DETAILED DESCRIPTION

[0019] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0020] Example

[0021] like Figure 1-4 As shown, a fan frame assembly structure includes a front cover 1 and a rear cover 2, the front cover 1 includes a cover plate 11, an end face buckle 3 and two side buckles 4, the rear cover 2 is provided with an end face embedding groove 5 and a side end embedding groove 6 corresponding to the end face buckle 3 and the side buckle 4, the end face embedding groove 5 and the side end embedding groove 6 are both provided with locking teeth 7, and the rear cover 2 is also provided with a plurality of locking ears 8.

[0022] The end face buckle 3 and the two side buckles 4 have the same structure and are an integrally formed structure with the cover plate 11. Locking grooves 9 are provided on the end face buckle 3 and the two side buckles 4. The locking grooves 9 are matched and connected with the locking teeth 7. The end face buckle 3 and the two side buckles 4 are formed by bending from the cover plate 11 toward the rear cover 2. The locking grooves 9 are rectangular in shape, and the locking teeth 7 are inserted into the locking grooves 9 for locking.

[0023] The end face embedding groove 5 has a buckle surface 51, and the front end of the buckle surface 51 has an extended boss 52. The height of the end face embedding groove 5 is less than the height of the end face buckle 3. Two slots 10 are provided at the connection between the front cover 1 and the end face buckle 3. The slots 10 are respectively arranged on both sides of the end face buckle 3, and the slots 10 are arranged corresponding to the extended boss 52. The extended boss 52 extends from the front end of the cross-sectional embedding groove 5. When the end face buckle 3 is inserted into the locking groove 9, the end face buckle 3 is fitted with the buckle surface 51, and the extended boss 52 is inserted into the slot 10 for positioning. The front cover 1 and the rear cover 2 are locked in the vertical direction by the extended boss 52.

[0024] The locking tooth 7 has a first contact surface 71, a second contact surface 72 and a rear end buckling surface 73. The first contact surface 71 is an inclined surface and is arranged close to the front cover 1. The end face buckle 3 slides along the first contact surface 71 to the second contact surface 72, and finally falls into the buckle surface 51 and is clamped with the rear end buckling surface 73. The locking tooth 7 is used to lock and fix the end face buckle 3 in the horizontal direction.

[0025] A convex edge 12 is provided at the front end of the rear cover 2, and the cover plate 11 is embedded in the convex edge 12. The embedded structure of the front cover 1 keeps the rear end surface of the front cover 1 and the rear cover 2 in a flat state after assembly, which can ensure the structural strength after assembly and the aesthetic appearance of the fan frame.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments or replace some of the technical features therein by equivalents.
