[0033] Embodiment 1:

[0034] Please refer to Figure 1-Figure 6 A new type of polytetrafluoroethylene lined pipe fitting includes a pipeline 1, a plug-in tube 3 is fixedly connected to one end of the pipeline 1, a plug-in groove 6 is opened at the other end of the pipeline 1 and at a position corresponding to the plug-in tube 3, the plug-in tube 3 is plug-connected to the plug-in groove 6, a first fixing ring 2 is fixedly connected to the outside of one end of the pipeline 1 at the plug-in groove 6, a second fixing ring 5 is fixedly connected to the outside of one end of the pipeline 1 at the plug-in tube 3, and a reinforcement mechanism 4 is provided at the position where the plug-in tube 3 is plugged into the plug-in groove 6 and on the outside of the second fixing ring 5 and the first fixing ring 2.

[0035] Through the above structural design, it can be known that when two pipes 1 need to be docked, the two pipes 1 are connected by plugging the plug-in tube 3 on one of the pipes 1 into the plug-in groove 6 on the other pipe 1, and then the plug-in groove 6 and the plug-in tube 3 are plugged together, and the connection between the two pipes 1 is limited and fixed by the reinforcement mechanism 4.

[0036] Specifically, the reinforcement mechanism 4 includes a first connecting shell 7 and a second connecting shell 8, and the first connecting shell 7 and the second connecting shell 8 are plugged and connected with the docking first fixing ring 2 and the second fixing ring 5, the bottom of the first connecting shell 7 is fitted with the top of the second connecting shell 8, and both ends of the top of the second connecting shell 8 are fixedly connected with a circular block 9, and limiting mechanisms 10 are arranged at the two end positions of the bottom of the first connecting shell 7, and a clamping mechanism 11 is arranged on one side of the middle part of the second connecting shell 8 and the first connecting shell 7.

[0037] Through the above structural design, it can be known that the first fixing ring 2 and the second fixing ring 5 that fit each other after the two pipes 1 are connected are plugged in through the first connecting shell 7 and the second connecting shell 8, and then the first fixing ring 2 and the second fixing ring 5 are limited by the first connecting shell 7 and the second connecting shell 8, the connection between the first connecting shell 7 and the second connecting shell 8 is limited by the limiting mechanism 10, and the fit between the first fixing ring 2 and the second fixing ring 5 is squeezed by the clamping mechanism 11.

[0038] Specifically, the limiting mechanism 10 includes a fixing block 12 . One end of the fixing block 12 close to the first connecting shell 7 is fixedly connected to the first connecting shell 7 . A sliding groove 13 is formed at the lower end of the fixing block 12 .

[0039] Among them, the limiting mechanism 10 also includes a plug-in rod 14, the number of the plug-in rod 14 is two, the two plug-in rods 14 are symmetrically arranged, the upper end of the plug-in rod 14 is fixedly connected with a slider 15, the slider 15 is slidably connected to the slide groove 13, and a first spring 16 is arranged between the two plug-in rods 14.

[0040] Through the above structural design, it can be known that when it is necessary to release the connection limit between the first connecting shell 7 and the second connecting shell 8, the two plug-in rods 14 at the same end are squeezed in a similar direction at the same time, so that the two plug-in rods 14 squeeze the first spring 16, and at the same time, the plug-in rod 14 drives the slider 15 to slide inside the slide groove 13. When the first spring 16 is squeezed, the first spring 16 stores the squeezing force. After pressing the plug-in rod 14 to separate the plug-in rod 14 from the return block 9, the first connecting shell 7 can be pulled upward, thereby driving the plug-in rod 14 to be pulled out from the inside of the return block 9. After the plug-in rod 14 is pulled out, the connection between the first connecting shell 7 and the second connecting shell 8 can be released, and at the same time, the first spring 16 releases the stored force to push the plug-in rods 14 at both ends to reset.

[0041] Embodiment 2:

[0042] The new polytetrafluoroethylene lined pipe provided in Example 1 is further optimized. Specifically, Figure 7 As shown, the clamping mechanism 11 includes a screw 17, which is located outside the first connecting shell 7 and the second connecting shell 8, one end of the screw 17 extends into the first connecting shell 7 and the second connecting shell 8, and the screw 17 is threadedly connected to the first connecting shell 7 and the second connecting shell 8.

[0044] Through the above structural design, it can be known that after the first connecting shell 7 and the second connecting shell 8 connect the first fixing ring 2 and the second fixing ring 5, by rotating the handle 18, the handle 18 drives the screw 17 to rotate, and the screw 17 is moved toward the inside of the first connecting shell 7 and the second connecting shell 8 by the rotation of the screw 17. When the screw 17 moves toward the inside of the first connecting shell 7 and the second connecting shell 8, the screw 17 drives the disc 19 to approach the second fixing ring 5, and the disc 19 approaches the second fixing ring 5 so that the clamping pad 21 fits with the second fixing ring 5. By continuously rotating the handle 18, the disc 19 continues to approach the second fixing ring 5, and the disc 19 squeezes the second spring 20, and the second spring 20 transmits the squeezing force to the clamping pad 21, and the second fixing ring 5 is squeezed by the clamping pad 21, so that the fit between the first fixing ring 2 and the second fixing ring 5 is reinforced.
