Description

A kind of CD storage table structure

The utility model relates to a kind of CD storage table structure.

Existing video disc player can only be deposited three video discs at most simultaneously, and can't be used in combination, and is difficult to satisfy the needs that DVD multidisc is levied access and broadcast.

The purpose of this utility model is exactly to provide a kind of CD storage table structure that can deposit many video discs simultaneously and can be used in combination for people.

Main body of the present utility model is a circular base material, there is the open circles of a gear-like at this circle base material middle part, the outer ring-type convex tendon that is with one in this open circles, the two ends up and down of this convex tendon all exceed substrate surface, on this convex tendon, be evenly distributed with the circular hole of six up/down perforations, also be evenly distributed with five notched circular grooves and a circular hole in the periphery of this convex tendon, the center of circle of circular groove and circular hole is on same circumference.

The utility model monomer can be deposited 5 standard video discs simultaneously, a plurality of the utility model combination of monomers together, be aided with other parts again, can constitute the laser disc holding structure that to deposit hundreds of video discs simultaneously, and can automatically carry out selectable access, thereby reach the purpose of saving artificial and machine robotization to the video disc that leaves on all the utility model monomers.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a partial schematic diagram of the present utility model.

Fig. 3 is the cut-open view of Fig. 2.

Referring to each accompanying drawing, main body of the present utility model is the positive circular shuttering base material of a slice diameter 380MM, thick 1MM, there is the open circles (hereinafter to be referred as the gear circle) of a gear-like by inwardly hobbing formation at its positive center, the diameter of a circle that gear circle pleodont point surrounds is 90MM, the diameter of a circle that empty gear point surrounds then is 98MM, the gear degree of depth is that tooth length is 4MM, the i.e. distance of a, b point-to-point transmission among Fig. 1.The gear shape sinusoidal waveform that is near the mark.Gear thickness after the compacting is 3MM (base material thickness is that L7 is 1MM relatively, then its compacting knuckle limit 2MM).The gear seam bottom of this gear circle is that " base position gear lacks " named at the c place among Fig. 1, and it stitches more profound than other gears, and specifically data are tooth depth 6MM.This tooth is scarce to be shaped as near equilateral triangle, and it is wide that its gap width is not less than other notch gears, and its effect is can be in same reference position when the overlapping placement of a plurality of the utility model monomers.

At the outer ring-type convex tendon that is with one of gear circle, it all exceeds the circular shuttering substrate surface in two ends up and down, and wherein the lower end is long than the upper end.This convex tendon is to form like this: the annulus that laminates the thick 1MM of a circle at the upper surface of base material, lower surface laminates the annulus with the thick 3MM of material, this annulus upper space after laminating is 5MM to the distance of lowest surface, and this also is the full-size of the utility model thickness.The interior circle footpath of convex tendon is 105MM, and outer circle diameter is 125MM.Ring width is that L6 is 10MM.It is gone up most, lowest surface all is the plane, and they are surface in contacts of adjacent two monomers when a plurality of the utility model monomers are stacked together.The interior circle of this convex tendon is L5 to the pleodont point distance of gear.Its value is (125-20-90)/2=7.5MM (125 refer to the convex tendon outside diameter in the formula, and 20 refer to that the twice convex tendon is wide, and 90 refer to pleodont point place circular diameter).On aforementioned convex tendon, be evenly distributed with 6 circular holes that connect the convex tendon upper and lower surface, its " deciding dish position unthreaded hole " by name, aperture 8MM.The effect of this circular hole is when a plurality of the utility model monomers stack, and can make luminous energy successfully be delivered to the other end from an end, is convenient to the utility model and photo measure device and gear train and cooperatively interacts, and then reach the purpose of automatic access video disc.

The center of circle of five notched circular grooves and a vacancy circular hole is evenly distributed on the periphery of convex tendon on same circumference, they and 6 " deciding dish position unthreaded hole " are corresponding one by one.The name of vacancy circular hole is called " cross dish hole ", i.e. the aperture passage that passes through of video disc.The name of other five circular grooves is called " putting the dish position ", is used to place video disc." cross dish hole " is an empty circular hole that hobs out at the edge of circular shuttering base material, also has the breach of a wide 70MM in the outermost edge of base material, and this Circularhole diameter is 125MM.For fear of the surface deformation of product, a kind of knuckle limit technology is taked at the edge of " crossing the dish hole ", promptly extrudes an angle of 90 degrees limit of thick 3MM in the marginarium of " crossing the dish hole " inside (descending).See " putting the dish position " again, each " puts the dish position " outside opening all is on the base material cut-out.Its A/F is that L1 is 55MM, notch depth 85MM.Five identical " putting the dish position " districts are notched cascaded surface (as shown in Figure 3).Its outermost one circle diameter of a circle is that L4 is similarly 125MM, and several circles district is inside (descending) gradually low several terraces in it, i.e. three concentric circless among Fig. 2, and it is the table plane projection from the top down of three differing heights.Wherein the A point refers to the outermost edge of convex tendon, and the B point refers to put the outermost one circle circle of dish position, and some D is second road circle, and some E is the 3rd a road circle.Point A, B, D, E illustratedly depart from just conveniently for mark originally on a line of convex tendon and this junction of " putting the dish position ", we can say that also the every bit of mark can be represented the everywhere that its place is round.The outside that circle of Fig. 2 is promptly put B place circle is a base plane, i.e. base material table plane.The first road circle is " sliding dish slope district ", i.e. zone between BD to second road circle district.This is a slope, and effect is to allow certain operate miss when placing video disc.Its spacing is 2MM, and difference in height is 1.5MM.The second road circle to the, three roads circle district is " putting the dish stepped region ", is used to place video disc, i.e. the annulus that surrounds of zone between DE, and its external diameter is that L3 is 121MM, internal diameter is that L2 is 117MM, ring width 2MM.The 3rd road circle is interior to be the base district to relief area, promptly puts the plane domain of E with interior some F place, and it is the low again 0.5MM in DE plane than putting the dish plane, is called " base plane ", and its concrete effect is the damage of avoiding CD-RW discsCD-RW information-recording district.

Fringe region of the present utility model is all taked knuckle limit technology basically, and this is for preventing the plane deformation of product.Ragged edge one circle edge and a circle edge (heavy line as shown in Fig. 1) in " crossing the dish hole " district and the edge of gear circle as product have all adopted an angle of 90 degrees limit with base material inside (descending) crimping certain size in the marginarium of thick 1MM.With this product is example, and flanging thickness all is 3MM.But in " putting the dish position " zone, consider the manufacturing dimension of its actual configuration and product, this a part of gap edge does not carry out the knuckle limit to be handled.
