The utility model content

The purpose of this utility model is to provide a kind of jewel case structural improvement, it is higher to have solved jewel case cost of manufacture commonly used, the size that can't adjust jewel case is with the increase and decrease in response to the CD-RW discsCD-RW peanut, desire to hold the CD-RW discsCD-RW of different size number, center pillar and shell all must be made again, and the time of increase processing procedure and cost are than problems such as height.

The technical solution of the utility model is: include a loam cake, it is provided with a hole slot toward interior extension, and this hole slot is provided with the spiral shell bud of plural number, and the set screw thread of this spiral shell bud and center pillar cooperatively interacts; One bottom, this bottom is provided with one and wears groove, and its diameter is corresponding to center pillar; One center pillar, one side are provided with the screw thread of plural number, cooperatively interact with spiral shell bud in the set hole slot of loam cake, and this center pillar opposite side is provided with plural elasticity coupler body, and this center pillar is worn the perforation of the penetrating bottom coupler body by plural number and is fastened in bottom; Can be provided with the center pillar of different length of thread by replacing, holding the CD-RW discsCD-RW of different numbers, and not need other die sinking to make the loam cake and the bottoms of different sizes, can save the cost of making; The screw thread of center pillar can be whole segmentation design, also can be partly screw thread design; Loam cake can be set up an anti-joyride device, and this anti-joyride device is arranged on the engagement section of center pillar and loam cake, and this anti-joyride device is the lid of a projection and the block end of complete coating center pillar and loam cake, to prevent to encroach on the opening behavior of businessman's rights and interests; This anti-joyride device comprises a lid and a trip, needs by the rotation lid trip to be broken, and lid is broken away from behind trip, can rotate center pillar and loam cake, to take out built-in CD-RW discsCD-RW; The opposite side of center pillar is provided with the elasticity kayser that plural number protrudes, and center pillar passes the set groove of wearing of bottom and firmly is sticked in bottom by this elasticity kayser; Loam cake is provided with a protruding dish portion, and with the corresponding engaging of recessed dish portion of bottom, this design can make that laser disc is simple and easy to be piled up, and can save the storage area; Loam cake can be set up a mobile division to be convenient for carrying.

Advantage of the present utility model is: need not make shell, escapable cost; Can make the screw thread that is sticked in the set differing heights of center pillar by the rotation loam cake, to adjust the jewel case capacity; The jewel case of different size capacity does not need to make in addition loam cake and bottom, only need change the center pillar that is carved with the different length screw thread, can save the time of processing procedure and spend less, practical.
