Embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
With reference to Fig. 1, the utility model fan fixer comprises fan frame 20, plastic stud 30 and the casing 10 in order to fan attachment.Plastic stud 30 is "T"-shaped setting, and ailhead is "T"-shaped lateral part, and the nail body is "T"-shaped vertical part.Fan frame 20 is provided with first location hole 201.Casing 10 is provided with second location hole 101 corresponding with first location hole, 201 positions.The nail body back-off shape of plastic stud 30 is provided with, and button length equates substantially with the outer face distance of second location hole and 101 first location holes 201, can pass second location hole 101 and first location hole 201 successively, can fan frame 20 is fixing with casing 10.In one embodiment, the aperture of second location hole 101 can equate with first location hole 201.
With reference to Fig. 2, be the detailed structure schematic diagram of plastic stud among Fig. 1 30.The nail body of this plastic stud 30 comprises at least two elastic clasps 301.In one embodiment, the quantity of elastic clasp 301 can make symmetrically arranged two, also can be more than three or three.Elastic clasp 301 can be divided equally the nail body, and promptly following closely body can be made of two or more elastic clasps.Particularly, the coupler body of elastic clasp 301 outwardly, several elastic clasp 301 formed external diameters are greater than the aperture of first location hole 201 on the nail body.The coupler body top is provided with inclined-plane 3011, conveniently to pass first location hole 201.During through first location hole 201, the inclined-plane, coupler body top 3011 and first location hole 201 are interfered, elastic clasp 301 inwardly shrinks, after passing first location hole 201, the coupler body resilience, the hook plane is fastened on the plane, bottom of first location hole 201, and the coupler body bottom face is fitted on the plane, top of second location hole 101, fixedlys connected with casing 10 thereby will fan frame 20.Among this embodiment, the state after fan frame 20, plastic stud 30 and casing 10 assemblings can be with reference to Fig. 3 and shown in Figure 4.
With reference to Fig. 5 to Fig. 8, in one embodiment, also flange 21 can be set in the tip edge of first location hole 201, accordingly, nail body at above-mentioned plastic stud 30 is provided with the symmetrical flat side 302 of sealing, and this initiating terminal that seals flat side 302 can be arranged on the ailhead bottom surface, and its length is the length of aforementioned button.Sealing flat side's 302 not-go-end plane can join work with flange 21, and for example its degree of depth can be more than or equal to the outstanding length of flange 21 with respect to first location hole, 201 inwalls.The nail body is during through first location hole 201, and flange 21 will be strutted, and after following closely the body front end and passing first location hole 201, flange 21 retractions fasten with the flat side's 302 of sealing not-go-end plane 3021.
