Sliding rail structure

A sliding rail structure, comprising:

• a fixed rail;
• a first sliding unit for sliding along the fixed rail;
• and
• a second sliding unit for sliding along the first sliding unit,
• wherein a blocking portion is disposed on a surface of the fixed rail and positioned near an end thereof, and two raised rails, which are symmetrical and parallel, are formed by stamping on a surface of the fixed rail and positioned near another end thereof, with an actuation slideway formed between the two raised rails,
• wherein a front stopper and a rear stopper are protrudingly disposed at two ends of the actuation slideway respectively, and the actuation slideway receives an actuation element capable of sliding and undergoing displacement, with the actuation element confined to space defined between the front and rear stoppers,
• wherein a tip portion comprising two oblique surfaces is disposed at an end of the actuation element and faces the front stopper,
• wherein an outward pushing portion and an inward pushing portion are protrudingly disposed on a surface of the actuation element, and a plug-in hole facing the actuation slideway is disposed on each of two sides of the fixed rail and configured to provide for the insertion of a lock piece,
• wherein each of the two raised rails has a hollow-core segment aligned with and configured to be in communication with the two plug-in holes such that the lock pieces pass through the plug-in holes and then enter the hollow-core segments,
• wherein a guiding oblique end is formed at each of two ends of the lock piece and configured to come into contact with the tip portion of the actuation element,
• wherein a groove having an actuation spring plate is recessed into a bottom surface of the first sliding unit along a forming direction and centrally provided with an inward-pushing bump and a through-hole, the inward-pushing bump interacting correspondingly with the inward pushing portion of the actuation element,
• wherein the actuation spring plate has a raised oblique surface and faces the through-hole, and an end of the raised oblique surface bends to extend downward to form a guiding end, the guiding end centrally denting to form an outward-pushing top portion, and the outward-pushing top portion interacting correspondingly with the outward pushing portion of the actuation element.
