The present invention when connecting the main pipe and branch pipe (connector pipe)

The present invention relates to a branch socket attachment device that drills an inlet on the side of the main pipe and attaches a connection pipe without using a pipe. Particularly, the branch pipe which divides the inner washer having the curved wing piece larger than the diameter of the inlet hole and spreads over the inner surface of the pipe inlet hole and fastens the inner washer by one-touch to a plurality of catching protrusions on the inner surface of the branch pipe. In the socket attachment device, it is a tubular packing with one branch pipe bottom and one packing top, and there is a curved wing piece larger than the inlet hole at the periphery of the bullet outward end in addition to the bullet shape with the curved surface at the bottom, so that it is easy to insert into the inlet hole. The castle is simple. Also, the packing cross section has Hook (

By adding O-Ring, a soft packing material, to the rigid tubular groove of the) type, the O-ring is partially exposed in the groove and presses the birds with the fastening nut when the inner washer is caught by a number of locking projections inside the branch pipe. It is branch pipe that improves watertightness by triple sealing by wrapping O-ring around the periphery of inlet end.

Utility Model Registration No. 54114, Patent Registration No. 225419, Patent Application No. 10-2004-0075290, Patent Application No. 10-2006-0068953, Patent Application No. 10-2006-0108620 And, there is Japanese Patent Registration No. 3415900 and Korea Patent Registration No. 772712, which will be described in more detail as follows.

Utility Model Registration No. 54114 (branch socket attaching device) is provided with a split washer on the inner surface of the outlet hole by pulling one or two or more split washers connected to them on the inner surface of the outlet hole (inlet hole). The present invention relates to a branch socket attachment device for tightening and tightening with a female screw of a split washer (inner washer) by a plurality of bolts on the inner surface of the branch socket.

Patent registration No. 225419 (one side fastening device using a washer with a bent) divides the circular washer larger than the fastening hole (inlet hole) to form a bent part in the cross section, and one is divided into the washer (inner washer) When it is inserted into the fastening hole, it is folded and inserted in the bent part, and the circular washer that is circular in shape is largely spread (divided inner washer) inside, and the bent part forms the central axis (the hinge). , Packing, adhesive tape, spring, casing, or cutting washer and the bent part (in thin bent part), and the like is used to fold it using such a round washer is a fastening device used for bolts, nuts, pipe sockets and the like.

Patent application No. 10-2004-0075290 (watertight method of branch pipe and branch pipe socket attachment device using the same) places one donut-type packing on the curved wing piece larger than the inlet hole, or is integrated with the curved wing piece and branch pipe When assembling the inner washer protruding tube female thread with a number of bolts on the inner side, the lower part of the branch pipe pressurizes and seals the donut-shaped packing, and the top and bottom of the saddle protruding pipe attached to the outer surface of the branch pipe are pressurized with a nut. Even though the shape is different, it is used in common.At this time, longitudinal grooves are formed up and down the periphery of the outer surface of the branch pipe, and longitudinal rails are formed on the inner surface of the saddle to move up and down, and to prevent the branch pipe from turning together when tightened with nuts. Is characteristic.

Patent application No. 10-2006-0068953 (watertight method for branch pipe socket attaching device) is integrated with the center of packing which is tubular in the upper part of donut type packing center hole of patent application No. 10-2004-0075290, and the upper part is the lower part of branch pipe Water-tightness is a structure which is watertight by tightening the inner washer curved wing piece larger than the inlet hole and the curved wing piece packing (donut-shaped packing) integral with the lower side of the branch pipe thereon.

The above technique has a problem in that only one outside of the pipe or the pipe inner surface is watertight.

Japanese Patent Registration No. 3415900 and Korean Patent Registration No. 772712 are common for watertight packing. The saddle-shaped curved wing piece is integrally formed on the outward side of the tubular packing. The bottom of the packing is enlarged by the curved blades at the end of the movable tube or branch pipe, which makes the periphery of the inlet end and the inside of the inlet hole closed. There is a problem that the hole is enlarged or the soft packing material is pulled out of the inlet hole due to the error of the pipe and the inner surface of the pipe is not watertight, there is a problem that the packing should be replaced if the thickness is different depending on the type of pipe.

The present invention is to solve the problems of the background art, the lower part of the cylindrical tube and the upper part of the tube-shaped packing of the elastic material is integral, the lower surface of the packing is a bullet type and the cross-section hook type and soft packing in the groove With the packing with the O-ring inserted, it is inserted into the inlet hole by One-Touch and the inner washer projecting tube is easily inserted into the inner surface of the pipe.

The technical task of watertight below the branch pipe and the top of the packing,

The tubular packing is made of relatively hard packing material for overall structural stability, so it is easily plugged into the inlet hole for good workability, and at the same time, the area in contact with the inner periphery of the inlet hole and the periphery of the inlet hole end and the inlet hole are soft for improved watertightness. Packing development problem formed by O-ring or caulking material, etc.,

The inner side of the protruding tube is formed in a bullet shape so that the inner washer can be easily inserted into the packing inner surface. When the inner washer is forcibly pulled up, the branch inner surface has a plurality of locking protrusions having elastic members. With the problem to take in Touch),

In the background art, the bisected inner washer was used to add a bulge to press the packing on the curved wing piece larger than the inlet hole of the inner washer by using a bent portion or a hinge and a manned line (tension line) to be triple watertight. The inner washer development task,

Another problem is that even if the part of the periphery of the end of the inlet hole is damaged due to earth pressure, etc., the part of the end of the inlet hole is damaged and the hole is enlarged due to the hole cutter error. The problem to be solved is to develop a branch socket attachment device that can be used in common even by replacing the washer.

The present invention comprises a branch pipe, a packing, a saddle, an inner washer, a nut, a projection having a plurality of elastic members in order to solve the problems of the background art described above.
