[0002] When PE pipes are used in urban water supply project construction, they need to be installed. When installing PE pipes, there should be no debris at both ends of the pipes. Therefore, both ends of the pipes need to be temporarily blocked at the end of each work to prevent debris from entering the pipes.

[0003] At present, a connecting end cap is used for sealing PE pipes. The staff connects the end cap to the pipe mouth of the PE pipe to seal the pipe mouth of the PE pipe. However, the manual installation of the end cap at the sealing position is slow. The installation of large pipe end caps requires the help of tools and equipment, which is time-consuming and labor-intensive, and the work efficiency is slow. Therefore, an M-type PE plastic toughened end cap is designed to solve this problem. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art, and to propose an M-type PE plastic toughened end cap, which is conducive to improving the installation efficiency of the end cap at the sealing part of the PE pipe. The installation can be completed manually without the aid of tools, thereby ensuring the use and maintenance of the pipe, making the use effect of the M-type PE plastic toughened end cap better.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An M-shaped PE plastic toughened end cap is designed, comprising a toughened outer end cap, wherein a plurality of arc-shaped positioning plates are equidistantly arranged in a ring at one end of the toughened outer end cap, wherein the inner sides of the plurality of arc-shaped positioning plates are rotatably connected to a limiting irregular plate, wherein the limiting irregular plate is in a cross shape, and the top end of the limiting irregular plate is fixedly connected to a limiting active hook, wherein the limiting active hook is made of steel material, and a toughened inner end cap is arranged on the inner side of the toughened outer end cap.

[0007] Preferably, the outer surface of the toughened outer end cover is provided with an external positioning plate.

[0008] Preferably, a guide thread column is rotatably mounted on the inner side of the toughened outer end cover, and a driven thread traction block is threadedly sleeved on the outer surface of the guide thread column.

[0009] Preferably, the outer surface of the driven threaded traction block is annularly equidistantly rotatably connected with a plurality of traction guide strips, and the plurality of traction guide strips are respectively rotatably connected with the inner wall of the limiting irregular plate.

[0010] Preferably, a turntable coupling is inserted and fixedly installed in the middle of the toughened outer end cover, one end of the turntable coupling is fixedly connected to a turntable rotating wheel, and the guide thread column is fixedly connected to the turntable coupling.

[0011] The utility model proposes an M-shaped PE plastic toughened end cap, which has the following beneficial effects:

[0012] After the toughened outer end cap is put into the end of the PE plastic pipe, the turntable rotating wheel is twisted from the outside, the turntable rotating wheel starts to rotate and drives the turntable coupling to rotate, thereby driving the guide thread column to rotate in the toughened outer end cap, and the rotation of the guide thread column drives the driven thread traction block to rotate and move horizontally into the pipe. When the driven thread traction block moves, it can drive multiple traction guide strips to move, and when the traction guide strips move, they start to push multiple limiting irregular plates to move in the arc positioning plate. As the multiple limiting irregular plates are spread out to the surroundings, they conflict with the inner wall of the pipe. At the same time, the limiting active hook set on the upper edge of the limiting irregular plate is plugged into the internal thread of the PE pipe, which is conducive to the high installation efficiency of the end cap at the sealing part of the PE pipe. The installation can be completed manually without the help of tools, which ensures the use and maintenance of the pipe, making the M-type PE plastic toughened end cap have a better use effect.

After the toughened outer end cap 7 is inserted into the end of the PE plastic pipe, the turntable rotating wheel 12 is twisted from the outside, and the turntable rotating wheel 12 starts to rotate and drives the turntable coupling 18 to rotate, thereby driving the guide thread column 4 to rotate in the toughened outer end cap 7. The rotation of the guide thread column 4 drives the driven thread traction block 2 to rotate and move horizontally into the pipe. When the driven thread traction block 2 moves, it can drive multiple traction guide strips 3 to move. When the traction guide strips 3 move, they start to push multiple limiting irregular plates 8 to move in the arc-shaped positioning plate 9. As the multiple limiting irregular plates 8 expand to the surroundings, they conflict with the inner wall of the pipe. At the same time, the limiting active hook 20 set on the upper edge of the limiting irregular plate 8 is plugged into the internal thread of the PE pipe, which can improve the installation efficiency of the end cap at the sealing end of the PE pipe.

When the driven thread traction block 2 moves, it can drive multiple traction guide strips 3 to move. When the traction guide strips 3 move, they start to push multiple limiting irregular plates 8 to move in the arc positioning plate 9. As the multiple limiting irregular plates 8 expand to the surroundings, they conflict with the inner wall of the pipe. At the same time, the limiting active hook 20 set on the upper edge of the limiting irregular plate 8 is plugged into the internal thread of the PE pipe. When a small toughened inner end cover 6 is set, it only needs to extend the end wall to use it.
