Abstract

A drawer slide module structure is composed of an inner slide and an outer slide. The inner slide includes a latch body installed therein, and an indent and an end portion disposed at innermost positions on both sides of the inner slide. The outer slide includes a resuming base disposed at a position corresponding to the latch body of the inner slide, and a locking base installed at a rear side of the resuming base. With the design of a driving member in the resuming base swung with a link member as an axle point, the driving member and the link member will not be damaged, when the drawer is pushed back; if one of the drawers in the whole cabinet is pulled open, the locking base will latch the inner slides of other drawers, so that other drawers will not fall out freely.

Claims

1. A drawer slide module structure, with its slide module comprised of an inner slide and an outer slide, characterized in that:

said inner slide, installing a latch body, and having an indent and an end portion disposed at innermost positions on both sides in said inner slide;

said outer slide, having a resuming base disposed at a position corresponding to said latch body of said inner slide, a locking base disposed on a rear side of said resuming base, a section of rectangular protruding top disposed in an internal concave space of said resuming base, an indent disposed at a rear side of said rectangular protruding top for receiving a link member, a swayable resilient plate disposed above said indent, a pivotal axle disposed at the front of said link member and hooked by a curved hook at the lower back side of said driving member, a hook disposed at the front of said curved hook which is latched with a spring module inside an internal concave space of the resuming base;

an inclined plane and a groove disposed above another driving member;

a cross groove disposed on said locking base;

a sunken groove disposed in a vertical groove of said cross groove for separately installing two sets of retarding members and springs;

an inclined plane disposed on a side of a transversal groove of said cross groove, for placing a bent and curved long spring and both upper and lower ends of said long spring pressing against a lateral surface of said retarding member;

a through groove disposed on another side of said transversal groove, for passing a top plate, and a rear end of said top plate pressing against the bent and curved position of said long spring, and a front end of said top plate being propped and restricted by a link member on said resuming base;

such that after a plurality of slide modules are installed to a cabinet, said link member is swung with respect to said link member in said resuming base by an axle point, so as to make sure that when the drawer is pushed back, said link members will not be damaged, and if one of said drawers of said cabinet is pulled open, said retarding member of said locking base retards and stops said retarding members coupled to other locking bases, and thereby other drawers will not fall out freely.
