BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to piping connectors used to connect piping to holes in the sidewalls of manholes, and the like, and more particularly to piping connectors that can be usefully used when the connections are curved.

In general, a manhole is a cylindrical accommodating member having an inlet on a road surface and a body buried underground. As shown in FIGS. 1A and 1B, a manhole 10 has a side wall for inflow or discharge into the accommodating space. Pipes 20 are connected. As the connector for connecting the pipe 20 to the hole 11 on the side wall of the manhole 10 as described above, a hollow 31 is formed inside and a screw 30 provided with a screw portion 33 on an outer circumferential surface thereof. , Sealing member 40 for airtight was used a lot. That is, when the screw 30 is screwed into the pipe 20 by turning the screw 30, the connection is made and the head 32 is pressed against the side wall while pressing the sealing member 40, as shown in FIG. 1B. It is to create the connection structure as shown. Korean Registered Utility Model Publication No. 20-0344501 (Registration No. 2004.03.11) discloses the above-described conventional pipe fittings.

However, since the manhole 10 is usually made of a cylindrical shape as shown in the drawing, the wall surface of the connecting portion where the end of the pipe 20 is in close contact is also curved. Therefore, when the pipe 20 is connected using the connector as described above, a gap may occur between the outer wall of the manhole 10, which is a curved surface, and the end of the pipe 20, thereby causing leakage.

On the other hand, in order to solve this problem, the Republic of Korea Utility Model Publication No. 344501 has been proposed a pipe connector as shown in Figures 2a and 2b. That is, in order to increase the airtightness with the side wall of the manhole 10, the head portion 130 of the hollow 110-type screw 100 is made into a curved surface, and the contact member 200 that can be in close contact with the same curvature on the outer wall side separately. In preparation, the pipe 20 is coupled to the threaded portion 120 of the screw 100 through the socket 300 and the contact member 200. By the way, the connector is a sealing member 400 inside the manhole 10, the contact member 200 on the outside to obtain a rigid airtight structure, but because the number of parts is too large, management and manufacturing costs This considerably increases, and also the difficulty of machining is greatly increased because the head 130 of the screw 100 and the contact surface of the contact member 200 and the like must be machined to fit the curvature of the manhole 10.

Therefore, there is a need for a new type of pipe connection to solve these problems.

The present invention was created in view of the above necessity, it is possible to connect the pipe well without any gap even on the curved surface, and to provide a pipe connector with a simplified structure so that all management, manufacturing and assembly work can be easily performed. There is this.

Other objects and advantages of the invention will be described below and will be appreciated by the embodiments of the invention. In addition, the objects and advantages of the invention may be realized by the means and combinations indicated in the claims.

The pipe connector of the present invention for achieving the above object is to connect the pipe to the hole formed in the wall surface of the connection object (manhole or catchment well, etc.), the outer peripheral portion that is fitted and coupled while being elastically deformed to the hole, and It consists of a single body having an inner circumference formed with a plurality of elastic projections protruding toward the center so that the pipe is fitted and coupled.

Here, the outer circumference portion preferably includes a coupling portion fitted into the hole and a wing portion extending from the coupling portion to closely contact the inner and outer wall surfaces of the object.

In addition, the resilient protrusions are preferably arranged such that the height of the protrusion is gradually increased toward the direction in which the pipe is coupled, the side of the pipe is coupled is relatively gentle, the opposite side is inclined relatively quickly It is preferable to become a true toothed shape.

Such a monolith can be made of a rubber material that is deformable and elastic.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, the terms or words used in this specification and claims should not be construed as being limited to the ordinary or dictionary meanings, and the inventors should properly explain the concept of terms in order to best explain their own invention. Based on the principle that can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention.

Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention and do not represent all of the technical idea of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

3A and 3B illustrate a pipe 20 connection portion of the manhole 10 employing the pipe connector 500 according to the present invention.

As shown, the pipe connector 500 is made of a single body that is easily deformed and restored elastically, such as a rubber material. That is, instead of connecting the pipe 20 to the hole 11 of the manhole 10 while assembling several parts as before, using a ring-shaped connector 500 of one body as shown in the drawing, quickly and easily It was made to be able to connect.

In detail, the pipe connector 500 includes an outer circumference 510 coupled to the hole 11 and an inner circumference 520 into which the pipe 20 is fitted.

