Furthermore, the corresponding insertion structure of the limiting block and the corresponding insertion hole / slot, along with locking bolts, securely fixes the first gasket body, the second gasket body, and the adjusting piece. This ensures both thickness adjustment and overall structural stability, preventing displacement or loosening of the adjusting piece under pressure or vibration, thus maintaining the gasket's mechanical strength and sealing performance.

The utility model relates to the field of crucible fixing, disclose a kind of for electron beam horizontal smelting furnace's crucible fixing structure, including frame, the top of the frame has two groups horizontal crucible, the inner wall of the frame is equipped with multiple groups double-end equal-length stud, the top of the frame is provided with multiple groups first support seat, the top of each group first support seat is respectively provided with a group first crucible pressing plate, multiple groups first crucible pressing plate and multiple groups first support seat are respectively sleeved in the outer wall of a group double-end equal-length stud.The utility model reserves necessary deformation space by the cooperation between groove and crucible outer buckle and crucible inner buckle, effectively relieves the internal stress caused by the difference of expansion coefficient, key components can be reused, not only play to the extreme crucible body life, also greatly reduce the spare parts procurement cost, reduce the risk of damaging crucible due to difficult disassembly, improve the safety and efficiency of maintenance operation.

The present invention relates to the technical field of bundled three-core cables, and in particular to a bundled three-core cable and a three-hole parallel mold for making the cable, comprising three cables, two adjacent cables being fixed to each other by a rib band, wherein the rib band is provided with a plurality of penetrating lattice strip holes and diamond-shaped holes. The present invention solves the problem that a tool is required to split the rib band during the installation of the existing bundled three-core cable through an innovative rib band structure design. The lattice strip holes and diamond-shaped holes are provided on the rib band. The former forms a plurality of easy-to-tear points, allowing the user to easily tear the rib band without tools, significantly improving the convenience and efficiency of installation; the latter provides a larger space, which is convenient for the user to pinch and tear it with fingers, and at the same time serves as an anchor point for fixing the cable, ensuring stability during the installation process. This design not only reduces the safety risk during the installation process, but also avoids the use of a tool.

This invention belongs to the field of superconducting wire technology and relates to an enameled superconducting round wire and its preparation method.
