Plate also can generate CONTACT WITH FRICTION with ground, can also expand the friction effect between certain friction plate and ground in this way.
Since there is limit telescopic item one end of fillet to be inserted into the corresponding limiting slot of stop collar, the limitation of limit telescopic item
The rotation of stop collar, and then the unidirectional outer ring of the second one-way clutch ring is limited, then in the unidirectional work of the second one-way clutch ring
Under, first rotating shaft and first gear can not be rotated clockwise, and can thus maintain first gear remote with corresponding first rack gear
The state that one end from the first connecting plate is meshed guarantees there is pressure always between friction plate and ground.
When mainframe box of the invention needs shift position, user drives bar shaped by pull handle, hand channel pull rod
Into the direction moving process far from the first square type cylinder, pulling plate spring is stretched pulling plate.Two bar shaped tooth plates on bar shaped pulling plate
It is identical with the effect that the second wheel mechanism generates to first round mechanism respectively with two groups of items, by taking first round mechanism as an example: when
Into the direction moving process far from the first square type cylinder, pulling plate spring is stretched bar shaped pulling plate, and bar shaped tooth plate drives second gear
It rotates clockwise;Under the action of the first one-way clutch ring, second gear can not move first rotating shaft through the first one-way clutch annulus
It rotates clockwise.As bar shaped pulling plate continues to the direction movement far from the first square type cylinder, dialling item can contact with item generation is dialled
And dial item and stir by group item, article drive limit telescopic article is dialled to the movement of the direction of the 4th square type cylinder, telescopic strap spring is compressed,
There is limit telescopic item one end of fillet to be detached from from the corresponding limiting slot of stop collar;When limit telescopic item has one end of fillet
After being detached from the corresponding limiting slot of stop collar, the end teeth of bar shaped tooth plate are meshed with the second gear.Limit telescopic item tool
There is one end of fillet to be detached from from the corresponding limiting slot of stop collar, limit telescopic item no longer generates position-limiting action to stop collar, into
And the unidirectional outer ring of the second one-way clutch ring is no longer limited, then first rotating shaft and first gear allow to rotate clockwise.
After the limitation that first gear rotates clockwise is released from, under the reset response of the first spring, third square type cylinder
Drive the first guide block mobile in terms of the cylinder bottom of the second square type cylinder, third square type cylinder drives the first rack gear to the through the first connecting plate
Mobile in terms of the cylinder bottom of two square type cylinders, the first rack drives first gear rotates counterclockwise;Under the reset response of second spring,
Also can help to third square type cylinder drives the first guide block mobile in terms of the cylinder bottom of the second square type cylinder;When second spring is reset to certainly
After right state, the bottom that there is flexible inner panel one end of the second guide block to be moved to the second guide groove, at this time friction plate and ground it
Between be still in contact condition, only the pressure between friction plate and ground is substantially zeroed, and the first spring at this moment is still in
Reset state;Then, under the action of the first spring continues reset, third square type cylinder, the first guide block, the first connecting plate and first
Rack gear continue in terms of the cylinder bottom of the second square type cylinder it is mobile, third square type cylinder through the second guide block and flexible inner panel drive friction plate to
Mobile in terms of the cylinder bottom of second square type cylinder, friction plate is detached from the contact with ground.After the reset energy consumption of the first spring is complete,
Second spring in the raw, the bottom that there is flexible inner panel one end of the second guide block to be located at the second guide groove, friction plate and
There are spacing between ground, the first rack gear is still in meshing state with first gear.After friction plate and ground are detached from, host
Case is no longer influenced by friction limit, and mainframe box only needs the pulling force of very little just can be mobile by wheel.It is deposited between friction plate and ground
Mainframe box is avoided that in the process of moving in the design of spacing, and friction plate and ground continuous frictional avoid rubbing for friction plate
Scouring damage;It is compared to friction plate to be not present for the design between ground with spacing, although simply setting by some
Meter can make frictional force of the mainframe box when moving between friction plate and ground become smaller, as long as but rubbing between friction plate and ground
When wiping power less than extraneous motive force, mainframe box just can be pulled, and such friction plate, which is not present between ground, has spacing, so that
Cabinet increases the fretting wear of friction plate when mobile, reduce the service life of friction plate.In addition, between friction plate and ground
Mainframe box can also allow that be easy to be unlikely to by some small barriers there are the design of spacing because the presence of friction plate makes
Obtaining mainframe box can only move on flat ground.
