The specific embodiment
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
Preferred embodiment one:
The screw fastening structure that this preferred embodiment proposes a kind of screw stiffener and is made up of this screw stiffener.As shown in Figure 1 and Figure 4, this screw stiffener comprise end face 1, four supporting surfaces 2 being bent to form downwards along the edge of end face 1 and be arranged on the through hole 3 on end face 1.End face 1 is inclined plane, and the screw thread on the gradient of end face 1 and incline direction and screw is suitable,
End face 1 is cross, and four terminations are bent to form respectively supporting surface 2 downwards.Wherein, the end of two supporting surfaces 2 forms flange 21, and flange 21 is for being pressed on refrigerator courage lateral surface.The outside of end face 1 is rectangle substantially.
Installation portion on recess and parts to be installed on screw stiffener, refrigerator courage forms screw fastening structure jointly.
As shown in Figure 2 and Figure 4, refrigerator courage 5 is provided with recess 51, and on the lateral surface of refrigerator courage 5, corresponding recess 51 places form protuberance 52.The madial wall of recess 51 is rectangle, and is provided with for determining that screw penetrates the screw location pit 53 of refrigerator courage 5 positions on the bottom surface of recess 51.
As shown in Figure 3 and Figure 4, on parts to be installed, be provided with installation portion 41.On installation portion 41, the position of the through hole 3 of corresponding screw stiffener is provided with installing hole 42, and installing hole 42 outsides are provided with two convex tendons 43.Two convex tendons 43 are symmetrical arranged centered by installing hole 42, for preventing that installation portion 41 from rotating in rectangular recess 51 inner sides, makes installation portion 41 be positioned at better in recess 51.
Using method: as shown in Figure 4, select thinner material (thickness is about the distance between adjacent two teeth middle part of screw) processing to obtain screw stiffener, screw stiffener is buckled on the protuberance 52 in refrigerator courage 5 outsides, through hole 3 aligns with screw location pit 53.The installation portion of parts to be installed 41 is placed on to the recess 51 of refrigerator courage 5 inner sides, installing hole 42 aligns with screw location pit 53.Screw in from installing hole 42 with a screw, screw location pit 53 is worn on top.Screw continues propelling and is screwed in through hole 3, and the through hole 3 at inclined top surfaces 1 place forms a screw buckle, blocks screw (forming the effect identical with nut).
Preferred embodiment two:
The screw fastening structure that this preferred embodiment proposes a kind of screw stiffener and is made up of this screw stiffener, its structure and preferred embodiment one are basic identical.Four supporting surfaces that this screw stiffener comprises end face, be bent to form downwards along the edge of end face and be arranged on the through hole on end face.Installation portion on recess and parts to be installed on screw stiffener, refrigerator courage forms screw fastening structure jointly, and installation portion is set in recess, and screw stiffener is enclosed within the outside of protuberance.
Difference is: the thickness of making the material of screw stiffener is not limit, can be thin material through hole 3 form a screw buckle, can be also that thicker material will be prepared screw thread in the later stage in through hole 3; The concrete shape of screw stiffener is not limit, and can effectively support, not relatively rotate with refrigerator courage 5 outsides and protuberance 52; Screw stiffener end face can be tilt can be also flat; The madial wall of recess is not limited to rectangle, can be non-circular other shape, avoids, between screw stiffener and the recess on protuberance and refrigerator courage on refrigerator courage and the installation portion on parts to be installed, relative rotation occurs; The lateral profile concrete shape of installation portion is not limit, can be suitable with the inner side profile of recess.
