1 is an exploded perspective view showing an example of a pipe connection socket according to the present invention, Figure 2 is a cross-sectional view showing a state of connecting the pipe using the pipe connection socket shown in Figure 1, Figure 3 4 is an exploded perspective view showing another example of the pipe connection socket according to the invention, Figure 4 is a cross-sectional view showing a state of connecting the pipe using the pipe connection socket shown in Figure 3, Figure 5 according to the present invention 6 is an enlarged cross-sectional view of an example of a packing installed in a socket for connection, and FIG. 6 is an enlarged cross-sectional view of another example of a packing installed in a socket for connecting a pipe according to the present invention.

As shown, the socket for pipe connection according to the present invention is an adapter (1); A packing 2 inserted into and installed in the adapter 1; It consists of a holder (3) for pressing and fixing the end of the packing (2).

The adapter 1 is a cylindrical cylindrical body in which one end of the tube 100 is inserted and inserted into the inner circumferential surface of one end thereof, and a packing locking groove 11 is formed to hold the packing, and an inner circumferential surface of the end of the packing locking groove 11 is formed. Accordingly, the holder insertion groove 14 is formed.

Such an adapter 1 may heat-seat the tube 100 at one end as shown in FIGS. 1 and 2 of the tube 100.

In addition, the adapter 1, as shown in Figures 3 and 4, may be formed by forming the packing engaging groove 11 and the holder insertion groove 14 at both ends symmetrically around the stop portion. .

Thus, when the packing engaging grooves 11 and the holder insertion grooves 14 are formed at both ends of the adapter 1, the pipe 100 is fitted to both sides around the middle of the adapter 1 and is fixed and the pipe 100 ) And the holder 3 are used as a means for fixing the two ends of the adapter 1.

Of course, when the adapter 1 is formed in a single-piece type, that is, even when the tube 100 is formed to be heat-sealed on one side, the packing 2 and the holder as a means for connecting the other tube 100. (3) is used.

In order to heat-weld the adapter 1 to the tube 100 as described above, a heat-sealed wing that is heat-sealed to one end of the tube 100 at an end opposite to the end where the holder insertion groove 14 of the adapter 1 is formed. (15) is further formed.

The heat-sealed wing 15 is formed by forming a wing on the inner circumferential surface of the adapter 1 as shown in Figs. 1 and 2 and the width of the wing is formed to the thickness of the tube 100.

In addition, as shown in FIGS. 1 and 2, a small wedge 1a is formed on the inner circumferential surface of the adapter 1 so as to be in close contact with the outer circumferential surface of the packing 2 and cause friction. The packing 2 is sandwiched between the tube 100 inserted into the packing 2 so that the tube 100 is not separated from the adapter 1.

In addition, the locking groove 1b may be formed on the inner circumferential surface of the adapter 1 in place of the wedge 1a.

One or more locking grooves 1b are formed on the inner circumferential surface of the adapter 1, and the locking jaws 2b are formed on the opposite parts of the packing 2 so that the packing 2 may be fixed inside the adapter 1. You can do that.

In addition, on the outer circumferential surface of the adapter 1, the adapter 1 is further prevented from rotating in the circumferential direction, and the anti-rotation protrusion 17 to which the connection tool is applied when connecting with the tube 100 is further formed. When the adapter 1 is formed in a cylindrical shape and is thus formed in a cylindrical shape, the adapter 1 may be rolled and moved during the operation, so that the operation may be difficult. In order to compensate for this disadvantage, the above-described anti-rotation protrusion 17 is formed at the interruption of the outer circumferential surface as shown in FIG.

In addition, the anti-rotation protrusion 17 should pull the tube 100 toward the adapter 1 side when the tube 100 is connected, and at this time pull one side of the traction means for pulling the tube 100 toward the adapter 1 side. The role of fixing Can be.

As described above, the means for fixing the tube 100 to the adapter 1 is the packing (2) and the holder (3) is a single type or a positive type to have the same structure as described only one, and will be described by adding only the part that is different.

The packing 2 has a circular cylindrical shape inserted into the adapter 1 and is formed with a pressing protrusion 23 in a circular shape along an outer circumferential surface, and a packing formed at an end of the adapter 1 on an outer circumferential surface of one end portion. A locking jaw 21 that is caught by the locking groove 11 is formed.

As described above, the packing 2 is fixed to the inner circumferential surface of the adapter 1 so that the friction force between the outer circumferential surface and the inner circumferential surface of the adapter 1 must be large in order to strengthen the coupling with the adapter 1. As described above, a plurality of fine wedges 1a should be formed on the inner circumferential surface of the adapter 1, and a structure opposite to the outer circumferential surface of the packing 2 should be formed.

However, when the fine wedge (1a) is formed on the inner peripheral surface of the adapter (1), the wedge (1a) is caught on the outer peripheral surface of the packing (2) Since it is not separated from the adapter 1, it is not necessary to form a fixed structure.

As described above, the packing 2 inserted into the inner circumference of the adapter 1 has an end portion of the tube 100 inserted therein, and the pressure protrusion 23 formed with the inserted tube 100 on the outer circumferential surface of the packing 2. By pressing them, the packing is pressed between the adapter 1 and the tube 100 so that the tube 100 is not separated from the adapter 1.

In this case, when a force is applied from the outside, the packing 2 may come out of the adapter 1 and the holder 3 may be installed in the holder insertion groove 14 formed at the end of the adapter 1 to prevent this.

The holder 3 has a tapered shape on the inner circumferential surface of the end facing outward in a circular ring shape, so that the end of the pipe 100 is easily guided and moved toward the packing 2 side. Made it possible.

