Wheel is meshed, and third gear is limited.
User is in order to can guarantee that sucker can be disposably adsorbed onto on the wall surface of ceramic tile, and user is by the dirt of ceramic tile upper wall surface
Dirt or dust are wiped clean, and one layer of water is smeared on wall surface, and the wall surface on ceramic tile is made to have better seal effect.When making
After user squeezes out the air in sucker, on sucker suction to wall surface, a certain amount of water can be adsorbed in sucker；It is arrived in sucker suction
During wall surface, sucker drives shell to be moved to wall direction, and friction pulley squeezes wall surface, then in wall surface to the anti-of friction pulley
Friction pulley is moved to housing direction under active force；Friction pulley drives fixed block to be moved to housing direction through first axle, and first is flexible
Bar is compressed, and telescopic rod spring is compressed；Fixed block is moved through support plate and the second axis band dynamic bevel gear to first gear direction；When
After bevel gear is meshed with the cone tooth in first gear, bevel gear is limited, and then the second axis, support plate, fixed plate, cone tooth group
It closes, first axle and friction pulley are moved without normal direction first gear direction.Then, user can hang over weight on hook.
Sucker generally can all be stained with water and be then affixed on wall in use, to increase adsorption capacity, but dilutional hyponatremia sometimes
When adsorption capacity weaken instead.After hanging weight for the sucker of dilutional hyponatremia, when the weight of weight is more than the suction with more water at this time
When disk adhesive force, sucker is moved down by the gravity of weight along wall surface；When sucker is moved down along wall surface, friction pulley
Counter-rotating, friction pulley are rotated through first axle, the combination of cone tooth and the second axis band dynamic bevel gear, and bevel gear is through first gear, second
Gear and third axis drive the external screw thread rotation on third axis；Internal thread is matched with external screw thread on third axis by screw thread on ring set
Under conjunction, internal thread is moved axially to the direction far from second gear, and then ring set is moved axially to the direction far from second gear,
Turning wheel follows ring set to be moved to the direction far from second gear；When internal thread moves axially to extreme position, external screw thread position
In internal thread close to one end of second gear, and external screw thread and internal thread are locked under screw-thread fit；Turning wheel moves at this time
To the position where rack, plectrum has reached the condition that can stir rack；Then, third axis can be through external screw thread, interior spiral shell
Line and ring set drive turning wheel to rotate in the forward direction, and the direction of rotation of turning wheel is opposite with the direction of rotation of friction pulley.In plectrum
It stirs down, rack smoothly moves up, and damping telescopic bar is compressed, and guide rod moves up in guide rail.This hour rack is no longer
To third gear position limiting, and then the 4th axis is no longer limited；So weight under the effect of gravity, the steel wire being wrapped on winding wheel
Rope is released, and winding wheel generates rotation, and winding wheel drives the 4th axis and the rotation of third gear, the second scroll spring to be compressed.
In the moment of steel wire rope release, the second scroll spring is in uncompressed state, and weight is only by its own gravity at this time
Itself；During weight falls downwards, steel wire rope is gradually discharged, and the second scroll spring is gradually compressed, and with steel
Cord discharges more and more, and the second scroll spring is also just increasingly difficult to be compressed；It is gradually compressed in the second scroll spring
In the process, steel wire rope pulls the power of weight also increasing.When the water in sucker is reduced to a certain extent, the adsorption capacity of sucker
Weight gravity is will be greater than, is also generally higher than gravity in the second scroll spring of synchronization pulling force substantially, the speed of weight tenesmus later
Degree can be slower and slower, and sucker will not pull down wall surface by weight, during the speed of weight tenesmus can be slower and slower, steel wire
Rope is still being released, and the second scroll spring still continues to be compressed, then pulling force also can be increasing, until under weight stopping
Pendant.Glide moving down speed and stroke between stopping are slipped down to since sucker to be determined by the pulling force of steel wire rope, are moved down in sucker
During adhesive force increase, the speed of the weight moved down increases, and the pulling force that weight is transmitted to sucker by steel wire rope is drawn less than weight
Power, which guarantee suckers in the case where the downward pulling force that adhesive force increase is subject in the process is smaller, sucker slide downward
Displacement is smaller；Compared to hinge for the case where weight directly connect with sucker and sucker is made to glide, sucker of the invention is from downslide
