Third square type cylinder in the present invention, the first rack gear, the first connecting plate, the second square type cylinder, the first guide block, the first spring, The design of second guide block, second spring, flexible inner panel and friction plate is: first, when first gear and corresponding first rack gear When one end far from the first connecting plate is meshed, the location of third square type cylinder is defined, and second spring is in compressive state, First spring is in tensional state, and friction plate and ground touch；Since second spring is in compressive state and third square type cylinder Location is defined, then flexible inner panel and friction plate will receive downward pressure, the friction of such friction plate and ground Power will substantially increase.Second, after the limitation that first gear rotates clockwise is released from, under the reset response of the first spring, Third square type cylinder drives the first guide block mobile to the cylinder bottom of the second square type cylinder in terms of, and third square type cylinder is through the first connecting plate drive the One rack gear is mobile in terms of the cylinder bottom of the second square type cylinder, and the first rack drives first gear rotates counterclockwise；In second spring Under reset response, it also can help to third square type cylinder and drive the first guide block mobile in terms of the cylinder bottom of the second square type cylinder；When second After spring reset to nature, there is flexible inner panel one end of the second guide block to be moved to the bottom of the second guide groove, rub at this time Contact condition is still between wiping board and ground, only the pressure between friction plate and ground is substantially zeroed, and at this moment first Spring is still in reset state；Then, under the action of the first spring continues reset, third square type cylinder, the first guide block, first Connecting plate and the first rack gear continue the movement in terms of the cylinder bottom of the second square type cylinder, and third square type cylinder is through the second guide block and flexible inner panel Drive friction plate mobile in terms of the cylinder bottom of the second square type cylinder, friction plate is detached from the contact with ground.Third, when the first spring After reset energy consumption is complete, in the raw, there is flexible inner panel second spring one end of the second guide block to be located at the second guide groove Bottom, there are spacing between friction plate and ground, the first rack gear is still in meshing state with first gear.

The first rack gear, first gear, second gear in the present invention and the relationship between bar shaped tooth plate need to meet: setting Under the reset response of the first spring, when the first rack gear is mobile to the second square type cylinder cylinder bottom direction, the first rack gear makes first gear The circle number rotated clockwise is n1；It is set under the reset response of pulling plate spring, bar shaped tooth plate is moved to the direction of the first square type cylinder When dynamic, circle number n2 that bar shaped tooth plate rotates second gear counterclockwise；So n1 is more than or equal to n2, just can guarantee in this way In second gear rotates counterclockwise, second gear drives first gear to rotate counterclockwise through first rotating shaft, so that first gear The first rack gear can be made to be moved to home position to the direction of friction plate, that is, the one end of the first rack gear far from the first connecting plate The position that teeth are meshed with first gear.

The second rack gear and third gear in the present invention need to meet: mobile to the direction of the second square type cylinder in friction plate When, third gear is in meshing state with the second rack gear always.

Second rack gear, third gear, the second shaft, winding wheel, the second fixed plate, wirerope, wobble plate, friction in the present invention The design of plate and leaf spring is: first, when friction plate and ground touching, wobble plate is conllinear with friction plate, and leaf spring is in compression State.Second, when friction plate is mobile to the direction of the second square type cylinder, friction plate drives the through the second fixed plate, the second shaft Three gears and winding wheel are mobile to the direction of the second square type cylinder, and since third gear is meshed with the second rack gear, third gear is suitable Hour hands rotation, third gear drive winding wheel to rotate clockwise through the second shaft, and wirerope is wound and wirerope pulls wobble plate, Wobble plate is swung along the direction of lineoutofservice signal pull, and leaf spring continuation is compressed；After friction plate stops movement, third gear up time Needle 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. Third, when friction plate into the direction moving process far from the second square type cylinder, friction plate drives through the second fixed plate, the second shaft Third gear and winding wheel are 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 answering for leaf spring Under the effect of position, wobble plate is swung to the bottom surface of friction plate, and wirerope is in the state tensed；After friction plate and ground face contact, this When wobble plate just swing to the position mutually conllinear with friction plate.

The design of flexible inner panel, fixing axle and bar shaped sliding slot is in the present invention: in the process that flexible inner panel moves up and down In, bar shaped sliding slot can make fixing axle relatively slide in flexible inner panel, smoothly move up and down to meet flexible inner panel.

In the present invention design of the second guide block be in order to prevent flexible inner panel during moving up and down from the second square type It is detached from cylinder.The design of first guide block is that the second square type cylinder takes off from third square type cylinder during moving up and down in order to prevent From.

Casing in the present invention is provided with computer electronic hardware.

