Hanger pipes for easy joining {PIPE FOR HANGER}

The present invention relates to a pipe used for a hanger hanger or a clothes dryer hanger, and more particularly, it is possible to easily combine the two pipes in a hanger pipe composed of two pipes joined to be disposed on the same center line. It is about a hanger pipe.

In general, the length of the long hanger pipe is divided into two or more for ease of packaging and transport, and then used to combine them when installing the hanger.

On the other hand, as a technology for easily joining the pipe divided into two or more, including the hanger pipe, Korean Utility Model Registration No. 20-0277747 (registered on May 27, 2002, hereinafter referred to as 'prior art') Pipe connection structure ”is presented.

The above-mentioned prior art is a "hollow pipe, wherein one end of the pipe is formed with a shaft tube portion having an outer circumferential diameter smaller than the outer circumferential surface diameter of the pipe, and the other pipe is formed at the shaft tube portion of the portion connected to the outer circumferential surface of the pipe. As a step is formed in contact with the end of the "

Not only is the shape of the joined pipes beautiful, but also a technology that facilitates the coupling and separation of the pipes.

The prior art allows the two pipes to be easily coupled by inserting the shaft pipe formed at one end of the pipe into the inner circumferential surface of the other pipe.

When the shaft pipe part is loosely inserted into the inner circumferential surface of the pipe, the two pipes are easily separated, so there is a problem that it is not suitable for applying to the hanger pipe.

In addition, when the shaft pipe portion is closely inserted into the inner circumferential surface of the pipe, the two pipes may be firmly coupled, but there is a problem in that the coupling is not easy because a large force is applied to the two pipes.

In order to solve the above problems, a pipe for a hanger that can be easily coupled according to the present invention,

First and second pipes disposed on the same center line; And

Mutual coupling means for the first and second pipes;

, &Lt; / RTI >

The coupling means

A main coupling portion is formed in one end of the second pipe and is forcibly fitted to the inner circumferential surface of the first pipe, and

A sub-coupling portion formed at one end of the main coupling portion and loosely fitted to an inner circumferential surface of the first pipe.

.

Here, the main coupling portion and the sub coupling portion may be formed with a slit crossing the shape.

And the inner peripheral surface of the first pipe is formed with a raised guide at the end facing the second pipe,

Concave guides are formed on the outer circumferential surface of the main coupling portion so that the guides pass through when the first and second pipes are coupled to each other.

The corresponding guide may have a spiral structure.

Here, the outer coupling surface of the sub-coupling portion is connected to the corresponding guide, when the first and second pipes are formed in the concave-type sub-corresponding guide through the guide,

The sub-corresponding guide may have a straight structure.

Hanger pipe easy to join according to the present invention,

Since the main coupling portion is finally coupled to the first pipe in a state where the sub coupling portion is initially coupled to the first pipe in a loose fitting structure, not only the first and second pipes are easily coupled, but also they are firmly coupled to each other. It works.

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

As shown in Figures 1 to 4, hanger pipes (hereinafter, referred to as 'hanger pipes') that are easily coupled according to an embodiment of the present invention are largely the first pipe 100, the second pipe 200 and It consists of a coupling means (300).

As shown in Figure 1 and 2 hanger pipe according to an embodiment of the present invention is a support pipe of the vertical pipe (11) and horizontal pipe (12), or laundry drying rack (20) forming a hanger hanger (10). (21) and the hanger pipe (22) and the like, in addition to a variety of pipes, such as a shelf for placing things or means for hanging things.

Hereinafter, each configuration will be described with reference to FIGS. 3 and 4.

The first and second pipes 100 and 200 are

They have the same outer diameter and are arranged on the same center line.

The coupling means 300 is

As for coupling the first and second pipes 100 and 200 to each other,

A main pipe 310 is formed at one end of the second pipe 200 and is forcibly fitted to the inner circumferential surface of the first pipe 100, and

A shaft pipe is formed at one end of the main coupling part 310, and the sub coupling part 320 is loosely fitted to the inner circumferential surface of the first pipe.

That is, the coupling means 300 has a two-stage structure so that the outer diameter of the second pipe 200 is sequentially reduced.

On the other hand, the above "inhibition fit" means that when the physical force is applied, for example, the outer diameter of the main coupling portion 310 is the inner diameter of the first pipe (100) This means that the main coupling part 310 is not inserted into the first pipe 100 naturally and is inserted only when a physical force is applied because it is larger than or equal to the main coupling part 310.

In addition, the "loose fitting" means that the outer coupling of the sub coupling unit 320 is smaller than the inner diameter of the first pipe as opposed to the interference fitting, so that the sub coupling unit 320 does not apply a physical force. Means that is naturally inserted into the pipe (100).

As a result, according to the fitting structure of the coupling means 300 as described above, the main coupling portion 310 in the state in which the sub coupling portion 320 is initially coupled to the first pipe 100 in a loose fitting structure By the final coupling in the interference fitting structure to the first pipe 100, not only the coupling of the first and second pipes (100, 200), but also can be firmly coupled to each other.

That is, even if a large force is applied to insert the main coupling part 310, the first and second pipes 100 and 200 are in the state of being inserted into the first pipe 100. Are easily combined without shifting each other.

The main coupling part 310 and the sub coupling part 320 may be formed by swaging the end of the second pipe 200 when the second pipe 200 is made of metal. When the second pipe 200 is made of synthetic resin, the second pipe 200 may be formed by injection molding together with the second pipe 200.

Hereinafter, a hanger pipe according to another embodiment of the present invention will be described with reference to FIGS. 5 and 6.

For reference, "A" of FIG. 6 shows an enlarged cross section of the corresponding portion.

As shown in FIG. 5, according to the hanger pipe according to another embodiment of the present invention, the main coupling part 310 and the sub coupling part 320 are formed with slits 330 that cross them. .

The slit 310 is formed in two places as shown is preferably disposed on both sides of the main coupling portion 310 and the sub coupling portion 320,

If necessary, three or more places may be formed and arranged radially with respect to the center line of the second pipe 200.

The main coupling portion 310 is elastically deformed inward when the main coupling portion 310 is inserted into the first pipe 100 by the slit 310 formed as described above, so that the first and second pipes 100 and 200 are more easily coupled. Will be lost.

And, as shown in Figure 6, according to the hanger pipe according to another embodiment of the present invention,

On the inner circumferential surface of the first pipe 100, a raised guide 110 is formed at an end facing the second pipe 200,

An outer concave guide 311 is formed on the outer circumferential surface of the main coupling part 310 so that the guide 110 passes through when the first and second pipes 100 and 200 are coupled to each other.

Wherein the corresponding guide 311 is made of a spiral structure,

Accordingly, the first and second pipes 100 and 200 may be opposite to the first and second pipes 100 and 200 in a state where the guide 110 is located in the corresponding guide 311. It is possible to easily combine or separate from each other by the operation of turning to.

On the other hand, as shown in the outer circumferential surface of the sub-coupling portion 320 is connected to the corresponding guide 311, when the first and second pipes (100, 200) is coupled to the yo The vertical sub-corresponding guide 321 is formed.

The sub-corresponding guide 321 guides the guide 110 so that the guide 110 easily enters the corresponding guide 311 when the first and second pipes 100 and 200 are coupled. It is preferable to have a linear structure.
