Fitting apparatus for connecting pipes

A fitting apparatus for connecting pipes comprising:

• a fitting unit which includes a first body into which a first pipe is inserted and a second body which is connected to the first body to form a pipe insertion space therein together with the first body and into which a second pipe is inserted, wherein in the first body and the second body, a first recessed groove and a second recessed groove spaced apart inward from the first recessed groove are formed along an inner circumferential surface thereof, respectively,
• wherein the first body and the second body comprise:
• a first member mounting part having the first recessed groove formed on the inner circumferential surface thereof;
• a second member mounting part having the second recessed groove formed on the inner circumferential surface thereof;
• a groove separation part formed between the first member mounting part and the second member mounting part;
• and
• an inner extension part which extends inward from the second member mounting part to connect the first body and the second body to each other;
• a compression member which is provided in the first recessed groove to compress and fix the first pipe or the second pipe;
• a sealing member which is provided in the second recessed groove to maintain airtightness between the fitting unit and the first pipe or between the fitting unit and the second pipe;
• and,
• a pressing unit which is mounted to cover an outer circumferential surface of the first body or the second body to press the outer circumferential surface of the first body or the second body,
• wherein the pressing unit comprises:
• a pressing body which has a fitting unit insertion space into which the first body or the second body is inserted and covers and presses the outer circumferential surface of the first body or the second body;
• and
• a first seating groove on which the first member mounting part is seated, a second seating groove on which the second member mounting part is seated are formed along an inner circumferential surface thereof, and a predetermined space corresponding the groove separation part being formed between the first seating groove and the second seating groove, the predetermined space on which the groove separation part is seated,
• wherein the pressing body is in direct contact with the inner extension part, the second member mounting part, the groove separation part, and the first member mounting part, respectively.
