Description

Sliding rail limiting device for server case

Technical Field

The utility model belongs to the technical field of the server and specifically relates to a can realize spacing server machine case slide rail stop device of slide rail, realize the spacing of tray, improve the reliability of server.

Background

With the rapid development of the server industry, the number of hard disks applied to the server for realizing a large capacity is also sharply increased. Unified management of putting hard disks into Tray is a very common design of server design. The number of the hard disks is obviously increased, the total weight of the Tray is increased, the reliability risk of the whole server is increased, and particularly, the sliding rail for providing fixing and limiting functions for the Tray must have enough strength and rigidity to ensure the fixing and limiting effects of the Tray and the built-in hard disk set of the Tray.

The quick-witted case provides overall structure's support among the current quick-witted case structural design, and Tray is fixed, spacing only relies on spacing on the slide rail to provide, and the server is experiencing reliability experiment or when actual transportation, installation, application, can bear the impact acceleration effect that comes from all directions, and these impact forces are all finally born by spacing on the slide rail, easily make spacing on the slide rail inefficacy, have increased the reliability risk of server, consequently need for a limit structure to improve the reliability level of server urgently.

Disclosure of Invention

In order to overcome not enough among the above-mentioned prior art, the utility model provides a server machine case slide rail stop device can combine with the spacing of slide rail self, forms spacing, the end position to the tray, the terminal displacement of effectual restriction tray production under the impact acceleration effect.

In order to achieve the above object, the utility model provides a slide rail limiting device for a server case, which comprises a case, a tray and a slide rail; the outer guide rail of the slide rail is fixed on the side wall of the case, and the inner guide rail of the slide rail is fixed on the tray; therefore, the chassis can realize the movable connection of the tray through the slide rail, and the tray can slide along the direction of the slide rail; and a limiting plate is arranged on the side wall of the case at the tail end of the slide rail and used for limiting the inner guide rail of the slide rail. The limiting plate at the tail end of the sliding rail can limit the tray through limiting the inner guide rail, and the tray can be prevented from sliding out of the case.

And one side of the limiting plate, which faces the slide rail, is provided with a limiting bulge, and the limiting bulge is arranged at one end, which is far away from the side wall of the case, of the limiting plate. The inner guide rail of the slide rail can be prevented from horizontally moving, when the slide rail is used, when the inner guide rail receives the limiting plate, the inner guide rail is easy to deflect, and then the inner guide rail is separated from the outer guide rail, so that the limiting protrusion can play a role in limiting, and the inner guide rail is prevented from deflecting.

The limiting plate sets up the blotter towards one side of slide rail, can play the cushioning effect like this, absorbs some impact forces, avoids the inner rail to damage, can increase of service life.

The case is U-shaped, and two side walls of the case are connected with the tray through sliding rails respectively. This maintains the stability of the tray.

Set up travel switch below the limiting plate, travel switch and alarm are established ties, have the alarm lamp with the alarm is parallelly connected, sets up travel switch, is a redundant setting, and when the limiting plate damaged, the inner guide rail can be rushed out, will touch travel switch like this, and alarm lamp will send the warning, remind the staff, and the alarm can set up according to the in-service use needs with setting up the position of alarm lamp, concatenates on power supply after travel switch establishes ties with the alarm, and the alarm lamp is parallelly connected with the alarm, and power supply can select the setting according to the scene.

Set up the through-hole on the quick-witted case lateral wall of limiting plate top, through-hole shape size is the same with the limiting plate, like this when processing the limiting plate, can directly use former quick-witted case, and the sheet metal component punching press obtains the limiting plate on former quick-witted case lateral wall, does not use the limiting plate to do, can be with the limiting plate during the through-hole of turning back, can not increase extra cost.

According to the technical scheme, the utility model has the advantages of it is following: the right lateral displacement of the tray under the action of impact acceleration can be effectively limited. Because the panel of quick-witted case is thick, the structural strength, the rigidity of the limiting plate that obtains through quick-witted case lateral wall sheet metal component punching press are obviously higher than spacing in the slide rail, and the slide rail is because factors such as panel thickness, space size are limited restrict, and the mechanism intensity of stopping is limited. And the limiting plate is formed by stamping the sheet metal part on the side wall of the case in a stamping mode, so that the processing is easy, the cost is saved, and the additional cost is not increased.
