[0019] like Figures 1 to 8As shown, a fan seal matching component includes a cylindrical main body matching stabilizing column 1, the upper end of the main body matching stabilizing column 1 is provided with an integrally formed conical connection seal matching column 2, the upper end of the connection seal matching column 2 is an integrally formed transition matching connecting column 3, and the upper end of the transition matching connecting column 3 is provided with a main body matching conveying hole 4 that penetrates the lower end of the whole, which is a main air duct structure. The outer side of the connection seal matching column 2 is provided with a first seal matching groove 5 with a V-shaped cross section at the connection position with the main body matching stabilizing column 1, and the outer side of the connection seal matching column 2 is provided with a second seal matching groove 6 with a L-shaped cross section at a position above the plane where the upper end surface of the main body matching stabilizing column 1 is located, which can be matched with the installation hole position of the fan housing for sealing matching during matching, and double complementary sealing matching is achieved through the matching of two sets of sealing rings. The right side of the main body matching stabilizing column 1 and the connection seal matching column 2 is provided with a limit stable matching groove 7 that is communicated with the inside, which can be associated with the limit structure of the installation position, and the matching stability during connection is better. The two angle positions at the upper end of the limit-stabilizing matching groove 7 are respectively provided with cylindrical sealing and anti-loosening matching holes 8. When the overall matching installation is performed, this position can provide a precise and safe matching position for the sealant, ensuring better sealing firmness at the connection position. The sealing and anti-loosening matching hole 8 connects the inner and outer sides of the connecting sealing matching column 2. It adopts a brand-new structural design. By setting a limit matching structure on the side, it can be limited and associated with the main structure of the fan during installation. The outer position ensures the tightness of the matching with the fan casing by setting two combined sealing structures that cooperate with each other. The sealing and anti-loosening matching hole is set at the matching position of the limit structure. After assembly, it can be more safely and tightly set with the sealant, ensuring better overall sealing of the matching position, better sealing safety during later use, and higher overall combination efficiency during installation.
[0020] Preferably, both sides of the lower end of the position-limiting stable matching groove 7 are provided with chamfered structures for easy matching, so that the operation during matching and placement is more convenient, and the lower end position has a matching avoidance function.
[0021] Preferably, the upper and lower sides of the main body matching delivery hole 4 are respectively provided with sealing matching connection grooves to ensure better sealing of the edge position when assembled and higher air duct safety when in use.
[0022] 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 substitutions can be made without departing from the principles of the present invention. These improvements or substitutions should also be regarded as the protection scope of the present invention.
