Description
Technical Field
The embodiment of the invention relates to the field of structures, in particular to a fixing device and a chassis.
Background
With the continuous progress of electronic technology, electronic devices are an integral part of life. Personal computers, mainframe computers, and server systems have many internal components, and PCI-E cards are one of the components described above. The peripheral component interconnect interface (Peripheral Component Interconnect-Express, PCI-E) is a new generation bus interface known as third generation I/O bus technology. Therefore, there are many PCI-E cards with different functions in each computer case, but most PCI-E cards in the case are not fixed by tail or are fixed by screws as a whole.
Fig. 1 shows a schematic structural diagram of a fixing device in the prior art according to an embodiment of the present invention, as shown in fig. 1, including a main chassis 101, a PCI-E card 102 and a fixing structure 103, where the PCI-E card 102 and the fixing structure 103 are in the main chassis 101, and as shown in the drawing, the PCI-E card is only fixed at the head and not at the tail, because the length of the PCI-E card is relatively long, if the PCI-E card is only fixed at the head, when the card vibrates, the PCI-E card itself will deform or easily fall off, and the fallen card contacts the motherboard, thereby damaging components.
Fig. 2 shows a schematic structural diagram of a fixing device according to the prior art, as shown in fig. 2, including a main chassis 201, a PCI-E card 202, a fixing structure 203, and fixing screws 204, wherein the PCI-E card 202 and the fixing structure 203 are in the main chassis 201, and the fixing structure 203 fixes the PCI-E card 202 through the fixing screws 204. As shown, the PCI-E card is integrally screwed, which reduces the flexibility in PCI-E card replacement or repair, and, secondly, requires additional mating tools for screw removal.
In view of the prior art, there is a need for a corresponding solution to meet the user's need for PCI-E card fixation.

Wherein, in the case that the fixing member 304 fixes the member to be fixed, the member to be fixed is inserted into the card slot 305; in the case where the fixing member 304 does not fix the member to be fixed, the blocking portion 303 is located inside the fixing member 304.
