Description

Locking Bar Type Synthetic Resin Double Wall Pipe End Connection {A Connector Of PVC Or PE Double Wall Corrugated Pipe}

The present invention relates to an improved locking bar type synthetic resin double wall pipe end connection which connects separated PVC or PE double wall corrugated pipe or corrugated pipe (hereinafter referred to as 'synthetic resin double wall pipe') to each other by a connector. .

In more detail, a plurality of pairs of locking balls formed in a straight or bent (L-shape) or T-shape end of the connection pipe through the pair of locking holes facing each other, the locking bar and the bar holder in the opposite locking hole Insert the locking bar into the locking hole while inserting the synthetic resin double wall pipe (or corrugated pipe) with packing on the distal end of the connecting pipe, and insert it through the main part of the synthetic double wall pipe (or corrugated pipe). By fastening the bar holder to the tip of the locking bar exposed by the locking hole on one side, the synthetic resin double wall pipe (or corrugated pipe) is fastened by the locking bar inserted and locked into the locking hole, and the synthetic resin double wall pipe (or corrugated pipe) by the connection pipe. It is to provide a locking bar-type synthetic resin double-walled pipe connector that can be connected to.

In general, a pipe is simply used to connect a synthetic resin tube having irregularities repeatedly formed on the outer circumference such as a corrugated pipe (synthetic resin double wall pipe) or a spiral tube. Synthetic resin double walled pipe combined with shape-shaped packing is combined by interference insertion on both sides of the pipe to maintain a certain length.In the initial stage when the synthetic resin double walled pipe is combined, the sealing capacity is maintained somewhat, but the longer the mounting period, As the outer surface is oxidized and hardened, there is a problem that the sealing capacity is gradually decreased, and as the pressure of the circulating fluid increases, the sealing capacity and locking ability decrease, so that not only the fluid leaks but also the problem of releasing the bonding state occurs. Done.

As a proposal to solve this problem to some extent, Korean Utility Model Registration No. 290841, "Connecting structure of a ring-type colgate tube," is known.

It is formed in a zigzag shape while maintaining the mounting piece through which the mounting hole is perforated on the outer circumferential surface of the cylindrical connection tube having a stepped portion formed 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 connection 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.

The present invention is to provide an improved locking bar type synthetic resin double wall pipe (PVC Or PE Double Wall Corrugated Pipe) connector to solve the above problems.

The present invention allows a pair of locking balls, which are formed in a straight line or bent (L-shaped) or T-shaped, to pass through a plurality of pairs of locking balls facing each other and fasten the locking bar and the bar holder to the opposite locking balls. Insert the locking bar into the locking hole while inserting the synthetic resin double wall pipe (or corrugated pipe) with packing on the distal end of the connection pipe, and insert it through the main part of the synthetic double wall pipe (or corrugated pipe). By fastening the bar holder to the tip of the exposed locking bar, the synthetic resin double wall pipe (or corrugated pipe) is detained by the locking bar inserted and locked into the locking hole, and the synthetic double wall pipe (or corrugated pipe) is connected by the connection pipe. The aim is to provide a locking bar type synthetic double wall pipe end fitting.

Another object of the present invention, when manufacturing a connection pipe formed in a straight or bent (L-shape) or T-shape, through a plurality of pairs of locking holes in each end of the pair through the opposite hole, inserted into the locking hole By providing a locking bar and a bar holder that can be fastened, the present invention provides a locking bar type synthetic resin double wall pipe connector that can be easily manufactured at low cost by simplifying the structure and parts thereof.

Still another object of the present invention is to connect a locking bar and a bar holder to a locking hole through a connection pipe in a state in which a synthetic resin double wall pipe (or corrugated pipe) with a packing is installed at the distal end of the connection pipe. ), It is to provide a locking bar type synthetic resin double wall pipe connector that can be easily assembled and disassembled in a short time.

Another object of the present invention is to combine the sealing capping with the usual packing to the front end of the synthetic resin double wall pipe (or corrugated pipe), and to fasten the synthetic resin double wall pipe by a locking bar inserted into the locking hole, locking (Locking) The present invention provides a locking bar type resin double wall pipe end fitting that can significantly strengthen the condition.

The above and other purposes of the present invention,
