Elastic sheet for machine core disc-pressing module

Abstract

The invention relates to the field of a CD-ROM (Compact Disc Read-Only Memory) driver, and particularly discloses an elastic sheet for a machine core disc-pressing module. The elastic sheet comprises a sheet made of plastic materials; the sheet comprises a bottom wall; a rear mounting part and a front disc-pressing part are arranged on the bottom wall; left and right sides of the rear mounting part are respectively bent upward vertically, thereby forming left and right side bent edges; and the left and right side bent edges are respectively bent outward, thereby forming left and right transversal bent edges. The elastic sheet for the machine core disc-pressing module provided by the invention is made of plastic sheet materials, and friction of a matched plastic gland lug is plastic-plastic friction, thereby being difficult to abrade the plastic gland lug and realizing higher disc-reading reliability.

Description

technical field [0001] The invention relates to the field of optical disc drives, in particular to a shrapnel for a disc pressing module of a core. Background technique [0002] see also figure 1 , figure 2 , which means a shrapnel of a traditional suction-type disc pressing module. Its purpose is that when the disc rotates at high speed and reads the disc, the small movement parts will not be under great force. Does not slip. Such as figure 1 As shown, the shrapnel of the pressure disc module of the transmission and suction movement generally adopts hardware components with a relatively complex structure to achieve its reliability, but the processing technology of the components is relatively complicated, and the cost of the components is relatively high. In addition, due to the long time of reading the disc, the hardware shrapnel will rub against the bumps of the plastic gland, which will wear the bumps of the plastic gland, thus leaving a hidden danger of bad disc re...

AI Technical Summary

Problems solved by technology

like figure 1 As shown, the shrapnel of the pressure disc module of the transmission and suction movement generally adopts hardware components with a relatively complex structure to achieve its reliability, but the processing technology of the components is relatively complicated, and the cost of the components is relatively high

In addition, due to the long time of disc reading, the hardware shrapnel will rub against the bumps of the plastic cover, which will wear the bumps of the plastic cover, thus leaving a hidden danger of bad disc reading.
