However, in actual applications, polyethylene pipes may be slightly deformed due to the influence of temperature and thermal expansion and contraction. The sealing device in the comparative patent is difficult to adapt to the deformation of the polyethylene pipe. When the polyethylene pipe expands and contracts due to thermal expansion and contraction, the extrusion block in the comparative patent may not be able to achieve a strong sealing effect on the polyethylene pipe. The extrusion block is difficult to seal polyethylene pipes of different diameters, and the sealing device in the comparative patent is difficult to detect the temperature of the surface of the polyethylene pipe, so it is difficult for the operator to adjust the sealing device in time. For this reason, we propose a polyethylene pipe with a sealing structure at the port.

By setting a sealing component and rotating a hand wheel, a threaded rod is driven to rotate, thereby driving a sealing block to move left and right, and then the polyethylene tube body can be sealed by the sealing block. Since the sealing block is a truncated cone structure rather than a cylindrical structure, it can seal polyethylene tube bodies of different calibers, so it can adapt to the deformation of the polyethylene tube. When the polyethylene tube expands and contracts due to heat and cold, the sealing block can still have a strong sealing effect on the polyethylene tube.

The above technical objectives of the utility model are achieved through the following technical solutions:

When the polyethylene pipe expands and contracts due to heat and cold, the sealing block can still have a strong sealing effect on the polyethylene pipe.

The detection component includes a connecting block, which is fixedly connected to the outside of the sealing sleeve. The outside of the connecting block is rotatably connected to a second threaded rod, which passes through the connecting block and the sealing sleeve and is threadedly connected to the connecting block and the sealing sleeve. The upper end of the second threaded rod is fixedly connected to a second hand wheel, the lower end of the second threaded rod is fixedly connected to a temperature sensor, and the outside of the sealing sleeve is fixedly connected to a display, which is electrically connected to the temperature sensor.

By setting up a detection component and turning hand wheel two, threaded rod two is driven to rotate, thereby driving the temperature sensor to move up and down, so that the temperature sensor can fit the surface of the polyethylene pipe body of different diameters, thereby detecting the temperature of the surface of the polyethylene pipe body, so that the manager can adjust the blocking block in time according to the temperature.

Furthermore, the connection assembly comprises a threaded sleeve, the threaded sleeve is fixedly connected to the outside of the polyethylene pipe body, and the threaded sleeve is threadedly connected to the inside of the sealing sleeve.

Furthermore, the limiting rod is movably connected inside the limiting hole, and the limiting rod is adapted to the limiting hole.

In summary, the utility model has the following beneficial effects:

1. By setting up a sealing component, turning the hand wheel 1 drives the threaded rod 1 to rotate, thereby driving the blocking block to move left and right, and then the polyethylene pipe body can be blocked by the blocking block. Since the blocking block is a truncated cone structure rather than a cylindrical structure, it can seal the polyethylene pipe bodies of different diameters, so it can adapt to the deformation of the polyethylene pipe. When the polyethylene pipe expands and contracts due to heat and cold, the blocking block can still have a strong sealing effect on the polyethylene pipe;

2. By setting up the detection component, turning the second hand wheel drives the second threaded rod to rotate, thereby driving the temperature sensor to move up and down, so that the temperature sensor can fit the surface of the polyethylene pipe body of different diameters, so as to detect the temperature of the surface of the polyethylene pipe body, so that the manager can adjust the blocking block in time according to the temperature.
