The ends of the above hook 20 are pivotally coupled by the folding connector 30 and the shaft 40, so that the support 10 is erected or folded in an unfolded state on the ground, and the hook 20 is supported by a support ( 10 is formed to be expanded or folded to both sides, the folding connector 30 is a plurality of rotational connection member 31 is coupled to the end of the connection pipe 11, 21 of the support 10 and the hanger 20 In the foldable clothes drying rack 1 is configured to be rotatably supported mutually coupled;

A hinge hole 31a which is formed to coincide with each other in the pivotal connection member 31 of the folding connector 30 coupled to the connection pipes 11 and 21 of the support 10 and the hanger 20; A fitting bushing 70 fixedly coupled to the shaft bar 40 by a punching process after being fitted to the end of the shaft bar 40, and having a fitting coupling hole 71 penetrated therein; The pivotal connection member at one end of the shaft portion 81 inserted into the hinge hole 31a formed in the pivotal connection member 31 of the folding connector 30 and the fitting hole 71 of the coupling bushing 70. A locking head 82 is formed at the inlet of the hinge hole 31a of the 31, and an elastically elastically caught at the fitting hole 71 of the coupling bushing 70 at the other end of the shaft portion 81. Coupling pin 80 is formed with a locking projection (83); The foldable connector 30 and the shaft bar 40 coupled to the connecting pipes 11 and 21 of the support 10 and the hanger 20 are fixedly coupled to each other by integrally.

The outer circumferential edge of the shaft portion 81 of the coupling pin 80 coupled to each other and the inner circumference of the fitting hole 71 of the coupling bushing 70 may be mutually engaged as shown in FIGS. 4 and 5B in some cases. The multi-stage catching projection 86 and the multi-stage catching groove 74 which are fixed while being caught are formed to correspond to each other, and may be configured to adjust the coupling length of the coupling pin 80 and the coupling bushing 70.

The support 10 is rotatably coupled to the end of the base 50 to support or fix the hanger 20 in the unfolded state, and fixed the interval of the support 10 in the standing state between the two support (10) The spacing holder 60 is configured to support the coupling.

One end of the fitting hole 71 of the coupling bushing 70 is integrally coupled by the shaft rod 40 and the punching process, as shown in Figure 6a and 6b of the coupling pin 80 The expansion of the elastic locking projections 83 is expanded and the elastic locking projections 83 of the coupling pin 80 is reduced after passing through the engaging skirt (72) elastically caught on the elastic locking projections (83) of the coupling pin (80). Can be formed and configured.

In addition, in some cases, a cutting hole 73 is formed in the engaging skirt 72 of the coupling bushing 70, and a cutting hole 84 is formed in a portion of the elastic locking protrusion 83 of the coupling pin 80. In addition, the coupling pin 80 elastically easily enters the fitting coupling hole 71 of the coupling bushing 70, and the elasticity of the coupling pin 80 in the fitting coupling hole 71 of the coupling bushing 70. The locking protrusion 83 may be configured to be easily elastically locked.

In some cases, as shown in FIGS. 7A and 7B, the entrance fixing hole 85 penetrates the inside of the coupling pin 80, and the entrance fixing hole 85 of the coupling pin 80 is formed. Fixing pins 90 each having an entry locking protrusion 91 and a fixed head portion 92 are fitted at both ends thereof so that the fitting holes 71 of the hinge hole 31a and the coupling bushing 70 of the pivot connection member 31 are fitted. It may be configured to be more stably fixed to the coupling pin (80) inserted into.

When assembling the foldable laundry dryer 1 of the present invention configured as described above, first, the coupling bushing 70 is inserted into the end of the shaft 40, and the outer periphery of the shaft 40 in which the coupling bushing 70 is embedded is punched out. By combining the coupling bushing 70 and the shaft 40 in advance integrally.

Then, by combining the pivotal connection member 31 of the folding connector 30 coupled to the connecting pipes 11 and 21 of the support 10 and the hanger 20 to match the hinge hole (31a) and the shaft bar (40) ) To match with the coupling bushing (70).

Thereafter, the engaging pin 80 enters through the fitting hole 71 of the hinge hole 31a and the coupling bushing 70 of the matched folding connector 30, and the locking head portion 82 of the coupling pin 80 is inserted. ) Is caught by the folding connector 30 and at the same time the elastic engaging projection 83 of the coupling pin 80 is passed through the fitting coupling hole 71 of the coupling bushing 70 and fixed to the end of the fitting coupling hole 71. By combining so that the folding connector 30 and the shaft 40 is integrally combined.

In this case, that is, when the coupling pin 80 enters the fitting hole 71 of the coupling bushing 70, the cutting hole 84 of the coupling pin 80 and the cutting hole 73 of the coupling bushing 70 are used. By the elastic engaging projection 83 of the coupling pin 80 and the engaging skirt 72 of the coupling bushing 70 are mutually corresponding to each other smoothly passed through the elastic expansion and contraction of the coupling bushing (70) ), The engaging skirt 72 and the elastic engaging projection 83 of the coupling pin 80 can be caught and fixed.

Subsequently, when the end of the connecting pipe 11, 21 of the support 10 and the hook 20 to the rotary connecting member 31 of the folding connector 30, the assembly of the folding laundry dryer 1 of the present invention is assembled. Is done.

On the other hand, the action of the present invention fold-type laundry drying rack 1 is configured as follows.

In order to rotate the support stand 10 and the hanger 20 of the folding clothes drying rack 1 for the installation and storage of the present invention, the folding clothes drying rack 1, the support rod 10 and the hanger ( Even if the connecting pipes 11 and 21 of the connecting pipes 11 and 21 of the folding connector 30 and the coupling pins 80 of the connecting pipes 11 and 21 are rotated in contact with each other by sliding, the elastic locking stones of the fixing pins 90 are rotated. Since the machine 83 is not caught and caught by the engaging skirt 72 of the coupling bushing 70, the coupling state of the coupling pin 80 and the coupling bushing 70 can be stably maintained. 1) Even if the support 10 and the hanger 20 are rotated repeatedly for installation and withdrawal, that is, the pivot of the pivot connecting member 31 coupled with the support 10 and the hanger 20 is repeated. Even if it is made, the coupling of the coupling pin 80 and the coupling bushing 70 is not released And it is possible to firmly maintain the engaged state of folding the connector 30 and the shaft seal (40).
