Lock snap structure of slide rail

摘要

A lock snap structure of a slide rail includes an inner rail provided with two adjacent locking plates and a locking groove between the two locking plates. Each locking plate is formed with a slope. An outer rail mounted on the inner rail is provided with a retaining plate which has a guide block which may move along the slope of the locking plates to enter the locking groove. A drawing plate mounted between the inner rail and the outer rail has a first end that may be pulled and a second end pulled by an elastic member. The drawing plate has a slot hole provided with a guide plate which has an oblique shoulder that may press the guide block when the drawing plate is moved, so that the guide block may detach from the locking groove between the locking plates.
