Fixing device arranged on upper cover of case and server

Abstract

The invention discloses a fixing device arranged on an upper cover of a case, and the device comprises: an upper cover lock, which is used for fixing the upper cover of the case; a base, which comprises an upper base and a lower base, wherein a gap is formed between the upper base and the lower base, the two sides of the upper base are provided with first inclined faces, the included angle between each first inclined face and the top face of the upper base is an acute angle, and the lower base is provided with a groove. a first sliding block, which is arranged in the groove and is provided with a second inclined surface, wherein the included angle between the second inclined surface and the top surface of the lower base is an obtuse angle; and a guide rod, wherein one end of the guide rod is arranged in the gap, one end of the guide rod is provided with a first sliding surface in sliding joint with the first inclined surface and a second sliding surface in sliding joint with the second inclined surface, and the other end of the guide rod is provided with a pin. When the upper cover lock is closed, the first sliding block is pushed to slide in the first direction so as to drive the guide rod to slide in the second direction. The invention further provides a server. According to the scheme provided by the invention, the upper cover body can be prevented from falling off from the case due to failure of the upper cover lock caused by large distortion and deformation when the depth of the case is relatively long.

Description

technical field [0001] The invention relates to the field of servers, in particular to a fixing device arranged on an upper cover of a chassis and a server. Background technique [0002] In the prior art servers and server products, two methods are mostly used to fix the upper cover of the server. One is for products that do not need to open the upper cover for maintenance, and directly lock the upper cover and the chassis together with screws. Although this design has high reliability, for customers to open the chassis more often, it needs to be removed with tools. The way of a few screws is hard to accept. As customers in the market pay more and more attention to fast operation and maintenance and better operation friendliness, another way to fix the upper cover through the tool-free upper cover lock device is more and more used in server products. This upper cover locking device uses the reaction force between itself and the fixing pins at the corresponding positions of...

AI Technical Summary

Problems solved by technology

[0003]Because one side of the gourd hole is open, when one side of the chassis is lifted, the chassis deformation is relatively large, especially when one corner is lifted, the top cover of the chassis will automatically pop open Hidden dangers

When the deformation of the chassis is large, it is easy to cause abnormal force on the board and other cards, and there will be functional hidden dangers
