It is all protected by Patent Law in scope of the presently claimed invention.
Embodiment 1, as shown in Fig. 1,2,3,4,5, a kind of forward and reverse balanced limitation self-return regulating mechanism, including be in straight
The transmission shaft 1 set and the pull rod 2 positioned at 1 side of the transmission shaft are erected, is fixed on the transmission shaft 1 described in driving clockwise
Pull rod 2 rotate clockwise in tiling shape driving plate clockwise 3 and drive that the pull rod 2 rotates counterclockwise counterclockwise in putting down
The driving plate counterclockwise 4 of shape is spread, is provided with and the driving plate 3 clockwise close to the side of the transmission shaft 1 on the pull rod 2
The linkage mechanism clockwise 7 of linkage and the linkage mechanism counterclockwise 8 to link with the driving plate 4 counterclockwise, the transmission shaft 1
On be additionally provided with the elastic recoil mechanism of the return after rotation for pull rod 2.
In said program, transmission shaft 1 is connected to external hydraulic regulator, drives transmission shaft 1 to rotate by rotation, passes
The rotation of moving axis 1 will drive driving plate 3 and driving plate counterclockwise 4 clockwise to rotate together, and original state is that transmission shaft 1 stops
Rotation, and elastic recoil mechanism is in the reset condition of nonelastic effect, when transmission shaft 1 is driven clockwise by external adjustment mechanism
When rotation, driving plate 3 clockwise plays a role, and drives pull rod 2 also to rotate clockwise together by linkage mechanism 7 clockwise, real
Existing pull rod carries out hydraulic control, and transmission shaft 1 rotates so that elastic recoil mechanism forms elastic reactance, when external adjusting machine
Structure stops driving, and transmission shaft 1 loses external driving force, then can be under the elastic reactance of elastic recoil mechanism, transmission shaft 1
Simultaneously return is rotated counterclockwise, the process of return is to play a role by driving plate 4 counterclockwise, and pass through linkage mechanism 8 counterclockwise
It drives pull rod 2 also to rotate counterclockwise together, eventually passes back to original position, and when transmission shaft 1 is turned counterclockwise by external adjustment mechanism driving
When dynamic, entire hydraulic control and return process just drive the process that transmission shaft 1 rotates clockwise with said external regulating mechanism
On the contrary, being first to be played a role to carry out hydraulic control by driving plate 4 counterclockwise, return process is played by driving plate 3 clockwise
Effect can be achieved with forward and reverse hydraulic pressure equilibrium limitation and the self-return after losing adjusting in this way.It is however noted that
When driving plate 3 clockwise and linkage mechanism clockwise 7 are driven, driving plate 4 counterclockwise and linkage mechanism counterclockwise 8 are answered
It can assist to follow movement with merging, so that driving plate 3 and linkage mechanism clockwise 7 complete clockwise rotation process clockwise
And one is formed perfectly without transition state, because once rotating counterclockwise process it is necessary to driving plate 4 counterclockwise and joining counterclockwise

To the both sides for the extending direction for extending and being overlapped on respectively in the initial state the intermediate extension 52, the top end 61
Be additionally provided between lower part end 62 with the intermediate extension 52 the opposite static limiting plate 612 of vertical direction and it is described on
Portion end 61 and lower part end 62 are also overlapped on the static limiting plate 612 in the intermediate extension respectively in the initial state
The both sides of 52 extending direction.Further, the static limiting plate 612 is located at the top of the intermediate extension 52；Initially
Under state, the top end 61 and lower part end 62 staggeredly extend, and the top end 61 is overlapped on the intermediate extension
52 and wherein homonymy of the static limiting plate 612 in the both sides of the extending direction of the intermediate extension 52, the lower part
End 62 be overlapped on the intermediate extension 52 and the static limiting plate 612 the intermediate extension 52 extending direction
Wherein another homonymy in both sides.The both sides of the extending direction of the intermediate extension 52 namely the extension side of intermediate extension 52
To this direction vector or so both sides two side positions, static limiting plate 612 is to maintain quiet in whole work process
Only fixed state, so when transmission shaft 1 rotates, mounting plate 5 rotates, and intermediate extension 52 can also rotate, no
Pipe is to rotate clockwise or counterclockwise, can all make the wherein side of intermediate extension 52 that can deviate 612 center of static limiting plate, and
The other side can be close to 612 center of static limiting plate, if intermediate extension 52 deviates 612 center side of static limiting plate, overlapped
Top end 61, then can the distance between lower part end 62 widens with overlapped for the other side because top end 61 can be with
Intermediate extension 52 deviates and overlapped for the other side that lower part end 62 still can be overlapped by fixed static limiting plate 612
And offset is not will produce, so can make return spring 6 that can further deform upon and generate elastic reactance for return
It is used, and normally initial initial tension of spring when top end 61 and lower part end 62 are 6 zero-bit of return spring when original state
Intermediate extension 52 and static limiting plate 612 are overlapped in the both sides of the extending direction of the intermediate extension 52.Similarly, if
It is also the same that it is lower part end 62 that intermediate extension 52, which deviates 612 center side of static limiting plate overlapped,.This application involves
Integrally connected mode may be used the techniques such as integrated molding, integrally casting realization.

It can be rolled on two axis 82.The setting can realize that driving effect passes through it when driving plate 3 clockwise rotates clockwise well
Peripheral surface and coupled wheel 71 clockwise are against being driven, so the center with 1 axle center of transmission shaft of coupled wheel 71 clockwise
Between displacement and 3 peripheral surface position of driving plate clockwise and 1 axle center of transmission shaft apart from directly related, as long as driving plate clockwise
As soon as 3 peripheral surface is not a constant with 1 axle center of transmission shaft distance, then having displacement difference so that in coupled wheel 71 clockwise
Heart generation position changes, and will make pull rod 2 that change in location occur, then pull rod 2 can be sent out under the axis support of rotary shaft 201
Raw rotation, as long as so coupled wheel 71 forms the clockwise displacement increase centered on rotary shaft 201, energy clockwise
Pull rod 2 is driven to rotate clockwise, and the anticlockwise displacement that coupled wheel 81 is formed centered on rotary shaft 201 counterclockwise increases
Add, pull rod 2 can be driven to rotate counterclockwise, of course for better operating, further design should be structure, when connection clockwise
When the clockwise displacement that driving wheel 71 is formed centered on rotary shaft 201 increases the drive rotation of pull rod 2, join counterclockwise
Driving wheel 81 should be also centered on by rotary shaft 201 clockwise displacement be combined with and follow corresponding increase, and work as the inverse time
When the anticlockwise displacement that needle coupled wheel 81 is formed centered on rotary shaft 201 increases the drive rotation of pull rod 2, up time
Needle coupled wheel 71 should be also centered on by rotary shaft 201 anticlockwise displacement be combined with and follow corresponding increase, in this way
It could be such that regardless of being that driving plate 3 clockwise drives coupled wheel 71 clockwise come when driving pull rod 2 to rotate clockwise, still
Driving plate 4 counterclockwise drives coupled wheel 81 counterclockwise come when driving pull rod 2 to rotate counterclockwise, coupled wheel 71 clockwise and inverse
Hour hands coupled wheel 81 can synchronization marching, while again so that respectively with driving plate 3 clockwise and driving plate counterclockwise 4 phase always
Against this design for allowing for the peripheral surface of driving plate 3 and driving plate counterclockwise 4 clockwise needs an extraordinary size and sets
Meter ensures the seamless connection for driving and driving counterclockwise clockwise.
