2 is a perspective view illustrating a duct connection structure according to the present invention.
3 is a perspective view for explaining the formation of the coupling protrusion of the duct connecting structure according to the present invention;

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

1 and 2, the present invention relates to a connecting structure of a duct in which a main duct 10 and a connecting duct 30 can be easily assembled, and includes a plurality of connecting protrusions 11, A plurality of connecting members 20 coupled to the connecting duct 30 and an engaging groove 31 formed in the connecting duct 30.

In addition, the main duct 10 and the connecting duct 30 may have a polygonal shape having a circular cross section, an ellipse, a quadrangle, or a pentagon.

A plurality of the coupling protrusions 11 protrude from the outer surface of the main duct 10. The coupling protrusions 11 protrude from the outer surface of the main duct 10 made of stainless steel , And the pliers 40 manufactured in advance.

As shown in FIG. 3, the pliers 40 are formed in a shape similar to that of a conventional pliers. The pliers 40 are formed as a pair of head portions of the pliers 40, The pressing projection 41 and the pressing groove 42 are formed so as to coincide with the projection 11.

At this time, the pressing protrusion 41 is formed at the tip end of one of the pair of clamps, and has a shape corresponding to the coupling protrusion 11 and is protruded.

When the pair of clamps are engaged with each other, the pressing protrusion 41 is accommodated inside the pressing groove 42, .

When the engaging projection 11 is formed to protrude from the outer surface of the main duct 10 through the pressing protrusion 41 and the pressing groove 42, The other end of the main duct 10 is positioned between the pair of pliers 42. Then, a force is applied to the handle of the pliers 40 to pierce the pair of pliers.

That is, the other end of the main duct 10 is positioned between the pressing protrusion 41 and the pressing groove 42, and the pressing protrusion 41 is positioned to be in close contact with the inner surface of the main duct 10 The pressing projection 41 is positioned on the inner side of the main duct 10 so that the pressing projection 41 is positioned on the inner side of the main duct 10, So that a part of the other end of the main duct 10 is cut, and the coupling protrusion 11 is formed on the outer side of the main duct 10 to protrude.

The connecting member 20 is fitted on the outer surface and a part of the inner surface of the main duct 10 at a position where the coupling protrusion 11 is formed and is fitted on the coupling protrusion 11 A guide piece 22 bent outward at one side of the upper surface side for guiding the fitting of the connecting member 20 into the engaging projection 11, And a latching piece 23 formed to be bent outwardly from the end portion and hooked to the latching groove 31.

It is preferable that the connecting member 20 is made of a material having a self-elastic restoring force such as a leaf spring or the like when the connecting member 20 is fitted into the main duct 10, So that the fitting groove 21 can be easily inserted into the coupling protrusion 11 while the upper side of the coupling protrusion 11 flows to the outside to a certain extent and moves on the upper side of the coupling protrusion 11 to one side.

In addition, when the connecting member 20 is engaged, the upper side of the connecting member 20 flows to the outside to some extent, and the fitting of the connecting member 20 is guided through the guide piece 22, And the coupling protrusion 11 is inserted into the fitting groove 21 so that one end of the fitting groove 21 is engaged with one end of the coupling protrusion 11, (20). ≪ / RTI >

When the main duct 10 and the connecting duct 30 are connected to each other, the connecting duct 30 is connected to the main duct 10 so that the inner surface of the main duct 10 surrounds the outer surface of the connecting duct 30. [ When the engaging piece 23 of the connecting member 20 is pressed from the outer surface of the connecting duct 30 and is caught in the engaging groove 31, the engaging groove 20 is seated in the engaging groove 31 through a restoring force At the same time, the main duct 10 and the connecting duct 30 can be firmly held in the state where the main duct 10 and the connecting duct 30 are engaged with each other.

The locking groove 31 is formed to have a concave shape along the outer surface of the connecting duct 30 so that when the main duct 10 and the connecting duct 30 are connected, 23) will be caught.

Here, the latching groove 31 is formed to have a concave shape along the outer surface of the connecting duct 30. The latching groove 31 is formed so as to be inclined with a straight line on one side of the center, As shown in Fig.

As a result, there is no fear that the latching pieces 23 hooked on the latching grooves 31 are separated from one side, so that the state in which the main duct 10 and the connecting duct 30 are connected can be maintained firmly .

The main duct 10 and the connecting duct 30 are coupled to each other and connected to each other so that the engaging pieces 23 seated in the engaging grooves 31 can be moved along the engaging grooves 31 It becomes possible to rotate.

When the main duct 10 and the connecting duct 30 are connected to each other to change the angle between the main duct 10 and the connecting duct 30 during installation or installation of the duct, It is easy to change the angle of the main duct 10 and the connecting duct 30 so that maintenance of the duct installation work can be facilitated.

The connecting duct 30 may have a T-shaped, L-shaped, Y-shaped, I-shaped or polygonal cross-section.

The connecting duct 30 has a convex shape along the outer side surface and a stopper 32 is protruded so that when the main duct 10 and the connecting duct 30 are connected to each other, The operator can recognize that the connection and coupling between the main duct 10 and the connecting duct 30 are completed and the main duct 10 and the connecting duct 30 are connected to each other So that the deformation of the main duct 10 and the connecting duct 30 can be prevented.

When the main duct 10 and the connecting duct 30 connected to each other are to be separated from each other, one end of the fitting groove 21 is pushed to one side by using a tool such as a pin, So that the main duct 10 and the connecting duct 30 can be easily separated from each other and the disassembling operation of the duct can be facilitated.

As a result, the connection structure of the duct according to the present invention can simplify the installation and installation of ducts by connecting a plurality of connecting members to the main duct and sandwiching the connecting ducts to the main duct, so that unskilled operators can be easily connected and installed. The operation time can be shortened and the construction cost can be reduced and the main duct and the connecting duct can be rotated while being connected to each other, The main duct and the connecting duct can be easily separated from each other by removing the connecting member from the coupling protrusion, thereby facilitating the disassembling operation of the duct.

The present invention is not limited to the above-described embodiments. Anything having substantially the same constitution as the technical idea described in the claims of the present invention and achieving the same operational effect is included in the technical scope of the present invention.
