Description
Technical Field
[0001] The utility model belongs to the technical field of server board fixing devices, and in particular relates to a tool-free installation board fixing device. Background Art
[0002] In recent years, as people's demand for high-performance servers has increased, as well as the requirements for data processing and transmission rates have become increasingly higher, the two sides of lightweight boards such as M.2 have begun to be filled with chips and components. At the same time, in order to meet the functional use requirements of high-power chips and components on lightweight boards such as M.2, heat dissipation covers are generally installed on the top and bottom surfaces of the boards.
[0003] At present, when installing the heat dissipation cover on the top and bottom of the existing M.2 and other light boards, the following two methods are mainly used: 1. Screw fixing method, that is, directly installing the heat dissipation cover on the top and bottom of the board through bolts and other fasteners; 2. Push pin method, that is, using mushroom heads and other snap structures to install it on the top and bottom of the board. However, both of the above methods have certain defects. Specifically, for the first screw fixing method, due to the small size of the light board itself, the limited space inside the server that can support the placement of the board, and the bolts and other fasteners need to be accurately positioned before fixing when the upper and lower heat dissipation covers are separated and fixed, it has the problem of low assembly and disassembly efficiency in the actual operation process; for the second push pin method, due to the problem that the mushroom head is difficult to disassemble after the board and the heat dissipation cover are fixed, and the cover pressure piece is easy to be damaged, it is easy to need to replace parts and return for repair during the process of disassembling the heat dissipation cover, and the problem that parts cannot be reused.

[0028] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the inner side of the upper spring piece 4 is provided with at least one upper convex bump 11 convex inwardly, and an upper hanging hole is provided above the upper convex bump 11; the inner side of the lower spring piece 5 is provided with at least one lower convex bump 15 convex inwardly, and a lower hanging hole is provided below the lower convex bump 15, one end of the C-shaped spring piece 7 is hung with the corresponding upper convex bump 11 and the upper hanging hole, and the other end of the C-shaped spring piece 7 is hung with the corresponding lower convex bump 15 and the lower hanging hole, and the upper spring piece 4 and the lower spring piece 5 are connected together through the C-shaped spring piece 7. At this time, the utility model can constrain the rotation angle between the upper cover plate 1 and the lower cover plate 2 through the hooking structure between the C-shaped spring piece 7 and the corresponding upper convex bump 11 and the lower convex bump 15, and ensure that the upper cover plate 1 and the lower cover plate 2 can be tightly buckled through the elasticity of the C-shaped spring piece 7 itself, so as to avoid the opening between the upper cover plate 1 and the lower cover plate 2 being too large.
[0029] In addition, if Figure 6 As shown, as a preference, the utility model further provides a limiting column 13 on the upper surface of the lower cover plate 2, and provides a guide column 12 on the lower surface of the upper cover plate 1, and enables the guide column 12 to contact the limiting column 13, so that the utility model can limit and constrain the position of the board 3 through the limiting column 13, and ensure that the position of the upper cover plate 1 meets the requirements through the cooperation between the guide column 12 and the limiting column 13.
