DETAILED DESCRIPTION

[0031] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and a specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0033] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0034] In the following embodiments, unless otherwise specified, functional components or structures are conventional components or conventional structures used in the art to achieve corresponding functions.

[0035] Embodiment 1:

[0036] like Figure 1-3As shown, a stabilizing device for a motor fan comprises: a first stabilizing plate 1-1 with a first guide hole 2-1 in the center; a second stabilizing plate 1-2 with a second guide hole 2-2 in the center and connected to the first stabilizing plate 1-1, the second guide hole 2-2 and the first guide hole 2-1 are concentric circles connected and used for the motor fan rotor shaft to pass through, the diameter of the first guide hole 2-1 is larger than the diameter of the second guide hole 2-2; the second stabilizing plate 1-2 is provided with a cylindrical pin 4 for positioning the motor fan base, a fixing component 5 for fixing the second stabilizing plate 1-2 and the motor fan base, and a disassembly hole 6 for disassembly on a side close to the first stabilizing plate 1-1, the cylindrical pin 4, the fixing component 5, and the disassembly hole 6 satisfying that the projection of the second guide hole 2-2 as the center and perpendicular to the first stabilizing plate 1-1 is located in the first guide hole 2-1; a plurality of balancing blocks 7 are provided on the edge of the second stabilizing plate 1-2 away from the first stabilizing plate 1-1.

[0037] The purpose of this technical solution is to locate the position of the motor fan rotor on the motor fan base and make the motor fan rotor balanced and stable. The first stabilizing plate 1-1 and the second stabilizing plate 1-2 are fixed on the motor fan base as connecting parts of the motor fan rotor. Specifically, they are positioned on the motor fan base through cylindrical pins 4 and fixed through fixing components 5. At the same time, the balancing block 7 on the second stabilizing plate 1-2 provides a balancing force for the motor fan rotor. In addition, to facilitate the disassembly of the stabilizing device, a disassembly hole 6 is also provided on the second stabilizing plate 1-2.

[0038] In order to strengthen the connection relationship between the first stabilizing plate 1-1 and the second stabilizing plate 1-2, in this embodiment, a plurality of support frames 3 corresponding to the edges of the first guide holes 2-1 are provided on one side of the second stabilizing plate 1-2 close to the first stabilizing plate 1-1, and the support frames 3 are used to fix the first stabilizing plate 1-1 and the second stabilizing plate 1-2.

[0039] In order to strengthen the fixing function of the present stabilizing device, in this embodiment, the second stabilizing plate 1-2 is provided with a plurality of fixing holes 8 for the fixing assembly 5 to pass through, and the fixing assembly 5 includes a bolt 5-1 passing through the fixing hole 8 and used to fix the second stabilizing plate 1-2 and the motor fan base, and a stopper 5-2 provided between the fixing hole 8 and the head of the bolt 5-1 and used to limit the position of the bolt 5-1. The stopper 5-2 is an integrally formed L-shaped structure, including a first stopper section abutting against the fixing hole 8 and a second stopper section abutting against the edge of the head of the bolt 5-1. For example, in actual operation, when the bolt 5-1 is a hexagonal bolt, after one end of the screw rod of the hexagonal bolt passes through the stop plate 5-2 and the fixing hole 8 in sequence and is fixed to the motor fan base, the stop plate 5-2 at the edge of its head is folded close to the head of the hexagonal bolt, and the folded part is the second stop section, and the folded part is the first stop section, which is used to press against the hexagonal bolt through the second stop section to prevent the hexagonal bolt from loosening.

[0040] In this embodiment, the cylindrical pin 4 and the fixing assembly 5 are located on the same arc. Preferably, the cylindrical pins 4 are provided with 3, and the fixing assemblies 5 are provided with 6, wherein one of the cylindrical pins 4 is provided between two of the fixing assemblies 5, and the three cylindrical pins 4 also form a stable triangular structure, thereby improving the positioning relationship between the stabilizing device and the motor fan base. Exemplarily, in actual operation, the motor fan rotor and the motor fan base are first matched, and a notch is opened on the motor fan base, and the cylindrical pin 4 on the second stabilizing plate 1-2 is positioned at the corresponding notch on the motor fan base, and the second stabilizing plate 1-2 and the motor fan base are fixed by the fixing assembly 5.

[0041] In this embodiment, two disassembly holes 6 are provided, which are symmetrically arranged on the second stabilizing plate 1-2 with the second guide hole 2-2 as the center. For example, in actual operation, by inserting a steel bar into the two disassembly holes 6, the stabilizing device is disassembled from the motor fan base by pulling.

[0042] In this embodiment, the arc diameter of the disassembly hole 6 is smaller than the arc diameter of the cylindrical pin 4, so that the force applied when the steel bar is inserted into the disassembly hole 6 for disassembly is greater than the force applied to fix the second stabilizing plate 1-2 to the motor fan base.

[0043] In this embodiment, a guide tube 9 is provided along the edge of the first guide hole 2-1 on the side of the first stabilizing plate 1-1 away from the second stabilizing plate 1-2. The guide tube 9 is integrally formed with the first stabilizing plate 1-1 to facilitate the motor fan rotor shaft to pass through the first stabilizing plate 1-1 and the second stabilizing plate 1-2.

[0044] Embodiment 2:

[0045] like Figure 4 As shown, compared with Example 1, most of them are the same, the difference is that a notch is also provided at the edge of the second guide hole 2-2, and the notch is used to locate the corresponding protrusion position on the motor fan base to avoid secondary correction of the stabilizing device after disassembly and reinstallation.

[0046] The above description of the embodiments is to facilitate the understanding and use of the utility model by those skilled in the art. It is obvious that those familiar with the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the utility model is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the utility model without departing from the scope of the utility model should be within the scope of protection of the utility model.
