Embodiment 1

[0045] See figure 1 , the front casing of the axial flow fan in the first embodiment includes a wind guide cover 10 and a second frame 11 . figure 1 A first frame 101 is formed on the middle wind deflector 10 . Wherein the first frame 101 and the outlet grille on the air guide cover 10 can be integrally formed or independently formed.

[0046] figure 1 Among them, the first frame 101 and the second frame 11 are circular (more strictly speaking, the first frame 101 and the second frame 11 are ring-shaped, and in this application document, the shapes of the first frame 101 and the second frame 11 are identified When ignoring its cross-sectional size, we get figure 1 The first frame 101 and the second frame 11 are circular). Of course, with figure 1 There is no restriction on the wind guide cover 10 and the second frame 11 . For example, the first frame 101 and the second frame 11 may also be rectangular. For another example, both the first frame 101 and the second frame 1...

Embodiment 2

[0060] The difference from the first embodiment is that in the second embodiment, the elastic buckle 13 is deformed along the extending direction of the frame corresponding to the installation hole 12 .

[0061] When the first frame 101 is in the shape of a ring, the deformation direction of the elastic buckle 13 is also the tangential direction of the first frame 101 . When the first frame 101 is rectangular, the deformation direction of the elastic buckle 13 is also the length direction of the frame of the first frame 101 .

[0062] In the second embodiment, the rectangular first frame 101 is taken as an example for illustration, and the first frame 101 includes a first frame and a second frame that are perpendicular to each other. When the first frame is equipped with an elastic buckle 13 deformed along its own length direction, and the second frame is also equipped with an elastic buckle 13 deformed along its own length direction, it means that the first frame is matched w...

Embodiment 3

[0066] The difference from Embodiment 1 and Embodiment 2 is that in Embodiment 3, the number of the elastic buckles 13 is multiple, and the deformation direction of some of the elastic buckles 13 is perpendicular to the corresponding mounting holes 12 In the extending direction of the frame where the mounting hole 12 is located, the remaining elastic buckle 13 is deformed along the extending direction of the frame where the mounting hole 12 is located.

[0067] For example, for the ring-shaped first frame 101, if only the elastic buckle 13 whose deformation direction is perpendicular to the extension direction of the frame where the mounting hole 12 is located is provided, then the second frame 11 will be in the radial direction of the first frame 101. There is slight movement. On this basis, by providing the elastic buckle 13 deformed along the extension direction of the frame where the mounting hole 12 is located, the above play can be eliminated.

[0068] Of course, for th...

Abstract

The invention relates to the technical field of axial flow fan shell assembling, and provides a frame assembly for a front shell of an axial flow fan and an axial flow fan shell. The frame assembly for the front shell of the axial flow fan comprises a first frame which is used for mounting an air outlet grille, and a second frame which is matched with the first frame and protects the first frame;mounting holes are formed in the first frame; first elastic clamping buckles which are matched with the mounting holes are arranged on the second frame; and the first elastic clamping buckles are extruded to deform and enter the mounting holes, and are clamped on the back surface of the first frame after deformation restores. The second frame is arranged on the first frame, so that the structureswhich are mounted on the first frame can be prevented from being exposed; and therefore, a protective effect is achieved on the structures which are mounted on the first frame. In addition, the secondframe can also achieve a decorating effect. Moreover, the first frame and the second frame are quick in production line assembly and firm in structures; and the requirements on the structures and themanufacturing complexity of the first frame and the second frame are low, and moulds are easy to manufacture and low in cost, so that the frame assembly for the front shell of the axial flow fan andthe axial flow fan shell can be widely popularized.

Description

technical field [0001] The invention relates to the technical field of axial flow fan casing assembly, in particular to a frame assembly for an axial flow fan front casing and an axial flow fan casing. Background technique [0002] At present, when the two components on the casing of the axial flow fan are assembled and matched, especially for the assembly and cooperation of the annular components, they are limited to rotation buckling and screw fixing. However, rotary fastening and screw fixing have high requirements on the components themselves, such as the strength of the material of the components, the shape of the components themselves, the machining accuracy of the components, the development of component processing molds and the assembly space, which are difficult to promote on a large scale. . Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0004] One of th...
