Description

The automatic clothes hanger of hand-operated elevation type balcony

The utility model relates to a kind of supporter of airing clothes, specifically is meant the automatic clothes hanger of hand-rail type balcony on the ceiling that is attached to things such as balcony.

Prior art: as Chinese patent (notification number: 2141425) " hoisting clothes-horse ", constitute by cross bar, pulley, rhombus four-bar mechanism, crossbeam, upper holder, ratchet, ratchet and rope, " liftable balcony airer " (notification number: 2090385) for another example, it also is made of four-bar mechanism and pulley, web, its common feature is, easy to use, fully save balcony space, but shortcoming is: do not have retractile rope curling mechanism, make troubles to the user.The patent that I applied in 94 years: proposed a kind of making and shine " sport car formula balcony automatic airing frame " (patent No.: 94214224.1) that the clothing frame can arbitrarily move forward and backward on clothes horse, but it can only be installed in the balcony outside, is unfavorable for that the family that balcony guardrail is housed now uses.

The purpose of this utility model is: propose a kind of can lifting freely, and can be installed in the automatic clothes hanger of hand-operated elevation type balcony on the ceiling of balcony etc.

Realize that scheme of the present utility model is as follows: it is by two symmetrically arranged clothes-horses 1, and two symmetrically arranged lifting suspension rods 2, and transmission device is formed, wherein each lifting suspension rod is all formed by being the movable four-bar mechanism that closes the knot connection, the upper end tie point of four-bar mechanism is equipped with connecting plate 3 by bearing pin, connecting plate middle part perforate, by bearing pin fixed pulley 4 is housed on it, after stay cord 5 is walked around fixed pulley 4, the one end is fixed on pass, the lower end node of four-bar mechanism, and two foots of four-bar mechanism lower end all are fixed with annulus, clothes-horse 1 passes this annulus and fixes on it, major technique feature of the present utility model is: above-mentioned transmission device is by shell 6, bearing pin 7, worm gear 8, worm screw 9, axle sleeve 10, handgrip 11 is formed, its structure is as follows, bearing pin 7 is fixed on the shell 6 after passing the worm gear 8 in tape spool hole, after worm screw 9 and worm gear 8 interlocks, axle sleeve is inserted at its two ends, and axle sleeve is fixed on the shell 6, the anchor ring of worm gear 8 also is provided with an annular groove, after above-mentioned two strands of stay cords 5 that are separately fixed at pass node under two lifting suspension rods are walked around fixed pulley 4, walk around commutation fixed pulley 12 again and pass the shell 6 of transmission device, be fixed in the cannelure of worm gear 8, handgrip 11 is fixed on the end of the worm screw 9 that stretches out shell 6 by pin.

The utility model has the advantages that: described clothes hanger is simple in structure, the operation is nimble, lifting freely, can make full use of the upper space in floor balcony or room, do not keep the sun off, do not occupy the lower layer space of usefulness, solved the problem of shining the clothing difficulty for the resident

The invention will be further described below in conjunction with accompanying drawing
