Socket type pipe fitting structure

Abstract

The invention discloses a socket type pipe fitting structure. The structure comprises a pipe body, a bearing port and an inserting port; a chute is formed in the end surface of the bearing port; an inner groove is formed in the inner wall of the bearing port at the tail end of the chute; a release preventing block and a limiting block are fixed on the outer wall of the inserting port in sequence; a distance from the release preventing block to the end surface of the inserting port is smaller than a distance from the limiting block to the end surface of the inserting port; in a direction of pointing from the inserting port to the bearing port, an included angle of larger than 0 degree is formed between a connecting line, of the release preventing block and the circle center, and a connecting line, of the limiting block and the circle center; the length of the inner groove in the axis direction of pipe fittings is larger than the length of the release preventing block in the axis direction of the pipe fittings; and the axial distance between the release preventing block and the limiting block is larger than the length of the chute in the axis direction of the pipe fittings, and is smaller than the length sum of the chute and the inner groove in the axis direction of the pipe fittings. The structure uses the release preventing block for achieving the purpose of preventing axial slippage of two inserted pipe fittings, and uses the limiting block for achieving the purpose of preventing relative rotation of the two inserted pipe fittings, so that the inserting connection reliability is greatly improved.

Description

technical field [0001] The invention relates to the field of socket-type pipe fittings, in particular to a socket-type pipe fitting structure. Background technique [0002] When the socket-type pipe fittings are connected into pipelines, the socket of the pipe fittings to be connected is inserted into the socket of the pipe fittings to be connected, and the seal between the pipe fittings to be connected and the axial slippage prevention are realized through the sealing ring arranged between the socket and the socket According to the feedback from the construction site, since the sealing ring is a flexible part, the binding force it can provide is limited, so the anti-slip effect of the sealing ring is not very ideal, and the pipe fittings often come off, which increases the difficulty of construction and delays Construction period. Contents of the invention [0003] In order to solve the above problems, the present invention aims to provide a socket-type pipe fitting stru...