In addition, the pressing protrusion 23 formed on the outer circumferential surface of the packing 2 may be sharply pointed toward the middle of the adapter 1 shown in FIGS. 5 and 6. By forming the pressure protrusions 23 in this manner, the pipe 100 is easily inserted into the adapter 1, but when pulled out, the pipe 100 can be prevented from coming out so that the connection of the pipe 100 can be more warned. .

In order to reinforce the strength of the protrusions, the sharpened pressure protrusions 23 further include a reinforcement part 23a as shown in FIG. 6 between the pressure protrusions 23 and the inner circumferential surface of the packing 2.

The pipe connection socket of the present invention configured as described above is heat-sealed at one end of the pipe 100 as shown in FIG. 1 and FIG. 2, or is made in a long shape as shown in FIGS. 3 and 4. Pipes 100 may be connected to each of the packings 2 by installing them.

As shown in FIGS. 3 and 4, when the tube 100 is inserted and fixed to both sides, the fixing blade 16 is formed on the inner circumferential surface of the adapter 1, and the packing 2 is formed. A fixing groove 26 is formed on the outer circumferential surface so that the stop portion of the packing 2 can be fixed to the stop of the adapter 1.

In addition, in the case of forming the janggu shape as described above, the direction in which the pressing protrusions 23 formed on the packing 2 protrude is preferably formed to be inclined to face the middle part so as to face each other, and the stopping part of the packing 2 is formed. The inner diameter of the tube 100 is formed to be smaller than the inner diameter of the tube 100 to prevent the water from entering the profile in the case of a multi-layer tube made by winding the profile of the small tube.

That is, the entire end of the tube 100 is covered by the packing 2 to prevent water from entering the profile constituting the multilayer tube.

Although obvious, the adapter 1 and the holder 3 are made of a material having excellent strength such as synthetic resin or metal, and the packing 2 is made of a material having elasticity such as rubber or synthetic resin.

Hereinafter, the pipe provided with the socket comprised as mentioned above is demonstrated.

The pipe 100 having a pipe connection socket according to the present invention is further provided with a pipe connection socket at one end.

The pipe connection socket is configured as described above and a detailed description thereof will be omitted.

However, only the structure or method of connecting the pipe for connection with the pipe 100 will be described in detail.

First, as shown in FIGS. 1 and 2, when the pipe connection socket is integrally installed at one end of the pipe 100, the pipe connection socket and the pipe 100 are heat-sealed, and the other pipe 100 is connected. It is inserted into the adapter 1 and connected.

As described above, when manufacturing a single-piece pipe in which a pipe connecting socket is connected to one side of the pipe 100 and integrated, the heating plate is placed between the pipe 100 and the pipe connecting socket so that the pipe 100 and the pipe connecting socket face each other. After heating the parts to melt them, they may be pressurized with each other to heat butt. The method for thermally fusion of the pipe and the socket for pipe connection is a commonly known technique, and a detailed description thereof will be omitted.

When the socket for the pipe connection of the present invention is formed in the elongated shape as shown in Fig. 2 and 4, all the process of connecting the pipe 100 can be carried out in the site of the pore, the process of connecting the pipe is as follows.

First, the packing 2 is inserted into the adapter 1 so that the locking jaw 21 formed at both ends of the packing 2 is caught by the locking groove 11 formed at both ends of the adapter 1.

As such, the packing 2 is pushed into the tube 100 from one end in a state where the packing 2 is installed inside the adapter 1 to sufficiently push the tube 00 to the middle portion of the adapter 1.

At this time, the pressing protrusion 23 formed on the outer circumferential surface of the packing 2 becomes pressurized by the outer wall of the tube 100 and is in a distorted state, while being closely adhered to the outer circumferential surface of the tube 100 to hold the tube 100 to warn.

That is, the tube 100 is reversed in the packing 2, and the pressure protrusions 23 are distorted to press the outer circumferential surface of the tube 100 to fix the tube 100 to the inside of the adapter 1.

At this time, in order to sufficiently push the tube 100 into the inside of the adapter 1, the end of the adapter 1 or the tube 100 is knocked or pushed with a predetermined mechanism or device.

In this state in which the adapter 1 is coupled to the tube 100, the other tube 100 is fixed to the other end of the adapter 1.

At this time, the end of the tube 100 is aligned with the end of the packing (2) installed in the adapter (1) and then tapping the end of the tube 100 so that the tube 100 is deeply inserted until the interruption of the adapter (1).

After the packing 2 is installed in the adapter 1 in the above process, the holder 3 is installed in the holder insertion groove 14 formed at the end of the adapter 1 so that the end of the tube 100 is connected to the holder ( It is possible to easily guide the inside of the packing by the inclined surface 31 formed in the 3), and after the tube 100 is sufficiently inserted into the adapter 1 as shown in FIG. It is possible to fix the holder 3 by passing the fixing screw 4 to the end of the adapter 1 through the.

While the invention has been described with reference to the preferred embodiments, many modifications and variations are possible without departing from the scope and spirit of the invention as set forth by the claims below.

As described in detail above, in the present invention, the packing is installed inside the adapter and the pipe is press-fitted therein to connect the pipe and the pipe, so that the packing is not separated from the adapter to form the unevenness or wedge and packing with the holder. Effortlessly time to tighten the fixing bolts by not using a fixing bolt, because it can be easily fused to the end of the tube by combining the fixed or by inserting the end of the tube into the adapter to join the tube and the tube. Since it can reduce the work time, there is an effect that can shorten the working time.

In addition, since the socket is detachably configured, there is an effect of preventing the socket from being changed by the load when the pipe is loaded.

While the present invention has been described with reference to the accompanying drawings, it will be apparent to those skilled in the art that many various obvious modifications are possible without departing from the scope of the invention from this description. Accordingly, the invention can only be construed limited by the words of the appended claims.
