On the outer circumferential surface of the cap 38, a plurality of non-slip grooves 42 are arranged at equal intervals. A rubber packing 46 interposed in the large diameter 32 of the body 34 is provided, and a plurality of elastic pieces 48 inclined to one side are arranged on the inner circumferential surface of the rubber packing 46 at an equal interval, and the outer side thereof. As a part of the cap is in contact with the inner surface of the cap has a predetermined height and is provided with a protrusion 49 having a step so that the first contact with the protrusion 49 when the cap is fastened.

A state in which the pipe pipes are connected and fixed to each other by the pipe pipe connector configured as described above and the effects thereof will be described.

First, in a state where the rubber packing 46 is positioned at the large diameter 32 formed in the body 34, the cap 38 is engaged with the threads formed on the inner circumferential surface of the cap 38 and the threads formed on the outer circumferential surface of the large diameter 32. ) Rotate in one direction. When the cap 38 is rotated in one direction, the cap 38 has a state in which the cap 38 is coupled to one free end of the body 34 by screwing. At this time, since the protrusion 49 is provided on the outer surface of the rubber packing 46, the rubber packing 46 is in close contact with the body 34 due to the thickness of the protrusion 49.

When the cap 38 is fixed to one free end of the body 34 by screwing, one free end of the pipe pipe 44 is temporarily fastened to the through hole 40 of the cap 38. In the pipe pipe 44 is inserted into the attraction force or hitting the other side of the pipe pipe 44 using a hammer such as a hammer. At this time, the pipe pipe 44 passes through the through hole 40 of the cap 38 by the impact of being inserted or hit by the attraction force and pushes the inclined elastic piece 48 formed in the rubber packing 46 It has a state fixed to the small diameter 31.

The piping pipe 44 is inserted into the small diameter 31 by the manpower or the impact to be impacted and stopped by contacting the partition plate 36, and a plurality of elastic pieces arranged at equal intervals on the inner circumferential surface of the rubber packing 46 pushed in The 48 is tightly fixed to the outer circumferential surface of the pipe pipe 44 by the elastic force and the restoring force. That is, since the elastic piece 48 protrudes inwardly inclined in the direction in which the pipe pipe 44 enters, when the pipe pipe 44 is tightly fixed to the small diameter 31, the elastic piece 48 is formed by the elastic force and the restoring force. ) Is tightly fixed to the outer circumferential surface of the pipe pipe 44 so as not to be separated in the opposite direction inserted. In addition, since the pipe pipes 44 are connected and fixed to each other by the body 34 by inserting by manpower or hitting, the worker does not need to tighten the cap 38 again after the worker loosens the pipe 38 as in the related art. Not only can 44 be interconnected, but also workability and productivity are improved.

Figure 5 is an enlarged cross-sectional view showing the main portion showing another embodiment according to the present invention. As shown in FIG. 5, a coupling protrusion 50 formed at one side of the free end of the body 34 to be inclined outwardly (tilt a) is protruded, and the body 34 is formed on the outer circumferential surface of the rubber packing 46. A fastening groove 52 is formed in which the engaging protrusion 50 is inserted into and fixed. A coupling groove 54 into which the rubber packing 46 is inserted is formed on the inner circumferential surface of the cap 38, but one side is inclined outward. (Inclined b), the pipe pipe can be fixed more tightly to increase the sealing effect, and can be prevented from being pushed in the opposite direction to the direction in which the pipe pipe is inserted by the pressure of the fluid flowing into the pipe pipe. will be. That is, when the pipe pipe is inserted, the elastic piece 48 is in close contact with the outer circumferential surface of the pipe pipe and is pushed in like the pipe pipe. At this time, the rubber packing 46 is subjected to resistance by the portion contacting the inclined a and the coupling groove. Since the rubber packing 46 is interrupted by the rubber packing 46 interposed therebetween, the rubber packing 46 may be deformed or dislodged, thereby preventing the adhesive force from being impaired, and the pipe pipe is completely inserted into the fluid pipe. In the case of flowing, the pipe is subjected to a force in the opposite direction from the one inserted, and then subjected to resistance by the rubber packing 46 interposed in the surface contact by the inclined b formed in the cap 38 and the coupling groove 54. Therefore, the deformation or separation of the rubber packing 46 is reduced, so that the adhesion between the elastic piece 48 and the pipe pipe is increased, thereby increasing the sealing effect. On the other hand, when time passes after the pipe pipes are connected to each other, the rubber packing 46 is compressed to each contact surface, thereby achieving a higher sealing effect. When the 46 is removed, if a part of the rubber packing 46 that is inclined tightly by the inclination a is pressed, the rubber packing 46 that is in close contact may be easily removed, and thus repair or repair may be easily performed.

