Description

Sliding rail support suitable for server cabinet in wider range

Technical Field

The utility model belongs to the technical field of server cabinet sliding rails, and particularly relates to a sliding rail support suitable for a wide range of server cabinets.

Background

The chassis of the server is mounted on the server cabinet by virtue of the server chassis sliding rails on two sides of the chassis, so that the server can be pulled out or pushed in the cabinet, and the server is convenient to overhaul or replace. The connection between the server case slide rail and the server cabinet is realized by the clamping fit of the pin posts on the front and rear brackets of the slide rail and square mounting square holes on two sides of the cabinet.

The existing server case slide rail mostly adopts two structural forms of detachable or spring guide posts on the front bracket and the rear bracket. Moreover, because the center distances of square holes on two sides of the server cabinet often deviate due to the processing technology problem (for example, the horizontal hole distances (center distances) of square holes on two sides are 465mm, the maximum possible deviation is 3 mm), however, the height and width dimensions of the server cabinet are fixed, so the applicant tries to make the transverse movement amount capable of meeting the positive and negative errors of the horizontal hole distances of the square holes on two sides of the server cabinet exist between the opposite slide rail brackets on two sides in the server cabinet, thereby meeting the requirement that the server cabinet can be always installed on the server cabinet with the square hole center distance deviation through the slide rail of the current server cabinet.

However, in the practical use process, the user finds a new problem of the solution (see fig. 1-2, reference symbol a is a slide rail outer frame, reference symbol B is a slide rail inner frame in the drawing), that is, after the slide rail outer frame is assembled to the server cabinet through the slide rail bracket, and before the slide rail inner frames on two sides of the assembled server cabinet are spliced with the slide rail outer frame, the slide rail outer frame and the slide rail bracket incline outwards due to the action of gravity, so that the slide rail outer frames on two opposite sides are in an angle of eight shapes. This makes it impossible to insert the inner rail frames on both sides of the rack into the outer rail frames already assembled on both sides of the rack when the rack is installed, which results in an increased difficulty in installing the rack and in extreme cases even in damage to the racks.

The rear end of the guide pillar 408 is fixedly connected with the guide pillar fixing plate 104 through the guide pillar fixing piece 410, the front end of the guide pillar 408 passes through the special-shaped sliding sleeve through hole 103 forwards, the special-shaped sliding sleeve 407 is sleeved at the front part of the guide pillar 408, the second spring 409 is sleeved at the middle rear part of the guide pillar 408, the rear end of the second spring 409 is connected with the guide pillar fixing plate 104, the front end of the second spring 409 is connected with the special-shaped sliding sleeve 407, the special-shaped sliding sleeve 407 protrudes forwards from the special-shaped sliding sleeve through hole 103 along the guide pillar 408 under the action of the second spring 409 and is limited by the outer baffle 9, so that the pin 4 is correctly assembled on the front end face of the sliding rail bracket body 1, namely, the pin 4 does not have a moving amount in the Z direction in the mounting direction but has a moving amount in the X direction in the mounting direction hole 3.

When the pin 4 is assembled on the front end face of the sliding rail bracket body 1, two planes of the racetrack cross section of the special-shaped sliding sleeve 407 must be located in the X direction, and two circular arc surfaces must be located in the Z direction, so that the shape and size of the special-shaped sliding sleeve via hole 103 formed on the front end face of the sliding rail bracket body 1 are matched with the shape and size of the racetrack cross section of the special-shaped sliding sleeve 407, and the racetrack opening of the special-shaped sliding sleeve via hole 103 corresponds to the position angle required to be aligned by the racetrack cross section of the special-shaped sliding sleeve 407, so that the position angle of the racetrack cross section is always in the aligned position angle when the special-shaped sliding sleeve 407 slides on the guide pillar 408.

In addition, the embodiment can be compatible with the assembly of a small installation square hole due to the adoption of the spring guide column type pin design. The cross section of the guide post 408 may be circular, which allows this embodiment to have a horizontal amount of play only when assembled with a large-sized mounting square hole. The cross section of the guide post 408 may also be a racetrack-shaped cross section corresponding to the special-shaped sliding sleeve 407, and when the guide post 408 is fixed on the sliding rail bracket body 1, the racetrack-shaped cross section of the guide post 408 is also in the X direction with two long faces and the Z direction with two short faces, so that the embodiment can have the activity in the X direction no matter when being assembled with a large-size installation square hole or a small-size installation square hole.

In the application of the four embodiments, the offset of the residual transverse movement amount of the installed server cabinet in the X direction and the limit of the installed server cabinet in the Y direction are realized through the matching of the X-direction elastic sheet and the Y-direction limit block component. Therefore, when the utility model is practically applied to the installation of the server cabinet and the server cabinet, the obvious sinking amount of the server cabinet is not existed in the Z direction, the horizontal width error between the width of the server cabinet and the horizontal hole pitch of the installation square hole of the server cabinet can be compensated in the X direction during the installation, and the Y direction can be limited after the server cabinet is installed and the residual transverse movement amount in the X direction can be counteracted, thereby meeting the compatible installation requirements of the server cabinet on the server cabinets with different horizontal hole pitches of the installation square hole, improving the application range, effectively avoiding the inclination of the sliding rail bracket body and the sliding rail outer frame on the server cabinet, realizing the rapid and accurate insertion of the sliding rail inner frame method into the sliding rail outer frames assembled on the two sides of the server cabinet, and greatly reducing the difficulty of the installation of the server cabinet installed on the server cabinet.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
