The present invention relates to a foldable connector, and more particularly, to a foldable connector configured to stably maintain and secure the connected pipe rotated for a certain period while supporting the plurality of connection pipes in a mutually rotatable manner.

In general, the foldable connector for supporting the plurality of connecting pipes to be rotatable with each other, as shown in Figure 1, the plurality of rotating plate members 31 are rotatably overlapped and supported by the hinge shaft 32, The outer circumference of the rotating plate member 31 is formed integrally projecting the pipe connecting portion 31a to which the connecting pipes 11 and 21 are coupled, and the hinge shaft 32 is inserted into the center of the rotating plate member 31. The hinge hole 31b is formed and comprised.

The folding connector 30 is applied to a variety of mechanisms or devices that allow the plurality of connecting pipes (11) (21) to be folded or unfolded, especially the support (10) of the folding clothes drying rack (1) The connecting pipes 11 and 21 of the hanger are widely used in the case of mutually rotatable support coupling.

The folding clothes dryer 1 to which the conventional folding connector 30 is applied is provided with a plurality of hook bars 12 inside the connecting pipes 11 and 21 that are bent into a shape as shown in FIGS. 2 and 3. 22 is coupled to the support 10 and the end of the connecting pipe (11, 21) of the support 20 made of a support 20 is coupled to the pipe connecting portion (31a) of the folding connector 30, respectively, the support (10) Is built or folded in a state unfolded on the ground, the hanger 20 is configured to be folded or folded to both sides of the support (10).

In addition, the support 10 is rotatably supported by a support 50 for supporting or fixing the hanger 20 in an unfolded state, and the space between the supports 10 in an upright state is established between the supports 10. Fixing and holding the spacer 60 is configured to support.

In addition, the support pipe 10 and the hook connection pipe (11, 21) of the end of the connecting pipe 30 and the folding connector 30 is coupled between the support 10 and the hook connecting pipe (11) (21) A shaft rod (40) for fixing the width is supported, wherein the hinge shaft (32) is fitted to the end of the shaft rod (40) is fixedly coupled to the hinge coupling piece (33).

In the case of installing the conventional folding laundry dryer 1 configured as described above, each hinge shaft 32 of the rotary plate member 31 of the folding connector 30 to which the connecting pipes 11 and 21 of the support 10 are coupled. Rotate to expand around the center of the support (10) is rotated so as to be fully unfolded, and then the support (10) is installed on the ground, and then installed The rotating plate member 31 of the folding connector 30 coupled to the connecting pipes 11 and 21 of the hanger 20 is rotated about the hinge shaft 32 to be unfolded, and then the hanger 20 is supported by the pedestal 50. ), The installation of the folding clothes drying rack (1) is completed.

By the way, the conventional foldable clothes dryer (1) is applied to the folding connector 30 in the state in which the support 10 and the hanger 20 is installed on the ground in an unfolded state, the user accidentally installed the support (10) or hanger When touched (20), the support 10 or the hanger 20 is easily rotated and fold while there is a problem such that the foldable laundry drying stand (1) installed standing on the ground falls and loses its center.

The present invention has been proposed in view of the above problems, and its purpose is to connect the plurality of connecting pipes to be rotatable with each other to allow the plurality of connecting pipes to be folded or unfolded as well as to rotate the connected pipes for a certain period. It is an object of the present invention to provide a folding connector configured to be stably fixed.

According to a feature of the present invention for achieving the above object, at least one fold connector consisting of two rotary plate members having a pipe connecting portion to which the connecting pipe is coupled is integrally rotatably supported by a hinge shaft, at least one The boss portion protrudes from the center of the rotation plate member peripheral portion of the foldable connector, characterized in that formed on the periphery of the two rotation plate member located on the outer side of the boss portion is formed so that the engaging projection and the engaging groove is formed to correspond to each other.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, the folding connector.

Figure 4 is an exploded perspective view showing a folding connector according to an embodiment of the present invention, Figure 5a and Figure 5b is a perspective view and a cross-sectional view showing an assembled state of the folding connector of the present invention.

As shown in the present invention, the folding connector 30 is rotatable by the hinge shaft 32 of the two rotating plate member 31 provided with a pipe connecting portion 31a to which the connecting pipes 11 and 21 are coupled. In the folded connector 30 is configured to be integrally supported coupled,

A boss portion 31c protrudes from the center of at least one circumference of the at least one rotating plate member 31, and the engaging protrusion 31d is inserted into and separated from the peripheral portions of both rotating plate members 31 located outside the boss portion 31c. The engaging groove 31e is formed to correspond.

A guide gradient surface 31f for allowing the locking projection 31d to be in close contact with the locking plate 31e to be inserted into the locking groove 31e while being slipped in close contact with the locking groove 31e and the locking groove 31e. The stopper step (31g) is formed so as to connect with the engaging groove (31e) to be caught and fixed to the engaging projection (31d) inserted into the.

The action of the fold-type clothes dryer (1) to which the fold connector 30 of the present invention configured as described above is applied as follows.

When installing the folding laundry drying rack 1 to which the folding connector 30 of the present invention is applied, the rotary plate member 31 of the folding connector 30 to which the connecting pipes 11 and 21 of the support 10 are coupled is provided. Each of the hinge shafts 32 is pivoted and unfolded, but the pivoted support 60 between the supports 10 is rotated and unfolded so as to be fully unfolded, and then the support 10 is placed on the ground. Install.

Subsequently, the rotary plate member 31 of the folding connector 30 coupled to the connecting pipes 11 and 21 of the hanger 20 is rotated about the hinge shaft 32 to be unfolded, and then extended to the pedestal 50. When the hanger 20 is supported and fixed, the installation of the folding clothes drying rack is completed.

In this case, that is, when the rotating plate member 31 of the folding connector 30 coupled to the connecting pipes 11 and 21 of the support 10 or the hanger 20 is rotated, the hinge shaft 32 mutually As the locking projection 31d of the one side rotating plate member 31 that is overlapped and integrally supported and coupled to the guide gradient surface 31f of the other rotating plate member 31 is inserted into and fixed to the locking recess 31e within the above, The unfolded state of the support 10 and the hanger 20 erected on the ground can be stably maintained.

On the other hand, the folding connector 30 of the present invention is not limited to the folding clothes drying rack 1 as shown in the detailed description and drawings, it can be used in other fields and devices.

In addition, the reference numerals which are not described or shown in the detailed description and the drawings of the present invention are the same as the prior art.

As described above, the foldable connector of the present invention is configured to be formed so as to correspond to the engaging projection and the engaging groove which are inserted into and removed from each other in contact with the plurality of rotating plate members, so that the foldable connector is folded or unfolded while being rotated by the foldable connector. When coupled to support, there is an effect that can maintain a stable state after the rotation of the connecting pipe.
