Socket for connecting pipe

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe connecting socket for connecting both ends of a pipe close to each other, and more particularly to a pipe connecting socket for connecting pipes to each other by inserting pipes into hollow portions formed at both ends of the socket.

Generally, in the case of constructing a pipe in a long section, since the length of the pipe is limited, both ends of the pipe are connected to each other to connect the pipes, and then the pipes are connected by bonding or welding.

Such a pipe connection method is well-leaked and very inefficient, and various methods have been tried to overcome this problem.

As a conventional technique for connecting pipes to each other, Japanese Patent Application Publication No. 10-0282510 discloses a method of connecting a connection pipe and a pipe connection port by extrapolating a connection pipe outside a pipe connection port having a groove on the outer circumference, The packing is extrapolated to the recessed portion formed around the outer periphery of the connecting port, the connecting pipe is extrapolated to the outside of the pipe connecting port where the packing is extruded, and the pressed groove is formed around the periphery of the outside of the connecting pipe, So that the fluid can be prevented from leaking on the connecting portion between the pipe connector and the connecting pipe.

Another prior art is a tube fitting for connecting a predetermined tubular body and a tubular body to a portion through which tubular tubular body is distributed through a predetermined type of tubing line in a Korean Utility Model Registration No. 0184256. The tubular tubular body has a connecting tube for fastening the one tubular body, A lower connecting body for connecting the upper connecting body to another tubular body by a fastening means; A receiving groove formed on the upper surface of the lower connecting member in a multistage manner and having a groove on an inner side surface of the lower connecting body; And a packing which is open at an upper portion of the receiving groove and has a protruding portion accommodated in the groove on a horizontal line of the outer diameter and has a built-in water inlet pipe formed on the inner and lower sides thereof. .

However, the above-mentioned prior art has a disadvantage in that the leaked water is well connected after the pipe connection or the connection structure is too complicated.

Accordingly, it is an object of the present invention to provide a pipe connecting socket which is simple in structure and easy to manufacture and fasten.

The pipe connection socket of the present invention is coupled to a hollow body having a hollow inside and a tightening cap for pressing and fixing one end of a pipe inserted into a socket at both ends of the body. The tightening cap has a ring shape, A plurality of elastic members for pressing the outer circumferential surface of the pipe inserted into the body of the socket are mounted so as to be spaced apart from each other in the circumferential direction.

As described above, since the pipe connecting socket of the present invention can separate the tightening cap directly pushing and pushing the pipe from the socket, it is easy to replace the pipe when the tightening cap is broken, and a remarkable effect .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a pipe connecting socket according to the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view of a pipe connecting socket according to the present invention.

As shown in FIG. 1, the socket 100 of the present invention is a socket 100 for fastening both ends of a nearby pipe 200 to each other. The socket 100 includes a hollow body 110, The tightening cap 120 is ring-shaped so that the inner surface of the tightening cap 120 is provided with a socket 100. The tightening cap 120 is fixed to the inner surface of the tightening cap 120, A plurality of elastic members 122 for pressing the outer circumferential surface of the pipe 200 to be inserted into the body 110 of the body 110 are spaced apart from one another in the circumferential direction.

That is, when the pipe 200 is inserted into the hollow portion formed at both ends of the socket 100, the socket 100 has a hollow tubular shape with a hollow interior, and when the pipe 100 is inserted into the fastening cap 120 fastened to both ends of the socket 100 The pipe 200 is pressed and fixed.

Fig. 2 is a perspective view of the fastening cap of the present invention, Fig. 3 is a plan view of the fastening cap of the present invention, Fig. 4 is a partial detail view of the fastening cap of the present invention, and Fig. 5 is a vertical cut-away view of the fastening cap of the present invention.

As shown in FIGS. 2 to 5, the tightening cap 120, which directly presses and urges the pipe 200, has a ring shape, and a screw thread is formed on the lower side of the inner surface, And is fastened to the screw thread.

Particularly, a groove 121 having a predetermined depth is formed on the inner surface of the tightening cap 120, and both sides of the groove 121 are inserted into the hinge coupling hole 122-3 of the elastic member 122 described later And a hinge shaft (not shown) serving as a pivot shaft is formed.

Therefore, the end of the elastic member 122, which is hinged to both sides of the groove 121 on both sides and rotates up and down, is protruded downward from the groove 121 inside the groove 121.

On the other hand, a locking protrusion 123 protruding outward is formed on the outer circumferential surface of the tightening cap 120 so that the hand does not slip when engaged with the body 110.

6 is a perspective view of an elastic member mounted on the tightening cap of the present invention.

’형상인 것이 특징이다.As shown in Fig. 6, the elastic member 122 has a front face '

However,

'Shape.

In other words, a hinge coupling hole 122-3 is formed in the longitudinal direction at the upper side of both sides of the body 122-1 of the plate shape, and the hinge coupling holes 122-3 are protruded from both sides of the groove 121 The formed hinge shaft is engaged.

In addition, a support piece 122-2 is formed in the central portion of the body 122-1, with three sides of the body 122-1 being incised,

Preferably, the incision surface is supported on both sides of the incised surface by cutting the upper and lower sides of the incised surface.

The reason why the pipe 200 is connected by the socket 100 of the present invention is that when the pipe 200 is inserted into the hollow portion formed at both ends of the socket 100, The elastic member 122 is inserted into the groove 121 while being pushed inward.

At this time, the pipe 200 is inserted by the elastic member 122, and a reaction force of a force pushing the elastic member 122 toward the inside of the groove 121 is applied.

That is, since the end portion of the support piece 122-2 is supported on the inner surface of the hole 121, the elastic member 122 has a force to push the outer surface of the pipe 200 to the center portion of the tightening cap 120 Since the elastic members 122 are mounted on the inner surface of the tightening cap 120 at regular intervals in the circumferential direction, the pipe 200 can be fixed with uniform force from all directions.

On the other hand, a spring can be additionally attached to the rear surface of the body 122-1 in order to supplement the pushing force of the support piece 122-2.

In addition, an elastic member 122 may be included in the hollow housing (not shown), and the housing may be configured to have a detachable engagement with the tightening cap 120 of the socket 100.

The connection of the socket 100 to and from the tightening cap 120 is such that a hollow is formed in the inner surface of the tightening cap 120 so that the housing can be inserted thereinto and a thread is formed on the outer surface of the tightening cap 120, So that the housing can be attached to and detached from the tightening cap 120 of the socket 100.

Alternatively, a tapered hollow hole may be formed so as to have a smaller diameter from the inside of the tightening cap 120 to the outside, and the housing may be formed so as to taper the outer circumferential surface corresponding to the tapered hollow hole, 120 of the housing.

The above-described method is economically very efficient because only the housing of the damaged part can be replaced without replacing the tightening cap 120 even if one elastic member 122 is broken.
