CONNECTION SOCKET OF THE PIPE

摘要

The purpose of the present invention is to secure mutual airtightness with a pipe by inserting a pipe shaped packing hose into a joint pipe. A connection socket for pipes comprises: a hollow type joint pipe (1) which can insert a pipe in order to maximize safety by maintaining and fixating a packing hose firmly at the position thereof; a packing hose (2) which can maintain airtightness between the joint pipe (1) and the pipe by closely adhering to the inner circumference of the joint pipe (1); and a wire band (3) which strengthens the airtightness between the joint pipe (1) and the pipe through compression of the packing hose (2) by regulating the length of a belt in a state of surrounding the packing hose (2), and can regulate the length of the belt from the outside of the joint pipe (1). The packing hose (2) is formed of a hollow type pipe body capable of adhering to the inner circumference of the joint pipe (1) and being compressed to the outer circumference of the pipe (p-1, p-2). The both side ends of the packing hose (2) have elasticity in order to cover both fore-end units of the joint pipe (1) and to elastically compress the both fore-end units. The provided connection socket for pipes are formed by fastening both ends of the packing hose (2) so that the outer circumferential surface of both ends of the packing hose (2) can closely adhere to the outer surface of both fore-end units of the joint pipe (1).
