[0021] Please refer to Figures 1-4 , an embodiment provided by the present utility model: a tool-free disassembly and assembly graphics card fastening structure, including a rear plate body 1. A graphics card fixing frame 2 is fixedly installed on the inner and outer walls of the rear plate body 1. A plurality of evenly distributed graphics card slots are formed on the outer surface of the graphics card fixing frame 2. A lower socket 3 is provided at the bottom end of each graphics card slot. A pressing plate 5 is rotatably installed on the upper outer wall of the graphics card fixing frame 2 through a rotating shaft 4. A torsion spring 6 is sleeved on the rotating shaft 4. With this structural design, the pressing plate 5 can be manually rotated to open upward. After releasing the pressing plate 5, the pressing plate 5 can be pressed down and reset under the drive of the torsion spring 6, so as to tightly fix the lower structure through the resilience effect of the torsion spring 6;

[0022] A graphics card body 10 is arranged in the graphics card slot. A fixing card plate 7 is fixedly installed at the top end of the graphics card body 10 through a screw. A lower plug-in 8 adapted to the lower socket 3 is fixedly connected below the fixing card plate 7. An upper bent plate 9 is fixedly connected above the fixing card plate 7. The fixing card plate 7 and the upper bent plate 9 are perpendicularly arranged to each other;

[0023] With this structural design, the graphics card body 10 can be fixed on the fixing card plate 7 to form an installation assembly structure of the graphics card. During installation, the pressing plate 5 is manually rotated upward to open. At this time, the fixing card plate 7 of the graphics card body 10 is slid down from top to bottom, so that the lower plug-in 8 at the bottom end of the fixing card plate 7 is inserted into the lower socket 3, thereby completing the bottom limit fixing effect of the graphics card body 10 through the cooperation and insertion of the lower plug-in 8 and the lower socket 3, and avoiding the shaking of its bottom;

[0024] After the lower plug-in 8 of the fixing card board 7 is completely inserted into the lower slot 3, at this time, the upper bending plate 9 can be exactly placed on the upper surface of the graphics card fixing bracket 2 and contact with it.

[0025] In this embodiment, for the convenience of production and processing, the fixing card board 7, the lower plug-in 8 and the upper bending plate 9 are designed with an integrally formed structure.

[0026] In this embodiment, in order to fix the fixing card board 7, a fixing notch 11 is opened on the outer wall of one side of the upper bending plate 9;

[0027] Among them, a number of uniformly distributed fixing holes are opened on the upper surface of the graphics card fixing bracket 2;

[0028] With this structural design, when the lower plug-in 8 of the fixing card board 7 is completely inserted into the lower slot 3, at this time, the bottom surface of the upper bending plate 9 contacts the upper surface of the graphics card fixing bracket 2, and at the same time, the fixing notch 11 is aligned with the fixing holes opened on the graphics card fixing bracket 2. After that, a rubber plug is inserted into the hole to complete the fixing and limiting work of the upper bending plate 9, so as to complete the fixing and installation effect of the graphics card body 10.

[0029] Working principle: When the graphics card body 10 needs to be installed, manually rotate the pressing plate 5 upward to open it. At this time, slide the fixing card board 7 of the graphics card body 10 from top to bottom, so that the lower plug-in 8 at the bottom of the fixing card board 7 is inserted into the lower slot 3, so as to complete the bottom limit fixing effect of the graphics card body 10 through the cooperation and insertion of the lower plug-in 8 and the lower slot 3, and avoid the bottom of it from shaking;

[0030] After the lower plug-in 8 of the fixing card board 7 is completely inserted into the lower slot 3, at this time, the bottom surface of the upper bending plate 9 contacts the upper surface of the graphics card fixing bracket 2, and at the same time, the fixing notch 11 is aligned with the fixing holes opened on the graphics card fixing bracket 2. After that, a rubber plug is inserted into the hole to complete the fixing and limiting work of the upper bending plate 9, so as to complete the fixing and installation effect of the graphics card body 10;

[0031] After that, release the pressing plate 5. After the pressing plate 5 is released, the pressing plate 5 can be rotated and reset under the drive of the torsion spring 6, so as to press the lower bending plate 9 below through the elastic return effect of the torsion spring 6, improve the graphics card fixing effect, and have a good elastic pressing effect;

[0032] When disassembling, simply manually rotate the opening pressure plate 5, then pull out the rubber plug, and then draw out the fixed clamping plate 7 from the lower slot 3 to complete the overall disassembly of the graphics card body 10. No installation tools such as screwdrivers are required for assembly and disassembly, which has a good tool-free disassembly and assembly effect, effectively reducing the disassembly and assembly limitations restricted by tools during assembly and disassembly. The structure is convenient to use, the installation and disassembly process is fast, with a quick installation and quick disassembly effect, improving the efficiency of structure replacement or maintenance. The structure has high convenience and good practicality.

[0033] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
