Abstract

The invention discloses an explosion rupture disk device of a CD player. The front end of a machine case is provided with an opening, and the front end edge of the upper side of the opening is downward bent to form a row of baffles to stop part of the opening. A tray can be arranged inside the machine case in an in-out mode; the tray is concavely provided with a disk sheet bearing groove; and theupper surface in front of the bearing groove is convexly provided with at least one retaining wall. After the tray enters the machine case and is positioned, the position of the retaining wall protruded out of the tray is staggered with the position of the downward stretching of the baffles so as to reduce vertical intervals between the retaining wall and the baffles.

Description

technical field [0001] The invention relates to an optical disc drive, in particular to an explosion-proof plate device for safely protecting a broken optical disc from flying out of the optical disc drive and causing damage when the optical disc drive is rotating. Background technique [0002] Optical discs are molded from plastic materials, which are often deformed due to manufacturing defects, material unevenness, deterioration or temperature. When the optical disc drive rotates the optical disc at a high speed to read and write data, the optical disc is prone to violent vibrations, causing the optical disc to break and scatter, endangering the safety of users. [0003] In order to prevent damage caused by fragments, such as figure 1 As shown, it is the optical disk drive 1 of the background technology of US Patent Publication No. 2004081056. 2. Description of the Related Art An optical disk drive 1 uses an explosion-proof plate device to bend the front edge of the casi...
