Slide rail with internal contraction movable rail
Technical Field
The invention relates to a sliding rail, in particular to a sliding rail with an inner-contracting movable rail.
Background
Traditional slide rail is because the difference of individual factors such as frictional force, effort, both sides slide rail can not synchronous work, and this bearing force that just leads to both sides slide rail produces unbalanced phenomenon, and long-time atress inequality work leads to both sides slide rail to receive the wearing and tearing of different degrees, and because the degree of wear of both sides slide rail is different, leads to both sides slide rail difference nature more and more come, makes the switch smoothness nature of two slide rails reduce, influences the use embodiment of product to the wearing and tearing of slide rail accelerate, make its life shorten. In addition, the existing slide rails are not provided with a closed locking structure, even if the slide rails are provided with the closed locking structure, the locking and unlocking of the slide rails are realized disorderly, and the inner rails are not retracted, so that the length of the outer rails is limited, and when the inner rails and/or the middle rails are opened and pulled out, the supporting force of the outer rails on the inner rails and the middle rails is limited, so that the structure of the slide rails in an opening state is unstable, and the deformation of the inner rails and the middle rails is easily caused, thereby influencing the use embodiment and the service life. Therefore, the conventional slide rail still needs to be further improved.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, provides a sliding rail with an inner telescopic movable rail, wherein a middle rail can move synchronously, an inner rail can be quickly assembled and disassembled, and the sequential locking and unlocking effects of the sliding rail are realized through the structure that an outer rail locks and unlocks the middle rail and the middle rail locks and unlocks the inner rail.
The purpose of the invention is realized as follows: a sliding rail with an inner retractable movable rail comprises an outer rail, a middle rail and an inner rail, wherein the middle rail moves on the outer rail, and the inner rail moves on the middle rail; the method is characterized in that: the middle rail is provided with an oblique buckle in a resetting rotating mode, the outer rail is provided with a stop boss, the oblique buckle is provided with a stop block, and the stop boss falls on a moving track of the stop block to prevent the middle rail from moving relative to the outer rail; when the inner rail moves to a certain position, the moving track of the action stop block deviates from the stop boss, so that the middle rail can be unlocked and moved relative to the outer rail; the inner rail is elastically reset and rotates with a slide rail locking plate with a slide rail bayonet, and the middle rail is provided with a locking block; in the closed state, the locking block is buckled in the slide rail clamping opening; when the slide rail is unlocked, the slide rail bayonet is separated from the locking block under the action of the slide rail locking plate so as to unlock the slide rail.
