<p>The present invention provides a locking device of a portable laser video disc machine, especially provides a structure member combination of the laser video disc machine, which includes a pivot pivoted at the upside of the front end of the player and the underside of the front end of the display, magnets fixed in the underside of the front end of the display and gag bits fixed in the upside of the front end of the player and corresponding to the magnets, when the player and the display overlaps, the magnets and the gag bits keep close to each other. A non-clearance locking state is kept by the attraction of the magnets and the gag bits, which prevents the display from vibrating with a tiny extent in a high frequency around the pivot corresponding to the player due to the bumps in transporting. Preferably, the combinations of two magnets, a fixed gag bit and a movable gag bit are used in the two sides of the front end between the player and the display respectively, and cushion pads are set between the player and the display. The locking device can be opened easily, closed reliably, and is resistant to rampant bumps. This invention can protect the liquid crystal display effectively.</p> |
