Coupler mechanism

Abstract

A hook and lock structure includes a plate, hook, electric-magnetic valve, interlock device, the first moving arm and locking pin. On the hook an extruded column is capable of rotating to fix to the plate. The electric-magnetic valve is installed on the plate and is of moving block. The interlock device is linked to the moving block and capable of rotating to fix to the plate and push the hook. The first moving arm is capable of rotating to fix to the plate to move interlock device. On the first moving arm an extruded rib leans against the extruded column to push the hook. The locking pin locks with the hook.

Description

technical field [0001] The present invention relates to a hook mechanism, in particular to a hook mechanism for optical drives. Background technique [0002] With the advancement of technology, CD-ROM drives are gradually popularized and widely used in personal computers. However, in recent years, thin CD-ROM drives have been developed, which can be used together with notebook computers, allowing users to conveniently use the slim CD-ROM drive. Read CD. And the power source of the withdrawing mechanism of the tray of the general thin CD-ROM is to utilize the so-called solenoid valve, and the solenoid valve of this form is a normally closed type. Please refer to FIG. 1 to FIG. 5 , which are schematic diagrams of the hook mechanism and film feeding and film ejection of the existing middle tray. Referring to FIG. 1 and FIG. 2 , the existing hook mechanism includes a tray 11 , a hook 12 , a solenoid valve 13 , a linkage device 14 , a first swing arm 15 and a pin 16 . Wherein,...