6 is an enlarged cross-sectional view showing another embodiment according to the present invention is an embodiment in which the shape of the rubber packing 46 and the shape of the cap 38 is changed. As shown in Figure 6, the outer circumferential surface of the rubber packing 46, both sides from the top to the lower side of the wing piece 56 inclined inwardly toward the configuration is configured to escape or deform the rubber packing 46 during insertion of the pipe pipe To prevent the, one side of the free end of the body 34 is formed to be inclined so as to be in close contact with one surface of the wing piece 56 of the rubber packing 46, the wing piece of the rubber packing 46 on one side of the cap 38 (56) A support piece 58 having an elastic force for supporting the elastic piece 48 of the rubber packing 46 in a state of being in close contact with one surface is formed, and the same inclination a and inclination b as illustrated in FIG. 5 are formed. Since it is possible to increase the adhesion effect as well as to prevent the elastic piece 48 is deformed to the outside. That is, when the pipe pipe is inserted, the elastic piece 48 is in close contact with the outer circumferential surface of the pipe pipe and is pushed in like the pipe pipe. At this time, the rubber packing 46 is subjected to resistance by the surface contacting the inclined a and is also inclined. Since the resistance is received by the wing piece 56, the rubber packing 46 can be prevented from being deformed or departed, thereby impairing the adhesion. When the pipe pipe is completely inserted and fluid flows into the pipe pipe, the pipe pipe is inserted. At this time, when the force is received in the opposite direction from the previous one, the surface contact by the inclined b formed on the cap 38 and the wing piece 56 reduce or deform the rubber packing 46 and also the cap 38 is formed. Since the elastic piece 48 is supported by the support piece 58, the adhesive force between the elastic piece 48 and the pipe pipe is increased, thereby improving the sealing effect. On the other hand, when the time elapses after the interconnection by inserting the pipe pipes and the same operation as the embodiment of FIG. 5, the rubber packing 46 is compressed to each contact surface, thereby achieving a higher sealing effect, the inserted pipe When the rubber packing 46 is removed during repair or repair of the pipe, if a part of the rubber packing 46 that is tightly inclined by the inclination a is applied, the rubber packing 46 that is in close contact can be easily separated. Or repair can be made easily.

FIG. 7 illustrates a right side surface of the cap 38 shown in FIG. 6, wherein the support piece 58 is formed along the inner diameter of the cap 38, but is easily moved even if the pipe is pushed in when the pipe is inserted. When the pipe does not interfere with the insertion and when the force is applied in a direction opposite to the direction in which the inserted pipe is inserted by the pressure of the fluid is to form a rocking groove (60) on the outer surface so that the bearing force can occur. The support piece 58 is a cutting groove 62 at regular intervals along the inner diameter of the cap 38 so that the support piece 58 does not break or crack even when the pipe pipe is inserted or moved after being inserted. You can also add the one you have prepared.

8 is a partially enlarged cross-sectional view of another embodiment of an elastic piece of the rubber packing of the present invention, and is another embodiment of the elastic piece 48 of the rubber packing 46 shown in FIGS. 4, 5, and 6, and connects a pipe pipe. In order to facilitate the insertion of the pipe pipe when the pipe pipe is inserted into the connector 30, the inner diameters of the elastic pieces 48a, 48b, and 48c are different, that is, they are elastic when viewed from the center of the rubber packing 46. As the inner diameter decreases by the length 'd' from the piece 48a to the elastic piece 48c, the initial diameter of the pipe pipe can be entered from the elastic piece 48a having the large inner diameter to the elastic piece 48c having the small inner diameter. The friction between the outer circumferential surface of the pipe pipe and the ends of the elastic pieces 48a, 48b, and 48c is gradually increased. In addition, the shape of the elastic piece (48a, 48b, 48c) is formed so as to have a linear inclination rather than a curved type, the inclination difference so that the inclination angle of the ends of the elastic piece (48a, 48b, 48c) and the other parts are different (Incline c) is formed so that when the pipe pipe is inserted, the end of the thin elastic pieces (48a, 48b, 48c) is pushed in so that the pipe pipe is inserted into the body 34 of the present invention with a small force. If you want to escape in the direction opposite to the direction to be inserted so as to receive a resistance of the thick portion is configured so that the separation is not easy.

As described above, the connector of the pipe pipe according to the present invention is arranged on the inner circumferential surface of the rubber packing in contact with the pipe pipe at equal intervals, and by providing an elastic piece inclined to one side, the pipe pipe is simply inserted by manpower or by a rubber hammer. Piping pipes can be easily interconnected by hitting, eliminating the need to open and close caps to fasten the pipes, and pipes and bodies can be easily interconnected and fixed, so there is no waste of manpower or mechanical force. Since the pipes are interconnected to each other, the workability and productivity can be improved. The coupling protrusions are formed on the body of the pipe pipe connector, and the rubber packing forms the coupling grooves fixed to the coupling protrusions. Piping wave by forming a coupling groove where rubber packing is tightly fixed When inserting the pipe, even if the elastic piece that is in close contact with the outer circumferential surface of the pipe pipe is pushed in, the rubber packing is not deformed or separated, so that the pipe pipe and the rubber packing are in close contact with each other. It improves the bearing capacity of rubber packing to more closely fix the connected pipe pipe to prevent the separation and improve the sealing force. Since the rubber packing and the body are made of inclined surfaces, it is crimped when repairing or repairing. There is an effect that can be easily released rubber packing. In addition, the inclination of the straight line forming the elastic piece is different, and the inner diameter at the center of the rubber packing is changed to facilitate the insertion of the pipe pipe, and thus the pipe pipe is not easily separated.
