Abstract

The invention provides a slide rail positioning device including an outer rail, a middle rail combined to the outer rail in a sliding manner and an inner rail combined to the middle rail in a sliding manner. The outer rail is provided with a stop block. The middle rail is pivoted to a rotating component and is provided with an elastic component. The rotation component may be stopped by the stop block naturally in the absence of outer forces, so that the middle rail cannot be drawn into the outer rail. The inner rail is provided with a pushing component. After the inner rail slides into the middle rail, the push component pushes the elastic component, then the elastic component drives the rotation component to rotate, so that the rotation component is released from the stop block and the middle rail can be drawn into the outer rail.

Description

Slide rail positioning device

The invention relates to a positioning device for a slide rail, in particular to a three-stage slide rail structure. After the middle rail is pulled out of the outer rail and positioned, even if the slide rail is impacted by an external force, the crushing damage will not occur. Positioning means.

The general server will install slide rails on both sides of the cabinet, so that the staff can easily pull the server out of the cabinet when the server needs to be repaired, and then push the server into the cabinet after the repair is completed. Common slide rails include inner rail and outer rail, and even a middle rail is provided between the inner rail and the outer rail to increase the movable stroke of the slide rail; the inner rail is used for combining with the sides of the server body, and the outer rail It is fixed on both sides of the cabinet; the inner and outer rails are slidingly matched so that the inner rail can slide back and forth relatively along the length of the outer rail; or the inner rail is slidably fitted to the middle rail, and the middle rail is slidably fitted to the outer rail .

In the case of a three-stage slide including an outer rail, a middle rail and an inner rail, when the inner rail completely pulls out the middle rail and the middle rail completely pulls out the outer rail, it is not arbitrary in order to stabilize the pulled-out servo. When moving back into the cabinet, a positioning device is generally arranged between the middle rail and the outer rail, so that the middle rail is completely pulled out of the outer rail and positioned immediately; however, the general rail positioning device is pulled out of the outer rail and positioned in the middle rail. After that, when a large external impact is encountered, the positioning device cannot withstand the external force and may cause collapse damage.

Taking Taiwan Patent Publication No. 201228568 as an example, a slide rail device is provided. An outer rail, a middle rail, an inner rail, a locking member mounted on the middle rail and an elastic member, the outer rail is provided with a supporting member and a fixing portion near the front end of the supporting member, and the fixing portion includes a limit portion a slot, the inner rail is provided with a card abutting portion, the locking member is provided with a first hook and a second hook, and the support member of the outer rail supports the first hook of the locking member to keep the locking member in a lock In the stop position, the second hook of the locking member blocks the latching portion of the inner rail, so that the middle rail and the inner rail are synchronously pulled forwardly out of the outer rail; when the locking member slides forward with the middle rail to the locking member When the first hook slides over the support member and falls into the limit slot of the outer rail, the elastic member resets and rotates the stop to an unlocked position, and the second hook of the lock member is disengaged from the latching portion of the inner rail. Unlock the inner and middle rails.

However, the aforementioned conventional patents are not only complicated in structure, but also have high manufacturing costs. After the rail is pulled out of the outer rail and positioned, when the sliding rail is hit by an external force, the abutting portion and the locking member are easily deformed, collapsed and damaged, and the durability is not good.

The object of the present invention is to solve the conventional three-stage slide rail structure applied to a servo. When the middle rail is pulled out of the outer rail and positioned by the positioning device, the positioning device is easy to generate when the slide rail is impacted by an external force. Deformation collapses and damage is missing.

The invention is characterized in that a stop block is arranged on the outer rail of the three-stage slide rail; a rotating component is arranged on the middle rail and an elastic component is arranged, and the center of gravity of the rotating component is used to make the rotating component have no external force In one state, one end is correspondingly blocked by the stopper and is strongly blocked, so that the middle rail cannot be folded on the outer rail, and the rotating member and the stopper have sufficient strength to withstand external force impact without collapse and damage. In addition, a pushing member is disposed on the inner rail, and when the inner rail slides completely into the middle rail, the pushing member pushes the elastic member to deform, and then the deformed elastic member pulls the rotating member to rotate away from the blocking of the stopper, so that The rail is folded and fully enters the outer rail Inside.

The slide rail positioning device of the present invention has a technical means including an outer rail and a slip a central rail that is combined with the outer rail, and an inner rail that is slidably coupled to the middle rail, wherein a main stop is provided on the inner side of the main rail; a main wall of the middle rail is provided with a perforation, and the main wall is inner a rotating member is disposed, and an elastic member is disposed, the rotating member has opposite first ends and second ends, the second end is provided with a protrusion and passes through the through hole, and the rotating member is in a state without external force The protruding portion corresponds to the side of the stopper by the center of gravity of the rotating member itself, the elastic member contacts the first end of the rotating member; the outer wall of the inner rail is provided with a pushing member; When the rail slides relative to the middle rail, causing the pushing member to elastically deform the elastic member, the deformed elastic member pulls the first end of the rotating member to rotate the rotating member, so that the protruding portion of the rotating member is disengaged from the stopper Blocking, allowing the middle rail to slide into the outer rail.

Based on the high strength of the projections that are subjected to the stop block, and the simplification of the structure In consideration, the protruding portion is formed by bending from the second end of the rotating member.

Based on allowing the elastic member to effectively pull the rotating member and is suitable for installation In the narrow slide rails to avoid interference with other elements, the elastic members are arranged in a zigzag elongated shape.

The elastic member can be smoothly pulled when the inner rail is slid into the middle rail, The invention forms a bevel for pushing the elastic member in the aforementioned pushing member.

Preferably, the protruding portion of the second end of the rotating member of the present invention is attached to the length of the slide rail The degree of direction is blocked by the side edges of the stopper, and therefore, the slide rail of the present invention can receive the maximum force in its longitudinal direction without causing crushing damage to the rotating member and the stopper.
