Description

Ultra-thin servo slide rail universal type snap positioning device

The present invention relates to a snap positioning device for a slide rail, and more particularly to a slide rail that can be more conveniently, safely and durablely mounted to a server cabinet.

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.

The rail is installed in the cabinet. Generally, the rail slot is disposed on both sides of the cabinet for accommodating the server, and the outer rail of the rail slides along the rail slot into the cabinet, and the outer rail completely enters the rail slot. After that, the outer rail is fixed to the cabinet by using a mosaic structure including a spring piece and a buckle hook to prevent the outer rail from being detached from the cabinet.

In order to obtain a more stable positioning after the slide rails are assembled in the cabinet, the conventional slide rails are provided with a positioning structure including a spring piece and a buckle hook, and a positioning structure is also provided at the end of the slide rail and the end of the rail groove. The first positioning unit disposed at the end of the sliding rail and the second positioning unit disposed at the end of the rail slot, the first positioning is made when the sliding rail slides along the rail slot to the end The bit unit and the second positioning unit are cooperatively positioned with each other, and then the hook is fastened to the end of the track groove to be fixed.

The conventional first positioning unit is generally a protruding column disposed at an axial end of the sliding rail, and the conventional second positioning unit is disposed at an end of the rail groove and corresponding to the protruding column. The end face of the stud is generally circular or square, and the hole is a corresponding circular hole or square hole; some conventional structures are locked with a cylindrical positioning tip into the end of the sliding rail. The hole is used as the protruding post, and the rear end of the rail groove is provided with a positioning hole corresponding to the positioning tip; when the sliding rail slides along the rail groove to the end, the cylindrical protruding column is inserted into the circular hole, or the square is made. The stud is inserted into the square hole for positioning, or the positioning tip is inserted into the fixed hole for positioning, and then the hook is fastened to the end of the rail groove to be fixed.

However, the conventional sliding rails and the cabinet rails are mostly fixed on the outside of the cabinet inlaid rails. However, if the latching method is to pull the server out of the cabinet, the shrapnel needs to be moved to release the hooks to the rails. When it is fixed, it is easy to cause the permanent deformation of the shrapnel due to the excessive force applied by the operator and it cannot be used. In addition, when the rail groove is provided with a circular hole, the protrusion column provided on the slide rail for engaging with the hole hole must also be set to a cylindrical shape; and when the rail groove is provided with a square hole hole, the slide rail is provided for The studs to which the holes are matched must also be square-column; or when the troughs are provided with smaller positioning holes, they must be used with the corresponding positioning tips, which cannot be used interchangeably with each other, especially for ultra-thin type. In terms of servo rails, it is impossible to provide a positioning structure that can be shared by a circular hole, a square hole or a smaller positioning hole because of the limited area of the end portion.

Taking Taiwan Patent Publication No. 201446116 and U.S. Patent Publication No. 2010/0072153 as an example, it is disclosed that a square stud is provided at the end of the slide rail, and a square hole corresponding to the square stud is provided on one of the trailers, and the slide rail is slid into the slide rail. After the end of the rail groove, the square stud is inserted into the square hole to generate positioning.

Taiwan Patent Publication No. 201408241 discloses a circular boss at the end of a slide rail, and a circular hole corresponding to a circular stud in a trailer, which is used after the slide rail slides into the end of the rail groove. The column is inserted into a circular hole to create a positioning.

However, these conventional patents have the above-described different shapes of positioning structures that cannot be used interchangeably, and are not suitable for the problem of ultra-thin servo rails.

The purpose of this creation is to provide a slide rail suitable for mounting on an ultra-thin server, and can be positioned in cooperation with a trailer having a circular hole, a square hole or a positioning tip, which is more compact, easier to use and durable.
