Appended drawings is a composition structural representation of the present invention.The present invention is integrally molded in the matrix or the pallet of the light disk packing box on it, omits and does not draw.
A kind of CD holding mechanism of embodiment
This CD holding mechanism, be integrally molded on the matrix or pallet of light disk packing box, comprise that diameter is slightly less than the oblate tubular button shape body in cd centre aperture, be connected with the oblate tube bottom of button shape body with the top and round table surface that the bottom is connected with the matrix or the pallet of light disk packing box, also axially towards tilting, the external diameter of the not record of its bottom diameter and CD and the annular region of canned data slightly together from the bottom radial inward for round table surface.
Described button shape body is divided into 4 by a cruciform notch 2 and is spaced from each other, equal and opposite in direction, the right angle that shape is identical fan-shaped button shape daughter 3, the outer midpoint of each right angle fan-shaped button shape daughter 3, be provided with the blocked block 4 of a radially outwardly projecting, the upper surface of this blocked block 4 is arc surfaces, the lower surface is a plane, it highly is thickness poor of the height of the oblate tube of button shape body 1 and CD, on, the intersecting lens of lower surface is that the round button face with button shape body is a concentrically ringed circular arc line, the slightly larger in diameter of this circular arc line is in the cd centre aperture, and promptly the radial dimension of blocked block 4 is slightly larger than the cd centre aperture.
On round table surface 5, be provided with 4 ports of cruciform notch 2 and be communicated with respectively to constitute 4 inverted U-shaped notches 6 of the shape of falling Y notch, promptly on the oblate tube 1 of round table surface 5 and button shape body, be provided with the shape of the falling Y notch that is communicated with, on round table surface 5, constitute equally distributed 4 inverted U-shaped flexure strips 8 being distinguished semi-surroundings by 4 inverted U-shaped notches 6.
Under relative with the blocked block 4 of described 4 radially outwardly projectings on the round table surface 5, locate, also correspondingly be respectively equipped with 4 rectangular through holes, and under relative with the blocked block 6 of described 4 radially outwardly projectings on the oblate tube 1 of button shape body, locate, also be respectively equipped with above-mentioned 4 rectangular through holes and be communicated with respectively, promptly on round table surface 5 and button shape body oblate 1, be provided with the convex-shaped hole 7 that is communicated with to constitute 4 vertical bar shaped through holes of convex-shaped hole 7.
The shape of falling Y notch and convex-shaped hole 7 are set, can improve the oblate tubular button shape body of this card holding structure and the flexibility and the elasticity of round table surface 5, to improve its unloading convenience significantly to CD.
Oblate 1 inwall 4 vertical bar shaped through hole both sides, be respectively equipped with upright reinforcement, the back side at the right angle of 4 right angle fan-shaped button shape daughters 3 fan button face, be respectively equipped with the L shaped reinforcement that two ends are connected with above-mentioned upright reinforcement top, the back side of the round table surface 5 between inverted U-shaped notch 6 and vertical bar shaped through hole also is respectively equipped with the reinforcement that is connected with above-mentioned upright reinforcement bottom.These reinforcements can improve the physical strength of the elastic sheet structure of this card holding structure, strengthen the endogenous capacity that this card holding structure prevents the external impact force influence.
CD is lain on the oblate tubular button shape body, cd center hole is along contacting with the upper end arc surface of blocked block 4, with finger CD is applied certain pressure, the cruciform notch 2 of button shape body shrinks, blocked block 4 passes cd center hole, be enclosed within until cd center hole on the oblate tube 1 of oblate tubular button shape body, CD is placed reposefully, promptly is positioned at the oblate tube of the 5 button shape bodies that are connected 1 bottom with round platform.The external diameter of the not record of the bottom diameter of round table surface 5 and CD and the annular region of canned data slightly together, the annular region that has write down with canned data is built on stilts state, can not bump or rub with the matrix or the pallet of light disk packing box, can avoid the wearing and tearing that may cause the CD card effectively, the CD card has write down with canned data and can not be damaged.And after CD is placed reposefully, finger promptly is cancelled the CD applied pressure, the cruciform notch 2 of button shape body stretches and resets, blocked block 4 also is reset to original state with flexible form, the radial dimension of blocked block 4 is slightly larger than the cd centre aperture, blocked block 4 can be rigidly held in CD below it, the upper surface of CD can be close to the lower surface that blocked block 4 is planes, can not be moved at the matrix or the pallet of light disk packing box, upset or when being subjected to vibrating, the catch mechanism of dissociating, because the diameter of oblate tubular button shape body is slightly less than the cd centre aperture, the CD that is held has just limited axial moving, and it still can freely rotate around oblate tubular button shape body.Each assembly of card holding structure all is reset to original state.
As long as with single forefinger oblate tubular button shape body is exerted pressure a little, the cruciform notch 2 of button shape body shrinks, and blocked block 4 bounces back to cd center hole along the place, discharges holding CD.Be provided with 4 ports of cruciform notch 2 and be communicated with round table surface 5 respectively with 4 inverted U-shaped notches 6 that constitute the shape of falling Y notch, has enough flexibilities and elasticity, at single finger to oblate tubular button shape body a little under the applied pressure effect, distinguished 4 inverted U-shaped flexure strips 8 of semi-surroundings on the round table surface 5 by 4 inverted U-shaped notches 6, can be with CD lifting a little, make it skid off blocked block 4, single forefinger is to oblate tubular button shape body applied pressure a little, be cancelled immediately, thumb and the middle finger or the third finger with the same hand, clamp the outer of CD, unloading CD easily, each assembly of card holding structure all is reset to original state.
Above content is in conjunction with an embodiment, to the detailed description that the present invention makes, can not assert that structural design of the present invention is confined to these explanations.The scope of the present invention is to be determined by claims of being submitted to.
