FIELD OF THE INVENTION The present invention relates to one-touch tubing connections, and more particularly to one-touch piping connections for mounting or detaching a solid pipe in one operation (one-touch).

In general, pipe piping is used as a path through which the fluid moves.

In particular, two or more pipes should be connected to be made in one path. When the material of the pipe is metal, the pipe is welded.

However, when the pipe joint is welded, it is a permanent joint that cannot be separated afterwards, which is very inconvenient for after-sales management, and also requires a skilled technician for construction and has a very complicated problem in the construction itself. .

In order to solve the above-mentioned problem, in recent years, a technique has been proposed that allows a pipe to be connected by a single operation of directly inserting a pipe into a socket.

Conventional one-touch piping connector is a configuration in which several accessories are inserted into the inner peripheral surface of the main socket (1) as shown in the accompanying drawings.

In more detail, the above-described various accessories are described as a stopper member (2), an O-ring member (3), a back ring (4), a locking claw (5), and an operating sleeve (6). ) And a collar ring (7).

That is, six accessories are sequentially inserted into the inner circumferential surface of the main socket 1, and an end portion of the main socket 1 forms a bending portion to prevent the collar ring 7 from randomly detaching.

The above-mentioned stopper member 2 has a first locking jaw 2a formed inside the inner diameter of the tubular body, a flange is formed outside the tubular body, and a protrusion 2b is formed on the outer surface of the tubular body.

In addition, the above-mentioned stopper member 2 is formed of a synthetic resin material having elasticity.

The O-ring member 3 described above is a material for keeping hermetic and hermetic.

The above-mentioned back ring 4 has a ring shape as a whole, but the inner diameter of the back ring 4 is narrow and the outer side has a wide tapered surface, and a second locking jaw is formed on the outer side.

In the above-described locking-claw 5, a plurality of elastic pieces 5a are formed inwardly inclined inwardly inward toward the inner side of the main socket 1.

When an external pressure is applied to the elastic piece 5a from the outside to the inward direction, the edge of the elastic piece 5a is opened, and when the external force is removed, the edge is lifted in the center direction by the restoring force of the elastic piece 5a.

The operation sleeve 6 described above is formed with a third locking jaw 6b on the outer surface of the second tube body 6a.

The collar ring 7 described above is formed with a fourth locking jaw 7a on the inner circumferential surface.

Hereinafter, the operation of the conventional one-touch piping connector will be described.

The stopper member 2 and the O-ring member 3 are sequentially inserted into the first expansion pipe 1b of the main socket 1, and the back ring 4 is inserted into the second expansion pipe 1c of the main socket 1. ), The locking-claw 5, the actuating sleeve 6 and the collar ring 7 are inserted.

The stopper member 2 described above is in close contact with the inclined portion formed between the base pipe portion 1a and the first expansion pipe portion 1b with the projection 2b formed on the outer surface thereof, so that the stopper member 2 is connected to the main socket 1. It is no longer inserted into its depth.

The O-ring member 3 described above is disposed between the stopper member 2 and the back ring 4.

The back ring 4 described above is in close contact with the inclined portion formed between the first expansion pipe 1b and the second expansion pipe 1c and does not enter more than a predetermined depth of the main socket 1.

The locking-claw 5 described above touches the back ring 4 described above, and the elastic piece 5a is located in the tapered surface of the back ring 4.

The operating sleeve 6 described above is arranged between the locking-claw 5 and the collar ring 7 described above, in particular the third locking jaw 6b is hooked on the fourth locking jaw 7a so that the operating sleeve 6 ) Is not arbitrarily separated / detached from the main socket 1.

In addition, an end portion of the second expansion pipe 1c of the main socket 1 is bent outside the collar ring 7 to form a banding portion, and the banding portion prevents the collar ring 7 from being detached from any position.

The pipe for pipe is inserted through the inner diameter of the working sleeve 6, and the end of the pipe is caught by the first locking jaw 2a of the stopper member 2 so as not to be inserted further.

In addition, the O-ring member 3 is in close contact with the outer surface of the tube to maintain airtightness.

In addition, the elastic piece 5a of the locking-claw 5 is pressed into the outer surface of the tubular body so as to be pressed to the outer surface of the tubular body so as not to retreat.

In other words, the pipe is piped by a single operation of inserting the pipe into the main socket 1.

In addition, when removing the pipe | tube P, the operation sleeve 6 is pressed in the inner direction of the main socket 1.

At this time, the operation sleeve 6 pushes the surface of the elastic piece 5a described above so that the edge of the elastic piece 5a is opened from the outer surface of the tube.

In other words, the tube is retracted and separated in the state where the elastic piece 5a of the locking-claw 5 is opened.

However, when pressing the operation sleeve 6 described above, the outer end surface of the operation sleeve 6 must be pushed. In this case, the outer end surface can be pressurized only by using a dedicated tool because the surface area exposed is very narrow.

In other words, in order to dismantle the pipe (P) made of piping, it is inconvenient to use a separate dedicated tool, and in particular, there is a problem that must carry a dedicated tool, the pipe (P) in the state that the dedicated tool is not provided There is a problem that can not be disassembled at all.

On the other hand, the conventional one-touch piping connector has the inconvenience of dealing with six parts inserted into the main socket as a necessary accessory.

Therefore, the technical problem to be achieved by the present invention is to assemble the accessories to be inserted into the main socket in advance in the assembly of the one-touch piping connector in order to increase the efficiency of assembly fixing, and also when dismantling the pipe Its purpose is to provide a one-touch piping connection that can improve convenience by eliminating the need for special tools.