First, the outer circumferential portion 510 includes a coupling portion 511 fitted into the hole 11 and a wing portion 512 extending from the coupling portion 511. That is, when the connector 500 is pushed into the hole 11 of the manhole 10, the coupling part 511 is fitted into the hole 11 as shown in the drawing, and the wing part 512 has a manhole adjacent to the hole 11. It is in close contact with the inner and outer wall surfaces of (10). The wing 512 serves as a sealing member to close the gap of the hole 11. Of course, in the process of pushing the connector 500 in this way, the body of the rubber material is elastically crushed and is re-opened to fit in the hole (11). This elastic body provides the effect that the sealing (sealing) is good even when the connecting object is curved. That is, even when fitted on a curved surface, the body is elastically bent and closely adhered to the curved surface, so that a gap as in the past is hardly generated.

In addition, a plurality of elastic protrusions 521 protrude from the inner circumferential portion 520 toward the center of the hole. This means that when the pipe 20 is inserted into the inner circumferential portion 520, the resilient protrusions 521 tightly fit the pipe, and the protrusion of the resilient protrusions 521 is increased as it enters for easier insertion of the pipe 20. The height is arranged to increase gradually. That is, the elastic protrusion 521 is arranged in such a manner that the diameter of the inner circumferential portion 520 becomes narrower along the direction in which the pipe 20 is inserted. In this case, since the initial entry is relatively smooth, the insertion position of the pipe 20 can be easily grasped, and once the position is established, it is pushed strongly so that the resilient protrusions 521 hold the outer circumferential surface of the pipe 20 simply to be engaged. This ends.

And, the cross-sectional shape of the elastic projections 521 is made in the shape of a sawtooth in order not to fall out after the pipe 20 is coupled once. That is, the pipe 20 is coupled to the incoming side is gentle to the slope, the opposite side is composed of a steep inclined surface. In this case, when the pipe 20 to be connected comes in well on a gentle slope, the elastic projection 521 is not easily bent due to the nature of the sawtooth is a solid coupling is not easily pulled out in the opposite direction. .

When connecting the pipe 20 to the manhole 10 using the pipe connector 500 of such a configuration, the pipe connector 500 is first inserted into the hole 11 in the side wall of the manhole 10. Then, the connector 500 made of an elastic material such as rubber is elastically crushed and then fits into the hole 11 while being stretched by the elastic restoring force. Of course, the diameter of the coupling portion 511 is equal to the diameter of the hole 11, or a little larger than the diameter of the hole 11 is sufficient. In addition, the wing portion 512 is in close contact with the inner and outer walls of the manhole 10 adjacent to the hole 11 and sealed to prevent a gap. When the wall of the manhole 10 is curved, the connector 500 is also curved. Resiliently deformed to fit.

Subsequently, the pipe 20 is inserted into the inner circumferential portion 520 of the connector 500. At this time, the elastic protrusions 521 formed on the inner circumferential portion 520 are pressed by the outer circumferential surface of the pipe 20, and the pipe 20 is tightly squeezed by the elastic protrusions 521 to be in close contact with each other as illustrated in FIG. 3B. State is maintained. Further, since the plurality of elastic protrusions 521 are depressed elastically and hold the pipe 20, the seals are formed in multiple stages, and there is almost no fear of leakage.

In summary, simply insert the pipe connector 500 into the hole 11 of the manhole 10 and insert the pipe 20 therein to immediately terminate the connection.

Therefore, using such a pipe connector 500, a very efficient connection structure is implemented without gaps and quick and easy connection work.

As described above, the pipe connector according to the present invention provides the following effects.

First, since it is a unit that can be elastically deformed, the number of parts is greatly reduced compared to the existing one, which greatly simplifies management, manufacturing, and assembly work.

Second, even when the connecting object is a curved surface, since the body is elastically deformed and fits on the curved surface, the gap is hardly generated, so the risk of leakage disappears.

Third, despite the simple structure, it is possible to achieve a very stable connection by using a rigid coupling using the elastic projections.

Fourth, the piping connectors of the present invention provide advantages that are particularly suitable for structures such as manholes or sump wells. That is, as a point to be considered in a building structure such as a manhole, a sump, or the like, a connection object (manhole, a sump) or a pipe may be slightly settled. The present invention provides a connection between a connection object (manhole, a sump) and a pipe. Even though the angle is somewhat deformed, the pipe connecting body of the present invention can absorb such deformation to some extent, so that even if the connecting object (manhole, water collecting well) or the pipe is slightly submerged, the state of close contact at the connecting part is maintained by the elastic deformation. Since leakage can be prevented, it can be particularly useful in the construction industry.

As mentioned above, although this invention was demonstrated by the limited embodiment and drawing, this invention is not limited by this, The person of ordinary skill in the art to which this invention belongs, Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.
