Embedded PVC (polyvinyl chloride) direct pipe fitting
The invention discloses a pre-embedded PVC direct pipe fitting, and relates to the field of PVC pipe fittings, the pre-embedded PVC direct pipe fitting comprises a pipe barrel and a pipe cap covering a top opening of the pipe barrel, and the top end of the inner wall of the pipe barrel is provided with a plurality of groups of insertion pieces rotationally connected through hinge shafts; the inserting piece comprises a lower bending part, an upper bending part and a hinged ring, the hinged ring is arranged at the joint of the lower bending part and the upper bending part, the lower bending part and the upper bending part form a bent angle, and the length of the lower bending part is larger than that of the upper bending part. A plurality of groups of inserting pieces are rotatably arranged on the inner wall of the pipe barrel, each inserting piece is composed of an upper bending part and a lower bending part, when an external pipeline is inserted, the bottom end of the external pipeline can abut against the lower bending part to move downwards, and meanwhile, the lower bending part can drive the upper bending part to rotate until the top of the upper bending part abuts against the external pipeline; and the insertion stop piece cannot continue to rotate, the insertion of the external pipeline is stopped, and the external pipelines of various sizes can be inserted through the structure.
本发明公开了一种预埋式PVC直接管件，涉及PVC管件领域，包括管筒与盖合管筒顶部开口的管帽，所述管筒内壁顶端设置有多组通过铰轴转动连接的插止件；所述插止件包括下折弯部分、上折弯部分与铰接环，所述下折弯部分与上折弯部分的连接处设置有铰接环，且下折弯部分与上折弯部分形成折角，所述下折弯部分的长度大于上折弯部分的长度。本发明通过在管筒内壁转动设置多组插止件，插止件由上折弯部分与下折弯部分构成，在插入外接管道时，外接管道底端会抵住下折弯部分向下运动，同时下折弯部分会带动上折弯部分转动，直至上折弯部分的顶部抵住外接管道时，插止件便不能继续转动，外接管道也就停止插入，此种结构可插入多种尺寸的外接管道。
