Drawer slide assembly

A drawer slide assembly, comprising:

• an upper slide;
• an inner slide;
• at least two upper sliding guides being provided on a top and a bottom with a plurality of first sliding bearings, and on a lateral wall with a plurality of second sliding bearings, such that the first sliding bearings on the top of the upper sliding guides bear against an upper inner surface of the upper slide and an upper outer surface of the inner slide, the first sliding bearings on the bottom of the upper sliding guides bear against a lower inner surface of the upper slide and an upper inner surface of the inner slide, and the second sliding bearings bear against a lateral inner surface of the upper slide and a lateral upper outer surface of the inner slide, causing the upper slide and the inner slide to mutually slidably assemble to each other;
• a lower slide having a buffer unit fixedly located thereabove;
• at least two lower sliding guides being provided on a top and a bottom with a plurality of third sliding bearings, such that the third sliding bearings on the top of the lower sliding guides bear against an upper inner surface of the lower slide and a lower inner surface of the inner slide, and the third sliding bearings on the bottom of the lower sliding guides bear against a lower inner surface of the lower slide and an lower outer surface of the inner slide, causing the lower slide and the inner slide to mutually slidably assemble to each other;
• and
• a mounting plate for holding the mutually assembled upper, lower, and inner slides to a predetermined position.

A drawer slide assembly, comprising:

• an upper slide being provided at one longitudinal side with an actuator;
• an inner slide;
• at least two upper sliding guides for causing the upper slide and the inner slide to mutually slidably assemble to each other;
• a buffer unit being located in the inner slide and including a base and a buffer element;
• the buffer element having a piston rod provided at an outer end thereof, and the base being formed with a slide slot, at a terminal of which a retaining slot is provided;
• a linking member being mounted in the slide slot to connect to the piston rod via a link rod, and being controlled by the actuator on the upper slide to move into and out of the retaining slot on the base;
• and an elastic element being provided in the base with an end fixed to a point in the base and the other end connected to the linking member;
• and
• a mounting plate for holding the mutually assembled upper and inner slides to a predetermined position.
