Description

One-Touch Pipe Connection}

The present invention relates to a pipe connection structure, in particular fixed using cushioning. The present invention relates to a pipe connecting structure that can easily separate two connected pipes and to easily connect copper and plastic pipes.

Since the connection of two or more pipes is essential when piping a pipe for transporting a fluid, it must be connected easily and fastly and securely. Various pipe connection methods and structures have been devised and used, and one of the most widely used plastic pipes is a sealing 14 and a washer 13 as shown in FIG. ) (Washer), to form a ring-shaped connection cap (3) provided with a fixing ring (21) and fixed to prevent the pipe from being released by inserting one end of the pipe into the insertion hole (18) of the connection cap. To connect. This will be described in detail as follows.

First, the connection cap 17 is a hollow cylinder (cylinder), one end is screwed to the base body 11, the other end is formed with an insertion hole 18 so that one side of the pipe can be inserted snugly. And, the insertion port is slightly protruded to the inner side 16 of the connection cap.

And the sealing 15 is two pipe connection. To maintain airtightness during fixation, a known o-ring, usually made of rubber, is used.

One side of the washer 13 is formed flat as a known washer, and the other side is formed in the center of the tapered portion 20 so that it can be placed in the fixing ring 21 formed with the radial piece 12.

On the other hand, the fixing ring 21 is called a grab-ring (gravure-ring), the inside of the ring is formed a plurality of fixed radiation piece 12 is bent inward more than a vertical angle, all the radial piece at a predetermined angle As it is bent, it is tapered to form a "v" shape and looks like an angle.

Pipe connecting structure consisting of the above components is inserted into the fixing ring 21 so that the radial piece 13 is bent to the inside of the pipe bent to the step (22) formed inside the base 11, the tapered portion ( When the washer 13 is inserted so that the 20 faces the same direction as the radial piece 13 of the fixing ring 21, and after that, the connecting cap 17 is screwed into the sealing ring 14. The above elements are fixed.

When the pipe is connected, the tip of the pipe is inserted while pushing the radial piece of the fixing ring 21 slightly, and the radial piece 12 is deformed below the plastic strain point, and the outer surface of the pipe is pressed by the elastic restoring force. When the insertion of the pipe is completed, since the radial piece 13 of the fixing ring 21 presses the outer surface of the pipe with a strong elastic restoring force, the radial piece 13 slightly penetrates the outer surface of the pipe by the force, The two pipes are firmly connected to each other and cannot be easily removed by reverse external forces.

Such a pipe connection structure is a connection structure that is very widely used because of its advantages in that its structure and components are simple, easy to manufacture, excellent in airtightness, and above all, easy to connect pipes and are not easily separated from external forces.

However, such a connection structure has a high risk of leakage when the pipe is not horizontal when fastened, and there is a difficulty in the insertion of the pipe due to a problem in the radial piece structure of the fixing ring 21, and its corrective work is not easy. Once the pipe is inserted, it cannot be pulled out again in the reverse direction of the radial piece 13, so if the pipe needs to be separated for work such as repair or maintenance, there is no other device for separation, which destroys the connection cap 17 or breaks the pipe. Had to cut.

This pipe connection structure has been widely used with the above advantages, but it is difficult to calibrate during the pipe connection work, and for replacing some pipes, it is necessary to destroy other pipes that can be used for a long time, or replace existing pipes. The problem of large economic loss due to unnecessary pipe material replacement work, such as the need to destroy the cap and refit the new connection cap.

Although the present invention in FIG. 2 improves the performance of the product by supplementing many of the existing problems than those shown in FIG. 1, there are some problems.

This is explained as follows.

A point ending at the tapered portion 7 of the inner diameter small cat 8 forms a vertex.

When pipe bending occurs after inserting the pipe, the outer diameter small cat (6) should fix the inner small cat tightly. When dismantling after joining pipes with structural problems, it was difficult to disassemble with bare hands, so it was necessary to use a special tool devised by the product manufacturer.

Thus, although the product has advanced in terms of performance, convenience has led to the need for improvement.

The present invention was devised to solve the above problems, and it is easy to calibrate the pipe connection by introducing a tension washer with spring function and cushioning and applying a mechanical mechanism that can suppress the flow of the inner diameter small cat. It is an object of the present invention to provide a pipe connection structure that can easily separate a pipe without a tool or a tool, and to facilitate the connection and disassembly of copper pipe and plastic pipe.

The present invention for achieving the above object, the internal parts of the connector in order to be seated in the O-ring, sleeve, tension washer, inner diameter small cat, outer diameter small cat and the bending process through plastic deformation to the base body to fix the component In the configuration to assemble the cushioning designed to be detachable after rough

It is a universal feature that it can be completely fixed and connected by pushing the pipe by forming a pipe insertion hole in the hollow inner diameter cat, but it is a component that can be disassembled by hand without any tools or disassembly tools. When removed, it has a feature that makes it easy to disassemble by using a tool and a double bearing structure to suppress the flow of the pipe as much as possible.

