Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

2 is a rear perspective view showing an elliptical connector conforming to a circular manhole according to the present invention, and Fig. 3 is a perspective view showing a circular shape according to the present invention. Fig. Fig. 4 is a longitudinal sectional view showing an elliptical connector conforming to the circular manhole according to Fig. 2, and Fig. 5 is a longitudinal sectional view showing an elliptical connector conforming to the manhole, Fig. And FIG. 6 is a perspective view showing another example of the elliptical connector according to the circular manhole according to the present invention.

1 to 5, an elliptical connector according to the present invention is connected to an outer wall of a circular manhole 30 and connected to a pipe 40 for transferring collected rainwater or sewage to a treatment plant And includes a connector body 10 and a flange 20 extending outwardly at one end of the connector body 10. [

The present invention is produced by a vacuum molding method in which a plate or pile of a thermoplastic resin is heated and deteriorated to suck air between a mold and a mold to press the mold against the mold, It is preferable that it is made of a synthetic resin material such as rubber. Particularly, the present invention is fixed by a flange 20 protruding in a direction orthogonal to one end of the connector body 10 and embedded in a wall surface of the circular manhole 30.

The connector body 10 includes a circular connection portion 11 through which the pipe 40 is inserted and a tapered portion 12 formed in a funnel shape between the end portion of the connection portion 11 and the flange 20 .

In particular, since the tapered portion 12 secures a wide space, the angle of the pipe 40 connected through the connection portion 11 can be easily adjusted.

On the other hand, a triangular groove 111 is formed in the inner circumferential surface of the connection part 11 to guide the tube 40 to be folded inwardly so that the tube 40 can be easily inserted, .

That is, when the tube 40 is connected, the tube 40 can be inserted through the connection portion 11 or the tube 40 can be inserted while the connection portion 11 is folded inward. At this time, The connecting portion 11 can be easily folded through the connecting portion 11. In addition, while the pipe 40 is inserted into the connection part 11, the folded connection part 11 is unfolded and pressure is applied to the pipe 40 to prevent the pipe 40 from being detached.

A fixing band 50 may be fastened to the outer circumferential surface of the connection portion 11 so that the connection portion 11 is pressed and fixed to the pipe 40 to be connected thereto. Therefore, by tightening the outer circumferential surface of the connection portion 11 with the fixing band 50, the gap between the connection portion 11 and the pipe 40 can be completely blocked and structurally and stably connected to each other.

In addition, a plurality of separation preventing protrusions 112 may be spaced apart from the outer circumferential surface of the connection portion 11 to prevent the fixing band 50 from being separated.

Preferably, the tapered portion 12 is formed such that its diameter increases toward the outer side of the end portion of the connection portion 11 and its extended end portion 121 curves, and the cross-sectional shape of the tapered portion 12 is elliptical.

The flange 20 may be curved in a direction orthogonal to the tapered portion 12 at the extended end 121 of the tapered portion 12 and may have an elliptical cross-sectional shape.

In the case where an elliptic connector is connected to a wall surface of the circular manhole 30, a display portion 22 represented by an arrow or the like may be formed on one side of the flange 20 so that an operator can easily grasp the arrangement direction of the elliptic connector. And can be formed at an obtuse angle.

As described above, the elliptical connector conforming to the circular manhole according to the present invention is formed so that the extended end of the tapered portion 12 and the flange 20 are curved in correspondence with the circular manhole 30 whose outer shape is curved, So that watertightness performance can be greatly improved as concrete pouring is uniformly performed around the connector.

As shown in FIG. 6, a fill groove 21 may be formed on both sides of the flange 20 to fill the concrete and prevent the flange 20 from flowing and deforming. .

The reason why the width of the fill groove 21 is increased toward the inner side is that the concrete is filled in the fill groove 21 formed in the flange 20 of the connector and hardened during the filling of the concrete, To prevent deformation such as flow and contraction of the flange 20 which is coupled in a curved shape so as to increase water tightness and binding force.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art without departing from the scope of the invention.
