The utility model not only can be finished the ascending motion of the bar that dries in the air, and the self-locking of bar in uphill process that can also realize drying in the air, its course of work is: handle is engaged turning cylinder 2, turning cylinder 2 moves in the direction of the clock, rotate with turning cylinder 2 reels 21 fixing or one, side wheel 22 or turning cylinder 2 rotate roller 15 are moved towards the big direction in chute 16 spaces, planet carrier 17 breaks away from side wheel 22 or turning cylinder 2, planet carrier 17 is motionless, braking mechanism does not play braking action, thereby reaches the purpose that the bar that dries in the air rises smoothly; When stopping to shake handle, bar, the thing that dries in the air etc. have deadweight owing to dry in the air, reel 21 is (counterclockwise) running in the other direction just, side wheel 22 or turning cylinder 2 rotate roller 15 are moved towards the little direction in chute 16 spaces, planet carrier 17 engages with side wheel 22 or turning cylinder 2, and planet carrier 17 has rotation trend, but because runner 23 is subjected to the effect of frictional force of friction block 5 and transfixion, reel 21 no longer rotates, thereby the bar that dries in the air is motionless.
When need descend the bar that dries in the air automatically, engage with switching shaft 32 after taking off handle, rotate switching shaft 32, stirring of switching shaft 32 33 stirred plate handle 12 or rotating disk 11 (or directly stir plate handle 12 rotating disk 11 is rotated), friction block inclined-plane 9 is opposite with rotating disk inclined-plane 10 directions, cooperatively interact, when rotating disk 11 rotates, rotating disk 11 is owing to the effect of limited cover 29 can not move axially, under the progressive effect on inclined-plane, force friction block 5 to break away from rubbing surface gradually, because the effect of one-way driving mechanism, side wheel 22 rotates with planet carrier 17, planetary gear 19 on the planet carrier 17 drives central gear 20 and rotates, and the planetary wheeling mechanism of this moment is a raising speed mechanism, makes runner 23 high speed rotating, brake member 25 in the cavity 24 is outwards moved by the reason of centrifugal force and forms frictional force with being positioned at its outer brake pot 26 surperficial contacts, and bar at the uniform velocity descends thereby control is dried in the air; When dropping to certain altitude and need lock, the user only need make handle reset, and friction block 5 engages rubbing surface or friction plate gradually under the effect of compression spring 8, thus the self-locking of the bar of realizing drying in the air.In this process,, dry in the air bar bust and hang-up phenomenon have been eliminated owing to the effect reason gradually of release frictional force.In the present embodiment, the brake pot can be an one with housing.
The foregoing description is provided with one-way driving mechanism between reel and raising speed mechanism, guarantee to reel smoothly.If lack this mechanism, then smooth and easy for reel is reeled, braking mechanism performance inoperative, that braking mechanism worked when reel turned round when braking mechanism should have the reel coiling, can but be not limited only to: brake pot is arranged to one-directional rotation, has the one-way driving mechanism that makes brake pot one-directional rotation between the fixture on itself and housing or the housing, when being the reel coiling, the brake pot rotates with brake member, and brake function does not occur; During the reel revolution, and slack, brake function occurs the brake pot owing to one-way driving mechanism.
Thereby another embodiment of the present utility model is:
Embodiment two
In the foregoing description one, planet carrier be fixed in reel one side or with the reel one, it is on the same circumference at center that the planetary gear on the planet carrier evenly is arranged at the turning cylinder axis; Has an one-way driving mechanism between braking mechanism and the housing, be specially: have the one-way driving mechanism that makes brake pot one-directional rotation between the fixture on brake pot and housing or the housing, reel is braked when reeling, and pot can rotate with brake shoes, reel brake pot when revolution is motionless.When reel rotated, because unidirectional transmission, brake shoes rotated with the brake pot, and braking mechanism is inoperative, and when reel turned round, the brake pot was slack under the effect of one-way driving mechanism, and braking mechanism works.
For controlling the many bars that dry in the air respectively, the utility model also can adopt plural hand-operated device to carry out the serial or parallel connection connection.During two hand-operated device parallel connections, two hand-operated devices are arranged side by side, two housings is an one, and switching shaft is between two hand-operated devices, and switching shaft is provided with the head of stirring of directly or indirectly stirring rotating disk respectively, handle can separate with turning cylinder, when need rotate a certain hand-operated device, handle is engaged with this hand-operated device turning cylinder, when bar is dried in the air in need decline, handle is engaged with switching shaft, and the moving corresponding hand-operated device rotating disk of plate gets final product.Like this, just can control a plurality of hand-operated devices respectively.
One-way driving mechanism in the foregoing description can adopt ratchet mechanism or clutch, or other similar structures.
The utility model improves prior art, and the description of related art can be with reference to the description of China Patent No.: ZL03270546.8 and other Hand rocker for clothing-airing rack.
By technique scheme, the utility model can be eliminated the phenomenon of dry in the air bar bust and hang-up, better overcomes the bar that dries in the air owing to the sinking speed that deadweight causes is too fast, safe and reliable.