The present invention having the above-described configuration is easy to calibrate when connecting pipes, and even after completion of the connection, the connected pipes can be easily separated by hand without any tools or tools, so it is economical when repairing and repairing in narrow spaces, and copper pipes and plastics It has the effect of presenting a breakthrough connection structure of the series pipe customs.

The present invention is a core element of the conventional pipe connection structure, as shown in Figures 3 and 4 as the inner diameter of the outer diameter small cat 29 is formed a stage (40) different from the inner diameter small cat 31 The other end 37 is formed and tapered from the end of the end to the lower end so as to serve as a bearing, and the dual slip ends 37 and 40 are introduced, and the elastic part of the circle in the pipe ( 5-50) to introduce a tension washer 29 having a radial piece, and to form a circular groove 33 in the upper end portion of the inner diameter socket 30, cushioning (31) to enable disassembly and coupling. This is accomplished by introducing new and further advancing its combined configuration.

First, a rubber O-ring 26 is inserted into the basic body 25, and then a sleeve 27 having a taper angle is inserted. Next, a tension member having a spinning piece and a strong elastic restoring force is inserted. The washer (29) is inserted, the inner diameter small cat is inserted, the outer diameter small cat is inserted next, and finally the plastic deformation is applied to the series of parts inserted into the basic body by bending at an angle of 45 degrees to the upper end of the basic body. Being able to be fixed, when the cushion ring 31 is assembled, the completion is described as follows for each part.

The cushioning ring 31 is seated on the outer diameter of the hollow inner diameter small cat 30 in which a circular groove 33 is formed at the upper end of the inner diameter small cat 30 to form a push surface that can be pressed by hand. And this cushioning ring 31 is designed to selectively detachable according to the operator's convenience.

The inner diameter small cat (30) has a step (40), the outer diameter of which is different in the outer diameter, the hook portion 33 is formed at the upper end, the tapered portion 41 is formed at the lower end, the hook portion 33 is cushioning ring 31 It is a seating circular groove of the bottom and the taper 41 is formed and interacts with the tension washer, so if the pipe is required to be reconstructed after the reconstruction of the pipe and the connector when pressing the radial piece 36 of the tension washer 29 It plays the role of smoothing when disassembling pipes and connectors.

In addition, unlike the conventional washer (Figs. 1-6), the sleeve 27 is made of a synthetic resin having a strong material. The overall shape is a thick ring shape, and the inner side has the same inclination corresponding to the taper portion 41 formed on the inner diameter small cat. The other tapered portion is formed, the outer peripheral surface is inserted and fixed to fit snugly to the inner peripheral surface of the base body 25.

The tension washer 28 has a plurality of radial pieces 36 are radially formed toward the center of the inner side, the radial piece is a part of the shape of the circle (Fig. 5-50) to match the diameter of the pipe is strong elasticity and corrosion resistance This excellent material was rewritten.

The O-ring 26 is inserted into a sealing step 42 formed inside the base body, and is fixed by the sleeve 27 and completely sealed by the outer diameter small cat 27 to be combined to secure the airtightness of the fluid flowing through the two pipes. It plays a role.

The outer diameter small cat (29) serves to restrain the left and right flow of the inner diameter small cat (30) while serving to fix and protect the components seated inside the base ().

In detail, the outer diameter small cat has two hollows with different inner diameters (40), and this hollow has a sliding bearing principle of tolerance, which has a low coefficient of friction and a smooth slip phenomenon while contacting the outer diameter (37) of the small inner cat. .

Finally, when the uppermost end of the basic body 25 is bent 38, the component assembly is completely fixed as shown in the cross-sectional view of FIG. This embodiment is very useful when applied to the case of copper pipe customs difficult to weld.

In addition, the lower side of the base body may be screwed and fixed through mutual screwing. At this time, it is preferable to process the same as the pipe insertion hole diameter of the base body.

When the component assembly is fixed by the bending 38 as described above, one end of the pipe is opposed to the insertion hole 34 and then inserted, and then firmly fixed as shown in FIG. 4 through the operation as described above. However, if the pipe 2 needs to be calibrated, such as being inserted at an oblique angle, or needs to be separated after the two pipes have been inserted and fixed again, the pipe may be easily pulled by pressing the cushioning ring 31 by hand. Decomposition was allowed.

Explain this

When the cushioning ring 31 is pressed by hand force, the force is received by the taper portion 41 of the inner diameter small cat 30, and the radial pieces 36 of the tension washer are tapered portions of the sleeve 27. The force exerted on the outer circumferential surface of the pipe by releasing it slightly to the shaft is released, so that the fixing can be released so that the coupling can be easily corrected or the pipe can be detached.

As described in the detailed description above, the present invention has all the advantages of the conventional pipe connection structure and eliminates many of the disadvantages, so that the pipe can be easily connected and the connected pipe can be easily separated even after the completion of the fastening, while eliminating the cushioning. If you use a tool or tools can be separated easily.

In addition, it is possible to work in a narrow space where work tools or tools cannot be used, so it can be easily repaired or repaired. It has a very economical effect such as shortened and reduced piping materials.
