[0030] Embodiment

[0031] According to a snap - on installation structure provided by the present utility model, as Figures 1 - 3As shown in the figure, it includes: a bracket 1 and a fan 2. The bracket 1 is provided with an integrally formed buckle mounting component. The bracket 1 is provided with a fan mounting groove. The fan 2 is connected to the fan mounting groove of the bracket 1 through the buckle mounting component. The buckle mounting component includes a radial limiting rib, an axial limiting rib, and a cantilever barb structure. The axial limiting rib and the radial limiting rib are respectively installed on both sides of the fan mounting groove. The cantilever barb structure clamps the fan 2. The fan 2 is limited in the radial direction by the radial limiting rib, and the fan 2 is limited in the axial direction by the axial limiting rib. The end of the cantilever barb structure is provided with a barb structure, and the barb structure is in interference fit with the fan 2 to clamp the fan and prevent the fan from coming out. The cantilever barb structure is made of an elastic material, and there should be a certain interference amount between the cantilever surface and the fan mating surface to ensure reliable positioning. The radial limiting rib and the axial limiting rib are rigid, and there should be a gap between the radial limiting rib and the axial limiting rib and the fan 2 to prevent assembly difficulties caused by part tolerances. In the assembled state, the axial and radial limiting ribs are in zero contact with the fan, so that the fan is in an absolute position and does not move. There is a certain interference amount between the cantilever barb structure and the fan 2. Through the elastic property of the barb structure, the barb structure tightly presses the fan to ensure the fan is locked.

[0032] The cantilever barb structure includes a first cantilever barb structure 501, a second cantilever barb structure 502, and a third cantilever barb structure 503. The first cantilever barb structure 501 and the third cantilever barb structure 503 are symmetrically distributed on the two side walls in the vertical direction of the bracket 1. The ends of the first cantilever barb structure 501 and the third cantilever barb structure 503 are respectively pressed against both sides of the fan 2 through the barb structure to fix the radial direction of the fan 2. The cantilever structure 1 and the cantilever structure 3 are elastic structures. During installation, first open the cantilever structure 1 and the cantilever structure 3 to both sides to slide the fan 2 into the inside of the buckle mounting structure. The second cantilever barb structure 502 is installed on the top of the bracket 1, and the second cantilever barb structure 502 is pressed against the top of the fan 2 through the barb structure. Preferably, the fan 2 is axially fixed through the cooperation of the fourth axial limiting rib 404 and the second cantilever barb structure 502.

[0033] The axial limiting ribs include a first axial limiting rib 401, a second axial limiting rib 402, a third axial limiting rib 403, and a fourth axial limiting rib 404. The first axial limiting rib 401 and the third axial limiting rib 403 are located on both sides of the front end of the top of the fan mounting groove. The second axial limiting rib 402 and the fourth axial limiting rib 404 are located on both sides of the front end of the bottom of the fan mounting groove.

[0034] The radial limiting ribs include a first radial limiting rib 301, a second radial limiting rib 302, a third radial limiting rib 303, a fourth radial limiting rib 304, a fifth radial limiting rib 305, and a sixth radial limiting rib 306. The first radial limiting rib 301 and the fifth radial limiting rib 305 are respectively located on both sides of the front end of the top of the fan mounting groove, and the second radial limiting rib 302 and the sixth radial limiting rib 306 are located on both sides of the front end of the bottom of the fan mounting groove. The first radial limiting rib 301 is located below the first axial limiting rib 401, the second radial limiting rib 302 is located above the second axial limiting rib 402, the fifth radial limiting rib 305 is located below the third axial limiting rib 403, and the sixth radial limiting rib 306 is located above the fourth axial limiting rib 404.

[0036] Working principle: When the fan 2 is pushed in, the first cantilever barb structure 501, the second cantilever barb structure 502, and the third cantilever barb structure 503 need to undergo a certain amount of elastic deformation. The entire pushing process is limited by the first radial limiting rib 301, the second radial limiting rib 302, the fifth radial limiting rib 305, the sixth radial limiting rib 306, the first axial limiting rib 401, the second axial limiting rib 402, the third axial limiting rib 403, and the fourth axial limiting rib 404. When the fan 2 contacts the third radial limiting rib 303 and the fourth radial limiting rib 304, at this time, the first cantilever barb structure 501, the second cantilever barb structure 502, and the third cantilever barb structure 503 clamp the fan tightly by elastic deformation.
