Like this; in the time of needs hand hoisting clothes-horse; can tramp with one's feet and expose the treadle outside housing; tooth bar now inwardly rotates and is meshed with driven wheel around the cross bar of upper end on the one hand; the elastic force that overcomes on the other hand wind spring moves down along guide rail, rotates thereby promote driven wheel, and second reel coaxial with driven wheel rotates coiling pull rope thereupon; thereby drive the movable pulley in protection case to move, and then make cool clothing bar increase by first, second halliard.In the time that pin is trampled the lower limit of bar arrival stopper slot and is separated with treadle, ratchet can play the self-locking action to driven wheel, thereby avoid the rollback of the second reel to rotate, be arranged on torsion spring on cross bar and promote tooth bar and outwards rotate and separate with driven wheel, wind spring now pulls cross bar to rise and reset along guide rail together with tooth bar.Repeat above-mentioned action, can make clothes-horse rise to the height needing.And in the time that needs decline clothes-horse, available hand is stirred the ratchet tail end passing outside housing, thereby makes driven wheel release, now clothes-horse can automatically decline under the driving of gravity, and drives driven wheel to rotate backward.Unclamp the tail end of ratchet, ratchet can automatically reset and make driven wheel self-locking, thereby makes clothes-horse drop to the height needing.
For two clothes-horses can synchronously be declined reposefully, so that control its falling head, as shown in Figure 4, in two groups of lifting clothing bar assemblies, walk around and pass the pull rope 71 of controlling housing after the 3rd deflecting roller and can first be connected with one end of a manual coiling rope 75 by a connector 74, then the other end of manual coiling rope connected and be wound on the second reel of manual lifting mechanism.Like this, in the time that the second reel rotates, can make two pull rope synchronization actions by manual coiling rope.In addition, as shown in Figure 6, we also can set firmly a fixed friction wheel 512 near the second reel place in housing, and on fixed friction wheel side, a swing friction pulley 513 is set abreast, swing the lower end that friction pulley is rotatably connected on the swing arm 514 of an inclination, the acclivitous upper end of swing arm is hinged on housing, and housing is being provided with swing arm hinged place the torsion spring that pins swing arm, makes the swing friction pulley of swing arm lower end can rely on all the time fixed friction wheel.In addition, as shown in Figure 7, at fixed friction wheel with swing on the periphery of friction pulley relative semicircle annular groove 515 is set respectively, manual coiling rope just screens at fixed friction wheel with swing between the semicircle annular groove of friction pulley.
When clothes-horse is static, swing arm is subject to the effect of torsion spring, and the swing friction pulley of its lower end is close to fixed friction wheel, thereby pushes down manual coiling rope.In the time that pin is trampled bar lifting clothes-horse, manual coiling rope between fixed friction wheel and the semicircle annular groove of swing friction pulley moves down, the frictional force effect that swing friction pulley is now subject to manual coiling rope makes swing arm to lower swing, thereby make to swing friction pulley and leave fixed friction wheel, thereby manual coiling rope now and fixed friction wheel and to swing rolling frictional resistance between friction pulley minimum, so that the rising of clothes-horse.And need to make clothes-horse decline time, manual coiling rope between fixed friction wheel and the semicircle annular groove of swing friction pulley moves up, the frictional force effect that swing friction pulley is now subject to manual coiling rope upwards swings swing arm, thereby making to swing friction pulley, to take turns a side to fixed friction close, and then make to swing friction pulley and fixed friction wheel and clamp manual coiling rope, the rolling frictional resistance that manual coiling rope is subject to like this increases, thereby manual coiling rope is formed to effective damping buffering effect, can guarantee the steady decline of clothes-horse.While decline in order to ensure clothes-horse, have enough dampings, the angle between swing arm and manual coiling rope can be between 65 degree-75 degree.
It should be noted that, manual lifting mechanism is answered stationary housing when mounted, and like this, in the time of electric hoist clothes-horse, manual lifting mechanism just can not move up in the time being subject to the active force of pull rope.And housing should preferably be arranged near wall limit place, correspondingly, we can make pull rope can paste ceiling and metope layout by deflecting roller is set on ceiling and metope.
