The specific embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
See also Fig. 1 to Fig. 7, the locker that the embodiment of the invention provides comprise in order to set battery (figure do not show) or/and the housing 12 of SD card (figure does not show) and place said housing 12 tops with battery or/and SD card 40 covers at the cards lid 14 in the said housing 12.Battery compartment 10, SD bayonet socket 40 and USB interface hole 11 have been shown among the figure.Said card lid 14 has first end 15 and second end 16.The top of first end 15 of said card lid 14 offers storage tank 17.Second end 16 of said card lid 14 is articulated in first end 18 at said housing 12 tops.Said locker also comprises the elastic metallic yarn 20 in the storage tank 17 that is placed in said card lid 14 and is slidingly connected to the snap close 21 of first end 15 of said card lid 14.Said snap close 21 have be used to collude the button said housing 12 tops with trips 22 said first end, 18 second opposed end 19.Second end 19 that said snap close 21 compresses said elastic metallic yarn 20 and makes said trip 22 break away from said housing 12 tops when second end 16 of said card lid 14 slides dorsad.Said elastic metallic yarn 20 is bent back and forth in same plane by an one metal wire and forms.Said elastic metallic yarn 20 lies against in the storage tank 17 of said card lid 14.
Because said elastic metallic yarn 20 is bent back and forth in same plane by an one metal wire and forms, moulding is simple, and in addition, said elastic metallic yarn 20 lies against in the storage tank 17 of said card lid 14, saves the space, makes snap close 21 device slimming and small sizes.Said storage tank 17 rectangular shapes.
20 compressions of said elastic metallic yarn place 17 li of storage tanks, and said elastic metallic yarn 20 is limited at 17 li four sides of storage tank, and when assembling, elastic metallic yarn 20 is packed in the storage tank 17 in advance, makes easy to assembly and easy.
Said snap close 21 comprises a mainboard 23, the block 24 that is extended towards said card lid 14 by said mainboard 23 and two slide blocks 25 that are arranged at said mainboard 23 relative both sides respectively.Said trip 22 is extended by second end 16 bending downwards away from said card lid 14 of said mainboard 23.Second end 19 at said housing 12 tops is provided with the draw-in groove 26 that the trip 22 that supplies said snap close 21 colludes button.Said slide block 25 is slidingly fastened on the said card lid 14.Said block 24 slides along with second end, 16 slips of the said dorsad card lid 14 of said slide block 25 and compresses said elastic metallic yarn 20.Mainboard 23 end faces of said snap close 21 are provided with the convenient some fins 27 that promote said snap close 21.
Said elastic metallic yarn 20 comprises two support divisions 28 that are arranged at opposite end and is connected at least two kinks 29 between the said support division 28.Wherein a support division 28 presses on the said snap close 21 and (specifically, presses on the block 24 of said snap close 21), and another support division 28 presses on the side wall surface 30 of said storage tank 17.In the present embodiment, the quantity of said kink 29 is two, makes said elastic metallic yarn 20 be perhaps " S " font of " Z " font, and at this moment, said two support divisions 28 extend dorsad.In other embodiments, the quantity of said kink 29 is three, makes said elastic metallic yarn 20 be " M " font, and at this moment, said two support divisions 28 extend in the same way.Can know that by that analogy when the quantity of said kink 29 was even number, said two support divisions 28 extended dorsad.When the quantity of said kink 29 is odd number, said two support divisions 28 extend in the same way.
Said slide block 25 comprises that the bottom surface by said mainboard 23 outwards protrudes out and be stuck in the fixture block 32 on the said card lid 14 to the respective side edge that the projection that extends below 31 reaches by said mainboard 23.Said projection 31 carries out chamfered and forms guiding face 33 with the junction of said fixture block 32.The top that said card covers 14 first ends 15 offers confession its first interior chute 34 of said block 24 slips and supplies said its second interior chute 35 of slide block 25 slips.Said second chute 35 comprises the projection groove 36 of ccontaining said projection 31 and the fixture block groove 37 of ccontaining said fixture block 32.Be formed with between the end face of said fixture block groove 36 and said card lid 14 and stop that said fixture block 32 breaks away from the stop part 38 of said fixture block groove 36.The said fixture block 32 of said guiding face 33 guiding slips over said stop part 38 and gets in the said fixture block groove 37.
During assembling, earlier said elastic metallic yarn 20 is lain against in the storage tank 17 of said card lid 14, elastic metallic yarn 20 is subject in the said storage tank 17.Then; Snap close 21 is stuck in downwards on the said card lid 14, and at this moment, elastic metallic yarn 20 is folded between said card lid 14 and the said snap close 21; The block 24 of said snap close 21 slides in first chute 34, and the slide block 25 of said snap close 21 slides and is stuck in said second chute 35.Then, second end 16 of said card lid 14 is articulated on the said housing 12.In use; Push said card lid 14 towards said housing 12; The fillet surface 43 of said trip 22 covers and slipped over said arc surface 42 at 14 o'clock pushing said card towards said housing 12; The block 24 of snap close 21 slides with respect to said card lid 14 with slide block 25 outwardly, and at this moment, said block 24 compresses the corresponding support division 28 of elastic metallic yarn 20 and makes elastic metallic yarn 20 be in compressive state.Under the elastic force effect of said elastic metallic yarn 20, said trip 22 is stuck in the said draw-in groove 26.At this moment, said snap close 21 devices are in locking state.When needs are opened said snap close 21 devices, only need promote said snap close 21 outwardly, with trip 22 by breaking away from the said draw-in groove 26.No matter be locker in the locking process or in the opening process, the rotating shaft 44 of second end 16 of said card lid 14 is rotated in axis hole 45.Therefore, snap close 21 structures provided by the invention are easy to use, and technology is simple.
Utilize elastic metallic yarn 20 for snap close 21 elastic force to be provided, technology is simple, dependable performance.Elastic metallic yarn 20 volumes are little, and it is little to take up room, and put elastic metallic yarn 20 into storage tank 17 earlier during assembling, can avoid elastic metallic yarn 20 unrest when assembling to jump and lose.
The specific embodiment of the above is a preferred embodiments of the present invention, is not to limit practical implementation scope of the present invention with this, and scope of the present invention comprises and is not limited to this specific embodiment.All shapes according to the present invention, the equivalence variation that structure is done all comprise in protection scope of the present invention.
