Description

Technical Field

[0001] The utility model relates to the field of GPU fixing, in particular to a GPU fixing device for a multi-graphics card server. Background Art

[0002] CPU+GPU hybrid servers are increasingly being used. Considering the reliability of the transportation process, most GPUs are shipped separately rather than being placed inside a chassis for transportation as a whole. The GPUs are assembled into the chassis after the equipment arrives at the customer's room. For example, Chinese patent CN217034682U discloses a GPU fixing device for a multi-graphics card server, comprising a fixing frame with a slide groove on the inside and symmetrical positioning grooves extending through the slide groove on the top of the fixing frame. The GPU fixing members are provided with multiple groups, including a GPU bracket slidably connected to the slide groove, a positioning hole corresponding to the positioning groove on the GPU bracket, and an embedding groove adapted for the GPU in the GPU bracket. The positioning pins are engaged with the positioning groove and the positioning hole. By moving the GPU bracket in the slide groove, when the position of each GPU is determined, the positioning pins are inserted into the positioning groove and engaged with the positioning hole to fix the position of the GPU bracket. The GPU bracket is then fixed by embedding the GPU into the embedding groove. The above structure is fixed by buckles and multiple snap-on components, which is relatively cumbersome during installation. Therefore, we propose a GPU fixing device for a multi-graphics card server. Utility Model Content
