Have among the figure: backboard 1, plastic cement frame 2, trip 3, draw-in groove 4, distortion groove 5, lug 6.
The specific embodiment
Below in conjunction with accompanying drawing, the technical scheme of the utility model is carried out detailed explanation.
To shown in Figure 5, a kind of snap fastener that is used for module dorsulum backlight and plastic cement frame of the utility model comprises backboard 1, plastic cement frame 2, trip 3, draw-in groove 4 and distortion groove 5 like Fig. 3.Trip 3 is positioned at the side of backboard 1.Draw-in groove 4 and distortion groove 5 are positioned at the same side of plastic cement frame 2, trip 3 dismountable being fixed in the draw-in groove 4.
During installation, directly can accomplish being connected of module dorsulum backlight and plastic cement frame in the trip 3 insertion draw-in grooves 4 with backboard 1.When the size of fluting 4 size less than trip 3, when trip 3 can't directly insert in the draw-in groove 4,, the size of draw-in groove 4 is enlarged through crimp groove 5, make trip 3 can stretch in the draw-in groove 4.Moving of trip 3 in the draw-in groove 4 restriction insertion draw-in grooves 4 is fixed in the draw-in groove 4 trip 3.When needs are dismantled, directly trip 3 is extracted out from draw-in groove 4.In the snap fastener of this structure, trip 3 is arranged on the side of backboard 1, and draw-in groove 4 is arranged on the side of plastic cement frame 2.Trip 3 all is not positioned on two sides with draw-in groove 4 simultaneously.Just be difficult for producing the space between backboard after installing like this and the plastic cement frame.Location between backboard and the plastic cement frame is just very firm, can not produce the escape phenomenon, thereby improve the qualification rate of module product backlight.
Further, described draw-in groove 4 is " U " shape, on the inwall of draw-in groove 4 both sides, is provided with relative a pair of lug 6.The shape of draw-in groove 4 can be various, but be good with " U " shape." U " shape draw-in groove 4 is made the size that can conveniently regulate draw-in groove 4 on the other hand on the one hand easily.On the inwall of draw-in groove 4 both sides, be provided with a pair of lug 6.Lug 6 can prevent that trip 3 from shifting out from the openend of draw-in groove 4 to inserting trip 3 location in the draw-in groove 4.The cross section of described lug 6 is good to be arc surface, and the distance between two lug 6 tops is 4/5ths of trip 3 diameters.Can guarantee certain amount of interference like this, be convenient to engage or take out operation again.
Further, trip 3 is cylinder.The shape of trip 3 can be various, is good with cylinder still.See on the cross section: the anchor point of cylindrical trip 3 in draw-in groove 4 is three points, and wherein, a point is positioned on draw-in groove 4 inwalls, and all the other two points lay respectively on two lugs 6.Therefore, the location of cylindrical trip 3 in draw-in groove 4 is more firm.Certainly, on manufacturing process, cylindrical trip 3 also is very easy to make.
Further, described trip 3 contacts with two lugs 6 with the top of draw-in groove 4 in draw-in groove 4, forms three contact points, and the diameter of a circle that these three contact points constitute is with the equal diameters of trip 3.For easy for installation, to avoid being out of shape groove 5 and produce excessive size distortion, the diameter of trip 3 is equal with the diameter of a circle that is made up of the contact point of trip 3 in draw-in groove 4.Like this, when mounted, draw-in groove 4 is as long as distortion a little can make trip 3 insert in the draw-in groove 4.
Further, described distortion groove 5 is two, is positioned at the both sides of draw-in groove 4.In order to guarantee that trip 3 can insert in the draw-in groove 4, arrange a distortion groove 5 respectively in the both sides of draw-in groove 4.Like this, on the one hand draw-in groove 4 has enough size variables, and on the other hand when draw-in groove 4 produces deformation, draw-in groove 4 is simultaneously to the distortion groove 5 generation extruding forces of both sides, whole plastic cement frame 2 stressed more even.
The core of the utility model is, through on a side of backboard 1, trip 3 being set, draw-in groove 4 and distortion groove 5 is set on a side of plastic cement frame 2, makes when trip 3 is fixed in the draw-in groove 4, can not produce the space between plastic cement frame 2 and the backboard 1.The content of the above-mentioned specific embodiment only is the explanation to the present technique scheme.The non-creativeness that any those skilled in the art carry out according to the present technique scheme improves, and all belongs to the protection domain of this patent.
