Interlock mechanism for drawer slide rail
First Claim
1. An interlock mechanism for drawer slide rail, installed in at least two vertically arranged drawers, each of which outer wall and an object'"'"'s inner wall are provided with a drawer slide rail, respectively, formed by an inner and outer slide rails, comprising:
- a seat housing connectingly provided in the end of an outer slide rail, wherein the center of the seat housing extends outwardly to form a belt-like protrusion which is provided with a arc limit groove in its middle;
an actuator comprising a cover plate slidingly connected in front of the seat housing and a twisted spline provided on the inner side of the cover plate corresponding to the limit groove;
a rotating part axially connected to the back of the seat housing, wherein the inner side of the rotating part axially extends to form a push rod whose one end is protrudingly provided with a turn tenon which passes through the limit groove and is fittingly connected with the spline;
at least a follower slidingly provided on the back of the seat housing and adjacently connected to the recessed joint provided on the rotating part; and
a hook bolt connectingly provided at the end of a slide rail;
when the actuator moves into position along the inner slide rail, a spline will drive a turning tenon of the rotating part to protrude over the limit groove of the seat housing, and thus the motion of the turning tenon changes from linear movement to rotating movement so as to turn the rotating part into rotating movement, and in turn drive the push rod'"'"'s long side to push the joint of the follower to move longitudinally.

Abstract
The present invention discloses an interlock mechanism for drawer slide rail, which is installed in at least two vertically arranged drawers, each of which outer wall and an object'"'"'s inner wall are provided with a drawer slide rail, respectively, formed by an inner and outer slide rails. The interlock mechanism comprises a seat housing, an actuator, a rotating part, at least a follower, and a hook bolt. When the actuator moves into position along the inner slide rail, a spline will drive a turning tenon of the rotating part to protrude over the limit groove of the seat housing, and thus the motion of the turning tenon changes from linear movement to rotating movement so as to turn the rotating part into rotating movement, and in turn drive the push rod'"'"'s long side to push the joint of the follower to move longitudinally. Furthermore, the present invention further comprises an automatic retracting mechanism, in which the hook bolt on the end of the inner slide rail can be retracted automatically with respect to the seat housing on the end of the outer slide rail.
