Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention will be further described.
As shown in Figure 1, a kind of lift-type clothes-drying rack, it is applicable to the place that balcony one class has ceiling, installs so that hang.Specifically comprise lifting motor 1, stay cord 2, upper end are fixed on crane 3 on ceiling, be connected to crane lower end for the clothes-horse 4 of airing clothes and a manual lifting mechanism 5, crane then comprises the upper slide rail 31 be fixed on ceiling, connect with clothes-horse and be parallel to upper slide rail glidepath 32 and in X shape cross-articulation together with left connecting rod 33 and right connecting rod 34, the upper end thereof of left and right connecting rod has sliding shoe, this sliding shoe is slidably connected on slide rail, thus can be slided along upper slide rail in the upper end of left and right connecting rod; The lower end of left and right connecting rod is hinged with sliding shoe equally, and this sliding shoe is slidably connected on glidepath, thus can be slided along glidepath in the lower end of left and right connecting rod.Like this, when glidepath is together with clothes-horse rising or when declining, the upper and lower end of left and right connecting rod moves respectively or moves in centre on upper and lower slide rail outside two ends.Certainly, in order to ensure the parallel lifting of glidepath with clothes-horse, the length of left and right connecting rod should be equal, and its cross one another pin joint preferably should be positioned at the centre position of left and right connecting rod.
Manual lifting mechanism comprises a housing 51, and be provided with worm gear 52, the worm screw 53 engaged with worm gear and second reel 54 coaxial with worm gear in housing, the outer end that worm shaft stretches out housing arranges a crank handle 561.During hand crank handle, namely slow down by worm and gear and drive the second reel to rotate.In addition, lifting motor can be arranged on the upper slide rail of crane upper end, so that install, certainly also can be arranged in a casing, casing is then fixed on ceiling independently, also can arrange the controller controlling lifting motor action in casing.The output shaft of lifting motor is connected with a worm and gear gear, and the output shaft of this gear 11 connects first reel 12.The centre position of the glidepath of crane lower end arranges a movable pulley 6, correspondingly, on the upper slide rail of crane upper end or a fixed pulley 7 is set on casing, one end of stay cord is fixed and is wound on the first reel stackedly, fixing and be wound on the second reel after the other end of stay cord walks around movable pulley, fixed pulley successively stackedly.Certainly, we need offer through hole on the housing of manual lifting mechanism, so that the penetrating of stay cord.Because worm and gear has auto-lock function, therefore, the stay cord be wound on first, second reel can not discharge voluntarily.
When the electronic decline clothes-horse of needs, lifting controllable electric machine rotation, after worm and gear gear slows down, drive the first reel to rotate release stay cord, crane can at the stretch under application of the gravity of self gravitation and clothes-horse, glidepath is now communicated with clothes-horse and moves down, and the upper and lower end of left and right connecting rod moves respectively on upper and lower slide rail in centre, can airing clothes easily on clothes-horse.When the electronic lifting clothes-horse of needs, lifting controllable motor rotates backward, and to drive the first reel to rotate backward winding stay cord, thus is up promoted by clothes-horse, realize the automatic lifting of clothes-horse, now the upper and lower end of left and right connecting rod moves respectively on upper and lower slide rail outside two ends.Certainly, for the ease of controlling, we can arrange corresponding remote controller, to realize the lifting of remote control clothes-horse.
When running into power failure, lifting motor cannot normally work, now as clothes-horse height need be reduced, and can hand rotation crank handle, thus drive the second reel to rotate to discharge the stay cord be wound on the second reel by worm screw, worm gear, clothes-horse falling head can be made easily.Otherwise if need the height promoting clothes-horse, then can rotate backward crank handle, make the second reel rotate backward the stay cord that reels, clothes-horse is promoted, thus can realize the hand-operated lifting of clothes-horse thereupon.
For ease of installing and using, we also can arrange an angle pulley 8 on ceiling, and like this, stay cord first winding after walking around fixed pulley, on angle pulley, then is fixed and is wound on the second reel downwards.Preferably, angle pulley can be arranged on the outside of slide rail length direction, so that the stay cord be wound on downwards on the second reel can be avoided producing with clothes-horse interfering.In addition, the housing of manual lifting mechanism can be fixed on metope, so that user's exerting oneself when rotating crank handle.