After mainframe box of the invention is static is placed on suitable operating position, pulling plate spring is not stretched at this time, bar shaped Two groups of items do not stir cooperation by group item generation with corresponding on pulling plate；When telescopic strap spring is uncompressed, limit telescopic item One end with fillet is inserted into the corresponding limiting slot of stop collar.Friction plate and ground phase CONTACT WITH FRICTION, first gear and phase The first rack gear answered is meshed far from one end of the first connecting plate, and second spring is in compressive state, and the first spring, which is in, to be stretched State, stretch at this time inner panel and friction plate will receive downward pressure, and the frictional force on such friction plate and ground will substantially increase, Such design is just avoided that mainframe box can be generated bigger displacement by after the bigger outer power of kicking, and then avoids mainframe box Power supply line be detached from from socket and cause mainframe box instant cut-off, the data finally avoided inside computer will not be disconnected because of moment Loss caused by electricity.When friction plate and ground touch, wobble plate is conllinear with friction plate, and leaf spring is in compressive state, then putting 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.

Second rack gear 45, third gear 50, the second shaft 58, winding wheel 49, the second fixed plate 41, wirerope in the present invention 47, the design of wobble plate 43, friction plate 42 and leaf spring 48 is: first, when friction plate 42 and ground touch, wobble plate 43 with rub Wiping board 42 is conllinear, and leaf spring 48 is in compressive state.Second, when friction plate 42 is mobile to the direction of the second square type cylinder 37, friction Plate 42 drives third gear 50 and winding wheel 49 to move to the direction of the second square type cylinder 37 through the second fixed plate 41, the second shaft 58 Dynamic, since third gear 50 is meshed with the second rack gear 45, as shown in figure 22, third gear 50 is rotated clockwise, third gear 50 drive winding wheel 49 to rotate clockwise through the second shaft 58, and wirerope 47 is wound and wirerope 47 pulls wobble plate 43, wobble plate 43 swing along the direction of 47 pulling force of wirerope, and the continuation of leaf spring 48 is compressed；After friction plate 42 stops movement, third gear 50 rotate clockwise end；Wobble plate 43 is higher than the position of friction plate 42, that is, wobble plate 43 far from one end of friction plate 42 at this time State in tilting.Third, when friction plate 42 into the direction moving process far from the second square type cylinder 37, friction plate 42 is through the Two fixed plates 41, the second shaft 58 drive third gear 50 and winding wheel 49 mobile to the direction far from the second square type cylinder 37, by It is meshed in third gear 50 with the second rack gear 45, as shown in figure 22, third gear 50 rotates counterclockwise, and third gear 50 is through the Two shafts 58 drive winding wheel 49 to rotate counterclockwise, and wirerope 47 is released, and under the reset response of leaf spring 48, wobble plate 43 is to rubbing The bottom surface of wiping board 42 is swung, and wirerope 47 is in the state tensed；After friction plate 42 and ground face contact, wobble plate 43 is just at this time Swing to the position mutually conllinear with friction plate 42.

The design of flexible inner panel 51, fixing axle 22 and bar shaped sliding slot 57 is in the present invention: moving down on flexible inner panel 51 In dynamic process, bar shaped sliding slot 57 can make fixing axle 22 relatively slide in flexible inner panel 51, to meet flexible inner panel 51 smoothly move up and down.

In the present invention design of the second guide block 52 be in order to prevent flexible inner panel 51 during moving up and down from second It is detached from square type cylinder 37.The design of first guide block 44 be in order to prevent the second square type cylinder 37 during moving up and down from third It is detached from square type cylinder 38.

Casing 3 in the present invention is provided with computer electronic hardware.

Specific embodiment: after mainframe box of the invention is static is placed on suitable operating position, pulling plate spring at this time 24 are not stretched, and two groups of items 25 do not stir cooperation by group generation of item 31 with corresponding on bar shaped pulling plate 5；Telescopic strap spring 35 When being uncompressed, there is limit telescopic item 32 one end of fillet 36 to be inserted into the corresponding limiting slot 33 of stop collar 15.Friction plate 42 are meshed with corresponding first rack gear 39 far from one end of the first connecting plate 40 with ground phase CONTACT WITH FRICTION, first gear 14, Second spring 54 is in compressive state, and the first spring 56 is in tensional state, and flexible inner panel 51 and friction plate 42 will receive at this time Downward pressure, such friction plate 42 and the frictional force on ground will substantially increase, it is such design be just avoided that mainframe box by Bigger displacement can be generated after the bigger outer power of kicking, and then avoids the power supply line of mainframe box from being detached from from socket and causes host Case instant cut-off, the data finally avoided inside computer will not be because of the loss caused by instant cut-off.Friction plate 42 and ground When face is in contact, wobble plate 43 and friction plate 42 are conllinear, and leaf spring 48 is in compressive state, rub then wobble plate 43 can also be generated with ground Contact is wiped, can also expand the friction effect between certain friction plate 42 and ground in this way.

