
Fixture block 4 is fixed under i.e. at this time two move downwardly to and flush with ground, vehicle can be outputed at this time.
Above structure and process please refer to Fig. 5-8.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
