[0020] like Figures 1 to 7As shown, a centrifugal fan support frame assembled reinforcement structure includes two main support stabilization plates 1 distributed front and back. The front and rear main support stabilization plates 1 are both tilted toward the center position in the front-to-rear direction. The angle between the front and rear main support stabilization plates 1 is 12 degrees, which can ensure that the main structure has reliable bearing capacity during use. The 12-degree angle can ensure better stability during cooperation. The left and right sides of the main support stabilization plate 1 are combined together by a support limit cooperation plate 2. The left and right sides of the main support stabilization plate 1 are respectively provided with a combination insertion cooperation plate 4. The main support stabilization plate 1 is combined with the combination groove provided on the support limit cooperation plate 2 through the combination insertion cooperation plate 4, which is more convenient during use and makes them combined for use. When not in use, it occupies less space and is easier to store. The lower ends of the support limit cooperation plate 2 and the main support stabilization plate 1 are both provided with a downward-opening avoidance cooperation safety groove 3, which provides more space at the lower end position, making it more convenient for the overall cooperation of the centrifugal fan in the later stage. The upper end of the support and limit fitting plate 2 is an inclined placement stable support groove 5, which has better placement stability when the upper end is matched with the fan body, and can play a role in placement positioning, making the placement stability better. The upper end of the support and limit fitting plate 2 is located in front of the placement stable support groove 5 and is provided with an integrally formed limit fitting safety boss 6, which can play a role in limit fitting, ensuring better placement fitting strength and more reliable fitting safety. The limit fitting safety boss 6 and the placement stable support groove 5 are connected together through an inclined inclined surface structure transition, which makes the fitting position space larger and the fitting stability more reliable during fitting. When in use, it can be matched and connected on the basis of the existing base, and can be matched with the welding structure inside the bottom by welding on both sides, which can effectively reinforce the base body, and in the later stage, when matched with the centrifugal fan body, the limit structure at the upper end position can be accurately matched and placed, which can effectively improve the support strength of the fan body when matched and placed, and improve the safety during matching, and the safety of the centrifugal fan is more reliable during installation and use.

[0021] Preferably, the shape of the avoidance safety groove 3 is a trapezoidal structure, which can ensure better overall structural support strength, longer service life during use, and more reliable strength when used in conjunction with support.

[0022] Preferably, the length of the combined insert fitting plate 4 at the rear position is greater than the length of the combined insert fitting plate 4 at the front position, so that the support strength at the rear position is higher, the bearing capacity is stronger when used in combination, and the safety of use can be further improved.

[0023] Preferably, the length direction of the combined insert fitting plate 4 is the same as the length direction of the main body support stabilization plate 1, and the thickness of the main body support stabilization plate 1 is the same as the thickness of the combined insert fitting plate 4, so that they are more flat and the cost during production and processing is lower.

[0024] Preferably, the lower end of the main support stabilization plate 1 and the lower end of the support limit matching plate 2 are on the same plane, and an anti-slip limit matching groove is provided on the lower end surface of the support limit matching plate 2. When the overall fan product is installed and placed in the later stage, it can be placed and matched as a stable matching structure, so that the overall placement stability is better and the safety during use is higher.

[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 substitutions can be made without departing from the principles described in the present invention. These improvements or substitutions should also be regarded as the scope of protection of the present invention.
