1. A pipe fitting connector, comprising:
a first connection member (1), wherein the first connection member (1) comprises a first columnar pipe fitting (11);
a sealing member (2), wherein the sealing member (2) is arranged on an outer wall of the first connection member (1);
a second connection member (3), wherein the second connection member (3) comprises a second columnar pipe fitting (31); the first columnar pipe fitting (11) extends into the second columnar pipe fitting (31); the sealing member (2) is located between an outer wall of the first columnar pipe fitting (11) and an inner wall of the second columnar pipe fitting (31) to seal the first connection member (1) to the second connection member (3);
and a locking piece (4), wherein the locking piece (4) is connected to the first connection member (1); the locking piece (4) comprises an annular member (43), two or more elastic arms (41) and hooks (42); wherein the annular member (43) is sleeved on the first connection member (1); the annular member (43), the elastic arms (41) and the hooks (42) are integrally formed; wherein the elastic arms (41) extend from the annular member (43), and the elastic arms (41) and the annular member (43) form a trapezoid structure; the hook (42) is formed on an outside surface of one end of the elastic arms (41) away form the annular member (43); when the first connection member (1) and the second connection member (3) are sealed, the elastic arms (41) extend into locking through holes (32) formed in the second connection member (3) to generate a pre-tightening force on inner walls of the locking through holes (32); and the hooks (42) are simultaneously hooked to end faces of the locking through holes (32) to lock the first connection member (1) to the second connection member (3).
