Specific implementation manners
[0020] Such as Figures 1 to 7As shown in the figure, an isolated mechanical fastening fitting includes a cylindrical main body with a left-right central axis, which is fitted with a connecting column 1. On the left side of the main body connecting column 1, there is an integrally formed fastening and fitting stabilizing column 2, which projects as a regular hexagon in the left-right direction and can cooperate with a fastening tool for overall fastening during the overall fastening process. On the left end face of the fastening and fitting stabilizing column 2, there is an integrally formed cylindrical combined connecting and fitting column 3, which is the second fastening combination structure of this fastening fitting. At the center position of the left end face of the combined connecting and fitting column 3, there is a cylindrical central fitting and connecting hole 4 that penetrates through the right side of the whole, and can be inserted and combined with the structure at the fastening position. It can also be used as a hollow conveying channel, with stronger flexibility during use and can meet the fastening and fitting connections of various mechanical components. At the center position of the right end face of the main body connecting column 1, there is a cylindrical fastening combined connecting hole 5, and inside the fastening combined connecting hole 5, there is a main body fastening thread matching groove, which is the main body matching position for overall fastening connection and is fastened and combined by means of thread matching. At the connection position between the left side of the main body connecting column 1 and the fastening and fitting stabilizing column 2, there is a cylindrical isolation and safety matching groove 6 with the same central axis, so that when the whole is fastened, there is a reliable heat insulation effect between the matching structures at both ends. On the outside of the isolation and safety matching groove 6, there are evenly distributed heat insulation and safety heat dissipation grooves 7 in the circumferential direction, which can enable the heat transferred by the main body structure during use to be dissipated in a timely and efficient manner, ensuring higher safety during use. When in use, it can be selected to perform fastening and fitting at any position on the inner or outer side according to needs, with stronger flexibility during fastening. By setting the fastening and fitting stabilizing column on its main body structure, it can cooperate with a clamping tool for overall fastening and fitting, and the operation during fastening is more convenient. By setting an isolation structure on its main body structure, it can meet the safety matching requirements between components in a high-temperature environment during use, has reliable heat insulation and heat resistance during use, and has a longer service life during use.
[0021] Preferably, on the outer cylindrical surface of the combined connecting and fitting column 3, there is a spare fastening combined thread groove, which can be used for fastening and combination at this position during fastening and fitting, making the overall fastening and fitting more flexible.
[0022] Preferably, the diameter of the circumscribed circle of the fastening and fitting stabilizing column 2 is the same as the diameter of the main body connecting column 1, making the overall structure more stable and the structural strength of the fastening and fitting stabilizing column 2 higher.
[0023] Preferably, the diameter of the isolation and safety matching groove 6 is larger than the diameter of the combined connecting and fitting column 3, making the main body structure more durable and the structural safety of the heat insulation position higher.
[0024] Preferably, the heat-insulating safety heat dissipation groove 7 is of a cylindrical structure, and the diameter of the heat-insulating safety heat dissipation groove 7 is the same as the width of the isolation safety fitting groove 6, so that the space at the heat-insulating position is larger outside, and the heat dissipation fitting efficiency during use can be further improved, and the space utilization rate of the heat-insulating and heat-dissipating structure is also higher.
