DETAILED DESCRIPTION

[0023] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Embodiment: A centrifugal fan mounting frame, see Figure 1-Figure 6As shown, it includes a fixing plate 1, a connecting plate 2, a supporting plate 3, a fixing member 4, a connecting member 5, a screw 6, a stabilizing plate 7, a protective ring 8, a fan body 9, a fixing frame 10, a threaded rod 11, a supporting seat 12, a shock-absorbing pad 13, an isolation plate 14, a ventilation plate 15 and a gear lever 16. The connecting plate 2 is welded symmetrically between the front and rear sides of the fixing plate 1. The upper part of the fixing plate 1 is installed with the supporting plate 3 through the connecting member 5, and the upper part of the connecting plate 2 on the left side is also installed with the supporting plate 3 through the connecting member 5. The middle part of the fixing plate 1 is provided with fixing grooves 41 on both the front and rear sides, and the bottom of the connecting plate 2 is also provided with fixing grooves 41. The fixing member 4 is installed in the fixing groove 41. The support plate 3 is spaced apart with installation grooves 61, and the installation grooves 61 are detachably installed with screws 6. The bottoms of the fixing plate 1 and the connecting plate 2 are both connected with stabilizing plates 7. The stabilizing plate 7 is used to enhance the stability of the device. A protective ring 8 is connected to the left side of the left support plate 3. A fan body 9 is installed between the two support plates 3 by screws 6. The screws 6 facilitate the installation and disassembly of the fan body 9. A fixing frame 10 is installed on the upper right side of the fixing plate 1 by a threaded rod 11. The fixing frame 10 is arranged in a trapezoidal shape. Support seats 12 are welded to the front and rear sides of the top of the fixing frame 10 by bolts. The support seat 12 holds the motor on the right side of the fan body 9. A shock-absorbing pad 13 is connected to the top of the support seat 12. The shock-absorbing pad 13 is used to reduce shock for the motor. An isolation plate 14 is welded to the left side of the left support plate 3. A ventilation plate 15 is connected to the inner side of the isolation plate 14. The ventilation plate 15 can filter the blown air. A gear lever 16 is evenly spaced and detachably installed between the ventilation plate 15 and the left support plate 3.

[0025] When the device needs to be used, people first fix the fan body 9 between the two support plates 3 by screws 6, so that the ventilation plate 15 blocks the left side of the fan body 9, and the protective ring 8 can protect the fan body 9, and the motor is installed on the right side of the fan body 9, so that the motor is placed on the support seat 12.
