[0013] Furthermore, an avoidance hole is opened on the end surface of the back plate, and the avoidance hole is opposite to the installation area of ​​the heat dissipation module.

[0014] The utility model proposes a conveniently assembled graphics card structure, which has the beneficial effect that: in the utility model, by adopting a detachable structural design of the upper cover and the back plate, when it is necessary to clean and repair the internal heat dissipation module or fan unit, it is only necessary to remove the locking piece on the rear side of the back plate to complete the separation between the upper cover and the back plate, thereby exposing the internal PCB and heat dissipation module, etc., which greatly optimizes the convenience of assembly and disassembly, allowing ordinary users to easily disassemble and assemble the upper cover and back plate of the graphics card, making the product more playable, and at the same time will not cause damage or influence on the performance of internal components.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3An embodiment of the utility model discloses a conveniently assembled graphics card structure, which includes a PCB 1, a heat dissipation module 2 fixed on the PCB 1, and a fan unit 3 installed on the heat dissipation module 2. Specifically, in this embodiment, the PCB 1, the heat dissipation module 2, and the fan unit 3 are fixed by bolts to form a whole to be installed;

[0021] An upper cover 4 is provided on the top of the fan unit 3, and a hole 41 for avoiding the installation of the fan unit 3 is provided on the end surface of the upper cover 4, and a back plate 5 is provided on the lower side of the PCB 1;

[0023] In some embodiments, the positioning structure 6 in the utility model includes at least two positioning pins fixed on the upper end of the back panel 5, and a positioning hole is opened on the end face of the PCB1, and the positioning hole is not shown in the figure. The positioning pins are plugged into the positioning holes for positioning, that is, when assembling the back panel 5, the positioning pins on the back panel 5 are plugged into the positioning holes on the PCB1 to achieve the positioning assembly between the back panel 5 and the above-mentioned PCB1 as a whole.

[0024] On the basis of the above embodiment, the fixing structure 7 includes a plurality of connecting columns 71 fixed to the lower side of the upper cover 4, and a plurality of docking columns 72 are fixed to the upper end of the back plate 5. The docking columns 72 are in contact with the connecting columns 71 and are fixed by locking members 73. Preferably, the locking members 73 are bolts. After further assembling the back plate 5, the upper cover 4 is covered on the top of the heat dissipation module 2, and then the connecting columns 71 are aligned with the docking columns 72, and bolts are inserted into the inside of the docking columns 72. In this embodiment, a threaded hole is opened in the inside of the connecting column 71, and the connection and fixation of the upper cover 4 and the back plate 5 are completed by threaded connection between the bolts and the threaded holes.

[0025] Furthermore, in this embodiment, a countersunk hole is provided on the end face of the back plate 5, and the countersunk hole is connected to the inner hole of the docking column 72. The locking member 73 enters along the countersunk hole and is fixed to the connecting column 71.
