Fig. 3 is the structural representation under the decomposing state of coiling lifting assembly of the present utility model.

The specific embodiment

As Fig. 1, Fig. 2 and shown in Figure 3, a kind of Hand rocker for clothing-airing rack simple in structure described in the utility model comprises the coiling lifting assembly that shell 1, hand crank 2, two covers are made up of gear 3, arrestment mechanism 4, reel 5 and bearing pin 6.For solving the problem that the existing structure of existing Hand rocker for clothing-airing rack is comparatively complicated, production cost is higher, reliability is relatively poor, the gear 3 of two cover coiling lifting assemblies described in the utility model is meshing with each other together, described hand crank 2 is connected and installed in wherein on the bearing pin 6, and be respectively equipped with the socket joint type location structure between this bearing pin 6 and arrestment mechanism 4, the gear 3, the socket joint type location of described hand crank 2 by bearing pin 6 and arrestment mechanism 4, and bearing pin 6 and the socket joint type location of gear 3 realize that it switchably controls two cover coiling lifting assembly work.Like this, the utility model is compared with existing Hand rocker for clothing-airing rack, the main shaft and the gear that are arranged between the two cover coiling lifting assemblies have directly been saved, simplified the package assembly of whole Hand rocker for clothing-airing rack widely, reliability of products and service life have been improved, and saved parts, and directly reduced production cost, improved the competitiveness of product in market.As shown in Figure 3, described location structure can be made of limiting section 7 that is arranged at two sides on the bearing pin 6 and the spacing trepanning 8 that has corresponding limiting section that is arranged at arrestment mechanism 4, gear 3, and limiting section 7 and the suitching type socket spacing trepanning 8 of the spacing trepanning 8 of arrestment mechanism 4, gear 3 between of this bearing pin 6 by its two side realizes that hand crank 2 switchably controls two cover coiling lifting assembly work.Wherein, described limiting section 7 can be made the hex nut shape, perhaps square strip etc., at this moment, the trepanning of hexagonal shape in 8 of described spacing trepannings become accordingly, perhaps square hole etc., to make things convenient for the location that socket-connects of limiting section 7 and spacing trepanning 8, help hand crank 2 to finish switching.More reasonable for total, more help assembling, as Fig. 1 and shown in Figure 2, in general, described reel 5 is set in the middle part of bearing pin 6, described gear 3 and arrestment mechanism 4 are set with in the left and right side of bearing pin 6, and reel 5 is folded between it.In order to simplify composition structure of the present utility model further, again as shown in Figure 1 to Figure 3, described arrestment mechanism 4 comprises brake drum 41, tripping spring 42, brake drum cover 43 and is arranged at brake block 44 on reel 5 end faces, wherein tripping spring 42 is provided with a pair of blocking nose 45, and this tripping spring 42 is installed in the brake drum 41; Described brake drum cover 43 covers are packed in the brake drum 41, make jaggedly 46 thereon corresponding to the position of the blocking nose 45 of tripping spring 42, and the brake block 44 on the described reel 5 is plugged in this breach 46 and places this between the blocking nose 45.At this moment, it is comparatively reasonable that described spacing trepanning 8 generally is located at brake drum cover 43.Meanwhile, again in order to simplify composition structure of the present utility model more further, as shown in Figure 1 and Figure 2, described shell 1 comprises case 11, base plate 12, make a pair of groove 13 in the wherein said case 11 accordingly for arrestment mechanism 4 setting-ins, and wherein the bottom land of a groove 13 also is provided with axis hole 14, and described arrestment mechanism 4 is flush-mounted in the groove 13 accordingly; Be respectively equipped with two and groove 13 corresponding post holes 15 on the described base plate 12, this post hole 15 also is provided with bearing 9, described gear 3 and reel 5 two ends by bearing pin 6 be set with in the bearing 9 in post hole 15 with arrestment mechanism 4 in be installed between post hole 15 and the groove 13 in the corresponding bearing that is provided with 9, and wherein an end of a bearing pin 6 passes axis hole 14 accordingly and is connected with hand crank 2.Again in order to make the more favourable conserve space of the utility model, as Fig. 1 and shown in Figure 2, described hand crank 2 is made of handle 21 and rocking arm 22, wherein an end of rocking arm 22 is connected with bearing pin 6, the other end has been made embedding slot 23, and described handle 21 is embedded in the embedding slot 23 and by being articulated and connected of pivot pin by the interlocking end of making accordingly on it 24 and is connected with rocking arm 22 collapsibly.

In general, in order to improve compatibility between each part, make its assembling of being more convenient for, and the development cost that reduces parts, upper and lower two cover coiling lifting assemblies shown in Fig. 1 and Fig. 2, except the bearing pin of top coiling lifting assembly was grown slightly than the bearing pin of following coiling lifting assembly, its structure was consistent basically.Certainly, the upper and lower two cover coiling lifting assemblies shown in Fig. 1 and Fig. 2 also can be made structure differing from each other.

Whole Hand rocker for clothing-airing rack operation principle process of the present utility model is such:

Structure after whole clothes hanger of the present utility model assembles is basic as Fig. 1 and shown in Figure 2.For example,, hand crank 2 can be extracted outward out the limiting section 7 that makes bearing pin 6 upper left sides and spacing trepanning 8 on the brake drum cover 43 of arrestment mechanism 4 location that socket-connects when coiling lifting assembly when work that will shake the top among the figure; Simultaneously, 7 of the limiting sections on right side are thrown off mutually with the spacing trepanning 8 on the gear 3 on this bearing pin 6, form idle running between the gear 3 on this bearing pin 6 and its right side, and gear 3 can not be driven to this moment, also just can not be driven into the coiling lifting assembly of lower part; The structure of this moment can be shaken hand crank 2 as shown in Figure 1, has normally controlled the coiling lifting assembly work on this top.

On the contrary, in the time will shaking the coiling lifting assembly work of the lower part among the figure, hand crank can be pushed away toward in, the limiting section 7 that makes bearing pin 6 upper left sides is thrown off mutually with the spacing trepanning 8 on the brake drum cover 43 of arrestment mechanism 4, the rotation of this bearing pin 6 this moment is can not be driven into the brake drum cover of arrestment mechanism 4 43 to rotate, and also just can not drive the coiling lifting assembly work on top; Simultaneously, 7 of the limiting sections on right side enter the spacing trepanning 8 on the gear 3 on this bearing pin 6, with spacing trepanning 8 on the gear 3 location that socket-connects; The structure of this moment can be shaken hand crank 2 as shown in Figure 2, and the gear 3 of the coiling lifting assembly by top drives the gear 3 of the coiling lifting assembly of lower parts, coiling lifting assembly work that can this lower part of driven.