To gliding, the glided displacement of stopping is smaller, and the possibility that metope is detached from the gap of two ceramic tiles is slipped down to this reduces sucker
Property, and it is provided with the function of protection weight.The weight of different weights determines the stroke that sucker glides, and the bigger stroke of weight is more
Greatly, the possibility to fall off is bigger, so the present invention only has the function of protection to certain weight object.The present invention can be protected
In the weight implementation process of shield, sucker does not slip down to after gliding at the gap of two ceramic tiles.After sucker stops gliding,
Friction pulley no longer rotates, and then causes second gear that third axis is no longer driven to rotate, and the external screw thread on third axis also no longer rotates；
So under the reset response of the first scroll spring, ring set continue that internal thread and turning wheel is driven to continue on before rotation side
To rotation；So on ring set on internal thread and third axis under externally threaded cooperation, ring set drives turning wheel to second gear
Direction moves axially, until ring set and turning wheel are restored to home position.During turning wheel is restored to home position, dial
Plectrum on driving wheel can be detached from stirs cooperation with rack, then the double action of the reset in rack gravity and damping telescopic bar
Under, rack can be engaged with the generation of third gear again, and third gear is limited again.The limit of third gear cause the 4th axis and
Winding wheel no longer rotates, and then steel wire rope is no longer released, and weight will not fall on the ground and damage.The present invention designs
When preventing weight to haul sucker to continue along hydraulically smooth surface and be moved down at the gap of two ceramic tiles, the sealing of sucker is beaten
It is broken, and then sucker can not be adsorbed on wall surface, the disengaging of sucker cause weight tenesmus to ground and caused by damage.In addition it hangs
Mechanism can be designed so that weight during tenesmus so that the second scroll spring is increasingly difficult to compress, so that outstanding
The pulling force of suspension mechanism is increasing, until weight can stop dropping than faster, avoids weight and continues high speed and drop to ground
Upper caused physical damage, protects the integrality of weight.
After user removes weight, user can take down sucker, then press and stir friction pulley, friction pulley
So that rack moves again up after a series of transmissions, and then rack is no longer to third gear position limiting, then in the second whirlpool
Under the reset response of coil spring, winding wheel can rewind the steel wire rope being released.
Relative to traditional sucker technology, the sucker in the present invention is under weight gravity along wall surface slide downward
In the process, a series of friction wheel from rotation and friction pulley is after transmissions, turning wheel can stir rack by plectrum and move up,
And then rack, no longer to third gear position limiting, weight can drop under the effect of gravity；During weight drops, steel wire rope
Be released, and then the second scroll spring is compressed, with steel wire rope release it is more and more, the second scroll spring is increasingly difficult to press
Contracting, steel wire rope pull the power of weight also increasing, and after pulling force is more than gravity, the lapse rate of weight is gradually slack-off, directly
It drops to stopping.The design of the present invention avoids the physical damage caused by weight continues in high speed tenesmus to ground, protection weight
The integrality of object.The configuration of the present invention is simple has preferable practical function.

User is in order to can guarantee that sucker 1 can be disposably adsorbed onto on the wall surface of ceramic tile, and user is by ceramic tile upper wall surface
Dirt or dust are wiped clean, and one layer of water is smeared on wall surface, and the wall surface on ceramic tile is made to have better seal effect.When
After user squeezes out the air in sucker 1, sucker 1 is adsorbed onto on wall surface, and a certain amount of water can be adsorbed in sucker 1；In sucker 1
During being adsorbed onto wall surface, sucker 1 drives shell 2 to be moved to wall direction, and friction pulley 4 squeezes wall surface, then being given in wall surface
Friction pulley 4 is moved to 2 direction of shell under the reaction force of friction pulley 4；Friction pulley 4 drives fixed block 8 to shell 2 through first axle 7
Direction is moved, and the first telescopic rod 5 is compressed, and telescopic rod spring 6 is compressed；Fixed block 8 is through support plate 10 and the second axis 12 with mantle
Gear 13 is moved to 15 direction of first gear；After bevel gear 13 is meshed with the cone tooth 19 in first gear 15, bevel gear 13
It is limited, and then the second axis 12, support plate 10, fixed plate 41, cone tooth combination 9, first axle 7 and friction pulley 4 are without the first tooth of normal direction
Take turns the movement of 15 directions.Then, user can hang over weight on hook 3.
