[0020] like Figures 1 to 7The figure shows a fiberglass reinforced plastic centrifugal fan assembly riveted column. It includes a main body isolation support column 1 with a regular hexagonal cross-section, which ensures a certain separation between the upper and lower structures during use. The lower end of the main body isolation support column 1 is a cylindrical main body mating connection column 2. The upper end of the main body isolation support column 1 is an integrally formed riveted mating connection seat 3, which is used to rivet the mating hole of the riveted plate. The center of the upper end of the riveted mating connection seat 3 is the main body mating connection hole 4, which can be used with a riveting machine and can also be used as a mating hole later. The lower end of the main body mating connection column 2 is provided with a conical fastening assembly connection hole 5 that communicates with the main body mating connection hole 4 and serves as the main body connection structure during fastening. The upper end of the fastening assembly connection hole 5 is provided with a welding stabilization groove 6 at the connection point with the main body mating connection hole 4. This can serve as an internal stabilization structure during welding or as a safety feature for a deformation groove to be added later. This prevents excessive tearing of the main structure from occurring during deformation, ensuring structural safety during deformation. The inner side of the fastening combination connection hole 5 is provided with a fastening deformation matching groove 7 which is circumferentially distributed and completely penetrates the outer side of the main body matching connection column 2. When fastening is performed, the outer side structure can be deformed downward under the action of this structure, so that the outer side matching position can play a reliable anti-loosening role. The length of the fastening deformation matching groove 7 is greater than half the height of the main body matching connection column 2, ensuring that the safety during the anti-loosening cooperation is more reliable. It can ensure that the fastening position has a reliable anti-loosening effect by integrating an isolation structure on the main structure and coordinating the deformation groove set at the fastening position and the welding matching stabilization groove when fastening. When fastening internally, the outer side can be expanded outward, so that the outer side has a better anti-loosening effect. The welding matching stabilization groove can also be used as a matching structure during welding, which can ensure better internal welding firmness, more reliable anti-loosening stability during welding, and better durability during later use.
[0021] Preferably, a matching guide groove is provided at the upper edge of the matching connection hole 4 of the main body, so that the matching operation when combined with the riveting machine during riveting is more convenient.
[0022] Preferably, the height of the main body fitting connection column 2 is the same as the length of the fastening deformation fitting groove 7, the fitting space of the overall fastening position is larger, and the overall anti-loosening stability after fastening can be further improved.
[0023] Preferably, the lower end of the riveted fitting connection seat 3 is a conical surface, and a riveted sealing fitting safety groove is provided at the connection position between the conical surface and the main isolation support column 1. When riveting, it can ensure better tightness when fitting with the edge position of the hole position of the riveted plate, and the fitting firmness of the riveted position is more reliable.
[0024] Preferably, the lower end edge of the main body and the connecting column 2 is provided with a chamfered structure for convenient installation and assembly, so that the fitting operation in later use is more convenient and the fitting and connection operation is smoother.
[0025] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or replacements can be made without departing from the principles described in the present invention. These improvements or replacements should also be regarded as the scope of protection of the present invention.
