Description

Slide rail positioning mechanism

The invention relates to a positioning mechanism of a slide rail, in particular to a three-stage slide rail structure, when the inner rail is pulled out of the middle rail, the lock can be accurately obtained without leaving the middle rail, when the inner rail is to be pushed When entering the middle rail or separating the inner rail from the middle rail, the operator can be quickly and easily operated.

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. After the repair is completed, the server is pushed into the cabinet, or even the server. Remove from the cabinet. 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 order to prevent the servo from being dropped when the servo is pulled out of the cabinet, the positioning mechanism is usually arranged between the inner rail and the middle rail, so that the inner rail is used as the inner rail. After the middle rail is completely pulled out, the positioning mechanism is used for immediate positioning to avoid the inner rail from being disengaged from the middle rail, and the server is detached and dropped; however, the general rail positioning mechanism is a two-link composite mechanism or a single elastic piece. The hook mechanism; the two-link composite mechanism is mostly shrapnel parts, which has many manufacturing steps and high cost; the single shrapnel hook mechanism has weak strength and is easily damaged and damaged by a large external force.

Taking Taiwan Patent No. M350226 as an example, a slide rail having a snap structure is provided, comprising an outer slide rail and an inner slide rail slidable relative to the outer slide rail, wherein the outer slide rail is provided with a stepped groove, The inner slide rail is provided with a slider which can slide along the inner slide rail and is inserted into the stepped slot to fix the inner slide rail and the outer slide rail, and a long pull rod which is slidably mounted on the inner side of the inner slide rail. The long pull rod is provided with an inclined surface, and the long pull rod is pulled in a first direction away from the outer slide rail, and the inclined surface pushes the slider to slide the slider in a second direction perpendicular to the first direction and can The inner slide rail is separated from the outer slide rail.

The aforementioned conventional patent is a positioning mechanism of a typical single elastic hook. When the inner rail is pulled out of the middle rail and positioned, when the sliding rail is impacted by an external force, the hook is easily deformed 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 the server. The positioning mechanism belongs to the two-link composite mechanism, and the cost is high; and the single elastic hook mechanism is weak. When the slide rail is hit by an external force, it is prone to deformation and collapse and damage.

The feature of the invention is that a positioning block is arranged on the middle rail of the three-stage slide rail, and a positioning unit and a release link are arranged on the inner rail, and the positioning unit can be stabilized when the inner rail is completely sliding out of the middle rail.
