Description

Positioning structure of slide rail release part

technical field

The invention relates to a positioning structure of a sliding rail release part, in particular, after the release part of the slide rail is operated to leave the original position, the release part has a temporary positioning function without continuously exerting force on the release part by hand design.

Background technique

For the general slide rail design, the one with stronger functionality has a type that can prevent the movable rail body from shrinking easily and slide into the fixed rail body after the movable rail body is pulled out, that is, the movable rail body is locked on the fixed rail body. Fix the rail body to prevent the retraction of the movable rail body in the stretched state, and this kind of positioning function of "preventing shrinkage" can be divided into two modes: "stable locking" and "elastic temporary positioning". "Locking" needs to cooperate with the release part of unlocking, so that the movable rail body can be pushed into the fixed rail body after unlocking; as for "elastic temporary positioning", the positioning can be automatically released by a certain thrust applied to the movable rail body function, to forcefully push the movable rail body; in addition, in order to prevent the movable rail body from being completely detached from the fixed rail when the movable rail body is pulled out from the fixed rail, a locking structure of "preventing disengagement" can also be provided. In addition, the movable rail body The rail body can also be set to be detachable, and the locking structure of "preventing disengagement" will also be designed with a release part for unlocking.

Drawer objects that generally use slide rails usually use a set of slide rails, that is, two slide rails are installed on the left and right sides of the drawer object, and when each slide rail has a "prevention When the mechanism of "retracting in" or "preventing disengagement" is operated, the operator can only operate the release parts of the left and right slide rails with both hands at the same time and continue to apply force to the release parts in order to operate the release parts. Push or pull the movable rail body together.
