Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

The following working principles, detailed connecting means thereof, and the following main descriptions of the working principles and processes are well known in the art, and will be referred to by those skilled in the art for the specific connection and operation sequence of the components in this application.

As can be known from figures 1 to 4, the novel connector structure for the PP-R pipe fitting comprises a sleeve 1, wherein movable pipes 2 are movably connected to two inner sides of the sleeve 1, a boss 4 is arranged at one end, located inside the sleeve 1, of each movable pipe 2, one end, away from the sleeve 1, of the inner wall of each movable pipe 2 is provided with an internal thread 3, seal sleeves 5 are fixedly connected to two inner sides of the inner wall of the sleeve 1, and the inner walls of the seal sleeves 5 are movably connected to the outer walls of the movable pipes 2.

In the specific implementation process, it is worth pointing out in particular that the boss 4 can avoid the movable pipe 2 to break away from the inside of the sleeve 1, and through the cooperation of the movable pipe 2 and the sleeve 1, it is realized that, after two PP-R pipe fittings are installed, but when not connected with each other, the movable pipe 2 can be retracted to the inside of the sleeve 1, then the novel connector structure of the PP-R pipe fitting is placed between the two outside PP-R pipe fittings, the movable pipe 2 is drawn out from the inside of the sleeve 1, and is in threaded connection with the outside PP-R pipe fitting, so that the installation and the disassembly are convenient, wherein the sealing sleeve 5 ensures the sealing performance between the movable pipe 2 and the sleeve 1, and the sleeve 1 can be designed into different bending angles or three-way joints, four-way joints and the like, which are specifically determined according to actual conditions.

Furthermore, the side wall of the boss 4 is provided with an annular groove 6 matched with the sealing sleeve 5.

In the specific implementation, it is worth noting in particular that the annular groove 6 is provided in order to improve the degree of engagement between the sealing sleeve 5 and the boss 4.

Further, a heat shrink tube 7 is arranged outside the sleeve 1, and the end of the heat shrink tube 7 extends to the outer wall of the movable tube 2.

In the specific implementation process, it is worth pointing out that the heat shrinkable tube 7 is arranged to seal the movable tube 2 and the sleeve 1 again after the movable tube 2 is connected with the external PP-R pipe, so as to further improve the sealing performance.

Furthermore, a lantern ring 8 is embedded in the outer wall of the movable tube 2.

In the specific implementation process, it is worth pointing out in particular that the collar 8 is arranged to facilitate observation of the length of the movable tube 2 inside the casing 1, that is, the pressure of the sealing sleeve 5, and facilitate judgment of whether the sealing sleeve 5 has an effective sealing effect between the boss 4 and the casing 1.

Further, the outer wall of the lantern ring 8 is provided with a scale bar 9.

In the implementation, it is worth noting in particular that the graduated strip 9 facilitates the user to observe the position of the collar 8.
