Compression connection device for pipe

Abstract

Disclosed is a compression fastening device for a pipe. The compression fastening device for a pipe comprises: a tightening coupling part which has connection members connected in a manner of surrounding the circumference of a connection part of a pipe body, and which is formed so as to be capable of generating a tightening force for compression fastening the circumference of the connection part of the pipe body while operating in a state where the gap of both ends of the tightening coupling part becomes narrowed by a tightening tool; a tightening compression part which has a flow-type compression member and a fixed-type compression member formed so as to be capable of compressing the circumference of the connection part of the pipe body while being pressed in a contact state by the tightening force of the tightening coupling part; and a contact guide part which is formed so as to be capable of guiding the contact state between the tightening coupling part and the tightening compression part so that the gap of both ends of the tightening coupling part can be manipulated by the tightening tool in a set state where the gap of both ends has been narrowed.

1 . A compression connection device for pipes, comprising:

         2 . The compression connection device of  claim 1 , wherein:
 the fastening connection units have latching portions at ends of the fastening connection units on both sides, and   each of the latching portions has a groove or protrusion form into which the fastening tool is latched in such a way as to be capable of the fastening operation.   
     
     
         3 . The compression connection device of  claim 1 , wherein the fastening connection units are connected in such a way as to narrow an interval between the connectors. 
     
     
         4 . The compression connection device of  claim 1 , wherein the movable type compression unit and the fixed type compression unit are disposed on the side of the fastening connection units in the state capable of the compression operation in the direction in which the diameter of the circumference of the joint parts of the tubular bodies is narrowed while the interval between the ends of the fastening connection units on both sides are manipulated to be narrowed. 
     
     
         5 . The compression connection device of  claim 4 , wherein:
 the movable type compression unit are disposed to correspond to the ends of the fastening connection units on both sides, and   the fixed type compression units are arranged in a direction in which the movable type compression units are connected.   
     
     
         6 . The compression connection device of  claim 5 , wherein the movable type compression unit is set to be capable of the slide operation along the circumference of the joint parts of the tubular bodies on the side of the connectors of the ends of the fastening connection units on both sides. 
     
     
         7 . The compression connection device of  claim 5 , wherein the fixed type compression unit is fixed to the connector between the ends of the fastening connection units on both sides and is set to not move along the circumference of is the joint parts of the tubular bodies. 
     
     
         8 . The compression connection device of  claim 1 , wherein the contact guide units comprises a contact guide unit formed on the side of the connector of the fastening connection unit corresponding to the movable type compression unit and an elastic member formed to elastically push the movable type compression unit along the contact guide unit. 
     
     
         9 . The compression connection device of  claim 1 , wherein the contact guide surface is slantly formed from a first side of the contact surface of the connector in which the movable type compression unit is placed to a second side of the contact surface. 
     
     
         10 . The compression connection device of  claim 1 , wherein the elastic member is set to generate an elastic force in a state in which the movable type compression unit moves along the contact guide surface and is located off the end of the fastening connection unit. 
     
     
         11 . The compression connection device of  claim 1 , wherein:
 the compression connection device for pipes further comprises a holder unit corresponding to the fastening connection unit, and   the holder unit comprises a guide holder disposed at an end of the fastening connection unit on a first side and configured to have a guide hole formed in the guide holder and a latching unit disposed at an end of the fastening connection unit on a second side in a state in which the latching unit is inserted into the guide hole of the guide holder in such a way as to be latched into the guide hole.
