DETAILED DESCRIPTION

[0014] In order to more clearly understand the above purpose, features and advantages of the utility model, the utility model is further described in detail below in combination with the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0015] As Figs. 1-3 The utility model discloses a simple pipe joint, including adapter 1, the adapter 1 both ends are provided with connector 2 respectively, the connector 2 one end is sealedly connected with pipeline 8, and the other end is connected with adapter 1, the connector 2 includes sealing inner plug 21, sealing sleeve 22 and fastening ring 23, the fastening ring 23 is locked with the threaded cooperation connector 2, the sealing inner plug 21 is equipped with the inner thread cooperation adapter 1 setting.

[0016] As the further setting of the above scheme, the end of the connector 2 towards the adapter 1 extends inwards and is provided with a locking ring 24, the inner side of the locking ring 24 is provided with a circumferential limiting groove 25, and the end of the sealing inner plug 21 is provided with a limiting card 27 matched with the circumferential limiting groove 25.

[0017] As a further feature of the above scheme, the end of the connector 2 is provided with a slit 28, and the inner side of the part with the slit 28 is provided with a back groove 29. The fastening ring 23 is used to thread the connector 2 to lock it to the pipe fitting 8.

[0018] As a further feature of the above scheme, the stepped end face of the adapter 1 facing the connector 2 is also provided with a sealing groove 11 and a sealing ring 12.

[0019] As a further feature of the above scheme, the end of the sealing inner plug 21 that extends into the pipe fitting 8 is recessed inward and has a notch groove. The outer diameter of the threaded portion of the adapter 1 and the sealing inner plug 21 is larger than the inner diameter of the recessed portion.

[0020] like Fig. 2 The simplified pipe fitting shown in this embodiment includes an adapter 1. The adapter 1 has a threaded connector 2 and a sealing structure at both ends. One end of the connector 2, with a reduced-length fitting, is fitted onto the outside of a pipe fitting 8 and sealed to the pipe fitting 8 via a fastening ring 23. The other end of the connector 2 is connected to the adapter 1. The connector 2 includes a sealing inner plug 21, a sealing sleeve 22, and a fastening ring 23. The fastening ring 23 is threaded into the connector 2 for locking. The sealing inner plug 21 has an internal thread that engages with the adapter 1. The end of the connector 2 facing the adapter 1 has an inwardly folded edge with a locking ring 24. The inner side of the locking ring 24 has a circumferential limiting groove 25. The end of the sealing inner plug 21 has a limiting clip 27 that matches the circumferential limiting groove 25. The end of the connector 2 has a slit 28, and the inner side of the slit 28 has a backstop groove 29. The fastening ring 23 is used for threaded connection. The connector 2 is locked to the pipe fitting 8. During use, the sealing inner plug 21 is placed inside the pipe fitting 8, and the connector 2 is sleeved on the outside of the pipe fitting 8. It is locked by the threaded engagement of the fastening ring 23. The end part of the connector 2 with the slit 28 is tightened, so that the inner anti-reverse groove 29 is locked with the outer surface of the pipe fitting 8, keeping the connector 2 and the pipe fitting 8 connected and installed. At this time, the sealing inner plug 21 is circumferentially fixed and restricted based on the limiting card 27 set at the end and the circumferential limiting groove 25 set on the inner side of the adapter 2. Based on the setting of the sealing sleeve 22, the pipe fitting 8 and the sealing inner plug 21 are connected to form a water seal structure. The external thread structure set at the end of the adapter 1 extends into the internal thread structure of the threaded connection sealing inner plug 21. After rotation and locking, the sealing ring 12 on the adapter 1 and the connector 2 form a seal, so that the pipe can be successfully sealed and connected.

[0021] The pipe joint of the embodiment has the characteristics that, based on the arrangement of the sealing sleeve 22, the pipe joint 8 does not need to be flat at the end when being connected, and the sealing inner plug 21 is expanded when being screwed into the adapter 1, the outer wall of the expanded sealing inner plug 21 abuts against the sealing sleeve 22, and the sealing inner plug 21 is sealed on the inner wall of the pipe joint 8, and the end of the pipe joint 8 abuts against the end face of the sealing sleeve 22 and the end face of the sealing inner plug 21, thereby forming a water sealing effect.

[0022] The sealing inner plug 21 is arranged as described above, the adapter 1 of the embodiment is only sealed and connected with the sealing inner plug 21, and therefore, when the diameters of the two pipes are different, the sizes of the adapter 2, the fixing ring 23 and the sealing sleeve 22 can be changed, thereby adapting to the connection of the pipe joints 8 with different diameters.
