Drawer locking apparatus of a cabinet

A drawer locking apparatus of a cabinet, comprising:

• a cabinet body which is a solid body composed of five rectangular panels defining an internal space and a vertical open face, at least one drawer being back and forth slidably disposed in the open face, the drawer being composed of five rectangular panels defining an opening facing upward;
• a base seat mounted on inner side of rear panel of the cabinet body corresponding to rear side of the drawer;
• a slide section vertically slidably fitted in the base seat and slidable between a first position and a second position;
• a first engaging section disposed on the drawer;
• a second engaging section, one end of the second engaging section being disposed on the slide section corresponding to the first engaging section, the other end of the second engaging section having a hook plate with a guide slope, whereby when the slide section is positioned in the first position, the hook plate will not hinder the first engaging section from passing through the hook plate, whereby the drawer can be freely back and forth slid, when the slide section is positioned in the second position, the hook plate being engaged with the first engaging section, whereby the drawer cannot be drawn out of the cabinet body;
• and
• a dogging device including a force application section, a transmission section, a first coupling section and a second coupling section, the transmission section being disposed between the slide section and the force application section, the force application section serving to drive the transmission section to reciprocally move, the first coupling section being disposed on the transmission section, the second coupling section being disposed on the slide section for coupling with the first coupling section, the transmission section serving to drive the slide section to slide between the first and second positions, whereby when the slide section is positioned in the second position, the first engaging section can inward push the hook plate to drive the slide section to move to the first position and the first engaging section can pass over the hook plate, then the slide section being restored to the second position.
