Description

A Clip Type Connector Of PVC or Pe Double Wall Corrugated Pipe}

The present invention relates to a clip-type connecting device of a synthetic resin double wall pipe to connect the ends of the separated synthetic resin double wall pipe or corrugated pipe (hereinafter referred to as the synthetic resin double wall pipe) by the connector and the binding clip.

To explain this in more detail, a plurality of binding holes are provided at equal intervals at both edges with respect to the center of the connector formed in a cylindrical shape of a constant length at equal intervals, and the binding piece is bound to the inner circumferential surface of the ballistic ring formed in a circular shape with one side broken. Forming a binding clip formed in accordance with the ball, when the combined double wall pipe (or corrugated pipe) is inserted at each side of the connector, the binding clip is combined (binding) so that the binding piece is inserted into the binding hole at each edge. The binding piece of the binding clip to be inserted is inserted into the recess formed in the exterior of the synthetic resin double wall tube to provide a clip-type connecting device of the synthetic resin double wall tube that can be fixed to the synthetic resin double wall tube.

In general, a pipe is simply used as a method of connecting a synthetic resin tube having irregularities repeatedly formed on the outer circumferential surface such as a corrugated pipe, a corrugated pipe (synthetic resin double wall pipe), or a spiral pipe, which is a groove of both pipes to be connected. Synthetic resin double walled pipe combined with ring-shaped packing is combined by interference insertion on both sides of the pipe to maintain a certain length.In the early stage when the synthetic double walled pipe is combined, the sealing capacity is somewhat maintained, but the longer the mounting period is, As the outer surface of the packing is oxidized and hardened, the sealing capacity gradually drops, and as the pressure of the circulating fluid increases, the sealing capacity and locking ability decrease, so that the fluid not only leaks, but the coupling state is released. Will occur.

Proposed to solve this problem to some extent, the domestic utility model registration No. 290841 "connection structure of the ring-type colgate tube" and Utility Model Registration No. 307206 "corrogate pipe for flanges" is known.

It is formed in a zigzag shape while maintaining the mounting piece through which the mounting holes are perforated on the outer circumferential surface of the cylindrical connecting tube formed with the stepped portion at the center of the inner circumference in two rows, and the packing and ring-type colgate tube (PVC or PE double wall pipe) on both sides of the connecting tube. Each ring-shaped corrugated tube is inserted into each ring-shaped corrugated pipe, and a pair of semicircular split clips fixed to the outer circumferential surface of the mounting piece through the mounting holes is connected to the outer circumferential surface of the connecting piece formed on the outer circumferential surface of each semicircular split clip. The formed mounting piece is to be fastened by binding with a normal bolt (tightening rod) and a nut.

However, this is fixed (attached) to the outer circumferential surface of the connection pipe into which the packing and ring-type corrugated pipe (PVC or PE double wall pipe) are inserted from both sides, while retaining (attaching) the mounting piece in two rows. There is a hassle to fix the mounting pieces, and since the mounting pieces must be fixed to the outer peripheral surfaces of the connection pipe and the semicircular split clips, there is a problem that a lot of time is consumed, resulting in a decrease in productivity. Since the opposite mounting pieces formed on the outer circumferential surface must be fastened using ordinary bolts (tightening rods) and nuts, it is not easy to work, and the assembly and dismantling time is much used. have.

To solve this problem, I proposed a synthetic resin connector of Utility Model Registration Application No. 2004-15943.

This is made by connecting a plurality of wedge binding holes at equal intervals on both sides of the connector formed in a cylindrical shape having a constant length at equal intervals, and binding each wedge binding hole with synthetic resin double wall pipes inserted at both sides of the connector. By inserting and inserting the wedge formed with a short working piece in the center of the upper surface of the convenience, the binding piece of the wedge is inserted into the recess formed in the exterior of the synthetic resin double wall tube and both ends thereof are fixed to both ends of the wedge binding hole.

However, this has the hassle of separately forming (molding) the wedges inserted into the wedge binding holes, which are perforated at both edges of the connector, and the wedge coupling as well as having to separately insert and install the wedges formed in the wedge binding holes. When it is made to be moved to the other side in a completely inserted and moved to one side when the coupling takes a lot of work, there is a problem that somewhat falls, there is a problem that is not easy to carry the individually formed wedge.

The present invention is to provide a clip-type connecting device of a synthetic resin double wall pipe further improved to solve the above problems.

The present invention provides a plurality of binding holes at both edges at equal intervals with respect to the center of the connector formed in a cylindrical shape of a constant length at equal intervals, and the binding piece is formed on the inner circumferential surface of the ballistic ring formed in a circular shape with one surface coincided with the binding hole. When the binding clip is formed and the binding clip is inserted into the binding hole of each edge while the synthetic double wall pipe (or corrugated pipe) is inserted at both sides of the connector, the binding clip is inserted into the binding hole of the connector. It is an object of the present invention to provide a clip-type connecting device of a synthetic resin double wall pipe, in which a binding piece of a clip is inserted into a recess formed in an exterior of the synthetic resin double wall pipe to fix the synthetic resin double wall pipe.

Another object of the present invention is to form a binding clip integrally on the inner circumferential surface of the ballistic ring to the binding clip to be mounted to the binding hole of the connector can be combined more easily, the molding clip can be easily carried out, The present invention provides a clip-type connecting device for a synthetic double wall pipe that can be easily transported and stored so that it can be prevented from being lost.

Another object of the present invention is to form a detention piece on both sides of each binding piece integrally formed on the inner circumferential surface of the ballistic ring so that when the binding piece is inserted into the binding hole, it is connected to the edge of the binding hole, thereby inserting the synthetic resin inserted into the connector The present invention provides a clip-type connecting device for a synthetic double wall pipe that can strengthen the binding force by preventing the binding piece and the ball ring from escaping to the outside even when pressure is applied to the double wall pipe.
