Abstract
The utility model relates to a material-saving CD, which is provided with a blank annular plastic plate without data record in a data reading-writing zone in a circular ring shape of the existing CD, wherein the internal and the external diameters of the plastic plate are respectively 15 mm and 35 mm. Materials in the part can be replaced by a circular-hole plastic circular ring and a bar-shaped plastic connecting plate of the utility model; by adopting the proposal, materials of each CD can be saved by 5.3 percent under the condition that the normal use of a CD can not be affected so as to play the important functions of energy conservation and the product-quantity improvement of CD manufacture industry.
Description
One, technical field
The utility model relates to a kind of CD, particularly relates to a kind of material-saving CD of saving material.
Two, background technology
In the annular data carving district of existing CD, there is external diameter one in to be respectively the blank annular plastics sheet of the no datat record of 15mm and 35mm, its effect: 1. make the optical disk reading taking equipment drive whole CD rotation by shaft hole; 2. forming diameter is the shaft hole of 15mm.And will satisfy these two functions is not to leave no choice but realize with such annular plastics sheet, and this way of existing CD is a kind of waste in fact.
Three, utility model content
The utility model provides a kind of and can save 5.3% material for every CD for solving the deficiencies in the prior art, does not influence the material-saving CD that CD uses simultaneously again fully.
The scheme that solves the utility model technical matters is: save the blank annular plastics sheet that no datat that interior external diameter in conventional optical disc shaft hole and the annular data carving district around its is respectively 15mm and 36mm writes down.Diameter be 15mm shaft hole by interior external diameter be respectively 15mm and 23mm the circular hole plastic circle ring form circular hole plastic circle ring and annular data carving district concentric.Between circular hole plastic circle ring and data carving district, be 120 degree plane distribution again with three, and separately center line all meet at the CD center of circle the bar plastic brace connect, bar plastic brace width is 6mm.With the angle of bar plastic brace and circular hole plastic circle ring, junction, data carving district is that the arc angling of 2mm is handled as radius all, the stress that produces in this position when resisting the CD rotation.Circular hole plastic circle ring, bar plastic brace and data carving district are a jointless integral body, and thickness is 1mm.
Adopt such scheme can save 5.3% material for every CD, the material that 19 CDs of promptly every production are saved can be produced a CD again.This reduces cost to the CD manufacturing industry and improves output and all can play an important role.
Four, description of drawings
Fig. 1 is the structural drawing of material-saving CD;
Among the figure: 1 is the data carving district, and 2 is the circular hole plastic circle ring, and 3 is the bar plastic brace.
Claims (1)
1, a kind of material-saving CD, it comprises the data carving district, circular hole plastic circle ring and bar plastic brace, it is characterized in that: the shaft hole diameter of CD is 15mm, by interior external diameter be respectively 15mm and 23mm the circular hole plastic circle ring form, circular hole plastic circle ring and annular data carving district concentric, be 120 degree plane distribution by three between circular hole plastic circle ring and the data carving district, and separately center line all meet at the CD center of circle the bar plastic brace connect, bar plastic brace width is 6mm, bar plastic brace and circular hole plastic circle ring, the angle of junction, data carving district all is the arc angling processing of 2mm as radius, the circular hole plastic circle ring, bar plastic brace and data carving district are a jointless integral body, and thickness is 1mm.