When friction plate is mobile to the direction of the second square type cylinder, friction plate drives third through the second fixed plate, the second shaft
Gear and winding wheel are mobile to the direction of the second square type cylinder, since third gear is meshed with the second rack gear, third gear up time
Needle rotation, third gear drive winding wheel to rotate clockwise through the second shaft, and wirerope is wound and wirerope pulls wobble plate, pendulum
Plate is swung along the direction of lineoutofservice signal pull, and leaf spring continuation is compressed;After friction plate stops movement, third gear is clockwise
Rotation terminates;Wobble plate is higher than the position of friction plate far from one end of friction plate at this time, that is, wobble plate is in the state tilted.Pendulum
Plate, which is in the design tilted, facilitates mainframe box by some big barriers, expands shifting of the mainframe box under different road conditions
It is dynamic.When the height of big barrier is greater than between friction plate and ground there are when spacing, the wobble plate that friction front edge of board tilts is first
Big barrier can be touched, due to the presence of leaf spring, big barrier is not easy that wobble plate is made to generate bigger swing;So
Continuing to move along under the guidance of the wobble plate of tilting and with friction plate, big barrier can along wobble plate guidance and enter
To under friction plate, barrier big at this time jacks up friction plate, and such friction plate will not generate mobile limit with big barrier
Position, mainframe box just can continue to be pulled, until friction plate is entirely capable of more excessive barrier.
After mainframe box is reapposed over suitable operating position, user's no longer pull handle, then in pulling plate spring
Reset response under, bar shaped pulling plate is resetted to the direction of the first square type cylinder is mobile, and bar shaped tooth plate drives second gear to revolve clockwise
Turn;Under the action of the first one-way clutch ring, second gear moves first rotating shaft through the first one-way clutch annulus and first gear is inverse
Hour hands rotation;It dials item to reset as bar shaped pulling plate is mobile, dials item and no longer stir by group item.So make in the reset of telescopic strap spring
Under, there is limit telescopic item one end of fillet to be re-inserted into the corresponding limiting slot of stop collar.It is counterclockwise in first gear
During rotation, first gear drives third square type cylinder to far from the second square type cylinder cylinder bottom through the first rack gear and the first connecting plate
Direction it is mobile, the first spring is stretched, third square type cylinder drive second spring, the second guide block, flexible inner panel and friction plate to
Direction far from the second square type cylinder cylinder bottom is mobile, and second spring is uncompressed at this time.When friction plate and ground after touch, stretch
Inner panel and friction plate no longer move, as first gear drives third square type cylinder to far from the through the first rack gear and the first connecting plate
The direction at two square type cylinder cylinder bottoms continues to move to, and the first spring continues to be stretched, and second spring is compressed;Until first gear is by
One rack gear toggles it to, the position that first gear is meshed with corresponding first rack gear far from one end of the first connecting plate;If this
When first gear continue rotation counterclockwise, first gear can only persistently stir the tooth of the one end of the first rack gear far from the first connecting plate
Tooth, and the first rack gear no longer moves.Final bar shaped pulling plate movement resets to home position, and pulling plate spring is again at nature shape
State.
When friction plate into the direction moving process far from the second square type cylinder, friction plate is through the second fixed plate, the second shaft
Drive third gear and winding wheel mobile to the direction far from the second square type cylinder, since third gear is meshed with the second rack gear,
Third gear rotates counterclockwise, and third gear drives winding wheel to rotate counterclockwise through the second shaft, and wirerope is released, in leaf spring
Reset response under, wobble plate to the bottom surface of friction plate swing, wirerope be in tense state;When friction plate and ground face contact
Afterwards, wobble plate just swings to the position mutually conllinear with friction plate at this time.
Relative to traditional cabinet technology, the frictional force that friction plate of the invention and ground generate in design is much larger than latching
Wheel to the frictional force on ground;In static placement, the anticlockwise rotation of first gear is limited mainframe box of the invention
System, the state that can thus maintain first gear to be meshed with corresponding first rack gear far from one end of the first connecting plate guarantee
Always there is pressure between friction plate and ground.The flexible design of inner panel and friction plate by downward pressure, can make friction plate
It will be substantially increased with the frictional force on ground, to avoid mainframe box that from being generated bigger position by after the bigger outer power of kicking
It moves, and then avoids the power supply line of mainframe box from being detached from from socket and cause mainframe box instant cut-off.In addition, the design energy that wobble plate tilts
So that mainframe box expands movement of the mainframe box under different road conditions by some big barriers.The configuration of the present invention is simple, tool
There is preferable using effect.

Design facilitates mainframe box by some big barriers, expands movement of the mainframe box under different road conditions.When big obstacle
The height of object is greater than between friction plate 42 and ground there are when spacing, and the wobble plate 43 that 42 front end of friction plate tilts can touch first
Big barrier, due to the presence of leaf spring 48, big barrier is not easy that wobble plate 43 is made to generate bigger swing;So tilting
Wobble plate 43 guidance under and continuing to move along with friction plate 42, big barrier can along wobble plate 43 guidance and into
Enter under friction plate 42, barrier big at this time jacks up friction plate 42, and such friction plate 42 will not be with big obstacle produce
Raw mobile limit, mainframe box just can continue to be pulled, until friction plate 42 is entirely capable of more excessive barrier.
After mainframe box is reapposed over suitable operating position, user's no longer pull handle 7, then in pulling plate spring
