In addition, the embossed surface formed with a plurality of irregularities is formed on the surface in contact with the rubber ring of the protruding jaw constituting the coupling plate.

In addition, at least one ring having a predetermined thickness is further inserted between the protrusion of the coupling plate and the rubber ring.

In addition, the two holders are formed with a reinforcing ring insertion groove extending along the inner diameter of the sixth horizontal portion, and the reinforcing ring insertion groove is characterized in that the reinforcing ring of rubber material is inserted.

In addition, the rubber plate is inserted between the inner diameter of the sixth horizontal portion and the outer diameter of the tube when the two holder and the tube are coupled.

In addition, the second inclined portion and the fourth inclined portion is characterized in that the inclination angle is not formed the same.

Accordingly, the configuration of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily understand and reproduce.

1 is a perspective view according to an embodiment of the present invention, Figure 2 is an exploded perspective view according to an embodiment of the present invention, Figure 3 is a cross-sectional view according to an embodiment of the present invention, one end is the tube (1) It is connected to the inner diameter of the tube 1 is extended to a certain length equal to the inner diameter of the tube (1), the tube inserting portion 21 in which the inner diameter is extended so as to correspond to the outer diameter of another tube (1 ') is inserted into the end thereof ), A rubber ring mounting portion 22 whose inner diameter extends at an angle to the end of the tube inserting portion 21, and a coupling plate inserting portion 23 extending slightly from the rubber ring mounting portion 22 to a predetermined inner diameter again. ) Is formed, the outer diameter of the first horizontal portion 24 extending to a certain outer diameter, the first inclined portion 25, the outer diameter is extended at a predetermined angle, and at the end of the first inclined portion 25 again An adapter 2 composed of a second horizontal portion 26 that extends slightly to a certain outer diameter;

A rubber ring (3) inserted corresponding to the rubber ring mounting portion (22);

The inner diameter corresponds to the outer diameter of the tube 1 ', and the outer diameter is the same as the outer diameter of the extended end of the adapter 2 and the third horizontal portion 41 and the outer diameter is constant in the other direction of the adapter 2. It is composed of a second inclined portion 42 is reduced at an angle, protruding jaw protruded to compress the rubber ring (3) mounted on the inside corresponding to the coupling plate inserting portion 23 in the direction of the adapter (2) A coupling plate 4 composed of 43;

A cutting rib 52 is formed to have a cross section of a semicircle, and ends of both ends are extended in the direction of the center and the normal of the inner diameter and are formed by at least two or more coupling holes 51 to be coupled by the bolt 6 and the nut 7. And a fourth horizontal portion 53 into which the second horizontal portion 26 of the adapter 2 and the third horizontal portion 41 of the coupling plate 4 are inserted, which are formed at the center of the inner diameter, 4 and 3 and 4 inclined portions 54 and 55 corresponding to the first inclined portion 25 and the second inclined portion 42 on both sides of the horizontal portion 53, respectively. Outside the inclined portions 54, 55, two holders 5a, each consisting of fifth and sixth horizontal portions 56, 57 corresponding to the outer diameters of the first horizontal portion 24 and the tube 1 ', respectively, 5b) shows an integrated tube fastening to a holder using a coupling plate characterized in that it comprises a.

When explaining the principle of the present invention by the above-described configuration in more detail the pipe (1 ') of the tube inserting portion 21 of the adapter (2) equipped with the rubber ring (3) and the coupling plate (4) Push it all the way in.

At this time, the coupling plate 4 and the adapter 2 should be in a state where the gap is opened to some extent without being completely adhered by the rubber ring.

Thereafter, when the two holders 5a and 5b are coupled to tighten the bolt 6 and the nut 7 mounted on the coupling hole 51, the third inclined portions 54 and the fourth of the holders 5a and 5b are tightened. The first inclined portion 25 of the adapter 2 and the second inclined portion 42 of the coupling plate 4 slide along the inclined surface of the inclined portion 55, and consequently, the adapter 2 and the coupling plate. (4) will be in close contact.

The close contact between the adapter 2 and the coupling plate 4 gives pressure to the inner rubber ring 3 so that the rubber ring 3 has an inner diameter surface of the adapter 2 and an outer diameter of the tube 1 ′. The tight coupling between the two will act as a force to complete the connection of the two tubes.