For improving the stability of crane when being elevated, distinguish hinged one in the middle part of the epimere of left and right connecting rod cross-articulation point on, the other end of the upper auxiliary rod of auxiliary rod 35, two is hinged on and is located on the upper jointed shaft of slide rail.Correspondingly, the other end distinguishing a hinged lower auxiliary rod 36, two lower auxiliary rods in the middle part of the hypomere of left and right connecting rod cross-articulation point is hinged on to be located on the lower jointed shaft of glidepath.
In addition, manual lifting mechanism also can adopt foot-operated structure as shown in Figure 3, so that the use of old man, women.Particularly, manual lifting mechanism 5 comprises a housing 51, certainly, for ease of foot-operated, this housing can be arranged on the ground, offers a vertical stopper slot 511 before housing, rotating shaft 56, second reel 54 arranging left and right lateral arrangement in housing is located in rotating shaft.Rotating shaft being also provided with a driven wheel 562, correspondingly, housing then being arranged rotationally one for braking the ratchet 58 of driven wheel, thus form a click structure.The tail end of ratchet passes outside housing, so that manually remove the self-locking of driven wheel by the tail end stirring ratchet.Certainly, preferably torsion spring should be set on the turning cylinder of ratchet, so that ratchet abuts on driven wheel all the time.In addition, in housing, the left and right sides also arranges vertical guide rail 59 respectively, guide rail then arranges the sliding shoe that can slide up and down, a cross bar 50 is then connected between two sliding shoes in left and right, thus cross bar can be moved up and down along guide rail, upper end and the cross bar of one tooth bar 55 that can engage with driven wheel are hinged, cross bar is arranged the torsion spring pinning tooth bar, thus make that tooth bar is outward-dipping under the effect of torsion spring to be separated with driven wheel, the soffit of tooth bar then arranges the treadle 551 passing stopper slot before housing, the top being positioned at cross bar in housing also needs to arrange a wind spring 57, the outer end of wind spring is then connected with cross bar.
Like this, when needs hand hoisting clothes-horse, can be tramped with one's feet the treadle exposed outside housing, tooth bar now inwardly rotates around the cross bar of upper end on the one hand and is meshed with driven wheel, the elastic force then overcoming wind spring on the other hand moves down along guide rail, thus promoting driven wheel rotation, second reel coaxial with driven wheel rotates the stay cord that reels thereupon makes airer for clothes rise.When pin is trampled the lower limit of bar arrival stopper slot and is separated with treadle, ratchet then can play the self-locking action to driven wheel, thus avoid the rollback of the second reel to rotate, the torsion spring be arranged on cross bar then promotes tooth bar and outwards rotates and be separated with driven wheel, and wind spring now pulls cross bar to be communicated with tooth bar to rise along guide rail together and reset.Repeat above-mentioned action, clothes-horse can be made to rise to the height of needs.And when needs make clothes-horse decline, then available hand stirs the ratchet tail end passed outside housing, thus driven wheel is unlocked, now clothes-horse automatically can decline under the driving of gravity, unclamp the tail end of ratchet, ratchet can automatically reset and make driven wheel self-locking, thus makes clothes-horse drop to the height of needs.Can decline reposefully to make clothes-horse, so that control its falling head, we also can set firmly a fixed friction wheel 512 in housing near the second reel place, and a swing friction pulley 513 is set abreast on fixed friction wheel side, swing the lower end that friction pulley is rotatably connected on the swing arm 514 that is tilted, the acclivitous upper end of swing arm is then hinged on housing, housing is being provided with swing arm hinged place the torsion spring pinning swing arm, makes the swing friction pulley of swing arm lower end can be close to fixed friction wheel all the time.In addition, as shown in Figure 4, fixed friction wheel with swing friction pulley periphery on relative semicircle annular groove 515 is set respectively, stay cord then just screens fixed friction wheel with swing friction pulley semicircle annular groove between.
