Description

The outer extension type clothes horse of balcony

The utility model relates to the outer extension type clothes horse of a kind of balcony.Be specially adapted to skyscraper user's use.

The clothes horse of the outer use of balcony now, the overwhelming majority is the frame clothes hanger that support and rope or cross bar are linked together, or the overhanging formula clothes horse of stock, the outer clothes horse of these balconies all exists the airing amount not enough, remote airing is shortcoming such as inconvenience again, and it is convenient to make the high residential building family be difficult to enjoy desirable outdoor airing.

The purpose of this utility model is exactly at the deficiencies in the prior art, provides a kind of balcony outer extension type clothes horse.Mainly solve in same leading screw can not displacement problem, the leading screw of different pitch is organically linked together, form the displacement leading screw, propeller is moved with different speed in different pitch section, thereby the realization clothes airing rod is released when airing one by one, utilize limited balcony length, increase airing length, make the resident of high residential building can enjoy the convenience of more outdoor airing clothes and bedding.

The purpose of this utility model can realize by following measure:

The outer extension type clothes horse of a kind of balcony, comprise carriage (1), support bar (2), suspension ring (3), fixed head (4), bolt (5), handwheel (6), cross bar (7), with fixing chain (13), carriage (1), support bar (2), forming two triangle frames with fixing chain is fixed on the balcony exterior wall by fixed head (4) and bolt (5), cross bar (7) is enclosed within and is arranged under the carriage (1) in the suspension ring (3), be provided with displacement leading screw (11) in carriage (1) inner chamber, the two ends of displacement screw mandrel (11) are provided with bearing (9), one end of displacement leading screw (11) is equipped with handwheel (6), two displacement leading screws (11) are by band (8) connection synchronously, displacement leading screw (11) is provided with propeller (10), is connected with suspension ring (3) under the propeller (10).

Described displacement leading screw (11) is provided with short pitch, long pitch and transition pitch, and the pitch of transition pitch is greater than the pitch of short pitch, less than the pitch of long pitch.

Described propeller (10) is reinforced cover (15) by propeller building ring (14) and propeller and is formed, the shape of propeller building ring (14) and the shape of thrust washer are similar, its cylindrical is provided with propeller and reinforces cover (15), in the propeller building ring (14): 1: 1＞β: α＞1: 10; 1/4 Φ 〉=K 〉=1/8 Φ; R=tg (90 °-(alpha-beta)/2) K; L equals leading screw screw thickness; The H value is less than the short pitch of leading screw; Wherein: α is the helical angle of the short pitch of leading screw, and β is the helical angle of the long pitch of leading screw, and Φ is a warp in the propeller building ring; K is a constant; R is a transition arcs; L is a distance between the transition arcs; H is a propeller building ring thickness.

The utility model compared with prior art has the following advantages: outer can the stretching of balcony stopped up the formula clothes horse, easy to operate and safe reliably, lodge clothing and bedding nearby, clothes airing rod stretches out at a distance one by one, utilizes limited balcony length, increases outdoor airing clothes and bedding.

Description of drawings is as follows:

Fig. 1 is a front view of the present utility model;

Fig. 2 is a vertical view of the present utility model;

Fig. 3 is displacement leading screw and angle of rake assembling diagrammatic sketch;

Fig. 4 is the propeller structure schematic diagram;

Fig. 5 is a propeller building ring structure chart;

Be described in further detail by embodiment below in conjunction with accompanying drawing:

The product structure that stretches out one meter with four cross bars is an example, it by carriage 1, support bar 2, suspension ring 3, fixed head 4, spiral shell select 5, handwheel 6, cross bar 7, be with 8 synchronously, bearing 9, propeller 10, displacement leading screw 11, plug 12, fixedly chain 13, propeller building ring 14 and propeller are reinforced cover 15 and are formed.

By carriage 1, support bar 2, displacement leading screw 11, fixedly the triangle frame of chain 11 compositions is installed in the two ends of balcony, the two ends of displacement leading screw 11 and carriage 1 are by bearing fixing, the A end of displacement leading screw 11 is short pitch, the B end is long pitch, the pitch of long pitch is 4 times of short pitch, if short pitch is L1, long pitch L2, be that 4L1=L2 L2=48mm L1=12mm Δ L=30mm (Δ L is a transition pitch) propeller 10 is contained on the displacement leading screw 11 in certain sequence, suspension ring 3 under the propeller 10 are enclosed within the suspension ring 3 by the cross bar 7 that the notch under the carriage 1 reaches carriage 1, reach displacement screw mandrel 11 1 ends in the balcony and install between handwheel 6, two handwheels 6 by being with 8 to connect synchronously, value is Φ=21mm in the propeller building ring 14, α=60 °, β=15 °, R=12mm, L=5mm.

Mode of operation, when four cross bars all are recovered to the A end, every bar is at a distance of 20mm, operation handwheel 6, each cross bar reaches the airing position fast and locates about 200mm from the balcony distance, when the first bar lodge finishes, operate handwheel 6, the second bars again and reach the airing position, first cross bar and second cross bar are at a distance of the 200mm advanced in unison, so live multiple operation, third and fourth cross bar also stretches out one by one, when first cross bar reaches the B end, four cross bars are all to stretch out at a distance of 200mm, the 4th cross bar can reach apart from balcony 400mm place, and reverse operating handwheel 6 during withdrawal, cross bar will be recovered to the A end one by one.
