Referring to fig. 1, a high-strength internal thread core print shown in the figure comprises a threaded pipe 1, a core body 2, guide blocks 3 and round holes 4, wherein the threaded pipe 1 is sleeved at two ends of the core body 2, the guide blocks 3 are fixedly connected to two sides of the core body 2 at equal intervals, and the round holes 4 are symmetrically formed in the outer side of the core body 2 at equal intervals.

When core 2 is rotatory, guide block 3 can carry out rotary motion along 1 internal thread of screwed pipe, the screwed pipe 1 that two screw thread screw direction of both ends are opposite is along with core 2 approaches or separates fast to carry out and be close to the laminating each other and fix or the separation is dismantled, core 2 is carrying out the thread engagement with screwed pipe 1 and is connected the time, no matter 1 internal thread screw direction of screwed pipe clockwise or anticlockwise can both be rather than the meshing, the material has been saved to round hole 4 of seting up, still strengthened the heat dissipation.

Referring to fig. 1 and 4, the spiral directions of the threads in the threaded pipes 1 at the two ends of the core body 2 are opposite, and the threaded pipes 1 in the spiral directions only approach or separate from each other when the core body 2 rotates, which is not only more convenient when the core body is fixedly connected, but also the two threaded pipes 1 approaching each other are more firm.

Referring to fig. 4, the distance between the centers of the adjacent guide blocks 3 outside the core body 2 is the same as the distance between the centers of the adjacent spiral tooth grooves in the threaded pipe 1, when the thread in the threaded pipe 1 rotates, each turn of the thread rotates along the two guide blocks 3 on both sides, and the guide blocks 3 can slide along the spiral tooth grooves.

Referring to fig. 2 and 4, the guide block 3 is diamond-shaped, and the inclination of the four sides of the guide block 3 is the same as the inclination of the internal thread of the threaded pipe 1, and when the guide block 3 is connected with the threaded pipe 1, both clockwise threads and counterclockwise threads can be attached to the opposite inclined surfaces on the two sides.

Referring to fig. 3 and 4, the guide blocks 3 on both sides of the core body 2 are uniformly staggered, and the distance between the guide block 3 on one side and the adjacent two guide blocks 3 on the other side is the same, and the threads in the threaded pipe 1 can drive the threaded pipe 1 to horizontally move outside the core body 2 along the guide blocks 3 alternately arranged on both sides.

Referring to fig. 4, the distance between adjacent guide blocks 3 outside the core 2 is the same as the width of the internal thread of the threaded pipe 1, and when the core 2 is connected with the threaded pipe 1, the outer guide blocks 3 are more attached to the internal thread of the threaded pipe 1, so that the fixation is firmer.

Referring to fig. 1 and 4, the core 2 is cylindrical, so that the material is saved, the heat dissipation is facilitated, and the core 2 can conduct some liquid after being connected with the threaded pipe 1.