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, thus pushes down stay cord.When pin tramples bar lifting clothes-horse, between fixed friction wheel and the semicircle annular groove swinging friction pulley, stay cord moves down, the frictional force effect that swing friction pulley is now subject to stay cord makes swing arm to lower swing, thus make swing friction pulley leave fixed friction wheel, thus stay cord now and fixed friction wheel and the rolling frictional resistance that swings between friction pulley minimum so that the rising of clothes-horse.And when needing clothes-horse is declined, between fixed friction wheel and the semicircle annular groove swinging friction pulley, stay cord moves up, the frictional force effect that swing friction pulley is now subject to stay cord makes swing arm upwards swing, thus make swing friction pulley close to fixed friction wheel side, and then make swing friction pulley and fixed friction wheel clamping stay cord, the rolling frictional resistance that such stay cord is subject to increases, thus forms effective damping buffering effect to stay cord, can guarantee the steady decline of clothes-horse.Have enough dampings when declining in order to ensure clothes-horse, the angle between swing arm and stay cord can between 65 degree of-75 degree.
It should be noted that, the manual lifting mechanism of above-mentioned two kinds of structures answers stationary housing when mounted, and like this, when electronic lifting clothes-horse, manual lifting mechanism just can not move up when being subject to the active force of stay cord.But fixed installation can produce some inconvenience, so, preferably, the housing of manual lifting mechanism should be removable, for this reason, as shown in Figure 1, Figure 3, we can sheathed flexible sheath 21 on the stay cord between the second reel and angle pulley, the two ends of sheath arrange retainer plate 22 respectively, and the retainer plate near the second reel is fixed in housing outer surface, and the retainer plate of the other end is then fixed on ceiling near angle pulley place.Like this, when electronic lifting clothes-horse, the stressed tensioning of stay cord, because sheath can not be compressed, therefore stay cord cannot make manual lifting mechanism rise, that is, manual lifting mechanism can freely be placed on ground or be affiliated on metope, thus is conducive to simplifying installation, and convenient operation uses.
Finally, in order to utilize illumination fully and be convenient to the airing of clothing, as shown in Figure 2, clothes-horse 4 can comprise a rectangular frame 41, be positioned at oblong clothes hanger track 42 and quilt airing bar 43 below rectangular frame, quilt airing bar is positioned at the centre of clothes hanger track, certainly, quilt airing bar also can arrange two as required.Clothes hanger track is connected with rectangular frame by some connecting rods 44 with quilt airing bar, clothes hanger track can hang some clothes hangers 45, for the clothing that airing jacket, trousers one class are shorter, then can airing sheet, woollen blanket, article that quilt one class is longer on quilt airing bar in the middle of clothes hanger track, thus form height three-dimensional airing straggly.
In order to improve stability during clothes-horse lifting, crane can arrange two abreast, the lower end of two cranes is connected with two long limits of rectangular frame respectively, fixed pulley now can be set directly on the ceiling between two cranes, or the casing installing lifting motor is fixed on the ceiling between two cranes, then fixed pulley is arranged on casing, certainly, also connection cross bar can be set between the upper slide rail of two cranes, then fixed pulley is arranged on and connects on cross bar, thus be convenient to assembling.
Finally, in order to improve the uniformity of clothes drying, the cross section of clothes hanger track can be made into U-shaped, like this, can arrange chain drive-belt 46 in clothes hanger track, a drive motors 47 is set on rectangular frame simultaneously, the output shaft of drive motors is arranged the drive sprocket 48 engaged with chain drive-belt, drive sprocket is positioned at the side of clothes hanger track, certainly, the side of clothes hanger track needs to offer corresponding through hole, engages so that drive sprocket stretches in clothes hanger track with chain drive-belt.In addition, on chain drive-belt, compartment of terrain arranges some push rods 49 straight up, and clothes hanger is then suspended on clothes hanger track between two push rods, and the hook being suspended on clothes hanger track at clothes hanger is arranged the roller 451 that can roll on clothes hanger track.Like this, during drive motors work, chain drive-belt is made to do gyration in clothes hanger track by drive sprocket, and the push rod on chain drive-belt can promote clothes hanger along clothes hanger track reciprocating rotation, thus make clothing can be subject to the irradiation of sunlight equably, effectively solve the dry inconsistence problems caused because of mutually blocking of clothing.