Since there is limit telescopic item 32 one end of fillet 36 to be inserted into the corresponding limiting slot 33 of stop collar 15, limit is stretched Contracting item 32 limits the rotation of stop collar 15, and then the unidirectional outer ring 30 of the second one-way clutch ring 28 is limited, then single second To under the single effect of clutch ring 28, as shown in figure 9, first rotating shaft 18 and first gear 14 can not rotate clockwise, thus The state that first gear 14 can be maintained to be meshed with corresponding first rack gear 39 far from one end of the first connecting plate 40 guarantees friction There is pressure always between plate 42 and ground.

When mainframe box of the invention needs shift position, user drives item through pull rod 6 by pull handle 7, handle 7 Into the direction moving process far from the first square type cylinder 8, pulling plate spring 24 is stretched shape pulling plate 5.Two items on bar shaped pulling plate 5 Shape tooth plate 26 is identical with the effect that the second wheel mechanism 2 generates to first round mechanism 1 respectively with two groups of items 25, with the first round For mechanism 1: when bar shaped pulling plate 5 into the direction moving process far from the first square type cylinder 8, pulling plate spring 24 is stretched, bar shaped Tooth plate 26 drives second gear 19 to rotate clockwise；As shown in figure 9, under the action of the first one-way clutch ring 27, second gear 19 can not drive first rotating shaft 18 to rotate clockwise through the first one-way clutch ring 27.As bar shaped pulling plate 5 continues to far from first The direction of square type cylinder 8 is mobile, and group item 25 can contact with the generation of item 31 is dialled and dial item 25 and stir by group item 31, is dialled item 31 and driven Limit telescopic article 32 is mobile to the direction of the 4th square type cylinder 17, and telescopic strap spring 35 is compressed, and limit telescopic item 32 has fillet 36 one end is detached from from the corresponding limiting slot 33 of stop collar 15；When limit telescopic item 32 has one end of fillet 36 from stop collar After being detached from 15 corresponding limiting slots 33, the end teeth of bar shaped tooth plate 26 are meshed with second gear 19.Limit telescopic item 32 One end with fillet 36 is detached from from the corresponding limiting slot 33 of stop collar 15, and limit telescopic item 32 no longer generates stop collar 15 Position-limiting action, and then the unidirectional outer ring 30 of the second one-way clutch ring 28 is no longer limited, then first rotating shaft 18 and first gear 14 allow to rotate clockwise.

After the limitation that first gear 14 rotates clockwise is released from, under the reset response of the first spring 56, third square Type tube 38 drives the first guide block 44 mobile in terms of the cylinder bottom of the second square type cylinder 37, and third square type cylinder 38 is through 40 band of the first connecting plate Dynamic first rack gear 39 is mobile in terms of the cylinder bottom of the second square type cylinder 37, and as shown in figure 18, the first rack gear 39 drives first gear 14 Rotation counterclockwise；Under the reset response of second spring 54, it also can help to third square type cylinder 38 and drive the first guide block 44 to the It is mobile in terms of the cylinder bottom of two square type cylinders 37；After second spring 54 resets to nature, the inner panel 51 that stretches has the second guide block 52 one end is moved to the bottom of the second guide groove 53, is still in contact condition between friction plate 42 and ground at this time, only Pressure between friction plate 42 and ground is substantially zeroed, and the first spring 56 at this moment is still in reset state；Then, first Under the action of spring 56 continues reset, third square type cylinder 38, the first guide block 44, the first connecting plate 40 and the first rack gear 39 continue to It is mobile in terms of the cylinder bottom of second square type cylinder 37, third square type cylinder 38 through the second guide block 52 and flexible inner panel 51 drive friction plate 42 to Mobile in terms of the cylinder bottom of second square type cylinder 37, friction plate 42 is detached from the contact with ground.When the reset energy of the first spring 56 disappears After having consumed, in the raw, there is flexible inner panel 51 second spring 54 one end of second guide block 52 to be located at the second guide groove 53 Bottom, there are spacing between friction plate 42 and ground, the first rack gear 39 is still in meshing state with first gear 14.When rubbing After wiping board 42 and ground are detached from, mainframe box is no longer influenced by friction limit, and mainframe box only needs the pulling force of very little just can pass through wheel 21 is mobile.Design between friction plate 42 and ground there are spacing is avoided that mainframe box in the process of moving, friction plate 42 with Ground continuous frictional avoids the fretting wear of friction plate 42；Being compared to friction plate 42, there is no between having between ground Away from design for, although friction of the mainframe box when moving between friction plate 42 and ground can be made by some simple designs Power becomes smaller, as long as but frictional force between friction plate 42 and ground when being less than extraneous motive force, mainframe box just can be pulled, this Sample friction plate 42, which is not present between ground, has spacing, so that cabinet increases the fretting wear of friction plate 42 when mobile, subtracts The small service life of friction plate 42.In addition, the design between friction plate 42 and ground there are spacing can also allow that mainframe box very It is easy to be unlikely to by some small barriers because the presence of friction plate 42 move up mainframe box can only on flat ground It is dynamic.

