DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Such as Figures 1 to 7As shown in the figure, a heat-resistant fastening component includes a cylindrical main body mating connection seat 1 made of metal material with a central axis in the up and down direction. At the center position of the upper end of the main body mating connection seat 1, there is an integrally formed cylindrical second combined fastening column 2, and they form the overall structure of this component. At the center position of the lower end of the main body mating connection seat 1, there is a cylindrical first avoidance mating groove 3. At the upper end of the first avoidance mating groove 3, there is a central combined installation hole that completely penetrates the upper end face of the second combined fastening column 2. At the center position of the upper end of the second combined fastening column 2, there is a cylindrical second heat insulation avoidance groove 4, which can achieve the heat insulation effect at the internal central position. Inside the second heat insulation avoidance groove 4, there are evenly distributed reinforcement support ribs 5 in a circular pattern. The inner sides of the reinforcement support ribs 5 are located in the internal area of the central combined installation hole. Inside the central combined installation hole, there is a combined connection thread groove, through which it can be directly fixed to a fastening screw. While ensuring the connection strength of the fastening position, the connection position has a reliable heat insulation effect, and the safety and durability during use can be guaranteed. The combined connection thread groove passes through the inner sides of the reinforcement support ribs 5. On the upper end of the main body mating connection seat 1, there are evenly distributed cylindrical installation combined columns 7. On the left and right sides of the upper end of the main body mating connection seat 1, there is a symmetrical cylindrical positioning and stabilizing mating column 6 respectively. At the center position of the upper end of the positioning and stabilizing mating column 6, there is a cylindrical first positioning and stabilizing hole 8. At the lower end of the main body mating connection seat 1, at a position below the first positioning and stabilizing hole 8, there is a cylindrical second positioning and stabilizing hole 9, which can be matched with a fixing and positioning shaft in the up and down direction of the installation position as needed, so as to improve the overall installation stability. The second positioning and stabilizing hole 9 communicates with the first positioning and stabilizing hole 8, and the central axes of the second positioning and stabilizing hole 9 and the first positioning and stabilizing hole 8 do not coincide, which can make this position have a certain heat resistance and ensure better safety during use. When its main structure is installed, through the avoidance groove arranged in the up and down direction at the center position, it can play a heat insulation effect. The main structure can meet the direct mating installation of surrounding components, can replace the use of traditional screw-type components and mounting brackets, is more convenient to operate during assembly, has better structural stability, can effectively improve the mating efficiency during installation during use, and can ensure that the components installed at the upper end structure have reliable heat resistance during use, and the overall safety during use is higher.

[0020] Preferably, the upper ends of the reinforcement support ribs 5 do not exceed the upper end face of the second combined fastening column 2, so that the space occupied by the upper end position is smaller, and the situation of easy interference at the upper end position during assembly can be avoided.

[0021] Preferably, the depth of the second heat insulation avoidance groove 4 is greater than the height of the second combined fastening column 2, so as to further improve the internal heat insulation effect and make the overall heat resistance better during use.

[0022] Preferably, an integral reinforcement structure is provided on the upper end surface of the main body cooperating with the connecting seat 1, so that the strength of the main body structure is better, the safety during use is higher, and it can assist the main body structure in heat dissipation cooperation and can be used as a heat dissipation rib.

[0023] Preferably, the upper end of the installation combination column 7 is provided with an installation cooperation threaded hole, which can cooperate with electrical components to be directly fastened by screws during connection, making the operation during cooperation more convenient.

[0024] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements or substitutions can be made, and these improvements or substitutions should also be regarded as the protection scope of the present invention.
