[0020] As Figures 1 to 7 shown, a fiberglass centrifugal fan assembly auxiliary device includes a first main body support and mating seat 1 whose projection in the front-back direction is an isosceles trapezoid. The interior of the first main body support and mating seat 1 is a hollow structure. At the upper end position inside the first main body support and mating seat 1, there is an integrally formed combined stable connection column 2 with a downward direction to ensure the overall strength of the internal structure is more stable. At the upper end of the first main body support and mating seat 1, there is a mating placement combined groove 3 that communicates with the internal hollow structure. The mating placement combined groove 3 is a V-shaped structure with an upward opening to make the combined strength at the mating position better. On the left and right sides of the mating placement combined groove 3, there are mating placement stable connection grooves that are evenly distributed up and down and whose sizes increase sequentially from bottom to top. At the position of the mating placement combined groove 3, there is a second main body support and mating seat 4, and they form the main structure of this device. The upper end of the second main body support and mating seat 4 is a mating reference horizontal plane. On the left and right sides of the lower end of the second main body support and mating seat 4, there are combined stable mating columns that mate with the mating placement stable connection grooves to ensure stronger overall bearing capacity during combination. At the lower end of the second main body support and mating seat 4, near the upper end position of the first main body support and mating seat 1, there is an arc-shaped main body avoidance and mating safety groove 5 to ensure better smoothness of the mating during combination, larger space at the operation position during the movement operation and mating, and more convenient operation. It adopts a brand-new structural design. The main structure is composed of two mutually cooperating combined structures. When in use, the upper end position can be used as the placement reference plane for the rear components during the assembly of the fiberglass centrifugal fan, and it can replace manual support and mating during installation. Its lower end position has a certain deformation space. During installation, it can make the alignment of the installation position more convenient, higher cooperation efficiency during operation, no need for manual direct hand-held operation, better overall safety during the assembly process. The upper end position of this device is connected by a sliding fit in the front-back direction. During use, it can be flexibly slid in the front-back direction as needed, with stronger flexibility during the auxiliary assembly, and can effectively improve the convenience during the assembly of the fiberglass centrifugal fan.

[0021] Preferably, the interior of the mating placement stable connection groove is an arc-shaped structural surface, with a larger combined area and better mating stability during mating.

[0022] Preferably, one side of the second main body support and mating seat 4 extends beyond the side area of the upper end position of the first main body support and mating seat 1, making the occupied space at the upper end smaller and more convenient during mating.

[0023] Preferably, the projection of the second main body support fitting seat 4 in the up-and-down direction does not exceed the area of the projection of the first main body support fitting seat 1 in the up-and-down direction, so that the overall structure occupies relatively less space, has better fitting safety during use, and more stable bearing capacity.

[0024] Preferably, the length of the first main body support fitting seat 1 in the front-and-back direction is the same as the length of the second main body support fitting seat 4 in the front-and-back direction, so that the overall combination stability during combined use is better, and the stability during auxiliary fitting installation is more reliable.

[0025] The above are the preferred embodiments 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.