When friction plate 42 is mobile to the direction of the second square type cylinder 37, friction plate 42 is through the second fixed plate 41, the second shaft 58 drive third gear 50 and winding wheel 49 mobile to the direction of the second square type cylinder 37, due to third gear 50 and the second rack gear 45 It is meshed, as shown in figure 22, third gear 50 rotates clockwise, and third gear 50 drives 49 up time of winding wheel through the second shaft 58 Needle rotation, wirerope 47 is wound and wirerope 47 pulls wobble plate 43, and wobble plate 43 is swung along the direction of 47 pulling force of wirerope, plate The continuation of spring 48 is compressed；After friction plate 42 stops movement, third gear 50 rotates clockwise end；Wobble plate 43 is separate at this time One end of friction plate 42 is higher than the position of friction plate 42, that is, wobble plate 43 is in the state tilted.Wobble plate 43 is in tilting 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 Under 24 reset response, bar shaped pulling plate 5 is resetted to the direction of the first square type cylinder 8 is mobile, and bar shaped tooth plate 26 drives second gear 19 It rotates clockwise；As shown in figure 9, second gear 19 is through the first one-way clutch ring 27 under the action of the first one-way clutch ring 27 First rotating shaft 18 and first gear 14 is driven to rotate counterclockwise；It dials item 25 to reset as bar shaped pulling plate 5 is mobile, dials item 25 and no longer dial It is dynamic to be dialled item 31.So under the reset response of telescopic strap spring 35, there is limit telescopic item 32 one end of fillet 36 to insert again Enter into the corresponding limiting slot 33 of stop collar 15.As shown in figure 18, during first gear 14 rotates counterclockwise, the first tooth Wheel 14 drives third square type cylinder 38 to move to the direction far from 37 bottoms of the second square type cylinder through the first rack gear 39 and the first connecting plate 40 Dynamic, the first spring 56 is stretched, and third square type cylinder 38 drives second spring 54, the second guide block 52, flexible inner panel 51 and friction plate 42 is mobile to the direction far from 37 bottoms of the second square type cylinder, and second spring 54 is uncompressed at this time.When friction plate 42 and ground phase After contact, flexible inner panel 51 and friction plate 42 are no longer moved, as first gear 14 is through the first rack gear 39 and the first connecting plate 40 Third square type cylinder 38 is driven to continue to move to the direction far from second 37 bottoms of square type cylinder, the first spring 56 continues to be stretched, the Two springs 54 are compressed；Until first gear 14 toggles it to the first rack gear 39, first gear 14 and corresponding first rack gear 39 The position that one end far from the first connecting plate 40 is meshed；If first gear 14 continues to rotate counterclockwise at this time, first gear 14 can only persistently stir the teeth of the one end of the first rack gear 39 far from the first connecting plate 40, and the first rack gear 39 no longer moves.Most The whole movement of bar shaped pulling plate 5 resets to home position, and pulling plate spring 24 is again at nature.

When friction plate 42 to far from the second square type cylinder 37 direction moving process in, friction plate 42 through the second fixed plate 41, Second shaft 58 drives third gear 50 and winding wheel 49 mobile to the direction far from the second square type cylinder 37, due to third gear 50 It is meshed with the second rack gear 45, as shown in figure 22, third gear 50 rotates counterclockwise, and third gear 50 drives through the second shaft 58 Winding wheel 49 rotates counterclockwise, and wirerope 47 is released, and under the reset response of leaf spring 48, wobble plate 43 is to the bottom surface of friction plate 42 It swings, wirerope 47 is in the state tensed；After friction plate 42 and ground face contact, wobble plate 43 just swings to and rubs at this time The mutually conllinear position of plate 42.

In conclusion main beneficial effect of the invention is: mainframe box of the invention is in static placement, first gear 14 Anticlockwise rotation is limited, and can thus maintain first gear 14 with corresponding first rack gear 39 far from the first connecting plate The state that 40 one end is meshed guarantees there is pressure always between friction plate 42 and ground.Flexible inner panel 51 and friction plate 42 By the design of downward pressure, can make friction plate 42 and the frictional force on ground that will substantially increase, thus avoid mainframe box by Bigger displacement can be generated after the bigger outer power of kicking, and then avoids the power supply line of mainframe box from being detached from from socket and causes host Case instant cut-off.In addition, the design that wobble plate 43 tilts can make mainframe box by some big barriers, expands mainframe box and exist Movement under different road conditions.The configuration of the present invention is simple has preferable using effect.
