The specific embodiment is as follows:

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-5, an embodiment of the present utility model is provided: an injection port plug of a high-efficiency heat-insulation foamed plastic composite pipe.

Comprising the following steps: a plug body 01, wherein a movable piston 02 is arranged in the plug body 01;

The plug body 01, plug body 01 includes circular arc face top cap 11, the below of circular arc face top cap 11 is provided with compresses tightly screw thread 12, the below of compressing tightly screw thread 12 is provided with piston spacing 13, the inner wall of piston spacing 13 is provided with screw thread main part 14, circular arc face top cap 11 can be hugged closely on the surface of outer sheath, play sealed effect, compress tightly screw thread 12 back-off on the inner wall of outer sheath, piston spacing 13 has played spacing effect, avoid removing piston 02 and drop the injection port inside, screw thread main part 14 is by the struts back, and then make the more inseparabler back-off of compressing tightly screw thread 12 in outer sheath inner wall, play the effect of sealed foam.

Further, the arc surface top cover 11 is fixedly connected with the compression screw thread 12, and the arc surface top cover 11 can be tightly attached to the surface of the outer protection tube to play a sealing role when the injection port is plugged.

Further, the piston limiting 13 is fixedly connected with the screw tooth main body 14, the piston limiting 13 plays a limiting role, the movable piston 02 is prevented from falling into the injection port, after the screw tooth main body 14 is opened, the compression screw tooth 12 is tightly buckled on the inner wall of the outer sheath tube in a reverse mode, and the foam sealing effect is achieved.

Further, the piston limit 13 and the screw tooth main body 14 are divided into two halves, so that the piston limit 13 and the screw tooth main body 14 can be both supported, the whole structure is prevented from being extruded, and after the screw tooth main body 14 is supported, the compression screw tooth 12 is further tightly reversely buckled on the inner wall of the outer sheath tube, and the effect of sealing foam is achieved.