In this fixed method, the conventional method of connecting both adapter parts is that the adapter is fused to both sides of the pipe, so that the manufacturing process is difficult and thus the unit cost is increased. Since it is possible to combine the manufacturing process and manufacturing cost will be reduced.

In addition, since the bolt 6 and the nut 7 to be combined are sufficiently combined with four in the conventional six or more, the joining process is somewhat simpler and easier to install than the method of tightening the bolt 6 formed along the circumference of the adapter. There is one advantage.

In addition, only by pushing the pipe (1 ') to be coupled to the pipe inserting portion 21, the pipe is primarily completed, the coupling and tightening of the holder (5a, 5b) is easier.

At this time, it is preferable to form an hexagonal insertion part in one of the corresponding coupling holes 51 to prevent the rotation of the bolt 6 or the nut 7 according to the shape of the bolt 6 or the nut 7. It may be replaced by various polygons.

4 is a perspective view showing a coupling plate according to another embodiment of the present invention, the surface in contact with the rubber ring 3 of the protruding jaw 43 constituting the coupling plate 4 has a plurality of irregularities on the surface An embodiment in which the formed emboss 44 is formed is illustrated.

When the emboss 44 is a simple surface on which the emboss 44 is not formed, the portion contacting and pressing the rubber ring 3 is biased to one side according to use, and is biased to the portion pressurizing the first rubber ring 3. There is a fear that the pressure is to be biased is an embodiment for preventing the distribution of even pressure and thereby increase the water tightness.

5 is a cross-sectional view according to another embodiment of the present invention, wherein at least one ring 31 having a predetermined thickness is further provided between the protruding jaw 43 of the coupling plate 4 and the rubber ring 3. An embodiment is shown.

This embodiment is formed to control the pressure acting on the rubber ring (3) by using the ring 31 as a thick or by inserting a plurality of thin ring 31 overlapping the rubber ring (3) to a higher pressure This is to deform and fix the tube 1 'more firmly.

This embodiment will be particularly useful when the rubber ring 3 used to replace only a part of the tube has weakened the force holding the tube 1 'with use.

6A and 6B are partial perspective views and cross-sectional views according to still another embodiment of the present invention, wherein the two holders 5a and 5b are inserted along the inner diameter of the sixth horizontal portion 57 to be inserted. A groove 58 is formed, and the reinforcing ring insertion groove 58 has shown an embodiment in which a reinforcing ring 59a of rubber material is inserted.

7 is a conceptual view according to another embodiment of the present invention, when the two holders 5a and 5b and the tube 1 'are coupled, the inner diameter of the sixth horizontal portion 57 and the tube ( An embodiment in which the rubber plate 59b is inserted between the outer diameters of 1 ') is shown.

In the above embodiment, when the pipe 1 'is fixed by only one rubber ring 3, the torsion pressure or a force in a direction other than the longitudinal direction is applied to the pipe 1' due to frequent changes in pressure. There is a risk of being damaged and leaking fluid or gas on the conduit, and there is a fear of lack of force to fix the tube (1 ').

Therefore, there is a need for an additional configuration in which a force for securing the pipe 1 'acts at a distance apart from the rubber ring 3.

Thus, the present inventors added the configuration of the reinforcing ring (59a) or rubber plate (59b) as described above to be more firmly coupled.

8 is a partial cross-sectional view according to another embodiment of the present invention, the second inclined portion 42 and the fourth inclined portion 55 is an embodiment in which the inclination angle is not formed the same.

In the above embodiment, the inclination angles of the second inclined portion 42 and the fourth inclined portion 55 are the same, so that the contact area increases.

This increase in the contact area may cause frictional force in the process of bringing the coupling plate 4 into close contact with the adapter 2 along the fourth inclined portion 55 and thus fail to compress the rubber ring 3 at a desired pressure. Since a problem that a lot of force is entered into the tightening of the bolt 6 is an embodiment for preventing this.

As described above, the present invention is easy to manufacture and reduce the manufacturing cost by providing a means that can be connected to the tube by welding the adapter only on one side without fusion to the adapter on both sides of the tube.

In addition, the pipe is primarily inserted into the adapter to combine the holder in a fixed state and to tighten the bolt and nut there is an effect that the construction is easy.

In addition, in order to maximize the watertightness is embossed on the coupling plate, and by additionally installing a reinforcing ring or rubber plate to prevent the flow of the combined pipe has the effect of minimizing the leakage of the connection.