Sucker 1 generally can all be stained with water and be then affixed on wall in use, to increase adsorption capacity, but dilutional hyponatremia sometimes
When adsorption capacity weaken instead.After hanging weight for the sucker 1 of dilutional hyponatremia, when the weight of weight is more than the suction with more water at this time
When 1 adhesive force of disk, sucker 1 is moved down by the gravity of weight along wall surface；When sucker 1 is moved down along wall surface, rub
4 counter-rotatings of wheel are wiped, friction pulley 4 is rotated through first axle 7, the combination 9 of cone tooth and the second axis 12 with dynamic bevel gear 13, and bevel gear 13 passes through
First gear 15, second gear 16 and third axis 24 drive the external screw thread 27 on third axis 24 to rotate；The internal thread on ring set 17
28 with external screw thread 27 on third axis 24 by under screw-thread fit, internal thread 28 is moved axially to the direction far from second gear 16,
And then ring set 17 is moved axially to the direction far from second gear 16, turning wheel 18 follows ring set 17 to far from second gear 16
It moves in direction；When internal thread 28 moves axially to extreme position, external screw thread 27 is located at internal thread 28 close to second gear 16
One end, and external screw thread 27 and internal thread 28 are locked under screw-thread fit；Turning wheel 18 is moved to the position where rack 36 at this time
It sets, plectrum 29 has reached the condition that can stir rack 36；Then, third axis 24 can be through external screw thread 27,28 and of internal thread
Ring set 17 drives turning wheel 18 to rotate in the forward direction, and the direction of rotation of turning wheel 18 is opposite with the direction of rotation of friction pulley 4.In plectrum
Under 29 stirring, rack 36 smoothly moves up, and damping telescopic bar 40 is compressed, and guide rod 37 moves up in guide rail 38.
This hour rack 36 no longer limits third gear 33, and then the 4th axis 32 is no longer limited；So weight under the effect of gravity, twines
The steel wire rope 39 being wound on winding wheel 34 is released, and winding wheel 34 generates rotation, and winding wheel 34 drives the 4th axis 32 and third tooth
33 rotation of wheel, the second scroll spring 31 are compressed.
In the moment that steel wire rope 39 discharges, the second scroll spring 31 is in uncompressed state, and weight is only by itself at this time
Gravity itself；During weight falls downwards, steel wire rope 39 is gradually discharged, and the second scroll spring 31 is gradually compressed,
And with steel wire rope 39 discharge it is more and more, the second scroll spring 31 is also just increasingly difficult to be compressed；In the second scroll spring
During 31 are gradually compressed, steel wire rope 39 pulls the power of weight also increasing.When the water in sucker 1 is reduced to certain journey
When spending, the adsorption capacity of sucker 1 will be greater than weight gravity, substantially also generally higher than heavy in 31 pulling force of the second scroll spring of synchronization
The speed of power, later weight tenesmus can be slower and slower, and sucker 1 will not pull down wall surface by weight, in the speed meeting of weight tenesmus
In slower and slower process, steel wire rope 39 is still being released, and the second scroll spring 31 still continues to be compressed, then pulling force
Can be increasing, until weight stops dropping.It is slipped down to since sucker 1 and moves down speed and stroke by steel between gliding stopping
The pulling force of cord 39 determines, during sucker 1 moves down adhesive force increase, the speed of the weight moved down increases, and weight passes through steel
Cord 39 be transmitted to sucker 1 pulling force be less than weight pulling force, which guarantee suckers 1 be subject in the process in adhesive force increase it is downward
In the case that pulling force is smaller, the displacement of 1 slide downward of sucker is smaller；It is directly connect with sucker 1 in weight compared to hinge and makes sucker 1
For the case where downslide, the glided displacement of downslide stopping is smaller, and this reduces suckers 1 from slipping down to for sucker 1 of the invention
The possibility for being detached from metope at the gap of two ceramic tiles is slipped down to, and is provided with the function of protection weight.The weight of different weights
Determine the stroke that sucker 1 glides, weight is bigger, and stroke is bigger, and the possibility to fall off is bigger, so the present invention is only to certain weight
Amount object has the function of protection.In the weight implementation process that can be protected for the present invention, sucker 1 glides later there is no under
It slides at the gap of two ceramic tiles.After sucker 1 stops gliding, friction pulley 4 no longer rotates, and then leads to second gear 16 no longer
