[0004] However, in actual use, due to the water hammer phenomenon, thermal expansion and contraction and other conditions existing in the pipe, the connection strength between the insert and the pipe joint is insufficient, especially after the installation of the faucet, valve or plug is completed, the insert is often unstable in connection with the pipe joint due to the influence of torsional force, resulting in sealing failure between the insert and the pipe joint. SUMMARY

[0005] The utility model discloses a high torsional copper insert to solve the technical problems of ensuring the stability and sealing performance of the connection between the insert and the pipe joint.

[0006] The utility model discloses a high torsional copper insert, including the body of cylinder, the body one end has and presents the cover shape's flanging portion to the outward convexity along the circumference, its characterized in that, the outer edge of flanging portion is equipped with a plurality of upper anti -rotation groove, and a plurality of upper anti -rotation groove is along the circumferential interval setting of flanging portion, the other end face of body is along the circumference and is equipped with a plurality of interval setting's lower anti -rotation groove.

[0007] The application includes a body in a cylindrical shape and internally provided with internal threads, and a flange part in a cover shape is arranged at one end of the body, so that the body has higher structural strength. When manufacturing a pipe joint, the worker needs to place the body in the mold in advance and integrally form a plastic pipe joint on the outside. Compared with the prior art, the application firstly opens several upper anti-rotation grooves on the outer edge of the flange part in the circumferential direction, so that the liquid plastic can flow into each upper anti-rotation groove during injection molding. After cooling and solidification, it is fully connected with the inner wall of each upper anti-rotation groove. Secondly, several lower anti-rotation grooves are opened on the other end face of the body. Similarly, the liquid plastic can flow into each lower anti-rotation groove during injection molding. After cooling and solidification, it is fully connected with the inner wall of each upper anti-rotation groove. By arranging the upper anti-rotation grooves and the lower anti-rotation grooves, the connection strength of the body and the pipe joint is higher, especially in the circumferential direction. When the worker assembles the pipe joint in the pipeline system, the plastic blocks solidified in each upper anti-rotation groove and each lower anti-rotation groove are used to bear the torsional force generated during screwing. The connection reliability of the body in the pipe joint is fully guaranteed, the connection between the circumferential outer wall of the body and the pipe joint is prevented from being unstable due to the application of torsional force, thereby avoiding the generation of gaps to cause the sealing failure between the body and the pipe joint, and further preventing the water leakage condition, effectively guaranteeing the connection stability of the body in the pipe joint and the sealing between the two.

[0008] In the high-torsion copper insert described above, each of the upper anti-rotation grooves is strip-shaped and is arranged in a clockwise direction along the circumferential direction of the flange part. The standard structure commonly used in the prior art is needed. The internal threads arranged inside the body are generally arranged in a counterclockwise direction. Therefore, the application arranges each upper anti-rotation groove in a counterclockwise direction along the circumferential direction of the flange part, so that the torsional force applied to the body and the reaction force of the plastic blocks formed in the upper anti-rotation grooves are exactly opposite during connection and assembly, thereby maximizing the connection stability of the body and further improving the sealing effect between the body and the pipe joint.

[0009] In the high-torsion copper insert described above, each of the lower anti-rotation grooves penetrates the lower end inner and outer side walls of the body and is wedge-shaped. By this arrangement, the size of the plastic blocks solidified in the lower anti-rotation grooves is larger, which cooperates with the plastic blocks solidified in the upper anti-rotation grooves to ensure the connection stability of the body. Secondly, the lower anti-rotation grooves are arranged in a wedge shape, so that the holding force of the plastic blocks in each lower anti-rotation groove on the body in the axial direction is also improved, ensuring the connection stability of the body.

[0010] In the high-torsion copper insert described above, several of the lower anti-rotation grooves are arranged in groups of two, and the two lower anti-rotation grooves of the same group are arranged opposite each other. By this arrangement, during processing, the two lower anti-rotation grooves belonging to the same group can be polished and processed at one time by a milling tool, effectively improving the manufacturing efficiency.

[0011] In the high-torsion-resistance copper insert, a plurality of anti-rotation ribs are fixed between the inner wall of the top of the flange portion and the inner side wall, the plurality of anti-rotation ribs are arranged at intervals in the circumferential direction of the body, and the plurality of anti-rotation ribs and the plurality of upper anti-rotation grooves are alternately arranged. The arrangement of the plurality of anti-rotation ribs can effectively improve the connection strength between the body and the flange portion. In addition, during the injection molding process, the plastic can fully cover and consolidate each anti-rotation rib. After cooling and setting, if the body is twisted during installation, the anti-rotation ribs can cooperate with the plastic blocks in the upper anti-rotation grooves and the lower anti-rotation grooves to withstand the torsional force, effectively improving the connection stability of the body.

[0012] In the high-torsion-resistance copper insert, each of the anti-rotation ribs is in the shape of a long strip, and each anti-rotation rib and the inner wall of the top of the flange portion and the inner side wall of the flange portion form a through hole in the shape of a triangle. Through this arrangement, during the injection molding process, liquid plastic can flow into each through hole, thereby improving the coverage of the plastic on each anti-rotation rib after sufficient cooling. At the same time, the plastic consolidated in the through hole can also cooperate with the plastic blocks in the lower anti-rotation grooves to withstand the pulling force applied in the axial direction of the body.

[0013] In the high-torsion-resistance copper insert, the outer side wall of the body has upper and lower axial anti-extraction grooves arranged in the circumferential direction, the upper and lower axial anti-extraction grooves are arranged at intervals in the axial direction of the body, and the upper and lower axial anti-extraction grooves are wedge-shaped when the body is cut in the axial direction. The arrangement of the upper and lower axial anti-extraction grooves allows liquid plastic to flow into and consolidate during the injection molding process, thereby further improving the connection stability of the body and the pipe joint. Moreover, the upper and lower axial anti-extraction grooves are wedge-shaped when the body is cut in the axial direction, thereby ensuring the connection stability between the plastic consolidated in the upper and lower axial anti-extraction grooves and the pipe joint.

[0014] In the high-torsion-resistance copper insert, the outer side wall of the body has an installation groove arranged in the axial direction, and the installation groove is located below the lower axial anti-extraction groove. If the body has certain defects in air tightness, a sealing ring can be installed in the installation groove to avoid such defects.

[0015] Compared with the prior art, the high-torsion-resistance copper insert has the following advantages:

[0016] 1. The arrangement of the plurality of upper anti-rotation grooves and the plurality of lower anti-rotation grooves allows liquid plastic to consolidate inside during the injection molding process, ensuring that the injection molding structure of the body and the pipe joint has higher strength and effectively preventing the existence of torsional force from causing unstable connection between the body and the pipe joint, thereby avoiding sealing failure between the two.

[0017] 2, the setting of several anti-rotation ribs of copper improves the connection strength between the flanging part and the body, and the connection strength of the body is improved by the cooperation of the anti-rotation ribs, several upper anti-rotation grooves and several lower anti-rotation grooves.

[0018] 3, through the setting of the upper axial anti-falling groove and the lower axial anti-falling groove, the through hole formed between the anti-rotation rib and the flanging part, so that the structure strength of the body in the axial direction is improved after injection molding.
