Figure 2 is a perspective view of the pipe connecting device for preventing leakage and strengthening the coupling force according to an embodiment of the present invention.

Figure 3 is a perspective view of a pipe connecting device for preventing leakage and strengthening the coupling force according to another embodiment of the present invention.

As shown in Figure 2, the pipe connection device 100 for leak prevention and bonding strength of the present invention,

In a pipe connecting device which is joined together to fix two butt ends of each other,

A band 110 surrounding the two tubes 200 facing each other;

A support plate (120) attached to both sides of the band and forming a fastening hole to allow the fastening means to pass therethrough;

A fastening means for fastening with a nut 150 to fix the bolts 140 inserted into each other through fastening holes formed in the support plate;

And an auxiliary member 160 for preventing the band from being pushed up by the opposing forces applied to the two support plates when the band is coupled to the butt body.

Tube connection device of the present invention consists of four parts, the band, the support plate is attached to both sides of the band, the fastening means for fastening the respective support plate, the band is pushed up when the band is coupled to the tubular body It consists of an auxiliary member to prevent.

The band has a length relatively longer than the outer circumferential surface length of the tubular body 200 to be connected, and the width thereof is such that it can wrap both tubular bodies 200 to be connected to a suitable length, and is made of a metal material having a predetermined thickness.

The support plate is coupled to both sides of the band, wherein the support plate is also made of a metal material can be attached by rivets or welding.

And the fastening means is composed of a long bolt 140 and a nut 150 to be fastened through each support plate.

The auxiliary member 160 is an auxiliary member configured to prevent the band of the corresponding part from being pushed upward by the opposite force applied to each support plate when the band is coupled to the butt tube, the conventional pipe connecting device In this case, the stronger the band is connected to the tubular body, the larger the gap between the band and the tubular body is, which causes leakage, which is not the end of the band meets, but one end is extended into the other end of the tubular body. Since the enveloping means is coupled to the fastening means, the pressing part is pushed up by the fastening means as it is, or even the pipe connecting device is rotated, and the watertight member of the rubber material that primarily surrounds the pipe is a band. There is a problem that is torn by the end of the extended portion of the. This is because the bending force of the extending portion and the bending of the band is the same when the fastening force is fastened by the coupling means.

Thus, by attaching the auxiliary member independent of the band with a certain width by the coupling means to remove the phenomenon that the band rises during the coupling.

At this time, one of the two ends of the band of the present invention is not extended to constitute, but is configured so that both ends abut.

On the other hand, the auxiliary member is processed to have a coarse surface of the tubular side may be configured not to move when coupled through the fastening means.

In addition, the bending of the auxiliary member is formed to be different from the bending of the band in order to further strengthen the adhesion, that is to say that the portion of the spherical diameter larger than the diameter of the band as the conventional bending is the same or the pipe connection is pulled out or turned The phenomenon can be eliminated.

And, the width of the auxiliary member is configured to have between 1/4 to 1/6 of the width of the band, but the height is configured to be the same.

As shown in Figure 3, according to another embodiment of the present invention is configured to include a water-tight member 170 surrounding the butt portion of the tube for preventing leakage and strengthening the binding force.

Through the watertight member, it is possible to secondaryly prevent the bonding force and the deformation of the band to the auxiliary member, to form a protrusion 171 formed in parallel at regular intervals along the circumferential surface of the inner wall for strengthening the bonding force. .

At this time, as shown in Figure 6, the protrusion is formed to be inclined in the direction in which the tube is inserted is characterized in that the tube can be inserted firmly.

In other words, when two tubes are inserted into the pipe connecting device, the tubes may be inclined in the direction in which the tubes are inserted. However, when the tubes are inserted, the tubes may be inserted more easily. It does not have the characteristics.

As shown in Figure 4, the support plate according to another embodiment of the present invention,

A groove 180 is formed between the fastening means and the fastening means to prevent a decrease in the coupling force generated when deformation of the tubular body occurs.

It has the shape has the advantage that can be more firmly adhered by the elastic restoring force.

Hereinafter, with reference to the accompanying drawings with respect to the fastening of the pipe connection device according to the present invention will be described in detail.

FIG. 5 is a conceptual view sequentially illustrating the coupling of the pipe connection device of the present invention according to FIG. 2.

After wrapping the band between the two tubular body 200 and inserting the auxiliary member between the band and the tubular body through the long bolt through the support plate and fixed with a nut.

When the nut is tightened, each support plate comes close to each other, which causes the band to squeeze the tubular body, and the pressure is further exerted by the auxiliary member. As the pressure is applied, the bending of the auxiliary member becomes more gentle and strengthens the bonding force. When the watertight member is configured between the auxiliary member and the tube body, the watertight member can be introduced into the end portion of the auxiliary member to prevent the tearing phenomenon.
