The present invention relates to a pipe connecting device, and more particularly to a pipe connecting device for connecting two pipes or pipes with each other so as to connect more simply and easily and not leak.

In general, to move water or other fluids from one place to another, the pipes or pipes must be moved through the interior space using pipes or pipes. Since it can not be produced indefinitely long, it must be limited to have a predetermined length. In a device that requires such a pipe or pipe, there is a need for successive use of multiple pipes or pipes to match the length required by the device.

Such a pipe and pipes or pipes and pipes related to the conventional metal tube connector connecting each other is disclosed in the Republic of Korea Patent Publication No. 20-1992-0000955, this conventional metal tube connector screw the connecting member and the metal tube body. In the constitution, the outer circumferential surface of one end of the metal tube body has an inner diameter slightly larger than the outer diameter thereof, and an externally-expanded fitting is inserted into the metal tube body by inserting a connector having a threaded portion and a fastening portion formed therein. After fixing to the inner diameter of the connector in close contact, it is characterized in that the fastening with a separate connecting member and a screw.

However, this conventional metal tube connector has the inconvenience of having to use a separate expander for fixing the metal tube and the connector, and also lacks a configuration to seal with a sealing member therein when the fluid flowing inside the tube to the outside of the connector when connected There was a risk of leakage. In addition, the conventional metal tube connector is a loss of elasticity due to the aging of the sealing member when used for a long period of time, there is a problem that the pipe and the connector is separated and separated when high water pressure is applied.

Therefore, in order to solve the above problems, the present invention can simply and easily connect between the pipe and the pipe or the pipe and the pipe without the need for a separate device, the pipe and the pipe heat connector is not separated and separated even at high water pressure, It is also intended to prevent leakage of air or fluid flowing inside the tube to the outside of the tube connection device when connected.

In order to achieve the above object, the present invention provides a pipe connecting device for connecting pipes capable of moving a fluid such as tap water, liquid, or air through the inner space, each of which forms a screw portion on both edges and fastening to one side, respectively. A joint body forming a plurality of face portions for facilitating fastening with a tool and having a protrusion in the center to receive the pipe on one side based on the protrusion; An elastic member installed on an outer surface of the pipe and in contact with both end surfaces of the joint body; A compression fixing member having a taper portion provided on an outer surface of the pipe and having a plurality of cutouts in which one surface of the elastic member is in contact and integrally formed therebetween, or separately inserted with an elastic member; A nut having a threaded portion corresponding to the screwed portion on one side and having an inclined surface on the other side capable of compressing the tapered portion of the crimping and holding member inward as it moves in one direction; A T-shaped member received on an opposite side of the pipe based on the protrusion of the joint body; And a nut having a thread corresponding to the thread of the pipe and accommodating a head of the T-shaped member and an elastic member in contact with the head of the T-shaped member in an internal space formed between the pipe by screwing in the thread. Characterized in that.

Here, the pressing fixing member has a body portion integral with the tapered portion, it is preferable that the groove portion is formed between the tapered portion and the body portion.

In addition, the pressing fixing member has a plurality of tapered portions and washers separated from the plurality of tapered portions, and an elastic member is inserted between the plurality of tapered portions, and is preferably attached with an adhesive.

In addition, the elastic members are preferably characterized in that each of the rubber.

On the other hand, in the pipe connecting device for connecting the pipes that can move the fluid, such as tap water, liquid or air through the inner space, to form a screw portion on each of the two edges for easy fastening with a fastening tool on each side A joint body forming a plurality of face portions and having a protrusion in the center to receive the pipe on one side based on the protrusion; An elastic member installed on an outer surface of the pipe and in contact with both end surfaces of the joint body; A nut having a screw portion corresponding to the screw portion on one side and having a plurality of protrusions connected on the other side via a recess; A cap having an upper cap and a lower cap forming a stopper portion which can be inserted into the recess, and wherein the upper and lower caps can be fixed and compressed by a bolt forming a bolt screw portion; A T-shaped member received on an opposite side of the pipe based on the protrusion of the joint body; And a nut having a thread corresponding to the thread of the pipe and accommodating a head of the T-shaped member and an elastic member in contact with the head of the T-shaped member in an internal space formed between the pipe by screwing in the thread. To; One of the upper cap and the lower cap has a stopper portion on one side so that the recess can be inserted into the recess, and the other one of the upper cap and the lower cap has a plurality of convex portions and recesses.

Here, the elastic member is preferably inserted between the lower surface of the upper cap and the upper surface of the lower cap.

In addition, the elastic member is preferably rubber.
